(01/22/2002) - In the Vertical Processing Facility, STS-109 Payload Commander John Grunsfeld checks out the NICMOS radiator during crew familiarization activities. Part of the payload on mission STS-109, the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) is a new experimental cooling system consisting of a compressor and tiny turbines. With the experimental cryogenic system, NASA hopes to re-cool the infrared detectors to below -315 degrees F (-193 degrees Celsius). NICMOS II was previously tested aboard STS-95 in 1998. NICMOS could extend the life of the Hubble Space Telescope by several years. Astronauts aboard Columbia on mission STS-109 will be replacing the original NICMOS with the newer version. Launch of Columbia is scheduled Feb. 28, 2002
