Re-post from ANS-313:
Amateur Radio on the International Space Station (ARISS) will commemorate the 25th anniversary of continuous human presence aboard the International Space Station with a special worldwide Slow-Scan Television (SSTV) event in mid-November. The ISS has been continuously inhabited since November 2, 2000, marking a major milestone in human spaceflight and international cooperation. ARISS, the first educational payload on the station, continues to play a key role in inspiring students, supporting STEM engagement, and connecting the global amateur radio community with astronauts in orbit.
The Series 30 SSTV event, titled “ISS at 25 and Scouts!” will feature 12 SSTV images celebrating the station’s 25-year milestone and Scouting. Transmissions are scheduled to begin Wednesday, November 12 around 1730 UTC and continue through Thursday, November 20 (time TBD). Downlink will occur on 145.800 MHz FM using the PD120 mode, following the standard ARISS pattern of approximately two minutes of transmission followed by two minutes off. A planned pause in images will occur to support an ARISS school contact with Azerbaijan on November 16 at 1450 UTC.
Radio amateurs and listeners worldwide are encouraged to participate, as ISS SSTV events are accessible to stations with a broad range of equipment. Many operators successfully receive images using only a handheld VHF radio and a phone-based decoding app, while more advanced satellite stations can produce particularly clean results. SSTV events continue to be a popular entry point for newcomers interested in amateur space communication.
Participants may upload their best received image to the ARISS SSTV portal at https://ariss-usa.org/ARISS_SSTV/ and then request a commemorative event certificate. Submitted images must be single, unedited SSTV frames in GIF, JPG, or PNG format, limited to 800×800 pixels and 800 kB. Once the image is uploaded, operators will be prompted to request their personalized certificate, and because submissions are only accepted for a short time after the conclusion of the event, prompt participation is encouraged.
In keeping with past ARISS activities, operators may also request a traditional ARISS QSL card to confirm SSTV reception. QSL requests must be mailed to the appropriate regional bureau with a self-addressed stamped envelope or sufficient return postage. Details and mailing addresses for each world region are available at https://www.ariss.org/qsl-cards.html, and operators should include date, time, frequency, and mode with their report.
Additional updates and operating details will be posted on www.ariss.org and ARISS social media channels as the event approaches. AMSAT congratulates ARISS and the ISS program on 25 years of continuous human presence aboard the station and encourages radio amateurs everywhere to join in this special commemorative SSTV celebration honoring the ISS legacy and the role of amateur radio in space education.
