Launch of Telstar: The First Active Communications Satellite
1962 · Cape Canaveral, United States
Telstar, the world's first active communications satellite, was launched, enabling the first live transatlantic television broadcast.
Telstar’s First Transatlantic Television Transmission
On July 9, 1962, NASA conducted a landmark test of the Telstar satellite, resulting in the first transatlantic television transmission. This historic event marked a significant milestone in communications technology and the growing capabilities of satellite broadcasts.
The Telstar Satellite
Telstar was a collaboration primarily between AT&T, Bell Telephone Laboratories, NASA, and international organizations including the British General Post Office and France’s National PTT (Postal, Telegraph and Telephone). The satellite was launched by NASA aboard a Delta rocket from Cape Canaveral, Florida, on July 10, 1962.
Transmission Details
The transmission originated from the ground facilities at the Andover Earth Station in Andover, Maine, and was received at the Pleumeur-Bodou station in Brittany, France. This successful transmission showcased the potential of satellites to relay television signals over vast distances, overcoming the limitations of ground-based transmission towers and cables.
Historical Significance
Telstar’s successful demonstration paved the way for global satellite communication, enabling live international broadcasts and revolutionizing how information and entertainment were shared around the world. It was the beginning of a new era in global communications, leading to subsequent developments in telecommunications and media.
