Yes, I had a Yaesu FT7100 a couple of years ago that had 2 receivers. I bought it figuring it would do full duplex, but it didn't. Wish Yaesu would come out with a replacement for the FT847. Something like the FT991A but that does full duplex. 50 watts on VHF and UHF would be fine. Also wish they would replace the FT857, a mobile sized radio that does HF/VHF/UHF. And make it easier to use than the FT891. I usually don't complain about ergonomics but the setup of the FT891 was bad. The noise reduction would turn off and the width would reset to default every time you changed bands or even VFOs in the same band. And the method for changing bands and modes was just stupid 73 John AF5CC Sent using {0} ---- On Fri, 23 Aug 2024 21:33:31 -0500 Frank Karnauskas (N1UW) via AMSAT-BB <amsat-bb(a)amsat.org> wrote --- Greetings, All.

Just had a couple of good contacts with K8DP and KB2MFS with great results. Very strong downlink and very sensitive receiver. I was able to hold the transponder with 10 watts for almost the entire pass. It was a western pass for me with a maximum of 38 degrees elevation..

(***) Watch for Livestream at https://www.instagram.com/gds_meschede/ Fasta Villa Eucaristica School, Cordoba City, Argentina, direct via LU1HKO The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Matthew Dominick KCØTOR The ARISS mentor is VE6JBJ Contact is go for: Fri 2024-08-30 15:29:39 UTC 42 deg The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-08-23 19:00 UTC.

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-08-22 19:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-08-22 19:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

Thank you Doug for making me aware for the possible scenario which may happen at my end. I will try with not so busy pass in beginning as you suggested. Btw my setup is 100% portable, I shall be operating from my rooftop or field, so need some time to be comfortable with it. Also I will schedule my activity, not all passes will be possible for me to work! Re. chasing your grid EN62VT with IO-117 we do get small window with pass of approx 5° or so. Will try our luck very soon.

Upcoming ARISS Contact Schedule as of 2024-08-19 20:00 UTC Quick list of scheduled contacts and events: Bayou Academy, Cleveland, MS, direct via W5YD The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Sunita Williams KD5PLB The ARISS mentor is K4RGK Contact is go for: Thu 2024-08-22 16:43:06 UTC 80 deg Watch for Livestream at https://www.youtube.com/live/PzZuhb1bGiw https://live.ariss.org/ Gymnasium der Stadt Meschede, Meschede, Germany, direct via DRØZ The ISS callsign is presently scheduled to be OR4ISS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Sunita Williams KD5PLB The ARISS mentor is IN3GHZ Contact is go for: Fri 2024-08-23 08:05:04 UTC 45 deg Watch for Livestream at https://www.instagram.com/gds_meschede/ (***) Fasta Villa Eucaristica School, Cordoba City, Argentina, direct via LU1HKO The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Matthew Dominick KCØTOR (***) The ARISS mentor is VE6JBJ Contact is go for: Fri 2024-08-30 15:29:39 UTC 42 deg (***) The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-08-19 20:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-08-18 03:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

I have two of these, both running DSB capable firmware, but haven’t tried it out yet because tuning by up and down pushbutton would be very tricky to actually work. And yes, the transmit provides both side bands, so this would theoretically work. 73, Paul, N8HM On Sun, Aug 18, 2024 at 13:15 JOHN GEIGER via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > Has anyone used the Quansheng UV-K5 or k6 (or other variants) on the > satellites yet, especially the linear satellites?

Quansheng UV-K5/K6 on satellites
by JOHN GEIGER 18 Aug '24

18 Aug '24

Has anyone used the Quansheng UV-K5 or k6 (or other variants) on the satellites yet, especially the linear satellites? I see that there are now firmware mods to these HTs that not only allow for SSB reception-but also SSB transmission on 2m and 70cm. It is actually Double Side Band supressed carrier but several Youtube videos show it working well on 2m USB. So, since the satellites conventionally use LSB for the uplink, wouldn't the DSB transmit audio also provide a LSB signal that would be inverted to USB by the satellite? I wouldn't expect stellar performance out of these HTs but I do think a pair of them could make a budget friendly portable SSB station for some grid activations. Using them would be better than being QRT while in that grid because you couldn't afford a pair of FT817s or IC705s 73 John AF5CC Sent using {0}

What happened to Greencube IO-117?
by Rajesh Vagadia - VU2EXP 18 Aug '24

18 Aug '24

Dear all, Few months back I was trying to work Greencube Satellite with my limited setup, I was able to receive signal packets & telemetry with my 7 ele uhf Arrow antenna, though I could never Transmit & successfully trigger this Bird, perhaps my IC-705 limited 10W power was the issue. Now I am equipped with a new High gain cross yagi (14ele) to test & try Greencube! I observed since more than a week Greencube is not QRV! Can anyone give idea what happened to this beautiful bird? I am quite eager to work via this satellite from my grid ML52JH. I would also like to get response/guidance from user with Icom IC-705 who worked this bird successfully. Thank you in advance. 73 Rajesh P. Vagadia VU2EXP Rajkot - Gujarat India Regional Coordinator •AMSAT-INDIA •Amateur Radio Society of India

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-08-18 03:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-08-18 03:00 UTC. (***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

Set Screw for G5500 rotor cable connectors
by Stephan Greene 18 Aug '24

18 Aug '24

Does anyone know the size of the setscrew in the NJC-207-PF 7-pin rotor cable connector housing used for the Yaesu G5500? The NJC data sheets & drawings I found do not include this information, and my thread gauges don't go small enough. I'm assuming a metric thread. Thanks! 73 Steve KS1G

The following candidates have been duly nominated: - Mark Hammond, N8MH - Frank Karnauskas, N1UW - Bruce Paige, KK5DO - Paul Stoetzer, N8HM - Douglas Tabor, N6UA As three seats on the Board of Directors are up for election this year, the three candidates receiving the largest number of votes shall be declared elected to the seats. The two candidates receiving the next largest number of votes shall be declared First Alternate and Second Alternate, respectively. The voting process is now underway. AMSAT members can find candidate statements and electronic voting information on AMSAT's Wild Apricot Membership Portal <https://launch.amsat.org/2024-BoD-Election>. The voting period will conclude on September 15th and results will be announced no later than September 30th. *[ANS thanks Jeff Davis, KE9V, AMSAT Secretary for the above information]* ------------------------------ AMSAT Mail Alias Service to End August 31, 2024 A long-standing member service, the AMSAT Mail Alias Service is scheduled to end on August 31, 2024. A mail alias on AMSAT.ORG permitted people to send an email to members without knowing their actual internet email address. They just needed to know their amateur radio callsign. Unfortunately, the unchecked rise in domain name hacking and email account high-jacking has made it impossible to sustain this service at a cost-effective level. The number of callsign(a)amsat.org email accounts that had been hijacked and converted to zombie spam accounts over the years had led many internet service providers and gateway centers to ban all @ amsat.org email addresses, including those business accounts of AMSAT officers and officials. The tireless efforts of AMSAT’s all volunteer IT staff has worked for years to repair much of the damage, but AMSAT still get complaints from members who are not getting their personal emails, ANS bulletins or AMSAT-BB posts because of persistent delivery problems. It has come to the point where the AMSAT volunteer IT staff can no longer keep up with the maintenance requirements to keep the alias mail list clean and to work with email gateways to remove blocks. And, after considerable investigation into alternative paid email services, AMSAT leadership decided that the money required to keep an email alias system alive would be better spent on building and flying satellites for its members. Persons using the Mail Alias Service should begin to migrate to different email accounts so they do not lose receipt of personal emails, AMSAT News Service Weekly Bulletins, AMSAT-BB posts, or official messages from AMSAT itself. Members are especially asked to make sure they are NOT using a callsign(a)amsat.org as their registered email address in the AMSAT membership portal. Members can easily change their registered member email address by logging into the portal and updating their profile. *[ANS thanks the AMSAT IT Team for the above information]* ------------------------------ *The 2024 Coins Are Here Now!Help Support GOLF and Fox Plus.**Join <https://www.amsat.org/join-the-amsat-presidents-club/> the AMSAT President’s Club today!* ------------------------------ Changes to AMSAT TLE Distribution for August 16, 2024 Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/ The following satellites have been removed from this week's AMSAT TLE distribution: KASHIWA NORAD Cat ID 59508 Decayed from orbit on or about 10 August 2024 SPROUT NORAD Cat ID 39770 Decayed from orbit on or about 11 August 2024 *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, for the above information]* ------------------------------ *Need new satellite antennas?

Philippe, EA4NF will be QRV (*as KE4NF*) from *EL94* 13-17 Aug, then *EL95* 25-27 Aug. Looks like this will be FM LEO only. *Log as KE4NF.* In between these two activations, Philippe will activate Grenada (FK92) as J38NF on FM satellites, August 18-23. *Log as J38NF.* *[ANS thanks Ian Parsons, K5ZM, AMSAT Rover Page Manager, for the above information]* ------------------------------ * Want to fly the colors on your own grid expedition?* Get an AMSAT car flag and other neat stuff from our Zazzle store <https://www.zazzle.com/store/amsat_gear>! 25% of the purchase price of each product goes towards Keeping Amateur Radio in Space ------------------------------ AMSAT Ambassador Activities AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events. AMSAT Ambassador Clint Bradford, K6LCS, says, "Think a 75-minute presentation on "working the easy satellites" would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!"

Shanghai Spacecom Satellite Technology (SSST)’s new constellation, translated as "Thousand Sails," may grow to as many as 14,000 satellites. It joins potentially two other under-development broadband Chinese megaconstellations, each proposing over 10,000 satellites, in competition with OneWeb, Kupier, and Starlink. Unfortunately, the LM-6A’s upper stage appears to have malfunctioned and scattered over 700 pieces of space debris in a fairly high 800 km orbit (again). The debris at this altitude will likely take about a century for orbital decay. (ANS thanks The Orbital Index for the above information) + Orbital Space has announced its Lunar Program to send a student-built experiment to the Moon, marking the Arab world’s first privately funded lunar mission. The experiment by students from AGH University of Science and Technology in Poland focuses on analyzing interactions between lunar regolith and various materials that could be used in making cables and connectors for future lunar missions. Astrobotic will carry the payload on its third lunar mission aboard a Griffin-class lunar lander, targeting launch no earlier than Q4 2026. (ANS thanks Spacewatch Global for the above information) + The 2024 Olympic Games officially began in Paris, France on July 26, with athletes coming from around the world to compete. Meanwhile, above the world — on our orbiting laboratory, the International Space Station — NASA's astronauts got into the Olympic spirit. Check out their training montage from space, followed by a message to Earth from astronaut Matt Dominick at https://www.youtube.com/watch?v=ycDoaIn6wuk (ANS thanks The Orbital Index and NASA for the above information) + From Dave, G4DPZ, regarding the FUNcube Data Warehouse: "Our hosting provider has told us that they will be migrating our services to a new virtual machine on the 1st of September. Unfortunately the versions of the MySQL database server and Java runtime available on the new instance are not compatible with the current application implementation. Therefore I have to rebuild the development tool chain and migrate the application to suit the new instance. The work is underway but may take us into early September. We do know that database table migration works as we have already done a test of migrating the several GB of database between machines. If we do have any outage, the dashboards will upload when they detect the new instance is alive." (ANS thanks Dave Johnson, G4DPZ, Hon. Sec., AMSAT-UK, for the above information) + The SpaceX Transporter-11 rideshare mission launched 116 payloads from Vandenberg Space Force Base in California on August 16th. Four of these payloads carry transmitters on amateur bands. NIGHTJAR and TORO carry amateur UHF transmitters, but are not IARU coordinated. QUBE carries an amateur UHF transmitter, but its IARU coordination was declined. ORESAT0.5 is the sole IARU coordinated amateur mission on this launch with downlinks of 436.500 MHz and 2422.0 MHz. More information about ORESAT can be found at https://www.oresat.org/satellites/oresat0-5. Discussion regarding this launch can be found on the LibreSpace forum at https://community.libre.space/t/spacex-f9-transporter-11-rideshare-vsfb-slc… (ANS thanks LibreSpace and the ORESAT team for the above information) + Three AMSAT GridMaster Awards were awarded over the past week: #67 was awarded to Endaf, N6UTC, #68 was awarded to Raymond, KN2K, and #69 was awarded to Steven, KC1MMC. Congratulations to both. Additionally, two Reverse VUCC Awards were issued. #15 was awarded to Sean, KX9X, with 103 grids and #16 was issued to Randy, ND0C, with 109 grids. Congratulations to all the new award recipients!

FS: Tidradio TD-H8 10 watt dualband HT
by JOHN GEIGER 17 Aug '24

17 Aug '24

If you are looking for a little more power for your portable satellite operations, here you go: I have for sale a like new Tidradio TD-H8 2m/70cm 10 watt HT. Miklor and other reviews have measured this HT model at 10 watts on both bands, so it is putting out claimed power. It comes with all the standard accessories, and has a color screen and a battery (2500mah) which can be charged using a USB-C cable in addition to the drop in charger. It also has a nice dualband antenna which I have used to make a couple of FM satellite QSOs with. This HT has bluetooth capability for programming, so you don't need a programming cable. It uses ODMASTER software so you can program it using your phone. That is a nice feature to have! It currently has the satellite frequencies programmed into memory. It comes with the box, manual, HT, battery and antenna, the drop in charger, and a USB-C cable with wall-wart. I am asking $55 shipped and can take paypal/check/MO. 73 John AF5CC Sent using {0}

ARISS News Release No. 24-47
by David H Jordan 15 Aug '24

15 Aug '24

*ARISS News Release No.24-47* *Dave Jordan, AA4KN * *ARISS PR* *aa4kn(a)amsat.org <aa4kn(a)amsat.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Students at * *Tuskegee Airmen Inc. National Convention, Arlington, Virginia* August 15, 2024—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an astronaut aboard the International Space Station (ISS) and students at the Tuskegee Airmen Inc. National Convention located in Arlington, VA. ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. Tuskegee Airmen Inc. (TAI) has 50 chapters across the United States with the common goal of assuring the legacy of the Tuskegee Airmen of WWII is used to inspire and motivate young people in the career fields of aviation and aerospace. The annual TAI National Convention (in the Washington DC area this year) affords high school students the opportunity to interact with aviation and aerospace professionals and engage in STEM related hands-on activities, including use of the ARISS’ SPARKI SDR (Software Defined Radio) kit, learning about the technology that makes student conversations with the astronauts on the ISS possible. This ARISS contact is to be a part of the TAI National Convention Youth Day with those high school student attendees participating in the contact. An ARISS contact during the height of the convention, including attendees from all over the U.S., would be an experience that will spread far beyond the confines of our conference, as all take home first-hand exposure and expanded understanding of the vast possibilities of science in their lives. Post convention, the information on the ISS contact, SPARKI and ARISS programs will be shared with all chapters, and thus hundreds of communities across the country. This will be a telebridge Contact via Amateur Radio allowing students to ask their questions of astronaut Jeanette Epps, amateur radio call sign KF5QNU. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the telebridge station. The ARISS amateur radio ground station (telebridge station) for this contact is in Greenbelt, Maryland, U.S. The amateur radio volunteer team at the ground station will use the callsign K6DUE, to establish and maintain the ISS connection. The ARISS radio contact is scheduled for August 17, 2024 at 1:34:57 pm EDT (Arlington, VA) (17:34:57 UTC, 12:34 pm CDT, 11:34 am MDT, 10:34 am PDT). *_______________________________* As time allows, students will ask these questions: 1. What was it like launching up into space? 2. What’s the biggest difference between a day on Earth compared to in space? 3. How do you navigate being able to float when there’s no gravity and do you ever get motion sickness? 4. What kind of experiments are you working on and why do them in space? 5. What do you do for fun during your downtime in space? 6. How and when do you sleep? 7. Is being in space going the way you thought it would go or have you had surprises? 8. If you got to go into space again, what would you change to improve your experience? 9. If you could bring one thing from Earth into space that you don’t have now, what would it be? 10. How long was the training phase to be able to go into space? 11. If you had to, how would you describe space in one word? 12. What’s the first thing you’ll do when you get back to Earth? 13. How has this experience impacted your life? Did it change your views of the world? 14. Why did you want to travel to space, and did you think it would be scary? 15. What’s the hardest thing about being on the space station and why? 16. What’s the easiest thing about being on the space station and why? 17. What do you miss on Earth most? 18. What is the coolest thing about being in space? 19. Do you to talk with your family every day? 20. Do you ever feel claustrophobic? 21. How do you tell time in space since there’s no sunrise or sunset? 22. Do you ever have any real privacy? *About ARISS:* Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS.

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

FUNcube Data Warehouse Outages
by David Johnson 15 Aug '24

15 Aug '24

Hi Our hosting provider has told us that they will be migrating our services to a new virtual machine on the 1st of September. Unfortunately the versions of the MySQL database server and Java runtime available on the new instance are not compatible with the current application implementation. Therefore I have to rebuild the development tool chain and migrate the application to suit the new instance. The work is underway but may take us into early September. We do know that database table migration works as we have already done a test of migrating the several GB of database between machines. If we do have any outage, the dashboards will upload when they detect the new instance is alive. 73 Dave, G4DPZ FUNcube Team Member Hon. Sec. AMSAT-UK

Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

FS: Yaesu FT8800 full duplex 2m/70cm transceiver
by JOHN GEIGER 14 Aug '24

14 Aug '24

I have for sale a Yaesu FT8800 2m/70cm transceiver which does 50 watts on 2m and 35 watts on 70cm. It does dual receive and full duplex which makes it great for FM satellites. With the dual receive you can listen to 2 frequencies at once, even in the same band. It also has tone encode, tone decode, and DCS encode/decode, and will do crossband repeat. The 6 hypermemories each have their own dedicated button and they really make storing satellite frequencies or two different repeaters very easy. The case has some residue on it in a couple of places, and there are some scratches. It shows wear but works great on transmit and receive. It is missing the upper right knob, but you can still turn the encoder shaft just fine, and knobs are cheap on ebay. The right side volume/squelch encoder might need to be replaced. It will turn on and off but you have to push a little hard on the encode knob, and the volume and squelch turn together as it was bent and then repaired. There was a smoke odor to the radio when I got it but I have since deodorized it. It comes with a new hand mic, power cord, and mobile mounting bracket. I am asking $150 shipped and can take paypal/check/MO. 73 John AF5CC Sent using {0}

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

Hi John, Science mode is enabled when we send image data. You can see that in FoxTelem because you will receive data on the MESAT Science tab. If that data is valid image packets then an image is built on the Multispectral Camera Tab. Each image captured is actually 4 images or channels and will become 4 separate images in FoxTelem. Each taken with a different filter. A copy of the images is also saved as a bitmap in the FoxTelem data directory in an images sub folder. There is a slightly updated version of FoxTelem on my website, in the development downloads, which indicates how many bytes you have received for each block in the image. Download version 1.12z5 (not version 1.13 which does not have this feature yet): https://www.g0kla.com/foxtelem/ With that said, nothing in space is easy and so far we have only retrieved some test data that was loaded before launch, from Image 1 Channel 0. But we are optimistic that image data is coming. Our current test is over and the spacecraft is back in SAFE mode where it will rest for about 3 days. We hope to start some science operations again after that. If you are curious about the data, then you can always download the full set collected by everyone from the server. The FoxTelem manual explains how to setup a second copy of FoxTelem with a different data folder. You can then pull the server data down into that copy with File > Fetch Server Data. There you will see the partially downloaded test data. If you are good at sleuthing through data you can see the magnetorquers activate when we sent commands to stabilize the spacecraft for image capture.

The module was programmed to transmit FT-8, which is, as far as the project managers know, the first time that this modulation has been used from space, as well as SSTV. Although its reception seemed impossible, a station located in Delft, the Netherlands, confirmed the reception and decoding of FT-8, as well as the reception of SSTV in orbits 3 and 4 that the stage carried out over Europe. [cid:[email protected]] The station, belonging to the Von Storch Engineering company, has provided the IQ files of the recordings for analysis by AMSAT-EA. Although the stage was expected to fall into the sea, this did not happen and the GENESIS-A module remains in orbit with the stage. ESA was asked about the availability of power in the launcher stage and about the possibility of restarting the module, but the battery pack that powered YPSAT and the GENESIS-A module was completely depleted, so there is no real possibility of restarting it.

CubeSats are a class of small spacecraft called nanosatellites. The initiative provides space access to U.S. educational institutions, certain non-profit organizations, and informal educational institutions such as museums and science centers, as well as NASA centers focused on workforce development, including the agency’s Jet Propulsion Laboratory in southern California. It also encourages participation by minority serving institutions. “Working with CubeSats is a way to get students interested in launching a career in the space industry,” said Jeanie Hall, CSLI program executive at NASA Headquarters in Washington. “NASA reviews applications for CubeSat missions every year and selects projects with an educational component that also can benefit the agency in better understanding education, science, exploration, and technology.” Applicants must submit proposals by 5 p.m. EST, Nov. 15. NASA expects to make selections by March 14, 2025, for flight opportunities in 2026-2029, although selection does not guarantee a launch opportunity. Applicants are responsible for funding the development of the small satellites. Selected CubeSats get assigned a launch and deployment directly from a rocket or to low Earth orbit from the International Space Station. Once accepted, NASA mission managers act as advisors to the CubeSat team, ensuring technical, safety, and regulatory requirements are satisfied before launch. Those selected will strengthen their skills in hardware design and development and build knowledge in operating the CubeSats. Eight CubeSat missions recently shared a ride to space on Firefly Aerospace’s Alpha rocket that launched on July 3 from Vandenberg Space Force Base in California. One mission is CatSat, built by students at the University of Arizona, which is testing a deployable antenna attached to a Mylar balloon. Another is KUbeSat-1, built by the University of Kansas, is testing a new method of measuring the cosmic rays that hit the Earth. This launch also was notable for two CSLI ‘first’ milestones. The KUbeSat-1 and another called MESAT-1 were the first CSLI missions from the states of Kansas and Maine respectively. Four CubeSats also went to the space station as cargo in a SpaceX Dragon capsule on March 21 aboard a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida as part of the agency’s SpaceX 30th commercial resupply mission. Once aboard the space station, astronauts deployed the small missions into various orbits to demonstrate and mature technologies meant to improve solar power generation, detect gamma ray bursts, determine crop water usage, and measure root-zone soil and snowpack moisture levels. CubeSats are a class of spacecraft sized in multiples of a standardized unit called a “U.” A 1-Unit (1U) CubeSat is about 10 x 10 x 11 cm in size (3.9 x 3.9 x 4.5 inches). They are small enough to fit in the palm of your hand and can be stacked together to form a slightly larger, more capable spacecraft. A 3U CubeSat is three times the size of a 1U, a 6U is six times the size. NASA has selected CubeSat missions from 45 states, Washington, and Puerto Rico, and launched about 160 CubeSats since inception. The CubeSat Launch Initiative is managed by NASA’s Launch Services Program based at NASA’s Kennedy Space Center in Florida.

NASA public affairs officer Rob Margetta said there was no immediate threat to the International Space Station. Satellite monitoring company LeoLabs estimated there were at least 700 fragments created by the rocket’s break-up. While there’s no immediate danger, it’s possible that the fragments could eventually descend to where the space station and SpaceX’s Starlink satellites are located.

Please copy! MESAT1 in HEALTH mode, camera testing on Saturday 8/10/24 1146utc and 1316utc
by Mark Hammond 10 Aug '24

10 Aug '24

Hi All, We are in the midst of a testing session with the University of Maine's first satellite, MESAT1. We have just (8/10/24 0108utc) sent a stored test image to ground stations. MESAT1 remains in HEALTH mode, so telemetry is on all the time for maybe the next 12-24 hours. We can especially use telemetry frames to be collected tomorrow during the 1146utc and 1316utc morning passes. We are attempting to take and download its first photo. All telemetry from all around the globe is welcome and very helpful. We will likely decrease the telemetry power for an orbit, but increase again to download the image. Grab what you can in FoxTelem, and upload to the server all of your frames! https://www.g0kla.com/foxtelem/ Thanks for your help! It's been great thus far. 73, -- Mark L. Hammond [N8MH] AMSAT Director and Command Station

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

(***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-08-05 20:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** The ARISS webpage is at https://www.ariss.org/ Note that there are links to other ARISS websites from this site.

(***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-08-05 20:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

GENESIS-A module was received from The Netherlands
by Félix Páez 05 Aug '24

05 Aug '24

Dear all, AMSAT EA's GENESIS-A module, attached to the upper stage of the Ariane-6 launcher, was put into orbit with the inaugural launch of the said rocket on July 9th from French Guiana. The module was programmed to transmit FT-8, which is, as far as we know, the first time that this modulation has been used from space, as well as SSTV. Although its reception seemed impossible, a station located in Delft, the Netherlands, confirmed the reception and decoding of FT-8, as well as the reception of SSTV in orbits 3 and 4 that the stage carried out over Europe. https://x.com/vonstorcheng/status/1813609538987463069 The station, belonging to the company Von Storch Engineering, has provided the IQ files of the recordings for analysis by AMSAT-EA. Although the stage was expected to fall into the sea, this did not happen and the GENESIS-A module remains in orbit with the stage. ESA was asked about the availability of power in the launcher stage and about the possibility of restarting the module, but the battery pack that powered YPSAT and the GENESIS-A module was completely depleted, so there is no real possibility of restarting it. 73 Félix EA4GQS - AMSAT EA

ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. *Please send any amateur satellite news or reports to: ans-editor [at] amsat.org <http://amsat.org>* You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-217 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2024 Aug 4 ROBUSTA-3A in Orbit When the long-delayed inaugural launch of the European Space Agency’s (ESA’s) new Ariane 6 rocket finally occurred on July 7, it suffered an upper stage failure that left some payloads in the wrong orbits. Fortunately, before the anomaly developed, the Ariane 6 successfully deployed ROBUSTA-3A, a satellite with an amateur radio payload. The target was a 580 km circular orbit with an inclination of 96 degrees. ROBUSTA-3A (a.k.a. “Méditerranée”) is a 3U cubesat, designed and built by students and faculty of Université de Montpellier in southern France. Over a decade in development, involving around 300 students from the University of Montpellier and all over the world, ROBUSTA-3A will be its seventh satellite developed entirely in-house, having learned much from the development and launch of smaller ROBUSTA-1U satellites. The project has offered hands-on training, engineering and scientific experience to the next generation of space engineers and researchers. *The Robusta 3A satellite is 3U, three CubeSat units. (Photo: Van Allen Foundation)* The satellite’s primary mission is weather observation, specifically to track “Cevenol events.” These are intense storms and incredibly heavy rains that cause extensive flooding, often in the form of flash floods, that hit the plains and the foothills of southern France. Once considered “100-year storms,” they have been occurring with greater frequency due to global climate change. Most of the weather data is downlinked on a commercial S-band microwave frequency. “If the data we will be collecting improves the geographic and temporal accuracy of weather forecasts for cévenol events, it would help authorities give early warning to the population and allow rescue services to better target the areas at risk,” explains Romain Briand, assembly integration and testing manager at the University Space Center of Montpellier. *Robusta-3A under development by Centre Spatial Universitaire de Montpellier (CSUM)* However, ROBUSTA-3A aims to do even more than chart water vapour from space. The satellite carries an experimental Attitude Determination and Control System (ADCS) that will seek to optimize solar panel exposure and correctly aim sensors and microwave downlink antennas. Using a set of Sun sensors, magnetometers, and reaction wheels in a pyramidal configuration, the system should provide precise attitude control, especially during orbital maneuvers. The satellite will also employ a cold gas thruster propulsion system which operates with solid iodine as propellant. This system will demonstrate orbit maintenance, phasing, and lifetime extension of small satellite missions, and could also help with end-of-life decommissioning and debris mitigation. As an extra mission, the CubeSat will test how computer memory from chip manufacturer 3D PLUS withstands the radiation of space. This French company specialises in highly-reliable electronic components and their computer memory recently landed on the Moon as part of the India’s Chandrayaan-3 lander. Finally, ROBUSTA-3A also carries a 9k6 GMSK AX.25 store-and-forward digital system with a UHF transmitter output of up to three watts — a very powerful downlink! As the satellite is sill in commissioning, operating protocols and uplink frequency have not yet been released. However, amateurs should expect something similar to the FalconSAT-3 store-and-forward system that was popular until that satellite deorbited in January of 2023. ROBUSTA-3A is currently transmitting short telemetry bursts on its International Amateur Radio Union (IARU) coordinated downlink frequency of 436.750 MHz.

A total of 421 messages were digipeated.” The Bayerische Julius-Maximilians-Universität Würzburg’s SONATE (SOlutus NAno satelliTE) satellite is a technology demonstration mission for highly autonomous payloads and artificial intelligence in the 6U CubeSat class. As part of the SONATE-2 mission, novel hardware and software technologies of artificial intelligence (AI) are to be verified in miniaturized format in earth orbit. By using such AI technologies, the satellite can independently analyze the environment and start autonomous recordings. Deep learning plays a special role as a versatile image processing tool. In addition to the classification of targets already known at the start of the mission, the payload should also have the option of on-board training for the detection of anomalies as previously unknown objects or phenomena. *SONATE-2 mission patch (JMU artwork)* The operation of an amateur radio payload is important to the educational mission of SONATE-2. The development and operation of the satellite is used for the education of students of the university. In cooperation with the DLR School Lab in Neustrelitz, Germany, it is planned to use the amateur radio payload for the education of high school students. The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the course of several student projects. For SONATE-2 additional student projects extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon. On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, as thesis authors or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite. The German Aerospace Center (DLR) offers a School Lab for high school students at the location of the external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission. Besides the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload. *SONATE-2 Test Model, October 2023 (Photo: JMU)* According to Kayal, not many similar projects are currently being undertaken. “Let’s assume that a small satellite is to investigate a new asteroid in the solar system in the future. It cannot be trained for this task on the ground, because the object of investigation is largely unknown. There is no training data, so the measurements and recordings can’t be made on the ground,” Kayal added. Transmitting this data to Earth for initial processing and subsequently training the AI via remote control would result in significant time delays for missions located at a considerable distance from Earth. Opting for a heightened level of autonomy with direct on-board AI support would greatly enhance the mission’s efficiency. This approach would expedite the detection of intriguing objects and phenomena on the asteroid, considerably reducing the time required for their identification. To facilitate this, four on-board cameras capture the essential imagery required for training the AI. Initially, the AI acquires knowledge of conventional geometric patterns on Earth’s surface, among other things, which subsequently empowers it to autonomously identify anomalies. *A model of the SONATE-2 nanosatellite, here artistically depicted in orbit. (Image: Hakan Kayal / Universität Würzburg)* In addition to these AI experiments, SONATE-2 carries a suite of other small satellite technologies that are ready for in-orbit testing. These technologies include an automated lightning detection and recording system, as well as an electric propulsion system developed in collaboration with the University of Stuttgart. Kayal added, “In terms of complexity, SONATE-2 is unparalleled among nanosatellites.” SONATE-2 was one of a cluster of satellites launched on a SpaceX Falcon-9 flight on March 5, 2024.

The venue was the Police Training Center at Rajkot Headquarter. It was a highly informative 3 hours session from 10:00 AM to 1:00 PM. Regional Coordinator of AMSAT-INDIA & The Amateur Radio Society of India, Mr. Rajesh Vagadia, VU2EXP, gave insight into various Radio Communication protocols, types of modulation, modes & various applications used in Amateur Radio & Police department. *Rajesh Vagadia, VU2EXP (hamphotos.com <http://hamphotos.com>)* As this workshop was targeted for 25 technical wireless officers & radio operators, we focused on the radio communication enhancing methods, utilizing various techniques, using different antennas for specific applications and diagnosis of wireless setup with various measuring instruments incl. SWR/Power Meter, NanoVNA/Antenna Analyzer. We extended a handful of maintenance tips for Radio, Antenna, Feed line & repeaters to optimize radio communications. We also gave an overview of Ham Radio & its various events, Understanding of Digital Communication, Satellite Communication, Features of newer Digital protocol incl. DMR, D-STAR & Fusion. There was good interaction with participants, lots of doubt & queries were cleared satisfactorily. Good number of radio stuff was displayed incl. HTs, VHF Base Radio, IC-705 SDR HF Radio, RTL SDR Dongle, Antenna Tuner, CAT Control, Soundcard Interface, Morse Key, CW Paddle & Keyer, CubeSat model, Balun, LNA, SWR/Power meter, NanoVNA, Dummy load, PSU, Feed lines, EFHW Antenna, Telescopic Antenna, Connectors, Adaptors, ARISS Awards, QSL Cards etc., which helped participants to view, discuss & understand our entire stuff better. We always give practical demos, but, here in the audience was a heavy user of CW & RT from the police dept. We didn’t give a demo of that kind hi..hi.., but surely gave demos of Digital Communication – sending text messages between two VHF Setup and a second demo of sending SSTV Images between two local vhf stations! For the audience it was interesting to learn how we ham convert simple ASCII codes to corresponding audio frequencies (for Digital Communication) and RGB pixel values of Image to Slow Scan Television format to transmit & receive ‘IMAGES’ via our standard radios! That’s why we proudly call Ham Radio the oldest Social Media! It was a nice & fruitful workshop overall. I am thankful to Commissioner of Police Rajkot Shri Brajesh Kumar Jha Sir for approval of this workshop and Shri S K Jadeja Sir (PI Wireless) for nicely coordinating this workshop. I am thankful to our AMSAT-INDIA & ARSI (The Amateur Radio Society of India) for their great support and guidance to make this workshop highly successful. We wish Rajkot Gujarat Police will utilize the gained knowledge & implement into the system for better productivity!

Over the past 15 years, small satellites have revolutionized how things are done in space. Built quickly from cheap, off-the-shelf components, and small enough to hitch an affordable ride to orbit on the back of bigger missions, these devices and the young, agile New Space companies behind them taught the old-school space industry a few lessons. But New Space is coming of age and the firms behind the small satellite revolution must live up to expectations less favorable to their trade-mark experimental ethos. The lowest cost and shortest time to orbit may no longer be the technology’s biggest draw as users want maximum return on investment and require granted reliability. The firms behind the disruptive tech, however, have grown up together with their market share and are tapping into emerging innovation, looking to unleash a whole load of new applications in the coming years. The Evolution of the Smallsat *Members of the ABMA satellite team (with Gen. Medaris and Dr. von Braun seated in center) with a model of the Explorer 1 satellite. (Photo, U.S. Army)* Satellites started small. The first U.S. satellite, Explorer 1 — launched in 1958 — weighed only 14 kilograms. But the technology, prized for opening a whole new perspective on our planet, quickly bulked up, enabled by the increasing lifting powers of fast-evolving rockets. Soon, complex satellites the size of a school bus took over, observing the planet from above, broadcasting TV signals across continents and sensing the environment around them. It was only in the mid-1980s that researchers renewed their interest in smaller satellites with masses of tens to a couple of hundred kilograms. The true small sat revolution, however, began in 1999, with the invention of a cubesat. Based on standardized satellite units of 10 by 10 by 10 centimeters in size, cubesats opened space to anyone with enough technical skill to assemble and operate them. Soon, university teams from all over the world began launching their own experimental spacecraft to provide their students with hands-on space tech experience. By 2014, San Francisco-based Planet Labs launched its first commercial constellation of 28 three-unit (3U) Earth-observing cubesats called Doves. More than 120 Doves are in orbit today, capturing an image of each place on Earth more than once a day. Other companies followed suit. As of today, cubesats have made it to orbit around Mars and the Moon and observed the impact of NASA’s Double Asteroid Redirection Test (DART) into the asteroid Didymos in 2022 in real-time. *The Axelspace Pyxis mission launched in March of this year. (Photo: Axelspace)* Larger small satellite platforms — up to 500 kg in mass — have also grown in popularity. In fact, these larger small satellites today dominate space around Earth thanks to SpaceX’s constellation of Starlink internet-beaming satellites. Consulting firm Novaspace predicts that 26,104 small satellites — including minisatellites of 100 to 500 kg in mass, microsatellites between 10 and 100 kg and nanosatellites as light as 1 to 10 kg — will launch in the next decade. And although the smallsat revolution is already behind us, new technologies are emerging that promise to supercharge the sector in the coming years. Via Satellite spoke with a number of experts in the field about what the smallsat of the future will look like.

As always, launches are subject to a wide variety of variables, and space agencies are not always 100% forthcoming about their activities. So while you may not want to mark the calendar just yet, hopeful signs are pointing toward a launch in the coming months. *Artist’s sketch of ASRTU-1* ASRTU-1 is a 12U Cubesat mission designed by Russian and Chinese university students for education and amateur radio. Harbin Institute of Technology has successfully developed several amateur radio satellites, including LilacSat-2 (CAS-3H), LilacSat-1 (LO-90), DSLWP-A (LO-93) and DSLWP-B (LO-94). The partner institution is Bauman Moscow State Technical University, which constructed two satellites, Baumanets-1 in 2006 and Baumanets-2 in 2017, both of which unfortunately failed to reach orbit due to launch failures unrelated to the satellite payloads. The amateur radio station onboard ASRTU-1 will provide FM and telecommand uplinks, as well as FM, telemetry, and digital image downlinks. A new SDR based transceiver was developed to provide communication and experimental resources to radio amateurs, including a V/U FM transponder, a UHF telemetry downlink, and a 10.5G image downlink. The repeater uplink will be on 145.875 MHz FM using a 67 Hz CTCSS (PL) tone. Downlink will be on 435.400 MHz FM. The telemetry beacon will be on 436.210 MHz using 9k6 bps BPSK. In addition to the FM repeater, the satellite will also provide an open telecommand system to allow radio amateurs to send commands to control the satellite to take and download images. X Band image downloads using 1 Mbps/10mbps QSPK will downlink on 10.460 GHz. ASRTU-1 has been scheduled for a Roscosmos launch from Vostochny Cosmodrome, Asiatic Russia, in Q4 2024 into a 530 km Sun-synchronous Orbit (SSO). Downlinks and the repeater uplink have been coordinated by the International Amateur Radio Union (IARU).

Fortunately, before the anomaly developed, the Ariane 6 successfully deployed ROBUSTA-3A, a satellite with an amateur radio payload. The target was a 580 km circular orbit with an inclination of 96 degrees. ROBUSTA-3A (a.k.a. “Méditerranée”) is a 3U cubesat, designed and built by students and faculty of Université de Montpellier in southern France. Over a decade in development, involving around 300 students from the University of Montpellier and all over the world, ROBUSTA-3A will be its seventh satellite developed entirely in-house, having learned much from the development and launch of smaller ROBUSTA-1U satellites. The project has offered hands-on training, engineering and scientific experience to the next generation of space engineers and researchers. The Robusta 3A satellite is 3U, three CubeSat units. (Photo: Van Allen Foundation) The satellite’s primary mission is weather observation, specifically to track “Cevenol events.” These are intense storms and incredibly heavy rains that cause extensive flooding, often in the form of flash floods, that hit the plains and the foothills of southern France. Once considered “100-year storms,” they have been occurring with greater frequency due to global climate change. Most of the weather data is downlinked on a commercial S-band microwave frequency. “If the data we will be collecting improves the geographic and temporal accuracy of weather forecasts for cévenol events, it would help authorities give early warning to the population and allow rescue services to better target the areas at risk,” explains Romain Briand, assembly integration and testing manager at the University Space Center of Montpellier. Robusta-3A under development by Centre Spatial Universitaire de Montpellier (CSUM) However, ROBUSTA-3A aims to do even more than chart water vapour from space. The satellite carries an experimental Attitude Determination and Control System (ADCS) that will seek to optimize solar panel exposure and correctly aim sensors and microwave downlink antennas. Using a set of Sun sensors, magnetometers, and reaction wheels in a pyramidal configuration, the system should provide precise attitude control, especially during orbital maneuvers. The satellite will also employ a cold gas thruster propulsion system which operates with solid iodine as propellant. This system will demonstrate orbit maintenance, phasing, and lifetime extension of small satellite missions, and could also help with end-of-life decommissioning and debris mitigation. As an extra mission, the CubeSat will test how computer memory from chip manufacturer 3D PLUS withstands the radiation of space. This French company specialises in highly-reliable electronic components and their computer memory recently landed on the Moon as part of the India’s Chandrayaan-3 lander. Finally, ROBUSTA-3A also carries a 9k6 GMSK AX.25 store-and-forward digital system with a UHF transmitter output of up to three watts — a very powerful downlink! As the satellite is sill in commissioning, operating protocols and uplink frequency have not yet been released. However, amateurs should expect something similar to the FalconSAT-3 store-and-forward system that was popular until that satellite deorbited in January of 2023. ROBUSTA-3A is currently transmitting short telemetry bursts on its International Amateur Radio Union (IARU) coordinated downlink frequency of 436.750 MHz.

Help Support GOLF and Fox Plus Join the AMSAT President’s Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ SONATE-2 APRS Digipeater in Operation Professor Hakan Kayal from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany posted on X this past week, “Thanks to everyone using SONATE-2’s APRS digipeater over the weekend. A total of 421 messages were digipeated.” The Bayerische Julius-Maximilians-Universität Würzburg’s SONATE (SOlutus NAno satelliTE) satellite is a technology demonstration mission for highly autonomous payloads and artificial intelligence in the 6U CubeSat class. As part of the SONATE-2 mission, novel hardware and software technologies of artificial intelligence (AI) are to be verified in miniaturized format in earth orbit. By using such AI technologies, the satellite can independently analyze the environment and start autonomous recordings. Deep learning plays a special role as a versatile image processing tool. In addition to the classification of targets already known at the start of the mission, the payload should also have the option of on-board training for the detection of anomalies as previously unknown objects or phenomena. SONATE-2 mission patch (JMU artwork) The operation of an amateur radio payload is important to the educational mission of SONATE-2. The development and operation of the satellite is used for the education of students of the university. In cooperation with the DLR School Lab in Neustrelitz, Germany, it is planned to use the amateur radio payload for the education of high school students. The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the course of several student projects. For SONATE-2 additional student projects extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon. On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, as thesis authors or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite. The German Aerospace Center (DLR) offers a School Lab for high school students at the location of the external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission. Besides the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload. SONATE-2 Test Model, October 2023 (Photo: JMU) According to Kayal, not many similar projects are currently being undertaken. “Let’s assume that a small satellite is to investigate a new asteroid in the solar system in the future. It cannot be trained for this task on the ground, because the object of investigation is largely unknown. There is no training data, so the measurements and recordings can’t be made on the ground,” Kayal added. Transmitting this data to Earth for initial processing and subsequently training the AI via remote control would result in significant time delays for missions located at a considerable distance from Earth. Opting for a heightened level of autonomy with direct on-board AI support would greatly enhance the mission’s efficiency. This approach would expedite the detection of intriguing objects and phenomena on the asteroid, considerably reducing the time required for their identification. To facilitate this, four on-board cameras capture the essential imagery required for training the AI. Initially, the AI acquires knowledge of conventional geometric patterns on Earth’s surface, among other things, which subsequently empowers it to autonomously identify anomalies. A model of the SONATE-2 nanosatellite, here artistically depicted in orbit. (Image: Hakan Kayal / Universität Würzburg) In addition to these AI experiments, SONATE-2 carries a suite of other small satellite technologies that are ready for in-orbit testing. These technologies include an automated lightning detection and recording system, as well as an electric propulsion system developed in collaboration with the University of Stuttgart. Kayal added, “In terms of complexity, SONATE-2 is unparalleled among nanosatellites.” SONATE-2 was one of a cluster of satellites launched on a SpaceX Falcon-9 flight on March 5, 2024.

The venue was the Police Training Center at Rajkot Headquarter. It was a highly informative 3 hours session from 10:00 AM to 1:00 PM. Regional Coordinator of AMSAT-INDIA & The Amateur Radio Society of India, Mr. Rajesh Vagadia, VU2EXP, gave insight into various Radio Communication protocols, types of modulation, modes & various applications used in Amateur Radio & Police department. Rajesh Vagadia, VU2EXP (hamphotos.com) As this workshop was targeted for 25 technical wireless officers & radio operators, we focused on the radio communication enhancing methods, utilizing various techniques, using different antennas for specific applications and diagnosis of wireless setup with various measuring instruments incl. SWR/Power Meter, NanoVNA/Antenna Analyzer. We extended a handful of maintenance tips for Radio, Antenna, Feed line & repeaters to optimize radio communications. We also gave an overview of Ham Radio & its various events, Understanding of Digital Communication, Satellite Communication, Features of newer Digital protocol incl. DMR, D-STAR & Fusion. There was good interaction with participants, lots of doubt & queries were cleared satisfactorily. Good number of radio stuff was displayed incl. HTs, VHF Base Radio, IC-705 SDR HF Radio, RTL SDR Dongle, Antenna Tuner, CAT Control, Soundcard Interface, Morse Key, CW Paddle & Keyer, CubeSat model, Balun, LNA, SWR/Power meter, NanoVNA, Dummy load, PSU, Feed lines, EFHW Antenna, Telescopic Antenna, Connectors, Adaptors, ARISS Awards, QSL Cards etc., which helped participants to view, discuss & understand our entire stuff better. We always give practical demos, but, here in the audience was a heavy user of CW & RT from the police dept. We didn’t give a demo of that kind hi..hi.., but surely gave demos of Digital Communication – sending text messages between two VHF Setup and a second demo of sending SSTV Images between two local vhf stations! For the audience it was interesting to learn how we ham convert simple ASCII codes to corresponding audio frequencies (for Digital Communication) and RGB pixel values of Image to Slow Scan Television format to transmit & receive ‘IMAGES’ via our standard radios! That’s why we proudly call Ham Radio the oldest Social Media! It was a nice & fruitful workshop overall. I am thankful to Commissioner of Police Rajkot Shri Brajesh Kumar Jha Sir for approval of this workshop and Shri S K Jadeja Sir (PI Wireless) for nicely coordinating this workshop. I am thankful to our AMSAT-INDIA & ARSI (The Amateur Radio Society of India) for their great support and guidance to make this workshop highly successful. We wish Rajkot Gujarat Police will utilize the gained knowledge & implement into the system for better productivity!

Over the past 15 years, small satellites have revolutionized how things are done in space. Built quickly from cheap, off-the-shelf components, and small enough to hitch an affordable ride to orbit on the back of bigger missions, these devices and the young, agile New Space companies behind them taught the old-school space industry a few lessons. But New Space is coming of age and the firms behind the small satellite revolution must live up to expectations less favorable to their trade-mark experimental ethos. The lowest cost and shortest time to orbit may no longer be the technology’s biggest draw as users want maximum return on investment and require granted reliability. The firms behind the disruptive tech, however, have grown up together with their market share and are tapping into emerging innovation, looking to unleash a whole load of new applications in the coming years. The Evolution of the Smallsat Members of the ABMA satellite team (with Gen. Medaris and Dr. von Braun seated in center) with a model of the Explorer 1 satellite. (Photo, U.S. Army) Satellites started small. The first U.S. satellite, Explorer 1 — launched in 1958 — weighed only 14 kilograms. But the technology, prized for opening a whole new perspective on our planet, quickly bulked up, enabled by the increasing lifting powers of fast-evolving rockets. Soon, complex satellites the size of a school bus took over, observing the planet from above, broadcasting TV signals across continents and sensing the environment around them. It was only in the mid-1980s that researchers renewed their interest in smaller satellites with masses of tens to a couple of hundred kilograms. The true small sat revolution, however, began in 1999, with the invention of a cubesat. Based on standardized satellite units of 10 by 10 by 10 centimeters in size, cubesats opened space to anyone with enough technical skill to assemble and operate them. Soon, university teams from all over the world began launching their own experimental spacecraft to provide their students with hands-on space tech experience. By 2014, San Francisco-based Planet Labs launched its first commercial constellation of 28 three-unit (3U) Earth-observing cubesats called Doves. More than 120 Doves are in orbit today, capturing an image of each place on Earth more than once a day. Other companies followed suit. As of today, cubesats have made it to orbit around Mars and the Moon and observed the impact of NASA’s Double Asteroid Redirection Test (DART) into the asteroid Didymos in 2022 in real-time. The Axelspace Pyxis mission launched in March of this year. (Photo: Axelspace) Larger small satellite platforms — up to 500 kg in mass — have also grown in popularity. In fact, these larger small satellites today dominate space around Earth thanks to SpaceX’s constellation of Starlink internet-beaming satellites. Consulting firm Novaspace predicts that 26,104 small satellites — including minisatellites of 100 to 500 kg in mass, microsatellites between 10 and 100 kg and nanosatellites as light as 1 to 10 kg — will launch in the next decade. And although the smallsat revolution is already behind us, new technologies are emerging that promise to supercharge the sector in the coming years. Via Satellite spoke with a number of experts in the field about what the smallsat of the future will look like.

As always, launches are subject to a wide variety of variables, and space agencies are not always 100% forthcoming about their activities. So while you may not want to mark the calendar just yet, hopeful signs are pointing toward a launch in the coming months. Artist’s sketch of ASRTU-1 ASRTU-1 is a 12U Cubesat mission designed by Russian and Chinese university students for education and amateur radio. Harbin Institute of Technology has successfully developed several amateur radio satellites, including LilacSat-2 (CAS-3H), LilacSat-1 (LO-90), DSLWP-A (LO-93) and DSLWP-B (LO-94). The partner institution is Bauman Moscow State Technical University, which constructed two satellites, Baumanets-1 in 2006 and Baumanets-2 in 2017, both of which unfortunately failed to reach orbit due to launch failures unrelated to the satellite payloads. The amateur radio station onboard ASRTU-1 will provide FM and telecommand uplinks, as well as FM, telemetry, and digital image downlinks. A new SDR based transceiver was developed to provide communication and experimental resources to radio amateurs, including a V/U FM transponder, a UHF telemetry downlink, and a 10.5G image downlink. The repeater uplink will be on 145.875 MHz FM using a 67 Hz CTCSS (PL) tone. Downlink will be on 435.400 MHz FM. The telemetry beacon will be on 436.210 MHz using 9k6 bps BPSK. In addition to the FM repeater, the satellite will also provide an open telecommand system to allow radio amateurs to send commands to control the satellite to take and download images. X Band image downloads using 1 Mbps/10mbps QSPK will downlink on 10.460 GHz. ASRTU-1 has been scheduled for a Roscosmos launch from Vostochny Cosmodrome, Asiatic Russia, in Q4 2024 into a 530 km Sun-synchronous Orbit (SSO). Downlinks and the repeater uplink have been coordinated by the International Amateur Radio Union (IARU).

Thompson, VE2TCP / G0KLA / AC2CZ, for the above information.) + SpaceX is now targeting mid- to late August for the launch of Polaris Dawn, a mission funded by billionaire entrepreneur Jared Isaacman. The upcoming flight, which will employ SpaceX’s Crew Dragon spacecraft and Falcon 9 rocket, had been slated to lift off no earlier than July 31. SpaceX announced the delay today (July 26), during a press conference focusing on the company’s upcoming Crew-9 astronaut mission to the International Space Station (ISS) for NASA. The NASA mission will include Zena Cardman, KJ5CMN, Nick Hague, KG5TMV, Stephanie Wilson, KD5DZE, and Aleksandr Gorbunov, Roscosmos. Crew-9 will launch no earlier than Aug. 18, and Polaris Dawn will fly sometime after that, the company said. The Polaris Dawn mission is scheduled to include the first-ever private spacewalk. (ANS thanks Space.com for the above information.) + The U.S. military is installing modular state-of-the-art satellite jammers capable of disrupting Russian or Chinese communications, should the need arise. Even though the hardware is ground-based, the U.S. Space Force will oversee installation and operation. The technology is already past prototyping. The military tested the system at two different locations earlier this year. The Department of Defense allocated funds to build 24 remote installations, with 11 scheduled to deploy before the end of the year. (ANS thanks SatNews.com for the above information.) + SpaceX Falcon 9 returned to flight with three Starlink launches in 30 hours after only 15 days of being grounded due to its recent upper-stage anomaly (a brittle, and presumably cracked, pressure monitoring line) and conducted its 300th reflight of a booster. (ANS thanks The Orbital Index for the above information.) + Boeing performed a hot fire test of the 27 maneuvering thrusters aboard the docked Starliner space capsule, which could be the last test before the spacecraft’s delayed return to Earth is approved. Astronauts Barry “Butch” Wilmore, and Sunita Williams, KD5PLB, took Starliner to the International Space Station on June 5 for what was to have been a 10-day test flight. NASA says they may now return in late August. (ANS thanks The Orbital Index for the above information.)

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not.

I will be monitoring the contact on Wednesday to the Kopernik laboratory. When the transmissions and contact are finished if the astronaut switches to the cross band repeaterand is free I will be there to try to make a qso with them from fn35cl as they pass over my qth in quebec canada.Can you please pass on my message to the ISS.

ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. The Kopernik Observatory & Science Center is a non-profit informal educational institution that promotes interdisciplinary education in the fields of Science, Technology, Engineering and Mathematics (STEM). This year is the 32nd summer of Kopernik STEM camps for students between 2nd and 12th grades. One of the camps offered this summer is entitled “Welcome Aboard the ISS”, where rising 5th and 6th grade students will learn about what it takes to become an astronaut, how they train for a mission and what research is being done on the ISS. Opened in 1974, Kopernik is celebrating its 50th anniversary as a STEM education resource in the region. Kopernik’s resources include three permanent telescopes, a heliostat, weather station, three classrooms, computer lab, portable planetarium and amateur radio station (K2ZRO). It also offers an outreach program in which its educators bring programs directly into the classroom. Kopernik is the home of the Kopernik Astronomical Society and the Binghamton Amateur Radio Association (W2OW) whose members are supporting observatory staff in the set up and radio station operation during this ARISS contact. This will be a direct contact via amateur radio allowing students to ask their questions of astronaut Matthew Dominick, amateur radio call sign KC0TOR. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contact is in Vestal, NY. Amateur radio operators using call sign K2ZRO, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 31, 2024 at 2:17:25 pm EDT (NY) (18:17:25 UTC, 1:17 pm CDT, 12:17 pm MDT, 11:17 am PDT).

How does training underwater compare to the feeling of weightlessness in space? Does it actually feel pretty similar? 2. Looking out to space from the ISS, in what ways does it look different from a night sky on Earth? 3. Is artificial gravity just science fiction or a possibility in the future? 4. Does the ISS have any engine powering it forward? 5. How did they keep the ISS in orbit before there were astronauts on it and in between missions? 6. If the sun is the center of our solar system, and gives heat and light to the other planets, why is space cold and dark and not bright and hot? 7. What does a sunrise look like on the ISS? 8. What does Space sound like? 9. How long was your training for this ISS mission? 10. What's it feel like to experience a rocket launch? 11. What was your inspiration to want to become an astronaut? 12. What is the most challenging thing you have encountered as an astronaut on the ISS? Did you create a solution or overcome it? 13. How do you get enough air on the International Space Station? 14. Do you eat food from a bag? 15. Can I go to space? 16. Is it hard or easy to pick things up in the vacuum of space? 17.

This initiative, a collaboration between the Israel Space Agency (ISA) and Tel Aviv University, has been a key educational tool, providing practical experience in satellite technology to students across Israel. Launched in January 2022 on the SpaceX Falcon 9 Transporter-3 mission, the TEVEL satellites were part of a broader effort to promote STEM education. The CubeSats, built to the 10x10x10 cm standard, were used for various missions including scientific data collection, amateur radio communication, and technology experimentation. The project aimed to enhance students' understanding of satellite technology and prepare them for careers in the space industry. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Students-Assembl…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Students-Assembl…> Students assembling a satellite as part of the TEVEL program. [Credit: Israel Space Agency] In addition to their educational value, the TEVEL satellites played a significant role in the amateur radio community. Equipped with radio transponders, they allowed amateur radio operators worldwide to communicate via satellite, fostering international collaboration and technological experimentation. This feature provided a unique platform for enthusiasts to engage in satellite communication. As the satellites now re-enter Earth's atmosphere, this phase marks the end of their operational lives. The reentry process, which involves the satellites burning up upon reentry to prevent space debris, is being monitored by both educational teams and the broader space community. This final stage offers a valuable learning opportunity for students tracking the satellites' descent and analyzing the data. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/TEVEL-One-Throug…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/TEVEL-One-Throug…> All eight TEVEL CubeSats are expected to decay from orbit in the next few weeks. [Credit: Nanosats.eu] Looking ahead, David Greenberg, 4X1DG, has announced a new TEVEL mission featuring nine additional satellites, continuing the educational and amateur radio goals of the original initiative. The decommissioning of the TEVEL satellites highlights the importance of responsible satellite disposal to minimize space debris and ensure the sustainability of space operations. The success of the TEVEL project sets a precedent for future educational satellite initiatives, demonstrating how hands-on learning can be integrated with practical space missions. As the satellites complete their final descent, they leave behind a legacy of inspiration and international collaboration in both educational and amateur radio fields.

Among these missions was PariSat, a project that highlights the ingenuity and dedication of the Garef Aérospatial club. This amateur space club, comprised of young engineers aged 15 to 25, has been working diligently on satellite testing, with the goal of exploring how different materials handle heat dissipation in space. The core of the PariSat experiment is to determine which materials are most effective at dissipating heat in the harsh environment of space. The project, however, is not just about the scientific results but also about the educational journey for the young engineers involved. Based in a modest building near the Georges Carpentier stadium in Paris's 13th district, the club members work after school, applying their passion for space to design and build their satellite experiment. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/PariSat_Captures…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/PariSat_Captures…> Earth image captured by an adapted GoPro camera used on PariSat. [Credit: Garef Aérospatial] PariSat features eight small square plates, each just 4 cm wide, which function as space radiators. These plates were chosen to test various properties such as material composition and color, and their responses to heating and cooling. Equipped with temperature sensors, each plate provided data on "black-body radiation" during the nearly three-hour flight of Ariane 6's upper stage. This data will help validate the Stefan-Boltzmann law of thermal radiation, a principle discovered in 1884. In addition to the scientific experiment, PariSat includes a photo component. The team has adapted a GoPro camera for space use, which is controlled by a module entirely designed by Garef Aérospatial. This camera, featuring a fisheye lens, captured stunning images of Earth, showcasing the planet's curvature and adding a visual dimension to the mission. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Ariane_6_Payload…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Ariane_6_Payload…> Five experiments gathered data while attached to the Ariane 6's upper stage during its inaugural flight. [Credit: ESA] PariSat is part of a larger set of five experiments, including Peregrinus, Sidloc, LiFi, and YPSat, which also remained attached to the Ariane 6's upper stage during its three-hour flight. These experiments gathered data as the upper stage's orbit was adjusted by the Vinci engine, which can be restarted multiple times. The collected data was transmitted back to Earth and received by the Swedish Space Corporation's telemetry station in Kiruna, Sweden. As the Garef Aérospatial team begins analyzing the data, the PariSat mission serves as a testament to the capabilities of young engineers and highlights the potential for youth-led initiatives in space science. With this mission, the team looks forward to future projects, driven by the experiences and successes gained from their participation in Ariane 6's first flight.

This development comes as part of a contract awarded to SpaceX on June 26, valued at up to $843 million. The new spacecraft, known as the United States Deorbit Vehicle (USDV), was detailed by NASA and SpaceX officials at a briefing on July 17th. The USDV will be based on SpaceX's existing Dragon spacecraft but will feature a redesigned and larger trunk section with additional thrusters. Specifically, the USDV will have 46 Draco thrusters, including 16 for attitude control and 30 for the maneuvers required to lower the ISS's orbit. Sarah Walker, SpaceX's director of Dragon mission management, explained that the enhanced trunk section is twice as long as the regular one. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/SpaceX-United-St…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/SpaceX-United-St…> NASA presented the concept of the US Deorbiting Vehicle designed by SpaceX on July 17th. [Credit: SpaceX] The new trunk will house engines, propellant tanks, power generation, and other systems, storing six times the propellant of the current Dragon spacecraft and generating three to four times the power. "It's almost a spacecraft in and of itself," Walker noted. Once completed, NASA will own and operate the USDV, which will be launched to the ISS shortly after the station's final crew arrives. After its arrival and successful checkout, ISS controllers will allow the station's orbit to naturally decay. The final crew will depart when the station's altitude decreases from its current 400 kilometers to 330 kilometers. The ISS's orbit will continue to decay over approximately six months before NASA uses the USDV for a final controlled deorbit, targeting a remote ocean corridor about 2,000 kilometers long. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Crew-6-Dragon-Ca…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Crew-6-Dragon-Ca…> The SpaceX Dragon capsule Endeavour which flew the Crew-6 mission on March 2nd, 2023. [Credit: SpaceX] Dana Weigel, NASA ISS program manager, mentioned that debris from the station, ranging in size from a microwave oven to a sedan, is expected to survive reentry and splash down in this corridor. The USDV will have an estimated mass of over 30,000 kilograms, including 16,000 kilograms of propellant. Due to its size, it will require a heavier class of rocket than the Falcon 9 currently used for Dragon missions. NASA plans to procure the launch vehicle separately at least three years before the launch. SpaceX expressed readiness to support the launch if given the opportunity. Northrop Grumman was the only other company to bid on the USDV. NASA's source selection statement indicated that Northrop's bid was significantly higher in price and rated lower in both mission suitability and past performance compared to SpaceX. Ken Bowersox, NASA associate administrator for space operations, expressed satisfaction with the proposals received, noting he was pleased with the submissions from SpaceX and Northrop Grumman.

Upon arrival at KSC, the core stage was transferred to a self-propelled transporter and moved into the iconic Vehicle Assembly Building (VAB). Engineers will soon begin processing the stage for stacking operations, involving the integration of the twin Solid Rocket Boosters (SRBs) and the spacecraft. The Space Launch System (SLS) rocket's twin boosters and the core stage's four RS-25 engines will generate nearly 9 million pounds of thrust at liftoff, propelling Artemis-2 and its crew to the moon. (ANS thanks Mike Killian, AmericaSpace.com<https://www.americaspace.com/>, for the above information) + NASA astronauts Butch Wilmore and Sunita Williams will remain at the International Space Station (ISS) with no set return date due to ongoing technical issues with Boeing's Starliner capsule. The astronauts departed for the ISS in early June on a test mission expected to last about a week, but faulty thrusters and helium leaks have delayed their return. Despite some thrusters now functioning normally and the leaks being stable, NASA and Boeing are still not ready to schedule their departure. NASA assures that the astronauts are not stranded and the technical issues do not pose a threat to the mission. Engineers are conducting tests, including on a spare thruster in New Mexico, to understand and resolve the problems. Steve Stich, NASA's commercial crew program manager, emphasized the priority of the astronauts' safety and the consideration of backup return options. (ANS thanks Anna Betts, The Guardian<https://www.theguardian.com/>, for the above information) + SpaceX is set to resume Falcon 9 launches as early as July 27 following the completion of an investigation into an upper stage anomaly from the July 11 launch. The mishap, which resulted in the rocket's upper stage failing to perform a second burn and stranding Starlink satellites in a low orbit, was attributed to a liquid oxygen leak caused by a cracked sense line. This crack was due to engine vibration fatigue and a loose clamp. The resulting leak led to ice buildup and excessive cooling of engine components, causing a hard start and subsequent damage to the engine hardware. SpaceX has implemented immediate fixes and proposed long-term solutions, and the FAA has determined that there are no public safety issues, allowing launches to proceed. SpaceX is targeting July 27 for the next launch, with two more launches tentatively scheduled for July 28.

Thanks for the frames, JoAnne! The one you got the other day came in REALLY handy...so you just never know the value of your efforts to get a working system and copy some frames. A reminder--the Transponder is OFF and will remain so for a while, while we help UMaine get the science data from their satellite. A teaser--a quick test suggests that the linear transponder operation looks pretty promising ;) Another reminder--getting our stations "up to snuff" to copy MESAT1 is good, fun, work! Consider copying MESAT1 telemetry a good benchmark for how well you can receive on 70cm. Happy telemetry collecting! 73, Mark L.

Thanks Chris! I had good copy on the beacon and decodes were flowing nicely during the Saturday morning pass. My camera tab on FoxTelem shows a few lines of the image. I'll hope for stronger signals later today. The higher power and continuous transmission made final tweaks a lot easier :-) Also on the IC-9700 I found that I've got use the MAIN RX (and not the SUB RX) for FoxTelem to get the data. I use 435.798 as the initial frequency as N8MH had recommended previously.

The MESAT-1 team are continuing to test and commission the satellite. It is currently in Health Mode transmitting continuously and the downlink power is now about 6dB higher. So it should be easier to hear and decode. If you have had trouble decoding it then now is a good time to try again. You may have seen some data from the on board Multispectral Camera Saturday morning. This was test data as part of the commissioning process. The team will attempt to capture and transmit new science data on the 01:53 UTC and 12.25 UTC passes over North America tonight and tomorrow. 73 Chris VE2TCP / G0KLA / AC2CZ -- Chris E.

ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. School Story: Nara City has a long history, with its capital established approximately 1,300 years ago. In addition, Nara Prefecture has many world heritage sites and is an international tourist city. This will be the first time ARISS School Contact will be held in Nara Prefecture. We selected the contact members from Sakyo Elementary School and Tsubai Elementary School in Nara City. This will be a direct contact via amateur radio allowing students to ask their questions of astronaut Mike Barratt, amateur radio call sign KD5MIJ. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contact is in Nara, Japan. Amateur radio operators using call sign JK3ZNB, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 29, 2024 at 7:52:51 pm JST (Japan) (10:52:51 UTC, 6:56 am EDT, 5:56 am CDT, 4:56 am MDT, 3:56 am PDT). The public is invited to watch the live stream at: https://www.youtube.com/watch?v=BQrUHun__6o *_______________________________* As time allows, students will ask these questions: 1. Yasuka (12) Can you see lightning on earth from space? 2. Haruto (9) What do you eat in space? 3. Rinto (10) Is the earth really green when seen from space? 4. Haruna (9) What kind of training does it take to go to space? 5. Yusei (11) How do you dispose of toilet waste? 6. Kohei (10) Have you ever seen any space debris while working outside the ISS? 7.

First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-07-23 23:30 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-07-18 15:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

Jim, Thanks for providing this info. Very interesting read. Do you know of any hi-res images taken of SO-50 before it was launched? I have always been kind of curious what the bird looks like. There are a few sites with images of it but 3 or 4 of them have conflicting images of obviously different cube sats. Thanks for being a part of building such a great FM sat. I can't even imagine the amount of amateurs that have had fun working SO-50 over the years. 73, Will KN6QVA On 7/22/24 3:39 PM, Jim White via AMSAT-BB wrote: > > Managing the battery discharge by adjusting current draws - by turning > things on/off or changing the power level of the transmitter, has been > done since the 1990 AMSAT Microsats (or the SSTL birds before them). > At least we did that in one the ones I worked on.

Supercapacitor lifetime: https://abracon.com/uploads/resources/Supercapacitor-Lifetime-Explained.pdf There seem to be a lot of papers on space-qualified supercapacitors, but no off-the-shelf space-qualified ones. The temperature range is one issue out of dozens. This would hardly be the first time that the most desirable component was pure unobtanium.

Managing the battery discharge by adjusting current draws - by turning things on/off or changing the power level of the transmitter, has been done since the 1990 AMSAT Microsats (or the SSTL birds before them). At least we did that in one the ones I worked on. I think it's still true that the most common cause of satellite failure is batteries doing bad, and the one's I'm familiar with were because the batteries got pulled down to the resting voltage (about 1V/cell for NiCads). They will reverse polarity or short when you mistreat them. With chemistries like LiPoly, if you mistreat them they just die, or explode. You prevent that by making sure you never pull the voltage too low, and by not overcharging them. Another feature in the Microsats was to reduce battery charging when they got near "full" by moving the solar panel off the optimum point in the I/V curve. I have seen many examples of missions that sat on the shelf for months with the battery (whatever chemistry) discharging. Then at separation they turn on a bunch of stuff and, drew the batteries into the ditch, reset, and maybe came back on. And a few that did that over and over until operators managed to stop it by command. Or they died. In the Microsats, and others I worked on, we took a very conservative approach. At sep, turn on only what is absolutely needed, beacon at a slow rate and lower power, let the batteries charge up and let the operators decide when to turn on the ACS or other stuff - after being sure there was enough power available. So to the extent batteries are managed properly as in Falconsat 3 and SO50, yes, that definitely extends the life. Having said that if you design goal is a year of operation at higher TX power with a full ACS running, or gathering a lot of science data, you accept the satellite life will be shorter. It's all a trade-off. Actually, many trade-offs all tangled up with each other.

Batteries are often the first major things to fail. (AO7 failed then re-awoke when the battery open circuited). I would suggest instead of having a battery, use ultra capacitors to help even out the power from the solar cells when in sunlight, and, have no transponder operation when in eclipse. Additional advantages are: (1) ultra capacitors are lighter than a battery, (2) the solar cells need only supply the transponder, whereas there needs to be extra solar cells to also recharge the discharged battery when the bird is in sunlight. The only disadvantage is the transponder is non operational during eclipse periods, which, in reality, is no big issue. 73 Starr ZL3CU On 23/07/2024 5:15 am, JOHN GEIGER via AMSAT-BB wrote: > Thanks for the information on all of those things.
