    ARISS - Amateur Radio on the ISS
    @ARISS_Intl
    Mar 4
    ARISS is plotting a course to continue our mission in the government and commercial space realm beyond the targeted decommissioning of the ISS in the 2030 timeframe. Read more about our activities in these infographics, and in a blog post at ariss.org.
    Infographic from ARISS showing the future of ham radio beyond the ISS: Rabea Rogge on Fram2 mission (top selfie, April 2025) transmitting SSTV from polar orbit, and Axiom Mission 4 crew (bottom) conducting STEM contacts. Text highlights ARISS expanding to commercial space vehicles like SpaceX Dragon and Axiom missions.
    Infographic titled 'ARISS beyond the ISS' with subtitle 'When all else fails: ham radio is ready!' It shows a photo of the ARISS Interoperable Radio System (IORS) ground spare hardware setup, including a Kenwood radio (displaying CH 201/CH 202), antennas, cables, power supplies, and connectors on a table at an event. Main text explains that commercial space station builders are interested in ham radio as a tried-and-true backup communications method for new facilities. ARISS can provide: flight-certified hardware, proven outreach practices (engaging more than 40,000 youth each year), a morale booster for crews, and space-based learning experiences. It notes active discussions on future partnerships. Bottom features the ARISS logo with 'Amateur Radio on the International Space Station'
    Infographic titled 'ARISS beyond the ISS' with subtitle 'AREX teams will track ARTEMIS II mission telemetry.' It features a large photo of NASA's Artemis II SLS (Space Launch System) rocket with Orion spacecraft on the launch pad during rollout in February 2026, showing the tall orange-and-white rocket stacked vertically on the mobile launcher, surrounded by the launch tower structure at Kennedy Space Center, with a person in a high-visibility vest nearby on the ground. Main text explains that NASA's Artemis II mission offers ARISS and AMSAT teams an opportunity to participate again in human spaceflight activities. AREX is a joint ARISS-AMSAT project to develop radio systems and payloads for Moon and Mars missions. First steps involve collaborating with NASA SCaN to demonstrate passive tracking of the upcoming lunar mission. It notes NASA SCaN as an ARISS sponsor. Bottom includes the ARISS logo with 'Amateur Radio on the International Space Station' and an Artemis graphic overlay.

    A proud moment for ARISS! ARISS representatives Frank Bauer and Jackie Blumer accepted the Challenger-7 Recognition from Challenger Center's Mike Kincaid during the organization's 40th Anniversary celebration. Thank you for this honor and for supporting STEM inspiration
    Graphic announcing ARISS receiving Challenger-7 Recognition during the Challenger Center 40th Anniversary contact event. The left side shows the Challenger Center 40th anniversary logo with the years 1986-2026 against a star-filled space background. The right side contains text noting that ARISS was honored with the recognition and thanking the Challenger Center team for selecting ARISS. A quote from ARISS International Chair Frank Bauer, KA3HDO, states that ARISS astronaut experiences reflect the Challenger crew’s spirit of exploration and education by engaging and inspiring the next generation of STEM explorers and preparing them for future STEM careers. The ARISS logo appears at the bottom right.

    ARISS radio outage upcoming. The cross-band voice repeater and packet radios will be off next Mon-Wed in support of the space walk from the ISS. Just curious, what do y'all do when the ARISS radios are off? Reply and share your activities!
    ARISS outage notice graphic. On the left, a NASA image shows a spacewalker outside the International Space Station with Earth visible in the background. On the right, text announces an upcoming outage from August 17–19, 2026. The Columbus Module Radio cross-band voice repeater and Service Module Radio APRS Packet/SSTV will be off beginning Monday, August 17 at 19:05 UTC (3:05 PM ET) and return on Wednesday, August 19 at 10:40 UTC (6:40 AM ET). The graphic notes that HamTV is not expected to be impacted and that all times are approximate and dependent on other spaceflight activities. ARISS logo at lower right.

    1 hour until contact with Massachusetts! STEM education leaders from Challenger Center will talk with Sophie Adenot on the ISS live via ham radio. Scheduled today at 16:31 UTC | 12:31 PM ET via VK4ISS telebridge in Australia. Listen on 145.800 MHz FM.
    Graphic announcing an upcoming ARISS school contact. On the left, a photo shows an ISS crew member floating inside the International Space Station, holding a handheld radio microphone with hair floating upward in microgravity. On the right, text reads: “Contact Upcoming. Challenger Learning Center National Conference, Framingham, Mass., USA. Wednesday, 12 August. 16:31 UTC | 12:31 PM ET.” The graphic states that ISS crew member Sophie Adenot, KJ5LTN, will use the NA1SS callsign, with VK4ISS in Australia serving as the telebridge ground station. Listening frequency is 145.800 MHz FM. A note at the bottom says the cross-band voice repeater will be offline for this event. The ARISS logo appears in the lower-right corner.

    Every year, ARISS helps make 60 to 100 amateur radio contacts between the International Space Station crew and STEM education communities worldwide. Could your school, scouting organization, planetarium, museum, or youth group be next? Start your proposal today!
    Graphic explaining regional application windows for ARISS STEM education contacts with the International Space Station crew. The left side shows the ARISS globe logo over a star-filled space background. The right side lists application information by region. United States: submit proposals to ARISS-USA by September 30 for contacts in January-June 2027. Europe, Africa, and the Middle East: apply to ARISS-Europe from September 1 to October 23 for contacts in July-December 2027. Americas (except the United States): apply to ARISS-Canada at any time. Asia, Pacific, and Australia: apply to ARISS-Japan at any time. Russia: apply to ARISS-Russia at any time. Text at the bottom reads, “Visit ARISS.org to take the next step toward your contact!”
