NASA Advanced Space Suit Pressure Garment System Status and Development Priorities 2025

This paper discusses the current focus of NASA’s Advanced Space Suit Pressure Garment team’s efforts, the status of that work, and a summary of longer term technology development priorities and activities. This paper documents the various tests executed with the Exploration Extra-vehicular Mobility Unit (xEMU) over the past year. An overview of ongoing and planned xEMU testing and training is provided. The PGS team’s efforts in supporting the Exploration Extravehicular Activity Services (xEVAS) vendors is discussed. In addition, technology development efforts in coordination with the EVA and Human Surface Mobility Program (EHP) and the Small Business Innovation Research (SBIR) Program will be discussed in the context of supporting sustaining EVA operations on the Lunar surface over the coming decade, as well as Mars missions for the future. Finally, a brief review of longer-term pressure garment challenges and technology gaps will be presented to provide an understanding of the advanced pressure garment team’s technology investment priorities and needs.
