NASA's Wide-field Infrared Survey Explorer, or WISE, spacecraft is situated on a work stand. At left on the spacecraft is the fixed panel solar array. In front, the square is the HGA Slotted Array (Ku-Band).
The Wide-field Infrared Survey Explorer mission will survey the entire sky in a portion of the electromagnetic spectrum called the mid-infrared with far greater sensitivity than any previous mission or program ever has.
The WISE telescope is an all aluminum optical system that will produce images of the sky with 2.75 arcsec resolution in four infrared spectral bands.
The WISE back-end imager optics. This picture shows the imager optics which are mounted at the back of the optical system.
