“…Investigation of previous evaluation methods identified that no comprehensive, expert approved list of quantifiable evaluation criteria capturing both engineering and human habitability concerns has been created 6,[13][14][15][16] . In particular, the desire to improve consideration of habitability issues into the layout evaluation is well documented 5,[16][17][18][19][20][21][22] . The development of a comprehensive set of automatically quantifiable evaluation criteria calculable from layout geometry and hardware functional characteristics is critical to ensuring high-quality habitat designs and speeding up the evaluation process.…”

“…The proposed evaluation criteria set is derived from existing quantitative and qualitative habitat and terrestrial architecture evaluation methods and human integration handbooks 1,6,14,15,19,[23][24][25][26] . In order to ensure a comprehensive set of criteria was chosen, a structured screening process was used to assess whether a criterion was essential to the assessment of interior layouts.…”

The objective of space habitat design is to minimize mass and system size while providing adequate space for all necessary equipment and a functional layout that supports crew health and productivity. Unfortunately, development and evaluation of interior layouts is often ignored during conceptual design because of the subjectivity and long times required using current evaluation methods (e.g., human-in-the-loop mockup tests and in-depth CAD evaluations). Early, more objective assessment could prevent expensive design changes that may increase vehicle mass and compromise functionality. This paper describes a new interior design evaluation method to enable early, structured consideration of habitat interior layouts. This interior layout evaluation method features a comprehensive list of quantifiable habitat layout evaluation criteria, automatic methods to measure these criteria from a geometry model, and application of systems engineering tools and numerical methods to construct a multi-objective value function measuring the overall habitat layout performance. In addition to a detailed description of this method, a C++/OpenGL software tool which has been developed to implement this method is also discussed. This tool leverages geometry modeling coupled with collision detection techniques to identify favorable layouts subject to multiple constraints and objectives (e.g., minimize mass, maximize contiguous habitable volume, maximize task performance, and minimize crew safety risks). Finally, a few habitat layout evaluation examples are described to demonstrate the effectiveness of this method and tool to influence habitat design.

“…Designing systems for use in space presents the unique challenge of coping with microgravity. One particular issue that arises in this environment is that of human postural stability (Cohen, 1990). While performing a task in microgravity, astronauts must be able to maintain their position and orientation, particularly for tasks involving high forces or precision work.…”

All authors contributed equallyThis study presents a human factors assessment of the foot restraint system used aboard the International Space Station. We examine pressure distribution maps of 3 different restraint materials (elastic strap; canvas strap; metal bar) at 2 incline angles (0 and 20 degrees plantar flexion) to explore potential system improvements. Our findings reveal that the canvas strap yields the most optimal combination of broadly distributed pressure while maintaining a high subjective evaluation of comfort and security. Foot restraint angle was found to be most critical for modulating pressure distribution in high-force conditions, suggesting that inclination improves security and decreases injury risk in high-force work areas.

“…To maximize the value of such a space station for this type of utilization, the main design driver, implemented from the earliest stages of the design process, should be the most efficient integration of the crew and the adaptation of the mission to the crew's needs and limitations [5]. Thus, it is advantageous to see humanrated space structures -be they orbital or planetary stations or crew compartments of interplanetary transfer vehicles -not as "machinery-with-attached-crew" like earlier spacecraft [7], but primarily as habitats. This puts the focus on designing space stations as habitats, not on designing habitats for space stations -under the assumption that increased habitability leads to increased crew productivity, and thus mission success.…”
