Re-entered 21 Feb 1972

DS-P1-I No. 11L (NORAD 4847, COSPAR 1971-002A) was a SU satellite that re-entered Earth's atmosphere on 21 Feb 1972, launched on 14 Jan 1971 on the DS-P1-I No. 11 mission. It was operated by PVO as part of the DS-P1-I 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.
