The training kicked in and we quickly went through our emergency procedures, I took manual control and I got the spacecraft under control and stopped about 50 meters from the space station. So, the net effect of the failure was that we were actually turning and speeding up towards the space station when we should have been slowing down, so it was quite a dangerous situation. But we got manual control, performed the first manual docking to the station at night. The training pays off. It was just automatic. We had our books out already, we went right to the right procedures and executed them.

The expense of getting into space is the rocket launch, the rocket itself. Rocket's right now, commercial rockets cost probably somewhere between $50, or $120, or $150 million per launch. And those are all expendable. That is, you've got to buy a new rocket for each launch. So, that really is the critical part. If there was some kind of really, a revolutionary breakthrough and the price of rockets fell by an order of magnitude, I mean, just imagine what that would do as far as getting access to more ordinary people.

As commander I was responsible for the overall success of the mission, and so I had to know at least a little bit about everything.

Space is very unforgiving business

I hope that China will continue with space exploration. It would be logical to have international co-operation. I hope that it will come about and that I can be involved in it.

The most important thing about an astronaut is you have to take for a given a person's done pretty well in school, has the intelligence and all of that to learn new systems and new things. But after that, the most important thing I think is being able to get along with others. Flexibility and teamwork, those issues because as we fly longer and longer in space, those are really important factors, even on short shuttle missions, those are important factors, to put a crew together that can work together effectively as a team, that can get along.

It was in the back of my mind, even while I was going to school, but it wasn't until I was at university studying engineering that I thought, well what do I really want to do? And I kind of came back to that and I said, well the degrees I'm trying to get are going to qualify me to apply. And so, that's what I did after I finished my, or after I was getting my doctorates. That's when I first applied to NASA.
