Cleaners Quote by Mike Mullane
“There's no way you can use water to collect waste in zero gravity. So, basically, our toilet on shuttle operations is a vacuum cleaner. The urinal looks like a Shop-Vac hose. It has different-shaped fronts on it for males and females to use. The urine is sucked down that hose and goes into a tank.”
About This Quote
Source Interview: "Riding Rockets" by Mike Mullane, 2006
In microgravity, waste must be removed by suction because fluids don’t flow naturally; the shuttle’s toilet works like a vacuum.
In simple terms: Space toilets use suction to collect waste because there’s no gravity.

There was no CG involved, it was just painfully taking Collin [Farrell] and Jessica Biel and putting them upside-down, we built the set upside-down and just try to twist perspective to make it all seem like zero gravity.

![“In the space shuttle program, where we had males and females, I can tell you that nobody was doing that [sex] because there's absolutely no privacy.
