Near-Earth Object Camera

NEOCam (the Near-Earth Object Camera) is a proposed space-based infrared telescope designed to survey the Solar System for potentially hazardous asteroids. Proposals for NEOCam were submitted in 2006, 2010, and 2015 to the NASA Discovery Program. In 2010, NEOCam was selected to receive technology development funding to design and test new detectors optimized for asteroid and comet detection and discovery. NEOCam would survey from the Earth–Sun L1 Lagrange point, allowing it to look close to the Sun and see objects inside Earth's orbit.
On 30 September 2015, NASA's Discovery Program selected NEOCam along with other four mission concepts for refinement during the next year. Each mission received $3 million for a one-year study. The winner will be chosen in September 2016, and must be ready to launch by the end of 2021. NEOCam would be the successor of NEOWISE mission. The principal investigator is Amy Mainzer of the NASA Jet Propulsion Laboratory (JPL).
==Overview==

The primary scientific goal of NEOCam is to discover and characterize the orbit of most of the potentially hazardous asteroids larger than 140 meters over the course of its 4-year mission. NEOCam's field of view is large enough to allow the mission to discover tens of thousands of new NEOs with sizes as small as in diameter.〔(【引用サイトリンク】title=NEOCam - Instrument )〕 Secondary science goals include detection and characterization of approximately one million asteroids in the asteroid belt and thousands of comets. In the event that a potential impactor is discovered, officials at NASA Headquarters will be immediately notified according to standard procedures already in place.
