AsiaSat 1 was a Hong Kong communications satellite, which was owned, and was operated, by the Hong Kong–based Asia Satellite Telecommunications Company. It was originally launched in February 1984 as Westar 6, but following a booster motor failure it was retrieved and returned to Earth in November of that year by Space Shuttle mission STS-51-A. After being sold to AsiaSat and refurbished, it was relaunched in April 1990, and positioned in geostationary orbit at a longitude of 100.5° East. It spent its operational life at 100.5° East,[1] from where it was used to provide fixed satellite services, including broadcasting, audio and data transmission, to Asia and the Pacific Ocean.[2]
