How to design a space habitat that supports its residents' mental health
In extreme environments, habitats are built for survival. Submarines, Antarctic bases and post-disaster dwellings are designed to prioritize health and safety. This is especially the case for habitats in space, where room is limited, contact with Earth is remote and hazards are numerous.
Space habitats must incorporate design features that support residents' mental, emotional, and social well-being, according to researchers at MIT. Engineers are exploring ways to create environments that promote health and happiness, even as travel to the moon and Mars becomes a reality. Scientists have compiled a resource that links specific habitat design elements to behavioral health outcomes, which they have visualized in an interactive online platform.
Designing space habitats is crucial, as living in extreme environments is challenging. Lin, a Ph.D. candidate in Human Systems Lab and Engineering Systems Lab at MIT, explains that the team's work could be applied to other isolated and confined settings, such as submarines, polar expeditions, refugee camps, and war zones. The study, published in npj Microgravity, identifies key emotions and experiences that could be influenced by living in such environments and presents a new format for mapping risks associated with habitat design and its impact on mental, emotional, and social well-being.
The researchers mapped out a series of connections between habitat design factors and behavioral health outcomes, creating a DAG (directed acyclic graph) similar to the ones NASA uses to evaluate risks in spacecraft and habitats. The new format allows for the visualization of the relationships between design elements and factors like stress, anxiety, feelings of isolation, and other emotions that could impact crew members' well-being.
By incorporating this information into the design process, space habitats can be built to better support the mental health and overall health of their inhabitants.
