Zitat des Tages von Buzz Aldrin:
What's aero braking? That's a way to use the gravity and upper atmosphere of Earth to sling shot a ship out either deeper into space, or slow it down to be 'captured' by Earth's gravity.
There's a need for accepting responsibility - for a person's life and making choices that are not just ones for immediate short-term comfort. You need to make an investment, and the investment is in health and education.
'Anthony and the Magic Picture Frame' tells it like it really was in America's early space program - the adventure, the risks, and the rewards.
NASA's been one of the most successful public investments in motivating students to do well and achieve all they can achieve, and it's sad that we are turning the program in a direction where it will reduce the amount of motivation it provides to young people.
I wrote 'Reaching for the Moon' because I wanted to tell kids that all of us have a moon, a dream, that we can strive for. Even if you don't attain it, you can at least reach for it.
To move forward, what's required is a unified space agenda based on exploration, science, development, commerce, and security.
When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.
As we begin to have landings on the moon, we can alternate those with vertical launch of similar crew modules on similar launch vehicles for vertical-launch tourism in space, if you want to call it that... adventure travel.
It's real easy to manufacture what you think the people want to hear. But that's not very honest.
When we can demonstrate that we can take off horizontally and put something into orbit, then we can begin to talk about increasing the amount of payload. But to say, 'I'm going to do that and put people into orbit' is a real leap.
We must still think of ourselves as pioneers to understand the importance of space.
I shot down two airplanes in Korea, so I wasn't a slouch.
Not everyone will understand this need for America to lead the world in space.
In Mars, we've been given a wonderful set of moons... where we can send continuous numbers of people.
Globalisation means many other countries are asserting themselves and trying to take over leadership. Please don't ask Americans to let others assume the leadership of human exploration. We can do wonderful science on the Moon, and wonderful commercial things. Then we can pack up and move on to Mars.
To me, money is a commodity that a person must have to function, not a goal in itself.
Fighter pilots have ice in their veins. They don't have emotions. They think, anticipate. They know that fear and other concerns cloud your mind from what's going on and what you should be involved in.
Instead of planning the retirement of the Space Shuttle program, America should be preparing the shuttles for their next step in space: evolving, not shutting them down and laying off thousands of people.
My favourite thing to do on this planet is to scuba dive.
I'm urging NASA to foster the development of what I call 'runway landers.' No, that's not the name of a high stakes gambler from Vegas. It's a type of spacecraft that flies to orbit like the retiring Shuttles but then glides to a landing like an airplane on a runway. Just like the Shuttles do.
You can never tell when a commercial space venture will suddenly become viable.
Landing in the ocean and waiting for the Navy to come alongside and haul you out of the drink is what space capsules require. And after the capsule is recovered, it would take weeks for the ship to return to port.
It was interesting to think that the very first liquid ever poured on the Moon, and the first food eaten there, were communion elements.
Tang sucks.
If you want poets in space, you'll have to wait.
I want people to go into space, to orbit around the world a few times, even to stay there for 24 hours and then come back to where they took off. And I also want people with a low income to be able to do that, not only rich people.
I didn't start skiing until I was 50. My wife Lois taught me how to ski. I'm proficiently conservative.
Every couple of years, we could dispatch people from Earth to Mars.
I realize that my life is not the common ordinary person.
Unfortunately, kids are led to believe things are easier to achieve than they really are.
I was the first Navy, Marine or Air Force person who had been an astronaut to return back to the Air Force. I had certain expectations about what would be a reasonable and desirable position to be assigned to after my years of service.
I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.
Over the years, I think I've matured in my spiritual evolution and development to understand a bit more than the narrow religious thinking - to move beyond that through a sort of perfection of the grandiose nature of the universe, and how perfect it is it in its sense and how satisfied we should all be in our place in that.
As we reflect back upon the tragic loss of Challenger and her brave crew of heroes who were aboard that fateful day, I am reminded that they truly represented the best of us, as they climbed aloft on a plume of propellant gasses, reaching for the stars, to inspire us who were Earthbound.
With his deeds, not only words, President Obama has revitalized our struggling space program.
The society of life on Mars, or the challenge of making Mars more livable, will have significant benefits on our attempts to modify and change in some ways the environment here on Earth.
