Astronautics Question:

Astronauts on the space station stay busy. There is a lot of work to operate the many science experiments on board. The crew also has to make sure that the station is in top shape, so they clean, check equipment, maintain and repair or replace broken equipment. Crew members also must exercise two hours each day to stay fit and keep their bones and muscles strong. Sometimes we need to do a spacewalk to work outside the station in our space suit. It's a tough and dangerous job but the view is terrific.
