Re-entered 26 Aug 1966

E-6LF No. 101 (NORAD 2406, COSPAR 1966-078A) was a SU satellite that re-entered Earth's atmosphere on 26 Aug 1966, launched on 24 Aug 1966 on the E-6LF No. 101 mission. It was operated by IKI / BABTS as part of the E-6LF programme. The spacecraft was built by NPOL on the E-6 DU bus, with a mass of 1,328 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
