Laboratory Experiments for Future and Past Flight Missions 

Enceladus is known to eject material into space from a subsurface global salty water ocean. Therefore, the Cassini mission targeting the Enceladus plume could easily collect plume material in a flyby over the south polar terrain at a suitable altitude. Due to the big success of the Cassini space mission, follow up missions are planned for the future. Because much of the success in analyzing the space data came from laboratory experiments the current projects target at developing instruments for laboratory experiments, which on the one hand may have the potential to be even implemented on board of future space missions. On the other hand, the developed instruments will have the potential to support these missions through laboratory experiments that provide data for understanding particle interactions and atmospheric compositions of planets and their moons, as well as in the quest for searching life on planets and their moons in our solar system.
