The Jet Propulsion Laboratory (JPL) in Pasadena, California, was selected to host the Near-Earth Object program office because of its expertise in precision tracking of the positions and predicted paths of asteroids and comets. JPL is managed for NASA by the California Institute of Technology, and is the lead U.S. center for robotic exploration of the solar system. JPL spacecraft have visited all known planets.
