While artificial gravity designs are not uncommon in spaceflight design proposals, few ever go beyond conceptual drawing stage from a mechanical and structural standpoint. This paper outlines the mass trades and analyses done to better refine a minimal-mass, single-launch capable system designed to integrate into as-built Mars mission architecture and which could be used to supplement the crewed periods with artificial gravity in an effort to minimize risks and increase crew comfort over the long mission durations required. While many previous designs focus on the benefits of a completed system and gloss over assembly and manufacturability questions, the authors of this paper have made a concerted effort to focus on real-world requirements and demands when running analyses – keeping cost, schedule, manufacturability, integration, launch vehicle lift mass, fairing dimensions, and safety all at the fore. This completed design has been created to be as modular as possible – capable of mating to a variety of stage and habitat designs and still providing this additional potential. Our results show that a system capable of spinning a crewed Mars Transit Habitat in the 45mt class, and a comparable transit stage, can be manufactured with a minimum factor of safety of 5, launched on a variety of commercial-launch vehicles, and integrated into the system with a minimal influence or impedance on the designs of either other component.
