I am the astronaut of boxing. Joe Louis and Dempsey were just jet pilots. I'm in a world of my own.
It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.
As a boy, because I was born and raised in Ohio, about 60 miles north of Dayton, the legends of the Wrights have been in my memories as long as I can remember.
This is one small step for a man, one giant leap for mankind.
We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.
Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind.
Astronauts have been stuck in low-Earth orbit, boldly going nowhere. American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that NASA's budget is too small for the job.
For the first time in my life I saw the horizon as a curved line. It was accentuated by a thin seam of dark blue light-our atmosphere. Obviously this was not the ocean of air I had been told it was so many times in my life. I was terrified by its fragile appearance.
Astronauts are inherently insane. And really noble.
At no time, when the astronauts were in space were they alone, there was a constant surveillance by UFOs.

So most astronauts getting ready to lift off are excited and very anxious and worried about that explosion - because if something goes wrong in the first seconds of launch, there's not very much you can do.

There weren't any astronauts until I was about 10. Yuri Gagarin went into space right around my 10th birthday.

The pressure suit helps if something goes wrong during launch or re-entry - astronauts have a way to parachute off the shuttle. The suits protect you from loss of pressure in case of emergency.
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.
I don't know any astronauts. There are a lot of people who say they want to be comedians.
I remember growing up thinking that astronauts and their job was the coolest thing you could possibly do... But I absolutely couldn't identify with the people who were astronauts. I thought they were movie stars.
