New Hst Cryocooler May Get Other Roles
WASHINGTON Hubble Space Telescope engineers are spending this week activating an advanced mechanical refrigeration system that they expect will restore the telescope’s infrared vision, but without the vibration that could blur images of some of the most distant objects in the universe. If it succeeds in chilling IR detectors on the Near-Infrared Camera and MultiObject Spectrometer (Nicmos) to about 70K (-334F) without shaking the telescope, the experimental cryocooler could be the precursor to a new generation of mechanical cooling systems with applications on advanced scientific and military satellites.
