How do astronauts go to the bathroom in space? – Henry D., age seven, Cambridge, Massachusetts
Whether you employ a pigsty in the basis or a fancy gilt-plated toilet, on Earth, gravity pulls your waste matter downward and away from y'all. For astronauts, "doing their duty" is a bit more complicated. Without gravity, whatsoever loose drops or dribbles could float out of the toilet. That's non good for astronauts' health, nor for the sensitive equipment inside the space station.
I study volcanoes on other planets, and I'yard interested in how people tin work in farthermost environments like infinite.
So how do you get to the bath in infinite or on the International Space Station? Carefully – and with suction.
A bathroom vacuum
In 1961, Alan Shepard became the outset American in space. His trip was supposed to be brusque, and then there was no programme for pee. But the launch was delayed for over three hours after Shepard climbed into the rocket. Eventually, he asked if he could leave the rocket to pee. Instead of wasting more fourth dimension, mission control ended that Shepard could safely pee inside his spacesuit. The offset American in space went up in damp underwear.
Fortunately, in that location'due south a toilet on the space station these days. The original toilet was designed in 2000 for men and was hard for women to use: Y'all had to pee while standing up. To poop, astronauts used thigh straps to sit on the small-scale toilet and to keep a tight seal betwixt their bottoms and the toilet seat. It didn't work very well and was hard to keep clean.
So in 2018, NASA spent US$23 meg on a new and improved toilet for astronauts on the International Space Station. To get around the problems of zero-gravity bath breaks, the new toilet is a specially designed vacuum toilet. At that place are two parts: a hose with a funnel at the end for peeing and a small-scale raised toilet seat for pooping.
The bath is full of handholds and footholds and then that astronauts don't drift off in the heart of their business. To pee, they tin can sit or stand then concur the funnel and hose tightly confronting their skin and then that cipher leaks out. To poop, astronauts lift the toilet hat and sit down on the seat – just similar here on World. But this toilet starts suctioning as soon as the chapeau is lifted to prevent things from drifting away – and to command the stink. To brand sure that there is a tight fit between the toilet seat and the astronauts' behinds, the toilet seat is smaller than the 1 in your business firm.
Afterward the deed is done
Pee is more than 90% water. Since water is heavy and takes up a lot of space, information technology is ameliorate to recycle pee rather than bring up clean water from Earth. All astronaut pee is collected and turned back into clean, beverage h2o. Astronauts say that "Today's coffee is tomorrow'due south java!"
Sometimes, astronaut poop is brought dorsum to Earth for scientists to report, but most of the time, bathroom waste – including poop – is burned. Poop is vacuumed into garbage bags which are put into closed containers. Astronauts also put toilet paper, wipes and gloves – gloves assist go on everything clean – in the containers too. The containers are and so loaded into a cargo send that brought supplies to the space station, and this transport is launched at Earth and burns up in Earth's upper atmosphere.
If you've ever seen a shooting star, it might have been a meteorite called-for up in Earth's atmosphere – or information technology might have been flaming astronaut poo. And the next time you have to pee or poop, be thankful that you're doing it with gravity's help.
