1993-003B
TDRS 6 (TDRS F) was aboard mission STS-54 on 1993 Jan 13. Deploy was at 2012, with IUS burns at approximately 2112 and 1993 Jan 14 0226. The burns lasted 2 min 26 s and 1 min 45 s respectively. TDRS 6 was moved to 150 W for a 90 day checkout period, and was then to be stations at 62W as an on-orbit spare. In fact, it was moved to 138W in mid-1993 briefly and then to 46W over the Atlantic from 1994 to 1999.
In 1996 TDRS 6 became Columbia Communications Corp's third C-band satellite, serving its AOR-II slot.
