SOLAR SYSTEM

Detailed explanation-1: -On July 10, 1962, Telstar 1 was launched from Cape Canaveral, Florida, the U.S. as the first commercial payload in space. Two days later, the world’s first active communications satellite transmitted the first global television signal.

Detailed explanation-2: -During the course of its operational lifespan, Telstar 1 facilitated over 400 telephone, telegraph, facsimile and television transmissions.

Detailed explanation-3: -Telstar operated successfully until February 1963, when it ceased to communicate, probably as a result of radiation from American nuclear-weapons testing in the atmosphere. Telstar 2, a heavier but basically similar satellite, was launched on May 7, 1963, into a higher orbit (apogee 10, 720 km [6, 700 miles]).

Detailed explanation-4: -Pierce’s team at Bell Labs also developed Telstar 1, the first active communications satellite capable of two-way communications. Telstar 1 was launched into low Earth orbit on July 10, 1962, by a Delta rocket. NASA provided the launch services and some tracking and telemetry support.

Detailed explanation-5: -In 1962, the communications satellite, Telstar, was launched. It was a medium earth orbit satellite designed to help facilitate high-speed telephone signals. Although it was the first practical way to transmit signals over the horizon, its major drawback was soon realised.
