Space Station Toilets Clogged
It's not easy finding a plumber in space
NASA is finding it is not just mechanical glitches that make the International Space Station a tough place to operate. Engineers are trouble-shooting a problem with the station's $250 million water recycling system, which processes urine into clean water for drinking, believe the cause is a high concentration of calcium in the astronauts' urine, which clogs the system.
Engineers at the Marshall Space Flight Center in Huntsville, Alabama, are hoping to come up with a fix in time to fly replacement parts out on the shuttle Endeavour, which is scheduled for launch on February 7 on a construction mission.
