This proposal window is due to ARISS by May 19, 2024 at 11:59 PM Pacific Time. 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 2024-04-30 02:30 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 2024-04-23 04:00 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.

Yes, there actually is. Well, you will have to do some work as well in order to make it work. You can buy a TYT MD UV380 or the Retevis RT-3S (both are the same radio under different names) with or without GPS but I would recommend the GPS included models. Now comes the part where you have to do some work. You will have to install a different Firmware on the radio, called OpenGD77. Here is the relevant website with all download links and step-by-step instructions to install the Firmware: https://www.opengd77.com/viewtopic.php?f=19&t=2380 After the Firmware is installed you will be able to use the build in satellite feature which includes automatic frequency shift for the selected satellite. It also offers build in satellite tracking. Good luck Peter KC3UEP Sent with [Proton Mail](https://proton.me/) secure email.

Never heard of such a beast. You did not mention if this was for FM satellites, which I think is the case or linear satellites.FM satellites you can usually store 5 frequency pairs, where VHF stays the same and UHF will change according to AOS, TCA, LOS. Linear satellites require some tuning even if you decide to operate with only one radio (Not recommended). These sats require dual radios to work properly. 73, Adrian AA5UK On Monday, April 29, 2024 at 12:44:35 PM CDT, samuel galet via AMSAT-BB <amsat-bb(a)amsat.org> wrote: I once read there was a rare handi that automatically corrected for the doppler shift during a satellite pass.

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/ ------------------------------ AO-109 Re-enters AO-109's orbit decayed on or about April 21, 2024 after just over three years in space. Launched on January 17, 2021, as part of the ELaNa 20 mission using a LauncherOne rocket operated by Virgin Orbit, AO-109, known prior to launch as RadFxSat-2 / Fox-1E, was carried aloft by a modified Boeing 747 named "Cosmic Girl" from the Mojave Air and Space Port in California, United States. After reaching an altitude of approximately 35,000 feet (11,000 meters), the rocket was released into space. This launch, conducted under NASA's CubeSat Launch Initiative program, marked the beginning of the satellite's mission to facilitate amateur radio communications and technology research. A video of the launch can be seen on YouTube. <https://www.youtube.com/watch?v=A9FqI2ukheY> AO-109 represented the fifth iteration of the "Fox" 1U amateur radio satellites series developed by AMSAT, featuring a 30KHz linear transponder radio. After launch, AMSAT's Engineering and Operations teams listened for the expected beacon signal, but nothing was initially heard. On January 27, 2021, Brad Schumacher, W5SAT, was able to hear his weak CW signals relayed through the satellite's transponder. This was confirmed by AMSAT Engineering and Operations the next day and the satellite was designated AMSAT-OSCAR 109. Continued monitoring confirmed that the satellite was operating properly, but with an extremely low signal output. It is likely that the satellite's final power amplifier transistor failed, limiting power output to just 8 mW. Although the signal was extremely weak, the satellite was able to support QSOs by CW, FT4/8, and even SSB. Five amateur stations successfully copied the weak telemetry signal from the satellite and provided valuable data about the health of the satellite: the PI9CAM radio telescope in Dwingeloo, Netherlands, provided the bulk of the data from the satellite. WA7FWF, W7KKE, K8DP, and the AMSAT Operations team also copied telemetry. Upon being declared operational and open for amateur use, despite the limitation of its low power output, on July 20, 2021, AO-109 embarked on a mission to serve both amateur radio and technology research objectives. The final telemetry data was received on April 5, 2024 from PI9CAM and revealed that the satellite had achieved a remarkable milestone: AO-109 had set a new Fox-1 program record for processor uptime. This information was gathered by Alan Biddle, WA4SCA, who has meticulously monitored telemetry reports on a daily basis and calculated the duration of each reset, allowing for precise correlation of telemetry frames with UTC time. The Fox satellites are designed to undergo onboard computer resets triggered by factors like radiation exposure and low battery voltage. Time on these satellites is measured by counting resets plus the duration since the last reset. It is common for the Fox satellites to reset every few days or weeks, especially when passing over the South Atlantic Anomaly. However, the processor on AO-109 ran continuously from September 2023 until at least April 5, 2024, accumulating over 18 million seconds of uptime—far surpassing any other Fox satellite. Among its key payloads was the RadFx-2 experiment, a collaboration with Vanderbilt University, aimed at studying the effects of space radiation on specific SRAM types. Consistent with the Fox-1A design blueprint, AO-109 was equipped with a 2-meter whip antenna and a 70 cm whip antenna. The linear transponder module developed for AO-109 also evolved into a program to equip other CubeSats with linear transponders. Evolutions of this transponder previously flew aboard HO-107 (HuskySat-1) and the next one is scheduled to fly aboard MESAT-1 later this year. AMSAT's GOLF program will also carry this linear transponder module for VHF/UHF communications. *[ANS thanks AMSAT Operations and Engineering for the above information]* ------------------------------ AMSAT at Hamvention Hamvention is just weeks away at the Greene County Fairgrounds in Xenia, OH May 17-19, 2024! AMSAT will have our usual robust presence and after-hours activities. *Volunteer at the AMSAT Booth - (Building 1, 1007-1010 & 1107-1110)* AMSAT is actively seeking volunteers to assist with booth activities and invites enthusiasts to dedicate their time. Last year, around 20 volunteers played crucial roles in fostering meaningful interactions with attendees. Volunteers, whether able to commit a few hours or the entire weekend, are warmly encouraged to participate. Aligned with this year's theme of "Expanding our Community," AMSAT aims to strengthen its presence by recruiting new members and volunteers. For those eager to be part of AMSAT's presence at Dayton Hamvention or request more information about volunteering, Phil Smith, W1EME, AMSAT Hamvention Team Leader, serves as the point of contact. To volunteer or inquire further, individuals can reach out to Phil via email at w1eme [at] amsat.org.

Tickets purchased on-line will be maintained on a list with check-in at the door at the banquet center. Seating is limited to the number of meals reserved with the Kohler caterers based on the number of tickets sold by the deadline. *[ANS thanks the AMSAT Hamvention Team for the above information]* ------------------------------ Robusta-3A With Store & Forward Repeater Scheduled for Launch Robusta-3A is a 3U CubeSat with multiple mission 1) Amateur: Store & forward repeater, refer to 5.5 paragraph for more details. 2) Educational: No less than 300 students participated in the development of the platform. As part of their training, a module is allocated to the initiation to amateur radio. In addition, we pass the license to around ten students each year with the ANFR (French administration) and 3 new operators at CSUM. 3) Technical validation mission: An S-band transmitter is on board operating in commercial band for test purposes. This payload will not be controlled by the amateur radio band. The HAM radio messaging system provides a message-exchanging service between amateur radio users using Robusta satellite missions as relays. The main purpose of the system is to enable HAM radio operators to send and receive messages from anywhere in the world without having a direct (end-to-end) connection between them. The messaging system uses a method called ‘store and forward’ to provide this service. Messages are transported to the relay station (satellite) by a radio link, and from one geographical location to another, by the satellite orbital movement. A user sends a message to the satellite during a pass and the message is stored in the satellite’s memory. The satellite then moves on its orbit, making the stored message available for other HAM radio operators. Users can request messages to the satellite which, in turn will check if there are any stored messages available for that particular operator. Finally, the message is transmitted and it arrives at its destination A UHF downlink using 9k6 GMSK with AX25 is proposed. Launch is planned on the Ariane 6 maiden flight from Kourou, French Guiana into a 580 km circular 96 degree orbit together with GRBBEta and ISTSAT.

ARISS News Release No. 24-27 DaveJordan, AA4KN ARISS PR aa4kn(a)amsat.org FORIMMEDIATE RELEASE ARISSContact is Scheduled with Students at Centennial Campus Magnet Middle School Center forInnovation, Raleigh, North Carolina, USA April 27, 2024—AmateurRadio on the International Space Station (ARISS) has received scheduleconfirmation for an ARISS radio contact between an astronaut aboard theInternational Space Station (ISS) and students at the Centennial Campus MagnetMiddle School Center for Innovation located in Raleigh, NC. ARISS conducts 60-100 of these specialamateur radio contacts each year between students around the globe and crewmembers with ham radio licenses aboard the ISS. CentennialCampus Center for Innovation Magnet Middle School is a 6th through 8th gradepublic school serving approximately 470 students. As a Center for Innovation, students workwith STEM learning and the Design Thinking process to develop those skill setsand characteristics of an Innovator and thus are preparing for careers not yetimagined. In anticipation of this ARISS contact, students have learned aboutthe ISS and have taken a virtual tour of the ISS. Students have also participatedin various design thinking challenges, including designing a moon lander - ashock absorbing system that will protect two astronauts (marshmallows) whenlanding on the moon (dropped from a height). This will be atelebridge Contact via AmateurRadio allowing students toask their questions of astronaut Matthew Dominick, amateur radio call sign KCØTOR.The downlink frequency for this contact is 145.800 MHz and may be heard bylisteners that are within the ISS-footprint that also encompasses thetelebridge station. The ARISS amateur radio ground station (telebridge station)for this contact is in Greenbelt, Maryland, U.S. The amateur radio volunteerteam at the ground station will use the callsign K6DUE, to establish andmaintain the ISS connection. The ARISS radiocontact is scheduled for May 1, 2024 at 8:03:49 am EDT (NC) (12:03:49 UTC, 7:03am CDT, 6:03 am MDT, 5:03 am PDT). The public isinvited to watch the live stream at: https://youtube.com/live/4ZU7I208cw4 _______________________________ As time allows,students will ask these questions: 1. What is thelimit for how long someone can stay in space? How long have you been in space? 2. What is thebiggest challenge you face in your daily life aboard the ISS? 3. What doescollaboration with your fellow crew members look like on board the ISS? 4. What is thehardest part about being an astronaut, and how to you maintain a positiveattitude? 5. How does itfeel when you come back down to earth? Does it feel weird because of thedifference of gravity? 6. How manyyears did you have to study to become an astronaut and what do you study? 7. When do youuse resilience on your job? How do you stay motivated when working on difficulttasks? 8. Could you see the eclipse from the ISS? Whatother space events can you see from the ISS (like the eclipse) that we may nothave thought about? 9. We focus onthe Design Thinking process to solve problems. What process do you use to solveproblems? 10. How longdid it take you to feel like you were at home? Or what would make you feel moreat home? 11. What issome advice you would give to students willing to follow your career path? 12. What is anunderrated/not really known part of your job? 13. What typeof science projects are you working on? 14.

How do youprepare for emergencies on the ISS? For example, do you have fire drills? 17. What foodsare you able to grow in space? 18. How often do you work with astronauts fromother countries? Can you describe what that is like and what challenges you mayface? 19. Have youever had any ventilation problems on the ISS, if so what did you do to fix it? 20. What wasthe process you went through to adjust to zero gravity? How does that feel? About ARISS: Amateur Radio on the International Space Station (ARISS) isa cooperative venture of international amateur radio societies and the spaceagencies that support the ISS. In the United States, sponsors are the AmericanRadio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), RadioAmateur Satellite Corporation (AMSAT), NASA’s Space Communications andNavigation program (SCaN) and the ISS National Lab—Space Station Explorers. Theprimary goal of ARISS is to promote exploration of science, technology,engineering, the arts, and mathematics topics. ARISS does this by organizingscheduled contacts via amateur radio between crew members aboard the ISS andstudents. Before and during these radio contacts, students, educators, parents,and communities take part in hands-on learning activities tied to space, spacetechnologies, and amateur radio.

(***) 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 2024-04-23 04:00 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.

Upcoming ARISS Contact Schedule as of 2024-04-24 03:00 UTC Quick list of scheduled contacts and events: Centennial Campus Magnet Middle School Center for Innovation, Raleigh, NC, telebridge via K6DUE(***) 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 AA6TB Contact is go for: Wed 2024-05-01 12:03:49 UTC 76 deg (***) Watch for Livestream at: https://youtube.com/live/4ZU7I208cw4 Wireless Institute of Australia / Bundaberg High School Amateur Radio Club, Bundaberg, Queensland, Australia, telebridge via VK6MJ 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 VK4KHZ Contact is go for: Sat 2024-05-04 10:28:24 UTC 51 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 2024-04-24 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 2024-04-23 04:00 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.

Two Inexpensive Shack Enhancements

Two items that have thoroughly enhanced my enjoyment of this hobby the past few years: An RTL-SDR Dongle, and the Inovato HamClock System. And either will just set you back $50. The RTL-SDR dongle will turn your computer, phone or tablet into a radio scanner/ham radio receiver that can receive nearly all RF signals. And is compatible with Windows, Mac OS, Linux, and Android. Here is a non-affiliate link to a popular kit on Amazon - https://a.co/d/8F2nSQn And I think I've written about the Inovato HamClock setup before. For $50, The Inovato Quadra PC bundle features the fantastic HamClock by Elwood Downey. Gives you all the essentials you need to run HamClock (will always auto-update to the latest) on your 1080p or higher resolution TV or monitor. This kit INCLUDES the Quadra PC, HDMI cable, ham-friendly USB power adapter, custom stand, a quiet fan with a short cable, and a USB hub for a neat, small-footprint and cooler-running installation. Just add your own keyboard/mouse if you don't purchase their +$10 mini-keyboard. The Quadra PC that you receive also has more ham-related programs pre-installed. It's Debian/Linux XFCE - a "Pi-like" experience. But you do not need to know ANY programming skills to get up and running.

Support the CubeSat History Project
by Aaron Zucherman 22 Apr '24

22 Apr '24

Good day AMSAT community! We have an update for the Community on the progress of the CubeSat History Project! For those unfamiliar, Prof. Robert "Bob" Twiggs and a group of former students and colleagues are working on gathering and publishing a series of books on the history of the creation and adoption of the CubeSat. Take a look at the LinkedIn announcement here: https://lnkd.in/eNZgv6Tk If this sounds like something you'd be interested in supporting, please take a look at our GoFundMe page here: https://www.gofundme.com/f/cubesat-history-project The community's response has been amazing! Over a hundred interviews were conducted, and countless images and documents from the earliest days of the CubeSat were collected! The result is that we have accumulated one of the most comprehensive histories of the CubeSat, with many unique, never-before-told stories! Reach out if you are interested in sponsoring the project to get a signed copy and your organization's name in the book. Please email Dr. Aaron Zucherman at azucherman(a)gmail.com. As a bonus, please have a look at our book's cover art! [image: image.png] On behalf of Prof. Robert Twiggs and the entire team, Thank you for supporting our mission!

And be careful using longer/heavier antennas on your delicate SMA connector. Consider a adapter to make that SMA a BNC. I'd rather see you wear out a $15 adapter, then tear the center pin connection off the circuit board of your radio, requiring a radio replacement or a $60 repair job. High-quality SMA connectors are only rated at 3 to 500 connections, and lesser-expensive radios are not using high-quality SMA connectors.

A single whip is obviously a compromise. The Smiley is a tri-band, but with specific whip extensions for specific bands. The 70 CM and the 2M lengths are different so there will be a compromise on the band that is not the band the antenna is set up for. I would probably have to make a decision as to whether to set this type of antenna for the RX band or the TX band. Resonance on TX means more power transferred to the antenna. Resonance on the RX band means better reception at the expense of RF out (Radio power foldback if SWR is too high).

Mark, Space-Track has a prediction for today, but not more specific. They seldom issue a final report of CubeSats though they will stop issuing new Keps. So, we need to use inference. Given the weak beacon, that is even trickier. Using the latest Keps, it should reenter around now, but with a wide range of time. One strong indicator is from the Status Page. EA6TA has regularly been reporting it was heard for the past few days. Today around 1430 UTC, he reported it was not heard. So it is likely down, or at the very least rendered inoperative by heat.

Have the HT already-a 10 watt TIDRADIO HT and have made a couple of satellite QSOs using its stock rubber duck. I bought a Nagoya 771R telescoping version of their 771 antenna (which everyone raves about) but it doesn't hear the Mode J satellites well. The stock rubber duck hears them better. The antenna is supposed to be a 5/8 wave on 70cm, maybe that is the problem. Any recommendation on HT antennas people have been using on the satellites with success? It needs to be a whip type antenna-not a yagi that breaks down for transportation. I realize this is a very limited setup, but it is better than being QRT in some circumstances. 73 John AF5CC Sent using {0}

A total of 9 of the submitted proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS. The primary goal of the ARISS program is to engage young people in Science, Technology, Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities. [ARISS News] The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the 9 US host organizations during the July – December 2024 time period. They are now at work starting to implement their 4–6-month education plan which was outlined in their proposal. These STEAM based educational activities help prepare students for their contact as well as create an on-going exploration and interest in aerospace and amateur radio topics. They are also completing an acceptable equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by ARISS, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA. The schools and host organizations are: * Arizona Science Center, Phoenix, AZ * Bayou Academy, Cleveland, MS * Bishop O’Connell High School, Arlington, VA * Greenville Junior High School, Greenville, IL * Hillsboro Charter Academy, Purcellville, VA * Pacific Science Center, Seattle, WA * Sally Ride Elementary School, Orlando, FL * South Carolina Regional Workforce Advisors-Office of Statewide Workforce Development, Columbia, SC * TEACH-NW Charter School, Springfield, OR [ANS thanks Dave Jordan, AA4KN, for the above information.] ________________________________ [cid:[email protected]] The 2024 AMSAT President’s Club coins are here now! 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/ ________________________________ AMSAT Thanks First Quarter 2024 President’s Club Members Frank Karnauskas, N1UW, AMSAT VP – Development happily reports, “Each year for the past four years of its re-incarnation, the AMSAT President’s Club has picked up speed and becomes a more important factor in AMSAT’s annual fund raising efforts. The first quarter of the 2024 the President’s Club is off to a great start. With our regular dedicated contributors plus many first-time members, contributions have already raised almost $16,000 in the first three months of 2024. “So often, our members think about AMSAT’s having to raise funds for satellite hardware – the costs for electronic components, solar panels, batteries and so on. But, there are many background costs. A good example is software licenses needed for actual satellite development. The volunteer engineers can often swap licenses so they can limit the number of licenses needed. But, as they draw closer to finalizing drawings for circuit boards, spaceframes and deployable solar panels, the team can stretch software licenses only so far before work flow becomes handicapped. Some software licenses, even with the best educational or non-profit discounts, easily exceed the $1,000 mark. And, those licenses need to be renewed on an annual basis. “The engineering team can always use more electrical and mechanical engineers to move the FOX-PLUS and GOLF programs along. But, being able to leverage the efforts of our current volunteers with enough software licenses would be a huge plus. Contributions from members of the President’s Club make a big difference in giving the engineering team the tools they need.” To date, the generous donors members of the 2024 AMSAT President’s Club include: * Titanium ($4,800+) Barry Baines, WD4ASW William Brown, K9LF * Gold ($1,200+) Anonymous Burns Fisher, WB1FJ John Kludt, K7SYS Glenn Miller, AA5PK * Silver ($600+) Donald Coker, KM6TRZ Richard Dittmer, KB7SAT Mark Johns, K0JM Joseph, Lynch,N6CL Bruce Paige, KK5DO Jason Schwarz, N4JJS * Bronze ($300+) Donald Pettigrew, K9ECT Dave Taylor, W8AAS * Core ($120+) David Batzle, N2VDY Robert Beatty, WB4SON Alan Boggs, K7IIV James Gallagher III, KB3SQS David Hartrum, WA3YDZ Steven Husey, KB1UOJ William Pesci, N4WLP Paul Stoetzer, N8HM Stefan Wagener, VE4SW Wayne Wagner, AG1A Members can learn more about joining the President’s Club at https://www.amsat.org/join-the-amsat-presidents-club/.

Not wanting to disappoint our members, Jerry Buxton, N0JY, AMSAT VP- Engineering and his team are making plans for an informative and entertaining presence. No fewer than ten members of the engineering team will attending this year’s Hamvention. Probably the most interesting exhibit will be a full-scale model of the GOLF-TEE (Technology Exploration Environment) satellite. The 3-D model printed by team member Tom Karnauskas, N0UW, gives an interesting look at the challenges that satellite designers face when trying to fit stacks of circuit boards, bundles of batteries, attitude sensing and control systems, and experimental payloads inside a 10cm x 10cm x 30cm spaceframe. The model also gives a look at the challenge of adding deployable solar panels to the exterior of the spacecraft. Given the fact that the GOLF program represents AMSAT’s return to Highly Elliptical Orbit (HEO), engineers will no-doubt be busy answering questions on all facets of the GOLF program. Engineers will also be on hand to answer questions about the ongoing development of the Fox-Plus series of satellites. Recognizing the success of the original Fox series as an entry level introduction to amateur satellites, the engineers working the Fox-Plus birds are committed to improving on the original concept and setting the stage for future capabilities for these Low Earth Orbit (LEO) satellites. For those interested in a look even further into the future, engineers working the ASCENT program will also be present. ASCENT, meaning, Advanced Satellite Communication and Exploration of New Technology, is a “sandbox” for future satellite communications and related systems to be explored and pursued for eventual flight use. A radiation-tolerant internal-housekeeping-unit (RT-IHU), software defined radio (SDR) methods, and a 10 GHz PA design ideas are some ASCENT projects that will fly on GOLF-TEE. Engineers at the table can also discuss other ASCENT projects in the works such as a slow-scan television (SSTV) payload, a packet repeater payload and propulsion systems suitable for CubeSat operation.

More information on the workshop can be found at https://www.cubesatdw.org/. [ANS thanks cubesat.org for the above information.] * AMSAT-DL has announced planning for the Bochum Space Conference 2024 to be held September 20-22, 2024. AMSAT-DL is organizing a symposium, flea market and general meeting in the radome of the Bochum Observatory. The radome will once again be dedicated to satellite and space research. AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive experience of the anniversary conference in 2023 as an opportunity to inform AMSAT members and other space enthusiasts about current and future prospects for national and international space projects with a varied program. As the Radom is also the location of ESA’s education office in Germany (esero Germany), they want to make the symposium even more attractive in future and at the same time focus even more on current European space travel. More information at https://amsat-dl.org/en/bochum-space-conference-2024/. [ANS thanks AMSAT-DL for the above information.] * Boeing’s CST-100 Starliner embarked on its last big road trip before its journey to the International Space Station next month. In the pre-dawn hours of Tuesday morning, the capsule and its service module made the slow trek from Kennedy Space Center to Space Launch Complex 41 on Cape Canaveral Space Force Station. The rollout of the vehicle, named Calypso, is another key step towards the Crew Flight Test (CFT) of the Starliner spacecraft, the first time that it will carry astronauts to and from the ISS. The mission’s crew, NASA astronauts Butch Wilmore and Suni Williams, KD5PLB, were on hand to witness the departure of their ticket to ride. [ANS thanks Spaceflight Now for the above information.] * A dead spacecraft the size of a truck ignites with plasma and pulverizes into dust and litter as it rips through the ionosphere and atmosphere. This is what happens to internet service satellites during re-entry. When the full mega-constellation of satellites is deployed in the 2030s, companies will do this every hour because satellite internet requires thousands of satellites to constantly be replaced. Recent research has led some physicists to believe that the space trash generated by dead and dying commercial satellites could compromise our ionosphere or magnetosphere. Unlike meteorites, which are small and only contain trace amounts of aluminum, these wrecked spacecraft are huge and consist entirely of aluminum and other exotic, highly conductive materials. And highly conductive materials can create charging effects and act as a magnetic shield.

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 2024-04-19 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 2024-04-19 04:00 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.
