I love this photo of Chris Cassidy, one of our great NASA astronauts, at work.  

Astronaut

 

The NASA web site explains:

Repairing the Station in Orbit Expedition 35 Flight Engineers Chris Cassidy (pictured) and Tom Marshburn (out of frame) completed a spacewalk at 2:14 p.m. EDT May 11, 2013 to inspect and replace a pump controller box on the International Space Station’s far port truss (P6) leaking ammonia coolant. The two NASA astronauts began the 5-hour, 30-minute spacewalk at 8:44 a.m.

A leak of ammonia coolant from the area near or at the location of a Pump and Flow Control Subassembly was detected on Thursday, May 9, prompting engineers and flight controllers to begin plans to support the spacewalk. The device contains the mechanical systems that drive the cooling functions for the port truss.

What a thrill it must be for these guys!
