Launch Aboard Taurus Rocket Planned for Tomorrow From Vandenberg Air Force Base, California

Orbital Imaging Corporation’s
(ORBIMAGE) OrbView-4 imaging satellite is scheduled to be launched on Orbital
Sciences Corporation’s Taurus® rocket, on Friday, September 21,
2001. The available launch window extends from 11:49 a.m. to 12:07 p.m.
(Pacific), with a targeted launch time for the mission of 11:50 a.m.
This
schedule is subject to final preparations and testing, as well as acceptable
weather conditions at the Vandenberg Air Force Base, California launch site at
the time of the mission.

A live webcast of the launch will be available at http://www.orbimage.com
beginning at 11:30 a.m. Pacific (2:30 p.m. Eastern).

“The entire ORBIMAGE team, including our dedicated employees and loyal
partners, has contributed to this momentous milestone,” said Mr. Gilbert D.
Rye, ORBIMAGE’s Chief Executive Officer.
“The launch tomorrow is our biggest
single step to unveiling our worldwide high resolution and hyperspectral
imagery service.”

On launch day, the Taurus rocket will be prepared for its mission during a
four-hour countdown procedure.
Following a final launch decision, the vehicle
will ignite its first stage rocket motor, lift off and follow a pre-programmed
launch sequence controlled by its onboard flight computer.
Approximately 11
and a half minutes after liftoff, Taurus will deliver the OrbView-4 spacecraft
into a Sun-synchronous orbit approximately 470 kilometers above the Earth.

In addition, as a secondary payload the Taurus rocket will carry the
QuikTOMS ozone mapping satellite that is being launched for NASA’s Goddard
Space Flight Center.

About OrbView-4 Satellite Imagery:

OrbView-4 will be one of the world’s first commercial satellites to
provide high-resolution imagery from space.
OrbView-4’s high-resolution
camera will acquire one-meter resolution panchromatic (black and white) and
four-meter resolution multispectral (color) imagery. This imagery will be
valuable to customers around the world for a wide-range of commercial,
government and consumer applications.
With the ability to image virtually
anywhere in the world within three days, ORBIMAGE has established a global
distribution network to produce and deliver basic imagery as well as high-
resolution value-added products.

In addition, OrbView-4 will be the world’s first commercial satellite to
collect hyperspectral imagery.
Hyperspectral imagery will be useful for
classifying material types on the Earth’s surface, a capability that will be
beneficial in agricultural management, mineral exploration and environmental
monitoring.
