Discovery on its 120th shuttle mission
The U.S. space shuttle Disovery program has launched the 120th flight – including Discovery's mission that was recently launched into the space. The Discovery Space shuttle has taken off on its 34th flight and the third of four shuttle missions for this year of 2007.
The Harmony module aboard the shuttle is the first new addition to the space station's living space since September 2001.

The spacecraft with which NASA intends to replace the shuttle, called Orion vehicles, are being designed to dock at Harmony.
