Astronauts Step Out on 1st Spacewalk of Mission

Two astronauts are continuing a spacewalk outside the International Space Station.

Michael Foreman and Dr. Robert Satcher have hustled through a considerable list of chores already. They managed to get a spare antenna installed in two hours. They've also hooked up cables and a handrail, and greased some mechanisms.

At one point, they found themselves two hours ahead of schedule, so they tackled some extra work.

Satcher is an orthopedic surgeon, the first ever to travel into space. As he lubricated an attachment for a robot arm, astronaut Randolph Bresnick commented from inside the linked shuttle and space station that it's "a thing of beauty to see a good doctor at work."

Two more spacewalks are planned during Atlantis' stay at the outpost. The crew is scheduled to head home the day before Thanksgiving.

Atlantis will remain at the space station until Wednesday.
