This pump has been changed out before. This is the starboard side. Back in August of 2010, we did a pump r&r for a different failure. That was actually a failure of the pump. This is a valve inside the pump module itself. And so, this particular pump is about 3 years old, and so this is not an ISS aging vehicle issue. It's an,  unfortunately, anomaly with the system with a relatively young pump. But it's when you do in mean time between failures, it's all about the averages, so these are the kinds of things that can happen. So we are prepared to do with it. We have 3 spare pumps on orbit, so, we'll take one of those pumps.

 

I feel like we're at a very mature state in terms of being able to go EVA, you know, I looked around the room today and said, what are people worried about? And really, there was not much to be said. So, I think we are ready to go out the door on Saturday. Our team has no lingering, outstanding, showstopping issues to be working out.
