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.

As they used to say on Monty Python, "And now for something completely different..."

ARISS SSTV Series 35 has a surprise in store. Check the graphic for the spoiler alert!
Promotional graphic for ARISS SSTV Series 35. The left side shows the ARISS logo above large gold and white text reading "ARISS SSTV Series 35" with the International Space Station flying above Earth's horizon against a purple space-themed background. The right side contains a spoiler alert for the ongoing "Space Memories" SSTV event. It announces a surprise planned during the experiment and warns readers not to continue if they want to be surprised. The graphic reveals that at approximately 1600 UTC (11:00 AM ET) on Thursday, November 12, the current set of 12 SSTV images will be replaced with a completely new set of 12 images. The event remains a single SSTV activity with one participation award. Participants who want all images from the original set are encouraged to complete their collection before the changeover and then prepare to receive a fresh set of images from the International Space Station.

Still looking up.

On November 4, 1996, ARISS was founded through a partnership of international AMSAT organizations and national amateur radio societies. Thirty years later, that vision continues to inspire students around the world through connections with astronauts and
Today we celebrate 30 years of ARISS and look ahead to the future of amateur radio in human spaceflight.
Graphic commemorating the 30th anniversary of ARISS. The left side features two historic images from November 1996: a group photo of early ARISS participants gathered on a stairway and a sign reading “WORKING TODAY FOR TOMORROW ARISS.” Below is a large image of a reddish lunar eclipse moon against a dark night sky. The right side contains the headline “Still Looking Up” and the text: “30 years apart, radio amateurs still look to the skies.” A November 1996 section explains that ARISS was formed as a partnership between international AMSAT organizations and national amateur radio societies, establishing the foundation for amateur radio communications with the International Space Station. A November 2026 section states that the AREx team continues the tradition begun by ARISS volunteers 30 years earlier, exploring the future of amateur radio in human spaceflight, including lunar opportunities. An ARISS logo appears in the lower-right corner on a blue space-themed background.

Enjoy some fall reading! @rprogge's book, "A (little) Space for Everyone," is now available in English and German!

We're proud to have been part of her journey through the Fram2Ham mission, which made her (LB9NJ/KD3AID) the first amateur radio operator to make contacts from a t.
Graphic titled “Fram2Ham History” on a dark blue background. Two book covers by Rabea Rogge are shown on the left: the English edition, A (little) Space for Everyone: An Astronaut’s Thoughts on Robots, Exploration and the Meaning of It All, and the German edition, Ein (bisschen) Weltraum für Alle. Both covers feature a black-and-white space-themed illustration with an astronaut standing on a snowy or lunar-like landscape beneath a large celestial body. Text on the right announces a new book by Rabea Rogge about the Fram2Ham mission. It notes that Rogge was the mission leader and the first person to make a ham radio contact from a SpaceX Dragon spacecraft. The graphic highlights the book title, states that the German edition was published in April and the English edition in October, and encourages readers to find it at their favorite online bookstore. An ARISS logo appears in the lower-right corner.

The ARISS radio outage for the spacewalk has passed for this week, and ARISS radios are back in their "norminal" configurations. 😉

Another EVA is planned for Nov. 5, so a similar outage is expected next week. We'll share additional details as they become available.
Graphic titled “ARISS Frequencies.” The left side shows the International Space Station orbiting above Earth with the planet’s curved horizon visible in the background. The right side lists amateur radio frequencies in use on the ISS as of September 2026. The ARISS FM voice repeater transmits on 437.800 MHz and listens on 145.990 MHz using a 67 Hz CTCSS tone. The packet radio, currently set for UHF APRS, transmits and listens on 437.825 MHz. All ARISS STEM educational contacts use 145.800 MHz FM for transmissions from the ISS. HamTV transmits on 2.395 GHz in DVB-S format. The ARISS logo appears in the lower-right corner. A small photo credit notes: “NASA image of the ISS with the Earth in the background.”

During the Women and Girls in Astronomy Program (WGAP) gathering at UNAM earlier this month, Carlos Miranda, ARISS USA Dir of Education had the opportunity to share ARISS and its educational mission with an international network representing six countries across the Americas. opportunities for schools to participate in future ARISS contacts. One photo is from our group excursion to the ancient pyramids of Teotihuacan, where ARISS managed to make an appearance!
Three people stand in front of a large stepped stone pyramid at an archaeological site, holding small circular stickers or badges toward the camera. The pyramid’s steep central staircase is crowded with visitors climbing and descending. The three visitors wear casual outdoor clothing, hats, and conference-style badges. In the background, the massive stone structure rises under a bright blue sky with scattered white clouds. The foreground consists of a gravel plaza, emphasizing the scale of the ancient monument behind them.
