[i]There has been a very thorough set of troubleshooting and testing that was performed by us, NASA and our suppliers and a detailed fault tree was developed. The first step to understanding what you're going to do next is understanding what the root cause is. And so that has been agreed to by the team that did the troubleshooting and the testing, based on all those results. Now we have a mitigation for OFT-2. The second step is, where do we go from here? There's still a little bit more testing that has to be completed. We have to close out a couple other areas on the fault tree, but we're already looking at different options for what we do for CFT [the crew flight test] and what we do for the missions after that. It has not been decided exactly what we're going to do yet, but I can tell you that a redesign is definitely on the table, and once we get all the information that we need, we'll make that decision.[/i]
[i]I really don't have anything to add to what Mark said. Now that we understand root cause and understand the factors, we'll go look at it and participate with Mark and the team and see what areas, as Mark talked about, we go and enhance the valves with — different materials, different way to seal it, those sorts of things. NASA is heavily engaged in participating.[/i]
