NASA has approved the Near-Earth Object Surveyor space telescope (NEO Surveyor) to move to the next phase of mission development after a successful mission review, authorizing the mission to move forward into Preliminary Design (known as Key Decision Point-B). The infrared space telescope is designed to help advance NASA’s planetary defense efforts by expediting our ability to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit, collectively known as near-earth objects, or NEOs.
