CANOGA PARK, Calif., Jan. 30, 2013 /PRNewswire/ -- Pratt & Whitney Rocketdyne
and RD AMROSS launched into the New Year today by successfully propelling
NASA's first, third-generation Tracking and Data Relay Satellite (TDRS-K) into
orbit. The mission launched from Cape Canaveral Air Force Station, Fla., by a
United Launch Alliance Atlas V rocket. The Atlas V is powered by the RD
AMROSS RD-180 booster engine and a Pratt & Whitney Rocketdyne RL10A-4-2
upper-stage engine. Pratt & Whitney Rocketdyne is a United Technologies Corp.
(NYSE: UTX) company. RD AMROSS LLC is a joint venture of Pratt & Whitney
Rocketdyne and NPO Energomash.

"The RL10 team is proud to start the New Year by helping NASA place a
satellite into orbit that will provide even greater capabilities to a network
that has been key to scientific discoveries here on Earth," said Christine
Cooley, RL10 program manager, Pratt & Whitney Rocketdyne.

"The RD-180 engine lifted the rocket off the pad with ease, once again proving
its ability to launch important payloads into space," said Bill Parsons,
president and CEO of RD AMROSS. "Congratulations to the entire RD-180 team
for another job well done."

TDRS-K is the latest addition to NASA's constellation of Tracking and Data
Relay Satellites. It is designed to relay communications from the
International Space Station, the Hubble Space Telescope and other satellites
in low-Earth orbit. The entire TDRS network allows information to move back
and forth between the orbiting spacecraft and ground controllers on Earth.

NASA started deployment of the TDRS network in 1983 with the maiden flight of
Space Shuttle Challenger. On its first mission, the satellite transmissions
enabled more shuttle data to flow to the ground than the previous seven
missions combined. NASA continued adding first-generation TDRS spacecraft
until 1995, and added three second-generation spacecraft from 2000 to 2002.
TDRS-K is the first satellite of the third generation, followed by TDRS-L
planned in 2014 and TDRS-M scheduled in 2015.
