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.

2nd-gen Starlink satellites emit 30x more RF interference, blinding telescopes (astron.nl)
Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that the second generation ’V2-mini’ Starlink satellites emit up to 32 times brighter unintended radio waves than satellites from the previous generation, potentially blinding radio telescopes and crippling vital research of the Universe.
