DS-P1-Yu No. 70L (NORAD 7611, COSPAR 1975-003A) was a SU satellite that re-entered Earth's atmosphere on 20 Nov 1975, launched on 21 Jan 1975 on the DS-P1-Yu No. 70 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.
