Intelsat 603
Intelsat 603 was launched by a Commercial Titan III on 14 March 1990. The separation of the upper (second) stage from the satellite failed. This left the satellite and the upper stage attached to each other, and Intelsat was unable to fire the perigee motor to boost the satellite to its higher orbit. Intelsat flight controllers jettisoned the perigee motor which detached the satellite from the Titan upper stage. However without the perigee motor the satellite could not be boosted to its nominal geostationary orbit. The on-board propulsion system was used to move the satellite into a slightly higher stable orbit.
Intelsat arranged for a rescue of 603 by the US Space Shuttle. STS-49 was launched on May 7, 1992, 7:40 p.m. EDT. Three of the shuttle astronauts successfully captured the satellite by hand on May 14, 1992, after several failed attempts using a capture bar. After being secured in the shuttle cargo bay, a new perigee kick motor was installed. Intelsat 603 was released from the shuttle and the perigee kick motor was successfully ignited and 603 was placed into the proper geostationary orbit.
