>>> something that sounds like it's aught out of hollywood. nasa engineers are working to fix something that could require a space walk . tom, what can you tell us?

>> reporter: it's nothing that serious as sandra bullock up there on the space station . this is not an emergency and the crew is safe. but nasa is still working to determine what shut down a cooling system on the space station for a time yesterday. they suspect it's a faulty valve and they're hoping a software patch will fix this, but if that doesn't work, they could eventually have to perform a space walk . after the system went down, the astronauts turned off noun u non-essential systems and on board right now, three russian, two americans and one japanese astronaut. space walks have not been allowed since an italian was filled with water during a space walk last july. that's the thing, it understands why that happened. it likely would okay a repair walk, if necessary. they are hoping that a software patch will be the permanent fix on this.
