Loral Skynet Marks 40th Anniversary of Telstar 1 - The World's First Active Communications Satellite.Business & Technology Editors Loral Skynet Loral Skynet is a full-service global satellite operator headquartered in Bedminster, New Jersey. The company provides a wide range of video and data transmission services. It became a subsidiary of Loral Space & Communications when Loral acquired it in 1997 from AT&T. today marked the 40th anniversary of the launch of Telstar 1, the world's first active communications satellite See: communications satellite. built by Skynet's predecessors at AT&T and Bell Laboratories. Telstar 1 was launched from Cape Canaveral Cape Canaveral (kənăv`ərəl), low, sandy promontory extending E into the Atlantic Ocean from a barrier island, E Fla., separated from Merritt Island by the Banana River, a lagoon; named (1963) Cape Kennedy in memory of President John aboard a Boeing Thor Delta rocket The Delta family of rockets is used in an expendable launch system that has provided space launch capability for the United States since 1960. Delta has a history of over 300 launches, with a 95% success rate. and soon thereafter broadcast the first live television signal from Andover, Maine Andover is a town in Oxford County, Maine, United States. The town was incorporate in 1804.[1] The population was 864 at the 2000 census. Andover is also home to the Andover Earth Station the location of the first live transatlantic television signal broadcast by to Goonhilly Downs, England and Pleumeur-Bodou, France. The transmission showed the American flag streaming over the Andover earth station Andover Earth Station is a satellite earth station located at (). The location was selected by AT&T in December 1960. The main factors were the topography of the land and the radio interference signal level. to the sounds of the "Star Spangled span·gle n. 1. A small, often circular piece of sparkling metal or plastic sewn especially on garments for decoration. 2. A small sparkling object, drop, or spot: spangles of sunlight. Banner." The same day, Telstar 1 carried the first long distance telephone call via satellite between AT&T's then chairman, Fred Kappel, and U.S. Vice President Lyndon B. Johnson. During its seven months in orbit, Telstar 1 dazzled the world with live images of baseball games, plays, musical performances, news broadcasts, scenes of the World's Fair in Seattle and a U.S. Presidential news conference. More than 200 million people watched as the United States and 16 European countries exchanged numerous live video signals of national monuments and famous images, including the United Nations building, Niagara Falls, the Eiffel Tower and the Statue of Liberty Statue of Liberty great symbolic structure in New York harbor. [Am. Hist.: Jameson, 284] See : America Statue of Liberty perhaps the most famous monument to independence. [Am. Hist.: Jameson, 284] See : Freedom . President Kennedy issued the following statement on the event's significance: "The successful firing and subsequent operation of the Telstar communications satellite is an outstanding example of the way in which government and business can cooperate in a most important field of human endeavor. The achievement of the communications satellite while only a prelude already throws open to us the vision of an era of international communications. There is no more important field at the present time than communications and we must grasp the advantages presented to us by the communications satellite to use this medium wisely and effectively to insure greater understanding among the peoples of the world." Telstar 1's technology differed from previous "passive" satellites - large reflective balloons that reflected radio signals - in that it received a signal from the ground, amplified it and sent it back to earth. The technology on Telstar 1 set the standard for all communication satellites that are in use today. Telstar 1 had the ability to transmit either one television channel or roughly 500 simultaneous telephone calls. One of today's most advanced communications satellites, by comparison, can carry more than 500 television channels and thousands of data circuits. An experimental satellite, Telstar 1 remained in orbit for seven months, ceasing transmissions in February 1963. Since 1962, Skynet has operated 14 satellites carrying the Telstar name. Skynet is currently constructing three new satellites - Telstar 8, Telstar 13 and Estrela do Sul 1 - that will carry on the Telstar heritage.

AT&T and Bell Labs began development of the Telstar satellite communications system in the fall of 1960. In April 1961, the AT&T and Bell Labs team joined with NASA NASA: see National Aeronautics and Space Administration. NASA in full National Aeronautics and Space Administration Independent U.S. , the British Post Office, and the French National PPT (Post Office), to continue joint work on the Telstar project.
