Abstract: NASA's Wide Field Infrared Survey Explorer (WISE), which launched in December 2009, is currently producing an allsky
survey in the mid-infrared (2.8 - 26 microns) with far greater sensitivity and resolution than any previous IR survey
mission. The ongoing on-orbit calibration of the instrument is performed at the Wise Science Data Center (WSDC), but
several of the calibration parameters of interest were best measured on the ground, and have been maintained as part of
the on-orbit calibration process.
The Utah State University Space Dynamics Laboratory (SDL) built the science payload, and performed a series of
ground characterization tests prior to launch. A challenge in a MIDEX mission such as WISE is to balance the various
program demands to perform a thorough ground calibration within schedule and budget constraints, while also
demonstrating compliance with formal flow-down requirements, and simultaneously verifying that performance has not
been degraded during late-program environmental testing. These activities are not always entirely compatible. This
paper presents an assessment of ground characterization challenges and solutions that contributed to a successful WISE
mission.

TL;DR: The Wide-field Infrared Survey Explorer (WISE) is a NASA Medium-Class Explorer (MIDEX) mission that has surveyed the entire sky in four bands from 3.4 to 22 microns with a sensitivity hundreds to hundreds of thousands times better than previous all-sky surveys at these wavelengths as mentioned in this paper.

Abstract: The Wide-field Infrared Survey Explorer (WISE), a NASA MIDEX mission, will survey the entire sky in four bands from 3.5 to 23 microns with a sensitivity 1000 times greater than the IRAS survey. The WISE survey will extend the Two Micron All Sky Survey into the thermal infrared and will provide the essential catalog for the James Webb Space Telescope. Using 10242 HgCdTe and Si:As arrays at 3.5, 4.6, 12 and 23 microns, WISE will find the most luminous galaxies in the universe, the closest stars to the Sun, and it will detect most of the main belt asteroids larger than 3 km. The single WISE instrument consists of a 40 cm diamond-turned aluminum three mirror anastigmatic telescope, a two-stage solid hydrogen cryostat, a scan mirror mechanism, and reimaging optics giving 5" resolution (full-width-half-maximum). The use of dichroics and beamsplitters allows four color images of a 47'x47' field of view to be taken every 8.8 seconds, synchronized with the orbital motion to provide total sky coverage with overlap between revolutions. WISE will be placed into a Sun-synchronous polar orbit on a Taurus 2210 launch vehicle. The WISE survey approach is simple and efficient. The three-axis-stabilized spacecraft rotates at a constant rate while the scan mirror freezes the telescope line of sight during each exposure. WISE has been selected by NASA to execute an extended Phase A study which will be completed in August, 2004. WISE is scheduled to launch in mid 2008.
