The station is big

The International Space Station is considered the most complex scientific project in the world. It is about the size of an American football field. Once it is completed, it will consist of 16 pressurized modules that make up the laboratories, living quarters, airlocks, docking stations and more. The different modules are contributed by NASA, the Russian Federal Space Agency or the European Space Agency. As many as 10 multinational space travelers can inhabit the International Space Station at the same time, arriving by Russian spacecraft, the recently retired space shuttles and private space flight. This photograph, taken in 2009 from the Russian section of the orbital outpost, shows the sun rising on the International Space Station.
