The projects target is the creation of a lunar habitat that takes up a minimum of transport space while subsequently offering maximum interior volume – i.e. living space – for the occupants. By combine solid modular components with an inflatable shell structure, the usable inside volume is four times larger than of the transport volume. The habitat contain research areas, communal spaces, sleeping quarters, and an observation deck. Furthermore, psychological factors are also a consideration of major importance as the team members find themselves in an extreme living environment.
