In a large white multistory room, the main body of the Europa Clipper spacecraft rests upon a stand as it takes its position in the ultra-hygienic High Bay 1 in the JPL's Spacecraft Assembly Facility. The main body is composed of a shiny metallic cylinder with wiring and electronics attached to it. Two people in full white coveralls and masks crouch next to the main body. A person in full coveralls and a mask stands in the distance watching. On the right, two additional people in coveralls and masks watch the work being done on the mainbody of the spacecraft, with one pointing at the main body. In the distance, a the cleanrooms wall of fame is visible, with the identifiers of previous missions that have been assembled in the cleanroom.

The towering core of NASA’s Europa Clipper spacecraft is shown in the storied Spacecraft Assembly Facility at the agency’s Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) wide, the craft’s main body will be the focus of attention in the facility’s ultra-hygienic High Bay 1 as engineers and technicians assemble the spacecraft for its launch to Jupiter’s moon Europa in October 2024.

Europa Clipper will conduct nearly 50 flybys of Europa, which scientists are confident harbors an internal ocean containing twice as much water as Earth’s oceans combined. And the moon may currently have conditions suitable for supporting life. The spacecraft’s nine science instruments will gather data on the moon’s atmosphere, surface, and interior – information that scientists will use to gauge the depth and salinity of the ocean, the thickness of the ice crust, and potential plumes that may be venting subsurface water into space.
