Europa Clipper’s Mass Spectrometer Delivered to JPL

Europa Clipper’s MAss Spectrometer for Planetary EXploration/Europa (MASPEX) is examined by workers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California. The Southwest Research Institute (SwRI) delivered the instrument to JPL in December 2022. MASPEX will analyze the gasses near Europa to understand the chemistry of Europa’s surface, atmosphere, and suspected subsurface ocean. It will also study how Jupiter’s radiation alters Europa’s surface compounds and how its icy surface and subsurface ocean exchange material.
