Wide-field Infrared Survey Explorer (WISE) is a NASA infrared-wavelength astronomical space telescope launched on December 14, 2009, and decommissioned/hibernated on February 17, 2011 when its transmitter was turned off.

WISE was an Earth-orbiting satellite with a 40 cm (16 in) diameter infrared telescope, which performed an all-sky astronomical survey with images in 3.4, 4.6, 12 and 22 μm wavelength range bands, over 10 months. The initial mission length was limited by its hydrogen coolant, but a secondary post-cryogenic mission continued for four more months.
