  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, from where it was used to provide fixed satellite services, including broadcasting, audio and data transmission, to Asia and the Pacific Ocean.
  
  ## Westar 6
  
  As Westar 6, the satellite was built by Hughes Space and Communications. It was based on the HS-376 satellite bus. At launch it had a mass of 1,244 kg (2,743 lb), and a design life of thirteen years. It carried twenty four C-band transponders. After launch from the Space Shuttle as part of mission STS-41-B its PAM-D booster rocket misfired, and the satellite was stranded in a useless low orbit. It was retrieved by shuttle astronauts in November 1984, and Hughes was contracted to refurbish it. Westar 6 was eventually sold, for US$58 million, to the AsiaSat consortium and renamed AsiaSat 1.
  
  ## Re-Launch
  
  The launch of AsiaSat 1 was contracted to the China Great Wall Industry Corporation (CGWIC), and used a Long March 3 launch vehicle. The launch was conducted from Xichang Launch Area 3 (LA-3) at the Xichang Satellite Launch Centre at 13:30:02 UTC on 7 April 1990.
  
  ## Mission
  
  Asiasat 1 was replaced by AsiaSat 3S in May 1999. It remains in a graveyard orbit.
