Re-entered 8 Dec 1977

GAMBIT-3 FM-49 (NORAD 10374, COSPAR 1977-094A) was a US satellite that re-entered Earth's atmosphere on 8 Dec 1977, launched on 23 Sep 1977 on the GAMBIT-3 Mission 4349 mission. It was operated by NRO / SAFSP as part of the KH8E programme. The spacecraft was built by LMSC on the KH-8 bus, with a mass of 2,400 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
