Our pressure regulator allows, for the first time, continuous control of suit pressure, resulting in higher levels of flexibility and safety for extra-vehicular activity. Pre-breath protocols could be performed within the suit, decreasing preparation time & allowing for more rapid deployment. The suit will have flexibility to integrate across various spacecraft and missions of the future, regardless of cabin pressure. The regulator has been designed with safety first. It is robust and tolerant of contamination. It will withstand combustion events and retain enough capability after failure to return an astronaut back to the spacecraft safely.
