Introduction The Spring 2021 Human Spaceflight Graduate Projects Team (CU SHEDS) has been tasked with designing a Deep Space Habitat (DSH). This project will be supporting Habitats Optimized for Missions of Exploration (HOME) Space Technology Research Institute (STRI) which is funded through NASA. The scope of the HOME Team’s research is focused on two overarching operational requirements of a deep space habitat: (1) Keep humans alive while they are resident, and (2) Keep the vehicle alive while they are not. The CU SHEDS team will design a deep space habitat that can be utilized for a variety of long-duration missions and meets these criteria. This will be achieved in part by designing the vehicle to be ‘self-aware’ and ‘self-sufficient’. In addition to designing this habitat, the CU sheds team will modify the mockup created by the Fall 2020 Graduate Projects team to serve as an airlock / robotics / logistics module of the DSH. Human factors testing will
