Image showing Southwest Research Institute (SwRI) Staff Engineer Yvette Tyler performs integration and testing on the electronics box for Europa Clipper’s mass spectrometer. 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

The SUDA sensor head is shown resting on a table in a clean room, seen on the right-hand side of the image. The sensor head is gold in color and looks slightly like a drum in shape. A clear tube is seen attached to the top, where nitrogen gas is pumped through. To the left of the sensor head, additional equipment is shown resting on the table. Above the table a fan device is shown hanging from the ceiling.
