ESO

Re-entered 22 Apr 1983

ESO (NORAD 13981, COSPAR 1982-076C) was a SU satellite that re-entered Earth's atmosphere on 22 Apr 1983, launched on 29 Jul 1982 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.
