Mission Europa-Explorer

The German Research Center for Arti- ? cial Intelligence (DFKI GmbH) Robot- ics Innovation Center (RIC) launched the Europa-Explorer project in Decem- ber 2012 – a pilot survey for future mis- sions to Europa. It focuses on the aspect of navigation of robotic systems on and especially under Europa’s surface. Af- ter four years of concept development funded by the German Ministry of Eco- nomics (BMWI), a possible mission scenario has been drafted which covers all aspects of exploration, from the time $GYDQFHG&DSDFLWRUVIRU'HPDQGLQJ$SSOLFDWLRQV of landing until the transmission of data back to Earth.
