Atlantis astronauts complete final spacewalk

UNDATED (WKOW) -- Two Atlantis astronauts took their final spacewalk at the International Space Station on Friday.

They replaced some batteries and installed a new jumper cable on the station, which completes the astronauts' work in outer space.

Atlantis is scheduled to undock from the space station on Sunday and head back to Earth.

Only two more shuttle missions remain after this one is finished.
