The astronauts wipe their body clean by using a wet towel, and wash their hair by using waterless shampoo. Since water does not flow in a zero-gravity environment, the astronauts cannot wash their hands under a faucet as you do on Earth. So, there are no sinks or showers inside the space shuttle.
Do astronauts drink pee?
Astronauts have been drinking recycled urine aboard the ISS since 2009. However, this new toilet makes the process more efficient and more comfortable.
Would phones work in space?
No. Take an ordinary smartphone and put it in outer space and you've got a big problem: Inadequate cooling. The phone is going to destroy itself with its own heat. Normal conduction and convection cooling will not work, all you have is radiation and at those temperatures it's a small part of the cooling.
Why can't astronauts burp in space?
On Earth, gravity pulls liquids and solids to down to the bottom of our digestive systems, while gases stay up top and get forced back up the esophagus as a burp. That can't happen in space. Without gravity to separate them, “the air, food and liquids in your stomach are all floating together like chunky bubbles.

Is alcohol allowed in space?
“Alcohol is not permitted onboard the International Space Station for consumption,” says Daniel G Huot, spokesperson for Nasa's Johnson Space Center. “Use of alcohol and other volatile compounds are controlled on ISS due to impacts their compounds can have on the station's water recovery system.”
Can you fart in space?
Surprisingly, that isn't the biggest problem associated with farting in space. Though you're definitely more likely to worsen a small fire when you fart, it won't always injure or kill you. The worst part about farting in space is the lack of airflow. Let's take a step back and remember how farting on Earth works.
How do female astronauts deal with their periods?

Does the ISS have Wi-Fi?
Yes, the International Space Station that is ISS has the facility of Wi-Fi connection. The speed of this Wi-Fi is very high but not for the use of astronauts. This Wi-Fi connection is used to transfer data from the spaceship to other satellites and Earth at NASA itself.
Is Internet available in space?
Yes, the International Space Station has an internet connection. Previously, astronauts could only send emails and Tweets to ground control as part of their regular data transmissions, and then ground control would have to send their communications for them. They upgraded in 2010.
Do you age less in space?
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
Do we sweat in space?
Space station astronauts exercise two hours every day to counter the muscle- and bone-withering effects of weightlessness, quickly leaving their workout clothes sweaty, smelly and stiff.
How do you sleep in space?
The astronauts sleep in small sleeping compartments by using sleeping bags. They strap their bodies loosely so that their bodies will not float around. In the zero-gravity world, there are no "ups" or "downs".

How do astronauts brush their teeth?
The Brushing Process
