The JEANNE Habitat Design for a 2033 Crewed Mars Mission

The recent advancement of government and commercial spaceflight programs have endowed the public with a re-newed excitement for the colonization of Mars. This paper proposes a concept for a sustainable Mars habitat architecture, the Joint Enhanced Architecture for Navigating New Environments (JEANNE). This architecture focuses on safety of the human crew through remotely operated construction, countermeasures against physical & psychological risks, and the Computerized Relationship Layout Planning (CORELAP) methodology for habitat layout. The main challenges considered include: radiation exposure, remote habitat construction, power generation, waste management, human physiology in 3/8's of Earth's gravity, and the behavioral and psychological performance of the crew on Mars, to name a few. The JEANNE Habitat aims to address the obstructions to human life on Mars using a hybrid of low- and high-Technology Readiness Level (TRL) technology, the Scalable Interactive Model of an Off-World Community (SIMOC), CORELAP, In-Situ-Resource-Utilization (ISRU), and overarching NASA standards and requirements. The scenario described in this paper is focused on a 500 to 600 day Mars surface mission in the Arcadia Planetia region with a four-person crew. Before the crew launches in 2033, there is a planned cargo launch in 2031. 3D models for each habitat module were designed and plugged into the SIMOC simulator. This C++ based simulation includes verification and testing of the design against the requirements that a user specifies. The primary points of interest in the simulation are on crew safety, ISRU, atmospheric management, water management, food production, and waste management. Results from the SIMOC simulation prove that the proposed design can support a crew of four inhabitants for the duration of the mission. The habitat status after 600 days yields the internal atmospheric composition of 19.2% oxygen and 0.05% carbon dioxide. For contingency scenarios, 1420 kg of potable water and 585 kg of food remain. The CORELAP algorithm defined several layout requirements, namely the bathroom must be kept far away from the food areas to prevent contamination while also being kept near the greenhouse. Also, the exercise room must be far away from work and sleeping areas due increased noise levels. Through design, analysis, and simulation, the JEANNE habitat is set to be ready for 2033 human surface missions, meeting NASA's Journey to Mars goal.
