Summary
WMAP launched on an United States Air Force Delta II 7425-10 from Space Launch Complex 17B, Cape Canaveral SFS, FL, USA on June 30, 2001. It was United States Air Force's 1,034th launch, 5th this year and humanity's 4,479th orbital launch attempt. It was the 1st Delta II 7425-10 flight. The payload was bound for Sun-Earth L2 (L2). WMAP, one of 2 catalogued objects, reached a 223 × 287,158 km orbit inclined 28.7°. 2 objects from this launch are catalogued, one of them a payload.
