In the not to distant future, men and women will be living in space to carry out numerous experiments and activities. Rather than being confined to shuttles or orbiters, our space pioneers will live in Space Stations, built largely in space. These orbiting multipurpose systems will have to provide for all the astronauts' needs, including atmosphere, food, water, shelter, and health. These space stations will also have to create their own living space. For instance, an atmosphere cannot be brought with them. They will have to maintain the atmosphere by using certain plants or other methods. Waste materials will have to be stored, reused, or transported. Gravity will have to be maintained, because human bone will deteriorate without gravity. Emphasize to students that the human body was made to live on Earth, with an atmosphere, water, and gravity.

Also note how the Space Shuttle is important is working on different missions, like putting satellites in orbit. PROCEDURE:
