CAPE CANAVERAL, Fla. - Astronauts are fixing and hauling equipment aboard the linked Atlantis space shuttle and International Space Station, as the last shuttle flight draws closer to an end.

Atlantis' pilots got a jammed storage locker open Saturday and retrieved air purifiers for the space station. They also brought back online a computer that failed two days ago. NASA wants to run more diagnostic testing, but so far the computer seems to be working fine.

Station residents fixed a treadmill.

Atlantis delivered tons of food and other supplies to the space station. The cargo canister is being filled back up with station trash for return to Earth on Thursday.

Meanwhile, the celebrity wake-up calls continue. The latest Earth-to-space greeter: singer Beyonce.
