Thor Delta B | Tiros 8

McDonnell Douglas | United States of America
Cape Canaveral SFS, FL, USA
Dec. 21, 1963, 9:30 a.m.

Thor Delta B | Syncom 2

McDonnell Douglas | United States of America
Cape Canaveral SFS, FL, USA
July 26, 1963, 2:33 p.m.
Status: Launch Successful
Mission:

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.
