Summary
RHESSI launched on an Orbital Sciences Corporation Pegasus XL from Cape Canaveral, Air launch to orbit on February 5, 2002 at 20:58 UTC. It was Orbital Sciences Corporation's 39th launch, 1st this year and humanity's 4,515th orbital launch attempt. It was the 16th Pegasus XL flight and the 1st this year. The payload was bound for low Earth orbit (LEO). RHESSI, one of 2 catalogued objects, reached a 595 × 616 km orbit inclined 38.0°. 2 objects from this launch are catalogued, one of them a payload.
