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.
