Life in space can be very different from life on Earth. Because of the zero gravity environment, you have to adapt to things like showering and sleeping in zero gravity. When you go to sleep in space, you have to be strapped down or you will float around. You have to shower with a sponge, because if you showered the way you normally would on earth, the water droplets would float around the space shuttle and could be a danger by getting into the vents or in the astronauts' eyes. Those are only a few things that are different in space, some hazardous and some can be very fun. In zero gravity, you cannot walk around; you have to pull yourself through the air. Since there is no oxygen in space, there is no friction and therefore nothing to stop you when you are moving until you hit something. Food in space has to be made differently then on Earth. Even though space food has evolved since small, dehydrated fruit, there are still many meals that have to be eaten differently in space. For example, salt and pepper particles could easily get in an astronaut's eyes, and so they use a liquid form of such condiments. Most space food is nonperishable, and a lot of it is things like dehydrated fruit. But some foods, like meat, can be eaten naturally with out any special storage in space. Astronauts eat 3 required meals in space, and there is a designated room for preparing and eating food. All of the food comes in packages that might be marked “shrimp cocktail” or “pineapple”. Astronauts eat tortillas instead of bread, because tortillas have a lot less crumbs, and crumbs are like salt and pepper and would float around the cabin. There is lots of work to be done when you're in space. There are a lot of science experiments to be done in space, to see how the microgravity environment affects different types of objects. Space shuttles are also designed to be able to catch satellites and hold them so that the astronauts can repair them. A lot of the science experiments are on humans. Astronauts are tested on how they react to different things in zero gravity, and ways to be efficient in zero gravity are discovered. Space stations are made to be permanent environments, and therefore have a lot more equipment than space shuttles. Living quarters must be designed differently in space. The astronauts have to work out every day to keep their muscles and bones strong, because no exercise is necessary in space and would affect them when they returned to Earth. Working out is also twice as hard, because they have to be tied down to things like treadmills and cycles. Space shuttles have 4 bunks in them, and the rest of the crew has to sleep in strapped down sleeping bags. Water in space is recycled from sweat and other things in space. There is also a designated room for eating, so that the food doesn’t get everywhere. All in all, space is very different from Earth’s environment. I mean, imagine if Earth had no gravity! Our life might be very similar to that of an astronaut’s. Supplies in space are limited and there also needs to be room to bring satellite parts and experiment items. Space can be very dangerous, but it is also a lot of fun!
