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.

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

It's really too difficult to predict.
