Urgent space station repairs [PHOTOS\VIDEO], Two U.S. astronauts completed an urgent spacewalk to make emergency repairs to part of the International Space Station ahead of schedule and without incident, NASA said.
In fact, the walk went so well the pair were able to get a head start on work scheduled for a second spacewalk Monday -- and if that trip goes according to plan they will all be able to scrap a third scheduled walk and take a day off on Christmas, NBC reported.
The astronauts, Rick Mastracchio and Mike Hopkins were forced to repair an ammonia-fueled cooling module. Go here for photos and video of the incredible repair.
