1. An environmental control system for conditioning a cabin of a vehicle positioned in an enclosed air-evacuated environment, the environmental control system comprising:
at least one vessel containing a first source of a medium, wherein the at least one vessel is configured to be located on board a vehicle;
a first inlet for receiving the first source of the medium;
at least one inlet for receiving a second source of the medium, the second source of the medium including a first flow of the second source of the medium and a second flow of the second source of the medium, the at least one inlet including a second inlet associated with the first flow of the second source of the medium and a third inlet associated with the second flow of the second source of the medium;
a thermodynamic device fluidly coupled to the first inlet, the thermodynamic device including a compressor and at least one turbine operably coupled by a shaft, the first source of the medium being provided to the compressor and the at least one turbine in series;
a first mixing point fluidly coupled to the second inlet and an outlet of the at least one turbine; and
a regeneration heat exchanger fluidly coupled to another outlet of the thermodynamic device and to the at least one inlet for receiving the second source of the medium.
