Jupiter's moon Europa is smaller than Earth's moon yet may contain more than twice as much liquid water as all of Earth's oceans combined. Scientists believe that under its icy surface, Europa features a global saltwater ocean, perhaps 40 to 100 miles (60 to 150 kilometers) deep. Further inward, a rocky mantle and metallic core are likely. Europa's interior structure will be studied in detail by NASA's Europa Clipper spacecraft, which will orbit Jupiter and perform dozens of flybys of the moon.

Europa Clipper's three main science objectives are to determine the thickness of the moon's icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission's detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

Managed by Caltech in Pasadena, California, NASA's Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with APL for NASA's Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA's Goddard Space Flight Center in Greenbelt, Maryland, NASA's Marshall Space Flight Center in Huntsville, Alabama, and Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.

NASA's Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.
