NEO Surveyor
NEO Surveyor is a NASA space telescope built to find large numbers of potentially hazardous asteroids and comets. It carries a single instrument, an infrared telescope with a 50 cm aperture and two heat-sensing infrared channels. Its goal is to find at least two-thirds of near-Earth objects larger than 140 m (460 ft).
