Habitability Study on Space Station Colour Design

Various stressors such as microgravity, vibration, radiation, restriction, and isolation in manned spaceflight environments can cause a variety of negative psycho-physiological effects. At the emotional level, for example, they may provoke anxiety and depression, which affects the astronauts’ operational efficiency and overall mission performance. The colour design of a spaceflight environment could positively affect a person’s emotional level and thus help to counteract such negative psycho-physiological effects. This paper presents a new model for validating the colour design of spaceflight environments at the psycho-physiological and emotional level in order to increase the quality of emotional habitability and support efficiency and performance. Psycho-physiological experiments were tested on six coloured light in a dedicate physical mockup of a specific spaceflight environment. In particular the sanitary area of the space station was used as a case study. As result the highest quality of emotional habitability was achieved in a yellow coloured light environment, that is very close to the natural solar condition. Note: In order to support the confidentiality in this paper is not mentioned the name of the space station.
