The Syncom series of spacecraft (Syncom 1, 2, and 3), all launched during 1963, were the first attempts to test the idea of satellite communications from geostationary orbit.
As satellite communications evolved in the first years of the space age, geostationary orbits gradually emerged as the most effective approach to satellite communications. Spacecraft in this orbit matched the orbital rotation of the Earth and remained continuously over the same geographical area, making communication via satellite reliable and consistent.
Syncom 1 failed soon after launch, but Syncom 2 and 3 each operated for more than two years. In a historic first, Syncom 3 transmitted television signals of the 1964 Olympic games in Tokyo to the United States. Geostationary satellites still provide the bulk of space-based communcations today.
This full-size model of Syncom 1 was given to NASM in 1979.
