Title
Echo - A Passive Communications Satellite
Full Description
Echo, NASA's first communications satellite, was a passive
spacecraft based on a balloon design created by an engineer at
NASA's Langley Research Center. Made of Mylar, the satellite
measured 100 feet (30 meters) in diameter. Once in orbit,
residual air inside the balloon expanded, and the balloon began
its task of reflecting radio transmissions from one ground
station back to another. Echo 1 satellites, like this one,
generated a lot of interest because they could be seen with the
naked eye from the ground as they passed overhead.
