'Twas the night before Christmas, and high above your house, U.S. astronauts Mike Hopkins and Rick Mastracchio repaired the International Space Station.
It took nearly seven hours for the two men to successfully remove a degraded pump module and start up a new one. The engineers completed the repairs in two parts; the first on December 22, and the second on December 24. It was just the second time in NASA history a spacewalk occurred on Christmas Eve.
