Astronaut embarks on space walk

On Saturday morning, astronaut Scott Parazynski stood on the end of a 60-foot robotic arm to mend a solar array.

Armed with a heavily reinforced space suit and some needle-nose pliers, Parazynski stepped outside the International Space Station and worked on the repairs for seven hours and 19 minutes — all the while avoiding contact with the solar panels, which could transmit electricity.

The space walk put Parazynksi farther from the safety of the airlock than any previous astronaut. The walk took Parazynksi so far out of range that returning to safety would have required more than 30 minutes of oxygen.
