Advanced Space Suit Project (formerly Extravehicular Activity Suit/Portable Life Support System)

Project Introduction

The primary objective of the Advanced Space Suit project is to develop EVA Systems technology to enhance and enable efficient human exploration missions to any destination.  The project is focused on technologies for a new advanced Portable Life Support System (PLSS), Power and Avionics Systems, and Pressure Garment Systems (PGS) to support human exploration to asteroids, the Moon, and planetary bodies such as Mars and its moons.  The challenges of working in these exploration environments excee...

Technologies Within this Project

Technology Details: Advanced Space Suit (formerly Extravehicular Activity (EVA) Suit/Portable Life Support System (PLSS))

This technology is categorized as a hardware system for wearable applications

Description of technology:

The objective of this project is to mature technologies and systems that will enable future Extravehicular Activity (EVA) systems. Advanced EVA systems have applicability to all future human spaceflight missions. Advanced EVA systems have applications to current operations on the International Space Station (ISS), to extended operations on ISS past 2020, future missions to Low Earth Orbit (LEO) such as satellite servicing, missions beyond LEO such as exploration of asteroids, and surface explora...

Capabilities provided:

Suitport-compatible Advanced Extravehicular Mobility Unit (EMU) that enables EVA capability for any environment and mission architecture, with increased reliability, robustness, cycle life, comfort, and mobility; and reduced weight, power, and consumables usage.

Potential applications:

Advanced EVA systems have applicability to all future human spaceflight missions.  There are several components of the Advanced EVA Systems PLSS that could be considered for near-term integration into the existing EMU PLSS to support ISS operations through 2028, including the CO2 sensor development and the Suit Water Membrane Evaporator (SWME).  Additionally, the basic technology of the Rapid Cycle Amine (RCA) unit being designed for CO2 scrubbing in the suit ventilation loop is also being consi...
