CNN – People have many questions (and misconceptions) about space.
It is understandable, given that only 573 people have gone there, according to the number of space expert Jonathan McDowell.
However, they are not the only ones who know the truth about what is happening in the great beyond.
Do not be afraid. NASA responded to some of the most important questions that people absolutely should positively know about space travel. (Are you welcome.)
Where does the astronaut go?
Solid waste is collected in a container as part of the hygiene component of the space station toilet, and these canisters are thrown away during the destructive re-launch of a cargo ship. The urine is collected separately and sent through the distillation system of the station's water recovery system, which helps to transform urine from crew members into usable water.
Do they really eat frozen ice cream in space?
No. Astronauts do not eat dry with frozen ice cream, but sometimes a space ship for cargo delivery carries a special treat of real ice cream. Sending ice cream is sometimes possible when there is space in one of the freezer pads on the way up which will be filled with scientific samples for the return of the SpaceX Dragon. It is normal for retailers to deliver astronauts a small amount of fresh food (usually fruit or vegetables) with ice cream just to travel from time to time.
Are there explosions if they do not wear suits?
No, but you're going to die. Without protection, the astronaut would die in space quickly because of the lack of oxygen and enormous physical pressure. Cold and radiation are also quite dangerous. Life jackets provide breathing air, drinking water, pressurized environments and extreme temperature protection.
What happens when astronauts get sick?
Astronauts tend to be very healthy because they work more than two hours a day and live in a closed environment. But they have access to physicians via video or telephone, and the space station has a variety of medical devices and pharmaceuticals to treat astronauts who can get sick in space.
Can people really get taller?
Yes. Without a gravitational force that compresses the astronaut's spine, the fluid between the discs fluctuates as they temporarily expand, creating an elongation effect. We experience the same effect while we sleep flat at night, albeit to a lesser extent. In space, the astronaut will sometimes "grow" two centimeters higher. But this effect disappears as soon as they return to Earth's gravity.
How do we understand that gravity exists in space?
On Earth we are experiencing gravity, but astronauts at the space station are in a kind of constant free fall around Earth that holds them in orbit, and thus they experience what is commonly called zero gravity or microgravity, whereby they can fly and fly through the space station.
Is it true that nobody can hear you
No air to transmit sound waves, screaming will not be heard in space ̵
