 CAPE CANAVERAL, Fla. - The 10 astronauts on the orbiting shuttle-station complex can turn all their attention to hauling things back and forth now that their single spacewalk is over.
 
The last spacewalk of NASA's 30-year shuttle era ended successfully Tuesday. It cleared the way for Wednesday's focus on space station stockpiling.
 
Atlantis delivered a year's worth of food, clothes and other supplies to the International Space Station. Both crews are unloading the cargo carrier that flew up on the shuttle. They will fill it back up with space station trash and discarded equipment for return to Earth next week.
 
The 13-day mission is the last ever for a space shuttle. After that, all three shuttles will become museum displays.
