Satellite Cooling System Breakthrough Developed by Lockheed Martin Space Systems
PALO ALTO, Calif., Dec. 4, 2013 - Scientists and engineers at the Lockheed
Martin Advanced Technology Center (ATC) have developed the lightest satellite
cryocooler, (cooling system) ever built. The breakthrough is seen as a
game-changer in the design of affordable, advanced-technology flight systems,
as it costs up to ten thousand dollars a pound for a satellite to orbit
Known as a microcryocooler, the new cooling system weighs approximately
11 ounces, three times lighter than its predecessor, and is expected to
have an operating life of at least ten years. The microcryocooler operates
like a refrigerator, drawing heat out of sensor systems and delivering
highly efficient cooling to small science satellites orbiting the Earth
and on missions to the outer planets.
"Temperatures as low as -320 F are required for infrared instruments and
the coolers must operate with minimum power and long lifetimes," said
Ted Nast, Lockheed Martin fellow at the ATC in Palo Alto. "That is why
we constantly pursue a deeper understanding of the dynamic effects of
temperature on cutting-edge technology and develop new systems, like our
microcryocooler, that will perform successfully within the demands and
constraints presented by severe, operational thermal environments."
Lockheed Martin is the industry leader in satellite cooling systems, having
successfully flown more than 25 cryocoolers in space over the past 40
years- most recently on the WISE and Gravity Probe-B NASA science satellites.
In addition to space applications, the microcryocooler can be utilized
in tactical systems, such as unmanned aerial vehicles and tanks.
Headquartered in Bethesda, Md., Lockheed Martin is a global security company
that employs about 116,000 people worldwide and is principally engaged
in the research, design, development, manufacture, integration and sustainment
of advanced technology systems, products and services. The Corporation's
2012 sales from continuing operations were $47.2 billion.
