Here is clear, concise alt text for this image:"Announcement graphic for an upcoming ARISS SSTV event featuring Series 30 images transmitted from the International Space Station. Images will be sent from the RS-38S module on 437.825 MHz using Robot 36 mode, starting the week of 1 December (exact date TBD). The event will include 12 images with transmissions lasting 36 seconds on, 2–3 minutes off. Thanks to Sergey RV3DR and ARISS-RU for organizing. Certificates will be available via the ARISS SSTV gallery on ariss-usa.org and will differ from earlier Series 30 awards. Includes ISS and ARISS logos and a photo of astronaut Frank Culbertson."

If you missed out on the chance to get the SSTV Series 30 images via the ISS, there's an event coming up to fulfill that need.

Satellite RS-38S will begin transmitting these images "within the next 5-7 days". Not all details are finalized, but what we know is below!
