Living in space is definitely not for everyone. Astronauts have to be very patient and able to withstand tons of pressure during liftoff and landing, different from here on Earth, and the feeling of weightlessness. Astronauts live in one small space for up to 2 ½ weeks. They eat, sleep, do experiments, etc. in the same rooms. Months before the launch, astronauts choose what clothing they will wear when in space. They change clothes every 10 days and change underwear every 2 days. When launching and landing, Astronauts wear the orange suits that everyone knows of. When sleeping they sleep in a sleeping bag type thing that is strapped to the walls or floors. Their sleep hours are also normal, just like ours. Although the living may not be spectacular, the food isn't that bad either. They are able to eat brownies, fruit, spaghetti, macaroni, ketchup, mustard and mayonnaise. They have salt and pepper but it is in liquid form. In the shuttle they have an oven but no refrigerator and they eat three meals a day just like us. The food used to be in squeeze tubes, like toothpaste tubes. And as you can probably tell that wasn't very appetizing. In space they have the same hygiene as on Earth. They wash their hair using rinse less shampoo, brush their hair, shave, brush their teeth, and use the bathroom. When in space the astronauts perform science experiments, assemble the international space station, and capture huge satellites. They are often fixing things and always checking their support systems and filters to make sure nothing is going wrong or will go wrong. As you can see there are lots of things that go into being an astronaut. People that are training to be an astronaut have to train for a couple years before they are even chosen to be able to go into space, so you could do all that training and not even go into space. You may think that there are only a couple people to make this work but really there are relatively 30,000 people to make sure everything goes correctly.
