Well, I was researching this and I will tell you about a normal day in the space of an astronaut. The first U.S. astronauts were selected in 1959. Astronauts aboard the ISS spend much of their time conducting scientific experiments in zero gravity conditions. In many cases, this theoretical research is intended to lead to practical applications on Earth. Astronauts are typically stationed aboard the ISS for six months and must exercise regularly to prevent bone and muscle issues. Eating meals in space is no ordinary activity. Like on Earth, astronauts eat three meals per day. Some foods are available in their natural forms, such as brownies and fruit. As on Earth, astronauts sleep eight hours and wake up according to mission schedules. Unlike on Earth, however, astronauts can sleep in any position due to zero gravity. To prevent injury, astronauts must tether themselves to avoid floating about the station in their sleep.
