Rocket Fuel Quotes

If you think about the energy that a rocket engine has to put out and all the fuel and you're sitting on top of like a bomb. And on the Space Shuttle, that big orange tank is filled with liquid hydrogen and liquid oxygen, the white cell rocket boosters on the sides are filled with solid propellant. There's a lot of energy in all those chemicals there and you've got to control it in a way so it doesn't explode. So, there's a lot of plumbing, a lot of valving, a lot of control systems, and it's a very complicated thing. So, how do you bring the price of that down?

Rockets often spiral out of control if you put too much propellant in them.

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.

Stand back! I gotta get some rocket fuel out of the fridge!

Building and launching rockets has been a lifelong hobby that my son and I share. We regularly travel to Nevada's Black Rock Desert to launch rockets.

Apart from the obvious advantages of having ice to melt, filter, then drink, you can also break apart the water's hydrogen from its oxygen. Use the hydrogen and some of the oxygen as active ingredients in rocket fuel and keep the rest of the oxygen for breathing. And in your spare time between space missions, you can always go ice skating on the frozen lake created with the extracted water.

I realized that a methane-oxygen rocket engine could achieve a specific impulse greater than 380.

God,” I moaned. “Do they use that stuff as rocket fuel?” “No one made you keep drinking it.” “Hey, don’t get preachy. Besides, I had to be polite.” “Sure,” she said.

You need propellants to accelerate toward Mars, then to decelerate at Mars, again to re-accelerate from Mars to Earth, and finally to decelerate back at Earth. Accordingly, the mass of these required propellants, in short, drives our need for innovative launch vehicles.

Build a rocket ship and leave the earth!

When you launch in a rocket, you're not really flying that rocket. You're just sort of hanging on.

You can't ask your pharmacist to stock larger quantities of potassium nitrate because you want to make a bigger rocket.
