Experience the strange environment of a space station without ever leaving the ground.
Want to know what living on the International Space Station is like? You can experience the closest thing to it here on Earth at Houston's Johnson Space Center, where they have a life-size replica of the ISS to train astronauts.

Before these lengthy missions, which can now last as long as a full year, astronauts train for everything from day-to-day living to emergency procedures.
