Astronaut Michael Barratt (Expedition 20 Flight Engineer) walks you through the International Space Station in this 20-minute long HD video, which covers the entire 167 feet of the space station's pressurized modules.

Barratts' commentary describes to Mission Control in Houston how equipment and supplies are arranged and stored, and provides engineers with a detailed assessment of each module-to-module hatchway.
