Summary
Vela 5A & 5B launched on an United States Air Force Titan IIIC from Space Launch Complex 41, Cape Canaveral SFS, FL, USA on May 23, 1969. It was United States Air Force's 492nd launch, 18th this year and humanity's 972nd orbital launch attempt. It was the 13th Titan IIIC flight and the 2nd this year. The payload was bound for low Earth orbit (LEO). The tracked orbit of ERS 29, one of 7 catalogued objects, from June 19, 1969, was 59,663 × 69,122 km inclined 33.1°. 7 objects from this launch are catalogued, 5 of them payloads.
