The enormous spacecraft that will head to Jupiter’s moon Europa uses four large reaction wheels to help keep it oriented.

New research makes hypotheses that NASA’s Europa Clipper can test: Any plumes or volcanic activity at the Jovian moon’s surface are caused by shallow lakes in its icy crust.

The agency’s mission to explore Jupiter’s icy moon takes a big step forward as engineers deliver a major component of the spacecraft.

Parallel ice ridges, a common feature on Jupiter’s moon Europa, are also found on Greenland’s ice sheet.

Science instruments and other hardware for the spacecraft will come together in the mission’s final phase before a launch to Jupiter’s icy moon Europa in 2024.

Finding plumes at Europa is an exciting prospect, but scientists warn it’ll be tricky, even from up close.

Take a closer look at the complex choreography involved in building NASA’s Europa Clipper as the mission to explore Jupiter’s moon Europa approaches its 2024 launch date.

NASA has selected Space Exploration Technologies Corp. (SpaceX) of Hawthorne, California, to provide launch services for Earth’s first mission to conduct detailed investigations of Jupiter's moon Europa.

Jupiter’s moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore.

Jupiter’s moon Europa may have the potential to harbor life. The spacecraft will use multiple flybys of the moon to investigate the habitability of this ocean world.

Scientists have theorized on the origin of the water plumes possibly erupting from Jupiter's moon Europa. Recent research adds a new potential source to the mix.

The surface of Jupiter's moon Europa features a widely varied landscape, including ridges, bands, small rounded domes and disrupted spaces that geologists call "chaos terrain." Three newly reprocessed images, taken by NASA's Galileo spacecraft in the late 1990s, reveal details in diverse surface features on Europa.
