Summary
Rossi X-ray Timing Explorer launched on an United States Air Force Delta II 7920-10 from Space Launch Complex 17A, Cape Canaveral SFS, FL, USA on December 30, 1995. It was United States Air Force's 958th launch, 10th this year and humanity's 4,041st orbital launch attempt. It was the 2nd Delta II 7920-10 flight. The payload was bound for low Earth orbit (LEO). Rossi X-ray Timing Explorer, one of 5 catalogued objects, reached a 573 × 591 km orbit inclined 23.0°. 5 objects from this launch are catalogued, one of them a payload.
