A pair of Discovery astronauts embarked this morning on repairs to a ripped solar panel on the International Space Station in one of the most dangerous and challenging spacewalks ever undertaken, the AP reports. Astronaut Scott Parazynski took a 45-minute trip on a modified robotic arm to the station's far left end and began to wrestle with the extending mechanism for the highly electrified panel.
At the site, Parazynski installed a brace on the solar panel with a delicate maneuver. "Well done," said Discovery commander Pamela Melroy, who then warned him to be careful. Parazyinki then began snipping mangled wires from the rip. A camera on the astronaut's helmet conveyed pictures of the damage to Mission Control.
