The mass spectrometer will analyze gases in Europa’s faint atmosphere and possible plumes. It will study the chemistry of the moon’s suspected subsurface ocean, how ocean and surface exchange material, and how radiation alters compounds on the moon’s surface. Credit: NASA/SwRI

Two major pieces of flight hardware for the Europa Clipper spacecraft are attached to a flotron machine in a cleanroom. The hardware is visible in the rear middle of the images. The flotron is a large structure that allows the hardware to be rotated and moved for assembly purposes. The flight hardware consists of a large aluminum vault, which is shaped like a box. Within the vault, sensitive electronics will live, protecting them from radiation in Jupiter's environment. Attached the vault is a metal deck, called the nadir deck. Attached to this metal deck are multiple instrument sensors and cameras, which will allow the spacecraft to conduct science. Four engineers in full body coveralls and masks are seen working on flotron. An American flag is visible in the top left of the image.

The instrument sensor head is shown in the middle of the image as a large metallic device, gold in color, with wiring attached. The sensor is resting on a table in a cleanroom. There are no people visible in the image. Multi-layer insulation is visible on the top and underneath the instrument. On the side of the instrument is a panel with information etched in, including “SUDA SENSOR HEAD”, “LASP” (which refers to the Laboratory for Atmospheric and Space Physics), and the mascot symbol for the University of Boulder, which is a buffalo.
