An environmental control system includes an air conditioning subsystem; a mix manifold downstream of the air conditioning subsystem and upstream of an environment to be conditioned; and a contaminant removal subsystem downstream of the environment to be conditioned. The contaminant removal subsystem includes a first gas-liquid contactor-separator. The first gas-liquid contactor-separator includes a first packed, stationary bed that provides a heat/mass transfer surface for contact between a contaminated air from the environment and a liquid absorbent.

In accordance with at least one aspect of this disclosure, a life support system (LSS) for a spacecraft includes a gas accumulator configured to store a gas, the gas accumulator including a non-metallic inner lining. A fluid processor is fluidly connected to the gas accumulator configured to produce one or more life sustaining fluids from at least the gas. A supply conduit can be fluidly connected to the fluid processor configured to supply the one or more life sustaining fluids to one or more portions of the spacecraft.

A single-person spacecraft includes a pressurized crew enclosure, an external equipment bay, and an overhead crown assembly.

The present disclosure provides for ambient temperature catalyst compositions for trace contaminant control (e.g., for environmental control assemblies for space systems) and related methods of fabrication and use. More particularly, the present disclosure provides for ambient temperature catalytic oxidation (ATCO) catalyst compositions for trace contaminant control with improvements to carbon monoxide and hydrogen capture, and related methods of fabrication and use.

An article includes a closed-environment air purification system that has a purifier through which air can be recirculated. The purifier is capable at a temperature of equal or less than 35 C. of converting hydrogen in the air to water and converting carbon monoxide in the air to carbon dioxide. The purifier has a reactor bed that includes media comprised of support particles and a metal catalyst disposed on the support particles.

Clean condensate production may be produced from humidity in unfiltered air for an extended period of time using a membrane microgravity air conditioner which comprises an air box, comprising an inlet air flow path from a side face through an open top, and a filtering system disposed within the air box. The filtering system comprises one or more trash screens disposed in the inlet air flow path, one or more latent heat exchangers (LHX) disposed in the inlet air flow path, one or more particulate filters disposed in the inlet air flow path intermediate the trash screen and the LHX, one or more thermal control system (TCS) medium temperature loops, and one or more sensible heat exchangers (SHX) disposed in the inlet air flow path intermediate the particulate filter and the LHX.
