Jupiter's moon Europa has a crust made up of blocks, which are thought to have broken apart and 'rafted' into new positions.

The propulsion module harness, installed onto a bake-out fixture, is rolled up to the propulsion module in preparation for transfer and installation. The harness is the cabling that connects all of...

All four of the reaction wheels installed onto NASA’s Europa Clipper are visible in this photo, which was shot from underneath the main body of the spacecraft while it was being assembled at the ag...

This view of Jupiter's moon Europa shows a portion of the surface that has been highly disrupted by fractures and ridges.

These images reveal the dramatic topography of Europa's icy crust.

Mihaela Ballarotto samples Europa Clipper's propulsion module for planetary protection cleanliness prior to harness installation. 

Could a liquid water ocean beneath the surface of Jupiter's moon Europa have the ingredients to support life? Here's how NASA's mission to Europa would find out.

This animation shows a 360 of NASA’s Europa Clipper spacecraft. 

Dark and splotchy-looking terrain is evidence of some of the most recent geologic activity on Europa.

Europa Clipper’s plasma instrument was tested in this calibration chamber at the Johns Hopkins Applied Physics Laboratory.

Backup flight-ready ion detectors for the SUrface Dust Analyzer (SUDA) are stored in a dry nitrogen environment to protect these highly sensitive instruments from degradation due to contamination o...

The imaging spectrometer's scanning mirror and data processing unit are carefully packaged into a specialized shipping container.

Jupiter's moon Europa, as seen in this image taken June 27, 1996 by NASA's Galileo spacecraft, displays features in some areas resembling ice floes seen in Earth's polar seas. 

An engineer prepares the ion detector for integration to the SUrface Dust Analyzer (SUDA) sensor head at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulde...

In this activity, students will build a spectrometer using basic materials to observe the light.
