How do astronauts go to the bathroom in space? Reprinted from The Conversation. Published March 23, Share This Print. A bathroom vacuum. After the deed is done. Please leave blank.

The bathroom works like a vacuum, with air flow moving your waste into a tank that gets changed every ten days.
If it gets too full, astronauts have to put on rubber gloves to push all of the waste further into the tank! Fun recycling fact — pee is collected and purified into drinking water. Astronauts have sleep pods that have sleeping bags that are tied to the wall so they can sleep without floating away!
The latex cuff was connected to a plastic tube, valve, clamp, and a collection bag. It wasn't a great system, and it sometimes leaked. Source: NASA. NASA even has a log of all the individual poops collected on the Apollo missions.
Skylab supported three crewed space missions in and ; the last and longest one was 84 days. After they relieved themselves, the men aboard Skylab had to vacuum-dry their feces with heat so that they could be dumped into the waste tank or studied. Their water came through a push-button shower head on a flexible hose, and drained into Skylab's vacuum system. The toilet system still wasn't that easy to use — the opening was less than 4 inches wide , about a quarter of the size of a regular toilet hole.
Astronauts had to be t oilet trained on Earth first, and some test runs even included a special under-the-seat camera so they could perfect their aim.
A separate funnel equipped with a fan suctions their pee away. But Whitson wants NASA to do better : " We want a closed loop system, which means we have to recycle all our water," she said. The brand name for the gear was Absorbancies, but the company that made them for NASA doesn't exist anymore.
NASA now has its own stockpile. As the Associated Press reported , the toilet breakdown was a problem, since it was the only one on the station at the time.
The system uses a little access port on the crotch of a spacesuit or garment, to which various bags or tubes could be attached to collect waste.
This invention could also help astronauts change their underwear without taking off a spacesuit. Thatcher Cardon worked nights and weekends on the prototypes with his wife and two teenage kids. I'd lay down and think and visualize different concepts," Cardon previously told Business Insider.
In the nearly 60 years since human beings first went to space, engineers have worked carefully on the technology inside spacesuits, shuttles, and capsules to accommodate this very earthly act, and the effort continues today: Astronauts are preparing to install a brand-new toilet on the International Space Station soon.
It is smaller and lighter than the old version. Read: A very relatable moment on the International Space Station. But the most important new feature is the one that allows astronauts to do something that the rest of us mostly take for granted on Earth. This matters more for the women in the astronaut corps, for whom the two bodily functions can be trickier to separate. With the older latrine models on the ISS, astronauts urinate into a handheld funnel and defecate into a device that looks like a smaller version of a traditional toilet seat.
A fan inside each apparatus suctions the waste away from the body, an important function in an environment where everything floats. Hold the funnel too close to the body, cutting off airflow, and liquid can end up pooling near the top. Lose contact with the seat, and waste might escape.
