CAPE CANAVERAL, Fla. — 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.
