Unprecedented Starlink Reentries (spaceweatherarchive.com)
Feb. 5, 2025 (Spaceweather.com): What goes up, must come down–which could be a problem when you’re launching thousands of satellites. Since 2018, SpaceX has placed more than 7,000 Starlink satellites into Earth orbit, and now they are starting to come down. In January alone, more than 120 Starlinks deorbited, creating a shower of fireballs.

Hacking yourself a satellite – recovering BEESAT-1 [video] (media.ccc.de)
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.
