Something stinks in the space program.
Yesterday, one of two toilets at the international space station unleashed a foul stench after the pump separator flooded.
The multimillion-dollar, Russian-made toilet is shared by six space station residents and seven shuttle astronauts.
NASA flight director Brian Smith declined to comment on whether "overuse" was to blame for the toilet trouble.
Mission Control instructed the astronauts to place an "out of service" sign on the toilet as repairs are attempted.
Astronauts aboard the Endeavour space shuttle are now relying exclusively upon the on-board toilet, raising the possibility that the shuttle’s waste water tank could burst.
