A rare Christmas Eve spacewalk at the International Space Station has proven successful.
It took more than 7 hours, but astronauts Rick Mastracchio and Michael Hopkins braved a mini-blizzard of noxious ammonia as they hooked up the new, refrigerated-sized pump.
The original damage was to part of the cooling loop that had to be turned off.
That halted many science experiments.
It was only the second Christmas Eve spacewalk ever.
