Olympus-1was acommunications satellitebuilt byAstrium(at the time of the construction of the satelliteBritish AerospaceandMatra Marconi Space) andThales Alenia Space(also at the time Alcatel Espace and Alenia Spazio), along withFokkerandSPAR Aerospace,for theEuropean Space Agency.At the time of its launch on 12 July 1989, it was the largest civilian telecommunications satellite ever built, and sometimes known as "LargeSat" or "L-Sat". The satellite had a series of unfortunate accidents in orbit and went out of service on 11/12 August 1993.[1]The first accident was the loss of ability to articulate the satellite's solar arrays. This was later followed by the loss of an on-board gyro during the height of thePerseidsmeteor shower. The satellite spun out of control and efforts to stabilise it resulted in the expenditure of the majority of its fuel. Subsequently, it was moved to a GEOdisposal orbitand was put out of commission.[2]The Olympus bus was reincarnated asAlphabus,made by the same manufacturers, this time forInmarsat(Inmarsat-4A F4).
