Exoplanet Exploration Program

NASA's Exoplanet Exploration Program coordinates the search for and characterization of planetary systems beyond the Solar System. Its science goals are to measure how common different kinds of planets are, understand their diversity, and develop the capability to investigate nearby Earth-like worlds for habitable conditions and possible signs of life. The program combines space-mission science with enabling technology, ground-based observing support, community studies, and data resources including the NASA Exoplanet Archive. Successive investigations build the measurements and tools needed for increasingly detailed studies of other worlds.
