NEO Surveyor render
NEO Surveyor render An illustration of NASA's next-generation asteroid hunter, the Near-Earth Object Surveyor (NEO Surveyor), floats against an infrared starfield observation taken by NASA's Wide-field Infrared Survey Explorer (WISE) during its primary all-sky survey. The WISE starfield captured clusters of stars, clouds of gas and dust, and more than 100 asteroids seen as a series of red dots. NASA / JPL-Caltech / University of Arizona

NEO Surveyor will advance NASA's planetary defense efforts by finding, tracking, and characterizing potentially hazardous asteroids and comets that stray into Earth's orbital neighborhood.
