The High Energy Transient Explorer. called HETE-2. is a small scientific satellite
that uses UV. X-ray and gamma ray instruments to detect and
localize gamma-ray bursts.
The coordinates of these bursts. called GRBs. are distributed to interested
ground-based observers within seconds of detection.
This allows detailed observations of the initial phases of GRBs. with the ultimate
goal of determining their origin and nature.
HETE-2 was successfully launched aboard a Pegasus rocket from Kwajalein Atoll.
in the Marshall Islands. on October 10. 2000. The spacecraft is still operational.
but instrument operations will be sporadic due to the advanced age of the batteries
on board.
