Of course, you'll have to meet the physical and psychological demands. A space walk takes a lot of energy.

Coming down under a parachute is quite different as well. You hit the ground pretty hard, but all the systems work very well to keep it from hurting, so it doesn't even hurt when you hit. It was a great experience to be able to do both.

I think it's good to have competition. Now we have a third country that can launch astronauts, so it's good for all of us. It makes us a little bit more competitive and wanting to be the leader.

I would say keep supporting space flight, keep telling the public and the politicians why it's important to advance science and explore the galaxy. I encourage the Japanese to keep doing what they're doing.

Our task was doing maintenance and repairs to keep the station in a good state for the return of the shuttle flights and resumption of major ISS construction.

One of my challenges was to try to photograph the Great Wall of China. And I did actually take some photos, but it was hard to discern the wall with the naked eye.

There is no one area of chemical engineering that specifically helped me in my career as an astronaut, it was more the general education in engineering. Also, it was a very difficult and rigorous course. So, it made me strong and resourceful.

The most interesting thing was looking out the window and taking photographs of different places on Earth.

Of course, you'll have to meet the physical and psychological demands. A space walk takes a lot of energy.

Well, it's still a bit uncertain, but I will do the consulting, and I'll see how I can contribute. But I'm sure whatever I do will involve the space program. That's where my passion is.

One day, people will be able to buy tickets to visit space.

I loved flying as much as I thought I would and continue to fly aircraft.

Tinkering is something we need to know how to do in order to keep something like the space station running. I am a tinkerer by nature.

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.

I'm Chinese-American, of course, and so it's very interesting to see China actually launch their own astronauts, becoming the third nation, following the United States and Russia, to do so.

There were different challenges along the way. Certainly the food shortage was unpleasant.

I spent a lot of my time working in the American module, and he would stay in the Russian segment working on his things, and we'd meet up at meal times. So it actually worked out very well.

But a lot of that kind of work is done pre-flight, coordinating efforts with the flight directors and the ground teams, and figuring out how you're going to operate together.

I had done everything I could do as an astronaut, and we have a long line of inexperienced astronauts waiting for their first missions, and so my role really should be to step aside and help them prepare for their missions, rather than to try to get another mission.

If you give it good concentration, good energy, good heart and good performance, the song will play you.

We need to have a culture that says 'the less energy you can use to be comfortable, the better off you are and the better you should feel about yourself'.

I merely took the energy it takes to pout and wrote some blues.

I didn't know at the time that the energy that I was giving off was like a battle Emcee.

The young people look great on television. They're youthful and have a lot of zip and energy, but when you see them live, they can only do about 20 minutes because they haven't got the training to hold an audience for an hour and a half or so.

It takes a lot more energy to fail than to succeed, since it takes a lot of concentrated energy to hold on to beliefs that don't work.

I try to give positive energy in all my shows.

In modelling, there is no point in trying to prove you have a brain, so why even bother? I'd sooner save the energy for something more meaningful.

I was part of it, and I am still part of it today in terms of what it means to a whole new generation of people who are interested in the enduring energy, achievements, spirit and creativity that exemplified our era.

I always like having kid energy around. I think it's good for a movie, even when you're doing dramatic stuff.

You had to decompress the pressure before the race. I taught my heart to relax. I lay down before the race. It gave me more energy just before the race.

As long as I had easy access to psychedelics at the government-sponsored research project, most of my energy went into psychedelic sessions.

You can have anything you want if you want it desperately enough. You must want it with an inner exuberance that erupts through the skin and joins the energy that created the world.

Nerves provide me with energy... It's when I don't have them, when I feel at ease, that's when I get worried.

Electric cars aren't pollution-free; they have to get their energy from somewhere.

When I see someone who is starved, they don't look alert. They don't have boundless energy. If you're too skinny, it looks like you're near death.

Why is it so painful to watch a person sink? Because there is something unnatural in it, for nature demands personal progress, evolution, and every backward step means wasted energy.

Comedy is so hard; it's so much harder than drama. The pacing of it, the energy of it.

If for no other reason than the energy crisis now facing this country, the federal government should be eager to become partners with us in rebuilding our city.

It takes a lot of energy to teach.

Any long work in which poetry is persistent, be it epic or drama or narrative, is really a succession of separate poetic experiences governed into a related whole by an energy distinct from that which evoked them.

I believe that the average guy in the street will give up a great deal, if he really understands the cost of not giving it up. In fact, we may find that, while we're drastically cutting our energy consumption, we're actually raising our standard of living.

Life must be considered sui generis; it is not a form of energy, nor can it be expressed in terms of something else.

Men find it difficult because I've got so much energy and hardly sleep at night, only four or five hours. I wake up in the early hours and potter around.

It is greater than the stars - that moving procession of human energy; greater than the palpitating earth and the things growing thereon.

It is really hard to do comedy; it takes a lot of energy and focus. It's rather like music: It's a lot of hitting notes precisely.

Indeed, as the above calculation indicates, to take full advantage of the memory space available, the ultimate laptop must turn all its matter into energy.

The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light.

Maybe I'm being philosophical and spiritual, but I believe that if you put negative energy out there that that is what will come back.

The President's announcement sounded less like a national energy plan than like a page from an election-year play book. This Administration's plan to reduce obscene oil company profits is to regulate them less.
