Overview: WISE is a NASA infrared-wavelength astronomical space telescope which was decommissioned in February  2011 when its transmitter was turned off. The Earth-orbiting satellite carried a 40 cm (16 in) diameter infrared telescope, which performed an all-sky astronomical survey with images in 3, 5, 12 and 22 μm wavelength range bands, over 10 months. The initial mission length was limited by its hydrogen coolant, but a secondary post-crygenic mission continued for four more months.
By October 2010, WISE hydrogen coolant and original NASA funding ran out, and the proposed WISE warm mission, using remaining functionality, was not approved by NASA. Rather than abandon the spacecraft, the NASA Planetary division stepped in with funding for a shorter fourth month mission extension called NEOWISE, to search for small solar system bodies close to Earth's orbit. In February 2011, NASA announced that NEOWISE had discovered many new objects in the Solar System, including 20 comets. The spacecraft was put into hibernation in February 2011.
In August 2013, WISE returned to service, for a three year stint, in an effort to identify the population of potentially hazardous near-Earth objects, as well as those suitable for asteroid exploration missions.
