The Planetary Plasma Environments group (PPE) has a strong heritage in the exploration of planetary magnetospheres and space plasma interactions throughout the solar system. It has contributed instruments to several past missions that flew-by or orbited Jupiter (Galileo, Cassini, Ulysses). The PPE participates in the JUICE mission by contributing hardware and scientific expertise to the Particle Environment Package (PEP).
The Sun’s planets and small objects have undergone substantial evolution. Deciphering the history of our cosmic home is not a simple task even though we now have access to a multitude of data gathered by space missions, remote observations, and laboratory studies of diverse samples. A significant fraction of materials available for the study of planetary bodies come from meteorites.
Data from NASA's Dawn mission, analyzed for the first time, suggest that brine rose from the depths and organic compounds were deposited in Urvara crater.
