NASA Awards ILS and Atlas V Missions
NASA has chosen the Lockheed Martin
Atlas V rocket, offered by International Launch Services (ILS), to
launch the Pluto New Horizons mission in January 2006. The mission
as proposed is a scientific reconnaissance of Pluto and its moon,
Charon.
The selected vehicle is the Atlas V 551 configuration, with a
5-meter fairing and multiple solid rocket motors. This is the
most-powerful version of the Atlas rocket family, with a lift
capability ranging up to 19,100 pounds to geosynchronous orbit.
There have been three Atlas V missions since the rocket debuted
last August, with the most recent being the Rainbow 1 launch last
week, on an Atlas V 521 vehicle.
The space agency awarded the mission to ILS under the terms of
the NASA Launch Services contract signed in 2000. This agreement
was designed to be the primary way for NASA to procure launch
services on the highly reliable Atlas rocket through 2010. Atlas
vehicles have achieved the phenomenal record of 100 percent success
in 66 consecutive flights. NASA last year selected an Atlas vehicle
to launch the Mars Reconnaissance Orbiter in August 2005.
"We are thrilled that NASA chose the Atlas V vehicle
to launch the Pluto New Horizons mission," said ILS President Mark
Albrecht. "Such high-value scientific missions require the
time-critical and reliable access to space that Atlas has proven it
can deliver."
Albrecht noted that the Atlas V is the only American
medium-to-heavy-lift vehicle serving both the government and
commercial markets. "The award of the Pluto New Horizons mission
further solidifies the Atlas V business base with a mix of
government and commercial missions, demonstrating the continued
confidence in Atlas V by both communities," Albrecht said.
Since 1959, Atlas vehicles have flown 124 missions for NASA,
including the majority of all U.S. interplanetary spacecraft. Last
year, the Atlas IIA vehicle successfully lofted two Tracking and
Data Relay Satellites (TDRS) for NASA.
The launch services contract was awarded to Lockheed Martin
Commercial Launch Services, the contracting affiliate of
International Launch Services. ILS is a joint venture formed in
1995 to market the Lockheed Martin Atlas launch vehicle and the
Proton vehicle built by Khrunichev State Research and Production
Space Center of Russia.
The Atlas rockets and Centaur upper stages are built by Lockheed
Martin Space Systems Company at facilities in Denver (CO);
Harlingen (TX); and San Diego (CA). Atlas launch operations are
conducted at Cape Canaveral Air Force Station (FL), and Vandenberg
Air force Base (CA).
