Space station getting extra storage room

The International Space Station is getting an extra storage room.

Space shuttle Discovery delivered the new compartment over the weekend.

The orbiting astronauts will install the 21-foot-long chamber Tuesday morning. It's loaded with supplies as well as a humanoid robot that will be tested as a potential astronaut helper.

The Italian-built chamber is named Leonardo, after Leonardo da Vinci. It flew seven times to the space station as a temporary cargo carrier. This time, it's staying.

Discovery's last flight will last an extra day. Mission Control radioed up the news following Monday's spacewalk. The 12-day mission will now end next Tuesday. Once Discovery lands, it will be retired and put in a museum.
