Soyuz 7K-STM No. 61A

Re-entered 3 Aug 1990

Soyuz 7K-STM No. 61A (NORAD 20722, COSPAR 1990-067A) was a SU satellite that re-entered Earth's atmosphere on 3 Aug 1990, launched on 1 Aug 1990 on the Soyuz 7K-STM No. 61A mission. It was operated by NPOE as part of the 7K-STM programme. The spacecraft was built by NPOE on the 7K-STM bus, with a mass of 2,850 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
