There is nearly 16,700 cubic feet of habitable area aboard the International Space Station (ISS). The guided tour begins in the Columbus Laboratory Module—the European Space Agency’s (ESA) contribution to the station that includes equipment for studying fluid physics, materials sciences, and the effects of microgravity. Step Inside the International Space Station (POV Tour)Along the way, viewers get fascinating looks at life in space, including what it’s like to eat in zero gravity and how difficult it is to navigate through all the controlled chaos. Humans have lived continuously aboard the ISS for over 25 years, but the historic endeavor is fast approaching its retirement. After that, the station will fall back towards Earth and burn up safely during atmospheric re-entry.
