The first Telstar communications satellite is launched, the first attempt to forge a permanent trans-Atlantic telecommunications link with an satellite that both receives and actively retransmits signals. A multinational venture between communications companies and government agencies in America, England and France, Telstar relays the first live trans-Atlantic television broadcast, bringing together the three major American networks of the time and the BBC for a one-of-a-kind joint news broadcast. Live intercontinental telephone calls and other TV broadcasts are also handled by Telstar. Though it’s an experimental satellite, Tesltar is expected to remain in service for some time, but its operational life is reduced to less than a year by, among other things, the effects of high-altitude nuclear weapons tests. Telstar shuts down in February 1963, but remains in orbit to this day.
