Re-entered 21 Feb 1975

DS-P1-Yu No. 74L (NORAD 7385, COSPAR 1974-058A) was a SU satellite that re-entered Earth's atmosphere on 21 Feb 1975, launched on 25 Jul 1974 on the DS-P1-Yu No. 74 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.
