Astronauts floated into the newest addition to the international space station today and formally christened the sparkling white room known as Harmony.

Space station commander Peggy Whitson and Italian astronaut Paolo Nespoli -- shown above with an unidentified astronaut -- were the first ones in.

The chamber was named by schoolchildren in America and was made in Italy.
