<i>Conspiracy Theory: What if Griffin knows NASA is going to take a financial hit soon (Katrina, Rita, Iraq), and he would prefer to see STS/ISS take the brunt of the cost reductions while keeping the new plan in place?</i><br /><br />That's my fear. Look, nobody is arguing that we shouldn't begin the retirement process for STS. In fact, I believe some subcontractors have already started to shut down, as NASA has more than enough of certain components for the remaining flights. But let's at least get through the addition of the remaining ISS solar arrays, Node 2, the Columbus module, and the Japanese Experiment Module, and hopefully fly a final Hubble servicing mission, before retiring the shuttle fleet! That's what we said we would do, and I think it's clearly the right thing to do. We could probably accomplish what I just outlined with no more than a dozen flights!
