  • Notes

    • Telstar 1, primarily a communications satellite, was launched on July 10, 1962. On July 11, 1962, the Radome in Pleumeur-Bodou, France received the first transatlantic television signal from its sister station in Andover, Maine via the Telstar satellite launched the previous day. In the following six months, about 400 transmission sessions were conducted with multichannel telephone, telegraph, facsimile, and television signals. In addition, over 250 technical tests and measurements had been performed. Stations in the United States, Britain, and France participated in these activities. In November 1962, the command subsystem on the satellite failed. The cause was later established as degradation of transistors due to Van Allen belt radiation. Various operations effected a recovery that allowed the satellite to be used for another month and a half early in 1963, after which the command subsystem failed again. Telstar 2 was nearly identical to Telstar 1. The only significant design change was the use of radiation-resistant transistors in the command decoders. The Telstar 2 satellite orbit had a higher apogee than Telstar 1, which increased the time in view of the ground stations and decreased the time in the Van Allen belts. Telstar 2 was launched on May 7, 1963, and operated successfully for two years. - Suzanne
