We are living in an era where interplanetary travel, most significantly to Mars, is widely discussed in both science and popular culture. However, considerably less attention is placed on the quality of living spaces provided for the mission crew even though it will have significant impacts on both the design of the journey and the overall success of the mission. That is why our project of a Martian habitat firstly seeks to identify the crucial technical and human-centered architectural challenges of a long-duration stay in seclusion and confinement in the hostile Martian environment. Secondly, through systematic analyses and case studies it investigates necessary theory to tackle these challenges and, lastly, through integrated interdisciplinary design, it seeks to translate the gathered theory into a comprehensive design for a permanent Martian habitat that will support the physiological and psychological well-being of the six-member crew.
