Join team members from NASA’s Europa Clipper mission in a clean room at NASA’s Jet Propulsion Laboratory to learn about testing of the spacecraft’s magnetometer, which will help scientists answer the question, “Does Europa have an ocean?”

The magnetometer is made up of a long, 28-foot (6.5-meter) boom and three fluxgate sensors, which are compressed in a canister on the side of the spacecraft until the boom is deployed after launch. The electronics for the instrument are contained in the vault of the spacecraft, along with electronics for the other science instruments.

Spacecraft Makers is a video series that takes audiences behind the scenes to learn more about how space missions, like Europa Clipper, come together. Europa Clipper will explore this icy moon of Jupiter to see if there are conditions suitable for life.

Scientists have evidence that a global ocean lies under the moon’s surface, and the mission aims to confirm the existence of the ocean. The spacecraft needs to be hardy enough to survive a 1.6-billion-mile, six-year journey to Jupiter – and sophisticated enough to perform a detailed science investigation of Europa once it arrives at the Jupiter system in 2030.

Europa Clipper is expected to launch in October 2024 from Kennedy Space Center in Florida. For more information on the mission go to:
