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.
What struck me most was the silence. It was a great silence, unlike any I have encountered on Earth, so vast and deep that I began to hear my own body: my heart beating, my blood vessels pulsing, even the rustle of my muscles moving over each other seemed audible. There were more stars in the sky than I had expected. The sky was deep black, yet at the same time bright with sunlight.
I have been privileged to be briefed and to know that we have been visited [by aliens]. I do not have first hand experience in this regard, but I have been on investigating teams and I have been briefed by insiders who do know.
On the return trip home, gazing through 240,000 miles of space toward the stars and the planet from which I had come, I suddenly experienced the universe as intelligent, loving, harmonious.
Don't get bogged down by the notion of limits. There aren't any.
I think humans will reach Mars, and I would like to see it happen in my lifetime.
Something I'll always remember - when I was a kid, I shook hands with Orville Wright. Forty years later, I shook hands with Neil Armstrong. The guy that invented the airplane and the guy that walked on the moon. In a lifetime, that's kinda wild when you think about it.
Neil Armstrong today takes his place in the hall of heroes. The moon will miss its first son of earth.
Before you can make a dream come true, you must first have one.
Different astronauts sleep in different ways.
The quiet that envelops space makes the beauty even more powerful, and I only hope that the quiet can one day spread to my country.
We must move into the universe. Mankind must save itself. We must escape the danger of war and politics. We must become astronauts and go out into the universe and discover the God in ourselves.
And, so I set my goals on astronaut because, as a military aviator, it was, I considered that to be about the peak of a flying career.
Decide in your heart of hearts what really excites and challenges you, and start moving your life in that direction. Every decision you make, from what you eat to what you do with your time tonight, turns you into who you are tomorrow, and the day after that. Look at who you want to be, and start sculpting yourself into that person. You may not get exactly where you thought you'd be, but you will be doing things that suit you in a profession you believe in. Don't let life randomly kick you into the adult you don't want to become.
If we die, we want people to accept it. We are in a risky business, and we hope that if anything happens to us, it will not delay the program. The conquest of space is worth the risk of life.
Every generation has the obligation to free men's minds for a look at new worlds . . . to look out from a higher plateau than the last generation.
My mental boundaries expanded when I viewed the Earth against a black and uninviting vacuum, yet my country's rich traditions had conditioned me to look beyond man-made boundaries and prejudices. One does not have to undertake a space flight to come by this feeling.
As I hurtled through space, one thought kept crossing my mind - every part of this rocket was supplied by the lowest bidder.

There are people who make things happen, there are people who watch things happen, and there are people who wonder what happened. To be successful, you need to be a person who makes things happen.
I was born too late for steam trains and a lazy eye meant I'd never be an astronaut.
I wanted to be a secret agent and an astronaut, preferably at the same time.
The world looks marvelous from up here, so peaceful, so wonderful and so fragile. Everybody, all of us down there, not only in Israel, have to keep it clean and good.
