On the International Space Station astronauts are having problems that can be solved. For example, in the space the austronauts' clothes will get dirty and they can't wash them, so they will throw them in the rubbish bin. Also they won't know when to go to sleep because there's no day and night, so they will have a 24-hour timetable and always they will go to bed at the same time. And finally, food will fly around the space station, so if food doesn't stay on a plate, they will eat from bags.
