Near Earth Object Camera (NEOCam)
An Infrared Sensor Developed for NASA/JPL to Track Asteroids and Comets
The Near-Earth Object Camera (NEOCam) is a mission designed to discover and characterize most of the potentially hazardous asteroids that are near the Earth. NEOCam consists of an infrared telescope and a wide-field camera operating at thermal infrared wavelengths.

The NEOCam instrument will use detector arrays manufactured by Teledyne Imaging Sensors similar to those used by NASA's WISE mission and the Hubble Space Telescope's Wide-field Camera 3 instrument. The detectors are being modified slightly to allow them to detect longer infrared wavelengths while still being optimized for looking into cold space. The NEOCam detectors' high heritage for astronomical applications, excellent noise characteristics, and relatively "warm" allowable operating temperature make them the preferred choice for detecting near-Earth objects.

NEOCam will operate in a stable, cold environment. The mission's mercury-cadmium-telluride (HgCdTe) detectors are capable of operating in this environment for many years without requiring expensive cryocoolers or life-limiting cryogens. NEOCam will use Teledyne's HgCdTe Astronomical Wide Area Infrared Imager (HAWAII) detector architecture, which is in use in astronomical telescopes around the world.

NEOCam is managed by the Jet Propulsion Laboratory. NEOCam's partners include Teledyne Imaging Sensors, the Infrared Processing and Analysis Center (IPAC) of the California Institute of Technology, the Space Dynamics Laboratory, and Ball Aerospace.
