Just try not to think about Gravity. The International Space Station's cooling system failed Wednesday evening, according to NASA. The situation was described as urgent, but not an emergency, as the station focused on conserving power and routing the cooling system through one working loop after a second stopped working. The issue may require a space walk, NASA said, which allows the six on-board astronauts to exit the station.
