Improptu Space Walk on the ISS, a First for NASA!

Spurred by a recent Ammonia leak, astronauts aboard the ISS took the uncharacteristic action of instituting an EVA Saturday with the plan of finding the leak that if left unchecked, would leave the station without power in a few short hours. 

Astronauts Thomas Marshburn and Christopher Cassidy, prepped for the walk shortly after the discovered leak on Thursday and exited the station Saturday, proceeded to the source of the leak where they replaced a suspected pump, in a closely scrutinized five plus hour EVA.  

NASA is still unclear as to the cause of the leak so  it remained unclear whether the issue had been entirely resolved.   (note yellow circles in top photo show Ammonia flakes streaming from the unknown leak)
