Two astronauts fixed the broken solar panel on the international space station today in one of the riskiest spacewalks ever undertaken, the AP reports. Scott Parazynski installed a brace and fixed snarled wires on the highly electrified panel, which then unfurled to its full length. "Excellent work guys, excellent," said the space station commander.
Parazynski and fellow astronaut Douglas Wheelock undertook the mission because the newly installed solar panel—critical to the future of the space station—encountered a snag on Thursday. "What a relief," said Parazynski, who completed the far-from-home-improvement while perched atop a 90-foot robotic arm. He and the rest of Discovery's crew are scheduled to return to earth on Wednesday.
