NASA Selects Global Tracking Volunteers for Artemis II Lunar Mission

NASA has selected 34 volunteer organizations and individuals from around the world to help track the Orion spacecraft during the upcoming crewed Artemis II mission, which will carry four astronauts on a journey around the Moon. The selected participants include commercial service providers, universities, government agencies, nonprofit organizations, and individual amateur radio operators, reflecting a broad international collaboration supporting humanity’s return to deep space.

While NASA’s Near Space Network and Deep Space Network will provide primary communications and navigation support, the volunteers will passively track radio signals transmitted by Orion during its approximately 10-day mission. Participants were chosen from proposals submitted in August 2025. They will submit tracking data to NASA for analysis, helping the agency evaluate broader aerospace and amateur radio tracking capabilities. No funding is exchanged as part of this collaborative effort.

“This is a real step toward SCaN’s commercial-first vision,” said Kevin Coggins, NASA’s deputy associate administrator for Space Communications and Navigation (SCaN). “By inviting external organizations to demonstrate their capabilities during a human spaceflight mission, we’re strengthening the marketplace we’ll rely on as we explore farther into the solar system. This isn’t about tracking one mission, but about building a resilient, public-private ecosystem that will support the Golden Age of innovation and exploration.”

The initiative builds on a similar effort during Artemis I in 2022, when 10 volunteers successfully tracked Orion and provided valuable lessons on data formatting, quality, and standards compliance. For Artemis II, SCaN now requires all submitted tracking data to meet its system standards. Public interest has increased significantly, with about 47 ground assets across 14 countries expected to support the mission.

Amateur radio organizations and enthusiasts are well represented in the selected group. Participants include AMSAT Argentina, AMSAT Deutschland, the Amateur Radio Exploration Ground Station Consortium, CAMRAS in the Netherlands, the Deep Space Exploration Society in Colorado, and several individual operators, including Scott Tilley of Canada. Their involvement highlights the growing technical capability of the global amateur radio community to contribute meaningfully to deep-space missions.

Although NASA has formally selected a limited group to submit official tracking data, anyone with appropriate equipment can attempt to track Artemis II independently, either by monitoring Orion’s radio emissions or by observing the spacecraft optically with a telescope during its trans-lunar coast. NASA has emphasized that it is simply accepting data from a designated group and is not restricting independent observation. For amateur astronomers and radio operators alike, Artemis II offers a rare opportunity to witness — and participate in — humanity’s return to deep-space exploration.

Thailand’s KNACKSAT-2 CubeSat Preparing for Deployment from the ISS

Thailand’s KNACKSAT-2 satellite is preparing for deployment from the International Space Station, with release currently scheduled for February 3, 2026 at 08:55 UTC (03:55 AM EST). The mission continues Thailand’s university-led CubeSat development program following the earlier KNACKSAT-1 mission. The project is led by King Mongkut’s University of Technology North Bangkok in Thailand, working with domestic and international partners to advance satellite engineering, payload integration, and on-orbit operations. The deployment is expected to be viewable live online via the project livestream at https://www.youtube.com/watch?v=aB4PIOS-hSs.

KNACKSAT-2 was transported to the International Space Station in late 2025 and is a 3U CubeSat designed to host multiple payloads. The satellite expands on KNACKSAT-1, which demonstrated Thailand’s ability to design and build a satellite domestically. Development and testing were conducted in cooperation with NBSPACE and other academic and research partners. The mission is intended to help Thailand develop multi-payload CubeSat platforms and prepare for future ride-share launch opportunities.

The satellite carries both educational and research payloads. Non-amateur missions include an Earth imaging camera, a store-and-forward IoT data collection system for remote sensors, ultraviolet radiation measurement instrumentation, and in-orbit evaluation of space-qualified components. These payloads are part of broader national workforce development programs coordinated through the Thai Space Consortium and academic partner networks. The satellite will be operated in orbit using ground stations located in Thailand.

KNACKSAT-2 also supports amateur radio operations through an APRS digipeater payload developed in cooperation with the Radio Amateur Society of Thailand. The amateur payload operates using coordinated frequencies through the International Amateur Radio Union (IARU) satellite frequency coordination process. The APRS digipeater system uses 145.825 MHz for uplink and downlink using FSK modulation at 9600 bps with AX.25 framing. The amateur satellite callsign assigned to the mission is HSØK.

In addition to amateur payloads, the spacecraft transmits engineering telemetry on 400.630 MHz using FSK at 9600 bps with AX.25 framing and a one-minute beacon interval. Following deployment, project coordinators have requested assistance from the monitoring community to receive, decode, and submit telemetry reports from the 400.630 MHz downlink, which is outside the amateur radio allocation. Many satellite observers actively search for newly deployed spacecraft and contribute reception reports, helping mission teams verify spacecraft health and early on-orbit performance. The satellite is expected to rotate in orbit, and ground stations are recommended to use circular polarization, with RHCP preferred, to improve reception reliability.

KNACKSAT-2 continues the growing trend of university-driven satellite programs contributing technical capability, education, and operational experience to the global amateur satellite community. University-built satellites are playing an increasing role in expanding access to space while supporting educational outreach and new opportunities for amateur radio experimentation.

Open.Space Phased Array Project Targets Low-Cost EME for Hams

An upcoming open-source hardware project called Open.Space aims to lower the barrier to Earth-Moon-Earth (EME) communications for amateur radio operators by using a modular, software-defined phased-array system instead of traditional large dish antennas. EME, or moonbounce, involves transmitting a signal toward the Moon, reflecting it off the lunar surface, and receiving it back on Earth. Historically, this has required large high-gain antennas, high-power transmitters, and precise mechanical tracking, putting it out of reach for many amateurs.

Open.Space proposes using electronically steerable phased arrays built from small, low-cost software-defined radio (SDR) tiles. A phased array combines the signals from many small antennas using precise timing delays, allowing radio beams to be steered electronically without motors or moving parts. This enables rapid tracking, improved interference rejection, and compact, low-profile installations. A familiar consumer example of phased-array technology is the flat-panel antenna used by Starlink satellite internet terminals.

At the core of the system is the Open.Space Quad tile, a 4-antenna SDR module covering 4.9 to 6.0 GHz in the C-band. Each tile supports 40 MHz of bandwidth using an 8-bit ADC and delivers about 1 watt of transmit power per antenna. The tiles can operate as standalone 4×4 MIMO SDRs for RF experimentation, direction finding, or digital communications, or they can be combined into larger phased-array structures.

Multiple tiles can be assembled into phased arrays using a modular lattice frame. The “Mini” starter array consists of 18 tiles, totaling 72 antennas. It is expected to provide roughly 34 dBi of gain, about 52.6 dBW of EIRP, and up to 60 degrees of electronic beam steering. While the Mini configuration is not large enough for moonbounce, it is intended for learning, experimentation, satellite downlinks, and long-range directional links.

For full EME capability, Open.Space proposes the “Moon” array, built from 60 tiles and 240 antennas in a one-meter-wide aperture. This configuration is expected to deliver around 39.3 dBi of gain and 63.1 dBW of EIRP, making moonbounce experiments feasible. Additional planned applications include radio astronomy, RF imaging, and advanced phased-array research.

One of the most notable aspects of the project is its proposed cost in U.S. dollars. Individual tiles are expected to sell for approximately $49 to $99 USD. The Mini array is projected at $899 to $1,499 USD, and the Moon array at $2,499 to $4,999 USD—significantly less than traditional EME hardware setups. The Open.Space hardware has not yet been released, but the project website lists March 2026 as the expected shipping date. The developers note that the system is not intended for radar applications due to export-control restrictions. Those interested can sign up on the Open.Space website to receive email updates when the hardware becomes available.

Many times, a school makes a last-minute decision to do a Livestream or runs into a last-minute glitch requiring a change of the URL, but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.

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 remains configured in the Columbus Module (145.990 MHz up {PL 67} & 437.800 MHz down). If a crewmember decides to pick up the microphone and turn up the volume, you may hear them on the air—so keep listening, as you never know when activity might occur.

The service module IORS is not currently in APRS configuration and is being used only for voice contacts at this time. HamTV in the Columbus Module is configured for scheduled digital amateur television operations on 2395.00 MHz.

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.

ESA-Led CCSDS Competition Registration Now Open

David Johnson, G4DPZ, AMSAT-UK Honorable Secretary reminds everyone that the ESA-led Competition, in collaboration with AMSAT-UK, AMSAT-DL, CCSDS, and Goonhilly Earth Station, is now open to European and Canadian teams and individual participants.

Entrants will work on real space communication standards, including CCSDS and LunaNet protocols. The European Space Agency (ESA) is launching a pilot program on behalf of the Consultative Committee for Space Data Systems (CCSDS). This outreach initiative aims to strengthen engagement with the European amateur satellite and academic communities.

Participants may choose to develop implementations for either of these CCSDS protocols:

LunaNet Signal-In-Space (LSIS-AFS)
Defines how lunar orbiters or surface systems broadcast a unified navigation and timing signal to support future missions on and around the Moon. Develop a functional concept or prototype demonstrating signal design, transmission, interpretation, or application for lunar missions.

Space Communications Session Control (CCSDS 235.1)
Defines how space missions establish, manage, and conclude communication sessions between spacecraft and ground systems. Create a practical, interoperable reference implementation aligned with the CCSDS 235.1 standard.

Winners will receive an invitation to attend a CCSDS conference, where they will present their results to the international CCSDS community.

An in-person workshop at Goonhilly Earth Station will be available to interested participants, providing a unique environment for collaboration, expert guidance, and accelerated development.

Help Wanted: Feature Story Editors & Video Editor

Sharing news of AMSAT activities, especially the work of the AMSAT Engineering Department, is an important function that supports AMSAT’s information and education mission. It is also an important tool for retaining current members, recruiting new members and for fund raising.

Frank Karnauskas, N1UW, AMSAT VP-Development is asking, “Do we have two volunteers who can step up and spend just a few hours a week to help keep our information channel flowing?

“For the Feature Story Editors, we have a pool of information that we’ve collected from Hamvention and Symposium presentations that can be quickly converted into short stories for publication in the ANS Weekly Bulletins and into feature stories for The AMSAT Journal. We typically start with a video or at least an audio recording of the presentation which you would convert into a written transcript using an application that we provide. The editor then uses the transcript and the author’s original PowerPoint slides to create the final articles.

“We also have the need for someone to write press releases for other AMSAT activities such as Educational Resources, the Youth Initiative, annual reports and so on.

“For the Video Editor, again we have a collection of videos from presentations that simply need opening titles to be added and a bit of “tuning up” inside the presentations themselves. There is no need for expensive software or especially super high power computers. Free software that is remarkably powerful but easy-to-learn is available. If a person is interested we would also welcome someone to create promotional video shorts or other programs they are willing to create.

“We’re not asking anyone for a life-long commitment to these positions. Anyone who is willing to say, ‘Hey, I can do five or ten stories’ would be a hero in my book.”

Persons interested in learning more about how they can make an important contribution can contact Frank at volunteer [at] amsat [dot] org.

Using Neural Networks to Recover Satellite Signals

Edwin Temporal has shown how his proprietary neuromorphic engine, GhostHunter (Anti-LIF), is being used to recover satellite data buried in the noise floor, which typical DSP methods would fail to do.

To recover the signals, Edwin uses trained Spiking Neural Networks (SNN). SNNs are artificial neural networks that draw further inspiration from nature by incorporating the ‘spiking’ on/off behavior of real neurons. Edwin writes:

“My engine has successfully extracted and decoded structured data from high-complexity targets by mimicking biological signal processing:

• Technosat: Successful decoding of GFSK modulations under extreme frequency drift and low SNR conditions.
• MIT RF-Challenge: Advanced recovery of QPSK signals where traditional digital signal processing (DSP) often fails to maintain synchronization. “These missions are fully documented in the https://temporaledwin58-creator.github.io/ghosthunter-database/, which serves as a public ledger for my signal recovery operations. Furthermore, the underlying Anti-LIF architecture is academically backed by my publication on TechRxiv, proving its efficiency in processing signals buried deep within the noise floor.”

In the database, Edwin shows how his Anti-LIF system has recovered CW Morse code telemetry and QPSK data from noisy satellite signals.

While Edwin’s Anti-LIF is proprietary, he is offering proof of concept decoding. If someone has a 250MB or less IQ/SigMF/Wav recording of a signal that is buried in the noise floor, they can submit it to him via his website, and he will run Anti-LIF on it for analysis.

Advanced readers interested in AI/neural network techniques for signal recovery can also check out his white paper on TechRxiv, https://tinyurl.com/ANS-025-Neural-Networks where he shows signal recovery from signals buried in WiFi noise, as well as results from use in ECG and Healthcare applications.

Satellite Shorts From All Over

• A key antenna in NASA’s Deep Space Network (DSN), one that was damaged last fall, is expected to remain offline until May. Then, it will be taken out of service again later this year for major upgrades. The DSS-14 antenna, a 70-meter dish at the DSN complex in Goldstone, California, was damaged Sept. 16 when it over-rotated, stressing cabling and piping. DSS-14 is one of three 70-meter antennas in the DSN; the others are located near Madrid, Spain, and Canberra, Australia. The 70-meter antennas are used to communicate with distant spacecraft or those experiencing technical problems. (ANS thanks SpaceNews for the above information.)
  
• China suffered a pair of launch failures within 12 hours on Jan. 16 and 17. This included the loss of a classified Shijian satellite after a Long March 3B lifted off at 1655 UTC from Xichang Satellite Launch Center in southwest China. The China Aerospace Science and Technology Corporation (CASC) confirmed the failure around 12 hours after liftoff, stating that the Shijian-32 satellite had been lost following a third stage anomaly. Roughly 12 hours later, the Ceres-2 lifted off at 0408 UTC on Jan. 17. from the Jiuquan Satellite Launch Center in northwest China. Galactic Energy confirmed the loss of the debut flight, stating that an anomaly had occurred and that the specific cause is under further investigation.

PSLV-C62 Mission Experiences Anomaly

The Polar Satellite Launch Vehicle (PSLV)-C62 mission carrying the ‘Anvesha’/EOS-N1 satellite and 15 co-passenger satellites launched by India on Monday encountered an anomaly during the end of the PS3 burn stage with ISRO chairman V Naryanan stating that “a deviation in the vehicle’s flight path” was observed.

“A detailed analysis has been initiated,” the Indian Space Research Organisation (ISRO) posted on X.

ISRO Chairman V Narayanan said a disturbance was observed in the vehicle at the end of the third stage, which was otherwise proceeding as expected.

“Today, we have attempted the PSLV C62 / EOS – N1 Mission. The PSLV vehicle is a four-stage vehicle with two solid stages and two liquid stages. The vehicle’s performance near the end of the third stage was as expected. (However), near the end of the third stage, we are seeing increased disturbance in the vehicle. Subsequently, a deviation in the vehicle’s flight path is observed. We are analysing the data and will come back at the earliest,” Narayanan said.

This is ISRO’s first major launch of 2026. The mission aimed to place an Earth observation satellite into orbit from the First Launch Pad (FLP) at Sriharikota.

The mission was carried out by NewSpace India Limited and represents the ninth dedicated commercial mission to build and launch an Earth Observation satellite.

For the first time, a single Indian private company, Dhruva Space, based in Hyderabad, contributed seven satellites to the mission. Chaitanya Dora Surapureddy, CFO and Co-founder of Dhruva Space, said they also launched four satellites that they built.

“We launched four satellites that we have built, three for customers and one for us, and we also help other companies with part of the integration of the satellite onto the rocket. Essentially, a total of nine of our systems, which we have built, are going onto the rocket. So, quite exciting that that’s a good number,” he said.

Surapureddy said their satellites are for low-data-rate communication, which can be utilised by amateur radio operators.

“The satellites that we launched are all for low data rate communication. Amateur radio operators can utilise it towards that, and also a good demonstration for these satellites, and also for low data rate communication that can be done,” he added

Message to U.S. Educators: ARISS Contact Opportunity Call for Proposals

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2026 and December 31, 2026. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

The deadline to submit a proposal is February 27, 2026.  Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An informational webinar session will be held on February 5, 2026 at 8 PM ET.

The Zoom link to sign up is: https://us06web.zoom.us/meeting/register/hijg24mPRK69uGC0gUq8zw

The Opportunity

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact.

Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

Please direct any questions to education@ariss-usa.org

Satellite Shorts from All Over

+ As of this writing, 4 complete AMSAT CubeSatSim Kits are still available for purchase from the AMSAT store. This kit allows you to build a CubeSat Simulator with no soldering, just assembly. CubeSatSim is a low-cost satellite emulator that runs on solar panels and batteries, transmits UHF radio telemetry, has a 3D printed frame, and can be extended by additional sensors and modules. It is perfect for the classroom or for public demonstrations. The kit can be purchased from the AMSAT store. Sorry, shipping is only available to U.S. addresses. (ANS thanks AMSAT Education for the above information)

+ AMSAT-EA’s latest PocketQube, HADES-SA (aka SpinnyOne) has been coordinated by the IARU. A 1.5 PocketQube. HADES-SA / SpinnyONE is a satellite operated by AMSAT-EA members to promote the use of CODEC2 voice and SSDV in satellite communications, both of which are open protocols. As secondary objectives, the satellite is also intended to test its Doppler-resistant modem and a new antenna deployment mechanism. The satellite includes a BBS that allows amateurs to send text messages and, optionally, upload CODEC2 recordings for transmission by the satellite. A sample CODEC2 transmission has been pre-recorded in Flash memory until new transmissions from Earth arrive. HADES-SA / SpinnyONE includes a digital camera provided (along with its dedicated software) by the UK-based company Spinning Around. The camera will capture images of the deployment mechanism —which contains a small commemorative plaque— as well as whatever lies within its field of view at that moment. Every three days, a new picture will be taken and transmitted to the ground using the SSDV protocol. Image transmissions will occur continuously every few minutes so that stations worldwide can receive the frames. In the event of a camera failure, an internally stored image will be transmitted instead. Tools and detailed instructions on how to use them will be published on the AMSAT-EA website at https://www.amsat-ea.org/proyectos. The satellite is scheduled to launch on the SpaceX Transporter-16 mission approximately March 14, 2026. (ANS thanks AMSAT-EA and the IARU for the information)

NASA Ends Crew 11 Mission Due To ‘Medical Concern’ With An Astronaut

NASA is bringing some of the crew aboard the International Space Station (ISS) back to Earth early due to medical concerns with one the astronauts.

NASA officials announced on Wednesday, January 7, that they had decided to cancel an upcoming spacewalk due to a medical issue with an undisclosed crew member. Hours later, the agency indicated that it wasn’t ruling out an early end to Crew-11’s mission, and confirmed that the unnamed crew member was in a stable, non-emergency condition. NASA officials finalized the decision to bring the astronauts home in an announcement on Thursday, January 8.

Mike Fincke, KE5AIT, and Zena Cardman, KJ5CMN, had been scheduled to step outside the International Space Station (ISS) on Thursday at about 13:00 UTC, kicking off a roughly 6.5-hour extravehicular activity (EVA). But that spacewalk was postponed.

A follow-up statement from NASA said, “Safely conducting our missions is our highest priority, and we are actively evaluating all options, including the possibility of an earlier end to Crew-11’s mission.” That crew includes both Cardman and Fincke, as well as Japanese astronaut Kimiya Yui, KG5BPH, and Russian cosmonaut Oleg Platonov. The crew was launched on August 1, 2025 and was not scheduled for return until mid-February, following the arrival of Crew-12.

The early return of Crew-11 shouldn’t cause any delays in the preparations to rollout and launch the agency’s Space Launch System (SLS) rocket for Artemis 2 — the first crewed mission to the moon in over 50 years — NASA Administrator Jared Isaacman said on Thursday, January 8. Artemis 2 is slated to roll to the launchpad for a liftoff no earlier than February 5.

NASA Marks 50 Years Of GOES Satellites

NOAA’s Geostationary Operational Environmental Satellites, or GOES programme started a revolution in meteorology and weather forecasting. With GOES-1, satellite-sourced weather data could be sourced without waiting for the satellite to pass overhead. Previous satellites could only provide data at the times they were passing overhead.

The first three GOES satellites carried an instrument called Visible and Infrared Spin-Scan Radiometer (VISSR). This instrument enabled meteorologists to collect a wider range of data as well as a fuller set of data than ever before. GOES-1 went up in 1974, with the next two arriving in the next five years

The second generation of GOES satellites added important weather observation instruments. With these, our understanding of phenomena such as El Niño and tropical storms improved greatly. Furthermore, beginning with GOES-7, an RF receiver was added as part of the Search and Rescue Satellite-Aided Tracking (SARSAT) system.

Timeline of GOES launches including key technological developments associated with each “generation” of satellites. (Figure credit: NOAA/NASA)

From 1994-2001, the third generation GOES satellites reached orbit. Innovations included the ability to narrow the area under observation to better understand local weather events. GOES-12 also included the Solar X-ray Imager (SXI) instrument, which added full-disk X-ray observations of the Sun to the toolkit of space weather watchers.

Gen 4 satellites, called GOES-N, ushered in improvements to positioning with star-tracker instruments. With these, the location of weather events could be more precisely determined. The Extreme Ultraviolet Sensor added to space weather observations. Scan rates were quickened to one-minute scans, which aided in understanding severe weather outbreaks and issuing warnings.

The current generation of GOES satellites, known as GOES-R, added a variety of capabilities. These satellites feature the ability to narrow in and zoom out from local to global views with a choice of scan rates. Fire-detection instruments were added for the first time ever on a geostationary satellite. Many hobbyists enjoy receiving direct L-band downlinks from these satellites.

Two U.S. Schools/Organizations Moved Forward in ARISS Selection Process

Amateur Radio on the International Space Station (ARISS) is pleased to announce the U.S. schools/host organizations newly selected for 2026 ARISS contacts. A total of two 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.

The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the two U.S. host organizations during the July – December 2026 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 school and host organization are:

• YOTA Summer Camp in Huntsville, AL seeking a contact date between June 14 – 19, 2026.
• University Heights School of Medical Arts in Jonesboro, AR seeking a contact date between July and December 2026.

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN) and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio. For more information, see http://www.ariss.org.

Satellite Shorts from All Over

+ LACHIT-1 (Live Amateur Communication Hub for Innovative Technologies – One), the first satellite developed Assam Don Bosco University (ADBU) in Northeast India, is scheduled for launch aboard Indian Space Research Organisation’s (ISRO) PSLV-C62 rocket on January 12. The LACHIT-1 mission is a student-led initiative involving more than 50 students and faculty members drawn from across the Northeast, including Assam, Meghalaya, Nagaland, Arunachal Pradesh and Manipur states. The satellite will carry a UHF downlink using 2-FSK modulation at up to 9k6 kb with store and forward capability and a CW beacon. Frequencies for a telemetry and data downlink on 436.175 MHz and for the beacon on 435.360 MHz have been coordinated by the International Amateur Radio Union (IARU). (ANS thanks Northeast News and IARU for the above information.)

+ A live Satellite Communication Demonstration with the International Space Station (ISS) was successfully conducted in Pransla village, Gujarat (India) on 29 December 2025 with more than 12,000 students assembled. The live science and space outreach program was conducted with the active support of AMSAT-INDIA and Upagraha Amateur Radio Club (UpARC) at Indian Space Research Organisation’s U R Rao Satellite Centre. Basic concepts like ham radio, satellite communication, uplink & downlink, azimuth, elevation, frequencies, etc., and satellite tracking were explained so students could understand the upcoming live ISS pass. Three confirmed two-way contacts were made during the single ISS pass before what may be one of the largest crowds ever assembled for a satellite demonstration. (ANS thanks Rajesh Vagadia, VU2EXP, Regional Coordinator – AMSAT-INDIA, for the above information.)

+ 2025 was a banner year for shattering launch records worldwide. The 324 orbital launch attempts in 2025 represented a 25% increase from 2024’s previous record of 259. Almost 60% of all launch attempts came from the U.S., with SpaceX conducting 170 of the 193 American launches. China was second with 92 launches during the year. (ANS thanks SpaceNews for the above information.)

+ SpaceX is lowering orbits of 4,400 Starlink satellites to 480km throughout 2026, reducing ballistic decay time by 80% and preventing orbital debris accumulation risks. Lower altitude decreases collision risk in increasingly crowded low Earth orbit. Deorbiting faster prevents long-term orbital contamination. Massive orbital reconfiguration represents proactive response to congestion challenges. Nearly half of Starlink’s 9,400 operational satellites will require altitude adjustment. The current 550-kilometer orbit sits within crowded debris-prone region. The proposed 480-kilometer altitude places satellites in a less congested orbital band. (ANS thanks NASA Space News for the above information. Read the full story at https://nasaspacenews.com/2026/01/spacex-lowering-orbits/.)

+ AMSAT-UK are pleased to announce they will be holding a webinar to advise European amateurs regarding the ESA / CCSDS sponsored outreach competition to develop reference protocols at 16:00 UTC on Wednesday 14th January. The webinar will be via Zoom and the event will be recorded. NOTE: this competition is for European and UK hams only. For information and registration see https://amsat-uk.org/2026/01/06/webinar-for-ccsds-competition/.

Soyuz Rideshare Launch Deploys Several New Amateur Radio Satellites in Orbit

A Soyuz-2.1b launch vehicle with a Fregat upper stage launched successfully on December 28 at 13:18 UTC (8:18 a.m. EST), deploying a total of 52 satellites into orbit. The mission was operated by Roscosmos and lifted off from the Vostochny Cosmodrome in eastern Siberia. The primary payloads were two Aist-2T Earth-observation satellites.

Among the secondary payloads were at least eight satellites using amateur radio frequencies, including several that received coordination through the International Amateur Radio Union. Initial on-orbit checkout and commissioning activities are underway, with beacon reports and operational activity continuing to be reported.

QMR-KWT-2 (Moon of Kuwait) is a 1U CubeSat carrying an amateur radio mission led by Oleg Razin, R3AOR, in cooperation with the Moscow Technical University of Communication and Informatics. The satellite features an FM amateur radio transponder intended to encourage participation by students and new operators, along with a miniature camera capable of transmitting SSTV images. The mission operates under IARU coordination, with a downlink on 436.950 MHz and a transponder uplink on 145.920 MHz.

Lobachevsky (RS83S) is a 16U CubeSat developed by the National Research State University of Nizhny Novgorod as part of Russia’s Space-π educational program. The spacecraft carries an amateur radio digital repeater supporting message exchange between radio amateurs worldwide, along with imaging payloads transmitting SSDV and SSTV pictures. IARU-coordinated frequencies include a repeater uplink on 435.500 MHz, repeater downlink on 145.910 MHz, a telemetry and image downlink on 436.320 MHz, and an experimental X-band downlink on 10.470 GHz.

SAKHACUBE-CHOLBON (RS-18S) is a 1U CubeSat developed by the Sakha Science Academy as the first satellite of the Republic of Sakha (Yakutia). The spacecraft uses a single UHF amateur radio transceiver for telemetry, command, and educational payload data, including digital transmissions and SSTV images. The satellite operates with IARU coordination, including a downlink on 437.350 MHz.

Several additional satellites on the mission are reported to use amateur radio frequencies without IARU coordination, including Polytech Universe-6, Scorpion, Luca-1, and Galapagos-UTE. In addition to the amateur-frequency spacecraft, the mission also deployed three Iranian Earth-observation satellites — Paya, Zafar-2, and Kowsar — intended for monitoring agriculture, mapping natural resources, and studying environmental conditions.

HDMI Converter Installed on ISS HamTV System, Expanding Video Capabilities

Amateur Television operations aboard the International Space Station received a significant upgrade on December 22, when an HDMI converter was installed on the ARISS HamTV system. The new hardware expands video capabilities for HamTV and supports the use of a broader range of onboard cameras during future educational contacts. The installation was performed during scheduled maintenance activities by NASA astronaut Chris Williams, KJ5GEW. ARISS reported that the HDMI converter can generate a video test signal when the system is in standby mode, providing a clear visual indication of system readiness and video-path functionality.

The December upgrade builds on HamTV’s return to operation earlier in the year. The HamTV unit was installed aboard the ISS on July 29 by astronaut Jonny Kim, KJ5HKP, after several years offline for repairs. Following installation, ARISS confirmed acquisition of signal reports from amateur stations as the system began transmitting a carrier on 2395 MHz, with continued testing through August confirming stable carrier operation.

Those efforts led to successful video use during an educational contact on October 18 with scouts in the United Kingdom. During that event, Jonny Kim, KJ5HKP, answered student questions while appearing live on station via HamTV. Pre-contact testing included tone and color-bar transmissions, followed by a successful live video downlink from the ISS.

In the days following the December 22 maintenance activity, amateur observers again reported reception of color-bar test signals, confirming proper operation of the updated video chain. On December 23, amateur operator Scott Chapman, K4KDR, reported successful reception of HamTV test video during an ISS pass over North America, documenting decoding of a video test pattern using a one-meter S-band dish.

HamTV uses DVB-S digital amateur television transmitted on 2395 MHz, and reception typically requires a 2.4-GHz-capable antenna, a low-noise amplifier, and a compatible DVB-S receiver or software-defined radio. With the HDMI converter installed and testing completed, ARISS has indicated that further HamTV activity is expected during educational contacts in 2026.

For those interested in receiving HamTV, Scott Chapman, K4KDR, has published a community guide describing one method of decoding and recording HamTV test video using SatDump and VLC Media Player: https://www.qsl.net/k/k4kdr/how-to/HamTV_SatDump_VLC.pdf. Additional technical background, reception reports, and ground-station information are maintained by the British Amateur Television Club (BATC): https://wiki.batc.org.uk/HAMTV_from_the_ISS.

Changes to AMSAT TLE Distribution for January 2, 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/.

This week there are no additions or deletions to the AMSAT TLE distribution.

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.

Scheduled Contacts

+ Recently Completed

No International Space Station school contacts were completed during this reporting period, as many schools were closed for the holiday break.

+ Upcoming Contacts

No upcoming school contacts are currently scheduled; scheduling will resume once schools return from the holidays.

Many times a school may make a last-minute decision to do a Livestream or run into a last-minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication.  You can always check https://live.ariss.org/ to see if a school is Livestreaming.

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 remains configured in the Columbus Module (145.990 MHz up {PL 67} & 437.800 MHz down). If a crewmember decides to pick up the microphone and turn up the volume, you may hear them on the air—so keep listening, as you never know when activity might occur.

The service module IORS is not currently in APRS configuration and is being used only for voice contacts at this time. HamTV in the Columbus Module is configured for scheduled digital amateur television operations on 2395.00 MHz.

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

AMSAT Youth Initiative: “Satellites and Climate Change” Course Now Online

The beta release of “Satellites and Climate Change” is now available online. This course is the second online course published as part of the AMSAT Youth Initiative’s series “How Satellites in Space Help Us Live a Better Life Here on Earth.”

The course was written by Eric Sonnenwald, N2XSE. Eric, a retired science teacher in Lake Hopatcong, New Jersey, is a graduate of Montclair State University with an M.S. in Geosciences and the former Science Curriculum Coordinator for Hardyston Middle School. In order to expedite the development of the courses and keep costs low, one of Eric’s most challenging tasks in creating the lessons is sourcing copyright-free graphics and related resources. Fortunately there is a relatively abundant pool of free materials available on government and college websites from which to draw.

From Eric’s content, other AMSAT volunteers use specialized software to format the content into an online presentation.

The “Satellite and Climate Change” course follows the “Introduction to Satellite Meteorology” course introduced at Hamvention 2025. Several improvements have been added to the lesson format including the ability to zoom in and enlarge complex graphics shown in the screens. This is an important addition since students often use smartphones or tablets with much smaller screens that desktop or laptop computers

The third course, “Satellites and Pollution Control” is scheduled for launch within the next week or two, followed by “Satellites and Preservation of Natural Resources” in January. In all, fourteen courses are scheduled for publication by the end of 2026.

Frank Karnauskas, N1UW, AMSAT Vice President-Development and creator of the Youth Initiative explains, “Our approach to getting youth interested in satellites and amateur radio is to attract their attention and participation in topics of current events and widespread interest. We explain how satellites are an integral component of almost every facet of modern living and from there introduce the concept of critical information provided by satellites, then telemetry, and communications. We provide access to experiences with satellite telemetry via amateur radio satellite ground stations to access ARISS packet and voice stations aboard the International Space Station as well as other amateur radio satellites. Essentially, we try to ‘set the hook’ by giving students access to SWL experiences in the same way many of us got our start in amateur radio and with hands-on opportunity to download and analyze actual telemetry.

“A unique concept in designing the Youth Initiative program is that it is a community-based program available to all youth, through their own self-interest, though home-schooling and through programs such as Scouting, 4H or community based programs for youth with special needs. Teachers are welcome to incorporate the materials into their curriculum where their school boards allow them to do so. But, the key here is that school participation is not needed for parents or other leaders to utilize our materials.”

Karnauskas further explains that all materials are available online at no charge to every and all persons interested in furthering the interest of students in science, technology, engineering, art and mathematics.

AMSAT is grateful to Amateur Radio Digital Communications for a generous grant to cover the cost of software licenses for online development and for supplemental technical artwork.

Launch Teams Practiced Artemis 2 Countdown

In a prelude to the real deal, the four astronauts of the Artemis 2 mission boarded their Orion spacecraft inside the Vehicle Assembly Building at the Kennedy Space Center on Saturday afternoon, Dec. 20.

The three Americans and one Canadian participated in a launch day rehearsal referred to as the countdown demonstration test or CDDT. It was the first opportunity for everyone involved with the mission to be on hand and to go through the motions of the big day with the fully integrated rocket in the loop, instead of just data simulations. The test appeared to reach its conclusion with a cutoff of the simulated countdown at the T-29 seconds point at 5:51 p.m. EST (2251 UTC).

The rehearsal is already running at least a month behind schedule. It was scheduled for November 19 but NASA postponed that, eventually blaming “a blemish” on a thermal barrier surrounding the Orion crew access hatch which prevented its closure.

The test was rescheduled for Dec. 17, but that too was abruptly delayed without explanation.

The launch of Artemis 2 is currently slated for no earlier than February 6. NASA also says the launch will take place no later than April 2026.

Satellite Shorts From All Over

+ They weren’t home for Christmas, but astronauts in space found their own way to make the season bright. They’ve even hung their space stockings by the airlock with care. Four astronauts on the International Space Station (ISS) sent their best Christmas wishes to Earth as they orbit our planet. NASA astronauts Mike Fincke, Zena Cardman and Chris Williams and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) sent a video Christmas card home as they and three other crewmates spend the holidays 250 miles (400 kilometers) above Earth. “Greetings to planet Earth, all of our friends and family, from Expedition 74 aboard the International Space Station, flying high above,” said Fincke, who commands the Expedition 74 crew on the ISS. “Thinking of you during this holiday season.” Watch the heartwarming greeting and feel the season bright at https://tinyurl.com/ANS-362-Greetings . [ANS thanks space.com for the above information.]

+ The global space sector is entering a phase of large-scale satellite constellations and expanded human lunar activity, driving a sharp increase in demand for access to orbit. Within the next two decades, the total mass launched to space is expected to reach several hundred thousand tons, with annual launch counts projected in the tens of thousands and continuing to grow. Launch providers therefore face simultaneous requirements for low cost, high flight rates, and airline-style reliability in space transportation systems. Reusable launch vehicles have reduced per-flight cost, but they do not yet deliver the launch tempo and reliability needed for this next phase of activity. A study in the Chinese Journal of Aeronautics argues that artificial intelligence applied across launch vehicle life cycles could address these remaining bottlenecks and become a disruptive technology following reusability in space transportation.The authors outline four main roles for AI in launch systems: agile test and launch preparation, high-reliability flight, rapid maintenance, and efficient safety operation and control.

W2RS Memorial AMSAT CW Activity Day to be Held January 1, 2026

In March 2022, the AMSAT community lost one of our pioneers when Ray Soifer, W2RS, became a silent key. In addition to his numerous contributions to AMSAT and the worldwide amateur satellite community, Ray was also the long time organizer of AMSAT’s CW Activity Day – previously AMSAT Straight Key Night – held in conjunction with the ARRL’s event on New Year’s Day. In recognition of Ray’s long time service to AMSAT and his keen interest in CW operating via satellite, AMSAT’s CW Activity Day is now known as the W2RS Memorial AMSAT CW Activity Day.

The rules are simple – operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2026. Straight keys and bugs are encouraged, but not required. Logs are not required, but operators are encouraged to submit a report of their activity to the AMSAT-BB. Photos and video clips of activity are also encouraged – post them on X or other social media networks and tag @AMSAT or #amsat.

Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

New Satellite Tracking Application Released

Bob McGwier, N4HY, has announced the release of a new satellite tracking application entitled Visible Ephemeris.

Visible Ephemeris is a modern, spiritual successor to Quiktrak (1986), re-engineered for the Raspberry Pi 5 and modern silicon. It is capable of propagating 13,000+ satellites in real-time with sub-second updates while maintaining <5% CPU utilization.

Visible Ephemeris is high performance physics based program using Kelso/Villado SGP4, to track satellites (all in the Celestrak TLE). It uses McGwier’s implementation of Pedro Escobal AOS/LOS search but rewritten for altitude and not Eccentric Anomaly. The code is designed for and intended for Raspberry Pi and displays graphics components using Web UI.

It features a Hybrid Decoupled Architecture where the UI, Orbital Mechanics, and Network Services run on independent threads, ensuring the interface never freezes—even during heavy calculation loads.

Visible Ephemeris has been released under the MIT license and further details can be found at https://github.com/n4hy/VisibleEphemerisCPP.git

How University Space Clubs Prepare for Their First Satellite Project

The spark of curiosity and ambition often starts in a university lab: a handful of students gather, sketch rough diagrams on whiteboards, debate orbital mechanics at midnight, and dream of seeing their own hardware flying above Earth. For many of these aspiring engineers and scientists, involvement with a student satellite club represents more than just coursework: it’s their first real shot at participating in space exploration. These clubs, across universities worldwide, transform ideas into hardware and enthusiasm into the kind of rigorous planning it takes to actually launch.

From Idea to Kickoff: Forming the Team And Setting Goals

At the outset, a group of students (often from different disciplines like mechanical engineering, computer science, electronics, or physics) comes together with a shared interest in building a satellite. For many, this marks the beginning of a university satellite project rather than just a class exercise, and some teams even use a dedicated research assistant to streamline early planning and gather technical insights. The club defines its mission: maybe it’s Earth observation, environmental sensing, communications testing, or a technology demonstration.

The first practical step is to assemble a core team: subsystem leads for avionics, communications, structure, power, payload, and operations. This division, common in professional aerospace teams, helps students learn early how complex spacecraft are divided into interdependent systems. Some clubs also look for faculty advisors or collaborators from industry to guide them through unfamiliar territory.

Once the pieces are in place, the club sets goals and schedules. Will this be a CubeSat, a smaller PocketQube, or a microsatellite? What payload makes sense given the budget and skills available? How will ground station communications work? Early decisions help steer the entire project and establish realistic expectations about scope, cost, and timeline.

The Importance of Design, Simulation, And Prototyping

Design is where theory meets reality. Students work on 3D models of satellite structure, layout of solar panels, shielding, antennas, and internal boards. They simulate thermal, electrical, and mechanical stresses to ensure their satellite can survive launch vibrations and the harsh environment of space. Many clubs employ computer-aided design (CAD) tools and simulation software to anticipate potential issues.

Prototyping follows design. Groups build mock-ups or engineering models — sometimes out of inexpensive materials — to test fits, deployment mechanics, and subsystem integration. This hands-on phase reveals assembly challenges that might not show up on the screen. It also builds critical skills: soldering, wiring, 3D printing parts, basic clean-room assembly practices, and rigorous testing.

Building Support Networks: Mentors, Funding, Partnerships

A student group rarely operates in isolation. Universities might provide lab space, clean rooms, testing facilities, and occasionally small budgets, but often, additional external support is crucial. Clubs frequently reach out to faculty in engineering, physics, or computer science departments for mentorship. Some clubs also form partnerships with research institutions, local aerospace companies, amateur radio communities, or national space agencies to gain access to more advanced equipment.

Ground-Station Planning And Mission Operations Prep

One often-overlooked but essential component is the ground segment. A successful satellite needs to reliably communicate with Earth: upload commands, receive telemetry, downlink data. For many student teams, building or adapting a ground station is part of the learning curve.

On the operations side, the team writes procedures and schedules: when to turn on instruments, how to run health checks, how to handle contingencies like partial failures or unexpected behavior in orbit. This mission-operations mindset trains students in the discipline of space mission management.

Preparing for Launch: Testing, Regulatory Paperwork, And Final Review

As the launch nears, the club shifts into full production mode. All subsystems must be assembled, tested, and integrated. Thermal-vacuum tests, vibration tests, and electromagnetic interference tests help ensure the satellite will survive the rigors of launch and space. Students often run repeated functional tests: power cycling, communications tests, antenna deployment, battery charging, and simulating real in-orbit operations.

At the same time, they must deal with paperwork: launch licensing, radio-frequency licensing, compliance with local and international space regulations, and environmental reviews. Some universities facilitate this, but others require the student club to navigate the regulatory process itself, a valuable learning experience in project management.

Once everything checks out, the team must coordinate with a launch provider, reserve a ride-share slot or secure a deployment contract, define orbit parameters, and prepare payload manifests.

The First Launch, And What Comes Next

Reaching orbit is a major milestone, but for student-built satellites, it’s only the beginning. First missions are typically demonstration or technology-testing. Once the satellite is in orbit, the ground station begins routine operations: receiving telemetry, validating system health, operating payloads, and collecting data.

Why do these clubs matter? Beyond the immediate technical achievement, they cultivate a culture of innovation, hands-on learning, and collaboration. They lower the barrier to entry into space for students who might never have had the opportunity otherwise. Many graduates of student satellite clubs go on to careers in aerospace, research, or related industries, carrying with them practical skills in design, systems engineering, hardware testing, and project management.

As university clubs gain experience and build reputations, they do more than just offer small satellite development for students; they also help governments and space agencies recognize the value of small satellites: low-cost experimentation, rapid iteration, educational outreach, and workforce development.

Soyuz Crew Lands Ending Eight-Month Space Research Journey

The crew of Soyuz MS-27, including NASA astronaut Jonny Kim, KJ5HKP, along with Russian Cosmonauts Sergey Ryzhikov and Alexey Zubritsky, returned safely to Earth after living aboard the International Space Station (ISS) in weightlessness for 245 days. The return marked the end of ISS Expedition 73.

Lieutenant Commander (LCDR, U.S. Navy) Jonny Kim was born and raised in Los Angeles, California to Korean-American immigrants. He enlisted in the Navy as a Seaman recruit after graduating high school in 2002. After completion of Hospital Corpsman “A” school training, he reported to Basic Underwater Demolition/SEAL (BUD/S) training in Coronado, CA. After completing his training at Naval Special Warfare, Kim reported to the John F. Kennedy Special Warfare Center and School in Fort Liberty, NC for the Special Operations Combat Medic Course. He was assigned as a Special Warfare Operator to SEAL Team THREE in San Diego, CA and obtained various qualifications including Military Freefall Parachutist, Advanced SCUBA, Combatant Diver (closed circuit rebreather), Naval Special Warfare Special Reconnaissance Scout and Sniper, and Advanced Special Operations Techniques. As a Navy SEAL he completed more than 100 combat operations.

In 2012, Petty Officer First Class Kim was commissioned as a naval officer through the Navy’s enlisted-to-officer commissioning program, Seaman to Admiral-21, following graduation from the University of San Diego. Kim obtained his medical degree from Harvard Medical School and completed his internship with the Harvard Affiliated Emergency Medicine Residency at Massachusetts General Hospital and Brigham and Women’s Hospital in Boston, MA.

Kim is an Aeromedical Dual Designated (AMDD) Naval Aviator and Flight Surgeon, he completed his primary flight training at Naval Air Station (NAS) Corpus Christi, TX, helicopter advanced flight training at NAS Whiting Field in Milton, FL, and the Naval Flight Surgeon course at the Naval Aerospace Medical Institute at NAS Pensacola, FL.

Selected by NASA in 2017, Kim completed two years of training as an Astronaut Candidate. Training included technical and operational instruction in International Space Station systems, Extravehicular Activities (EVA) Operations, T-38 flight training, robotics, physiological training, expeditionary training, field geology, water and wilderness survival training, and Russian language proficiency training. In 2020, Kim began his support of International Space Station operations as a Capsule Communicator (CapCom) in Mission Control Center Houston and the Artemis program under the astronaut Exploration branch. He served as the International Space Station’s Increment Lead for Expedition 65 in 2021.

As part of his astronaut training, Kim earned his Technician Class amateur radio license in July of 2024.

Kim launched to the International Space Station on April 8, 2025, as a flight engineer on the Soyuz MS-27 spacecraft. He spent eight months aboard the station as an Expedition 72/73 flight engineer, conducting science experiments and maintaining the space station. During the science expedition, Kim orbited the Earth 3,920 times and traveling nearly 104 million miles. He saw the arrival of nine visiting spacecraft and the departure of six during his time in orbit.

This was Kim’s first spaceflight, where he served as flight engineer for Expedition 72 and 73. This also was Zubritsky’s first trip to the space station. Ryzhikov now has logged a total of 603 days in space during three trips to the orbital complex, ranking him 13th all time.

The three crew members were flown by helicopter to Karaganda, Kazakhstan, where recovery teams are based. After medical exams, Kim boarded a NASA aircraft and returned to Houston to spend Christmas with his wife and their three children.

Expedition 74 is now underway with veteran NASA astronaut Mike Fincke, KE5AIT, as commander leading six flight engineers including NASA astronauts Zena Cardman, KJ5CMN, and Chris Williams, KJ5GEW, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, KG5BPH, and Roscosmos cosmonauts Oleg Platonov, Sergey Kud-Sverchkov and Sergei Mikaev.

CCSDS Development Competition Open to European Hams

The European Space Agency (ESA) is presenting a pilot programme on behalf of The Consultative Committee for Space Data Systems (CCSDS) and is pleased to announce a new outreach initiative aimed at strengthening engagement with the European amateur satellite and academic communities. This initiative supports the wider objective of promoting the adoption and practical application of CCSDS space communication standards.

CCSDS invites European amateur satellite operators, students, educators, and academic researchers to participate and to help advance open, interoperable space communication technologies.

ESA, in partnership with Goonhilly Earth Station, CCSDS, AMSAT-UK, and AMSAT-DL, are launching a competition to develop high-quality reference implementations of selected CCSDS protocols.

This competition is sponsored by the European Space Agency (ESA).

About the Competition

This programme invites participants to:

Develop open, standards-compliant reference implementations of CCSDS protocols
Contribute to a shared technical resource for amateur satellite operators, universities, and research groups
Gain recognition within both the CCSDS community and the broader space communications field

An in-person hackathon at Goonhilly Earth Station will be available to interested participants, providing a unique environment for collaboration, expert guidance, and accelerated development.

Goonhilly Earth Station is coordinating the competition and will not assert any ownership over Hackathon/Competition outputs.

Prize

Winners of the competition will receive an invitation to attend a CCSDS conference in the United States, where they will present their results to the international CCSDS community.

Protocols Featured in the Competition

These are the outlines of the two CCSDS protocols selected for this competition:

LunaNet Signal-In-Space Recommended Standard – Augmented Forward Signal (LSIS – AFS)
The LSIS–AFS standard defines how lunar orbiters or surface systems broadcast a unified navigation and timing signal to support future missions on and around the Moon. It provides a framework for creating an enhanced, interoperable “forward signal” that spacecraft, rovers, and astronauts can use for more accurate positioning, timing, and situational awareness.

Space Communications Session Control (CCSDS 235.1)

The CCSDS 235.1 standard defines how space missions establish, manage, and conclude communication sessions between spacecraft and ground systems. It provides a common framework that ensures reliable coordination when exchanging data, sending commands, and transitioning between communication states.

Participants may choose either to develop a functional concept or prototype that demonstrates how the LSIS–AFS signal could be designed, transmitted, interpreted, or applied to support future lunar missions, or to create a practical, interoperable reference implementation of Space Communications Session Control aligned with the CCSDS 235.1 standard.

A Long-Term Vision: Toward a Cislunar Amateur Radio Payload

CCSDS is pleased to highlight a longer-term aspiration linked to this initiative. In close cooperation with its partners—particularly ESA, which is proposing a future cislunar amateur radio payload—CCSDS intends to support the preparation of the most successful protocol implementations for potential consideration for flight.

This offers an exceptional opportunity for community-developed CCSDS-compliant software to be demonstrated in a deep-space operational environment.

This prospective mission is subject to funding and programme approval.

Contact and Expressions of Interest

For enquiries or to express interest in participating, please contact: esa-competition@amsat-uk.org

Additional details—including eligibility criteria, protocol specifications, submission requirements, evaluation processes, and timelines—will be released soon.

A Dying Satellite May Photograph Asteroid Apophis in 2029

An Australian company wants to join efforts to study a rare space event, conducting its own flyby of the asteroid Apophis when it makes its close approach to Earth in 2029.

Sydney-based HEO Robotics, a provider of commercial satellite-to-satellite imagery, wants to add to the international missions already planning to get up close to the 1,115-foot-wide (340 meters) asteroid Apophis as it zooms by Earth in April 2029 by buying a satellite near the end of its life up in geostationary orbit and use its remaining fuel.

Satellites in the geostationary belt (GEO) orbit 22,236 miles (35,786 kilometers) above the equator. Spacecraft nearing the end of their lives use their remaining fuel to head into a so-called graveyard orbit above GEO to take themselves out of the way of the operational satellites. HEO aims to buy a satellite near the end of its mission lifetime and, using a little more fuel than needed for the graveyard trip, make a close approach to Apophis, which will pass within the GEO belt when it makes its close approach to Earth on Friday, April 13, 2029.

Boeing’s Next Starliner Flight Will Carry Cargo Only

NASA ended months of speculation about the next flight of Boeing’s Starliner spacecraft, confirming that the vehicle will carry only cargo to the International Space Station.

NASA and Boeing are now targeting no earlier than April 2026 to fly the uncrewed Starliner-1 mission, the space agency said. Launching by next April will require completion of rigorous test, certification, and mission readiness activities, NASA added in a statement.

Starliner’s first flight in December 2019, without crew, had to be truncated after software problems plagued the vehicle. It was nearly lost shortly after launch as well as before atmospheric reentry. It did not make a planned rendezvous with the space station.

The second mission, Orbital Flight Test 2, took place in May 2022. Because of problems on the previous mission, this spacecraft also flew uncrewed. This flight was more successful, reaching the space station despite some thruster issues.

NASA then spent more than two years testing Starliner on the ground before its first crewed flight in 2024, carrying NASA astronauts Butch Wilmore and Suni Williams, KD5PLB. During its approach to the space station, the Starliner spacecraft once again experienced serious thruster issues. (However, the life-and-death nature of this flight was not revealed until nearly a year later.) Starliner ultimately docked with the station, but after heated deliberations, NASA informed Boeing that the vehicle would return to Earth uncrewed.

As a result, a Dragon mission was launched later in 2024 carrying just two astronauts instead of a full complement of four. This allowed for the safe return of Wilmore and Williams in March 2025.

Satellite Shorts from All Over

+ Earth observation satellite TUBIN of Technical University Berlin, Germany is about to re-enter Earth’s atmosphere in the upcoming days; 16th December +/-1 day. During the orbit decay it is transmitting a telemetry beacon every 10 seconds, including position, attitude, temperatures, etc. via amateur radio UHF band at 435.950 MHz. Researchers would appreciate support of additional radio amateurs listening in and forward the received telemetry data. Further information can be found at https://community.libre.space/t/tubin-tubsat-27-re-entry/13998. As the orbit is decaying quite fast, most recent TLE’s shall be used, which are frequently updated at https://db.satnogs.org/api/tle/?format=3le&norad_cat_id=48900. Any decoded frames, audio recordings or reception reports are very welcome and can be submitted following the instructions in https://community.libre.space/t/tubin-tubsat-27-re-entry/13998. The team at TU Berlin will collect all contributions and can provide specialized TUBIN re-entry QSL cards.

+ At next year’s World Radiocommunications Conference (WRC-25), governments will face a choice that goes to the heart of how we monitor our warming planet. Some regulators are wondering whether to open part of the X-band — the 8.025–8.4 GHz range used by Earth observation satellites — to 5G and 6G mobile networks. Several major telecom operators have been pushing for this move, arguing that they could use this spectrum more efficiently and pay countries handsomely for the right to do so. Eleven satellite-focused companies have formed the Remote Sensing Collective to resist the change. They’ve done this because the satellites we depend on to understand the environment depend in turn on the X-band. (ANS thanks SpaceNews for the above information.

KSLV-II Mission Deploys 13 Satellites, Including New Amateur Radio Payloads

South Korea recorded another significant achievement in its growing domestic space program with the successful nighttime launch of the Korea Space Launch Vehicle-II (KSLV-II), also known as Nuri, from the Naro Space Center in Goheung, South Korea. Liftoff occurred at 16:13 UTC on 26 November 2025 after a brief delay caused by an abnormal pressure-sensor signal in the rocket’s umbilical system. After the anomaly was resolved, Nuri ascended smoothly and became South Korea’s first orbital launch conducted during nighttime operations.

The vehicle performed nominally throughout ascent, completing stage separations on schedule and surpassing the 500 km mark roughly seven minutes after liftoff. Orbit insertion occurred approximately twelve minutes into the flight, followed one minute later by the deployment of CAS500-3, a 500-kilogram scientific satellite designed for highly light-sensitive Earth-observation missions. Korea Aerospace Administration (KASA) officials confirmed multiple ground-station contacts with CAS500-3 during its first day on orbit, including passes over the King Sejong Station in Antarctica.

Following the primary payload, Nuri deployed twelve CubeSats, nine of which operate in the amateur UHF bands. Of these, three satellites were fully IARU-coordinated. The twin SNUGLITE-III CubeSats—HANA (436.460 MHz) and DURI (436.788 MHz)—developed by Seoul National University, each carry a 9600-bps GMSK AX.25 digipeater, UHF beacons, and an S-band imaging payload at 2405.000 MHz. These spacecraft support amateur-radio training, GPS-RO technology demonstrations, and formation-flying experiments. The third coordinated payload, SPIRONE (436.650 MHz / 2425.100 MHz) from Sejong University, combines an environmental mission to detect marine plastic with a GMSK beacon and an S-band transponder intended for amateur-radio experimentation.

Six additional CubeSats on the mission also used amateur-band downlinks but were not coordinated through the IARU. These include JACK-003, JACK-004 (both 436.300 MHz), BEE-1000 (436.500 MHz), PERSAT01 (437.125 MHz), K-HERO (437.165 MHz), and INHA-RoSAT (437.665 MHz). While uncoordinated, they remain of interest to amateur-radio satellite observers, particularly during early beacon activity and commissioning efforts as teams work to establish first contact.

This launch also reflects South Korea’s broader strategy of strengthening its commercial aerospace ecosystem. For the first time, primary launch-operation responsibility was handled by Hanwha Aerospace, marking a transition toward greater private-sector involvement in national space access. Despite a two-and-a-half-year gap since the previous Nuri flight, Hanwha and its partners maintained launch readiness and executed the mission successfully—an encouraging sign for Korea’s long-term space-industry development.

KASA plans at least two additional Nuri launches through 2027, with the goal of supporting annual flights thereafter and ultimately developing a next-generation booster capable of heavier payloads and deep-space missions. For the amateur-satellite community worldwide, the KSLV-II program’s demonstrated ability to deploy large numbers of small spacecraft—including coordinated amateur payloads—is a promising development, expanding future rideshare opportunities and adding new signals to monitor across UHF and S-band.

ISS Deployment Added Five New Education-Focused Amateur Radio Missions

Seven satellites were deployed from the International Space Station on December 2, 2025, with release times spanning 08:10 UTC to 09:50 UTC in three batches using the Voyager Space NanoRacks CubeSat Deployer (NRCSD) system. Five of the deployed spacecraft—SilverSat, RHOK-SAT, Content-Cube, EagleSat-2, and Foras Promineo—operate on amateur radio frequencies and represent a broad collection of university, student-led, and educational missions. SatNOGS stations scheduled more than 700 observations during the first 24 hours as the satellites drifted away from the ISS to form their initial orbits, requiring careful Doppler evaluation and coordinated tracking during the early identification phase.

The first release at 08:10 UTC deployed the 6U DUPLEX satellite, which does not carry an amateur-radio payload. A second deployment window at 08:20 UTC released four 1U spacecraft: SilverSat, RHOK-SAT, Content-Cube, and CU-Alpha. Of these, CU-Alpha operates outside the amateur bands using LoRa at 915 MHz. The final release at 09:50 UTC deployed the two 3U amateur missions, EagleSat-2 and Foras Promineo, completing the NRCSD-29 sequence.

SilverSat, a 1U open-source CubeSat designed to inspire student interest in space science and engineering, was the first amateur satellite from NRCSD-29 to be positively heard on orbit. The spacecraft automatically relays images and telemetry to its ground network, which posts them to social-media platforms whenever a pass is received. European stations reported early carrier traces shortly after deployment, and the first confirmed CW beacon—sent at 16 WPM under the callsign “WP2XGW”—was received at approximately 14:46 UTC. SilverSat uses a UHF turnstile antenna oriented perpendicular to its magnetically stabilized axis, producing LHCP reception for most northern observers.

The 08:20 UTC deployment batch also included RHOK-SAT, Content-Cube, and a 1U CubeSat from Cornell University carrying a brief-duration light-sail experiment designed by students at the Space Systems Design Studio. The sail will be released during a later activation sequence following the CubeSat’s deployment and carries several ChipSat flight computers intended to transmit LoRa telemetry in the 70 cm amateur band during a short operational period. Because the timing of the sail’s release depends on mission conditions, additional details about the project and its ChipSat technology are available at alphacubesat.cornell.edu. Telemetry downlinks for this group include 435.425 MHz for RHOK-SAT (9600 FSK), 437.020 MHz for Content-Cube (9600 GMSK), and 437.400 MHz for the ChipSats, which may remain active only for hours to a few days before re-entry.

The two 3U satellites, EagleSat-2 and Foras Promineo, completed the deployments at 09:50 UTC. EagleSat-2, developed by undergraduate students at Embry-Riddle Aeronautical University, carries two scientific experiments: the Cosmic Ray Payload, designed to track high-energy particle interactions across three observation phases, and the Memory Degradation Experiment, which compares radiation-induced error rates in several CMOS memory technologies. EagleSat-2 transmits on 437.165 MHz using 19k2 2-GFSK. Foras Promineo supports a public-outreach mission based on an interactive robotic-arm game that operates autonomously or under real-time command during ground passes, transmitting LoRa telemetry on 437.400 MHz.

As of the first day of operations, SatNOGS contributors reported active tracking of all five amateur satellites using preliminary TLEs derived from ISS deployment vectors. With the objects initially clustered closely together, early identification required coordinated Doppler measurements and community-supported observation campaigns. As tracking continues to refine and the satellites separate further, operators can expect more reliable beacon reception and additional opportunities for amateur participation as the missions begin their operational phases.

ARISS Moves Series 30 SSTV Transmissions to RS-38S After Equipment Issue

Amateur Radio on the International Space Station (ARISS) has released final scheduling details for the Series 30 Slow-Scan Television retransmission event, which will take place using the RS-38S satellite rather than the ISS. Transmissions are scheduled to begin on 5 December at 00:01 UTC (4 December at 7:01 PM ET) and continue through 13 December at 23:59 UTC. The images will be broadcast from RS-38S, also known as VIZARD-meteo and listed under NORAD 57189, on a downlink of 437.825 MHz with normal Doppler adjustments. Each image will be sent in Robot 36 mode for approximately 36 seconds, followed by a silence period of two to three minutes. Operators may upload their received images to the ARISS SSTV gallery to obtain a new Series 30-1 certificate tailored for the RS-38S event. The satellite can be monitored on amsat.org/status under its VIZARD-meteo entry, and pass-prediction tools are available at amsat.org/pass-prediction for those planning reception attempts.

The RS-38S retransmission provides amateurs an opportunity to receive all 12 Series 30 images after the ISS-based event in November was interrupted by a hardware issue. ARISS announced on 29 November that the RS-38S spacecraft would transmit the same Series 30 imagery during the period of 5–13 December, offering a complete replacement opportunity. This announcement was well received by participants who were unable to capture images during the short ISS transmission window on 12 November. As with previous SSTV events, stations may submit their best frames to the ARISS gallery and request corresponding certificates. The retransmission preserves the commemorative nature of Series 30 while operating entirely independent of ISS hardware. ARISS encourages operators worldwide to monitor its official channels for updates throughout the event period.

The satellite-based activity follows a series of technical difficulties that prevented completion of the original Series 30 event aboard the International Space Station. The ISS transmissions began on 12 November with approximately two hours of successful downlink activity, during which several stations worldwide decoded and uploaded clean images. Soon afterward, SSTV activity on 145.800 MHz FM abruptly stopped, prompting ARISS to acknowledge the outage and begin checking the system status with operations teams on the ground. Crew schedules and limited immediate access to the Service Module hardware initially slowed the troubleshooting process. Operators monitored the downlink throughout the day, but no additional frames were received. ARISS provided real-time updates confirming the outage and advising listeners that further checks were underway.

By 15 November, ARISS reported that the SSTV system had remained offline since the initial interruption and that ongoing solar activity added complexity to assessments of the Service Module equipment. U.S. teams awaited additional information, and only the early decodes from the opening hours of the event appeared in the official SSTV gallery. ARISS thanked operators for their continued patience and reminded them that certificates would still be issued for the initial images. Amateur radio stations worldwide continued to submit signal reports and monitor each ISS pass in hopes of renewed activity. Despite broad interest, no additional transmissions were detected. ARISS stated it would continue providing updates as new information became available.

On 16 November, after three days of analysis, ARISS confirmed that the ISS-based Series 30 event could not continue. The Kenwood D710GA transceiver in the Zvezda Service Module, which supports SSTV operations, appeared to have failed and was taken offline for further review. ARISS reported that the radio functioned normally for approximately two hours before the issue occurred, ending downlink activity for the remainder of the planned 12–20 November window. Operators who received images early in the event were encouraged to upload their frames before the submission deadline to qualify for Series 30 certificates. ARISS emphasized that those certificates would still be honored despite the shortened schedule. No additional transmissions were expected until testing of the affected hardware could be completed.

A follow-on update on 21 November clarified the status of the Service Module radio system. ARISS reported that the faulty Kenwood D710GA had been replaced with the onboard spare Kenwood D710E, which is now supporting scheduled Russian school contacts and required backup communications. Additional in-orbit testing of the original D710GA is planned to determine the cause of the failure and evaluate when APRS or SSTV capabilities might be restored. ARISS also confirmed that the Columbus module radio systems, including the cross-band FM repeater and HamTV equipment, continue to operate normally. Restoration of SSTV service from the ISS will depend on the results of continued hardware assessments. Until those evaluations are complete, ISS-based SSTV remains offline, and the RS-38S retransmission provides the primary means for operators to receive the full Series 30 imagery.

Many times a school may make a last-minute decision to do a Livestream or run into a last-minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication.  You can always check https://live.ariss.org/ to see if a school is Livestreaming.

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 remains configured in the Columbus Module (145.990 MHz up {PL 67} & 437.800 MHz down). If a crewmember decides to pick up the microphone and turn up the volume, you may hear them on the air—so keep listening, as you never know when activity might occur.

The service module IORS is not currently in APRS configuration and is being used only for voice contacts at this time. HamTV in the Columbus Module is configured for scheduled digital amateur television operations on 2395.00 MHz.

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.

Registration is open for the 2025–2026 European Astro Pi Challenge

Educators: Do you want to send your students’ computer programs to space with the European Astro Pi Challenge? Astro Pi Mission Zero and Mission Space Lab are now officially open for the 2025–2026 challenge.

Astro Pi is an ESA Education project run in collaboration with the Raspberry Pi Foundation and delivered nationally by the European Space Education Resource Offices (ESERO).

The project offers different levels of complexity:

Mission Zero – for beginners (up to 19 years old) to learn to write a simple program that will run in space. Mission Zero, well suited for beginners, offers a chance for young people to create a piece of pixel art and have it displayed for astronauts to see on two special Raspberry Pi computers, called Astro Pis, aboard the ISS. The deadline for Mission Zero submissions is 23 March 2026.

Mission Space Lab – for more experienced coders (up to 19 years old) to carry out a scientific task using a program that will run in space. For more experienced coders, Mission Space Lab returns with a real-world scientific task: calculate the speed of the ISS as accurately as possible using the Astro Pi’s sensors or camera. Teams of two to six young people need to write a Python program that collects data from the Astro Pi computers on the ISS to perform this calculation.

Every team that submits a program that complies with the official guidelines will be awarded a participation certificate.The submission deadline for Mission Space Lab is 16 February 2026.

What is Astro Pi?

The European Astro Pi Challenge, or Astro Pi for short, is a free educational project. It has two missions that young people up to 19 years old can participate in, depending on their programming abilities. Both missions use Python programming to create short computer programs that will be run on the International Space Station (ISS).

The Astro Pi school project platform offers educators a comprehensive suite of resources to engage students in space science and coding activities, as well as support and community engagement activities.

Optical Communications Systems Test the Limits of FCC Authority

As the U.S. regulator of non-Federal radio spectrum, the FCC has become one of the most important overseers of commercial space activity. No satellite system can realistically gain access to the U.S. market without prior FCC approval and oversight: the agency licenses space and Earth stations and coordinates U.S. filings with the International Telecommunication Union (ITU).

But optical communications systems—particularly optical ground stations—do not fit neatly within the FCC’s statutory authority to regulate communications by “wire or radio.” Optical transmissions are not “radio.” Rather, free-space optical communications, or “lasercoms,” use optical wavelengths—generally in the near-infrared portion of the spectrum—to transmit data between user terminals.

Traditionally, satellite communication systems have relied on radio frequency (RF) transmissions within designated spectrum bands to relay signals either between satellites or from satellites to Earth. While these systems remain reliable and widely used, RF spectrum has inherent limitations – most notably finite bandwidth, increasing congestion, and atmospheric attenuation.

Optical communications offer a different path. By transmitting optical wavelengths, typically in the near-infrared range, free-space optical links can provide much higher data rates than RF.

One key component is the optical ground station. Unlike a traditional RF ground station with a dish antenna, an optical ground station uses a telescope and optoelectronic components to transmit and receive laser signals.

Still, lasercom poses unique technical challenges. The same narrow beam that enhances security also imposes constraints: RF signals can blanket wide areas.

Atmosphere attenuation also remains a major challenge to lasercom: atmospheric attenuators such as dust, smoke, fog, haze, and inclement weather impair the technology’s ability to transmit information.

The FCC has long indicated that it does not have jurisdiction over optical inter-satellite links because they do not involve RF spectrum. If the FCC lacks authority over lasercom, it might be unable to apply licensing requirements, enforce technical standards, or impose other space access conditions such as orbital debris mitigation plans and post-mission disposal requirements.

Uncertainty also carries real risks – operators do not know whether FCC licensing will eventually be required, what conditions might apply, or whether or how the U.S. might ultimately coordinate internationally. Lack of clarity could also complicate global harmonization: other jurisdictions may set their own rules, creating inconsistent standards.

A Protocol Extension for GOLF Operations

At the recent AMSAT Space Symposium held in Phoenix, Arizona, AMSAT Software Engineer Heimir Thor Sverrisson, W1ANT/TF3ANT, presented on the protocol extension he has been developing for satellite command and control systems, focusing specifically on improvements needed for the GOLF satellite project. The existing setup, utilizing the AMCOM program, has been successfully operational since 2015, primarily employing straightforward commands such as those for transitioning the spacecraft into safe or health modes. However, the GOLF project necessitates a more complex command structure to handle longer payloads, especially those involving Automated Thermal Controls (ATCs), which require orbital parameters to be sent as a cohesive unit.

The discussion underlined the importance of maintaining the proven AMCOM infrastructure, proposing to leverage existing telemetry tools like FoxTelem. The proposal includes utilizing five bits of telemetry data to provide feedback on command status, thus ensuring that commands are transmitted successfully and effectively, addressing the limitations of the current system.

A pivotal part of the discussion revolved around the concept of “multipart commands.” Heimir illustrated a plan to modify the AMCOM command structure to allow the transmission of multiple segments in a single command, using a sequential numbering system to keep track of these packets. The extension would also involve designating specific bits to indicate whether a command is multipart and which piece of the command is being acknowledged or is missing.

Heimir elaborated on the technical elements of the transmission protocol, detailing how to manage packet loss and potential sequence issues via a robust acknowledgment system. The system would require two threads of execution at the ground station — one for sending commands and another for handling incoming telemetry. This dual threading is crucial as it allows for more efficient communications and processing, maintaining system integrity in the event of packet loss or transmission delays.

A key component of the protocol will be adjusting how command data is structured and transferred, with new formats proposed for command definitions. The transition from a CSV format to a more flexible and human-readable JSON format was suggested to accommodate the new capabilities, making it easier for engineering teams to integrate the changes into their workflows.

The presentation included a demonstration of a simulator designed to visually represent the command transmission process, showcasing how the protocol would function under various conditions, including different rates of packet loss. The simulator was created in Python and is hosted on Heimir’s GitHub repository, making it accessible for further exploration.

During the question and answer section, audience members raised concerns related to the security of satellite communications, particularly regarding potential cyber threats. Heimir reassured participants that encryption and digital signature protocols are already in place for uplink communications, although downlink encryption remains restricted by FCC regulations against obscured transmissions.

The meeting concluded with a reflection on the practicality and challenges of implementing these proposed changes, emphasizing the continuous need for advancements in satellite communication protocols to cater to growing operational complexities and security requirements. Follow-up actions were identified, including finalizing the simulation details and incorporating feedback from the engineering team into the command structure proposal. Thankful remarks were exchanged, acknowledging the collaborative efforts required for successful implementation.

REALOP CubeSat to Test Hard Drives for ADC System

The University of California, Davis will fly its REALOP 2U CubeSat mission with two goals in mind.

The primary goal of the mission will be to provide students with the educational opportunity to design, build, and test a satellite. Students will gain hands-on knowledge of the different subsystems of the satellite and they will learn about the use of amateur radio and how to use RF in order to communicate with spacecraft.

The secondary goal of the mission is to demonstrate the feasibility of using hard disk drives as a low cost alternative to reaction wheels for CubeSat attitude detection and control. This has the potential to reduce the financial barrier of entry into CubeSat development.

A UHF GMSK downlink with a 96 kHz symbol rate on 437.400 is proposed. Telemetry packets will use HDLC framing and a rate 1/2 convolutional forward error correction. Deployment from the ISS is planned for June 2026.

Happy 12th Birthday to AO-73 (FUNcube-1)

AO-73 celebrated its 12th birthday on November 21, 2025. The satellite is still operating well in full-time transponder mode.

On November 21, 2013 FUNcube-1 (AO-73) was launched from the Yasny launch base located in the Orenburg Region, Russia on a Dnepr Launch Vehicle into a 600 km, 97.8º inclination sun-synchronous orbit. In this orbit the satellite passes over the British Isles and Europe approximately 3 times in the morning, and 3 in the evening, every day, perhaps allowing the morning passes to be used for educational purposes and the evening passes for Amateur Radio communications.

FUNcube carries a UHF to VHF linear transponder that has 300 mW PEP output and which can be used by Radio Amateurs worldwide for SSB and CW communications.

Communication subsystem:
• 145.935 MHz BPSK Telemetry 30/300 mW
• Inverting SSB/CW transponder 300 mW
– 435.150 – 435.130 MHz Uplink
– 145.950 – 145.970 MHz Downlink

The passband may be up to 15 kHz higher depending on on-board temperatures. Low temperatures give higher frequencies

As of writing, ground stations from around the world have collected 11,631,536 frames of telemetry throughout the satellite’s life. The satellite’s recently received telemetry values can be found on AMSAT-UK’s Data Warehouse at http://data.amsat-uk.org/ui/fc1-fm.
