The International Space Station (ISS) will be a little “city in space” orbiting 250 miles above the Earth. About the size of two football fields, the space station will be a place where people from around the world can live and study in space over long periods of time. The many modules of the station—from its laboratories to living quarters to power sources—will be constructed in space.
 
The ISS is the most ambitious and expensive construction project ever attempted, but it will someday serve as a stepping-stone for future space exploration.
