Summary
HETE-2 launched on an Orbital Sciences Corporation Pegasus Hybrid from Kwajalein Atoll, Air launch to orbit on October 9, 2000 at 05:38 UTC. It was Orbital Sciences Corporation's 37th launch, 5th this year and humanity's 4,430th orbital launch attempt. It was the 4th Pegasus Hybrid flight and the 1st this year. The payload was bound for low Earth orbit (LEO). HETE 2, one of 2 catalogued objects, reached a 603 × 643 km orbit inclined 2.0°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
The High Energy Transient Explorer 2 was a small MIT-led astronomy satellite that detected and rapidly localised gamma-ray bursts, distributing positions to ground observatories. It was air-launched near Kwajalein into a near-equatorial low Earth orbit.
