Astra 1A
Astra 1A was the first satellite launched and operated by SES (Société Européenne des Satellites), launched in December 1988. During its early days, it was often referred to as the Astra Satellite, as SES only operated one satellite originally. The satellite provided 16 transponders(+6 as rescue) and television coverage to Western Europe from 1989 to 2004. Astra 1A was retired and became derelict in December 2004.
