This is a tour given by NASA for us to learn more about one of the most challenging projects, the International Space Station.
Watch the video after the break.
Due to the ISS, there is always a permanent human presence in space, as there have always been at least two people on board ISS since the first permanent crew entered the ISS on November 2, 2000. It is serviced primarily by the Soyuz, Progress spacecraft units and Space Shuttle. The ISS is currently still under construction with a projected completion date of 2010.
