The Wide Field Infrared Survey Explorer (WISE), which launched in December 2009, is a NASA Explorer mission that is currently producing an all-sky survey in the mid-infrared with far greater sensitivity and resolution than any previous IR survey mission. The survey has been highly successful, with millions of images collected, and nearly daily discoveries of previously unknown astronomical objects. The Utah State University Space Dynamics Laboratory designed, built, and characterized the science payload, which is a cryogenically cooled infrared telescope with four 1024x1024 infrared focal plane arrays covering from 2.8 to 26 µm. Pre-launch characterization included measuring focus, repeatability, response non-linearity, saturation, latency, absolute response, flat field, point response function, distortion, scanner linearity, and relative spectral responsivity. This paper will provide a brief overview of the payload, a discussion of pre-launch characterization methods, and a brief summary of present performance results from ground characterization and early on-orbit performance.
Funding for and management of this program was provided by the NASA Jet Propulsion Laboratory.
