Re-entered 15 Oct 1973

DS-U2-IK No. 8 (Ion) (NORAD 6433, COSPAR 1973-022A) was a SU satellite that re-entered Earth's atmosphere on 15 Oct 1973, launched on 19 Apr 1973 on the DS-U2-IK Kopernik-500 mission. It was operated by IK as part of the DS-U2-IK programme. The spacecraft was built by YUZH on the DS-U2 bus, with a mass of 256 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
