ESO

Re-entered 8 Nov 1988

ESO (NORAD 19545, COSPAR 1986-067AC) was a SU satellite that re-entered Earth's atmosphere on 8 Nov 1988, launched on 3 Sep 1986 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.
