Re-entered 9 Jun 1988

Soyuz 7K-STM No. 55 (NORAD 19204, COSPAR 1988-048A) was a SU satellite that re-entered Earth's atmosphere on 9 Jun 1988, launched on 7 Jun 1988 on the Soyuz 7K-STM No. 55 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.
