WASHINGTON (AP) — The international space station's lone toilet is broken, leaving the crew with almost nowhere to go. So NASA may order an in-orbit plumbing service call when space shuttle Discovery visits next week.

Until then, the three-man crew will have to make do with a jury-rigged system when they need to urinate.

While one of the crew was using the Russian-made toilet last week, the toilet motor fan stopped working, according to NASA. Since then, the liquid waste-gathering part of the toilet has been working on-and-off. Fortunately, the solid waste collecting part is functioning normally.
