## How much fuel does it take to fly to the moon and back?

Thanks to this and other advances, Falcon 9’s first stage uses 39,000 gallons of liquid oxygen and almost 25,000 gallons of kerosene, while the second stage uses 7,300 gallons of liquid oxygen and 4,600 gallons of kerosene. Combined, it makes lean mean 75,900 gallons of fuel.

How much fuel does it take to get a rocket in orbit around the Earth?

At liftoff, the two Solid Rocket Boosters consume 11,000 pounds of fuel per second. That’s two million times the rate at which fuel is burned by the average family car.

### How much fuel does a satellite need?

Geostationary satellites generally need about 50 meters per second of fuel per year to remain on station because the gravitational influence of the Sun and moon drag them away from their position over Earth. They’ll still be in a geostationary orbit, just not over the point on Earth where their operators wanted them.

How much fuel does it take to orbit?

You need to get to 8km/s to get into earth orbit. It takes another 6km/s worth of fuel (this is shorthand for the amount of fuel required to get from zero to 6km/s) to get to the moon, or another 8km/s to get to Mars.

#### How much rocket fuel is needed to reach the moon?

While the amount of fuel varied, depending on the mission, on average it used a total of 4,578,000 pounds (2,076,545 kg) of fuel. It could lift a payload to low Earth orbit weighing 310,000 lb (140,000 kg), and send a payload of 107,100 lb (48,600 kg) to the Moon.

How much rocket fuel do you need to go to the moon?

Rocket propellant, however, is a large resource mass that cannot be recaptured after use. Dynetics and SpaceX — two of the three providers of human landing systems — have indicated that between 30 and 100 metric tons of propellant may be needed for every return mission from the moon.

## How did they have enough fuel to get to the Moon?

Lift off. Stage One’s five rocket engines burned 20 tonnes of kerosene and hydrogen fuel per second to power Apollo to 42 miles above the Earth.

How much fuel does a Leo need?

An initial mass of 23 kg means 22 kg of fuel to get a 1 kg of payload on a zero mass rocket to LEO.

### How much thrust is needed to launch a rocket to lunar orbit?

What is needed is not thrust (above a certain basic amount), but delta-v, a function of the type of engine and the ratio between fueled mass and dry mass, according to the Tsiolkovsky equation. The required delta-v from low earth orbit to low lunar orbit is about 4040 meters per second.

How many gallons of fuel does a rocket hold?

All told, the rocket that achieved one small step for a man and one giant leap for mankind held just under 950,000 gallons of fuel. Since then, space-age technologies have come a long way.

#### What is an LEO satellite?

LEO – Low Earth Orbit One of the hot topics right now is the race to establish a network of Low Earth Orbit satellites. LEO satellites occupy the lowest orbit of all satellite types, often between 800 – 1,600 km (500 – 1,000 miles) above the surface.

What is the FMR ratio of the Space Shuttle?

This does not compare favorably with the Space Shuttle’s 5.8:1 overall ratio, but it does to the 17.08:1 ratio of the orbiter’s mass (including cargo) to the mass of the lift off stack. The actual FMR is nearer to 18.01:1, and assuming the light aeroshell mass (below) just under 37:1 per kilogram cargo put into LEO.
