HOUSTON, Dec. 21 (UPI) -- Two U.S. astronauts completed an emergency spacewalk to repair 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.
