The Planetary Defense Coordination Office (PDCO) is a planetary defense entity established within the Planetary Sciences Division of NASA's Science Mission Directorate.1 Its goal is to search for and catalog near-Earth objects such as comets and asteroids, as well as potentially dangerous objects that could go on a collision course with Earth. In addition, this entity helps the United States government prepare for a potential impact event - and coordinate efforts to mitigate and deflect potential threats, if they are detected.

The Double Asteroid Redirection Test is a NASA space mission aimed at testing a method of planetary defense against near-Earth objects.
