Space has no gravity. So living in space is difficult because you float everywhere. You need to be hooked up if you want to stay in one place. You can do regular things in space that you do on Earth, but they are done a little differently. Foods are prepared on Earth and heated in the oven on the shuttle. When astronauts eat they have a tray that they can attach to their lap or the wall. The tray holds the for so it doesn’t float in to the air they eat brownies, macaronis, fruit.
