ARISS Proposal Window Open Now through September 30, 2026

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 January 1, 2027 – June 30, 2027. 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 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.

Proposals are due to ARISS by September 30, 2026, at 11:59 PM Pacific Time. To help you get started, an informative video is available at youtube.com/arisslive. Detailed guidelines and expectations can be found at ariss.org, and the proposal form is available via the online ARISS Contact Application.

European Astro Pi Challenge 2026/27 Registration Opens September 14, 2026

Mission Space Lab invites young people to run their own code on the International Space Station (ISS), giving them an opportunity to conduct science in space. Teams write a Python program that captures sensor data from Raspberry Pi computers on board the ISS to use in space science projects.

What is Mission Space Lab?
Working in teams, young people will write a program to collect data from the Astro Pi computer’s sensors or camera, logging the results to a file. By analyzing atmospheric readings or capturing images of Earth from 400km above, they can investigate everything from life on our planet to the mechanics of orbital space flight.

Photo courtesy raspberrypi.org.

What can a team investigate? Teams can design an entirely original space science project or follow one of our ready-made project guides to get started.

Every eligible program is given a 10-minute slot on the ISS. Once the mission is complete, successful teams will receive official certificates showing the exact time and geo-coordinates when their code ran. They’ll also receive their own data and image sets to download, keep, and analyze!

Who Can Take Part?
Mission Space Lab is designed for young people who have some basic coding experience. We recommend this mission for young people aged between 12 and 19. They will use their knowledge to investigate real space science using a program they write themselves. Project guides are available to support teams in creating their program.

Why take part?
Participating in Astro Pi Mission Space Lab empowers young people to learn about life on the ISS, discover how to gather and utilize data in space, and master the art of creating and troubleshooting a computer program. Best of all, teams have the opportunity to capture unique Earth observation images and space data to keep forever!

Registration is open from Monday 14 September 2026 to Monday 22 February 2027, 12:00 CET.

Astro Pi is an ESA Education project run in collaboration with the Raspberry Pi Foundation.

Call for Presentations: 44th AMSAT Space Symposium

Do you have a story to tell the amateur satellite community? AMSAT invites proposals for presentations at the 44th AMSAT Space Symposium and Annual General Meeting, to be held October 8-11, 2026, at the Wyndham Jacksonville Hotel & Conference Center in Jacksonville, Florida.

Presentations are welcome on any topic of interest to the amateur satellite community. Suggested subjects include current and future satellite projects such as the GOLF program and the CubeSatSim; ARISS and human spaceflight activities; ground station, antenna, and portable station design; software-defined radio; telemetry collection and analysis; satellite operating techniques and achievements; educational programs and youth outreach; and reports from DXpeditions and roving operations. Whether you have built it, flown it, coded it, taught it, or worked it through a satellite, your fellow attendees want to hear about it.

Prospective presenters should email a tentative presentation title and a brief abstract to symposium [at] amsat.org as soon as possible. Presentation time slots are limited, so early submissions are encouraged, and information on submitting final papers and presentation materials for inclusion in the Symposium Proceedings will be provided to presenters. A digital copy of the Proceedings is included with every Symposium registration.

Symposium presentations begin Friday afternoon, October 9, and continue through Saturday, October 10, leading into the Annual General Meeting. Live streaming will bring the sessions to members unable to attend in person – all the more reason to make sure your work is on the program.

Registration for the Symposium is now open at https://launch.amsat.org/event-6789663, with early bird pricing available through September 8. Hotel reservations at the Wyndham Jacksonville – the property formerly known as the Crowne Plaza Jacksonville Airport/I-95 – may be made through the booking link at https://www.amsat.org/2026-amsat-symposium/ or by phone at 1-800-227-6963 using group code AMS.

How Cell-Phone Technology Revolutionized Amateur Satellites

Cell-phone technology has played a major role in the development of today’s small satellites and CubeSats. Smartphones require components that are small, lightweight, inexpensive and power-efficient—the same qualities satellite designers need.

Because billions of phones and other portable devices are manufactured, sophisticated electronic components that once were extremely expensive are now available as commercial off-the-shelf (COTS) products.

Smartphone-class processors give small satellites substantial computing power for controlling experiments, processing images and compressing data. Miniature CMOS cameras can provide Earth imagery, while MEMS accelerometers and gyroscopes help determine a spacecraft’s movement and orientation. Compact GPS receivers provide position and timing information, and inexpensive flash memory can store large quantities of images and scientific data for later transmission.

Advances in compact radio-frequency electronics and digital signal processing have also allowed sophisticated communications systems to fit inside CubeSats. Meanwhile, improvements in lithium-ion batteries provide lightweight rechargeable energy storage.

Traditional spacecraft often use expensive radiation-hardened electronics designed specifically for space. CubeSat builders can sometimes substitute commercial components, reducing costs dramatically while using shielding, redundancy and software to compensate for increased risk.

NASA demonstrated the potential of consumer electronics with its PhoneSat program. Beginning in 2013, PhoneSat spacecraft used Android smartphones as important parts of their onboard systems, taking advantage of their processors, cameras and sensors.

The greatest contribution of the smartphone industry may therefore be the philosophy of packing tremendous capability into very little space while consuming minimal power.

For amateur-radio and university satellite builders, this has been especially important. A modern CubeSat can combine a computer, radio, GPS receiver, cameras, sensors and telemetry system in a spacecraft small enough to hold in your hands.

Changes to AMSAT TLE Distribution for August 28, 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.

SpaceX Plans Massive New Launch Facility in Louisiana

SpaceX has announced plans to build what could become the world’s largest commercial space launch facility along the Louisiana Gulf Coast. The proposed $100 billion development, known as Starbase Louisiana, would be located on approximately 125,000 acres near Pecan Island in Vermilion Parish.

The new spaceport would become SpaceX’s fourth and largest U.S. launch site and would primarily support the company’s enormous Starship rocket. At full development, plans call for five launch complexes, each containing two launch pads and associated propellant facilities. The site would also include rocket processing facilities, power generation, methane propellant production, employee housing and deep-water shipping capabilities.

Image courtesy SpaceX.

SpaceX ultimately envisions launching Starships from Louisiana thousands of times each year. Starship is being developed as a fully reusable transportation system capable of carrying satellites, cargo and people into Earth orbit and eventually to the Moon and Mars. The Louisiana location provides several advantages, including extensive undeveloped land, access to Gulf shipping routes and abundant natural gas resources that could support power generation and methane production.

Louisiana officials estimate that the project will create about 3,000 direct jobs during its first decade, with an average annual salary of approximately $92,600. Another 8,100 indirect jobs could be generated throughout the Acadiana region. Construction is expected to begin in 2027, with the first launch possible as early as 2029.

The ambitious project will also face environmental scrutiny. The proposed site contains sensitive coastal wetlands and important migratory-bird habitat. Environmental organizations have called for careful permitting and public review. SpaceX says much of the property will remain undeveloped and that it intends to work with government agencies on marsh restoration, shoreline protection and wildlife conservation.

If completed as planned, Starbase Louisiana could transform the state into one of the most important centers of commercial spaceflight in the world.

2026 AMSAT Field Day Update

It’s that time of year again; summer and Field Day! Each year the American Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!” The event takes place during a 27-hour period on the fourth weekend of June.

For 2026 the event takes place from 1800 UTC on Saturday June 27, 2026 through 2100 UTC on Sunday June 28, 2026. Those who set up prior to 1800 UTC on June 27 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event.

This year should be as much fun as last year since we have more than 10 transponders and repeaters available. For AMSAT purposes, a transponder on a satellite would count as two if you could do phone and CW. We count them by modes, not the satellite names.

Users should check the AMSAT status page at http://www.amsat.org/status/ and the pages at https://www.amsat.org/two-way-satellites/ for what is available in the weeks leading up to field day. To reduce the amount of time to research each satellite, see the current FM satellite table at https://www.amsat.org/fm-satellite-frequency-summary/ and the current linear satellite table at https://www.amsat.org/linear-satellite-frequency-summary/ .

If you are considering ONLY the FM voice satellites, there are ISS and SO-50. It might be easier this year to make that one FM contact for the ARRL bonus points with so many FM birds. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice.

It was suggested during past field days that a control station be allowed to coordinate contacts on the FM satellites. There is nothing in the rules that would prohibit this. This is nothing more than a single station working multiple QSO’s. If a station were to act as a control station and give QSO’s to every other field day station, the control station would still only be allowed to turn in one QSO per FM satellite while the other station would be able to submit one QSO.

The format for the message exchange on the ISS or other digital packet satellite is an unproto packet to the other station (3-way exchange required) with all the same information as normally exchanged for ARRL Field Day, e.g.:

W6NWG de KK5DO 2A STX
KK5DO de W6NWG QSL 5A SDG
W6NWG de KK5DO QSL

If you have worked the satellites on Field Day in recent years, you may have noticed a lot of good contacts can be made on some of the less-populated, low-earth-orbit satellites like AO-7, RS-44, AO-73, FO-29 and JO-97. During Field Day the transponders come alive like 20 meters on a weekend. The good news is that the transponders on these satellites will support multiple simultaneous contacts. The bad news is that you can’t use FM, just low duty-cycle modes like SSB and CW.

CardSat: A Pocket Satellite Tracker and Doppler Controller

Paul Stoetzer, N8HM, has released CardSat, a free, open-source amateur satellite ground station controller that runs on the M5Stack Cardputer ADV – a credit-card-sized ESP32-S3 computer with a built-in keyboard, color display, and microSD slot. The project lives at https://github.com/prstoetzer/CardSat.

CardSat downloads GP orbital and transponder data over WiFi, predicts passes locally with SGP4, and drives a radio over CAT with real-time Doppler correction. It works fully offline once data is cached and deep-sleeps between passes to save battery.

Its Doppler engine uses the AMSAT “One True Rule” correcting both uplink and downlink so your signal holds the same spot in the passband for the whole pass. You can tune with the Cardputer keys or the radio’s own knob – CardSat follows the dial and re-applies correction with nothing drifting.

Radios: Ten rigs across three CAT families – Icom CI-V (IC-820/821/910/970/ 9100/9700), Yaesu (FT-847, FT-736R), and Kenwood (TS-790, TS-2000) – plus native Icom LAN (RS-BA1) control of a networked Icom IC-9700 over WiFi. Linear-transponder passband tracking, automatic sideband selection, and automatic FM CTCSS tones are included. CardSat can also act as a rigctld/rotctld server for a PC, or as a rigctl client to a remote rig.

Operating and planning: An all-favorites Next Passes schedule, an AOS alarm, deep-sleep until AOS, elevation and polar plots with ground track, sun/eclipse status, a mutual-window finder for co-visibility with a remote station, a 10-day pass overview, a 60-day illumination raster, a time-step simulation, and a multi-page orbital analysis (including beta angle and decay).

Award chasing: CardSat lists what’s under the footprint right now – workable grid squares (VUCC), US states (WAS), and the full 340-entity DXCC list (major countries as polygons, island/micro-entities by reference point from cty.dat) – live or as a per-pass union.

Plus: Az/el rotator control (GS-232, rotctl, PstRotator, or direct Yaesu) with park, pre-position, per-pass flip, and manual jog; Sun/Moon pointing for sun-noise and EME aiming; QSO logging with ADIF export that doesn’t interrupt Doppler; AMSAT OSCAR Status activity marks; a world map with all footprints; a GPS sky plot; selectable element sources; on-device help; and screenshots.

The Cardputer ADV uses an ESP32-S3 (4 MB flash, no PSRAM, 240×135 LCD, 56-key keyboard). Controlling a radio requires a CAT interface suited to the rig; the 3.3 V GPIO is not 5 V tolerant, so CAT lines must never be wired direct.

Status: CardSat builds and runs on the Cardputer, with pass prediction, the plots, mutual-window search, GPS, the AOS alarm, deep sleep, and the offline caches all confirmed on hardware. The CAT frequency encoders, the Icom LAN backend, the rotator backends, and the network server/client paths are implemented and host-tested but have not yet driven a real radio or rotator on the air. Operators willing to test these paths and report results are encouraged to do so.

The repository includes firmware, a full manual, wiring guides, and a printable key-reference card.

NASA Honors AMSAT-DL for Contribution to Artemis II Mission

AMSAT-DL was pleased to announce that it had received a Certificate of Recognition, an official certificate of appreciation, from NASA for its participation in the Artemis II mission.

Passive Tracking of the Orion Spaceship
As part of the historic Artemis II mission, the AMSAT-DL and Bochum Observatory successfully tracked the Orion spacecraft passively throughout. Over 6 TB (terabytes) of IQ data and Doppler measurements were recorded. This achievement was expressly acknowledged by NASA, as it impressively demonstrates the contribution that radio amateurs and civil society organizations can make to modern space travel – far beyond the capabilities of traditional government systems.

An Award for the Entire Community
The certificate, signed by Marta Shelton, CIS Office Chief of NASA Space Communications & Navigation (SCaN), is dated April 24, 2026 and recognizes AMSAT-DL’s “diligent efforts and success in the passive tracking of the Orion spacecraft.” Most significantly, the certificate also names the crew of the Artemis II mission: Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen. This honor belongs not only to AMSAT-DL as an organization – it belongs to all the members, supporters and volunteers whose passion for amateur radio and spaceflight made this success possible.

Amateur Radio and Space Travel – A Strong Connection
The award from NASA is impressive proof that amateur radio continues to play an important role in space communication and monitoring in the 21st century. AMSAT-DL and Observatory Bochum remain true to their shared mission: to promote the link between amateur radio and space exploration and to inspire the next generation of radio amateurs and space enthusiasts.

Peter Gülzow DB2OS, AMSAT-DL comments, “We would like to thank NASA and the SCaN team for this great recognition of our work – and look forward to accompanying future missions on the way back to the moon!”

  • California Polytechnic State University has received frequency coordination for a mission named “Additively Manufactured Deployable Radiator with Oscillating Heat Pipes. The primary objective of the AMDROHPSat mission is to perform an on-orbit technology demonstration of the Additively Manufactured Deployable Radiator with Oscillating Heat Pipes (AMDROHP). This 3U CubeSat experiment seeks to validate the ability of a novel, student-integrated thermal system to reject up to 50W of heat in Low Earth Orbit. The mission’s secondary objective is to facilitate learning by doing and self-training for the student team. After the launch and early operations phase has concluded, payload deployment will occur and a digipeater will be enabled. A UHF downlink using 9k6 GFSK will be set for 436.860. The launch is planned from KSC on NG25 NET in December 2026 to the ISS. More info at https://www.polysat.org/. [ANS thanks AMSAT-UK and the IARU for the above information.]
  • The crew of NASA’s next Artemis moon program mission was announced Tuesday, setting the stage for a flight to Earth orbit next year to test rendezvous and docking procedures with moon landers being built by SpaceX and Blue Origin, a critical milestone before sending astronauts back to the moon for landing in 2028. The Artemis III mission will be commanded by Randy “Komrade” Bresnik, 58, a former Marine fighter pilot and “TOPGUN” graduate who logged 149 days in space during a space shuttle flight in 2009 and a long-duration stay aboard the International Space Station in 2017. Joining him will be pilot Luca Parmitano, 49, KF5KDP, a European Space Agency astronaut and veteran of two long-duration stays aboard the space station; Andre Douglas, 40, a space rookie and backup crew member for the recently completed Artemis II around-the-moon mission; and Frank Rubio, 49, who spent a U.S.-record 371 days in space aboard the ISS in 2022-23.

ARISS Solicits School Contacts for 2007

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 January 1, 2027 – June 30, 2027. 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.

This proposal is due to ARISS by May 22, 2026 at 11:59 PM Pacific Time. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at https://www.ariss.org. An informational webinar will be held at 8 PM ET on April 30. The zoom link for that webinar is https://us06web.zoom.us/meeting/register/3yid9dxzRkmYfVroIP0nWA .

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.

Please direct any questions to [email protected] .

​ARISS and AMSAT: On Track to Track Artemis 2

When the Artemis 2 mission with four astronauts departs for deep space sometime in April, a team of ARISS and AMSAT volunteers will be “watching” from afar. Specifically, our experts will use a multinational network of ground station receivers to capture the Orion capsule’s one-way S-band communications with mission control as a secondary means of tracking the spacecraft.

While NASA’s Space Communications and Navigation (SCaN) program will depend on the Near Space and Deep Space Network for primary tracking of the Orion during its 10-day mission around the moon and back, it has also selected 34 individuals and groups (including an ARISS and AMSAT consortium) across 14 countries to provide an independent source of tracking data using the radio waves generated by normal communications.

(Credit: NASA/John Kraus)

The concept works. For Artemis 1, an uncrewed launch into low-Earth orbit in 2022, 10 individuals successfully tracked Orion throughout its mission. Based on lessons learned from that experience, SCaN now has data standards that Artemis 2 passive trackers will use when sending the data to NASA.

Another lesson SCaN learned from Artemis 1 was that there is a lot of interest in passive tracking. SCaN in August 2025 issued an official request for information (RFI) to government agencies, companies, amateur radio organizations and enthusiasts to participate in Artemis 2 tracking. According to NASA, those chosen through the RFI will use 47 ground assets in 14 countries to help the agency “better assess the broader aerospace community’s tracking capabilities and identify ways to augment future Moon and Mars mission support.”

ARISS and AMSAT are teamed up under the auspices of the AREx (Amateur Radio Exploration) Ground Station Consortium. AREx is a joint ARISS and AMSAT international effort to develop and operate amateur radio systems for deep space, starting at the moon and later to Mars. The team will provide one-way doppler tracking of the S-band signals from space, recording the data and delivering it to SCaN in the proper format.

The AREx worldwide consortium includes teams in the United States (University of Southern California, and Dayton, Ohio); the UK (Goonhilly); Germany, and Poland. Other AREx team members who supported the Artemis I initiative are also participating separately. ARISS operations team member Daryl Young is serving as the Project Manager for the Artemis 2 tracking project.

GridMasterMap Satellite Top 100 Rovers April 2026 Rankings

The April 2026 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in satellite operations, as determined by @GridMasterMap on Twitter, has been released as of April 3, 2026.

The ranking is determined by the number of grids and DXCC entities activated, taking into account only those grids where a minimum number of QSOs logged on the gridmaster.fr website have been validated by a third party. Grid numbers do not directly reflect the exact number of activations. Satellite operators are encouraged to upload their LoTW satellite contacts to https://gridmaster.fr in order to provide more accurate data.

Changes to AMSAT TLE Distribution for April 3, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

The following satellites have been added to this week’s AMSAT TLE distribution. They have provisional object numbers that will change once official USSF/NORAD numbers are assigned

HADES-SA/SpinnyONE Provisional ID 71958
LILIUM-4 Provisional ID 71922
PARUS-6U1 Provisional ID 71919
JACK-002 Provisional ID 71927
SAL-E Provisional ID 71904
DISCO-2 Provisional ID 71908

ARISS Plans SSTV Event for April

ARISS is planning for a 70cm (437 MHz) event for the week of April 12, 2026.

The ARISS teams are preparing a new series of SSTV transmissions for the event. The SSTV Series 31 images will pay tribute to Cosmonautics Day, the 100th anniversary of liquid-fueled rockets, the inaugural Space Shuttle launch and SuitSat.

Exact times, frequencies and modes will be announced closer to the event. Follow ARISS social media for updates.

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

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.

Satellite Shorts From All Over

The two-hour launch window of the Artemis II mission provided a practical example of the effects of space debris and satellite crowding. During the launch window, NASA was required to respect approximately 156 “cuts.” A cut is a period when the rocket could not be launched due to the risk of collision with a satellite or trackable debris in low-earth orbit. Each cut can last from one to twenty-three seconds. The NASA-TV commentator noted that it wasn’t many years earlier when the number of cuts for this type of mission was only in the forties.
