Re-entered 2 Jul 1983

SO-M No. 509 (NORAD 14163, COSPAR 1983-067A) was a SU satellite that re-entered Earth's atmosphere on 2 Jul 1983, launched on 1 Jul 1983 on the SO-M No. 509 mission. It was operated by IKI / BABTS as part of the SO-M programme. The spacecraft was built by NPOL on the SO-M bus, with a mass of 1,060 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
