In this image, a Caucasian man wears a white, protective suit in a cleanroom.  His face is mostly covered and his hands are gloved.  He is working on the CRISM instrument for the Mars Reconnaissance Orbiter mission.  The instrument sits on a slanted aluminum-like board covered with yellow Kapton tape - a low-static tape safe for using in cleanrooms and near or on instrumentation.
