ISS spacewalk interrupted by suit malfunction

A Russian cosmonaut just dealt with a rare spacesuit problem. As CNN's Jackie Wattles observed, mission control ordered Oleg Artemyev back to the International Space Station's airlock after encountering a suit issue. While the exact nature of the trouble wasn't clear as of this writing, NASA commentators noted a "slight fluctuation" in the suit's battery power. Artemyev returned safely, plugged into the station's power supply and resumed operations. We've asked NASA for comment.
