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 education@ariss-usa.org .

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.  [ANS thanks NASA-TV for the above information.]

 

+ A new version of the Andy UZ7HO SoundModem program for HADES-SA SpinnyONE is now available, fixing several detected bugs.

You can download it at: https://www.amsat-ea.org/app/download/14224014/UZ7HO_Soundmodem_for_HADES_SA_SpinnyONE.zip.
