Cape Canaveral, Fla. (AP) -- Spacewalking astronauts had to take extra safety precautions Saturday after possibly getting toxic ammonia on their suits from the International Space Station's external cooling system.
Victor Glover and Mike Hopkins had no trouble removing and venting a couple of old jumper cables to remove any ammonia still lingering in the lines. But so much ammonia spewed out of the first hose that Mission Control worried some of the frozen white flakes might have gotten on their suits.
