NASA PREPARING OXYGEN GENERATION SYSTEM FOR SPACE STATION
Feb. 9, 2006
Katherine Trinidad Headquarters, Washington (202) 358-3749 Tracy Young Kennedy Space Center, Fla. (321) 867-2468 Steve Roy Marshall Space Flight Center, Huntsville, Ala. (256) 544-0034 RELEASE: 06-061 NASA PREPARING OXYGEN GENERATION SYSTEM FOR SPACE STATION NASA is preparing to launch an oxygen generation system to the International Space Station. The system uses water to generate breathable oxygen for crew members. Life support systems like this are necessary to support future long-duration missions to the moon, Mars and beyond. The system was shipped from NASA's Marshall Space Flight Center, Huntsville, Ala., on Jan. 24, and arrived the next day at the agency's Kennedy Space Center, Fla. The system will be installed in a pressurized cargo compartment later this month for a possible May launch aboard the Space Shuttle Discovery. "Delivering this hardware to the space station is a major step toward achieving the full potential of the complex," said Mike Suffredini, station program manager. "Once complete, the regenerative life support system will sustain additional crew members onboard that can conduct more scientific research. It also will give us experience operating and sustaining a 'closed-loop' life support system similar to that necessary for future human spaceflight missions farther from Earth," he added. 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. "Advancing life-support technology will become increasingly important as we pursue missions to the moon and Mars," said Bob Bagdigian, project manager at Marshall's Center for the Regenerative Environmental Control and Life Support System. The oxygen generation system is one of two primary components in the station's regenerative environmental control and life support system. The other component, the water recovery system, is planned for shipment to Kennedy early next year, once testing and design modifications are completed. The water system is designed to provide clean water by recycling wastewater and crew member urine. The recycled water must meet purity standards before it is used to support crew, payload and spacewalk activities. The recovery systems will be packaged into three refrigerator-sized racks for installation in the station's U.S. Destiny lab module. The station relies on a combination of expendable and limited regenerative life support technologies in Destiny and the Russian Zvezda service module. The advances made in the regenerative environmental control and life support system will help cut station operating costs. Less money will be needed to launch fresh supplies of air, water and expendable life support equipment to the station and return used equipment to Earth. The oxygen generation system was designed and tested by Marshall and Hamilton Sundstrand Space Systems International, Windsor Locks, Conn.

NASA is preparing to launch an oxygen generation system to the International Space Station. The system uses water to generate breathable oxygen for crew members. Life support systems like this are necessary to support future long-duration missions to the moon, Mars and beyond. Cool! I actually caught the brief blurb this evening on NASA-TV (via the net). /dps |

NASA PREPARING OXYGEN GENERATION SYSTEM FOR SPACE STATION
Good step. Didn't even realise that they would bother sending one to Destiny now, was expecting them to wait intl Node 3 (or whatever that module is to morph/ into/called.) When Elektron was first powered on, how long before it started to regularly have hiccups ? Didn't it have an initial honeymoon period without problems ? I.E. how long before any conclusions can be drawn on the US system being more reliable than Elektron ? If it works reliably, we have to wait until its first failures, or until it can show higher MTBF than Elektron at least for the "from brand new to first failure" portion. Unfortunatly, with only 2 crewmembers or possibly 3 if Shuttle becomes reliable, will they be able to give the US O2 generator a true test of reliability if they just use it in low power mode on and off as a supplement to Elektron (and for when elektron fails). |
