Testy Toilet on Space Station

While the Crew Works to Fix Unit, 'Hold' Times Will Increase for Astronauts

One of the two bathrooms on the International Space Station is broken. Engineers at the Johnson Space Center are working around the clock to troubleshoot the problem, but it could take days to fix.

Astronaut Hal Getzelman radioed up the bad news to the crew on the space station. "When you get a second, if you could put an out-of-service note on the WHC [NASA's term for a toilet] and advise the crew members that station crew members will have to use the Russian toilet and shuttle crew members on the shuttle until further notice."

European Space Agency astronaut Frank De Winne is the guy tasked with putting his plumbing skills to work on short notice. He asked if engineers had an estimate on how long it might take to get the toilet back in operation.

"No, we don't have a good estimate," Getzelman said. "What happened, the pre-treat (chemical), we think, flooded the pump separator and we may have got some fluid where we didn't want it and it'll take us a while to work through a procedure to recover."

There are 13 people on the space station right now – a record. The crew represents the United States, Russia, Canada, Japan, and Europe. NASA has spent years getting ready for a crowd in space – adding additional sleeping quarters, learning how to recycle liquid waste into drinking water, and installing a second bathroom last year.

This mission, dubbed STS 127, is the first real test of those systems. Mission Control sent up a note to the crew on Sunday warning them to not overuse the new bathroom.

3. WHC USAGE TIME CONSTRAINTS With the high usage on WHC we would like to remind you about time constraints for WHC usage. These can be found on 2.301 WHC Cue Card under the block "WHC Time Constraints." - Recommend 6 min interval between use. - Three uses in a row (<6-min>

Translation: If someone uses the bathroom the next person to use it needs to wait six minutes, and if three people in a row use it six minutes apart it needs 30 minutes to recover.
