A 3D model of Jupiter's moon Europa, an icy moon with a hidden subsurface ocean.
Europa is the fourth largest of Jupiter’s 95 moons. It's the sixth-closest moon to the planet. Europa and Jupiter’s three other largest moons – Io, Ganymede, and Callisto – were the first moons discovered beyond Earth.
Earth’s first mission to conduct detailed reconnaissance of Jupiter’s moon, Europa. NASA’s Europa Clipper will determine if this ocean world has environments suitable for life to exist.

Overview. When Galileo Galilei discovered Europa and Jupiter’s three other large moons — Io, Ganymede and Callisto — more than 400 years ago, he revolutionized humanity’s view of the universe. The discovery disproved the common belief that Earth was the center of all motion in the heavens.
Jun 13, 2024 · Jupiter’s moon Europa is one of those places. It is a long way from the Sun—more than five times farther than the distance between Earth and the Sun. It is so cold on Europa that water on the surface of the moon is frozen as hard as rock. We can usually crack our Earth's winter ice with an ice pick.
NASA's Europa Clipper is launching Oct. 10, 2024, on the first mission to conduct a detailed science investigation of Europa. Six robotic spacecraft already have explored Europa, and scientists do regular checkups on the moon with the powerful Hubble Space Telescope. All Science Missions.
Europa is the sixth-largest moon in the solar system, slightly smaller than Earth’s moon. Scientists think a salty ocean lies below a miles-thick ice shell, sparking questions about potential conditions capable of supporting life underneath Europa’s surface.
