CNN – People have a lot of questions (and misunderstandings) about space.
It is understandable to assume that only 573 people ever went there, according to a census of space expert Jonathan McDowell.
Still, they should not. It's not the only ones who know the truth about what's happening in the Great Beyond. Right?
Do not be afraid. NASA has answered some of the key questions that people need to know about space travel. (You're welcome.)
Where is Astronaut Poop going?
Solid wastes are collected in a canister as part of the space station's garbage hygiene component and these canisters are disposed of during the destructive reentry of cargo spacecraft. The urine is collected separately and passed through the station's water recovery system's distillation unit, which helps convert the crew's urine into usable water.
Do you really eat freeze-dried ice cream in space?
No. Astronauts do not eat freeze-dried ice, but sometimes a spacecraft with cargo replenishment brings a special treat of real ice. Sending ice cream is sometimes possible when there is room in one of the freezers on the way up, filled with scientific samples for the return journey from SpaceX Dragon. It is normal for commercial replenishment missions to only occasionally add a small amount of fresh food (usually fruit or vegetables) to the astronauts with ice.
People explode if they do not wear space suits?
No, but you will still die. Without protection, an astronaut would quickly die in space due to the lack of oxygen and the enormous physical pressure. The cold and radiation is also pretty dangerous. Space suits provide air for breathing, water for drinking, a pressurized environment for working and protection from extreme temperatures.
What happens when astronauts get sick?
Astronauts are usually very healthy as they spend more than two hours a day training and living in a closed environment. But they have access to doctors via video or phone, and the space station has a variety of medical equipment and medicines that can be used to treat astronauts who become ill in space.
Can people really get bigger?
Yes. Without gravity squeezing the spine of an astronaut, the liquid swings between the discs as it temporarily expands, resulting in an extension. We experience the same effect when we sleep flat at night, albeit to a lesser degree. In space, an astronaut sometimes "grows" two inches larger. However, this effect disappears as soon as they return to Earth's gravity.
How do we know that gravity exists in space?
On Earth, we feel the gravitational force of gravity, but space station astronauts are in a sort of perpetual freefall around Earth, keeping them in orbit, and so they experience what is commonly referred to as weightlessness or weightlessness where they can float and fly through the space station.
Is it true that no one can hear you? Scream?
Without air to transmit sound waves, a scream in space would not be heard ̵
