The Europa Clipper team deploys a 28-foot (8.5-meter) boom that will support the spacecraft's magnetometer sensors. To fit aboard the rocket, the boom will be stowed in a canister. It will deploy to its full length in the days after launch. The magnetometer should allow scientists to confirm the existence of Europa’s ocean, and measure its depth and salinity. The instrument will also measure the ice shell’s thickness.
