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. Have youever worked with others in the station on a collaborative project? If so, howdid you collaborate as a team? 15. How doastronauts prepare for a journey to space? 16. 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.

Two “different” audiences last week invited me to speak. The Mount Baker Amateur Radio Club in Bellingham, WA, was a ham club - and we had a great time. But the Orange County (CA) Astronomers Club was a little, well, different. But there was plenty of “crossover” interests: space photography, studies of our planets … so it wasn’t a 100-percent “ham” audience.

(***) 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. 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.

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. 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.
