How do Astronauts Live in Space?

Almost everyone has a question or two about living in space. What do astronauts do in space? How do they do everyday things like eat, sleep and go to the bathroom? Well, this is our attempt to answer those questions!

It's important to note that astronauts do many of the same things we do here on Earth. They still use the same soap and shampoo, but sponge baths are more common than showers because it takes a lot of time and effort to take a shower. They exercise a lot to stay in shape and they also eat nutritious, but sometimes unpleasant, food.

You might be wondering how astronauts sleep at night. Well, they don't just float around in a room! Each astronaut hops into a sleeping bag attached to the wall and sleeps there. Otherwise, they would constantly bump into things!

Which brings us to the interesting question of "how do they use the bathroom". Without going into too much detail, let's just say there are bags that collect the waste. And of course, there is a seat belt to keep you from floating off the seat!
