Maybe even more amazing, the Space Station is being built by a team of 17 different countries, including the United States, Russia, and Japan. All the parts of the station, called modules, are built on Earth. Then each module is launched into space. There are about 100 different modules planned. Once the pieces are in space, astronauts put them together.
Robot arms do some of the work.
Then astronauts walk out in space and work by hand to connect all the small parts. Right now the first crew is getting ready to go to their new home in the sky. It will be a historic moving day. They're sure to discover many new and wonderful things in space. But we can say one thing for sure.
