Re-entered 1 Apr 1974

DS-P1-Yu No. 59L (NORAD 6793, COSPAR 1973-057A) was a SU satellite that re-entered Earth's atmosphere on 1 Apr 1974, launched on 22 Aug 1973 on the DS-P1-Yu No. 59 mission. It was operated by PVO as part of the DS-P1-Yu A programme. The spacecraft was built by YUZH on the DS-P1 bus, with a mass of 200 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
