How to Turn Water into Rocket Fuel - Scientists Unlock Power of the Sun
Let’s compare RP-1, hydrogen, methane, solid rocket fuel and even hydrazine-based hypergolic fuels. Going over these will pretty much cover the vast majority of rockets and what fuels they use. Let’s start off with the dirtiest of rocket propulsion, and that is solid rocket boosters. You...
How does registration work in a modern accordion? When is an analogy a weak analogy? Why wasn't Randall Stevens caught? Correct anonymization of submission using Latex How cheap would rocket fuel have to be to make Mars colonization feasible (according to Musk)? Starting with 2014 "+"...
NASA may use turbojets or air-augmented rockets to get the vehicle off the ground. An air-augmented rocket is like a normal rocket engine, except that when it gets a high enough speed, maybe at Mach two or three, it will augment the oxididation of the fuel with air in the atmosphere...
If you burn a pound of rocket fuel, a pound of exhaust comes out the nozzle in the form of a high-temperature, high-velocity gas. The form changes, but the mass does not. The burning process accelerates the mass. Let's learn more about thrust next. Thrust The "strength" of a ...
Consider how much coffee you drink if you're looking for a Rocket Espresso machine. Are you an occasional sipper or a multiple-cups-a-day person? This will help you pick a machine with the suitable capacity and features. Also, check the space in your kitchen or coffee nook. Rocket Espres...
Rocket engine: While a propeller engine uses the surrounding air as the working fluid of its propulsion, all a rocket needs is the thrust of its own combustion exhaust gas. This is why a rocket can provide thrust in space, but a propeller cannot. A rocket engine combines fuel and an inte...
"We certainly have predictions, but we'll know how much fuel is it releasing, how long does this take, are we going to be as successful as the analysis says?" said Lisa Watson-Morgan, who manages NASA's lunar landing program, in January. "We’re going to have to do this a ...
The primary concern of engineers is how to get a spacecraft to Mars, on the least amount of fuel. Robots don’t really care about the hostile environment of space, so it makes sense to decrease the launch costs of the rocket as much as possible. ...
“A spinning black hole is like a rocket on the launch pad,” said Biny Sebastian, a co-author from the University of Manitoba in Winnipeg, Canada. “Once material gets close enough, it’s like someone has fueled the rocket and hit the ‘launch’ button.” ...
