Now a Russian space official says that if the repair, scheduled for Wednesday, doesn't fix the situation, the space station's crew of three may have to come home early.
NASA said the main ISS toilet works for solid waste disposal but has an intermittent problem handling liquid waste. It's good for about three flushes and then requires some time-consuming maintenance and two pairs of hands before it will work again.
"It takes 10 minutes and two crew members," Shireman. "You can see how inconvenient that is."
The toilet on the International Space Station located in the Zvezda module uses a fan-driven suction system similar to the Space Shuttle WCS. Liquid waste is collected in 20 liter containers. Solid waste is collected in individual micro-perforated bags which are stored in an aluminum container. Full containers are transferred to Progress for disposal.
An additional Waste and Hygiene Compartment is scheduled be part of the Node 3 module to be launched in 2010. In 2007, NASA purchased a Russian-made toilet similar to the one already aboard ISS rather than develop one internally.
For urination (with the control panel switch set to #1) a replaceable funnel is used. The waste is sucked into a collection tank (there are ten in the module), and the air circulates through a charcoal filter before being sent back into the cabin. According to this post at CollectSPACE.com, “women use a sanitary-napkin-type pad which absorbs fluid”, which doesn’t sound too appealing! If the electric air pump fails, a device with a rubber-bulb hand pump serves as a backup.
For defecation (switch set to #2), a disposable bag is put into a container, which has an air suction tube connected to the container (the airflow goes through the bag and a charcoal filter). A carton cover needs to be removed from the bag before insertion; it contains some sanitizing chemicals and toilet paper (the latter is also removed). The user positions the device against their posterior. After finishing, a string around the edge of the bag snaps a rolled rubber cover into place, hermetically sealing the contents. After securely tying it with rubber ties (similar to the ones used to tie up the lining of the Sokol spacesuit), the bag insert is removed and put into another rubberized bag. This is placed into yet another bag, hermetically sealed and placed in a waste container with other rubbish (it will all burn up when the Orbital Module is discarded upon descent).

This is a perfectly good defecating thread and I look forward to his input.
