'And the Laurel Goes to... the Spitzer Space Telescope'
February 24, 2004
Aviation Week & Space Technology magazine has honored the
teams that built NASA's new Spitzer Space Telescope with a
2003 Aerospace Laurel award. The awards, now in their 47th
year, recognize outstanding achievements in the global field
of aerospace.
Team members at NASA's Jet Propulsion Laboratory, Pasadena,
Calif., and Ball Aerospace & Technologies Corp., Boulder,
Colorado, won in the "Space" category for redesigning
Spitzer, which saved $800 million and provided a powerful
new instrument for studying the universe.
Formerly known as the Space Infrared Telescope Facility, the
Spitzer Space Telescope uses state-of-the-art infrared, or
"heat-sensing," detectors to peer into the farthest, darkest
and coolest reaches of space. To do this, it needs to stay
cool; heat emitted by the spacecraft can interfere with its
infrared detectors.
Engineers and scientists at JPL and Ball, building on an
idea by Spitzer team member Dr. Frank Low of the University
of Arizona, Tucson, solved this cooling problem with a
clever redesign of past telescopes housed in large "thermos
bottles." They shrank the thermos bottle to hold only the
science instruments and the coolant, and planned for the
first-ever Earth-trailing orbit, which takes Spitzer farther
away from Earth's warmth. This innovative "warm launch"
architecture allows the chilliness of space to do most of
the cooling.
Launched in August 2003, the Spitzer Space Telescope is the
fourth of NASA Great Observatories, a program that also
includes the Hubble Space Telescope, Chandra X-ray
Observatory and Compton Gamma Ray Observatory. JPL manages
the Spitzer mission for NASA's Office of Space Science,
Washington. Science operations are conducted at the Spitzer
Science Center at the California Institute of Technology in
Pasadena. JPL is a division of Caltech.
