Scientific paper

The Widefield Infrared Survey Explorer (WISE) is a NASA Medium Explorer (MIDEX) currently under construction which will survey the entire sky in 4 mid-infrared bands at 3.3, 4.7, 12 and 23 microns with vastly greater sensitivity than previous all-sky surveys at these wavelengths.
The WISE long wavelength channels will be very powerful for detecting Ultra-Luminous Infrared Galaxies, and WISE should detect the most luminous galaxies in the Universe. The WISE short wavelength channels will be very powerful for detecting old cold brown dwarfs, and WISE should detect the nearest brown dwarfs to the Sun. WISE will also measure the radiometric diameters of about 250,000 asteroids.
WISE will have a 40 cm cryogenic telescope, 1024x1024 arrays, a scan mirror to freeze images on the arrays while the spacecraft scans continuously, and will take 47'x47' images every 11 seconds in all four bands from an IRAS/COBE style Sun-synchronous nearly polar low Earth orbit. WISE is currently in Phase C/D. WISE is expected to launch in late 2009.
