A habitation module with a gravity chamber that provides an artificial gravity environment. In one embodiment, the gravity chamber is annular and includes an outer cylindrical wall, an inner cylindrical structure, and opposing side walls that connect the outer cylindrical wall and the inner cylindrical structure. The gravity chamber attaches to a cylindrical core member of the habitation module with support bearings. The support bearing includes an inner race attached to the cylindrical core member, and an outer race attached to the gravity chamber. A drive mechanism drives the outer race of the support bearing to rotate the gravity chamber about an axis to simulate a gravitational force within the gravity chamber.
