50th anniversary marked of first TV satellite

Telstar -- built by Bell Telephone Laboratories for use by AT&T -- was the first privately sponsored space mission
A picture from Alcatel-Lucent shows technicians from Bell Labs mounting Telstar 1 to the top of the rocket that was to take it into space. Fifty years ago Thursday a beach ball-sized satellite carried the first television images across the Atlantic, kicking off a new era of global communications decades before the Internet.

Fifty years ago Thursday, a beach ball-sized satellite carried the first live television images across the Atlantic, kicking off a new era of global communications decades before the Internet.

The Telstar satellite -- built by Bell Telephone Laboratories for use by AT&T -- was also the first privately sponsored space mission, and was seen as part of the space race between the United States and the Soviet Union.

It was launched on July 10, 1962, and two days later beamed the first television satellite signal -- carrying images of the Statue of Liberty and the Eiffel Tower -- through bases in Andover, in the northeastern US state of Maine, and Pleumeur-Bodou in the Brittany region of France.

The 170-pound (77-kilogram) satellite flew at low orbit and the signal could only be picked up during the 20 minutes or so that it was overhead.

It carried part of a press conference by US president John F. Kennedy on July 23, 1962, in which he called the satellite "yet another indication of the extraordinary world in which we live."

"This satellite must be high enough to carry messages from both sides of the world, which is, of course, an essential requirement for peace," he said at the time.

A half century later, France's Ambassador in Washington Francois Delattre echoed Kennedy's sentiments, saying the Telstar pioneered technology that has made it possible for "any human being on earth to potentially communicate with any other wherever they may be."

Speaking via satellite at a joint US-French symposium in honor of the anniversary, the ambassador said this "helps to promote a better understanding between people."

Robert Tate, the US consul for western France, said that "keeping the lines of communication open and secure, supporting the freedom of expression whether in a town hall or in a chatroom... will be key as we endeavour and harness the acceleration of technological progress for a more prosperous and peaceful future."

However, reality has not always reflected the soaring rhetoric, and Telstar's onboard electronics failed a few months after it launched due to radiation from high-altitude US and Soviet nuclear testing.

The satellite carried over 400 telephone, telegraph, facsimile and television transmissions before its mission came to an end. The US Space Objects Registry says it remains in orbit.
