As you've probably heard, there is a problem with the one (and only!) toilet on the International Space Station story here. Now don't get me wrong, I understand space is limited and weight is limited, but only one toilet? That seems dangerous to me (especially in zero gravity, where you can't expect Roto Rooter to make an emergency house call).
Anyways, there's only one, and it's not functioning properly. So we get this quote:
Nasa officials are considering having some parts flown to Cape Canaveral and placed in the shuttle during its countdownThere's the word "considering".
They are considering it. Some weak excuse about the current launch having a lot of weight on it. I would suggest that they find a few pounds to lose (even if ends up being a crew member).
