Astronauts take mission's 3rd and final spacewalk

Two spacewalking astronauts took on cable and antenna work at the international space station Saturday in their final trek outside, but encountered last-minute difficulty with a connector and had to leave one job undone.

Lead spacewalker Danny Olivas and his partner Christer Fuglesang unreeled 60 feet of cable for a new room that will be added to the orbiting complex early next year. The pair also hooked up a couple of Global Positioning System antennas and replaced some electronic equipment in their second excursion in three days.
