Third Spacewalk Needed to Repair ISS Cooling System

CAPE CANAVERAL, Fla. (AP) - NASA says a third spacewalk is now
needed to restore a crucial cooling system at the International
Space Station.
Space station astronauts didn't make much progress during
Saturday's urgent spacewalk. The crew had to hammer loose a stuck
connector. Then, an ammonia leak erupted. In the end, Douglas
Wheelock and Tracy Caldwell Dyson were unable to remove the ammonia
coolant pump that failed last weekend.
NASA originally estimated two spacewalks would be needed to
replace the failed pump. After Saturday's trouble, managers say
three will now be necessary. The next spacewalk won't be attempted
until Wednesday at the earliest. Engineers need to figure out the
next step.
NASA says the space station remains in stable condition.
