JEANNE MESERVE, CNN ANCHOR: And now back to the Kennedy Space Center in Florida where the liftoff of space shuttle Endeavour is just minutes away. CNN space correspondent Miles O'Brien is following the action there and joins us now live -- Miles. Well, Jeanne, we can't tell you exactly how many minutes away it is because they're in an extended hold right now, the clock holding at T-minus nine minutes. It was supposed to be a 10-minute hold, but NASA has a few minor problems it is working through. One of them was, in closing the crew hatch, they had some difficulty feeling satisfied that the pressure inside the crew cabin was adequate. They have since resolved that particular problem. They have a problem now which they're trying to address which relates to a hydraulic circulation pump sensor. Right now, they're troubleshooting that over in the launch control center which is just a few hundred yards from where I sit. They are saying right now they expect it to be a very short delay. But, nevertheless, we are T-minus nine minutes and holding, the shuttle Endeavour still unable to end its numerous delays trying to get off the ground. It's now been five months since this mission was supposed to fly originally. The six astronauts are strapped in, obviously, ready to go, the shuttle fueled up. All systems are otherwise go. We, of course, will be watching it very closely, and the moment this countdown clock starts ticking downward, we will bring it to you live. Miles O'Brien, CNN, reporting live from the Kennedy Space Center.</s>MESERVE: Thanks, Miles.
