Have you SEEN the price of gasoline lately....Just kidding-- Rockets fuels are rated by Specific Impulse, a measure of how fast the explosion travels when it shoots out the back. Gasoline is good as a fuel, but not as good as many others. The space shuttle uses hydrogen and oxygen.
I think I know what you're getting at... Rockets burn loads of fuel really quickly so we use jet engines in the atmosphere... The thing is that jet engines need oxygen to mix with fuel to burn it. Rocket engines contain their own oxygen which means that they are the most practical way for us to get into space.
A spacecraft need a rocket engine (which is powered by on-board oxygen and fuel) to propel itself, an airplane only needs a jet engine (which only needs on-board fuel as it uses oxygen form the air).
You can use the leftover gas to return safely to your spacestation
No. It is difficult and impractical to store anything as plasma. Some spacecraft use ion thrusters, which propel themselves with a jet of plasma, but the propellant is stored as ordinary gas or liquid.
The final quarter 2014, the average cost of jet fuel was about $2.85 per gallon. A Boeing 777 holds about 51,585 gallons of jet fuel.
$1.39
In the US on this day in April, 2011, a gallon of jet fuel purchased under a bulk contract costs about $3.25 per gallon.
Jet fuel weighs about 6.7 pounds per gallon and costs about 3 dollars per gallon, so that would equate to approximately 45 cents per pound.
Jet fuel weighs 6.8 lbs per gallon.
Jet fuel weighs about 6.7 pounds per gallon and costs about 3 dollars per gallon, so that would equate to approximately 45 cents per pound.
Jet fuel is diesel fuel, which is generally cheaper than high-octane gasoline.
The cost of jet fuel varies depending on the location of the airport and the city where its being purchased, this can cause a variation of a few dollars per gallon. It runs around $24 to $26 dollars a barrel.
Too much
Jet A fuel is roughly at 7.99 a gallon so your looking at about $457,707.15. That's to fuel up a 747 by the way. It depends on the plane
