General Information:


The system uses water to generate breathable oxygen for crew members. The system will also help replace oxygen lost during experiments and airlock depressurization. Once activated, the oxygen generation system may daily provide up to 20 pounds of oxygen. During normal operations, it will provide 12 pounds daily; enough to support six crew members. The system will tap into the station's water supply and split the liquid into hydrogen and oxygen molecules. The hydrogen will be pushed into space, leaving the oxygen for the crew. The system is designed to operate with little monitoring.
