The objective of the MEDUSA project is to test critical elements in the design and utilization of future inflatable habitats for the use on the Moon, Mars or in orbit.

The concept is to develop a fully submerged habitat segment in which elements such as internal living space, IVA, Life-Support-Systems and EVA preparation can be integrated and validated. The habitat is conceived as an inflatable structure and will also include an integrated greenhouse mock-up using algae and an exit port for access to an attached astronaut suit.

A proposed test-platform consists of an access port that would enable personnel to enter the inflatable structure.

The divers that test the habitat will work in a neutral buoyancy condition to simulate the reduced gravity for lunar or Martian scenarios or for the microgravity condition for an orbital application scenario.

The proposed project is a first step towards a proof-of-concept of several elements in the development of future inflatable habitats for space applications and could serve to validate IVA aspects in reduced gravity conditions.
