The Amateur Radio on the International Space Station (ARISS) program is planning a slow-scan television (SSTV) event starting on Thursday, July 20, and continuing for 2 days, to commemorate its 20th anniversary. Transmissions, set to get under way around 2125 UTC, will feature 12 images from past and present ARISS activities. The SSTV signal should be available nearly anywhere on the globe at some point during the event.
