Planetary Defense at NASA
In 2016, NASA established the Planetary Defense Coordination Office (PDCO) to manage the agency’s ongoing mission of finding, tracking, and better understanding asteroids and comets that could pose an impact hazard to Earth. Here you can stay informed about the PDCO, NASA’s Near-Earth Object (NEO)Â Observations Program, and upcoming planetary defense flight missions, including NASA’S NEO Surveyor mission.
