The SUrface Dust Analyzer (SUDA) is a time-of-flight mass spectrometer of reflectron-type that employs impact ionization and is optimised for a high mass resolution. The instrument was selected in May 2015 to fly on board the Europa Clipper mission which was sent to Jupiter's moon Europa in October, 2024.
This instrument will measure the composition of small, solid particles ejected from Europa, providing the opportunity to directly sample the surface and potential plumes on low-altitude flybys. Europa's internal liquid water ocean has been identified as one of the locations in the Solar System that may offer habitable environments to microbial extraterrestrial life.
