Astronauts Spot Rip on Solar Panel, AP
"Spacewalking astronauts bolted a solar power tower to the international space station on Tuesday, completing an ambitious three-day moving process that ended with elation when the beam's giant solar panels began to unfurl. Their joy turned to concern, however, when a rip was spotted in the second solar panel. NASA needs to get the tower up and running to prevent malfunctioning station equipment from delaying the addition of a much-anticipated European research lab."
