After just over six years in orbit, Fox-1D, designated as AMSAT-OSCAR 92 (AO -92), likely re-entered the Earth's atmosphere on February 3, 2024 (Space-Track had not issued the final decay message as of the time of this writing.)
AO-92 was a 1U CubeSat developed and built by AMSAT. It carried a single-channel transponder for mode U/v in FM and also had an L-band converter (the AMSAT L-band downshifter experiment), which allowed the FM transponder to be switched to an uplink in the 23 cm band.
In addition to the transponders, the satellite carried the following scientific and technical payloads:
- High Energy Radiation CubeSat (HERCI) built by the University of Iowa - Camera Experiment built by Virginia Tech - MEMS GYRO Experiment built by Penn State-Erie
The satellite had a single whip antenna for the 70 cm and 23 cm bands (uplink), as well as an antenna for the 2m band (downlink).
AO-92 was launched on January 12, 2018 at 03:59 UTC on an Indian PSLV XL rocket, along with the main payloads Cartosat-2F, NovaSAR-S, and 31 other small satellites from the Satish Dhawan Space Center, India. At 05:17 UTC, the antennas were deployed over the North Pole and the satellite began to operate. At 05:28 UTC the first telemetry was received.
On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced that AO-92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO-92 was open for amateur use.

In addition to a very popular U/v transponder, the satellite provided a couple of unique capabilities. First was the L-band downshifter experiment, which was generally activated for 24 hours each Sunday while the satellite was able to support it. Pre-launch estimates suggested that approximately 100 watts ERP would be required to access the satellite, but much lower power outputs proved to be usable. Many stations operated through the satellite with radios such as the Alinco DJ-G7T at 1 watt of output into handheld antennas of between between 10 and 16 elements. At least one station reported accessing the satellite with just a simple whip antenna on 23 cm.
The camera, developed by students at Virginia Tech, also proved to be popular and delivered many good pictures, with the last photos received on September 19, 2020. An archive of all of the photos captured by ground stations can be found at https://www.amsat.org/tlm/showImages.php?id=4. https://www.amsat.org/tlm/showImages.php?id=4
The distance record on AO-92's U/v mode was 5,011 km - a transatlantic QSO between F4DXV and VE1VOX that took place on August 10, 2020. The record via the L/v mode was 4,202 km between OA4/XQ3SA and XE1MEX on June 3, 2020.
By early 2021, the aging NiCd cells - having been purchased in the early 2010s along with the rest of the Fox-1 battery cells - had degraded to the point where the satellite was entering safe mode on every eclipse. It was rarely operational in recent months. The transponder was occasionally turned on, but usually defaulted into "Safe Mode" at the next eclipse. The last telemetry frame was received from the satellite on October 27, 2023 at 01:36 UTC.
By every measure, AO-92 was a tremendously successful amateur radio satellite, providing educational and research benefits to AMSAT's university partners, as well as providing several years of reliable FM communication for amateurs. Its useful life far exceeded the average operational lifespan for commercial or educational CubeSats.

*A rendering of the Smart Lander for Investigating Moon (SLIM) on the lunar surface. [Japan Aerospace Exploration Agency, image]*
The Japan Aerospace Exploration Agency (JAXA) successfully landed their Smart Lander for Investigating Moon (SLIM) on January 19, 2024. Just before touchdown, SLIM released two small lunar surface probes, LEV-1 and LEV-2.
LEV-2 collects data while moving on the lunar surface, and LEV-1 receives the data.
The JAXA Ham Radio Club (JHRC), JQ1ZVI, secured amateur radio license JS1YMG for LEV-1, which has been transmitting Morse code on 437.41 MHz since January 19. The probe uses a 1 W UHF antenna with circular polarization and is transmitting "matters related to amateur business."
Radio amateurs have been busy analyzing JS1YMG's signal, with Daniel Estévez's, EA4GPZ, blog https://destevez.net/2024/01/trying-to-decode-lev-1/ introducing the method and extraction results for demodulating Morse code from the signal, as well as extracting the code string.
It's unclear how long signals will be heard. JAXA has said that SLIM was not designed to survive a lunar night, which lasts about 14 days, and is due to return in a few days.
SLIM was launched on September 6, 2023, and landed on January 19, 2024, with the mission of analyzing the composition of rocks to aid research about the origin of the moon. SLIM's landing made Japan the fifth country to achieve a soft touchdown on the moon. The landing was achieved with exceptional precision -- within 180 feet of its targeted touchdown location.

https://www.amsat.org/join-the-amsat-presidents-club/2024-coin-both_586/#main ------------------------------ Lunar Excursion Vehicle (LEV-1) Amateur Telemetry Received
The Japan Aerospace Exploration Agency (JAXA) confirmed on January 20, 2024, that the Lunar Excursion Vehicle (LEV-1), a small robot deployed from the Smart Lander for Investigating Moon (SLIM), successfully conducted activities on the lunar surface. The telemetry data were sent directly from the small robot.
According to telemetry data, after deployment from SLIM, LEV-1 executed planned leaping movements and direct communication with ground stations, including inter-robot test radio wave data transmission from the Transformable Lunar Robot (LEV-2, nicknamed "SORA-Q"). On the other hand, image acquisition on the lunar surface has not been confirmed as of now.
Currently, LEV-1 has completed its planned operational period on the lunar surface, depleted its designated power, and is in a standby state on the lunar surface. While the capability to resume activity exists contingent on solar power generation from changes in the direction of the sun, efforts will be maintained to continue receiving signals from LEV-1.
Both LEV-1 and LEV-2 have become Japan's first lunar exploration robots. Additionally, the small LEV-1 with a mass of 2.1 kg (including a 90g communication device), achieved successful direct communication with Earth from the moon. This is considered as the world's smallest and lightest case of direct data transmission from approximately 380,000 kilometers away.
Furthermore, the accomplishment of LEV-1's leaping movements on the lunar surface, inter-robot communication between LEV-1 and LEV-2, and fully autonomous operations represent groundbreaking achievement. It would be regarded as a valuable technology demonstration for future lunar explorations, and the acquired knowledge and experience will be applied in upcoming missions.
Moreover, the transmission of UHF band radio waves from LEV-1 as part of outreach efforts has encouraged participation from amateur radio operators globally, and we have been receiving reports of successful signal receptions. This initiative provided an opportunity for the public to be directly engaged in lunar exploration missions. We would like to extend our sincere gratitude to everyone involved in the LEV-1 mission.
LEV-1 has an International Amateur Radio Union (IARU) coordinated downlink frequency of 437.410 MHz. A detailed report on receiving and decoding LEV-1 telemetry has been prepared by Daniel Estevez, EA4GPZ/M0HXM. It can be found at https://destevez.net/2024/01/trying-to-decode-lev-1/ An earlier summary of LEV-1 design and specifications is at https://robotics.isas.jaxa.jp/lev /LEV_HAM_Club.html.

------------------------------ Request to Reconsider Decommissioning of IO-117 Under Evaluation by Italian Space Agency
On Thursday, January 25, 2024 S5Lab posted on X that the GreenCube (IO-117) Digipeater would be permanently deactivated on February 5th.
Designed and developed by students of Sapienza University of Rome, IO-117 is the first satellite to carry an amateur radio payload into a Medium Earth Orbit (MEO) of approximately 6,000 km.
The message from S5Lab read:
*Dear Friends,*
*After one year and a half of operations, it is time to conclude the GreenCube operations with the planned de-commissioning activities. After the conclusion of the nominal experiment and with the digipeater payload active for more than one year, we will perform the passivation operations for the satellite.*
*The planned passivation operations will be executed on Monday, 5 February 2024, at 00:00 UTC. From that day, GreenCube will be completely passivated and the digipeater will be switched off for good.*
*We want to thank everyone that endorsed, supported or participated in the mission and the radio amateur community that enthusiastically became a true part of our project. We hope that GreenCube will somehow be part of your memories of radio amateurs, space engineering enthusiasts, and we hope to involve you soon in many more adventures.*
*Thanks once again for the unbelievable memories shared together… See you soon!*
*The GreenCube Team at S5Lab*
That afternoon, AMSAT sent a letter to S5Lab https://www.amsat.org/amsat-responds-planned-decommissioning-io-117-greencube/ expressing the organization's desire to leverage our decades of experience and work with S5Lab, AMSAT Italia, other AMSAT organizations, and the amateur satellite community at large to overcome any obstacles, regulatory or otherwise, to keeping IO-117 in service for as long as possible. AMSAT-DL, AMSAT-F, and other amateur satellite organizations also expressed similar sentiments. Peter Goodhall, 2M0SQL, began a petition on change.org https://www.change.org/p/save-the-greencube-satellite-digipeater that garnered over 1,500 signatures from amateur radio operators around the world in one week.
On the afternoon of Friday, February 2, 2024, AMSAT Italia made the following announcement:
*AMSAT Italia would like to inform the amateur community that its request to the Italian Space Agency, the owner of the GREENCUBE satellite, to reconsider its decision of decommissioning the satellite is under evaluation.*
*Waiting for its decision, IO-117 is still operational.*
*The GreenCube satellite was born as a scientific experiment placed in MEO orbit which successfully concluded its mission.*
*IO-117 is the HAM Radio part of the satellite consisting of a digipeter which was promoted by AMSAT Italia and coordinated by IARU-R1.*
*At the moment AMSAT Italia is committed to promoting the continuation of the mission for the HAM Radio part of Greencube.*
*AMSAT Italia BoD*
During its lifetime, IO-117 has proved to be a popular resource, allowing amateurs all over the world to obtain ARRL's Worked All States (WAS) and DX Century Club (DXCC) awards via satellite and to boost their VHF/UHF Century Club (VUCC) grid totals. A strong presence by Japanese amateurs has allowed many to work all the Japanese prefectures. A few DXpeditions, such as TX5S to Clipperton Island, have also brought gear for IO-117 along and provided rare DX entities via satellite. Multiple future DXpeditions also plan IO-117 activities. AMSAT is hopeful that the satellite's lifetime can be extended.
