An upcoming delivery mission may be delayed because of the cooling system trouble.

family during the holidays is not optimal," he told the AP. "But if you have to be away from your family on Christmas, then this is sure not a bad place to be."
Mastracchio, an experienced spacewalker, said he's more than ready to go out and make repairs, if deemed necessary by Mission Control.
On Friday, engineers in Houston spent a third day working on the issue. They want to see if they can solve the problem remotely, before ordering up a series of spacewalks to replace the entire pump. Three spacewalks were required to install this pump in 2010.

It's a serious situation that needs to be remedied quickly, officials said, in case there are additional failures.
"Any time you have something like this, it's good news, bad news," Mastracchio told The Associated Press on Friday.
