Boeing & SICSA DSG

This proposal for a Deep Space Gateway aims at combining excellence in engineering, mission planning and high-quality interior design to provide for a crew of four the best accommodation possible to work and experience life in micro-gravity far from the safety of Earth. Crew’s comfort and safety were the two most important criteria for the design of the mission and the spacecraft. Living and working in the orbit of the moon implies a consideration of worst-case scenarios that won’t rely on a quick return to earth as it is the case today on the ISS. Radiation exposure is increased, the need for a medical area and expertise is also required. All those elements as well as the psychological impact of being confined in a small environment will drive the design of the interior to be as compatible with the human psyche as possible. The implementation of bigger personal quarters as well as the presence of plants seemed to be two of the most important decisions. Consideration of the circadian rhythm will dictate how the light will be regulated as well as how the light will be propagated inside the habitat. A change of the interior arrangement of the DSG will also enable the crew to experience a variation of their working condition, driving up performances. A central axis about the size of the opening of the international port also drives the design as this axis needs to be free in case of contamination or failure of the structure of the modules, the circulation between the modules is extremely important, each one of them needs to be able to accommodate the four members of the crew for a period of at least 4 days, in case the integrity of Orion or a connected module is compromised.
