While many people may spend Christmas Eve doing last-minute shopping, two American astronauts have a more challenging matter to attend to Tuesday. In orbit more than 200 miles above Earth, flight engineers Rick Mastracchio and Mike Hopkins embarked on a spacewalk on Tuesday morning to repair part of the International Space Station's cooling system. It is the second Christmas Eve spacewalk in history, according to NASA.
