NASA gives us a tour of the International Space Station, "a manned research space facility that is being assembled in orbit around the Earth." Video after the jump.
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
