A: Typically, there are toilets similar in function to toilets on Earth, but they use air suction instead of water to make the waste go where they want it to, since there is no gravity. Solid wastes are compressed and stored on-board, and then removed after returning to Earth. Waste water is vented to space, although future systems may be able to recycle it.
There are many things we take for granted here on Earth that take on a whole new set of problems when you are in space orbiting the Earth. One of the most frequently asked questions that NASA receives involves bathroom rituals. Let’s see what a trip to the bathroom on orbit entails. Since astronauts are in a weightless environment, there is not enough gravity to hold a toilet bowl full of water in place or even keep the gross things that typically end up in a toilet from floating around. Because every thing floats, NASA had to develop a way to use air flow to make the urine or feces go where they wanted and not floating around in the space craft.
