Christmas has finally arrived for the six space station astronauts.
Two space station astronauts have floated outside on Christmas Eve in hopes of wrapping up urgent cooling system repairs.
Astronauts removed an old space station pump Saturday, sailing through the first of a series of urgent repair spacewalks to revive a crippled cooling line.
Among the lucky candidates: the first female fighter pilot to become an astronaut in nearly two decades. A female helicopter pilot also is in the group.
Two astronauts on the International Space Station are preparing for a possible impromptu spacewalk to work on a leaking coolant line.
NASA’s future plans to explore Mars may end up using astronauts as space messengers.
Astronauts may have had the ‘right stuff’ to go to the moon, but when it comes to keeping track of what they brought back, NASA seems to have misplaced some of that stuff.
