The lunch of Telstar 1 enables television transmission to be sent back to earth by satellite and makes the world seem a little smaller.
Communication by space satellite, which has today become the basis of a thriving commercial industry and a vital factor in military operations, was first suggested by the writer Arthur C. Clarke in 1945. One of the first to carry to idea forward in the 1950s was a U.S engineer working for Bell Telephones, John R. Pierce, who played a leading part in the work that led to the lunch of the Echo Communications satellite in 1960 and Talstar 1 in 1962.
Echo reflected microwave radio signals back to Earth from its aluminum surface, but Telstar was a more sophisticated device, which for the first time allowed television transmissions to be winged back to Earth. It was launched by American Telephone and Telegraph in cahoots with Bell Telephones and the British and French post offices. a gigantic antenna, built in Maine, near andover, was locked on to the satellite, and subsequent televisions picture was relayed across the Atlantic to be received at stations in England and French.
The first picture from Telstar showed the flag at the Andover station, but it was presently transmitting a baseball game between the Chicago cubs and the Philadelphia Phillies, and President Kennedy used it to give a live transatlantic press conference. Telstar 1 went out in of action in February 1963, possibly affected by radiation from the testing of nuclear weapons. It was replaced by Telstar 2. Development continued, and in 1964 the syncom 3 satellite relayed pictures of the Tokyo Olympic Games across the pacific.
