    The Advanced Crew Escape Space Suit System (ACES) provides a survivable environment for a crew member during launch and re-entry mission phases in nominal and emergency scenarios. The suit is a full pressure suit which delivers oxygen to the crewmember for breathing, suit pressurization, and anti-g suit inflation and is certified up to 100,000 feet in altitude. The suit system provides liquid cooling, emergency breathing, and escape hardware to aid survivability through bailout and land/water egress events.

    The suit system contains the following capabilities:

        • Full pressure suit (launch & reentry), gloves, boots, helmet
        • Provides 3.46 psi nominal operating pressure
        • Protection in low altitude bailout and ground egress scenarios
        • Ability to operate as open or closed-loop demand breathing system
        • Emergency breathing system
        • Liquid cooling system
        • Headset communication system
        • Search and Rescue identification and emergency communication hardware
        • High-altitude, automatic-inflation parachutes
        • Automatic-inflation life preserver
        • Survival drinking water packets

    Benefits of using the ACES

        • 30 years of flight-proven, existing technology.
        • Thousands of man-hours of operational and anomaly resolution experience among technicians, engineers, emergency personnel, and crewmembers.
        • Existing facilities, infrastructure, and GSE.
        • Early full operational capability flight readiness.
        • High confidence in technical feasibility.
        • Low risk posture given flight heritage.
        • Low cost.
        • Ability to upgrade from base ACES suit platform down the road.
        • Ability to focus resources on other technical challenges
