1. A modular, multi-crew life support system comprising:
a fan configured to draw in ambient air;
one or more assemblies that produce conditioned air from the ambient air, wherein each of the one or more assemblies is a rapid cycle amine (RCA) swing-bed assembly;
a housing configured to support an oxygen source;
a port configured as an inlet from the oxygen source to augment the conditioned air; and
a duct configured to disperse a result of augmenting the conditioned air as output air to support two or more occupants of an enclosure;
wherein the RCA bed is configured in two portions such that one of the two portions undergoes adsorption to remove carbon dioxide and water vapor from the ambient air while another of the two portions undergoes desorption for regeneration;
wherein the system further includes a vacuum line configured to expose the other of the two portions of the RCA bed to a deep space environment.
