The SUDA sensor head rests upon a table in a clean room. The sensor head is gold in color, shaped slightly like a drum on its side with a door facing the viewer that is closed. An engineer in white coveralls, a mask, and light blue gloves is on the right side of the image and is seen peering over the instrument. The engineer is holding a handheld device attached a blue wire, which itself is attached to the sensor head, and they perform a test. Is a purple light is shown on the table and on the front of the engineer.

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
