There must not be AAA in space. After a radiator leak at the International Space Station began sending white flakes of ammonia into space, a NASA spokesman said an emergency spacewalk may be necessary to fix the problem. Though the spokesman called the spacewalk only a “possibility,” astronauts at the space station are sending tweets that make the ordeal seem a certainty: “Good Morning, Earth! Big change in plans, spacewalk tomorrow, Chris Cassidy and Tom Marshburn are getting suits and airlock ready. Cool!”
