FO-29 Update

Fuji-OSCAR 29 (FO-29 / JAS-2), the long-lived Japanese amateur radio satellite launched in 1996, continues to operate its V/U inverting analog linear transponder under the control of the Japan Amateur Radio League (JARL). Because the onboard batteries have failed years ago, the satellite depends entirely on solar power and can only function when its solar panels are illuminated.

Current Status (May 2026)

FO-29 entered a full-sunlight orbit in early March 2026 and lasted approximately 40 days. This continuous operation ended around April 21, 2026, after which the satellite entered an eclipse period for about one month.

A second, longer full-sunlight period is expected from approximately May 20 to mid-November 2026, during which continuous operation should resume.

Transponder Details

Mode: V/U inverting linear transponder (SSB and CW only)
Uplink: 145.900 – 146.000 MHz (LSB)
Downlink: 435.800 – 435.900 MHz (USB)
CW Beacon: 435.795 MHz (typically 100 mW)
Digitalker: 435.910 MHz FM (rarely activated)
The digital BBS (1k2/9k6) remains non-operational.

Important Restriction:
Digital modes are generally NOT permitted on the FO-29 linear transponder due to licensing and operational constraints.

Operating Procedure

During eclipse periods (or the transition out of full sunlight), the JARL control team sends specific commands to activate the transponder at designated UTC times. If the transponder does not turn on within about 2 minutes of the command start, the team terminates the attempt.

During confirmed full-sunlight periods, no regular command schedule is needed — the transponder stays active whenever the satellite is in sunlight.

Operators should always check real-time status via AMSAT Live Satellite Status, OSCAR Status pages, or recent community reports, as voltage instability in the aging satellite can occasionally cause unexpected behavior.

The scheduled activations for the eclipse period are:

May

1st 22:56~
2nd 22:00~
3rd 22:51~
4th 21:55~
5th 22:45~
6th 21:50~
7th 22:40~
8th 21:44~
9th 22:35~
15th 22:19~
16th 23:10~

Amateurs are reminded to:

  • Use proper Doppler correction.
  • Follow linear transponder etiquette (listen before transmitting, keep signals clean).
  • Limit uplink power to avoid overloading the transponder (typically no more than a few watts with a modest antenna).

The JARL page provides the detailed historical and upcoming command schedules for eclipse periods across 2025–2026. For the absolute latest status and any updates from the Japanese control team, monitor the official JARL FO-29 page, AMSAT.org, and AMSAT bulletins.

FO-29’s continued operation nearly 30 years after launch remains a testament to robust engineering and the dedication of the JARL team.

FCC Approves Limited Emergency Use of 70cm Band by AST SpaceMobile Satellites Outside the U.S.

The Federal Communications Commission (FCC) has granted AST SpaceMobile limited authorization when not over the United States to use five 50-kHz channels in the 430–440 MHz secondary amateur band for emergency Telemetry, Tracking, and Control (TT&C) operations for its planned satellite constellation (DA-26-391 Docket No. 25-201). The authorization, granted on April 21, 2026, applies only for communication with five specified earth stations, each located well outside of the United States and for which the foreign administration with jurisdiction also must separately authorize the communications.

More than 2,500 comments were filed during the proceeding including filings from ARRL and other member societies of the International Amateur Radio Union (IARU), AMSAT, and individual radio amateurs worldwide.

After considering the filed comments, the FCC narrowed the requested authorization to emergency TT&C only and further provided that:

  • Use of these frequencies is permitted only in emergencies when no other spectrum is available
  • Each emergency event is limited to no more than 24 hours
  • Transmissions are restricted to five specific center frequencies (430.5, 432.3, 434.1, 435.9, and 439.5 MHz), each with no more than 50 kHz bandwidth

In an April 29, 2026 statement, the IARU expressed concern with the FCC’s use of Article 4.4 of the ITU Radio Regulations, which allows administrations to authorize non-standard frequency use under certain conditions. The IARU stated that other frequency bands allocated for satellite TT&C should have been used instead of amateur spectrum and encouraged amateurs to report any interference to their national regulators.

ARRL filed comments (see ARRL News) in July (PDF) and August 2025 (PDF) opposing the application, arguing that:

  • The request represented an unprecedented use of secondary amateur spectrum for an unallocated use by a large commercial satellite constellation
  • Such operations could cause harmful interference, particularly to amateur satellites in the 435–438 MHz subband
  • The FCC should avoid authorizing non-allocated uses that could impact primary allocations for amateur services in other countries

While the FCC ultimately granted the authorization, it imposed the above significant limitations in response to these concerns that reduce the likelihood of interference.

In the U.S., reports of suspected interference to amateur spectrum can be shared with the ARRL Regulatory Information Manager, email [email protected].

ARRL will oppose any similar unallocated uses of spectrum used by amateurs that might cause harmful interference to amateur services and in particular will monitor this situation.

Request For Collecting CW Data of ARICA-2

ARICA-2, a 2U cubesat developed by Sakamoto Laboratory at Aoyama Gakuin University in Tokyo, was launched on April 23 by Rocket Lab in New Zealand.

The non-amateur mission goal of ARICA-2 is to demonstrate the real-time alert system of transient astronomical sources, such as gamma-ray bursts, using commercial satellite network services and to collect the images of the earth, and hopefully, aurora with a camera utilizing machine learning capability.

The amateur mission is to provide a “store and forward” capability using a 4k8 GMSK in AX25 format transceiver for communication among amateurs. The alert and housekeeping data are also broadcast through the amateur CW transmitter.

ARICA-2 is operating very stably, with no issues in its batteries or onboard equipment. Thanks to reception reports from amateurs worldwide, the Lab has been able to successfully receive CW signals from ARICA-2 every day, as well as GMSK signals triggered by uplinks from the Aoyama Gakuin university’s ground station.

At present, ARICA-2 is still undergoing satellite checkout procedures, and the amateur mission that will allow communication using GMSK has not yet started. Once the timing is appropriate to begin the amateur mission, the ARICA-2 team will announce it through amsat-bb and on X.

Until then, Sakamoto Laboratory would greatly appreciate the continued cooperation of amateurs in receiving the CW data, which contains housekeeping (HK) information from the satellite.

Here is the info about ARICA-2.

1. Preliminary TLE

ARICA-2 1 99999U 27001A 26113.16829861 .00000000 00000-0 00000-0 0

2. Frequency: 436.830 MHz (20 wpm CW)

3. The contents of the CW data and transmitting time are described at: https://sakamotolab.phys.aoyama.ac.jp/research/future_space/ARICA-2_en/cw_beacon.
Please also report the received CW data on that page.

Collection of the CW data of ARICA-2 is greatly appreciated!.

SDR Gen 2 Ad - 2026


NASA Completes Nancy Grace Roman Space Telescope

NASA has completed assembly of the Nancy Grace Roman Space Telescope, a next-generation observatory designed to map the universe on an unprecedented scale. Engineers at NASA’s Goddard Space Flight Center are finishing prelaunch testing before the spacecraft is shipped to Kennedy Space Center. Launch preparation is underway with a target as early as September, placing the mission ahead of its original schedule. Once deployed, Roman will operate from a distant orbit approximately one million miles from Earth.

The new telescope is designed to complement existing observatories such as the Hubble Space Telescope and the James Webb Space Telescope. While those missions focus on detailed observations of individual targets, Roman will conduct wide-field surveys, capturing images with similar resolution across areas roughly 100 times larger. This capability will allow astronomers to transition from isolated observations to large-scale mapping of cosmic structure. The result is expected to provide a broader context for many of the discoveries made by earlier space telescopes.

At the core of the mission is an eight-foot primary mirror paired with a powerful infrared imaging system. Roman’s wide field of view allows it to observe large regions of the sky in far fewer pointings than previous telescopes. For example, imaging the Andromeda Galaxy would require hundreds of individual exposures with Hubble but only a handful with Roman. This efficiency makes the observatory particularly well suited for large survey missions and time-domain astronomy.

One of Roman’s primary science goals is to study dark matter and dark energy, which together make up the majority of the universe. By mapping hundreds of millions of galaxies and measuring subtle distortions in their shapes, scientists can trace how invisible mass influences the structure of the cosmos. Observations of Type Ia supernovae will also help refine measurements of cosmic expansion. These combined datasets are expected to improve our understanding of the universe’s evolution and underlying physical laws.

The telescope will also expand the search for exoplanets using gravitational microlensing techniques. By monitoring dense star fields in the Milky Way’s central region, Roman can detect planets that orbit far from their host stars, including free-floating worlds. This approach complements earlier missions that focused on planets closer to their stars. In addition, Roman will test advanced coronagraph technology capable of blocking starlight to directly observe faint planetary companions.

Roman’s wide-field imaging capability will also support time-domain astronomy by repeatedly scanning large areas of the sky. These observations will capture transient events such as supernovae, black hole activity, and other short-lived phenomena. The resulting datasets will serve as a long-term reference for future discoveries, enabling astronomers to compare “before” and “after” views of dynamic regions of space.

SpaceX Rocket Debris to Impact The Moon

Earth’s moon is to be on the receiving end of a spent rocket stage in early August – the leftovers from a SpaceX Falcon 9 launch last year.

Firefly’s Blue Ghost Mission 1, named Ghost Riders in the Sky, launched on Jan. 15, 2025 and performed the first fully successful commercial lunar landing on March 2 at the moon’s Mare Crisium. That lander went on to mark the longest commercial operation on the moon to date.

Meanwhile, the Falcon 9’s leftover upper stage, labeled 2025-010D, that lobbed the two private spacecraft into space, is now headed for a run in with the moon. “We’ve been tracking it since launch. The orbit has changed a bit over the last year or so, and is now headed for a lunar impact,” said Bill Gray of Project Pluto.

Project Pluto provides software tools useful for astronomers to identify satellites in their data, and has published a page of data about the Falcon 9 upper stage.

He recalls that NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) mission back years ago did something very similar.

“We now have another upper stage due to hit the moon, this one on Aug. 5 and (just barely) on the near side of the moon,” Gray said.

Gray said he doesn’t expect this particular object to cause any trouble.

“It doesn’t present any danger to anyone,” said Gray, “though it does highlight a certain carelessness about how leftover space hardware is disposed of.”

The chance that rubble kicked up by the impact would hit a moon-circling spacecraft is quite small, said Gray, but he would factor that into any planned maneuvers.

“In a few years, things may be different,” Gray said, given humans tromping about on the lunar surface.

“That raises the stakes considerably. If I were sending an upper stage to high orbit, I would think about where it was going,” said Gray. You might launch an upper stage today, and then years later see a real problem, he said.

Changes to AMSAT TLE Distribution for May 1, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated 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/.

The following satellites have been added to this week’s AMSAT TLE Distribution:

MAGNARO-II-Piscis is object 68798 (2026-088G). Frequency: 436.326 MHz.
ARICA 2 is object 68796 (2026-088E). Frequency: 436.830 MHz.
FSI-SAT 2 is object 68792 (2026-088A). Frequency: 437.176 MHz.
WASEDA-SAT-ZERO-II is object 68797 (2026-088F). Frequency: 437.205 MHz.
OrigamiSat 2 is object 68795 (2026-088D). Frequency: 437.506 MHz.

General Perturbations Data Support

AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.

These data are presently considered in beta test for the next two months while hosted on the test server newark192.amsat.org, and we are very open to community feedback at [email protected]. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

Artemis 2 Moon Astronauts Visit the White House

President Trump invited the Artemis 2 quartet and NASA Administrator Jared Isaacman to the Oval Office today (April 29), for a livestreamed press event that the White House described as a “greeting.”

“It takes people like this to make our country great,” Trump said of the crew. “We’re very proud of these people. They have unbelievable courage.”

Artemis 2 launched on April 1 and returned to Earth on April 10. The mission sent Reid Wiseman, KF5LKT, Victor Glover, KI5BKC, Christina Hammock Koch, and Canadian astronaut Jeremy Hansen, KF5LKU, on an epic journey around the moon and back. They were the first people to leave Earth orbit since the Apollo 17 astronauts in 1972, and they got farther from their home planet than anyone ever has before, breaking the record set by Apollo 13 in 1970.

Satellite Shorts from All Over

+ The Iowa State University Campus Amateur Radio Club (WØISU) will be launching a 10 kHz wide non-inverting linear transponder on May 2nd at 1300z on a high altitude balloon. All info for this flight can be found at this website: https://stuorgs.engineering.iastate.edu/carc/balloon-lauch/. The transponder will have a 10m uplink and a 2m downlink. NOTE: There is always a chance that the balloon launch may be cancelled due to weather. The backup launch day will be Sunday, May 3rd. Please see the linked website for updates regarding cancellation of the launch. Please contact me if you have any questions. (ANS thanks Kees Van Oosbree, WØAAE, for the above information.)

+ The hatches are open between the International Space Station and the new Progress 95 cargo spacecraft following the delivery of about three tons of food, fuel, and supplies on Monday. Expedition 74 commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev, both from Roscosmos, finalized leak and pressure checks between Progress 95 and the Zvezda service module’s rear port on Tuesday. Afterward, the duo installed air ducts and began unpacking the spacecraft beginning seven months of cargo activities in the resupply ship. (ANS thanks NASA for the above information.)

+ AST SpaceMobile has received the green light to operate satellite-to-phone services in the US, setting the stage for the company to compete against SpaceX’s Starlink Mobile. On April 21, AST secured FCC approval to operate the entirety of its 248-satellite constellation and offer “supplemental coverage from space,” including outside the U.S. (ANS thanks PC Magazine for the above information.

+ SpaceX’s most powerful operational rocket, the Falcon Heavy, lifted off Wednesday carrying a massive communications satellite on its 12th flight since 2018. The 27 Merlin engines of the three Falcon boosters roared to life at 1413 UTC and the 70-meter-tall (229.6 ft) rocket thundered away from Launch Complex 39A propelled by 5 million pounds of thrust. Deployment of the satellite came at nearly five hours after liftoff. The upper stage featured an additional thermal protection layer to ensure the fuel, a rocket-grade kerosene, does not freeze during the roughly four-hour coasting phase between the second and third engine ignitions. The ViaSat-3 F3 satellite is the second in the series to be launched onboard a SpaceX Falcon Heavy rocket and the third and final member of this constellation. The first satellite, ViaSat-3 Americas, launched on a Falcon Heavy rocket in 2023. (ANS thanks Spaceflight Now for the above information.

Digital Modes on FO-29 Not Permitted per Licensing Restrictions

Fuji-OSCAR 29 (FO-29 / JAS-2), the Japanese amateur radio satellite launched in August 1996, has entered a period of full sunlight, resulting in renewed and more frequent transponder activity. The inverting analog transponder operates with an uplink passband of 145.900–146.000 MHz (LSB) and a downlink of 435.800–435.900 MHz (USB), along with a CW beacon at 435.795 MHz. The satellite’s 1-watt PEP output is shared across the 100 kHz bandwidth, making careful power management essential for all users.

Although the FO-29 linear transponder is technically capable of passing narrowband digital signals such as FT8, FT4, PSK31, or Olivia, such operations are not permitted under the satellite’s original licensing from Japanese authorities. The transponder is explicitly licensed for SSB and CW modes only. This restriction stems from the satellite’s operational permit issued by Japan’s Ministry of Internal Affairs and Communications (MIC), which does not authorize digital emissions on the linear transponder frequencies.

Japanese license information indicating emission modes A1A (CW) and J3E (SSB)
are the only modulations permitted in the linear transponder downlink.

Operators attempting digital modes risk non-compliance with international amateur radio etiquette and could contribute to transponder overload, distortion, or temporary shutdowns—issues exacerbated by the high-duty-cycle nature of many digital signals.

AMSAT urges all users to limit their operations on FO-29 to SSB and CW and to practice good satellite etiquette:

  • Use the minimum power necessary to produce a readable downlink signal.
  • Ensure your downlink signal strength does not exceed the CW beacon level.
  • Monitor the transponder before and during your transmission; if the beacon weakens or the passband becomes noisy, reduce power immediately.
  • Keep signals clean and within the passband.

Share the limited resource responsibly so that the maximum number of amateurs worldwide can enjoy FO-29 while it remains active.

With the satellite now enjoying extended full-sunlight operation in 2026, this is an excellent time to explore its capabilities through permitted modes. Experimentation with unauthorized modes is discouraged to preserve the satellite’s health and comply with licensing.

Ten-Koh 2 Satellite With Linear Transponder Update

The 6U CubeSat Ten-Koh 2 (also written as Tenkoh-2 or てんこう2) from Japan’s Nihon University was successfully deployed into orbit on March 11, 2026, at approximately 09:34 UTC. The satellite was released from JAXA’s new HTV-X1 cargo spacecraft using the HTV-X Small Satellite Orbital Deployer (H-SSOD) after the vehicle departed the International Space Station (ISS) on March 6 and raised its altitude to around 500 km. This marks the first use of the H-SSOD mechanism for satellite deployment from HTV-X.

Developed by the Okuyama Laboratory in the Department of Aerospace Engineering at Nihon University’s College of Science and Technology, Ten-Koh 2 builds on the legacy of its predecessor, Ten-Koh (launched in 2018). The mission focuses on low-Earth orbit environmental observations to gather data for future space development, alongside in-orbit demonstrations of next-generation communication technologies. Key goals include evaluating high-speed data transmission and enabling global access for amateur radio operators to collect telemetry and experiment with the payloads.

The satellite carries an amateur radio payload coordinated by the International Amateur Radio Union (IARU) and supported by JAMSAT (Japan Amateur Satellite Association):

V/U Linear Transponder (inverting, 40 kHz bandwidth):
     Uplink (LSB): 145.895–145.935 MHz
     Downlink (USB): 435.875–435.915 MHz
Additional Downlinks/Experiments:
     CW beacon, Digitalker, AFSK 1.2 kbps, GMSK up to 19.2 kbps on 435.860 MHz
     High-speed experiments (GMSK 4.8–19.2 kbps, 4FSK 38.4 kbps) and photo/picture downlinks on 435.895 MHz
     5.839 GHz CW beacon for microwave-band communication demos (SHF experimenters take note—this provides a great target for testing dishes, feeds, and LNAs)

The transponder is expected to operate on a scheduled basis (initially two days per week, with details forthcoming from the team). Operations began shortly after deployment, with the university’s ground station confirming reception of the CW beacon for basic telemetry (voltage, temperature, etc.).

Post-deployment updates from the Okuyama Lab indicate the signal level is currently weaker than anticipated, prompting ongoing monitoring and appeals for reception reports via networks like SatNOGS to aid diagnostics and performance assessment. Early passes over Japan and other regions have yielded mixed results, with some operators reporting no signals yet. Ten-Koh 2 currently only transmits very weak CW data on 435.860 MHz.

Ten-Koh 2 Keplerian data (TLE) are now available in the regular satellite catalog under catalog number 68261.

SpaceX Plan For 1 Million Centers Poses Dangerous Risk

A SpaceX plan for 1 million orbital data centers proposes a massive constellation of sunlit objects that could severely impair ground-based astronomy and increase atmospheric pollution through frequent reentries in the upper atmosphere.

Astronomers warn that these 100-meter-long structures will remain illuminated even at midnight. This constant visibility threatens observations at ground-based observatories, such as the Vera Rubin Observatory and the Extremely Large Telescope currently under construction in Chile.

These orbital data centers, potentially 100 meters long, create persistent light streaks that obstruct astronomical research. Positioned in high-inclination orbits at 500-2,000 km, they remain illuminated by sunlight even at midnight, significantly outshining traditional broadband satellites.

Astronomers have filed formal objections with the FCC regarding the January 30 application. This new constellation poses a challenge unlike any encountered in the commercial space era, undermining years of progress.

Further, this much hardware results in one spacecraft burning up in the atmosphere every three minutes. This mass incineration releases dangerous concentrations of aluminum oxide and lithium, potentially depleting the protective ozone layer and altering global temperatures.

Environmental experts highlight risks, but the FCC’s fast-track approval process bypasses standard environmental reviews, placing the burden of proof on the scientific community to prevent damage.

Astronauts Complete Prep For New ISS Solar Array

Two NASA astronauts prepared the International Space Station (ISS) for the addition of a new solar array on the first U.S. spacewalk in almost a year.

Expedition 74 crewmates Jessica Meir and Chris Williams, KJ5GEW, ventured outside of the space station’s Quest airlock at 1252 UTC on Wednesday, March 18 to install a mount for an advanced power-producing solar panel. The pair worked on the left (or port) side of the space station’s backbone truss, where they first assembled and then attached the bracket structure that will support an ISS Roll-Out Array (iROSA), to be installed on a future spacewalk.

a spacewalk on Wednesday, March 18, 2026. (Image credit: NASA)

NASA had scheduled for the iROSA kit to be installed during a spacewalk in January, but one of the then-assigned spacewalkers, Mike Fincke, KE5AIT, had an undisclosed medical issue that required the excursion to be canceled and he and his crewmates to return to Earth a month early.

The space station’s original solar arrays have degraded, having exceeded their 15-year service life. When all of them are in place, the new iROSAs will increase the orbiting lab’s electricity supply by 20% to 30%. The additional power on the ISS will help support expanded commercial activities and the upcoming transition from the ISS to commercially operated space stations.

Wednesday’s spacewalk ended at 19:54 UTC, 7 hours and 2 minutes after it began.

Kairos No. 3 Launch Failure Destroys NUTSAT-3

The third time was not the charm for Space One’s Kairos rocket.

Kairos launched for the third time ever on Thursday, March 5, lifting off from Space One’s Spaceport Kii in Wakayama Prefecture at 02:10 UTC (11:10 a.m. local time in Japan). But it was all over about two minutes later.


Space One’s Kairos rocket launches on its third-ever mission on March 4, 2026 from Spaceport Kii.

“Kairos No. 3 was launched on March 5, 2026, at 11:10:00 a.m., but we determined that mission success was difficult and implemented flight termination measures,” Tokyo-based Space One said via X on Wednesday evening (in Japanese; translation by X).

Among the Kairos No. 3 payloads was NUTSAT-3, a 3U CubeSat created with support from National Formosa University and dedicated to amateur radio service. The satellite, was designed to provide FM voice repeater, APRS, and telemetry services to the global amateur satellite community.

In addition to the amateur radio mission, the NUTSAT-3 project was to have actively engaged students in mission data analysis, RF design performance of satellite radio communications, and community participation by encouraging public engagement through open telemetry data.

Ten-Koh 2 to be Deployed Soon

A Japanese amateur radio satellite, launched to the International Space Station (ISS) last October, will soon be deployed in a higher orbit.

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.

Cambodian Students Blast Off With Satellite Training

Although space technology may have not been officially introduced into the Kingdom’s standard curriculum, the topic is taking center stage at the National Polytechnic Institute of Cambodia (NPIC), at the 2nd Session of the NPIC SCT Event: QO-100 and LEO Satellite Training, igniting a passion for space communication among students.

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.

“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.

Changes to AMSAT-NA TLE Distribution for March 6

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated 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

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.

Satellite Shorts From All Over

+ In a statement on March 3, the Russian space agency Roscosmos said that its engineers have repaired a badly damaged launch pad at the Baikonur cosmodrome ahead of schedule, averting a potentially longer-term problem for supplying the International Space Station (ISS). 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. See the full article at https://spaceflightnow.com/2026/03/03/live-coverage-spacex-to-launch-29-starlink-satellites-on-falcon-9-rocket-from-cape-canaveral-10/.)

+ NASA announced on February 19 that it has reclassified Starliner’s Crew Flight Test (CFT) as a “Type A mishap” — the most serious kind, in the same category as the space shuttle Challenger and Columbia tragedies. 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.

FO-29 Approaches Full Sunlight

Fuji-OSCAR 29 (JAS 2) will soon enter a season of orbits in full sunlight, making it once again available for worldwide use.

JAS-2 was successfully launched on August 17, 1996. It orbits the Earth in a polar orbit at 1300 km altitude in a time of 112 minutes. The inclination is 98°. The transmission power of the beacon is 100 mW, the transponder 1 watt. The linear transponder downlink is from 435.800 MHz – 435.900 MHz (USB, CW), with uplink from 145.900 MHz – 146.00 MHz (LSB, CW). CW beacon frequency is 435.795 MHz.

Fuji-OSCAR 29 (JAS 2) Credit: JAMSAT

Designated as Fuji-OSCAR 29 after achieving orbit, JAS 2 has long been one of the most popular and most useful linear satellites available to amateurs. However, as the satellite approaches 30 years of age, its batteries have long-since failed. It only continues to operate while the sun is illuminating its solar panels.

On March 9, FO-29 will begin orbiting in full sunlight, without periodic eclipses.

In mid-February, the duration of the shadow decreases from about 20 minutes to about 1 minute per day. Therefore, FO-29’s transmitter may suddenly come to life unexpectedly. Amateurs are encouraged to monitor the satellite and to update its activity on the AMSAT OSCAR Satellite Status page, https://www.amsat.org/status/.

Please enjoy using FO-29 while it remains available!

SpaceX Grounds its Falcon 9 Rocket

SpaceX has temporarily grounded its workhorse Falcon 9 rocket, which is slated to launch four astronauts next week.

A Falcon 9 delivered 25 of SpaceX’s Starlink satellites into low Earth orbit (LEO) as planned on Monday (Feb. 2). But, after deploying the payloads, the rocket’s upper stage failed to perform its deorbit burn, which was designed to bring it down for controlled destruction in Earth’s atmosphere.

to the International Space Station in September, 2025. Credit: NASA+

The Falcon 9 is the world’s busiest rocket by far. It launched a record-breaking 165 times in 2025 and already has 14 liftoffs until its belt this year.

The rocket is incredibly reliable, too. All of last year’s missions were successful, and just a single one — a Starlink launch on March 3 — experienced a significant anomaly.

It’s unclear how long this new launch hiatus will last. But both SpaceX and NASA doubtless hope the issue is resolved soon, for a very high-profile Falcon 9 launch is coming up — that of the Crew-12 astronaut mission to the International Space Station (ISS).

Crew-12 is scheduled to include NASA astronauts Jack Hathaway, KJ5NIV, and Jessica Meir, as well as French astronaut Sophie Adenot, KJ5LTN, and Russian cosmonaut Oleg Artemyev. Their SpaceX Dragon capsule has been scheduled for launch atop a Falcon 9 rocket on February 11.

Declassifying JUMPSEAT: An American Pioneer in Space

The director of the National Reconnaissance Office (NRO) recently declassified the existence of JUMPSEAT: the United States’ first-generation, highly elliptical orbit (HEO) signals-collection satellite.

Launched from 1971 to 1987 under mission numbers 7701 to 7708, JUMPSEAT was the product of the United States Air Force’s (USAF) program at the NRO. Developed under a program called “Project EARPOP,” JUMPSEAT offered the U.S. a way of collecting intelligence during unprecedented geopolitical change and Cold War tensions that lasted until the early 1990s.

JUMPSEAT Model_2_1 Credit: NRO

The NRO and USAF, collaborating as a part of NRO’s “Program A,” were tasked with developing a foundational HEO signals collection satellite to bolster the U.S. government’s space intelligence portfolio. Named JUMPSEAT, the new satellite would be capable of operating in a highly ellipical, or Molniya, orbit. [Editor’s Note: These orbits are very similar to those that were used by amateur radio satellites AO-10, AO-13, and AO-40 in the 1980s and -90s.]

Together, the NRO and the USAF launched the first JUMPSEAT mission in 1971 from Vandenberg Air Force Base (now Vandenberg Space Force Base) in California. Once in orbit, JUMPSEAT successfully collected electronic emissions and signals, communication intelligence, and foreign instrumentation intelligence: invaluable information that was downlinked to ground processing facilities within the U.S. From there, the data was provided to the Department of Defense, the National Security Agency, and other national security elements.

Over the decades, JUMPSEAT satellites continued to prove their worth to signals intelligence, finally operating in transponder mode until they were taken out of service in 2006.

Kenya to Represent Africa in ARISS Program 2026

Kenya is set to make history in 2026 after being selected to host the Amateur Radio on the International Space Station (ARISS) program, a global initiative that enables the public to communicate live with astronauts aboard the International Space Station (ISS).

The Kenya Space Agency announced the selection, positioning the country at the heart of an international effort to advance space education and public engagement in science. Kenya is the only African nation chosen for the 2026 ARISS cycle, a milestone expected to spark interest in science, technology, engineering and mathematics (STEM) and inspire innovation across the country.

According to the agency, the hosting window will run between July and December 2026. During this period, Kenyan students, professionals and members of the public will take part in live radio sessions with astronauts on the ISS. Participants will have the opportunity to ask questions and receive real-time answers about daily life in orbit, scientific research conducted on board and the realities of living and working in space.

The Kenya Space Agency will oversee preparations for the event in collaboration with Pan-African Citizen Science e-Laboratory mentor and agency liaison Harold Safary. Planning efforts will include technical coordination, public outreach and the selection of participants, with an open call to be issued for interested individuals and institutions wishing to take part in the live ISS contacts.

The 2026 ARISS program will offer Kenyans a rare opportunity to speak directly with astronauts aboard the ISS, marking a significant step in the country’s engagement with global space initiatives and space education.

The packet system (145.825 MHz up & down) was scheduled for repair on February 5.

Ham TV (2395.00 MHz) is configured for scheduled digital amateur television operations.

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

Satellite Shorts from All Over

+ In September 2025, AMSAT-DL and the Bochum Observatory jointly organized the “Bochum Space Days 2025” conference in the radome under the 20-metre antenna. The Radom was all about satellite and space research. A varied and informative program was offered, aimed at AMSAT members as well as all space enthusiasts and makers. The presentations are now available on the AMSAT-DL YouTube channel. The language of the presentation is mixed German/English and subtitles can also be optionally activated in the respective translation. Begin at https://www.youtube.com/watch?v=IW384KY6lBo&list=PLbIhjH2wj12GfMJGRwbYPFEjU7ECtjzzO (ANS thanks AMSAT-DL for the above information.)

+ The National Oceanic and Atmospheric Administration (NOAA) Space Weather Follow On – Lagrange 1 (SWFO-L1) satellite has reached its final destination—nearly one million miles away from Earth toward the sun and has been renamed SOLAR-1. The observatory is expected to begin space weather operations in Spring 2026. Read more at http://bit.ly/4bUIY1K. (ANS thanks NOAA for the above information.)

+ Edge of Space Sciences, a ham radio club in Englewood, Colorado, has been monitoring three amateur radio pico balloons as they continue to circumnavigate the globe. Two balloons were released at HamCon Colorado on October 25, 2025. EOSSP-3 has completed 5 circumnavigations and is currently lost somewhere “up north.” No signal has been heard for 4 days. EOSSP-4 has completed 7 circumnavigations and is currently approaching India. Meanwhile, EOSSP-2, launched September 18, completed its 10th circumnavigation at 19:05 UTC on February 4. The balloons can be tracked on aprs.fi at https://aprs.fi/#!call=a%2FEOSSP-2%2Ca%2FEOSSP-4%2Ca%2FEOSSP-3&timerange=259200&tail=86400. More information can be found on the club’s website, www.eoss.org. (ANS thanks ARRL for the above information.)

+ NASA is no longer planning a February launch of the Artemis 2 mission after encountering hydrogen leaks during a fueling test of the Space Launch System. In a statement early Feb. 3, NASA said it completed a wet dress rehearsal for Artemis 2 but determined the vehicle will not be ready to launch during the February window, which closes Feb. 11. Several other issues occurred during the test. A valve in Orion’s hatch pressurization system was accidentally vented during closeout work, requiring additional time to repressurize the system. Unseasonably cold temperatures, which had already delayed the rehearsal by two days, caused further issues, including delays in tanking operations and problems with cameras and other pad equipment. NASA also reported intermittent audio dropouts in communications among ground teams. The next launch period for Artemis 2 runs from March 6 to 11, with five two-hour windows available. Another launch opportunity extends from April 1 to 6. (ANS thanks SpaceNews for the above information. Read the full article at https://spacenews.com/artemis-2-slips-to-march/)
