I think it is both. But they have also made it clear in the briefings. They can control the risks on a space walk more so than they can control the risk during reentry. Since they don't have enough information to know one way or the other, they will take the safer approach. They know the shuttle underbelly was designed to be smooth and if it is smooth, then the can have confidence in that. After ever more foam shedding and the Columbia disaster, I'm sure they don't want to take any chances if it's a risk they can mitigate. Since this is one they can they should. I guess what it really points to is the lack of other major on orbit problems they are having. That's a good thing. <div class="Discussion_UserSignature"> </div>
