Hacking yourself a satellite - recovering BEESAT-1
In 2013, the satellite BEESAT-1 started returning invalid telemetry, rendering it effectively unusable. Because it is projected to remain in orbit for at least another 20 years, recovering the satellite and updating the flight software would enable new experiments on the existing hardware. However, in addition to no access to telemetry, the satellite also has no functional software update feature. This talk will tell the story of how by combining space and computer security mindsets, the fault was correctly diagnosed without telemetry, software update features were implemented without having them to begin with, and the satellite was recovered in September of 2024.
