  NASA Tracking and Data Relay Satellite; provided space-to-space relays, channelling high bandwidth data from spacecraft to the ground. TDRS 12 was the second replenishment satellite in the third generation of the TDRS system, using a high power version of the BSS-601HP satellite bus. By February 4 TDRS 12 was in a 35,780 x 35,795 km x 7.0 deg inclined geostationary orbit over 150.0 deg West.
