The interior is spread over four levels, each with its own function: garage, kitchen, sleep and recreation. All have their own window plus circadian lighting to maintain the body’s natural day and night rhythms.
The real pod will be 3-D printed on Mars using planet-based resources. In-situ construction is the only way to create space habitats – taking them from earth by rocket is not feasible.
