The base of the main body of the Europa Clipper spacecraft is seen in the middle of the image. The main body is large, silver, and shaped like a cylinder, with wiring and electronics attached. Four people are visible surrounding the main body of the spacecraft, wearing full body coveralls and masks. The people are gently guiding the spacecraft into its stand where it will continue to be worked on in the Spacecraft Assembly Facility.

A worker kneels beside the Europa Clipper’s narrow-angle camera (NAC), which is on a metal platform with rods sticking straight up at the corners of the platform. The worker is covered head-to-toe in white protective clothing called a bunny suit. The worker is wearing a blue head covering, and a bright blue face mask. The NAC is wrapped in silver-colored insulating material, it has a round base about the size of tire. The lens is sticking out at an angle and is laced up inside the insulating material.
