CAPE CANAVERAL, Fla. (November 21, 2009)—Two Atlantis astronauts were taking another spacewalk outside the International Space Station Saturday.

One of the spacewalkers, Randolph Bresnik, is still awaiting word on the birth of his daughter.

His wife, Rebecca, was due to give birth Friday.

NASA officials said if the baby is born during Saturday's spacewalk, they may wait to pass along the news because they want Bresnik focused on his job.

It's the first spacewalk of Bresnik's career.

He ventured out Saturday morning with veteran Michael Foreman.

The two were performing some space station chores.

The spacewalk was delayed more than an hour by false decompression alarms that rang through the orbiting complex Friday, for the second night in a row, disrupting spacewalk preparations.
