TsM-e (NORAD 17845, COSPAR 1987-030A) was a SU satellite that re-entered Earth's atmosphere on 12 Apr 1987, launched on 31 Mar 1987 on the TsM-e 37Ke No. 010 mission. It was operated by NPOE as part of the TsM-e programme. The spacecraft was built by ZIKH on the Kvant bus, with a mass of 11,050 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
