A supporting frame for aerospace applications comprises a plurality of rods, which are arranged along two bases substantially parallel and opposite each other, and along two sides, which are substantially parallel and opposite to each other and are coupled to each other via the two bases; the rods are coupled to each other in a mutually rotating manner by nodes so as to be able to configure the supporting frame between a deployed operating condition and a compacted operating condition; the nodes are spaced apart from one another in the deployed operating condition and are each hinged to at least two of the rods; in the compacted operating condition, each of the nodes is placed side by side with two adjacent nodes so as to form, together, two supporting members arranged at opposite longitudinal ends of the supporting frame and each being ring-shaped.

A system includes an oxidative combustion reactor configured to receive solid organic waste and O2, and to output a combined stream of H2O and CO2. A separator is configured to receive the combined stream of H2O and CO2 from the combustion reactor and to separately output a stream of CO2 and a stream of H2O. A Sabatier reactor is operatively connected to receive CO2 from the separator and to receive H2 from an H2 source, and to output gaseous CH4.

In accordance with at least one aspect of this disclosure, a waste fluid water recovery system can include a waste fluid inlet line configured to connect to a waste fluid source, the waste fluid inlet line comprising one or more treatment components configured to treat the waste fluid, a treated waste fluid outlet line configured to connect to one or more outlets, a tank having a flexible membrane dividing an internal volume of the tank into a first portion and a second portion, a first line fluidly connected to the first portion of the tank, a second line fluidly connected to the second portion of the tank, and a switching valve connected between the first line, the second line, the waste fluid inlet line, and the treated waste fluid outlet line. The switching valve can be configured to connect the first line with the waste fluid inlet line and the second line with the treated waste fluid outlet line in a first state. The switching valve can be configured to connect the first line with the treated waste fluid outlet line and the second line with the waste fluid inlet line in a second state.

A laundry system can include an input shaft, an output actuator, and a motion converter connected between the input shaft and the output actuator. The motion converter can be configured to convert rotational motion of the input shaft to linear motion of the output actuator. The system can include a laundry agitation arrangement connected to the output actuator to be linearly actuated by the output actuator to agitate laundry.

A system to perform multi-stage cleaning of material from a space suit worn by an astronaut in a deep space environment includes one or more discharge units installed external to an interior volume of a facility in the deep space environment. Each of the one or more discharge units releases one or more substances. The one or more substances includes water or air and the interior volume of the facility is defined by an interior hatch that is separated from an exterior hatch leading to the deep space environment by an airlock. One or more collection units installed external to the interior volume. Each collection unit traps released material that is released from a space suit based on the multi-stage cleaning to prevent the released material from entering the interior volume.
