For the last several years and culminating in six months in orbit next year, I've been training for my third space flight. This one is almost in a category completely different than the previous two, specifically to live in on the space station for six months, to command a space ship and to fly a new rocket ship.

It's very expensive to be a professional tennis player with all the travel and the flights and the hotels and everything.

I love flying; I love aircraft, and you could say I've had a love affair with flight since I was a child. I travel a huge amount. I use airports, and as a pilot, I've flown in and out of airports thousands of times, so really, I have a fairly broad perspective.

My first ever job after college was as a flight attendant. I wanted to travel and could not afford it, so I decided to get myself a job where I could travel. I did it for two years and had great fun.

I like to bring some hydrating face oils and de-puffing eye patches in case I get puffy on the flight. I also always am sure to travel with my own silk eye mask; it's so necessary when trying to sleep on flights.

You define a good flight by negatives: you didn't get hijacked, you didn't crash, you didn't throw up, you weren't late, you weren't nauseated by the food. So you are grateful.

On long haul flights I always drink loads and loads of water and eat light and healthy food.

What other people may find in poetry or art museums, I find in the flight of a good drive.

Fifty years after humans landed on the moon for the first time, America has driven a golden spike on the trail to new space exploration feats through the work of our commercial partner SpaceX and all of the dedicated and talented flight controllers at NASA and our international partners.

I hope there will be continued U.K. investment in human spaceflight to enable Britain to benefit from space travel in the longer term and that many more Britons - women and men - will travel into space.

We collectively have a special place in our heart for the manned space flight program - Apollo nostalgia is one element, but that is only part of it. American culture worships explorers - look at the fame of Lewis and Clark, for example. The American people want to think of themselves as supporting exploration.

Most of my family and friends are very familiar with the human space flight program and with the excitement of becoming an astronaut.

One of the major problems with long-term deep space human flight is the requirement for radiation shielding.

Having a diverse suite of U.S.-manned spaceflight systems to access space is inherently robust.

I slept just floating in the middle of the flight deck, the upper deck of the space shuttle.

What I'm trying to do is, is to make a significant difference in space flight. And help make space flight accessible to almost anyone.

Manned spaceflight has lost its glamour - understandably so, because it hardly seems inspiring, 40 years after Apollo, for astronauts merely to circle the Earth in the space shuttle and the International Space Station.

The years of space flight since the orbiting of Sputnik I back in 1957 had produced many fascinating results, but they had also brought a realization of the many problems that surrounded the use of rockets for space flight.

I told them how excited I would be to go into space and how thrilled I was when Alan Shepard made his historic flight, and when John Kennedy announced on the news that the men had landed safely on the moon, and how jealous I was of those men.

I've always loved airplanes and flight. The space program was really important to me as a kid. I still have a photo of Armstrong and Aldrin on the moon in my living room.

I love the game of basketball. I guess it started with 'Space Jam.' Right after that movie, I went out there to my little Flight hoop and tried to do every dunk in the movie.

On flights, I cannot travel economy class, as I am too huge to fit into that space. I always have to travel business class.

A bird cannot fly with one wing only. Human space flight cannot develop any further without the active participation of women.

Why should man's first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction and expenditure?
