Projects

WISE Icon WISE
Wide-field Infrared Survey Explorer (WISE) is a four-channel, super-cooled infrared telescope designed to survey the entire sky with 1,000 times more sensitivity than previous infrared missions.

NEOWISE Icon NEOWISE
The NEOWISE project is the asteroid-hunting portion of the Wide-field Infrared Survey Explorer (WISE) mission. NEOWISE harvests measurements of asteroids and comets from the WISE images and provides a rich archive for searching WISE data for solar...

NEOcam Icon NEOcam
The Near-Earth Object Camera (NEOCam) is a new mission proposal designed to discover and characterize most of the potentially hazardous asteroids that are near the Earth.
