      CAPE CANAVERAL, Fla. (AP) - It's spacewalking time for the
Atlantis astronauts.
      Garrett Reisman and Stephen Bowen will venture outside the
shuttle Monday morning to install a spare antenna on the
International Space Station. They'll also hook up a storage
platform and loosen the bolts on batteries that will be replaced on
the following two spacewalks.
      NASA may add an extra chore to the second or third spacewalk. A
cable is snagged at the end of the shuttle's inspection boom.
Managers say it should be a quick and easy job to free it. The
problem prevented the astronauts from conducting a proper
inspection of their ship Saturday.
      Atlantis arrived at the space station Sunday. It's the last
flight of Atlantis as the shuttle program winds down.
