coondoggie writes “NASA said its Wide-field Infrared Survey Explorer spacecraft successfully popped the cover off its infrared telescope and began “celestial treasure hunt” mission of sending back what will be millions of images of space. The WISE lens cap served as a safety system keeping the ultra-sensitive lens and telescope system safe until the spacecraft positioned itself correctly in orbit. The cap also served as the top to a Thermos-like bottle that chilled the instrument. WISE’s infrared telescope and detectors are kept chilled inside a Thermos-like tank of solid hydrogen, called a cryostat.”
