NASA is developing the next generation of suit technologies that will enable deep-space exploration by incorporating advancements such as regenerable carbon dioxide removal systems and water evaporation systems that more efficiently provide crewmembers with core necessities such as breathing air and temperature regulation. Mobility and fit of a pressurized suit are extremely important in keeping astronauts productive, so NASA is focusing on spacesuit designs to help crews work more efficiently and safely during spacewalks.

The PXS suit is a technology demonstrator focused on improving suit fit and performance while minimizing the amount of equipment required for long-duration missions to low Earth orbit and beyond. The PXS incorporates sizing features that could one day be 3D printed on-orbit, in transit, or on Mars to achieve a customized fit for any crewmember, or change the orientation of bearings to optimize EVA mobility for different mission phases.

The Z2 suit is a technology demonstrator for a planetary surface suit; the suit is designed for maximum astronaut productivity on a planetary surface — exploring, collecting samples, and maneuvering in and out of habitats and rovers. The Z2 uses advanced composites to achieve a lightweight, high-durability suit that can withstand long-duration missions in the harsh environments found on Mars. Adjustable shoulder and waist sizing features maximize the range of crewmember sizes who can fit into any single suit.
