Spacewalkers tackle coolant leak on space station

CAPE CANAVERAL, FLORIDA, Nov 3: –    A pair of spacewalking astronauts floated outside the International Space Station on Thursday to bypass a leak in one of the outpost’s cooling systems. Engineers suspect a micrometeoroid or tiny piece of space debris may have punched a hole no bigger than the width of a hair into one of the station’s radiators. (agencies)
