Abstract

For more than 60 years, the spacesuit has served as the single most critical, yet structurally constrained, element of human spaceflight. Its dual identity as both a protective exoskeleton and a life-sustaining pressure shell has shaped the design and performance of every extravehicular activity (EVA) system ever flown. As exploration shifts toward long-duration lunar and Martian missions, the limitations of these traditional “mobile pressure chambers” have become increasingly apparent, particularly in relation to mobility, metabolic cost, and environmental durability. This paper presents the historical evolution of gas-pressurized suits and the constraining biomechanical and material factors since the earliest EVA missions. It argues that persistent mobility limitations are not the result of isolated design flaws, but systemic consequences of gas-pressure mechanics. In response to these constraints, the paper positions mechanical counterpressure (MCP) as a viable and necessary alternative for next-generation EVA architecture. Rather than treating the spacesuit as a rigid enclosure, MCP reframes it as a responsive and human-centered performance system. This shift represents not merely an engineering improvement but a fundamental re-envisioning of how humans will move, work, and live in future planetary environments.
