The SUrface Dust Analyser (SUDA) is a time-of-flight mass spectrometer of reflectron-type that employs impact ionization and is optimised for a high mass resolution.[2][3] The instrument was selected in May 2015 to fly on board the Europa Clipper mission, that is planned for 2025[1] to Jupiter's moon Europa.
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.[4][5][6]
