Re-entered 18 Aug 1971

Rotor No. 32L (NORAD 5379, COSPAR 1971-066A) was a SU satellite that re-entered Earth's atmosphere on 18 Aug 1971, launched on 5 Aug 1971 on the Zenit-4M mission. It was operated by GUKOSR as part of the Zenit-4M programme. The spacecraft was built by TSKBE3 on the Zenit-4M bus, with a mass of 2,200 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
