Europa Clipper's thermal imager

Caption

E-THEMIS lead scientist Philip Christensen stands next to the box-like "tent" that surrounds both E-THEMIS (left) and its optical test equipment. With the tent doors closed and sealed, the team can flood the tent with dry nitrogen gas to remove all water vapor inside. This lets engineers accurately test E-THEMIS' thermal sensitivity, which water vapor greatly interferes with.
