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.

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.

AMSAT Ambassador Clint Bradford, K6LCS, says, "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. But I edited and came up with a presentation they said they enjoyed!" "Think a 75-minute presentation on "working the easy satellites" would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!" Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences. Scheduled Events *Dayton Hamvention 2024* Friday May 17th through Sunday May 19th, 2024 Greene County Fairgrounds and Expo Center 120 Fairground Road Xenia, OH 45385 https://hamvention.org *[ANS thanks Clint Bradford, K6LCS, and AMSAT for the above information]* ------------------------------ Satellite Shorts from All Over + David Bowman, G0MRF, and Graham Shirville, G3VZV, will travel to St. Johns, Newfoundland May 15-19, 2024 in an attempt to operate QO-100 from below the horizon and claim trophies sponsored by AMSAT-UK and the British Amateur Television Club for the first QO-100 QSOs from North America. AMSAT-UK and BATC posed the challenge <https://amsat-uk.org/2022/11/01/making-qo-100-contacts-from-north-america-a…> in 2022. The trophies have so far gone unclaimed, though successful below horizon operation on QO-100 has occurred from Indonesia. (ANS thanks David Bowman, G0MRF, for the above information) + Members of the AMSAT Engineering team attended the CubeSat Developer's Workshop in San Luis Obispo, CA this past week. The workshop offered an opportunity for AMSAT Engineers to network with other CubeSat developers and learn about the most recent developments in space technology as applied to CubeSats. + The U.S. space agency says its Voyager-1 probe is once again sending usable information back to Earth after months of spouting gibberish. The 46-year-old NASA spacecraft is humanity's most distant object. A computer fault stopped it returning readable data in November but engineers have now fixed this. For the moment, Voyager is sending back only health data about its onboard systems, but further work should get the scientific instruments back online. Voyager-1 is more than 24 billion km (15 billion miles) away, so distant, its radio messages take a full 22.5 hours to reach us. (ANS thanks BBC News for the above information.) + In Colorado Springs, Colorado, students at the Thrive Home School Academy <https://www.thrivehsa.org/> (THSA), along with students at Stratton Meadows Elementary (SME), were able to have a space chat with NASA astronaut and mission specialist Jeanette "Jo" Epps, KF5QNU, on board the International Space Station (ISS) on April 22, 2024. At the time of the contact Epps, a member of the SpaceX Crew-8 mission, was on her 47th day of the 180-day mission.

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/.

[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/ ________________________________ AMSAT Engineering Team Powering Up for Hamvention Given hams’ inherent interest in all things technical, it’s no wonder that the Engineering table at AMSAT’s Hamvention booth is always popular. 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.

[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.

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 we want to make sure that critical parts of space are preserved so that our children and grandchildren can continue to use them for the benefit of humanity, the time to act is now. NASA is making sure that we’re aligning our resources to support sustainable activity for us and for all.” For decades, NASA has served as a proactive leader for responsible and sustainable space operations. Entities across the agency develop best practices, analytic tools, and technologies widely adopted by operators around the world. The new strategy seeks to integrate those efforts through a whole-of-agency approach – allowing NASA to focus its resources on the most pressing issues. To facilitate that integration, NASA will appoint a new director of space sustainability to coordinate activities across the agency. Key aspects of our approach include providing global leadership in space sustainability, supporting equitable access to space, and ensuring NASA’s missions and operations enhance space sustainability. Space environments currently are seeing the rapid emergence of commercial capabilities, many of them championed by NASA. These capabilities include increased low Earth orbit satellite activity and plans for the use of satellite constellations, autonomous spacecraft, and commercial space destinations. However, this increased activity also has generated challenges, such as an operating environment more crowded with spacecraft and increased debris. Understanding the risks and benefits associated with this growth is crucial for space sustainability. Developed under the leadership of a crossagency advisory board, the space sustainability strategy focuses on advancements NASA can make toward measuring and assessing space sustainability in Earth orbit, identifying cost-effective ways to meet sustainability targets, incentivizing the adoption of sustainable practices through technology and policy development, and increasing efforts to share and receive information with the rest of the global space community. NASA’s approach to space sustainability recognizes four operational domains: Earth, Earth orbit, the orbital area near and around the Moon known as cislunar space, and deep space, including other celestial bodies. The first volume of the strategy focuses on sustainability in Earth orbit. NASA plans to produce additional volumes focusing on the other domains.

Otero wasn’t home at the time. A Nest home security camera captured the sound of the crash at 2:34 pm local time (19:34 UTC) on March 8. That’s an important piece of information because it is a close match for the time—2:29 pm EST (19:29 UTC)—that US Space Command recorded the reentry of a piece of space debris from the space station. At that time, the object was on a path over the Gulf of Mexico, heading toward southwest Florida. *In all likelihood, this nearly 2-pound object came from the International Space Station. Otero said it tore through the roof and both floors of his two-story house in Naples, Florida. (Photo by Alejandro Otero on X) * This space junk consisted of depleted batteries from the ISS, attached to a cargo pallet that was originally supposed to come back to Earth in a controlled manner. But a series of delays meant this cargo pallet missed its ride back to Earth, so NASA jettisoned the batteries from the space station in 2021 to head for an unguided reentry. NASA has recovered the debris from the homeowner, according to Josh Finch, an agency spokesperson. Engineers at NASA’s Kennedy Space Center will analyze the object “as soon as possible to determine its origin,” Finch told Ars. “More information will be available once the analysis is complete.” The entire pallet, including the nine disused batteries from the space station’s power system, had a mass of more than 2.6 metric tons (5,800 pounds), according to NASA. Size-wise, it was about twice as tall as a standard kitchen refrigerator. It’s important to note that objects of this mass, or larger, regularly fall to Earth on guided trajectories, but they’re usually failed satellites or spent rocket stages left in orbit after completing their missions. In a post on X, Otero said he is waiting for communication from “the responsible agencies” to resolve the cost of damages to his home. If the object is owned by NASA, Otero or his insurance company could make a claim against the federal government under the Federal Tort Claims Act, according to Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi. “It gets more interesting if this material is discovered to be not originally from the United States,” she told Ars. “If it is a human-made space object which was launched into space by another country, which caused damage on Earth, that country would be absolutely liable to the homeowner for the damage caused.” This could be an issue in this case. The batteries were owned by NASA, but they were attached to a pallet structure launched by Japan’s space agency. NASA typically doesn’t want large chunks of space debris falling to Earth with an uncontrolled reentry. You can trace the reason this object came down unguided back to a Russian launch failure more than five years ago. NASA astronaut Nick Hague and Russian commander Alexey Ovchinin aborted their launch on a Soyuz spacecraft when their rocket failed shortly after liftoff. One of Hague’s jobs at the International Space Station would have been to go outside on spacewalks to help install a new set of lithium-ion batteries recently delivered by a Japanese HTV cargo ship. But Hague didn’t reach the station in 2018, so NASA put off the spacewalks until a new team of astronauts arrived at the complex. This interruption to the space station’s carefully choreographed schedule threw off the entire multiyear plan for upgrading the batteries on the outpost’s electrical system. Instead of putting the old batteries back into the HTV for a guided destructive reentry over the open ocean, NASA held onto the cargo pallet at the station when the HTV supply ship needed to depart. Each of the subsequent HTV missions delivered more fresh batteries to the space station and then departed the complex with the cargo pallet and decommissioned batteries from the previous HTV mission. That was the case until there were no more HTVs to fly. Japan’s last HTV spacecraft departed the ISS in 2020 with the cargo pallet and batteries from the prior flight, stranding the last battery pallet at the station. The space station’s other cargo vehicles—SpaceX’s Dragon, Northrop Grumman’s Cygnus, and the Russian Progress—can’t accommodate the HTV cargo pallet. So NASA decided to jettison the battery pallet using the space station’s robotic arm in March 2021 in order to free up real estate on the lab. Without any propulsion of their own, the batteries were adrift in orbit for three years until aerodynamic drag finally pulled the pallet back into the atmosphere on March 8, almost exactly three years later. It is notoriously difficult to predict where a piece of space junk will reenter the atmosphere. US Space Command precisely tracks tens of thousands of objects in Earth orbit, but the exact density of the upper atmosphere is still largely an unknown variable. Even a half-day before the reentry, US Space Command’s estimate for when the battery pallet would fall to Earth had a window of uncertainty spanning six hours, enough time for the object to circle the planet four times. And if you don’t know when something will reenter the atmosphere, you can’t predict where it will come down. If NASA confirms the projectile that fell through Otero’s house last month came from the ISS, it would join a small handful of incidents when an object falling out of orbit damaged someone’s property. Earth is a big place. It’s fairly common for someone to find a piece of fallen space junk in a field or washed up on a beach. But it is rare for a reentry to hit a structure or injure a person. Falling space debris has never killed anyone. According to ESA, the annual risk of an individual human being injured by space debris is less than 1 in 100 billion.

The Heavy’s three hydrogen-fueled RS-68A first stage engines ignited with a rush of bright orange flame at 12:53 p.m. EDT, smoothly pushing the 235-foot-tall rocket away from pad 37 at the Cape Canaveral Space Force Station in Florida. *The last Delta 4 Heavy rocket climbs away from the Cape Canaveral Space Force Station on April 9, 2024, carrying a classified National Reconnaissance Office spy satellite. (United Launch Alliance photo.)* The launch came 12 days late, primarily because of work to replace a pump in a system that supplies nitrogen gas to multiple launch pads from a pipeline running through the Kennedy Space Center and the Cape Canaveral Space Force Station. There were no problems Tuesday. Mounted atop the rocket was a classified satellite provided by the National Reconnaissance Office, the secretive government agency that manages the nation’s fleet of sophisticated optical and radar imaging reconnaissance satellites and electronic eavesdropping stations. In keeping with standard NRO-U.S. Space Force policy for such missions, no details about the NROL-70 payload were released. But about six hours after launch, the National Reconnaissance Office declared the launch a success, indicating the satellite reached its planned orbit.The final appearance of a Delta rocket 63 years after the first variant’s maiden flight was an emotional milestone for the managers, engineers and technicians who assembled and launched the last member of the family. The Delta family of stages and rockets had its roots in the early space program, first serving in the nation’s fleet of intermediate-range ballistic missiles and evolving through multiple versions used to put military, NASA and civilian payloads into orbit. The now-retired Delta 2 debuted in 1990, putting the first Global Positioning System satellites into orbit and sending multiple planetary probes into deep space, including Messenger to Mercury, multiple Mars orbiters, the Pathfinder, Spirit and Opportunity Mars rovers, the Spitzer Space Telescope and many more. The single-core Delta 4 first flew in 2002 with the first Heavy following two years later. The single-core version flew the program’s final flight in 2019. Tuesday’s launch was the 45th flight of a Delta 4 and the 16th and final Delta 4 Heavy. “Launching the last Delta 4 is bittersweet for me,” Col. Eric Zarybnisky, director of NRO’s Office of Space Launch, said in a statement. “I was part of the team that launched the first Delta 4 for the NRO. Since that time, the Delta 4 has put amazing capability on orbit for this nation.” Tory Bruno, president and CEO of United Launch Alliance, also called the flight a “bittersweet” moment as the company continues its transition to next-generation Vulcan rockets, phasing out its more expensive Delta and Atlas families. “Soon, Vulcan will pick up that mantle and we’re going to retire this venerable rocket that has made so much important work for our country,” he said after launch in a pre-recorded video.

Unfortunately, one of Voyager 1’s FDS memory chips is malfunctioning—NASA hopes they can work around it, but it will likely take months.(ANS thanks The Orbital Index for the above information.) + If you have 26 minutes to spare, and want to explore more intricacies of Ohm’s Law than you were taught in school, watch electricity flow through a wire a nanosecond at a time at https://www.youtube.com/watch?v=2AXv49dDQJw (ANS thanks The Orbital Index for the above information.) + Following repairs to a liquid oxygen leak in the Falcon Heavy’s core booster, NASA and SpaceX have rescheduled the launch of the GOES-U satellite, the final installment in NOAA’s GOES-R Series, for June 25. The adjustment aims to ensure thorough examination and resolution of the issue, discovered during a routine inspection in February. With preparations now back on track, the deployment of GOES-U from Kennedy Space Center’s Launch Complex 39A will proceed using a SpaceX Falcon Heavy rocket. Managed cooperatively by NOAA and NASA, the GOES-R Series Program encompasses satellite operations, data dissemination, and ground systems oversight, with NASA’s Goddard Space Flight Center leading spacecraft acquisition and instrument development. Lockheed Martin’s contributions include design, construction, and testing of the satellites, while L3Harris Technologies has provided key instruments and ground systems essential for capturing atmospheric observations. (ANS thanks Clarence Oxford, SpaceDaily, for the above information) + The European Union is poised to finalize a security deal with the United States, enabling payments to Elon Musk’s SpaceX for satellite launches due to delays in Europe’s Ariane rocket system. Approved by national general affairs ministers, the agreement grants European Union and European Space Agency (ESA) personnel continuous access to launch facilities and prioritized debris retrieval rights in case of SpaceX rocket failures. With a 200 million deal already struck last year, SpaceX is contracted to launch four Galileo satellites as Ariane 6 faces further delays. While Ariane 6 is slated for a summer launch, commercial missions await later scheduling. The arrangement with SpaceX allows for two Galileo satellite launches this year, necessitated by Soyuz launcher cancellations and Ariane 6 delays. The security pact ensures access to classified Galileo equipment, with provisions for debris retrieval and a sunset clause by 2027 to address concerns about reliance on SpaceX over Ariane.

The agency has until the end of 2026 to set up LTC, which is not akin to Earth’s time zones but provides a frame of time reference for the moon. LTC will accommodate the slightly faster passage of time on the moon, approximately 58.7 microseconds each day compared to Earth, due to its lower gravity. It will serve as a benchmark for timekeeping for lunar spacecraft and satellites, crucial for their missions. NASA’s Artemis program, set to begin astronaut missions to the lunar surface in 2026, necessitates LTC for synchronization among Earth, lunar satellites, bases, and astronauts, without which data transfers and communications could be compromised. Developing LTC will require international agreements, possibly influenced by the Universal Coordinated Time (UTC) standard, with potential implementation involving atomic clocks on the moon and adherence to existing space agreements like the Artemis accords.

Launched in January 2021, this satellite operates with an 8 mW signal, best suited for CW and FT4 communications among amateur radio enthusiasts. Recent telemetry data from the Dwingeloo Radiotelescope in The Netherlands has revealed an impressive feat: AO-109 has set a new 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 has been running continuously since September 2023, accumulating over 18 million seconds of uptime-far surpassing any other Fox satellite. Launched on January 17, 2021, as part of the ELaNa 20 mission using a LauncherOne rocket operated by Virgin Orbit, AO-109 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. [https://www.amsat.org/wordpress/wp-content/uploads/2024/04/AO-109_FOX-1E.jpg]<https://www.amsat.org/wordpress/wp-content/uploads/2024/04/AO-109_FOX-1E.jpg> AO-109 (Fox-1E) Satellite is Expected to Re-enter Earth's Atmosphere in April 2024. [Credit: AMSAT] AO-109 represents the fifth iteration of the "Fox" 1U amateur radio satellites series developed by AMSAT, featuring a 30KHz linear transponder radio. Upon becoming operational on July 20, 2021, AO-109 embarked on a mission to serve both amateur radio and technology research objectives. Among its key payloads is RadFXSat-2, a collaboration with Vanderbilt University, aimed at studying the effects of space radiation on specific SRAM types. Consistent with the Fox 1A design blueprint, Fox-1E is equipped with a 2-meter whip antenna and a 70 cm whip antenna. With its anticipated re-entry into Earth's atmosphere in the coming weeks, users are encouraged to make the most of AO-109 while it's still operational. Current reports suggest the satellite's altitude is around 300 km, which is lower than the ISS orbiting altitude of 370-460 km.

Help Support GOLF and Fox Plus [https://www.amsat.org/wordpress/wp-content/uploads/2024/01/2024-Coin-Both_5…] Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ________________________________ ESA Unveils Proba-3 Mission: Artificial Solar Eclipses on Demand Next week, a celestial spectacle will unfold across North America as millions of people witness a total solar eclipse. Alongside eager spectators, solar physicists worldwide are gearing up for the event, drawn by the opportunity to study the Sun's enigmatic corona, typically obscured by its intense luminosity. However, thanks to a innovative initiative by the European Space Agency (ESA), sustained examination of the solar corona will soon become feasible through the Proba-3 mission. In Belgium last week, the European Space Agency revealed the spacecraft pair which constitute the Proba-3 mission. This initiative aims to generate orbital solar eclipses at will, providing researchers with extended periods to scrutinize the Sun's ethereal corona. The mission comprises two spacecraft: the Occulter and the Coronagraph. Positioned approximately 150 meters apart, these spacecraft will align meticulously with the Sun, with the Occulter casting a shadow onto the Coronagraph, effectively blocking out the Sun's glare and unveiling the corona. Dietmar Pilz, ESA's Director of Technology, Engineering, and Quality, explains, "The two spacecraft will act as if they are one enormous 150-meter-long instrument." However, achieving such precision poses immense technical challenges. Even the slightest misalignment could disrupt the mission's efficacy. Consequently, the development process, spearheaded by a consortium of ESA Member States led by Spain and Belgium, has been extensive. [https://www.amsat.org/wordpress/wp-content/uploads/2024/04/Proba-3_Satellit…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/04/Proba-3_Satellit…> Rendering of Proba-3 Occulter and Coronagraph Spacecraft above Earth [Credit: European Space Agency] The fundamental concept of generating artificial solar eclipses in orbit isn't novel. Previous attempts, such as the Apollo-Soyuz Test Project in 1975, have explored similar endeavors. However, Proba-3 seeks to institutionalize this capability through precise formation flying, enabling up to six hours of continuous observation per orbit lasting 19 hours and 36 minutes. Solar eclipses, a consequence of the fortunate alignment of the Sun and the Moon, unveil the solar corona - a region of profound scientific and practical significance. Significantly hotter than the Sun's surface, the corona influences space weather, solar wind, and phenomena like coronal mass ejections, which can impact satellite operations and terrestrial communications networks. Proba-3's groundbreaking approach involves orchestrating the Occulter and Coronagraph to operate as a unified entity, thus minimizing diffraction effects and maximizing the observation of the corona. This collaboration, facilitated by advanced positioning technologies, promises to unveil the mysteries of the corona within the range of 3 to 1.1 solar radii from the Sun. [https://www.amsat.org/wordpress/wp-content/uploads/2024/04/Proba-3_Occulter…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/04/Proba-3_Occulter…> Occulter and Coronagraph Spacecraft Undergoing Integration Testing at Redwire's Belgium Facility [Credit: ESA] The mission's autonomy is paramount, with precise formation flying orchestrated autonomously to minimize external perturbations. This autonomy enables the spacecraft to maintain precise alignment for optimal observation of the corona while passively drifting during the remainder of the orbit. Beyond its scientific implications, the success of Proba-3 could herald a new era of space missions, facilitating endeavors like in-orbit satellite servicing and deploying larger-scale space infrastructure. Moreover, the mission's instruments, like ASPIICS and the radiometer, hold promise for climate modeling and advancing our understanding of solar dynamics. As the world awaits the North American total solar eclipse, members of Proba-3's science team seize the opportunity to test mission hardware. Components like polarizing filter wheels and alternative LED technologies will undergo rigorous examination, further refining the mission's capabilities.

The project, named Atmospheric Perturbations Around The Eclipse Path (APEP), aims to investigate how the sudden drop in sunlight and temperature during the eclipse affects Earth's upper atmosphere. Named after the serpent deity from ancient Egyptian mythology, APEP will involve rockets launched from Wallops Flight Facility in Virginia. These rockets, equipped with secondary instruments, will measure changes in electric and magnetic fields, density, and temperature as they penetrate the ionosphere during the eclipse. Understanding these perturbations in the ionosphere is crucial for predicting disturbances that impact satellite communications and ensuring the smooth operation of our communication-dependent world.

The highly successful career of the Delta Heavy IV comes to a close as it launches a classified payload, NROL-70, on behalf of the U.S. National Reconnaissance Office (NRO). The NRO, responsible for the country's surveillance satellites, maintains secrecy about the specifics of its missions. This final launch aims to enhance the NRO's capabilities in providing intelligence to national decision-makers and supporting global humanitarian efforts. United Launch Alliance plans to retire both the Delta IV Heavy and the Atlas V to pave the way for its new Vulcan Centaur rocket, with the Atlas V scheduled for missions until 2029. The era of the Delta family concludes amidst a transition towards more advanced launch technologies and capabilities.

The Japan Aerospace Exploration Agency (JAXA) received a signal from the lander indicating it had restarted after hibernating to avoid freezing temperatures on the Moon's surface. Initially forced to shut down due to insufficient electricity generation from its solar cells, SLIM has persisted against the odds, reviving itself twice since its landing on January 19. Although not designed to endure the Moon's harsh conditions, the lander has continued to function, prompting uncertainty about JAXA's future plans for the resilient spacecraft after it successfully achieved its primary mission goal of a precise lunar landing within a 328-foot radius. (ANS thanks Passant Rabie, Gizmodo, for the above information) + China's Queqiao-2 satellite successfully launched from the Wenchang Space Launch Site on March 20th, reaching lunar orbit after a perilune braking maneuver near the Moon's surface on March 24th. Positioned to relay communications for future lunar missions, including Chang'e-4 and Chang'e-6, Queqiao-2's orbit will be adjusted to facilitate these missions and support China's ambitious lunar exploration program. Accompanying experimental satellites, Tiandu-1 and -2, also entered lunar orbit, conducting tests in communication and navigation. Queqiao-2's strategic orbit placement in the Moon's maria region holds significance for China's lunar exploration history, including past probe landings fifteen years ago on March 1, 2009. China's lunar missions, aiming to scout resources and establish a lunar base, signify a substantial endeavor parallel to NASA's Artemis Program, which plans to establish a sustained presence on the Moon with international collaboration.

The implementation is to take place through collaborative cooperation between internal, industrial and amateur radio participants. This activity will consolidate the requirements of the amateur and commercial satellite industry, weigh up different payload options, address the future user segment, develop scenarios for the financing, procurement and operation of such a payload, and investigate possibilities for placement on geostationary platforms. This past weekend, AMSAT-DL released their proposal. AMSAT-UK, along with the British Amateur Television Club, AMSAT-NA, and the UK Microwave Group previously made a separate proposal <https://www.amsat.org/wordpress/wp-content/uploads/2023/12/ESA-GEO-proposal…>. AMSAT-DL's proposal <https://amsat-dl.org/wp-content/uploads/2024/03/AMSAT-DL_Proposal-Geo-Paylo…> is written by the authors Kai Siebels, DH0SK and Matthias Bopp, DD1US. The proposal takes into account the technical requirements and needs of radio amateurs. Various aspects such as orbit, satellite and platform as well as payload are taken into account. Among the possible orbits such as MEO, HEO and GEO, the GEO orbit has proven to be the most suitable due to the extensive experience with OSCAR-100. A good compromise for the orbit position would be at ~43 degrees West to also support Eastern European countries and most of North America. A payload for amateur radio should allow the greatest possible scope for experiments on different bands. Six bands could be used for the uplink to enable experiments with different frequencies. The main uplink band is the 13 cm band, the main downlink band is the 3 cm band. All proposed band / NB transponder combinations can be implemented at the ground station with very reasonable effort. A dedicated AMSAT (Amateur Radio) mission based on an ESA-supported Micro GEO provides opportunities for several additional experiments that support AMSAT’s education, science and development goals to inspire young people with amateur radio technology. Finally, such a mission could also provide an excellent platform for disaster/emergency communications directly via the GEO satellite transponders. Micro GEO and QO-100 Micro GEO satellites are a new class of small geostationary communications satellites. They are around a tenth of the size of traditional geostationary satellites and typically measure just one cubic meter. This smaller size makes them significantly cheaper to manufacture and launch, allowing satellite operators to offer customized regional services or gap fillers that would not be financially feasible with large satellites. The amateur radio payload “QO-100” on the Es’hail-2 geostationary satellite, is a groundbreaking platform for the amateur radio community as it represents the first geostationary payload for amateur radio. The exemplary collaboration between AMSAT-DL, QARS and commercial partners on this project to integrate amateur radio payloads into a commercial satellite is a sign of the ongoing cooperation between the amateur radio community and the commercial space industry. This synergy can open up new avenues for amateur radio projects in space. QO-100 serves as a bridge between traditional approaches and new possibilities, while remaining firmly rooted in the principles of amateur radio. Its presence in geostationary orbit is a triumph for the amateur radio community and a sign that amateur radio can continue to play an important role in the exploration and use of space. SYNCART 2.0 on the Heinrich Hertz satellite The Heinrich Hertz Satellite Mission (also known as H2Sat) is a national, geostationary communications and research satellite. It was planned by the Space Agency of the German Aerospace Center (DLR) on behalf of the BMWi as part of the German government’s space strategy and serves both independent payloads (“hosted payloads”) and the in-orbit verification (IOV) of technologies as well as for research purposes. In July 2012, AMSAT-Germany (AMSAT-DL) proposed an amateur radio payload on the Heinrich Hertz satellite with the name “SYNCART 2.0” <https://amsat-dl.org/wp-content/uploads/2024/03/Projektvorschlag-HeinrichHe…>. This was a further development of the transponders of the P3-D AMSAT-OSCAR-40 satellite in the X and K amateur radio bands and a beacon in the 76 GHz band. The objectives of the amateur radio payload were as follows: - Development of the geostationary orbit for the amateur radio service - Communication resource for emergency and disaster radio (with low-power, small, simple technology) - In-orbit verification of SDX technologies - Promoting the spread of microwave technology - Gaining new insights by studying propagation conditions in the 76 GHz band for satellite applications - Provision of a signal for the calibration of antennas, converters and receivers, in particular for radio astronomical applications - Stimulating the acquisition of scientific and technical education, especially among schoolchildren and young people, by providing a permanently available satellite resource, e.g. for use in teaching, research and education - Acquisition of concrete knowledge and experience with satellite technologies and corresponding research opportunities in order to provide the space industry with highly qualified specialists. The concept aimed to make efficient and effective use of any remaining H2Sat capacity. The Heinrich Hertz feasibility study was completed in 2010. Planning phase B was carried out from 2011 to 2013. In July 2012, AMSAT-DL submitted its proposal for an amateur radio payload. Unfortunately, important positions on the antenna deck and with the payloads were already occupied at this point. There was also an approach for a Ka/Ka relaying transponder, but its use would have been limited to two small spot beams to northern Germany and southern Germany. At the time, this did not seem justifiable to our members and the amateur radio community in terms of the cost/benefit ratio. After it became clear that an amateur radio payload on the Heinrich Hertz satellite in the proposed form was not feasible, the proposal was finally withdrawn in September 2012. Miraculously, however, a new window opened just a few months later! Initial talks and contacts were held as early as December 2012, which ultimately led to an amateur radio payload on the Es’hail-2 satellite, also known as Qatar-OSCAR 100 or QO-100. Es’hail-2/QO-100 was launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. This project is a joint initiative of the Qatar Satellite Company, the Qatar Amateur Radio Society and AMSAT-DL. The satellite was built by Mitsubishi Electric Corporation in Japan and is located in a geostationary orbit at 26° East.

The ERMINAZ mission is a syndicated multi-PocketQube mission with a total of 7 PQs under the leadership of AMSAT-Germany, which also holds the launch contract with RFA under DLR support. The project is in collaboration between AMSAT-DL, AMSAT-EA (Spain), ESERO-Germany (Bochum Observatory) and Libre Space Foundation (Greece). The mission is to promote, advance and develop knowledge about space and amateur radio. ERMINAZ-1U & ERMINAZ-1V will transmit telemetry, images, provide a digipeat/store/forward functionally to all radio amateurs worldwide. ERMINAZ-1U will operate in the UHF amateur satellite band, while ERMINAZ-1V will operate in the VHF amateur satellite band. Only non-proprietary, open source and documented protocols, accessible to radio amateurs, will be used. This includes CCSDS telemetry, CW beacon, SSDV images, digipeater, AX.25 und possibly other modes. Telemetry and sensor data from radiation sensor and triaxial accelerometer / gyroscope / magnetometer will allow any radio amateur to participate by extending his knowledge about space. In addition, a digipeater and store & forward function will allow licensed radio amateurs to use ERMINAZ-1U/1V as a relay to communicate with other radio amateurs worldwide. The mission will conduct several experiments with different types of modulations, bandwidths, data rates and framing schemes: GFSK with data rate from 9600 up to 19200 GFSK with data rate from 9600 up to 19200 bits/s GMSK with data rate from 9600 up to 19200 bits/s BPSK with data rate from 9600 up to 19200 bits/s QPSK data rate from 19200 up to 38400 bits/s Frames will using three different framing schemes configurable upon the mission requirements: CSDS (residual or suppressed carrier) or IEEE 802.15.4 (preamble, sync) or AX.25. Planning a launch by RFA-Rocket Factory Augsburg AG from SaxaVord Spaceport into a 500km polar orbit not earlier than August 2024 together with UNNE-1 (HADES-E) and MARIA-G (HADES-F) from AMSAT-EA and QUBIK 5 from LibreSpace. Up and downlinks on 145.965 MHz (ERMINAZ-1V) and 435.775 MHz (ERMINAZ-1U) have been coordinated. *[ANS thanks AMSAT-DL and the IARU for the above information]* ------------------------------ LoRa Digipeater Satellite from the U. S. Naval Academy Scheduled for 2025 Launch A 3U CubeSat. USNA-16 will provide UHF LoRa digipeater service to the amateur radio service. Additionally, USNA-16 is a university-student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as the efficacy of student-designed passive magnetic pointing scheme for S-band operation. INCHsat payload will provide UHF service to the amateur radio service. In addition INCHsat payload is a university, student lead, educational amateur radio mission. It will test custom designed and built components. Specifically it will test a custom on-board computer, a custom radio (based off the OpenLST), a custom motherboard, and a custom antenna deployment system. USNA-16 is a student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as student-designed passive magnetic pointing scheme. TT&C will occur at UHF (437.235 MHz, will be designated as UHF-TTC in this document) and data downlinks will occur at 2.42GHz, both within the amateur bands and both using the LoRa protocol. This will be the first satellite launched by USNA using LoRa, with a potential future application of APRS over LoRa. USNA-16 will also provide UHF LoRa digipeater service at 437.235 MHz to facilitate communication between amateur operators. INCHSat is a student educational amateur radio mission built by students at the University of Maryland, including the licensee, KC3VBJ. There are no paid employees. The main goal is to enhance the aerospace skills of students in a professional context. The students are learning about satellites and space mission development and space communication by designing, building, and launching a payload onboard a cube satellite. The payload consists of a custom onboard computer, the radio, basic sensors, motherboard, and an antenna deployment system. Communication with the payload will be performed on the 437 MHz band from a ground station that will be constructed on the UMD campus. This payload radio (437MHz) will be designated as UHF-PLD in this document. USNA-16 will have a LoRa digipeater to serve the amateur satellite community. LoRa offers low-power beyond-line-of-sight digital UHF communications to the amateur community. Additionally, USNA-16 is a student educational amateur service mission that communicates on amateur frequencies. This will be the first satellite launched by USNA using the LoRa protocol, with a potential future application of APRS over LoRa. INCHsat payload is for the purpose of the training of UMD students in the construction and development of aerospace components. It also tests the components that we have developed on our own for future missions and research purposes with no commercial benefit. INCHsat payload will have a radio based on the open source OpenLST from Planet Labs to serve the amateur satellite community. INCHsat payload is also a student educational amateur service mission that will be communicating data obtained on amateur frequencies. Pending the mission success the code and schematics of the components used will be published as a cheaper alternative for amateur teams looking to launch a cube satellite. Proposing these downlinks UHF-TTC, 437.235 MHz, U/D, LoRa protocol @ 3.42 kbps data rate and on S-band, 2.42 GHz, LoRa protocol @ 60 kbps data rate.

On October 19, 1989, a monstrous X13 class solar flare triggered a geomagnetic storm so strong that auroras lit up the skies worldwide the following day. Had you been flying around the Moon at that time, you would have absorbed a dose that would most likely kill you within a month or so. This is why the Orion spacecraft that is supposed to take humans on a Moon fly-by mission this year has a heavily shielded storm shelter for the crew. But shelters like that aren’t sufficient for a flight to Mars. To obtain protection comparable to what we enjoy on Earth would require hundreds of tons of material, and that's simply not possible in orbit. The primary alternative—using active shields that deflect charged particles just like the Earth’s magnetic field does—was first proposed in the 1960s. Today, we’re finally close to making it work. Fascinating full article at https://bit.ly/3PANp67 (ANS thanks ARS Technica for the above information.) + Not an April Fool's joke: The U.S. Army has conducted a series of experiments, beginning in 1904 and continuing into the 1970s, on using trees as shortwave antennas. "It would seem that living vegetation may play a more important part in electrical phenomena than has been generally supposed. If, as indicated... in these experiments, the earth surface is already generously provided with efficient antennas which we have but to utilize for communications."

Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ------------------------------ AMSAT VP-Engineering Reviews GOLF Satellite Development Recently AMSAT News Service had the opportunity to interview Jerry Buxton, N0JY, AMSAT Vice President of Engineering, about the GOLF satellites that are currently in development. ANS: Jerry, the AMSAT engineering team is developing the GOLF (Greater Orbit, larger Footprint) satellites. What is the idea behind these satellites and the kind of functionality that will be added? JB: "Our original thought was for GOLF is to teach us how to go to Highly Elliptical Orbit (HEO.) Higher orbits have greater challenges than the satellites for LEO orbits we have built most recently. These are challenges like the higher radiation environment that the satellite must endure and controlling the satellite at higher altitudes. "We've had a significant additional requirement that has been added since GOLF was originally conceived. We must be able to deorbit the satellite on command. This is a pending FCC regulation. It is also likely that we will be required to move the satellite to avoid orbital debris in the future. To do this we have to be able to accurately know where the satellite is which requires a Global Navigation Satellite System (GNSS), which direction it is pointing which requires adding an Attitude Determination Control System (ADCS), and have a propulsion system to move it. This is not trivial. "Of course, we want to add more and more capabilities which require more power. "So, the purpose of the GOLF satellites is technology development, but they will have radios on board. Once they are up and we have proven the technology we will have another satellite that amateur radios operators can use." ANS: "What is the advantage of higher orbits?" JB: "Most of our current satellites are LEO, so we have about a 10 to 15-minute window to work the satellite. With higher orbits, the satellites will have a larger footprint (the signal will cover a larger area of the earth) and will be available or visible for longer periods of time. ANS: "Could you tell us a little more about how GOLF is being developed?" JB: "We will design and build the systems if we can, and we will acquire (buy) the functionality if need to. We are also using a stepped approach to capability development. We may fly the Attitude Determination Control System (ADCS) on the first satellite, add the propulsion system on the next satellite and so on. ANS: "Interesting! What else makes GOLF different from our previous satellites?" JB: "GOLF-TEE will have a new 3U space frame with deployable solar panels, which will flop open and lock into place. The solar cell system is an in-house design. It will have 14 cells on the satellite space frame and 28 on the deployable solar panels for a total of 42 cells, a significant increase in available power. "GOLF will have a radiation tolerant IHU (Internal Housekeeping Unit, or on-board computer.) It uses an automotive grade 32 bit ARM processor which has two processors. One is the primary. If one locks up the other takes over. The computer cores are in different areas of the chip and are at 90 degrees to each other, which lowers the likelihood of radiation affecting both processors. "We're adding microwave bands with a 10 GHz downlink experiment for increased data speed, that can also be used as a transponder downlink. This is a purchased radio. It has been a little bit of a challenge to fit the SDR into GOLF because it doesn't fit the normal layout. "GOLF will be much more complex than the FOX satellites. This complexity will increase the cost. This is because of the added capability the engineering team is developing like the additional solar panels as well as the selection and integration of purchased items like the ADCS or the 10 GHZ SDR radio." ANS: "Wow, the GOLF satellites will be a give us exciting new capabilities! When will they be launched?" JB: "The first is GOLF-TEE, which will be ready for launch in Q4 of 2025. GOLF-1 will be ready follow in Q4 of 2026. We should have some data and lessons learned from GOLF-TEE by then. "Here is a little more detail on the launch; GOLF-TEE and GOLF-1 have been approved by NASA as sound concepts and eligible for the ELaNa program. This program will pay for launch up to $300k of launch cost (covers everything up to a 3U satellite to LEO) and they will look for a launch that we can ride on. (We don't get to choose just when we launch.) A launch is not a guaranteed, but they always have found a ride for us." ANS: "Thank you, Jerry, for helping us understand these important new satellites!"

They transmit with high power and gain antennas so they are easily received with a simple dipole antenna and a $30 RTL-SDR dongle that plug into a computer that most everyone owns. They are always on and transmit data that is actually fun and usable: very clear pictures of ones' own locale that is easily decoded with free software. From this first experience, it is a simple jump to tracking and copying the ARISS voice and APRS repeaters, and from there getting a Technician class license and inexpensive handheld. In addition to the NOAA low earth orbit polar meteorology satellites, the Russian METEOR M2-4 was recently added on February 29, 2024. It was launched into a 800km sun-synchronous orbit with a 98 degree inclination from the Vostochny Cosmodrome aboard a Soyuz 2 rocket. Having achieved orbit, it is currently undergoing testing and calibration. There is currently no information when setup will be completed, but it did take several months for NOAA to get the NOAA-21 satellite running. Once it is functioning it will begin transmitting its low-rate picture transmission (LRPT) imagery on 137.1 MHz and/or 137.9 MHz. The antennas are right-hand circular polarization but are easy received with a home-made three-element yagi or even a simple dipole. Complete information on suitable SDR receivers, and free receiving and decoding software can be found at rtl-sdr.com. A simple You Tube search on the topic will also provide you with enough demonstration videos to help get you started. More information at https://www.rtl-sdr.com/.

This month Gabe has posted a 24-minute video on how to use parts from an old security pan-tilt camera mount to build an az-el satellite rotator. The rotator motors are controlled by software based on the Australian School Amateur Radio Club Network (SARKNET) Rotator Mark I Arduino code. The software can be run on either an Arduino device or on a PC laptop. Gpredict is used in this example to track the satellites. Gabe uses the rotator to steer a small dish but it looks strong enough to handle a lightweight yagi such as an Arrow or Elk if suitably counterweighted. Even if you aren't interested in building this az-el rotator, Gabe's video is a fascinating look at how an inventive mind and resourceful scrounger can make something actually useful.

Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary 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 satellite has been added to this week's AMSAT-NA TLE Distribution: SONATE-2 - NORAD Cat ID 59112 Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have been coordinated by the IARU. Thanks to Nico Janssen, PA0DLO, for the identification. The following satellite has been removed from this week's AMSAT-NA TLE distribution: BeliefSat-0 NORAD Cat ID 58695 End of mission. This mission was interesting as BeliefSat-0 is not a free flying satellite. Instead it is a "hosted payload" on a larger platform, in this case the spent upper stage of an Indian launch vehicle. The stage was modified such that it included solar panels and attitude control, so BeliefSat 0 and other payloads were designed to simply bolt on and plug in to a regulated power source. See https://www.isro.gov.in/POEM-3_Mission_achieves_Payload_objectives.html for details. While BeliefSat-0 and its host POEM-3 remain in orbit for now, it appears that BeliefSat-0 has been shut down as there have not been any successful observations of it in SatNogs for several weeks. POEM-3 will reenter within the next few weeks "leaving zero debris in space" according to the Indian Space Resource Organization.

Alan was one of the first Broadcasting majors at the University of Wyoming and began his career at KATI radio in Casper. He later worked for KCBS-FM and KGO TV in California. As microcomputers emerged in the industry, Alan evolved into a computer technologist, working at Northstar Computers, Fantasy Records, and Dolby Laboratories. During the winter months of 1983 and 1984, he spent time in London as computer consultant to Hollywood film filmmaker, Stanley Kubrick. In retirement, he turned into a travel photographer, touring worldwide and documenting his experiences in still photos and video. First licensed in 1966, he was a consistent voice on RS-44 and an avid experimenter on IO-117 and other digital modes from CM87 in northern California. He earned AMSAT GridMaster Award #62 of which he was very proud, while grateful to the many rovers who worked hard to make that happen for him. We will miss hearing Alan on the birds!

[ANS thanks Abdul Alshahrani, HZ1DG for the above information.] + Tom Van den Bon, ZR6TG has been toying with this idea of adding a "Widget" to his Icom IC-9700. Playing with satellites requires various kinds of software that requires a fully fledged PC connected to the radio for tracking the satellite, controlling the rotator and automatically adjusting for Doppler effect. While all of that software works perfectly fine, Tom always wondered if there wasn't a simpler solution which is always available and ready at the radio. Tom says, "I know there are a few satellite "controllers" available that allow you to do something similar, but I felt that those are either too specific (i.e., only one radio and one rotator) or was lacking some features. My idea around the Satellite Tracking widget is to try and combine everything I need in a single small display."

The Starship/Super Heavy vehicle lifted off from the company’s Starbase site at 9:25 a.m. Eastern. The liftoff was delayed by nearly an hour and a half because of ships in restricted waters offshore. SpaceX reported no technical issues during the countdown. [*Starship lifts off on its third integrated test flight March 14. Credit: SpaceX webcast*] The Super Heavy booster fired all 33 of its Raptor engines for nearly three minutes before executing “hot staging”, with the Starship upper stage’s engines igniting while still attached to Super Heavy before separating. The booster then performed burns to attempt what SpaceX webcast hosts called a “soft splashdown” in the Gulf of Mexico, where it would not be recovered. However, the landing burn did not appear to go correctly, and the company later said that the booster broke apart 462 meters above the ocean after lighting several Raptor engines for a landing burn. The Starship upper stage performed its burn, placing the vehicle onto its planned suborbital trajectory. It avoided the fate of the previous Starship launch in November, when the vehicle broke apart late in its burn after catching fire while venting propellant. While in space on its suborbital trajectory, SpaceX opened a payload bay door that will be used on later Starship vehicles for deploying Starlink satellites. It also performed an in-space propellant transfer demonstration as part of a NASA contract where it would move propellant from one tank within the vehicle to another. SpaceX said it was evaluating the data from both tests. SpaceX had planned to perform a brief relight of a Raptor engine on Starship about 40 minutes after liftoff, but the company said on the webcast that this test was skipped for reasons not immediately known. The company later said the engine test was called off because of the vehicle’s roll rates. Several minutes later, the vehicle started reentry. A camera mounted on a flap on Starship provided dramatic images of the reentry, relayed through Starlink satellites. Telemetry was lost about 49 and a half minutes after liftoff when the vehicle was descending through an altitude of 65 kilometers. SpaceX later said on the webcast that it lost contact through both its own Starlink satellites as well as through NASA TDRSS data relay satellites at the same time, speculating that the vehicle may have broken up. While the mission did not achieve all its test objectives, the company considered the launch a success. “What we achieved on this flight will provide invaluable data to continue rapidly developing Starship,” it said in a statement.

Moghbeli, Mogensen, Furukawa, and Borisov are returning after nearly six-months in space as part of Expedition 70 aboard the International Space Station. The Crew-7 mission lifted off <https://www.nasa.gov/news-release/nasas-spacex-crew-7-launches-to-internati…> at 3:27 a.m. on Aug. 26, 2023, on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. About 30 hours later, Dragon docked <https://blogs.nasa.gov/spacestation/2023/08/27/spacex-crew-7-mission-docks-…> to the Harmony module’s space-facing port. Crew-7 undocked at 11:20 a.m. Monday, March 11, to begin the trip home. Moghbeli, Mogensen, Furukawa, and Borisov traveled 84,434,094 miles during their mission, spent 197 days aboard the space station, and completed 3,184 orbits around Earth. The Crew-7 mission was the first spaceflight for Moghbeli and Borisov. Mogensen has logged 209 days in space over his two flights, and Furukawa has logged 366 days in space over his two flights. [ *A thermal screenshot showing the successfully deployed four parachutes of the Dragon Capsule as it makes its descent on March 12](Image credit: NASA)* Throughout their mission, the Crew-7 members contributed to a host of science and maintenance activities and technology demonstrations <https://www.nasa.gov/mission_pages/station/research/news/crew-5-scientific-…>, including a number of ARISS amateur radio contacts. Moghbeli conducted one spacewalk, joined by NASA astronaut Loral O’Hara, replacing one of the 12 trundle bearing assemblies on the port solar alpha rotary joint, which allows the arrays to track the Sun and generate electricity to power the station. The crew contributed to hundreds of experiments and technology demonstrations <https://www.nasa.gov/missions/station/iss-research/nasas-spacex-crew-7-comp…>, including the first study of human response to different spaceflight durations, and an experiment growing food on the space station. This was the third flight of the Dragon spacecraft, named Endurance. It also previously supported the Crew-3 and Crew-5 missions. The spacecraft will return to Florida for inspection and processing at SpaceX’s refurbishing facility at Cape Canaveral Space Force Station, where teams will inspect the Dragon, analyze data on its performance, and process it for its next flight. The Crew-7 flight is part of NASA’s Commercial Crew Program <https://www.nasa.gov/exploration/commercial/crew/index.html> and its return to Earth follows on the heels of NASA’s SpaceX Crew-8 launch, which docked to the station March 5, beginning another science expedition. That crew consists of Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Alexander Grebenkin, RZ3DSE.

Originally intended to demonstrate satellite refueling, the mission expanded to include in-orbit assembly, incorporating a 16-foot robotic arm named SPIDER. Despite significant congressional funding, the project faced continual delays and ballooning costs, reaching $1.5 billion with an estimated additional cost of nearly $1 billion for launch. Changes in the satellite servicing market, with a shift towards alternative technologies like Northrop Grumman's Mission Extension Vehicle, contributed to the cancellation. Maxar, the prime contractor for OSAM-1, faced criticism for poor performance, leading to delays and cost overruns, although the company cited other factors like the COVID-19 pandemic. The cancellation impacts approximately 450 workers at NASA's Goddard Space Flight Center, prompting NASA to review strategies to mitigate workforce impacts and consider alternative uses for developed technologies. (ANS thanks Ars Technica, for the above information.) + China's human spaceflight agency, CMSA, is progressing towards its goal of landing astronauts on the moon before 2030. The spacecraft developed for this purpose has been named Mengzhou, translating to "Dream Vessel," for lunar missions, and Lanyue, meaning "Embracing the Moon," for orbital travel. These names were selected through a public contest, with Mengzhou having a variant for low Earth orbit (LEO) carrying seven astronauts and a moon version transporting three astronauts into lunar orbit. The China Aerospace Science and Technology Corporation (CASC) is designing and building the spacecraft and lander, along with a new rocket, the Long March 10. The moon landing plan involves two Long March 10 rockets launching Mengzhou and Lanyue, rendezvousing in lunar orbit, with astronauts descending to the lunar surface. A 440-pound crew rover will accompany the lunar lander. Progress on various mission hardware is reportedly on track, including completed development of the primary spacecraft and technical proposals for launch and landing sites. Recently, models of the rocket, spacecraft, and lander were showcased at an exhibition in Shanghai.

The coverage will commence with a change-of-command ceremony at 11:55 a.m. EDT. Astronauts Jasmin Moghbeli, Andreas Mogensen, Satoshi Furukawa, and Konstantin Borisov will conclude their nearly six-month science mission. Weather permitting, the SpaceX Dragon spacecraft is set to undock on March 11 at 11:05 a.m., with splashdown targeted for as early as 5:35 a.m. on March 12 off the Florida coast. The live coverage will be available on NASA+, NASA Television, the NASA app, and the agency's website, featuring farewell remarks, hatch closure, undocking, and splashdown events, as well as a media teleconference on March 12 with key participants. (ANS thanks NASA for the above information) + SpaceX is aiming for the third test flight of its Starship rocket on March 14, as announced through a post on the X platform. The Starship vehicle comprises a stainless-steel reusable upper stage, also known as Starship, and a Super Heavy first-stage booster, standing over 400 feet tall together. A recent critical fueling test at the Starbase facility in Texas involved pumping over 10 million pounds of liquid methane and liquid oxygen into the rocket. The upcoming launch follows two previous test flights in April 2023 and November 2023, where Starship faced issues like failure to separate from the first-stage booster and a subsequent explosion of the Super Heavy. After the second test, the FAA identified seventeen corrective actions, all of which SpaceX claims to have completed, addressing issues related to leak reduction, fire protection, and propellant vent operations. The Starship and Super Heavy, designed for full reusability, are pivotal for NASA's Artemis 3 mission to land astronauts on the moon by 2026. (ANS thanks Brett Tingley, Space.com, for the above information) + NASA has identified a growing air leak on the International Space Station (ISS) located at the end of the Russian service module. The leak, situated in Russia's Zvezda service module, initially released one pound of air per day but accelerated to over two pounds daily in early February. Despite the increased rate, NASA assures that it does not currently jeopardize the safety of the ISS crew or impact the station's operations. Collaboration between the United States, Russia, Europe, Japan, and Canada is underway to address the situation. Roscosmos, the Russian space agency, confirms ongoing monitoring and asserts that there is no immediate threat to the crew or the station itself. The leak is in a three-foot-long area and has prompted precautionary measures, including sealing off the affected vestibule to mitigate further air loss from the rest of the space station. (ANS thanks Will Sullivan, Smithsonian Magazine, for the above information) + The inaugural components for Europe's new Ariane 6 rocket have reached the port of Pariacabo in Kourou, French Guiana, transported by the container ship, Canopée. Manufactured across Europe, the central core arrived on Canopée, which uses sails to reduce emissions and save up to 30% on fuel during its 10-day, 7,000 km journey. The rocket's stages were produced in various European locations, with the main engine and stage integrated in Les Mureaux, France, and the upper stage and insulation in Bremen, Germany. Following transport, the components were offloaded and taken to the Ariane 6 assembly building, a few kilometers away, where they will undergo integration before liftoff. The boosters, already at Europe's Spaceport, are P120C solid propulsion boosters similar to those used for the Vega-C rocket. The central core will be assembled horizontally and then transported to the launchpad, where it will be erected, followed by the addition of boosters and the upper stage, with the goal of a summer launch for Flight Model-1.

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 satellite has been removed from this week's AMSAT-NA TLE distribution: IT-SPINS NORAD Cat ID 49017 Decayed from orbit on or about 25 February 2024 *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, for the above information]* ------------------------------ *Need new satellite antennas? Purchase an M2 LEO-Pack from the **AMSAT Store! <https://amsat.org/product-category/hardware/>**When you purchase through **AMSAT, a portion of the proceeds goes towards **Keeping Amateur Radio in Space.* ------------------------------ ARISS News Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide. *“IES Pedro Simón” Abril High School, Alcaraz, Spain, telebridge via K6DUE* The ISS callsign is presently scheduled to be NA1SS The scheduled crewmember is Loral O’Hara KI5TOM The ARISS mentor is IKØUSO Contact is go for: Mon 2024-03-04 11:21:02 UTC 70 deg Watch for Livestream at https://www.youtube.com/watch?v=9Xgk4YZT5w4 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 crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), 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. 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 *[ANS thanks Charlie Sufana, AJ9N, one of the ARISS operation team mentors for the above information]* ------------------------------ Upcoming Satellite OperationsQuick Hits: From…me! (K5ZM) I’ll be heading back to SGU for some sorely needed R & R and will be there from *Saturday, 2 Mar* through *Saturday, 9 Mar* and leaving on the morning of the 10th. Rove-wise, the main objectives are reactivations of the *DM46/DM47 & DM56/DM57 gridlines*, plus a trip just a bit farther south for the *DM44/DM45 gridline* -that will be new /r for me. Given the windshield time involved, I’m thinking these will take the form of a Mon/Wed/Fri scenario, but that’s not set in stone. I don’t necessarily care about the order in which I do them. Let me know your thoughts. I’ll probably hit DM36 (and of course DM37) and maybe another grid or two in between. Major Roves: *NOIRMOUTIER ISLAND SAT DXPEDITION 2024* *F4DXV* Jérôme (@F4DXV <https://twitter.com/f4dxv>) and *EA4NF* Philippe ( @EA4NF_SAT <https://twitter.com/ea4nf_sat>) announce that they will be actívating Noirmoutier island EU-064 IN86 from April 1 to 4, 2024 with the special callsign *TM4J* In an exciting initiative, Jérôme F4DXV and Philippe EA4NF are preparing for an exceptional expedition to the island of Noirmoutier from 1 to 4 April 2024.

His obituary can be found at https://www.johnsonfuneralhome.net/obits/deacon-george-k-carr-ii/. George was a frequent and friendly presence on amateur satellites for many years. AMSAT extends our condolences to George's family and friends. + Bob Heil, K9EID, became a silent key this past week after a battle with cancer. From the Heil Facebook page: * "Our beloved founder, Dr. Bob Heil, K9EID, is now a Silent Key. Bob fought a valiant, year-long battle with cancer, and passed peacefully surrounded by his family. Bob’s lifelong passion for amateur radio was clear to everyone involved in the hobby. Everything Bob did for the betterment and growth of amateur radio - from his instructional handbooks and countless presentations to his support of the ARRL and youth programs - was based on the foundation and spirit of service. Bob was an Elmer to all of us. While Bob’s presence will dearly be missed, his impact on the hobby and everyone in it will forever be felt. On behalf of Bob to all ham radio operators worldwide, 73."* Dr. Heil was a longtime friend of AMSAT and we extend our condolences to his family and friends. (ANS thanks Heil for the above information.) + After spending over a decade on a mission in space, a defunct 5,000 pound satellite returned to Earth on Feb. 21, splashing down in the Pacific Ocean somewhere between Alaska and Hawaii. After tracking the dead satellite for most of the day, the European Space Agency confirmed the satellite had returned to earth by about 19:30 UTC. ERS-2 launched in 1995 and was initially planned to serve the ESA for three years. However, it remained in operation until 2011, providing data for over 5,000 projects, including tracking Earth's shrinking polar ice, sea levels and atmospheric make-up. The majority of the 2.5 ton satellite disintegrated in Earth's atmosphere, though remaining debris likely landed in the north Pacific. (ANS thanks USA Today for the above information.) + The International Space Station (ISS) took more than a quarter-century, 42 space launches, and $150 billion to build. Voyager Space is cooperating with multiple companies and space agencies, including Europe's Airbus, American defense contractor Northrop Grumman, and -- intriguingly -- Hilton Hotels, to build a "Starlab" commercial space station to replace the aging ISS. On Jan. 31, the Starlab space station team announced that it had hired SpaceX to launch its entire Starlab space station to Low Earth Orbit "in a single mission prior to the decommissioning of the International Space Station." SpaceX will use its new Starship megarocket for this mission. Furthermore, "Starlab will ... be fully outfitted on the ground, and ready to permanently host four crew members in LEO to conduct microgravity research and advanced scientific discovery," say the companies. (ANS thanks Yahoo! Finance and the Motley Fool for the above information.) + India has unveiled four Air Force pilots who have been shortlisted to travel on the country's maiden space flight scheduled for next year. The Gaganyaan mission aims to send three astronauts to an orbit of 400km and bring them back after three days. India's space agency, ISRO, has been carrying out a number of tests to prepare for the flight. The officers were introduced as Group Captain Prashanth Balakrishnan Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap and Wing Commander Shubhanshu Shukla. If it succeeds, India will become only the fourth country to send a human into space after the Soviet Union, the U.S. and China. (ANS thanks the BBC for the above information.) + SLIM, the wrong-side-up Japanese lander, which had been hibernating through the two-week-long, -130 °C lunar night and the following week of unfavorable illumination angles (due to its aforementioned tipsy state), has somewhat surprisingly responded to commands from JAXA. The mission was not originally designed to survive the frigid night time temperatures. However, in a bit of situational irony, the agency had to shut the lander down again almost immediately due to overheating of the communications equipment in the 100 °C+ lunar mid-day.
