It's Unpacking Day for Astronauts at Space Station

Monday was unpacking day for the astronauts at the international space station. Among the top items to be hauled into the space station: a new toilet and a contraption that purifies urine and sweat into drinkable water at the orbiting outpost.

Using a giant robot arm, Endeavour's astronauts grabbed onto a cargo container in the shuttle payload bay late Monday morning for its installation on the space station. Inside the 21-foot-long canister is almost 15,000 pounds of equipment that will allow the space station to expand from three to six crew members next year -- "the goodies," according to the space station's commander, Mike Fincke.

"It's a big day in front of us," Fincke called down. "We're here to work, and this is the can-do crew."
