Engineers and technicians move the vault plate into position for installation on NASA's Europa Clipper spacecraft on May 3, 2024. The plate is made of tantalum metal that's about 1 millimeter thick, about 7 inches tall, and 11 inches wide (18 by 28 centimeters). It's part of the structure that will protect Europa Clipper’s electronics from Jupiter’s harmful radiation. The orbiter is being assembled in the clean room of High Bay 1 at the agency's Jet Propulsion Laboratory (JPL) in Southern California.
