Astronauts Spacewalk Looking to Find Radiator Leak

 CAPE CANAVERAL, Fla. (AP) _ Two astronauts are spacewalking outside the  International Space Station in an attempt to find an ammonia leak in a critical radiator system.
 
 Station commander Sunita Williams and Japanese crewmate Akihiko Hoshide ventured out Thursday morning.

They will isolate plumbing to help flight controllers locate the leak and open a spare radiator.
 
 Their spacewalk got under way just hours after the orbiting lab had to dodge a piece of space junk.
 
 On Wednesday evening, thrusters on a docked Russian supply ship were fired to move the space station out of harm’s way.

But a computer error caused the thrusters to malfunction, and the station did not reach the desired altitude.
 
 NASA says the station and its six residents are safe despite their lower-than-intended orbit.

The menacing debris is a satellite fragment.
