We're still going to be able to accomplish our goals for a good station configuration for shuttle retirement. In our schedule and planning we assumed that we'd have some shuttle problems along the way.

We think that's the best thing to do, just take it off. I think we ought not to think about May right now.

We're going to have to make some modifications to the tank, so that probably puts the September (launch) window into a not very likely possibility.

It's great that our Russian partners are here to help us during this time. It would never have occurred without the tragedy of Columbia. So out of that tragedy has come a remarkable relationship between our two countries and our two space programs.

There's lots of options being investigated. We're not really sure where things are right now.

It looks like it's going to be very unlikely that we're going to be able to just remove the...ramp and fly.
