Satellite Designed for Launch Aboard Pegasus Rocket Into
150,000-Mile-Apogee Orbit; Combined Value for Satellite and Launch
Vehicle of Approximately $60 Million

Orbital Sciences Corporation (NYSE:ORB) announced today that the
National Aeronautics and Space Administration (NASA) has selected the
company's Interstellar Boundary Explorer (IBEX) satellite to carry out
the next mission in its Small Explorer (SMEX) series of scientific
spacecraft. Orbital is a key member of the IBEX mission team, which is
led by Principal Investigator Dr. A solid rocket motor, provided by Alliant
Techsystems (NYSE:ATK ), is used to boost IBEX into its highly
elliptical Earth orbit, with an apogee of approximately 150 ,000 miles
(or nearly two-thirds of the distance to the Moon). Together, the
satellite and launch vehicle contracts have an estimated combined
value of approximately $60 million.symmttm.

"Our team is delighted to be working with Orbital on IBEX," said
Dr. Orbital is also
building and launching the next SMEX mission, the Aeronomy of Ice in
the Mesosphere (AIM) satellite, scheduled for a September 2006 launch
aboard Pegasus. The CSAC development will produce miniature, low power atomic
clocks for precision timing applications in hand-held battery-powered
instrumentation for use by military personnel .

Orbital develops and manufactures small space systems for
military, commercial and civil government customers. Orbital also
offers space-related technical services to government agencies and
develops and builds satellite-based transportation management systems
for public transit agencies and private vehicle fleet operators. The size and power
reductions will be critical elements to moving portable precision timing into

The IBEX mission is scheduled for
launch in 2008 and will be designed for an in-orbit duration of at
least two years. They have
successfully met the DARPA milestones in Phase I and II and have now been
selected to carry the CSAC development to completion. However, the size and power
consumption of existing atomic clock technologies exceeds that of quartz-based
clocks by several hundred-fold, which has heretofore prevented the deployment
of atomic timing in portable applications. In Phase-III, Symmetricom
will further reduce the size and power by an additional tenfold.symmetricom.com
