As human exploration of space expands past low earth orbit and into cislunar space and beyond, NASA’s next generation Extra-Vehicular Activity (EVA) system will need technologies exceeding the performance of today’s ...

NASA seeks a validated, standardized methodology for measuring the inspired carbon dioxide gas (CO2) in Extravehicular Activity (EVA) and Launch, Entry, Abort (LEA) pressure suits to verify that ventilation designs maintain ...

The Z-2 space suit is the product of the last fifty years of NASA’s space suit research and testing experience. The suit was originally built as a prototype exploration space suit to evaluate advances in suit design and ...

Future exploration missions involving humans will be conducted in more challenging environments. Current Extravehicular Activity (EVA) gloves have limited life, severely limit hand mobility and are a significant source of ...

The NASA Extra-Vehicular Mobility Unit (EMU) has two methodologies for CO2 removal. The EMU Contamination Control Cartridge (CCC) containing LiOH has been largely phased out in favor of a regenerable silver-oxide system ...

This paper presents both near-term and long-term NASA Advanced Extravehicular Activity Pressure Garment development efforts. The near-term plan discusses the development of pressure garments components for the first design ...

Astronauts frequently suffer from orthostatic intolerance (OI) when returning to earth. Conventional wearable interventions for treating or preventing OI exhibit limited controllability (in elastic stockings) or limited ...

This paper explores the application of the inside access concept to rear-entry upper torsos for surface EVA. The concept allows one arm to retract inside the suit, for hand access to head and for other purposes. Throughout ...

Human missions to Mars may require radical changes in the approach to extra-vehicular (EVA) suit design. A major challenge is the balance of building a suit robust enough to complete multiple EVAs under intense ultraviolet ...

Over the past two years, the High Performance EVA Glove (HPEG) project under NASA’s Space Technology Mission Directorate (STMD) funded an effort to develop an electromechanically-assisted space suit glove. The project was ...
