General Dynamics Provides Communications Link for Lunar Mapping Mission

FAIRFAX, Va., June 24 /PRNewswire-FirstCall/ -- General Dynamics Advanced
Information Systems is providing the communications link for NASA's Lunar
Reconnaissance Orbiter (LRO) mission launched on June 18, 2009. The mission
will use General Dynamics-made transceivers to communicate with ground control
as it maps and studies the lunar environment. General Dynamics Advanced
Information Systems is a business unit of General Dynamics (NYSE: GD).

LRO will fly to the moon atop an Atlas V rocket launched from Cape Canaveral,
Fla., and go into orbit, turning its suite of instruments towards the moon for
thorough studies. The spacecraft will also look for potential landing sites
for astronauts.

"The LRO mission continues General Dynamics' decades-long history of providing
communications links to space for many of NASA's most important missions,"
said Lou Von Thaer, president of General Dynamics Advanced Information
Systems. "Our transceivers will help ensure the success of the mission and
relay the critical spacecraft data that will help map the moon and identify
available resources."

The LRO mission will use General Dynamics' Advanced Multi-Mode Transceivers
that have been modified specifically for this mission. The transceivers will
send health and status updates and receive command instructions from NASA.
LRO will communicate at S-Band frequencies through the NASA Ground Network and
Deep Space Network.

General Dynamics has provided the critical communications link between Earth
and space since the mid-1950s. In all, General Dynamics has produced over 400
space transponders including over 150 Deep Space, Near Earth and Tracking and
Data Relay Satellite System (TDRSS) transponders and transceivers for NASA
missions. Examples include the Voyager spacecraft, launched in 1977, which
carries two Deep Space Transponders that are still functioning, and the two
first generation TDRSS user transponders flying on the Hubble Space Telescope
that continue to operate trouble free after more than 19 years of service in
space.
