Satellite proposals threaten the night sky In the United States, the Federal Communications Commission (FCC), the agency responsible for authorizing satellite launches and operations…

The FCC just opened public comments on SpaceX's plan to launch a million satellites to do AI compute in space. Under the current proposal, an environmental review won't be required. Please consider submitting a public comment to oppose this damaging plan.

Students had an SDR baseband analysis lab today where I told students to GTP their solutions using my baseline code and notes. One got a GMSK demod and decode working in 35 mins.

β€œa software issue will require the return of the rocket back to the processing building and the disassembly of the payload section. The potential need to ship the onboard avionics back to the manufacturer would likely push the mission well into 2026.”

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!
