Overheat or cool too much. >> the space walk was not the first option. the attempt was to repair it remotely and that did not work. in your description of it being a simple repair. if it can't be done remotely, why are they at this point with the space walk? >> they are at the point with the space walk -- this is the thing that separates it from being simple to complex. space walks are risky. they have to do the repair outside because the pump module that holds the valve is on the exterior of the space station on the main truss. they have to go outside, remove all of the connections that carry...
