The Smithsonian Astrophysical Observatory's "Operation Moonwatch" spawned a culture of amateur skywatchers in the 1950s. we have a history of engaging "citizen scientists" to stimulate public participation in observing phenomena, conducting scientific research or collecting data. In that spirit, on June 18, 2013, we announced the Asteroid Grand Challenge to find all asteroid threats to human population and know what to do about them. We're seeking new ways to get the global public involved in protecting the planet from asteroid threats.

NASA's Near Earth Object Observation Program estimates that less than 10 percent of objects smaller than 300 meters in diameter and less than 1 percent of objects smaller than 100 meters in diameter have been discovered, and it will take a global effort with innovative solutions to accelerate the completion of the survey of potentially hazardous asteroids.
