Paper Abstract

The Wide-field Infrared Survey Explorer (WISE) is a medium class NASA Explorer mission designed to map the entire sky in 4 mid-infrared bands, with band centers at 3.4, 4.6, 12 & 22 μm. The sensitivity requirements are 120, 160, 850 & 4000 μJy in these bands. The angular resolution should be 6" FWHMor better except at 22 μm where diffraction in the 40 cm diameter aperture degrades the resolution to 12" FWHM. WISE takes images simultaneously in all 4 bands in a 47' FOV using 10242 pixel arrays and 2.75" pixels. WISE will be launched into a 500 km altitude 97° inclination Sun-synchronous orbit at the terminator. Launch is currently scheduled for 6 AM in late 2009. WISE scans a circle perpendicular to the Earth-Sun line which leads to an all-sky survey in 6 months.
