The ISS travels at a speed of 17,500 miles per hour (five miles per second), orbiting Earth every 90 minutes. An international crew of six people live and work on the station, which has been continuously occupied since November 2000. In that time, 222 people from 18 countries have visited the station. Crew members spend about 35 hours each week conducting research that advances scientific knowledge in Earth, space, physical, and biological sciences for the benefit of people living on our home planet.
The space station has grown and evolved into an unprecedented, state-of-the-art laboratory complex. Offering a microgravity environment that can’t be duplicated on Earth, the ISS continues to further humankind’s knowledge of science and how the human body functions for extended periods of time in space — all of which will prove to be vital on long-duration missions beyond low-Earth orbit, including to Mars.
Now, the European Space Agency (ESA) has made it possible to take a narrated 3D tour of the International Space Station (ISS). Visit all the modules of humankind’s weightless laboratory orbiting 400 km above the Earth.
The narration is available in six languages:
