How was the ISS built?

The ISS is the result of the collective effort of many countries and is the largest spaceship in orbit around the Earth. The construction commenced int 1998 and was scheduled to end in 2010. The ISS is composed of different components called 'modules'. The first was the drive module made by Russia, and this was followed by the living module and many other components, which were brought to the growing station by American space shuttles or by Russian proton rockets. As the ISS is constantly manned, supply flights carrying food, water, oxygen, and spare parts are sent to it frequently.
