NASA TO WEBCAST IBEX SPACECRAFT LAUNCH ON PEGASUS ROCKET OCT. 19
CAPE CANAVERAL, Fla. -- The first NASA spacecraft to image and map the
dynamic interactions taking place where the hot solar wind slams into
the cold expanse of space will be launched on Sunday, Oct. 19, at
1:48 p.m. EDT, during a launch window that extends from 1:44 p.m. to
1:52 p.m. The two-year mission will begin from the U.S. Army's Reagan
test site at Kwajalein Atoll, a part of the Marshall Islands in the
south Pacific Ocean.
Called the Interstellar Boundary Explorer, or IBEX, the spacecraft
will conduct extremely high-altitude orbits above Earth to
investigate and capture images of processes taking place at the
farthest reaches of the solar system. Known as the interstellar
boundary, this region marks where the solar system meets interstellar
space.
Carrying the IBEX spacecraft into orbit will be a Pegasus XL rocket
built by Orbital Sciences Corporation of Dulles, Va. The Pegasus will
be deployed from the Orbital Sciences L-1011 aircraft over the
Pacific Ocean about 125 miles north of Kwajalein. The spacecraft also
was built by Orbital Sciences.
Live coverage of the IBEX launch will be provided via the Web. No live
NASA Television coverage is planned. The live streaming video of the
countdown and launch will be available on the NASA home page at:
http://www.nasa.gov Audio coverage of the launch will be available at 321-867-1220, 1240,
1260, and 7135. Streaming video and audio coverage will begin at
12:15 p.m. on Oct. 19. It will conclude after spacecraft separation
from the Pegasus, approximately 12 minutes after launch.
