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.

Re: SO-50 Key to Longivity?
by Jim White 22 Jul '24

I'll provide a bit of input here since I worked on SO50. Here are some considerations. - The hardware was mostly built by SpaceQuest and used proven designs that had been flown several times - The design goal was long life. The orbits would provide that, unlike some current launches were the orbit will last a shorter time. The idea was to provide a long life resource for all to use. - The software followed proven designs dating back to the 1990 Microsats. All software except the boot loader (in rad protected RAM) was uploadeable. The SCOS real-time operating system allowed individual tasks to be killed and uploaded without disturbing other tasks or the OS. SCOS was quite robust. - There were no I2C busses to latch up, and no flash cards (both of which cause problems in current designs) - The program memory was rad hard, the OS 'washed' that memory every 10 minutes to eliminate bit flips from passing through the SAA. The data memory used Huffman software rad recovery. - Antennas we not deploy-able and were made of piano wire so were quite robust. - The batteries were NiCAD so were robust and hard to hurt. They work fine over a wide temperature range and don't need heaters. Don't need to manage charging as carefully and don't need to be concerned about not charging if outside a temp range. - The software automatically adjusted TX power output to prevent pulling the battery V too low and causing a reset. There were three steps of battery management, each turning off more stuff to reduce load and attempt to prevent full discharge. - Batteries were very carefully matched using the process first developed for the Microsats. - The power system included adjusting the solar panel input impedance to constantly maximize power from the panels. And another algorithm prevented overcharging. A manual process is used to adjust those algorithms as the battery capacity drops with time and the panels loose efficiency. - The software kept the dept of discharge of the batteries to no more than about 20%, resulting in much longer battery life.

It's a microsat size satellite, so significantly larger than current cubesat form factors.2. It's transmit power is just 250 mW and it transmits only while it receives a signal with a 67 Hz PL tone - there's no constant carrier or any telemetry transmissions. I'm not aware of any other payloads or signals coming from the satellite. Potentially there's not even any onboard computer drawing power. 3. Given its size, it has fairly large solar cells and likely has fairly large battery cells and given its transmit setup, the depth of discharge is likely quite low. NiCd batteries can last a real long time when the depth of discharge is kept quite low. 73, Paul, N8HM On Mon, Jul 22, 2024 at 12:05 PM JOHN GEIGER via AMSAT-BB <mailto:[email protected]> wrote: SO-50 will be 22 years old in December and seems to be still be going strong, in sunlight and in eclipse.

Re: SO-50 Key to Longivity?

1. It's a microsat size satellite, so significantly larger than current cubesat form factors. 2. It's transmit power is just 250 mW and it transmits only while it receives a signal with a 67 Hz PL tone - there's no constant carrier or any telemetry transmissions. I'm not aware of any other payloads or signals coming from the satellite. Potentially there's not even any onboard computer drawing power. 3. Given its size, it has fairly large solar cells and likely has fairly large battery cells and given its transmit setup, the depth of discharge is likely quite low. NiCd batteries can last a real long time when the depth of discharge is kept quite low. 73, Paul, N8HM On Mon, Jul 22, 2024 at 12:05 PM JOHN GEIGER via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > > SO-50 will be 22 years old in December and seems to be still be going > strong, in sunlight and in eclipse.

ANS-203 AMSAT News Service Weekly Bulletins
by Paul Stoetzer 21 Jul '24

21 Jul '24

*AMSAT News Service* *ANS-203* *July 18, 2024* In this edition: - AMSAT Board of Directors Election Underway - AMSAT Mail Alias Service to End August 31, 2024 - Tevel Satellites Nearing Re-Entry - AMSAT-OSCAR 7 in Continuous Sunlight - Changes to AMSAT TLE Distribution for July 19, 2024 - ARISS News - Upcoming Satellite Operations - AMSAT Ambassador Activities - Satellite Shorts From All Over The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, The Radio Amateur Satellite Corporation. 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 https://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 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/ ------------------------------ Save the Date! Symposium 2024 Photo by Robert DuBois Mark your calendar now for the 2024 AMSAT Symposium, *October 25-27, 2024 *at the Doubletree by Hilton Tampa Rocky Point Waterfront in Tampa, Florida! Watch for announcements concerning further details as plans are formulated. ------------------------------ AMSAT Board of Directors Election Underway The nomination period for the 2024 AMSAT Board of Directors Election ended on June 15th. 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 AMSAT for the above information]* ------------------------------ Tevel Satellites Nearing Re-Entry The Tevel series of satellites is approaching re-entry, with Tevel-5 already re-entering on July 18th. The Tevel mission consists of 8 satellites developed by the Herzliya Science Center in Israel, each carrying an FM transponder. The satellites were built by 8 schools in different parts of Israel and launched in January 2022 on the SpaceX Falcon 9 Transporter-3 mission. A number of other satellites with amateur radio payloads are also re-entering shortly. A list of satellites approaching re-entry can be found at http://lu7aa.org/decay.asp *[ANS thanks Herzliya Science Center, AMSAT Argentina, and LU7AA 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!* ------------------------------ AMSAT-OSCAR 7 in Continuous Sunlight AMSAT-OSCAR 7, soon to celebrate its 50th birthday on November 15, 2024, is now in a period of continuous sunlight through May 22, 2027. While in continuous sunlight, the satellite's internal timer is expected to switch between the two transponders - Mode A (29 MHz downlink and 145 MHz uplink) and Mode B (145 MHz downlink and 29 MHz uplink) every 24 hours. Post reports and check current status on the AMSAT Live OSCAR Satellite Status Page <https://www.amsat.org/status/>. After a few days in continuous sunlight, it should be possible to determine the actual or approximate time the satellite switches. *[ANS thanks AMSAT and EA1PA for the above information]* ------------------------------ Changes to AMSAT TLE Distribution for July 19, 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: MESAT1 remains on this distribution. No signals have been detected from any other amateur spacecraft launched as part of NASA's ELaNa 43 mission.

TEVEL 5 and 6 had perigees well under 200 km associated with their last published TLE sets, so they are almost certainly part of our atmosphere at this point. The remaining TEVEL satellites are a little higher, they will remain in orbit for another 2 weeks or so.

(***) 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.

Re: MESAT1 telemetry with FlexRadio

Hello JoAnne and friends--- For the IC-9700 I'm using just USB (not USB-D) and have reset the filters as wide as possible for that mode (all three in fact, so it's always the right one, hihi).. I can print using audio over USB or from the ACC1 jack on the back into an external sound card, so we have several options for getting audio.from the 9700. In Foxtelem, be sure to use Telem Format "BPSK 1200bps LTM". I try to adjust the RX frequency so the bottom left screen shows "Carrier: " values of about 1200-1500. The TLEs are good and have been, which makes the Doppler corrections good enough for automation. I'm working on the station at the university and need to tweak a few things, but the M2 Leo pack is just enough to print the bird when elevations are "good". The preamp is inside, so fixin' that is in the near future. So, keep at it, group! This is an opportunity for many of us to work on the 70cm receiving sensitivity of our stations--that's what I'm doing ;) 73, Mark L.

Charlie and David, Thanks for the pointers. I've found a couple of things to tweak based on your messages. I'm using the S.A.T. tracker box so I don't have SQF files - but I've tweaked it's satellite frequency there so I'm hoping I'll be closer to the frequency. I'm using my Greencube setup where the IC-9700 received USB-D audio goes into the UZ7HO soundmodem then the OZ9AAR terminal. I hope that I'm not too far off track substituting the FoxTelem software configuration in place of the Greencube software configuration.

Re: MESAT1 telemetry with FlexRadio
by Charles Rubenstein 16 Jul '24

I am using a Flex 6600M with Q5 Xvrtrs. Here is what I’m using for MESAT1 telemetry. I am using a download frequency of 435798.5. You should use USB (DIGIU on the Flex) Make an entry using this downlink frequency in your Doppler.SQF file, and restart SatPC32. Make sure you are using DAX Audio RX1, not DAX IQ. In the telemetry software, I also checked the box “find signal” (I think this might be AFC) Make sure you also check the box to upload data. I have successfully captured data from 8 passes. The satellite isn’t real strong, but it has been improving. The best passes here in EM79 have been early mornings (before I wake up hi hi) but I had success with that setup.

Hello Christy, Per IARU entry at https://iaru.amsat-uk.org/finished_detail.php?serialnum=963 shows 'FX.25 FEC144-146MHz optional: 9600 baud, GMSK' The exact frequency is not yet known, which should be between 145.8 ~ 146 and whether it will be uplink or simply downlink.

MESAT1 telemetry with FlexRadio
by Mark Johns, K0JM 16 Jul '24

16 Jul '24

I am having trouble decoding MESAT1 telemetry. I'm using a FlexRadio with Down East Microwave (DEMI) transverter and the latest FoxTelem software. The signals are strong, but I'm getting no decodes, and the transmissions aren't long enough to get things properly set up. If anyone else out there is successfully using a similar setup, I'd like to hear from you off list. Thanks! -- Mark D.

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 2024-07-16 04:00 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 2024-07-11 16:00 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.

*ARISS News Release No. 24-39* *Dave Jordan, AA4KN * *ARISS PR* *aa4kn(a)amsat.org <aa4kn(a)amsat.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Scouts at * *Hokusetsu District Osaka Council Scout Association of Japan, Toyonaka, Japan* July 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 scouts located in Toyonaka, Japan. 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 Hokusetsu District is located in the northern part of Osaka Japan and has 670 Scout members in 24 Groups. Their scouts are made up of elementary school students, junior high school students, high school students, and university students with 450 scout leaders. Members of the amateur radio club in the Hokusetsu area (JJ3YDM) play an important role in mentoring these scouts in the practice of amateur radio. 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 Toyonaka, Japan. Amateur radio operators using call sign JJ3YDM, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 18, 2024 at 5:23:52 pm JST (Japan) (8:23:52 UTC, 4:23 am EDT, 3:23 am CDT, 2:23 am MDT, 1:23 am PDT). *_______________________________* As time allows, students will ask these questions: 1. Do you have an internet connection in the ISS? 2. What made you want to become an astronaut? 3. What kind of experiments do you have? 4. Is there any experience you had as a child that was useful to be an astronaut? 5. How many hours a day do you sleep? 6. What do you do in your spare time in space? 7. Do you feel your clothes are floating? 8. Where do you land when you get back to the earth? 9. What was the most difficult training to become an astronaut? 10. Do you feel the time passing in space? 11. Do you miss the Earth? 12. What do you do when you lose something? 13. What space food do you like? * 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.

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 2024-07-15 17:30 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 2024-07-11 16:00 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.

Hi Douglas, those are tlm frames from UHF radio, radios are the same as BDSAT, BDSAT2, Planetum and Veronica, so you can search for their webpages for frames description.

How do you decode the numerical data from GRBBETA ?

Help Support GOLF and Fox Plus [cid:[email protected]] Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ________________________________ Grace Papay, K8LG Named 2024 WA6ITF Memorial Amateur Radio Newsline Young Ham of the Year Grace Papay, K8LG, of Holland, Michigan, has been selected as the 2024 Bill Pasternak WA6ITF Memorial Amateur Radio Newsline Young Ham of the Year. Grace, 18, is the daughter of Doug Papay, K8DP, and Carrie Papay K8CLP. Grace earned her Technician license in March 2021 and within a year achieved her Extra Class license, passing the test in March 2022. She is a recent honors graduate of Holland Christian High School in her hometown, where she earned a varsity letter in the Unified Sports program. Grace credited her father and her grandfather, John Papay, K8YSE, a well-known operator in the ham radio satellite community, for drawing her into the hobby. “I got involved in amateur radio satellites,” Grace recalls. “I got on the air. And now it has turned into something from honoring my grandfather to a hobby I’m on every day and I love.” With support from her grandfather and father, she earned the DX Century Club certificate for contacts exclusively using satellites. Grace attended Youth on the Air camps in Cincinnati in 2022 and Ottawa in 2023, where she says she was exposed to a variety of other amateur radio activities including balloon launches, slow-scan television and radio contesting. She was part of the K3LR IOTA Dave Kalter Memorial Youth DX Adventure in 2023 and was a team member for the J62K St. Lucia DX contest operation in 2024. Grace is active on the HF bands and operates in the ARRL and CQ DX SSB and CW contests, ARRL Sweepstakes and CQ WPX, as well as Youth on the Air events. For the past few years, Grace has been a regular presenter at the Youth Forum at Dayton Hamvention. She delivered a presentation on youth in contesting at the Contest University Forum at Dayton this year and assisted at the YOTA and AMSAT booths. She is an active member of the Holland Amateur Radio Club, Grand Rapids Amateur Radio Association, West Chester Amateur Radio Association and the American Radio Relay League. Grace received the Radio Club of America’s Young Achievers Award in 2023. She had an article on the “Next Generation of Contesters” published in the National Contest Journal (Nov/Dec 2023). A story she co-wrote on YOTA Camp 2022 appeared in the August 2022 edition of CQ magazine. Grace will be attending Cedarville University in Cedarville, Ohio this fall, where she will study electrical engineering. She says amateur radio played a major role in her choice of a major. The YHOTY award will be presented to Grace during a ceremony at the Huntsville Hamfest on Saturday, Aug. 17, 2024 at the Von Braun Center in Huntsville, Alabama. Amateur Radio Newsline and Yaesu USA are primary sponsors of the award, along with Heil Sound Ltd. and Radiowavz Antenna Company. The Young Ham of the Year Award was inaugurated by William Pasternak, WA6ITF, in 1986. Upon his passing in 2015, Bill’s name was added to the award as a memorial to his commitment to recognizing the accomplishments of young people to the Amateur Radio Service.

Other files and URLs with "nasa" and "ftp" in the URL are still maintained to support older software, but suggest organizations protocols that are no longer involved in TLE dissemination. Use of older filenames and URLs is deprecated and AMSAT does not promise to maintain them in perpetuity. End users and software developers are encouraged to use the URLs above going forward. The files are available via HTTPS (preferred) as well as unencrypted HTTP for legacy software. [ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager/IT Team for the above information.] ________________________________ Need new satellite antennas? Purchase M2 LEO-Packs from the AMSAT Store. [cid:[email protected]] When you purchase through AMSAT, a portion of the proceeds goes towards Keeping Amateur Radio in Space. https://amsat.org/product-category/hardware/ ________________________________ Updating Keps in SatPC32 - An Update from DK1TB Erich Eichmann, DK1TB, SatPC32 author offers this update: "The SatPC32 Update Keps feature doesn't work with https links for TLE files. That would require changes of the source code and maybe requires a new Delphi version for me. I will care about that but that will at least take time and at present I don't have much time for the hobby. "But all https websites can be accessed also with http. They are not "secure" sites but that is meaningless with websites that contain Keps. Therefore use http in the aux. file Celestrak.SQF for AMSAT and Celestrak TLE (Two Line Elements) files, as described by Charlie, AJ9N, see below. With that modification the Download Keps function works. "Also, the https links can be accessed with your browser, of course. Enter the links into the address line of the browser. So, you can download the Keps and save them in the SatPC32 data folder 'Kepler' (see path to that folder in the footline of menu 'Satellites'). "By the way - Meanwhile my website supports also SSL. You can access it with https://www.dk1tb.de and https://www.dk1tb-2.de. "Also, SatPC32 supports now, besides TLE files, the new formats for Keps files XML, KVN and CSV. Celestrak publishes the Keps files also in these formats. The SatPC32 UpdateKeps feature works with these files also when downloaded from https sites (I don't know why that is different versus the TLE files). Therefore you can use https in Celestrack SQF with these files such as https://celestrak.org/NORAD/elements/gp.php?GROUP=amateur&FORMAT=xml." [ANS thanks Erich Eichmann for the above information.] ________________________________ NASA Discovers Strange Spectral Formations Cover LEO Orbits NASA scientists have spotted unusual shapes in the Earth's ionosphere, hundreds of miles above the Earth's surface. [cid:[email protected]] The ionosphere stretches from 50 to 400 miles above the planet and marks the boundary between our planet's atmosphere and outer space. While it houses most satellites orbiting the Earth, it's vulnerable to changes in space weather — electromagnetic radiation emitted by the Sun — that can wreak havoc in the zone and mess with communications equipment. Under some conditions, the layer can become electrically charged. As detected by the Global-scale Observations of the Limb and Disk (GOLD) imaging instrument, plasma bands stretching across the ionosphere can result in formations of unusual X and C shapes. It's a baffling "alphabet soup," as NASA termed the findings in a news release, that could shed light on how space weather can influence our planet's upper atmosphere and "interfere with radio and GPS signals." Charged particles can create dense bands or "crests" around the Earth's magnetic equator, while low density pockets caused by the setting Sun can result in "low-density pockets" called 'bubbles," according to NASA. Scientists believe that larger disturbances such as solar storms or even massive volcanic eruptions can cause multiple crests to merge and form an "X" shape, as previous GOLD observations have shown. But now, scientists have spotted these same shapes without any such occasion, during what scientists call "quiet time." "Earlier reports of merging were only during geomagnetically disturbed conditions — it is an unexpected feature during geomagnetic quiet conditions," said University of Colorado research associate Fazlul Laskar, who lead-authored a paper on the discovery earlier this year, in a NASA statement. Scientists are now wondering if something else could be causing these X shapes to appear. "The X is odd because it implies that there are far more localized driving factors," said NASA scientist and ionosphere expert Jeffrey Klenzing. "This is expected during the extreme events, but seeing it during ‘quiet time’ suggests that the lower atmosphere activity is significantly driving the ionospheric structure." Apart from X shapes, some bubbles in the ionosphere can also curve into C shapes, which new observations show can appear in close proximity to each other. In short, there's a lot still to learn about our planet's magnetically charged, protective shell. "The fact that we have very different shapes of bubbles this close together tells us that the dynamics of the atmosphere is more complex than we expected," Klenzing added.

Upcoming ARISS Contact Schedule as of 2024-07-11 16:00 UTC Quick list of scheduled contacts and events: Houjoudu Elementary School, Imizu, Japan, direct via JA9YQJ 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 Mike Barratt KD5MIJ The ARISS mentor is 7M3TJZ Contact was successful: Thu 2024-07-11 10:48:03 UTC 83 deg (***) Congratulations to the Houjoudu Elementary School students, Mike, mentor 7M3TJZ, and ground-station JA9YQJ! (***) Hokusetsu District Osaka Council Scout Association of Japan, Toyonaka, Japan, direct via JJ3YDM 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 Mike Barratt KD5MIJ The ARISS mentor is 7M3TJZ Contact is go for: 2024-07-18 08:23:52 UTC 49 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 2024-07-11 16:00 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 2024-07-11 16:00 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 used to monitor telemetry from the older FOX satellites with a slower laptop running an SDR. I found that I had to wait for the 'Queue' in the lower right corner of the FoxTelem panel to go down to zero before exiting FoxTelem otherwise my most recent bytes wouldn't show. Sometimes it took a minute or two for the upload queue to empty. On 7/10/2024 1:26 PM, Chris Thompson via AMSAT-BB wrote: > Well done!

Hi John, yes, that's the right mode to select. What are you using to receive? Running Foxtelem is pretty straightforward, once you get the audio coming into the program populate the settings menu--including the selection of "upload to server!" Mark L.

Re: amsatbare.txt file

Hi, The SatPC32 Update Keps feature doesn't work with https links for TLE files. That would require changes of the source code and maybe requires a new Delphi version for me. I will care about that but that will at least take time and at present I don't have much time for the hobby. But all https websites can be accessed also with http. Then they are no "secure" sites but that is meaningless with websites that contain Keps. Therefore use http in the aux. file Celestrak.SQF for AMSAT and Celestrak TLE (Two Line Elements) files, as described by Charlie, AJ9N, see below. With that modification the Download Keps function works. Also, the https links can be accessed with your browser, of course. Enter the links into the address line of the browser. So, you can download the Keps and save them in the SatPC32 data folder 'Kepler' (see path to that folder in the footline of menu 'Satellites'). BTW: Meanwhile my website supports also SSL. You can access it with https://www.dk1tb.de and https://www.dk1tb-2.de Also, SatPC32 supports now - besides TLE files - the new formats for Keps files XML, KVN and CSV. Celestrak publishes the Keps files also in these formats. The SatPC32 UpdateKeps feature works with these files also when downloaded from https sites (I don't know why that is different vs. the TLE files). Therefore you can use https in Celestrack. SQF with these files, eg. https://celestrak.org/NORAD/elements/gp.php?GROUP=amateur&FORMAT=xml 73s, Erich, DK1TB Am 07.07.2024 um 18:00 schrieb Charlie Sufana via AMSAT-BB: > Based on all of the email traffic on this, I thought I would modify my > sqf file with the newest file names.

Yaesu G-5500DC trouble shooting?
by Tom Kenny 09 Jul '24

09 Jul '24

I purchased a new Yaesu G-5500DC.Ensured continuity for each pin on the female connector to the corresponding screw on the controller box. Meaning pin 1 to screw 1 and so on. I only connected the Azimuth so far.I powered the control box turn it on and depress the left button and then the right button and nothing happens. I was expecting the azmuith rotator to turn...I rechecked continuity from the pins on the female connector to the screws on the controller box and they all seemed good. However, I noticed that screws 4 and 5 on the control box have continuity for azmuith. Is this normal? I noticed that scres 4 and 5 of the elevation screws also have continuity... Does anybody have any suggestions on troubleshooting? Are there other forums more appropriate for this topic? Thanks for any advise! 73, Tom NJ2DX

ARISS News Release No. 24-38
by David H Jordan 09 Jul '24

09 Jul '24

*ARISS News Release No.24-38* *Dave Jordan, AA4KN * *ARISS PR* *aa4kn(a)amsat.org <aa4kn(a)amsat.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Students at * *Houjoudu Elementary School, Imizu, Japan* July 9, 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 Houjoudu Elementary School located in Imizu, Japan. 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. Imizu City Houjoudu Elementary School in Toyama Prefecture has a 150-year history, and currently has 103 students. The Shinminato Amateur Radio club is assisting with this ARISS contact. Students have been preparing for this ARISS contact by watching images of the ISS and learning about Miura folding, a variation of the ancient Japanese tradition of origami. Miura folding method is named for Koryo Miura of Tokyo University's Institute of Space and Aeronautical Science who was looking for efficient ways to fold and unfold the solar panels of spacecraft so that they can fit inside a rocket then unfurl in orbit to catch the sun’s rays. Miura folding method allows it to be easily opened and closed by applying force in one direction. 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 Imizu, Japan. Amateur radio operators using call sign JA9YQJ, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 11, 2024 at 7:48 pm JST (Japan) (10:48 UTC, 6:48 am EDT, 5:48 am CDT, 4:48 am MDT, 3:48 am PDT). _______________________________ As time allows, students will ask these questions: 1. Can you use a mobile phone in the ISS? 2. Have you ever seen an alien? 3. Is it cold or hot in space? 4. Do you have trouble eating and drinking? 5. How fast does the spaceship fly? 6. How do you feel with no gravity? 7. What kind of feeling do you have watching the Earth from space? 8. Were you scared to go to space? 9. What is your favorite space food? 10. What is the first thing you want to do when you return to Earth? 11. What would you do if you got sick or had cavities on a spaceship? 12. Why did you decide to become an astronaut? 13. How much does the space suit weigh? 14. How do you sleep in zero gravity? Would you like to lie down? 15. What has been the biggest challenge you’ve faced adapting to life on the space station? *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. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN) and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.

(***) 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.

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 International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ARISS Contact Applications (Europe, Africa and the Middle East) Schools and Youth organizations in Europe, Africa and the Middle East interested in setting up an ARISS radio contact with an astronaut on board the International Space Station are invited to submit an application from September to October and from February to April.

Mesat-1 is transmitting bpsk telemetry continuously. If stations in Europe have the chance to collect telemetry on the 1830 and subsequent passes, then that would be appreciated. This is receivable with a 10 element CP Yagi (the leo pack) or better at present. It is visible in the water fall for most stations. 73 Chris

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.

AMSAT TLE dissemination.
by Joseph Fitzgerald (KM1P) 07 Jul '24

07 Jul '24

AMSAT with help from its partner New England Sci-Tech prepares a bulletin of orbital elements during the first hour of the UTC day, and posts it to https://www.amsat.org/tle/daily-bulletin.txt<http://www.amsat.org/tle/daily-bulletin.txt> as well as "bare" elements without the bulletin header and footer at https://www.amsat.org/tle/dailytle.txt<http://www.amsat.org/tle/dailytle.txt> . Other files and URLs with "nasa" and "ftp" in the URL are still maintained to support older software, but suggest organizations protocols that are no longer involved in TLE dissemination. Use of older filenames and URLs is deprecated and AMSAT does not promise to maintain them in perpetuity. End users and software developers are encouraged to use the URLs above going forward. The files are available via HTTPS (preferred) as well as unencrypted HTTP for legacy software. Joe Fitzgerald (KM1P) AMSAT Orbital Elements Manager/IT Team

AMSAT NEWS SERVICE ANS-189 In this edition: * Firefly Delivers New Amateur Satellites to Orbit * Ariane 6 Maiden Flight With GENESIS-A Module * Logbook of The World Returns To Service * LUSAT, Dead or Alive? * LEGO Bricks Printed out of Space Dust * Field Day Submissions Now Due * Changes to AMSAT-NA TLE Distribution * ARISS News * Upcoming Satellite Operations * AMSAT Ambassador Activities * Satellite Shorts From All Over The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, the Radio Amateur Satellite Corporation. 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-189 AMSAT News Service Weekly Bulletins DATE 2024 July 7 Firefly Delivers New Amateur Satellites to Orbit The Firefly Alpha FLTA005/NASA ELaNa 43 mission, nicknamed “Noise of Summer,” launched successfully at 04:04 UTC on July 4 (Wednesday evening, July 3 in the U.S.) and deployed eight new cube satellites to Low Earth Orbit (LEO). Five of these cubesats carry amateur radio equipment. The cubesats were placed into a sun-synchronous Earth orbit, meaning that all locations on earth will see high-elevation passes roughly between 8:00 and 10:00 a.m. and between 8:00 and 10:00 p.m. local time daily, with lower elevation passes earlier and later. Among the newly-deployed satellites, the one of greatest interest to the amateur radio community is *MESAT1*. Built by the University of Maine, in cooperation with AMSAT, this satellite carries a 30 kHz wide V/U Transponder plus a 1k2 BPSK telemetry downlink. Telemetry downlink 435.800 MHz with transponder downlink 435.810-435.840 MHz, and transponder uplink 145.910-145.940 MHz. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry. *MESAT1 being prepared for integration aboard the Firefly Alpha (Photo credit, University of Maine)* MESAT1 involves three missions designed by high school students in Maine. The science payloads are climate focused and include ALBEDO, IMAGER, and HAB. These will identify urban heat islands, determine concentration of phytoplankton in water bodies, and help predict harmful algal blooms. Four multispectral cameras on board will relay the data down to University of Maine’s ground station for further processing. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry and assist in these science projects. Also deployed was *CatSat*, a technology demonstration of an inflatable antenna for high-speed communications, built by the University of Arizona. CatSat’s deployable antenna consists of a Mylar balloon. The front half of the balloon is transparent, allowing microwaves to pass through. The back half of the balloon is aluminized, creating a reflecting antenna. After reaching low Earth orbit, CatSat’s antenna will deploy and inflate to a diameter of just over one-and-a-half feet CatSat’s demonstration will be to transmit high-definition Earth photos to 10 GHz, X-band ground stations at ~50 megabits per second. *Artist’s rendering of CatSat with 10 GHz balloon antenna deployed. (University of Arizona)* In addition to images, data about the structure of the Earth’s ionosphere will be gathered by listening-in to thousands of beacons from ground-based ham radio stations. CatSat will relay WSPR and FT8 signals from HF. Downlinks on 437.185 MHz and 10470.00 MHz.

As work progressed on the network, some users encountered LoTW opening briefly during which some 6600 logs were uploaded. The logs were not processed until this weekend as we tested that the interfaces to LoTW were functioning properly. We are taking steps to help manage what will likely be a huge influx of logs. We are requesting that if you have large uploads, perhaps from contests or from a DXpedition, please wait a week or two before uploading to give LoTW a chance to catch up. We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected. Lastly, please do not call ARRL Headquarters to report issues you are having with LoTW. You can contact support at LoTW-help(a)arrl.org. Through the end of the year, you may experience planned times when LoTW will be unavailable. We have been using this time to evaluate operational and infrastructure improvements we would like to make to LoTW. Those times will be announced. We appreciate your patience as we worked through the challenges keeping LoTW from returning to service. We know the importance of LoTW to our members, and to the tens of thousands of LoTW users who are not ARRL members. LoTW, just behind QST, is our second most popular ARRL benefit.

LO-19, co-ordinated by AMSAT Argentina, the LUSAT (named after the LU amateur designation for Argentina) microsatellite was launched on the first ARIANE ASAP flight V35 with SPOT 2, on the 22 January 1990 (01:35:27 GMT) into an 780 km sun-synchronous, 98 degree inclined orbit. It carried a Digital Store and Forward packet communications transponder similar to AO-16. Downlink was AX.25 at 437.125 MHz SSB 1200 bps RC-BPSK. It is box shaped with dimensions of 213 × 230 × 230 mm, with four solar panels and weighs 13.76 kg. Long past its expected useful life, in recent years LUSAT has only been transmitting an unmodulated carrier signal. On June 29, Gustavo Carpignano, LW2DTZ, reported that recent observers had failed to detect the carrier. Gustavo declared LO-19 dead. However, on July 1, Nico Janssen, PAØDLO, reported receiving the carrier, but at a signal strength much weaker than over previous years. Nico suggested that, perhaps, the onboard power amplifier has failed. Well-equipped ground stations may wish to give a listen to test what they can hear.

But here’s an idea sure to resonate with creators, mechanical tinkerers, model builders and the kid inside us all. What about using actual LEGO bricks? Researchers ground up a 4.5-billion-year-old meteorite and used the dust to 3D print LEGO-style space bricks. They actually click together like the plastic variety, with so far only one downside: they only come in one color, grey. Universe Today Want to see some of these lunar LEGOs? LEGO will showcase the space bricks at some of its stores. Creating building materials on the Moon or Mars from the material on hand means construction materials don’t have to be transported from Earth. This would be a huge savings in launch costs because less weight would have to be boosted from Earth. A group of scientists from ESA (European Space Agency) were inspired by LEGO bricks, and with the advances in 3D printing, had the idea to print space bricks and test how they would work for construction. The only problem was that except for the Moon rocks brought back by the Apollo astronauts – which are highly guarded for scientific study only — there’s not any lunar regolith available on Earth to experiment with. But meteorite dust is a close cousin to lunar regolith. The ESA team was able to get a meteorite that was discovered in Northwest Africa in 2000 and is about 4.5 billion years old. It is made of metal grains and chondrules, similar to Moon dust. *Inspired by LEGO, ESA scientists have used dust from a meteorite to 3D-print LEGO-style ‘space bricks’ to test out construction ideas for a future Moon base. Credit: The LEGO Group* They mixed the meteorite dust with some other things, like a polymer called polylactide and regolith simulant and 3D printed bricks that mimic and behave just like LEGO bricks. While they aren’t smooth like regular LEGO bricks, ESA said the space bricks gave ESA’s space engineers the flexibility to build and test a variety of structures using this new material. “It’s no secret that real-world scientists and engineers sometimes try out ideas with LEGO bricks,” said Emmet Fletcher, Head of ESA’s Branding and Partnerships Office. “ESA’s space bricks are a great way to inspire young people and show them how play and the power of the imagination have an important role in space science, too.” “Nobody has built a structure on the Moon, so it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks,” said . ESA Science Officer Aidan Cowley. “It was both fun and useful in scientifically understanding the boundaries of these techniques.” For a list of where the lunar LEGOs will be on display worldwide, see https://www.universetoday.com/167675/lego-bricks-printed-out-of-space-dust/… The LEGO website has additional details at https://www.lego.com/en-us/aboutus/news/2024/june/lego-bricks-scientists-bu… Hopefully the lunar LEGOs will inspire both children and adults about space and to encourage them to build their own LEGO Moon bases.

Assuming that next week’s planned burn to lift the satellite to geosynchronous orbit is successful, this satellite will be re-designated as GOES-19 and will, in coming months, take over the GOES-East duties from the aging GOES-16. (See ANS 182 <https://www.amsat.org/ans-182-amsat-news-service-weekly-bulletins/> last week for more details.) + *Musk come down …* Elon Musk’s SpaceX has won a contract valued at up to $843 million to build a vehicle capable of safely deorbiting the International Space Station once the station is decommissioned in 2030. While many people have suggested raising the ISS’s orbit and turning it into a museum, the amount of fuel needed to move the approximately 420-ton station to a high enough orbit to remain stable for long durations is prohibitive. + *Blow up …* Russian Resurs-P1, an almost-six-ton defunct Earth observation satellite that stopped orbit maintenance in 2017 but continued operations until 2022, unexpectedly exploded last week into hundreds of fragments. Expected to reenter later this year, Resurs-P1 was orbiting at ~350 km, close enough to the ISS’s orbital altitude that the event forced ISS astronauts into shelter for an hour while debris was tracked. + *Or go up, come down, and blow up (unexpectedly) …* during a static fire test of the first stage of China’s close-to-finished Tianlong-3 rocket, the hold-down hardware failed to do its singular job: hold down the rocket.
