SBS-6
1990-091A
By the time SBS 6 reached the launch pad in 1990, the SBS Satellite Transponder Leasing Corp. operation had been sold to Hughes HCI and was later merged into the Galaxy system. It was launched together with Galaxy 6, two HCI satellites on the same Ariane rocket in an unprecedented risk for a commercial satellite operator.
The satellite, a spare for SBS 4 and SBS 5, was initially stationed at 99W. In 1997 the Galaxy system was merged with Panamsat; later Intelsat obtained the Panamsat satellites.

TDRS-7
1995-035B
TDRS G was carried into orbit aboard Discovery on the first flight with an uprated Block I SSME engine. It was deployed on the first day of the mission. TDRS G was the last of the IUS launched, TRW built satellites.
In May 1995, TDRS 1 was at 85E and being operated via the Canberra DSN station to provide service for GRO. It was due to be replaced by TDRS-3 and be sent to 139W for South Pole relay work. The prime spacecraft were TDRS WEST (TDRS 5) at 174 W and TDRS EAST (TDRS 4) at 41W. TDRS SPARE (TDRS 6) ws the on orbit reserve satellite at 46W. TDRS G was scheduled to go to 171W as a western spare.
