Three stories high

The futuristic space habitat is made up of three decks: the top floor is for astronauts’ living quarters, the second floor is for science experiments, and the bottom floor has a centrifuge to recreate gravity-like conditions and reduce the effects of weightlessness on the human body, according to Airbus. A greenhouse tunnel runs through the middle, intersecting all three decks and connecting them together to provide astronauts with the option to grow plants and food in space.
