Westar 1Westar 1 was the first commercially-launched American geosynchronous communications satellite, launched by Western Union and NASA on April 13, 1974. It was built by Hughes for Western Union, using the HS-333 platform of spin-stabilized satellites. Westar 1 was the first of 5 Westar satellites launched by Western Union from 1974 to 1982. Westar 1, Westar 2, and Westar 3 were 12-transponder satellites while Westar 4 and Westar 5 were launched with 24-transponders. A sixth satellite, Westar 6 was launched but failed to reach orbit and was retrieved and later relaunched in orbit of Asia. Westar 1 was used by Western Union for their own communications, such as for sending telegrams and mailgrams to Western Union bureaus and US post offices respectively, as well as being utilized by outside customers such as PBS, who used it for sending television programming via satellite to their local affiliate stations throughout the 1970s and '80s.
