Astronauts on the International Space Station a busy schedule. Every day they at 7:00 GMT. From 7:00 to 8:00, they wash up and breakfast. At 8:00 in the morning, they to Ground Control in their countries. After they talk to Ground Control, their workday . The astronauts (not) the same thing every day. Their schedules change every week. The astronauts do not work all the time. Each day they for an hour in the morning and an hour in the afternoon to keep themselves fit. After dinner, they free time for an hour. Then, it time to go to sleep. Sometimes this (not) easy because the sun rises and sets 16 times each day on the space station!
