Telstar 1 is a defunct communications satellite launched by NASA on July 10, 1962. One of the earliest communications satellites, it was the first satellite to achieve live transmission of broadcast television images between the United States and Europe.
Subsequent Telstar satellites were advanced commercial geosynchronous spacecraft that share only their name with Telstar 1 and 2. The second wave of Telstar satellites launched with Telstar 301 in 1983, followed by Telstar 302 in 1984 (which was renamed Telstar 3C after it was carried into space by Shuttle mission STS-41-D), [21] and by Telstar 303 in 1985.
In the months that followed, these man-made radiation belts eventually caused six or more satellites to fail, [14] as radiation damaged their solar arrays or electronics, including the first commercial relay communication satellite, Telstar 1, as well as the United Kingdom's first satellite, Ariel 1.

The world's first passive communications satellite, Echo 1A, and first active communications satellite, Telstar 1, which enabled transatlantic television transmission, were launched by Thor-Deltas ...
It was built by AT&T in 1961 to communicate with the Telstar 1 satellite, the first direct relay communications satellite. It provided the first experimental satellite telephone and television service between North America and Europe. It was also used with the Relay satellite. The giant horn was dismantled in the mid-1980s along with the ...

Telstar 1 was capable of relaying television signals across the Atlantic Ocean, and was the first satellite to transmit live television, telephone, fax, and other data signals. [7] [8] Two years later, the Hughes Aircraft Company developed the Syncom 3 satellite, a geosynchronous communications satellite, leased to the Department of Defense.
