While many people may spend Christmas Eve doing last-minute gift shopping, two American astronauts have a more challenging matter to attend to Tuesday.
In orbit more than 200 miles above the planet, Flight Engineers Rick Mastracchio and Mike Hopkins are set to embark on a spacewalk to repair part of the International Space Station's cooling system.
It will be the second Christmas Eve spacewalk in history, according to NASA.
The two engineers will be carrying out the second in a series of expeditions needed to replace a malfunctioning pump, which circulates ammonia through loops outside the station to keep equipment cool.
