CAPE CANAVERAL, Fla. — Astronauts are fixing and hauling equipment aboard the linked Atlantis 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. In more good news, they 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. The cargo canister is being filled back up with station trash for return to Earth on Thursday.

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