Europa Clipper’s Vault Plate is Installed
The vault plate is shown held in place by several screws after its 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 outward-facing side of the vault plate is engraved with waveforms for the word “water” in 104 languages. The waveforms extend from a circular symbol in the middle of the design, which represents the non-spoken word for “water” in American Sign Language.
