NASA Picks Contractor to Chill Space Telescope Instrument

NASA has awarded a subcontract to Northrop Grumman Space Technology in
Redondo Beach, Calif., to develop an ultra-cold mechanical helium
cryocooler for the Mid-Infrared Instrument on the James Webb Space
Telescope. The contract totals about $22 million.

NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. partner in
developing the instrument, along with a European consortium sponsored by
the European Space Agency. With a planned 2013 launch, the Webb Space
Telescope will study the earliest galaxies and some of the first stars
formed after the Big Bang. The cryocooler delivery date is 2010.

The Mid-Infrared Instrument must be cooled to 6 Kelvin (minus 449 degrees
Fahrenheit), much colder than the planned 40 Kelvin (minus 388 Fahrenheit)
temperature of the Webb Space Telescope. This will allow the instrument to
detect room temperature heat emitted by stars, galaxies and other objects.

Goddard Space Flight Center, Greenbelt, Md., manages the James Webb Space
Telescope for NASA. The California Institute of Technology in Pasadena
manages JPL for NASA.
