Quotes About Propulsion

Astronautics, strictly speaking, will be concerned with voyages to other stars. Remarkably enough, to achieve such feats, we might not even have to leave the earth. It would suffice to accelerate the sun itself to a very high speed and let it drag all its planets with it.

The walking of Man is falling forwards.

He tried to explain how there was something cathartic about being in the water. You stared down at the thick black line scrolling steadily beneath you, and all you heard was the rush of water past your ears, and a life that at times felt cosmically complicated was reduced to the simplest elements: oxygen, buoyancy, propulsion.

I need, sometimes, individuals to spark an idea so that I can take off running.

It's easy to reckon that the oomph to hurl even a Smart Car-size spacecraft to another star at, say, 20 percent the speed of light (and land it when it arrives) is the energy contained in 50 billion gallons of gasoline. The tank's not big enough.

There are ecological, biological, sociological, and psychological problems that can never be solved to make this idea work. The physical problems of propulsion have capture your fancy, and perhaps they can be solved, but they are the easy ones.

You know what I like about driving? The forward motion of it, the propulsion of it, like you might go anywhere.

Chemical propulsion is obsolete to go anywhere other than the moon. Three days - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then spend whatever length of time we want to spend and return when we want to come home.

Emerging Possibilities for Space Propulsion Breakthroughs, and it had first appeared in a NASA publication, Interstellar Propulsion Society Newsletter, in July of 1995.

Good with tools," Herr Siedler is saying. "Smart beyond your years. There are places for a boy like you. General Heissmeyer's schools. Best of the best. Teach the mechanical sciences too. Code breaking, rocket propulsion, all the latest.

The wings are moved several times by hand to charge the crank chamber with mixture, which flows on through the external pipe and inlet valve to the compression space and cylinder.

Gentlemen, I give you the Whittle engine.

On Sunday August 5, 2012, I was among a group of people who witnessed the Rover landing on Mars in real time at NASA's Caltech-managed Jet Propulsion Laboratory in Pasadena.

If you stop and think about it, the form of propulsion used today hasn't changed in over a thousand years... since the invention of fireworks by the Chinese.

You don't just throw the ball - you propel it.

This was the fundamental problem with rockets—and no one had ever discovered any alternative for deep-space propulsion. It was just as difficult to lose speed as to acquire it, and carrying the necessary propellant for deceleration did not merely double the difficulty of a mission; it squared it.

Many scientists flatly denied the possibility. They pointed out that Discovery, the fastest ship ever designed, would take twenty thousand years to reach Alpha Centauri — and millions of years to travel any appreciable distance across the Galaxy. Even if, during the centuries to come, propulsion systems improved out of all recognition, in the end they would meet the impassable barrier of the speed of light, which no material object could exceed.

A bird's wing, comrades,' he said, 'is an organ of propulsion and not of manipulation. It should therefore be regarded as a leg. The distinguishing mark of man is the hand, the instrument with which he does all his mischief.

It has seemed to me that if I had the genius to found the jet propulsion field in the US, and found a multimillion dollar corporation and a world renowned research laboratory, then I should also be able to apply this genius in the magical field.

Imagination is the propulsion of Life once we exhaust all reality.

The Air Corps . . . does not, at this time, feel justified in obligating . . . funds for basic jet propulsion research and experimentation.

I don't know, I thought it sounded good?" Actually, I was really proud of the unexpected change of key and rhythm, especially because it gave the song, and the scene, a sense of propulsion. "Well, I wouldn't have done that." Which is when I decided never to play him my music again.

up the engines of all of them and began

Rocket engines generally are simpler than jet engines, not more complicated.
