Summary
Relay 2 launched on an United States Air Force Thor Delta B from Space Launch Complex 17B, Cape Canaveral SFS, FL, USA on January 21, 1964. It was United States Air Force's 178th launch, 3rd this year and humanity's 296th orbital launch attempt. It was the 8th Thor Delta B flight and the 1st this year. The payload was bound for Elliptical Orbit (Elliptical). Relay 2, one of 2 catalogued objects, reached a 2,097 × 7,418 km orbit inclined 46.3°. 2 objects from this launch are catalogued, one of them a payload.
