I was wondering if a geostationary satellite has ever broken up before. I found a NASA list of satellites that fragmented: History of On-orbit Satellite Fragmentations, 16th Edition https://ntrs.nasa.gov/api/citations/20220019160/downloads/HOOSF_16e_all_for_STRIVES.pdf https://ntrs.nasa.gov/api/citations/20220019160/downloads/HO... Searching that PDF for "geostationary" I found: "The Russian government’s disclosure of the Ekran 2 battery explosion on 25 June 1978 is the first known fragmentation in geostationary orbit." There are two other geostationary fragmentations in the list, Ekran 4 and Ekran 9. These two events are hypothesized to have also been due to battery explosions.
