Station's power relies on ammonia coolant, and a couple of hours ago (Thursday May 9) the crew found that the ammonia of one cooling loop was leaking into space. This could lead to a shutdown of said cooling loop in about 48 hours.

Quoting NoUFO (Reply 2): EVA will be tomorrow (Saturday) by C. Cassidy and T. Marshburn.
EVA is time-critical because if the pressure drops too low the loop will auto-shut down, and the residual pressure may not be enough to produce the current stream of ammonia flakes, a simple and effective visual aid to pinpoint the leak. IIRC the latest such leak (late 2012) couldn't be found for sure.
