ESO

Re-entered 8 Jun 1984

ESO (NORAD 14597, COSPAR 1983-034E) was a SU satellite that re-entered Earth's atmosphere on 8 Jun 1984, launched on 19 Apr 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.
