Re-entered 22 Feb 1999

Soyuz 7K-STM No. 78 (NORAD 25632, COSPAR 1999-007A) was a RU satellite that re-entered Earth's atmosphere on 22 Feb 1999, launched on 20 Feb 1999 on the Soyuz 7K-STM No. 78 mission. It was operated by RKKE as part of the 7K-STM programme. The spacecraft was built by PROGT 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.
