A new conceptual design approach for habitative space modules

Existing Space modules were designed to meet the standards established by NASA, basically oriented to functionality. In future Space environments a high level of habitability in long duration missions will become a priority: besides comfort and ergonomics, these habitats will require the application of criteria to address human needs for living in confined environments. Once described the human stressors related to long-lasting isolation, the paper presents a habitative module designed to meet the needs related to privacy, comfort and orientation, with the aim of developing a first approach to a new conceptual comfort oriented design for Space habitats. Four different interior configurations of personal compartments have been analyzed to compose the contrasting requirements of comfort and space limits. With the pourpose of reducing the total length of the module, a structural design based on inflatable technology has been designed. Finally a color design approach has been introduced to make astronaut's orientation task easier inside the module. The approach moves a step forward in the direction of the integration between technical and environmental expertise to improve astronauts' comfort in Space environments. •A first approach to a new conceptual comfort oriented design for spatial habitat.•A habitation module that satisfies dimensional, comfort and psychological needs.•The use of inflatable structural system technology.•The color for space orientation within the module.
