ARISS has activated Slow Scan Television transmissions from the International Space Station for Series 32.
The SSTV event of ISS Expedition 74, Series 32, organized by ARISS, is part of an ongoing educational initiative that allows people around the world to receive images transmitted directly from the International Space Station using amateur radio. Running from May 8 at 10:30 UTC to May 12 at 16:40 UTC, the event features the theme “Cooperation in Space,” highlighting international collaboration in human spaceflight. During this period, the ISS transmits a series of SSTV images on 437.550 MHz in the 70 cm amateur radio band using the Robot 36 mode, where each image takes about 36 seconds to send, followed by short pauses of 3 minutes.
You can also receive some APRS packets on this frequency:

Hello,
Thank you for submitting your report.
The ARISS Series 31 images will consist in 12 pictures commemorating wants Cosmonauts Day, the 100th anniversary of liquid-fueled rockets, the inaugural Space Shuttle launch and SuitSat!
The certificate shows people associated with these events. From left: Konstanin Tsiolkovsky was a visionary and theoretician. He focused on the mathematical foundations of space flight, developed the rocket
formula (the Tsiolkovsky equation), and designed theoretical models of liquid-fuel rockets.
Robert Goddard – He was an engineer and practitioner. He focused on construction and testing. He launched the first liquid-fueled rocket in history in 1926.
The crew of the first space shuttle flight: John Young and Robert Crippen. The STS-1 mission aboard the Space Shuttle Columbia launched on April 12, 1981.
Exactly 20 years earlier, the first man in the world, Yuri Gagarin, made the first space journey on board the Vostok-1 spacecraft. 20 years have passed since another important event for radio amateurs.
SuitSat! (RadioSkaf) – a worn Russian Orlan spacesuit with an attached amateur radio transmitter. It was assembled by the crew of the Soyuz TMA-7 mission residing at the International Space Station. It was
launched into orbit on February 3, 2006, and operated for six months. It burned up in Earth’s atmosphere on September 7, 2006.
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). The
primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and
amateur radio.
From April 10 (12:00 UTC) to April 14 (11:59 UTC), 2026, SAKHACUBE-CHOLBON (RS18S) CubeSat will be transmitting images via SSTV mode. The event commemorates the International Day of Human Space Flight on April 12.

The signal from Ten-Koh2 is weaker than expected.
At our ground station, we are monitoring telemetry(voltage, temperature etc.) via the CW beacon. Reception reports via SatNOGS are very helpful. We would appreciate your continued support in receiving signals.
Currently, only the CW signal on 435.860 MHz is active. It is transmitted every 90 or 180 seconds depending on the satellite status.
Thank you very much for your cooperation!!
