Pratt & Whitney Rocketdyne Helps Boost High Resolution Earth-Imaging Satellite

CANOGA PARK, Calif., Oct. 8 /PRNewswire-FirstCall/ -- Pratt & Whitney
Rocketdyne today helped boost a commercial Earth-imaging spacecraft into orbit
to more quickly deliver detailed images for map creation and in-depth
analysis. The satellite, WorldView-2, is the third in a constellation. Pratt
& Whitney Rocketdyne is a United Technologies Corp. (NYSE: UTX) company.

The mission used a United Launch Alliance Delta II rocket with a Pratt &
Whitney Rocketdyne RS-27A engine and launched from Vandenberg Air Force Base
in California. This marked the 232nd flight boosted by the RS-27 family of
engines.

"Once again, the RS-27A engine proved its success in boosting a payload into
orbit," said Elizabeth Jones, RS-27A program manager, Pratt & Whitney
Rocketdyne. "We're honored to help deliver technology that will dramatically
increase the speed and accuracy of satellite images for both the commercial
and government sectors."

WorldView-2 is the first commercial satellite to offer eight-band capability
with advanced accuracy, agility, capacity and spectral diversity. With an
altitude of about 450 miles, WorldView-2 each day will collect up to 376,000
square miles of imagery at a half-meter resolution. The satellite uses an
advanced gyroscope that allows rapid swings from one target to another,
allowing extensive imagery of many targets in a single orbital pass.
WorldView-2 alone can revisit any place on Earth in 1.1 days. As part of the
satellite constellation, revisit times drop below one day and never exceed two
days, providing the most same-day passes of any commercial high-resolution
satellite constellation.

Pratt & Whitney Rocketdyne, Inc., a part of Pratt & Whitney, is a preferred
provider of high-value propulsion, power, energy and innovative system
solutions used in a wide variety of government and commercial applications,
including the main engines for the space shuttle, Atlas and Delta launch
vehicles, missile defense systems and advanced hypersonic engines.
