Associated space launch
Syncom 2 was the first geosynchronous satellite. Although the period was 24 hours and the spacecraft remained at a nearly constant longitude, the orbit was inclined at 33 degrees so it was not truly geostationary but moved in an elongated figure eight pattern 33 degrees north and south of the equator.
SYNCOM 2 (A 26) was lifted into orbit during the mission ‘Thor Delta B | Syncom 2’, on board a Thor Delta B space rocket.
The launch took place on July 26, 1963, 2:33 p.m. from Space Launch Complex 17A.
