Fear not. NASA has answered some of the key questions that people need to know about space travel. (You're welcome.)
Solid waste is collected in a canister as part of the waste hygiene component of the space station's toilet, and these canisters are disposed of during the destructive reentry of cargo space vehicles. 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. For commercial replenishment missions, it is normal for astronauts to occasionally deliver a small amount of fresh food (usually fruit or vegetables) with ice.
People explode if they do not wear spacesuits?
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 because they work out more than two hours a day and live in a closed environment. However, 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 might get sick 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 gravity.
