End of life

Out of service 30 Apr 1999
Cause The top stage fired the intended 3 times but did so much too early. The satellite separated 4 hours early, and this caused the spacecraft to remain in LEO.

The spacecraft was raised to a slightly higher orbit, using its onboard thrusters. Satellite controllers then turned off all functions, deliberately exhausted the on-board liquid fuel supply and drained all remaining electrical power from the spacecraft. The decision to raise the satellite to a terminal orbit was made after controllers exhausted all possible options to salvage it or raise it to a geostationary orbit.
