PlanetQuest is NASA's education and public outreach program centered on the science and technology of NASA's long-term search for habitable planets beyond the Solar System.

Major components of the PlanetQuest outreach program include:
 * PlanetQuest: the Search for Another Earth, a continuously updated public news and multimedia Internet site;
 * The Night Sky Network, a national coalition of amateur astronomy clubs who do astronomy education and public outreach on behalf of NASA;

Begun in January 2002 and based at NASA's Jet Propulsion Laboratory, PlanetQuest is funded by the Exoplanet Exploration Program, a long-term suite of NASA missions designed to detect and characterize of Earth-like planets. The main components of Navigator include two ground-based and two space based missions:
