United Launch Alliance Successfully Launches WorldView-2 Mission for
DigitalGlobe & Boeing Launch Services

VANDENBERG AIR FORCE BASE, Calif., Oct. 8 /PRNewswire/ -- A Delta II rocket
successfully delivered DigitalGlobe's WorldView-2 commercial satellite into
orbit after launching the spacecraft from Space Launch Complex-2 at 11:51 a.m.
PDT here today. United Launch Alliance provided the launch services for this
mission on behalf of Boeing Launch Services. Delta II rockets previously
launched both the Quickbird-2 mission in October 2001 and the WorldView-1
mission in September 2007 for DigitalGlobe.

After a nominal approximately one-hour flight, the WorldView-2 spacecraft was
successfully deployed into its proper orbit. WorldView-2 was placed in a
sun-synchronous orbit where the spacecraft will perform its mission of
collecting high resolution commercial digital Earth imagery from space.

"Congratulations to both DigitalGlobe and Boeing Launch Services for this
tremendous launch success," said Jim Sponnick, ULA vice president, Delta
Product Line. "ULA appreciates the confidence that DigitalGlobe has shown in
our Delta team by launching WorldView-2 and two prior missions on Delta II
rockets. Delta II has achieved a launch success record of nearly 99 percent,
which is an incredible achievement and we are extremely proud to provide
reliable and cost-effective launch services for our customers."

This was ULA's seventh Delta II launch of 2009 and 12th overall launch of the
year. ULA began processing the Delta II launch vehicle in Decatur, Ala., two
years ago. Hundreds of ULA employees worked to prepare the vehicle for the
WorldView-2 mission.

For WorldView-2, the ULA Delta II 7920-10 configuration vehicle featured a
first stage booster powered by a Pratt & Whitney Rocketdyne RS-27A main engine
and nine Alliant Techsystems (ATK) strap-on solid rocket motors. An Aerojet
AJ10-118K engine powered the second stage. The payload was encased by a
10-foot-diameter payload fairing.

ULA's next launch, currently scheduled for Oct. 18, is the DMSP-18 satellite
for the U.S. Air Force aboard an Atlas V from Space Launch Complex-3 here.

Formed in 2006, ULA combines the successful Atlas and Delta expendable launch
vehicle programs, offering cost-effective and reliable launch services to U.S.
government customers, including the Department of Defense, NASA, the National
Reconnaissance Office and other commercial organizations.

ULA program management, engineering, test and mission support functions are
headquartered in Denver, Colo. Manufacturing, assembly and integration
operations are located at Decatur, Ala., Harlingen, Tex. and San Diego, Calif.
Launch operations are located at Cape Canaveral Air Force Station, Fla., and
Vandenberg Air Force Base, Calif.
