Re-entered 10 Nov 1968

DS-P1-Yu No. 13L (NORAD 3181, COSPAR 1968-028A) was a SU satellite that re-entered Earth's atmosphere on 10 Nov 1968, launched on 9 Apr 1968 on the DS-P1-Yu No. 13 mission. It was operated by PVO as part of the DS-P1-Yu B 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.
