Astronauts made a hasty spacewalk after a computer failed outside the ISS. The spacewalk took about 2.5 hours.
Acclaimed commander Peggy Whitson and engineer Jack Fischer floated outside the space station to replace the computer. The computer failure posed no threat to station operations but NASA management wanted it to be replaced nonetheless.
While Whitson took care of the computer replacement, Fischer installed wireless communication antennas.
This spacewalk puts Whitson third on a list of astronauts with the most spacewalks.
