ESO

Re-entered 14 Dec 1980

ESO (NORAD 12074, COSPAR 1980-067Y) was a SU satellite that re-entered Earth's atmosphere on 14 Dec 1980, launched on 31 Jul 1980 on the Romb mission. It was operated by PVO as part of the ESO programme. The spacecraft was built by YUZH on the ESO bus, with a mass of 5 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
