TDRS-B
TDRS-B was an American communications satellite, which was to have formed part of the Tracking and Data Relay Satellite System. It was destroyed when the disintegrated 73 seconds after launch. ==History== TDRS-B was launched in the payload bay of ''Challenger'', attached to an Inertial Upper Stage (IUS). It was to have been deployed from the Shuttle in low Earth orbit. The IUS would have then performed two burns to raise the satellite into a geosynchronous orbit. On the previous TDRS launch, TDRS-1, the IUS second-stage motor malfunctioned following the first-stage burn, resulting in a loss of control, and delivery of the satellite into an incorrect orbit.
