If you want to go into space the first time on a new vehicle that's never been flown, you want to go with a pro.

I was born in 1960, and space theory, especially in the last part of that time and going into the '70s, space was very relevant at that time. It was on television - all the experiments, the moon...

NASA is not that sophisticated, they're not that organized, they're not that focused.

I would love to fly to the Moon or Mars.

Well, we spend an awful lot of our time working and doing experiments. It's very busy up on the shuttle.

The reason space missions need artificial gravity is clear: humans simply did not evolve to live in zero gravity.

The Chinese are planning a manned mission to the moon sometime after 2020, and subsequently, to Mars. The U.S. has abandoned that dream.

We were on the dark side of the Earth when we started to see outside the window this soft pink glow, which is a lot of little angry ions out there going very fast. We were hitting them very fast.

I always call myself a space construction worker.

After my spacewalks, I am quite exhilarated but also tired, similar to a workout on Planet Earth.

I was motivated to improve the U.S. strategy of going back to the moon in 1985. That's a long time ago. Going back to the moon would be a great achievement for tourism adventure flights.

When it comes to space, I see it as my job, I'm building infrastructure the hard way. I'm using my resources to put in place heavy lifting infrastructure so the next generation of people can have a...

Hubble orbits high, outside Earth's atmosphere so it can see a wide spectrum of light our atmosphere blocks.

Priorities have to be allocated by the government because they have a complete picture of the country's requirements. If priority is allocated to a manned space programme, I'm confident we can swing...

SpaceX is only 12 years old now. Between now and 2040, the company's lifespan will have tripled. If we have linear improvement in technology, as opposed to logarithmic, then we should have a...

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and...

Aviation - and space travel, in particular - have always been especially captivating.

The day is not far off when we will be able to send a robotically controlled genome - sequencing unit in a probe to other planets to read the DNA sequence of any alien microbe life that may be there.

By venturing into space, we improve life for everyone here on Earth - scientific advances and innovations that come from this kind of research create products we use in our daily lives.

Adaption of the human body in space is not yet mastered. As soon as you hit space, you feel your body is going through a period of mutation. There's no blood in your head; you have a hard time...

I could have gone on flying through space forever.

When we first get to space, we feel sick. Your body is really confused. You're dizzy. Your lunch is floating around in your belly because you're floating. What you see doesn't match what you feel, and...

We found out the Gemini spacesuit was, well, oxygen was flowing to keep me cool as well as to breathe, and it wasn't good enough. My visor got fogged.

Gravity disappears again, and we rise up off the floor like spooks from a grave. It's like the Rapture in here every thirty seconds.

Drinking coffee was one of the activities that didn't make the transition to microgravity well, but at half a g, it was fine.

The ocean, just outside, seeped into everything. An olfactory reminder to everyone passing through the Ellis Island of the space age that Earth was absolutely unique to the human race. The birthplace...

The thing Alex Kamal liked most about the long haul was how it changed the experience of time. The weeks - sometimes months - spent on the burn were like stepping out of history into some small,...

From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, "Look at that!" - EDGAR...

She'd headed the terraforming teams, and it was her leadership which had carried the task through to success. She and her people, watched over by Kau - yung's flagship, TFNS Gulliver, had battled the...

WELL, LADIES AND GENTLEMEN, the Stella Maris is on her way out of the solar system
