Abstract

This study was inspired by the idea of a Single-Person Spacecraft (SPS) proposed by the Genesis Engineering Solutions, Inc. The goal of the study is to investigate SPS applicability for diverse environmental conditions, identify critical functional requirements, and expand its capability. Achieving SPS commonality would allow additional mission flexibility facilitating future deep space explorations. The initial stage of the project was presented at ICES 2018 poster session and focused on: • Developing Functional Flow Block Diagrams (FFBDs) to define critical functional requirements • Conducting task analysis to identify critical and frequent activities of the operator • Performing simple anthropometric test to design human-centered cabin The anthropometric test provided baseline design considerations for Multi-Mission Single-Person Spacecraft (MMSPS) architecture advancement. This paper discusses next stages of the research. The methodology used in this work includes a study of shape influencing factors such as: • Gravity gradient affecting crew operations mobility and position inside the module during different stages of operations • Pressure vessel stress analysis • Mobility systems attachments and operations for in-flight and on-surface activities • Interior systems configurations and ease of maintenance operations The paper presents final design considerations of the vehicle for microgravity and partial gravity conditions, associated mobility systems, and its operational functionality using a gateway reference mission. The paper concludes with evaluation of the presented design based on operational efficiency, safety, and crew comfort (habitability) during EVA in orbit and on the surface of Mars or Moon.
