The system is expected to remain active for testing through March 2, 2026, giving stations worldwide an opportunity to receive packet transmissions and attempt limited digipeating through the orbiting station. Operators wishing to access the ISS digipeater are advised to include ARISS or APRSAT in the PATH field of their transmissions. The Service Module station is operating under the call sign RSØISS using FM packet at 1200 bps. ARISS recommends transmit power of 5 watts or less, preferably with a directional antenna, to improve uplink reliability and help minimize interference. The current activation follows a prolonged outage of the Service Module amateur radio system that began during ARISS SSTV Series 30 in November 2025. Images were received early in the event, but subsequent passes produced no SSTV transmissions, and the event was ultimately scrubbed. The Service Module radio used for APRS and SSTV was then taken out of service while teams investigated the problem. [https://www.amsat.org/wordpress/wp-content/uploads/2026/03/ARISS_APRS_Testing_ISS_Service_Module-1024x1024.jpg] The packet radio in the ISS Zvezda Service Module is enabled for APRS testing through March 2, 2026. [Credit: ARISS] Subsequent ARISS updates reported that the primary Kenwood D710GA radio was replaced with an onboard spare D710E while teams continued troubleshooting and preparing reset procedures. Status reports in the following months continued to show the Service Module radio offline while restoration efforts were planned and carried out. The newly announced APRS configuration suggests the system is now being evaluated through on-orbit testing following these repair activities. Temporary activations such as this allow radio amateurs worldwide to help confirm reception, observe system behavior, and provide useful reports while the station's amateur radio capability is assessed. ARISS encourages operators to monitor official status channels for schedule updates and to share reception reports as testing continues. Additional information on ISS amateur radio operations and current station status is available at https://www.ariss.org.

The satellite, using the callsign BNØUTC, is operated with support from National Formosa University. NUTSAT-3 is designed to provide voice repeater, APRS, and telemetry services to the global amateur satellite community. The primary payload is a cross-band FM voice repeater with an uplink on 145.980 MHz using a 67 Hz CTCSS tone and a downlink on 435.250 MHz. Telemetry will be transmitted on 437.850 MHz using 1k2 AFSK with AX.25 protocol. All telemetry is unencrypted and intended for public reception and analysis. An APRS digipeater will also operate on 145.825 MHz, allowing stations to relay position and status data through the satellite. The digipeater is expected to respond to both its unique callsign and the ARISS alias using standard APRS paths. The open telemetry format and public data distribution are intended to encourage worldwide participation, including monitoring through networks such as SatNOGS.

[Credit: Space One] Beyond communications service, the mission includes a strong educational component. Students will participate in RF design evaluation, mission analysis, and satellite communications performance studies. Public dashboards and shared telemetry are planned to promote transparency and community collaboration. NUTSAT-3 is manifested for launch aboard a Space One KAIROS rocket from Spaceport Kii in Kushimoto, Japan into a planned 500 km polar orbit. Space One recently postponed the vehicle's third flight following weather analysis, and the launch window now extends through March 25, 2026. A specific launch date is expected to be announced approximately two days prior to liftoff. KAIROS conducted two previous launch attempts in March and December 2024, both of which ended in mission failure during early flight. The upcoming mission will mark a return-to-flight opportunity for the Japanese commercial launch provider. Frequency coordination for NUTSAT-3 was requested on December 25, 2025, and completed on January 31, 2026.

With about one month remaining before submissions close for the Astro Pi Mission Zero coding challenge on March 23, 2026, her mission highlights ongoing opportunities for young people to run their own code aboard the space station. Astro Pi Mission Zero, organized by ESA in partnership with the Raspberry Pi Foundation and the European Space Education Resource Office (ESERO), gives young people the chance to have their code run in space. Participants write a short Python program that reads data from the Astro Pi color and luminosity sensor aboard the ISS and uses it to set the background color of a personalized image displayed for astronauts as they go about their daily tasks inside the Columbus laboratory module. Adenot serves as an ambassador for the Astro Pi initiative, reinforcing the connection between astronaut missions, STEM education, and global outreach. Licensed in amateur radio, she is among the ISS crew members able to support educational engagement activities, including ARISS (Amateur Radio on the International Space Station), which enables scheduled radio contacts between astronauts and students around the world. [https://www.amsat.org/wordpress/wp-content/uploads/2026/03/Astro_Pi_IR_Computer_On_ISS-1024x576.png] An Astro Pi IR computer aboard the ISS supports ESA's student programs that run code in space. [Credit: Raspberry Pi Foundation / ESA] Mission Zero is designed to be accessible to beginners and can typically be completed in a single one-hour session using only a web browser. Young people aged 19 and under may participate individually or in teams of up to four, working under the supervision of a registered mentor such as a teacher, educator, parent, or youth leader, who provides the classroom submission code required to enter programs. All eligible entries that follow the official guidelines are scheduled to run on the ISS for up to 30 seconds. Each successful team receives a certificate signed by an ESA astronaut showing the exact time their program executed and the station's orbital position at that moment, providing a lasting record of their software running in space. Programs such as Astro Pi Mission Zero complement ARISS school contacts by offering multiple ways for students to interact with the International Space Station - whether by speaking directly with astronauts over amateur radio or by running their own code aboard station hardware. Amateur radio clubs and educators are encouraged to share this opportunity while time remains for participation. Eligibility requirements vary by location; readers should consult the official Mission Zero website for full details: https://astro-pi.org/mission-zero [ANS thanks the ESA, the Raspberry Pi Foundation, and the European Space Education Resource Office for the above information] ________________________________ Elon Musk Suggests Moon-Based Mass Driver for Future Satellite Deployment SpaceX founder Elon Musk has suggested building a giant electromagnetic "catapult" on the Moon to launch satellites into space, reviving a concept first explored more than fifty years ago. In early February, Musk told employees at xAI that the company could eventually establish lunar factories to build artificial-intelligence satellites and launch them using an electromagnetic mass driver rather than conventional rockets. Musk argued that advances in heavy-lift launch capability, particularly SpaceX's Starship vehicle, could enable delivery of large amounts of cargo to the lunar surface. Once infrastructure exists, he suggested that manufacturing satellites on the Moon and launching them from there could dramatically reduce costs. He also noted that in-space propellant transfer and lunar industrial development could support a permanent scientific and manufacturing presence beyond Earth. The concept of a lunar electromagnetic launcher is not new. Physicist Gerard O'Neill proposed similar "mass drivers" in the 1970s as a way to fling mined lunar material into space for use in constructing orbital habitats and solar-power satellites. Working with colleagues and student researchers at MIT, O'Neill helped build experimental prototypes demonstrating that electromagnetic acceleration could launch payloads without chemical rockets. Later designs suggested that a system only a few hundred feet long might be sufficient to send material off the Moon. [https://www.amsat.org/wordpress/wp-content/uploads/2026/03/Moon_Based_Mass_Driver_NASA_Concept.jpg] A 1970s NASA concept shows a lunar electromagnetic mass driver designed to launch payloads from the Moon into space. [Credit: NASA] More recent studies have continued to explore the practicality of lunar launch systems. In a 2023 report to the U.S. Air Force Office of Scientific Research, General Atomics researcher Robert Peterkin argued that modern electromagnetic launchers could be powered by abundant solar energy on the Moon, eliminating the need to transport large quantities of rocket fuel from Earth. He suggested that adapting technologies such as the Navy's electromagnetic aircraft launch system could form the basis of a reliable lunar launch capability. Such systems could play a role in a broader lunar industrial ecosystem. Early lunar bases would initially depend on machinery and supplies delivered from Earth, but the long-term goal would be to use lunar resources - including silicon, aluminum, titanium, iron, and water ice - to manufacture hardware locally. Launching satellites or raw materials from the Moon's weaker gravity could make resupply of lunar orbit or deep-space infrastructure far more economical than launching everything from Earth. While Musk's timeline and plans remain speculative, the renewed discussion highlights growing interest in lunar manufacturing and infrastructure to support future space activity. For the satellite and amateur-radio community, concepts like lunar mass drivers point toward a future in which large-scale space construction, power generation, and satellite deployment may increasingly take place beyond Earth's surface.

(ANS thanks AMSAT-HB for the above information) + NASA's Artemis II lunar mission faces a potential delay after engineers identified a helium flow issue in the upper stage of the Space Launch System rocket during recent testing at Kennedy Space Center. The helium system is used to pressurize fuel tanks and purge propellant lines, and the anomaly requires the rocket to be rolled back to the Vehicle Assembly Building for inspection and repair. The move removes the possibility of a March launch attempt, with NASA now targeting no earlier than April while teams investigate the cause and determine whether additional testing will be required. Artemis II is planned to send astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen on a roughly 10-day mission looping around the Moon. The flight will mark the first human journey beyond low Earth orbit since the Apollo era and is a key step toward future lunar landing missions. NASA officials say launch timing will depend on repair progress, data review, and confirmation that the rocket's systems perform as expected after returning to the pad. (ANS thanks CNN for the above information) + Europe's Ariane 6 rocket flew its most powerful configuration, the Ariane 64, for the first time on February 12, successfully launching 32 Amazon broadband satellites into low Earth orbit from the Guiana Space Center in French Guiana. The satellites were deployed into an approximately 465-kilometer orbit less than two hours after liftoff, and Arianespace confirmed mission success. The spacecraft are part of Amazon's planned Amazon LEO broadband constellation, intended to compete with SpaceX's Starlink network. Amazon has booked launches across multiple providers, including Ariane 6, Vulcan, New Glenn, Atlas V, and Falcon 9, as it works toward deploying thousands of satellites. Delays among several launch providers have tightened global launch availability, prompting Amazon to secure additional rides where possible. The successful debut of the Ariane 64 restores Europe's heavy-lift launch capability and highlights the continuing rapid expansion of large low-Earth-orbit satellite constellations. (ANS thanks Ars Technica for the above information) + A total lunar eclipse on March 3, 2026, will produce a dramatic "blood moon" visible across North and South America along with parts of Asia, Australia, and the Pacific region. The event occurs when Earth passes between the Sun and the full Moon, casting Earth's shadow across the lunar surface and turning it reddish during totality. The total phase will last about 58 minutes, though how much of the eclipse is visible will depend on local horizon and weather conditions. In the United States, the eclipse takes place during the early-morning hours before dawn, with some eastern locations seeing only part of the event as the Moon sets. Lunar eclipses are safe to observe with the unaided eye, binoculars, or telescopes, making them useful opportunities for public outreach and astronomy education.

After delivering about 12,000 pounds of supplies, scientific investigations, hardware, and other cargo to the ISS for NASA and its international partners, JAXA’s (Japan Aerospace Exploration Agency’s) uncrewed HTV-X1 cargo spacecraft departed the ISS on Friday, March 6. The spacecraft arrived at the space station on Oct. 29, 2025, after launching Oct. 25 on an H3 rocket from Japan’s Tanegashima Space Center. The HTV-X1 spacecraft will boost itself to a 500km circular orbit where it will remain for more than three months acting as a scientific platform for JAXA’s experiments. After attaining this higher orbit, HTV-X1 will deploy Ten-Koh 2, a 6U cubesat constructed by Nihon University carrying a variety of amateur radio experiments. These will include: - A linear transponder, developed by JAMSAT, that will operate two days each week (schedule to be announced). Transponder frequencies that have been coordinated with the International Amateur Radio Union (IARU) feature an uplink in the range 145.895-145.935 MHz with downlink 435.875-435.915 MHz. - Digitalker with pre-loaded audio to be transmitted at 435.895 MHz. - Transmission of pre-loaded digital images created in cooperation with students from the Faculty of Arts, also at 435.895 MHz. - Demonstration of microwave band communication technology at 5.8 GHz in the microwave band. - Tests of high-speed data transmission at 38.4 kbps in 4FSK. Following the deorbit command, HTV-X1 will dispose of several thousand pounds of trash from the ISS during re-entry into Earth’s atmosphere, where it will burn up harmlessly. However, Ten-Koh 2 is expected to remain in orbit and active for approximately one year to 18 months. *[ANS thanks NASA and IARU for the above information.]* ------------------------------ GridMasterMap Satellite Top 100 Rovers March 2026 Rankings The March 2026 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in satellite operations, as determined by @GridMasterMap on X (formerly Twitter), have been released.

The training, from February 26 to March 3, is transforming the campus into a hub of innovation. Building on their past success of a 12,076-kilometre transmission to Antarctica via the QO-100 satellite, this year’s training elevates the challenge by focusing on Low Earth Orbit (LEO) satellites. Students are actively engaged in hands-on learning, constructing and utilizing homemade antenna systems to track these fast-moving satellites across the sky, according to organizers. International specialists from Japan, France and Australia are providing mentorship, guiding students through the complexities of installing ground stations and communicating with a variety of satellites, including the geostationary QO-100 and LEO satellites like RS-44 and SO-50. *Space and satellite training during the first session at NPIC, held last year. Credit: NPIC and *The Phnom Penh Post*.* “I wanted to show Cambodian students that space technology is accessible. Watching them successfully track an LEO satellite today proves that our youth are ready for the future,” said Jorge Paulo, a French Marine Electronics and Telecommunications System expert. Mori Mikio, an amateur radio satellite technician from Japan, emphasized the event’s impact, highlighting how the real success is not just in the technical milestones, but in witnessing the passion of the participants. “Seeing students successfully track LEO satellites with homemade antennas is a powerful reminder of why this event exists,” he said. Reth Sengvisoth, one of the organising committee members, shared his satisfaction with their efforts. He said the months of planning and coordination went into bringing this international training to life. *[ANS thanks *The Phnom Penh Post* for the above information.

Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/. *URGENT MESSAGE:* From TS Kelso of CelesTrak “[The US Space Force 18th Space Defense Squadron] will run out of 5-digit catalog numbers at 69999 not 99999, which is estimated to occur around 2026?07?20 (we’re currently at 68014). At that point, newly cataloged objects will have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format. CelesTrak developed new formats that removed this limitation (and finally fixed the Y2K problem) in May 2020 and immediately began providing GP data in those formats for software developers. The same limitations apply to the legacy fixed-field SATCAT. Follow @TSKelso on Bluesky for the latest updates, tutorials, and changes as we approach this transition. Spread the word!” AMSAT is presently alpha testing dissemination of orbital data aka “General Perturbations Data” or “GP Data” in formats that do not have the 5 digit object number limitation and will solicit public help for beta testing in April 2026. Many software packages used by hams already accept at least one of the new formats, and we would like to work through any issues before new satellites arrive without TLE sets. AMSAT will continue to disseminate TLE data for all satellites cataloged below 69999 indefinitely. NOAA Cat ID 67291 has been *renamed* “RS95S (QMR-KWT-2)” The following satellites have been *removed* from this week’s AMSAT TLE Distribution: RSP-03 NORAD Cat ID 65732 Decayed from orbit on or about 16 February 2026 BOTAN NORAD Cat ID 65942 Decayed from orbit on or about 03 March 2026 MO-122 NORAD Cat ID 60209 End of mission, last telemetry 25 August 2025 CEVROSAT1 NORAD Cat ID 66309 End of mission, last telemetry 09 November 2025 CO-57 NORAD Cat ID 27848 End of mission, date unknown CO-58 NORAD Cat ID 28895 End of mission, date unknown EO-80 NORAD Cat ID 40032 End of mission, date unknown FloripaSat 1 NORAD Cat ID 44885 End of mission, date unknown *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager for the above information.]* ------------------------------ [image: SDR Gen 2 Ad - 2026] ------------------------------ NASA Reveals Astronaut Who Required Evacuation From ISS NASA astronaut Mike Fincke, KE5AIT, Crew-11 pilot and commander of the International Space Station’s (ISS) Expedition 74, has revealed that it was his medical issue that prompted the evacuation of the four Crew-11 astronauts from the space station in January. *NASA astronaut Mike Fincke, KE5AIT (Credit: NASA)* The exact nature of his ailment remains undisclosed, but Fincke’s statement clarified that the issue, while not considered an emergency, required “advanced medical imaging not available on the space station.” As a result, Fincke and his crewmates ? NASA astronaut Zena Cardman, KJ5CMN, Japanese space agency astronaut Kimiya Yui, KG5BPH, and Roscosmos cosmonaut Oleg Platonov ? returned to Earth aboard the Crew Dragon “Endeavour” on Jan. 15, about a month earlier than originally planned. The issue arose on Jan. 7, while Fincke and Cardman were preparing for an upcoming spacewalk. “The agency is monitoring a medical concern with a crew member that arose Wednesday afternoon aboard the orbital complex,” NASA officials said in an emailed statement on Jan. 7, declining to elaborate on the nature of that concern or the astronaut it affected. Then, on Jan. 8, the agency announced that Crew-11 would end early so the issue could be addressed here on Earth. Crew-11 splashed down aboard Endeavour in the Pacific Ocean, off the coast of San Diego, on Jan. 15, leaving a skeleton crew of three aboard the ISS. SpaceX’s Crew-12 mission was originally slated to launch in mid-February, with a typical handover period between them and Crew-11 expected after their arrival in low Earth orbit, allowing the newcomers time to acclimate to microgravity and life aboard the station. Efforts by SpaceX and NASA allowed for an earlier target date of their Falcon 9 launch aboard Crew Dragon “Freedom,” which lifted off Feb. 13 and returned the ISS to its regular crew complement of seven. *[ANS thanks Space.com for the above information.

The agency said a Progress cargo capsule is now scheduled to blast off to the ISS on March 22. The facility suffered a still unexplained mishap last November during the launch of a Soyuz capsule carrying two Russians and one American to the orbiting station. The pad is the only location where Russia can launch its manned Soyuz capsules, which are a mainstay transport and cargo vehicle for the station. *(ANS thanks Radio Free Europe for the above information.)* + SpaceX launched the 600th Starlink satellite of 2026 during predawn Falcon 9 rocket flight from Cape Canaveral on March 4. The Starlink 10-40 mission added another 29 broadband internet satellites into low Earth orbit. *(ANS thanks SpaceflightNow for the above information.

CFT launched on June 5, 2024, sending NASA astronauts Suni Williams, KD5PLB, and Butch Wilmore to the International Space Station (ISS) for a planned 10-day stay. Starliner reached the orbiting lab safely. On the way, however, the spacecraft suffered multiple thruster failures and temporarily lost “six degree of freedom” control ? the ability to precisely maintain its desired orientation and trajectory. NASA prolonged the orbital stay of Williams and Wilmore multiple times to study Starliner’s thruster issues. In the end, the agency decided to bring the capsule home uncrewed, which occurred on Sept. 6. Williams and Wilmore, meanwhile, stayed aboard the ISS. They came home on a SpaceX Crew Dragon capsule in March 2025, having spent about nine months in space instead of the originally planned 10 days. Both have since retired from the agency. *(ANS thanks Space.com for the above information.
