 It could be possible to build a surface base that would produce fuel for further exploration of the Solar System . In 1997 , the Artemis Project designed a plan to colonize Europa . According to this plan , explorers would drill down into the Europan ice crust , entering the postulated subsurface ocean , where they would inhabit artificial air pockets .
