Wide Field Infrared Explorer

(partly-failed 1999 infrared satellite)

Wide Field Infrared Explorer (WIRE) was a 1999 satellite intended to perform an infrared survey of the entire sky in the 21-27 micrometer and 9-15 micrometer bands. Equipment failure on launch partially ruined the instruments but it did have a life in photometric monitoring of bright stars for asteroseismology research. The satellite reentered the atmosphere in 2011.

Wide-field Infrared Survey Explorer (WISE) is a more recent mission with similar goals.
