TITUSVILLE, Fla. - The Cryogenic Refuge Alternative Supply System, or CryoRASS, and a smaller liquid-air filled backpack called CryoBA, short for Cryogenic Breathing Apparatus, are on display at BCS Life Support in Titusville, Fla. The two systems are being developed by a NASA Kennedy Space Center engineering team in collaboration with The National Institute for Occupational Safety and Health to provide miners with twice the amount of breathable and cooler air than traditional compressed systems. The technology also could be used for commercial applications, such as fire and military rescue operations, as well as NASA's future human spaceflight missions.
