CAPE CANAVERAL (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.
