ESO

Re-entered 10 Apr 1984

ESO (NORAD 14754, COSPAR 1983-091AB) was a SU satellite that re-entered Earth's atmosphere on 10 Apr 1984, launched on 31 Aug 1983 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.
