ATK Technologies Support United Launch Alliance Atlas V Launch and LDCM
ATK Provides Critical Flight Precision Spacecraft Structures for Satellite
ARLINGTON, Va., Feb. 12, 2013
ARLINGTON, Va., Feb. 12, 2013 /PRNewswire/ -- ATK (NYSE: ATK) provided
critical hardware for both the United Launch Alliance Atlas V launch vehicle
and the Landsat Data Continuity Mission (LDCM) satellite that launched
February 11 from Vandenberg Air Force Base, Calif.
LDCM is a collaborative effort between NASA and the U.S. Geological Survey to
provide a long-term record of the Earth's landscapes for use in agriculture,
education, business, science and government. The data from the Landsat
spacecraft constitute the longest record of the Earth's continental surfaces
as seen from space.
"ATK is proud to provide key components of these important science missions
for NASA," said David Shanahan, Vice President and General Manager of ATK's
Space Components Division. "Landsat has provided remarkable data for nearly 40
years, and the work we collaborate on with our customers will lead to the next
generation's understanding of our planet."
For the LDCM satellite, ATK led the design, engineering, fabrication and
testing of the spacecraft's graphite composite structures from sites located
in San Diego, Calif., and Magna, Utah. Among the critical ATK-provided
structures are the Operational Land Imager (OLI) optical and intermediate
benches for Ball Aerospace in Boulder, Colo., and the spacecraft sensor
platform that supports both the OLI and Thermal Infrared Sensor (TIRS) for the
spacecraft integrator, Orbital Sciences Corporation in Gilbert, Ariz. The
precision optical structures met or exceeded requirements for thermal
distortion, pointing and stiffness while supporting the science sensors that
are vital for the spacecraft mission performance.
For the ULA Atlas V rocket, ATK produced the 10-foot diameter composite heat
shield, which provides essential protection for the first stage of the launch
vehicle, using advanced fiber placement manufacturing techniques at its Iuka,
Miss., and Clearfield, Utah, facilities. In addition, ATK manufactured the
Reaction Control System (RCS) propellant tank for the Atlas V rocket at its
Commerce, Calif., facility. The Atlas V rocket (AV-035) flew in the 401
vehicle configuration with a four-meter fairing, a single-engine Centaur upper
stage and no solid rocket boosters. This is the 36th ^ Atlas V launch using
ATK-built composite structures.
With the LDCM satellite, ATK is building on a strong heritage of providing
flight precision spacecraft structures for important NASA science missions.
Previously, ATK provided the structures for the bus core, solar arrays and the
photometer to Ball Aerospace for NASA's Kepler mission, which is searching for
habitable planets around other stars. The ATK Magna site is currently
providing the backplane, backplane support frame, Integrated Science
Instrument Module (ISIM) optical bench, secondary mirror struts and star
tracker structures for NASA's James Webb Space Telescope.
"We are very pleased to have the opportunity to support NASA's important
science missions," said Dave Howell, ATK's Operations director for Space
Components in Magna, Utah. "It is gratifying to know how important ATK's hard
work in engineering and manufacturing is to our nation's satellite programs."
TenCate Advanced Composites, based in Morgan Hill, Calif., and Hexcel
Corporation, based in West Valley City, Utah, provided advanced graphite
materials used by ATK in the manufacturing of the LDCM and JWST satellite's
graphite composite structures.
ATK is an aerospace, defense, and commercial products company with operations
in 21 states, Puerto Rico, and internationally. News and information can be
