A habitation module that provides an artificial gravity environment. In one embodiment, the habitation module includes a rotating structure configured to rotate about an axis in relation to a stationary structure, and attachment assemblies configured to rotatably couple the rotating structure to the stationary structure. The attachment assemblies comprise bearings installed coaxially between a cylindrical housing of the rotating structure and a cylindrical body member of the stationary structure, and dynamic radial seals installed coaxially between the cylindrical housing and the cylindrical body member. The attachment assemblies further comprise a static seal assembly that includes an end cap movable between a locked position and an unlocked position.

A temperature control system may include a heat exchanger configured to cool air within a pressurized enclosed crew cabin when the air is circulated across the heat exchanger and coolant is circulated through the heat exchanger. The system may further include a sublimator configured to cool the coolant. The system may also include a primary coolant line configured to transport the coolant from the sublimator through the heat exchanger.

A water purification system comprises a bioreaction subsystem receiving contaminated input effluent and having a gas-lift anaerobic membrane bioreactor removing urea and organic matter to create a first effluent. A light-treatment subsystem receives the first effluent and exposes the first effluent to UV light to create a second effluent free from microorganisms. A reactor subsystem fluidically connects an ammonia-reducing reactor to the UV output and receives UV-treated second effluent and has a struvite regenerator connected to the ammonia-reducing reactor output, separating ammonia from the second effluent in the ammonia-reducing reactor, and outputting the ammonia. A separation subsystem fluidically connects to the reactor output and receives the second effluent substantially free from ammonia and has a continuous electro-deionization device separating brine/salts from the second effluent to produce potable water. A closed-loop includes an ammonia-converting subsystem and a sequential fertilizer producer.

A habitation module that provides an artificial gravity environment. In one embodiment, the habitation module includes a rotating structure that rotates about an axis in relation to a stationary structure. The rotating structure includes a first gravity chamber that projects radially from the rotating structure, and a second gravity chamber that projects radially from the rotating structure in an opposite direction than the first gravity chamber. The first gravity chamber and the second gravity chamber are each comprised of a plurality of ring members that form side walls of the first gravity chamber and the second gravity chamber. The ring members are concentric so that the side walls of the first gravity chamber and the second gravity chamber radially extend and radially contract in upon themselves.

A universal commode system (UCS) is provided and includes an air/liquid separator, a urine line connected to the air/liquid separator, a fan, a cabin air return line connected to the air/liquid separator and to the fan, a commode line connected to the cabin air return line, a first motor coupled to the air/liquid separator and configured to drive an operation of the air/liquid separator and a second motor independent of the first motor, coupled to the fan and configured to drive an operation of the fan.

Phase separator systems may include a condenser configured to receive humid air, the condenser configured to convert the humid air into a two-phase fluid having a gaseous portion and a liquid portion. A transition duct is arranged downstream from the condenser and configured to direct the two-phase fluid through a narrowing path defined by the transition duct. A separator is arranged downstream from the transition duct and configured to interact with the two-phase fluid that exits the transition duct and capture the liquid portion and permit the gaseous portion to bypass the separator and flow downstream therefrom as a reduced moisture content airflow. A condensate dispersion element is arranged between the condenser and the separator and includes a dispersion structure arranged to break up liquid droplets of the liquid portion of the two-phase fluid and direct said liquid droplets to the separator.

A habitation module that provides an artificial gravity environment. In one embodiment, the habitation module includes a stationary structure and a rotating structure. The stationary structure includes circular side walls that are coaxially aligned and attached by one or more support beams. The rotating structure slides onto the stationary structure, and rotates about an axis in relation to the stationary structure. The rotating structure includes a cylindrical hub, and a plurality of gravity chambers that are permanently affixed to the cylindrical hub and project radially from the axis. Radial seals form an air-tight seal between the rotating structure and the stationary structure.
