AP reports that the only toilet on the international space station, which is now broken and in need of a new toilet pump, will receive a replacement part via emergency transport by the space shuttle Discovery.
from the article:
"While the three space station residents are eager to see the Kibo lab, the bathroom situation has become a more pressing issue. For the past week, the two Russian and one American men have had to periodically manually flush the urine side of the Russian-built toilet. The job takes 10 minutes and requires two people."

The solid-waste part of the toilet is working properly.
