Re-entered 7 Feb 1970

DS-P1-I No. 5L (NORAD 3846, COSPAR 1969-031A) was a SU satellite that re-entered Earth's atmosphere on 7 Feb 1970, launched on 28 Mar 1969 on the DS-P1-I No. 5 mission. It was operated by YUZH / 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.
