The Role of Light on Human Weil-Being During Settlement on Mars-A Design Analysis for the Lighting Strategy of MARSHA, Winner of NASA' 3-D Printed Habitat Challenge

摘要

This paper seeks to discuss the development and design considerations of the daylighting and electrical lighting strategy for MARSHA, the Martian habitat designed by our team, AI.SpaceFactory. It examines the design response to natural environmental factors on Mars, as well as the interior conditions of the designed habitat of MARSHA. In this context, we will be looking at the 24 h 40 min day/night cycle on the planet and how it may cause shifting and desynchronization of human biological (circadian) rhythms. Mars' distance and orbital path around the sun has a significant effect on the received natural light on the planet, further impacting the human experience. Additionally, the strong presence of radiation can isolate the crew in the interiors for long periods of time and reduce the ability to harvest daylight for daytime interior illumination. These factors increase human dependence on electrical lighting and advanced control systems that facilitate day to day tasks and entrainment of the biological rhythms, as well as support other human psychological and emotional needs. This project serves as a case study to contribute to the further development and understanding of lighting design strategies as they relate to human needs in extreme environmental conditions.
