Presented is a discussion of a new idea for a Europa sample return mission that is currently being developed at JPL as a Discovery proposal to NASA. Ejecta samples will be taken in a flyby of Europa, captured in aerogel and returned via a near free-return trajectory to direct reentry and parachute landing on Earth. Ejecta particles of the Europa surface will be created by striking the surface with a 10 kg impactor prior to a 50 km flyby. A mass spectrometer will analyze ejecta during the flyby as well as the atmosphere of Europa. Science, navigation requirements, ejecta modeling, and mission scenario will be discussed.
