It truly is a privilege to work and to live here, and to be able to do both makes this just a really unique experience. And so as the only rookie in the group, it was really an honor to become a part of an expedition and see what it's like to fly the International Space Station.

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?

Consider what a romantic expedition you are on; take notes.

The negative cost of Lewis and Clark entering the Garden of Eden is that later expeditions regardless of what they were intended to do, later expeditions did not deal with the native peoples with the intelligence with the almost kindly resolve that Lewis and Clark did.

Writing a novel is not merely going on a shopping expedition across the border to an unreal land: it is hours and years spent in the factories, the streets, the cathedrals of the imagination.

I think the Lewis and Clark Expedition was the greatest undertaking in American History. I think landing a man on the moon pales next to it.

Good planning is important. I've also regarded a sense of humor as one of the most important things on a big expedition. When you're in a difficult or dangerous situation, or when you're depressed about the chances of success, someone who can make you laugh eases the tension.

The best climbers no longer go to the 8000ers, but to the most difficult mountains in the world which are 6000 or 7000-meter-peaks. There they find any kind of playground. But it is a pity that the really good climbers have fewer opportunities to finance their expeditions because so much attention is taken away by the Everest tourists.

EarthEcho Expeditions represents the culmination of more than a decade of working with educators and youth from around the world. EarthEcho Expeditions uses the thrill of adventure to inspire and empower a new generation of environmental champions.

With EarthEcho Expedition: Acid Apocalypse, we are working with youth leaders and noted experts on the changing chemistry of our ocean to help illuminate one of our most pressing and inscrutable environmental issues.

A life lesson for me is, how do you muster the courage to take on a new risk? Whether it's starting up a business or taking on a new project or expedition. I think the risks that we take are all relative to the risk-taker.

When I was a kid, I was reliably informed that we'd have gone to Mars by 1985, and of course it's 2012, and we're still really no closer to a human expedition to Mars, but that shouldn't detract from the amazing achievements that are being done on a day-to-day basis by robotic envoys.

Life is not a quest. It's a voyage of discovery. An expedition through yourself and life.

It is sweet to think I was a companion in an expedition that never ends

Only philosophers embark on this perilous expedition to the outermost reaches of language and existence. Some of them fall off, but others cling on desperately and yell at the people nestling deep in the snug softness, stuffing themselves with delicious food and drink. 'Ladies and Gentlemen,' they yell, 'we are floating in space!' But none of the people down there care

Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions but you really climb for the hell of it.
