Image of the Telstar 1 satellite. Telstar was launched by NASA on July from Cape Canaveral, Fla., and was the first privately sponsored space-faring mission. Two days later, it relayed the world's first transatlantic television signal.
Here are several different sets of directions to make a scale model of NASA’s Hubble Space Telescope. These models aren’t working telescopes, but they can give students an up-close look at the telescope’s stru
Advances in electronics and rocketry led to the 10 July 1962 launch of Telstar, a spherical, cast-aluminium satellite with 72 solar panels on its surface. Designed and built to relay television programmes between the United States and Europe, Telstar transmitted pictures for the first time from New York to Pleumeur-Bodou on 11 July. It orbited at a low altitude (5,636 km) and could only make short transmissions (around 45 minutes).
