Re-entered 13 Oct 1970

DS-P1-Yu No. 38L (NORAD 4427, COSPAR 1970-051A) was a SU satellite that re-entered Earth's atmosphere on 13 Oct 1970, launched on 27 Jun 1970 on the DS-P1-Yu No. 38 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.
