The amount of fuel required to take astronauts to Mars depends on the number of astronauts, the amount of equipment they take with them, and whether the designers want the trip to take a short time (requires more fuel) or a long time (requires less fuel but more supplies). It also depends on the propulsion system to be used. The actual amount of fuel needed has to be determined during the design process and cannot be estimated in advance.

∙ 11y agoIt's difficult to give a meaningful general answer, because it depends on the precise details of the trajectory and the payload.
To put it into perspective, the Mars Science Laboratory had a payload of a little under 4 tons, and the total mass of the fueled launch vehicle was about 531 tons. Part of that was the launch vehicle itself, but for a rough ballpark figure, in that particular launch the ratio of fuel to payload delivered to Mars was over 100:1, and it will take a little over 8 months to get there.
Using those figures a 70-kg astronaut would need more than 7 tons of fuel to get him to Mars naked. He'd also need food, water, air, and protective clothing/equipment for an 8 month journey plus however long we wanted him to live after he reached Mars, and each pound of that is subject to the same 100:1 ratio. You can see how this quickly becomes prohibitive, and why we're sending robot probes instead.
Another benefit of robot probes is that there are no... well, few, see the related links... ethical concerns about not bringing them back. A return journey would need additional food, water, and air, along with (most critically) additional fuel. It wouldn't take as much fuel to get back as it did to go in the first place, but whatever fuel it did take, multiply that by 100 again to obtain the amount of launch fuel needed to get the return fuel to Mars.

How long does it take to get from earth to moon in a rocket?
The 747-400, the latest version in service, is among the fastest airliners in service with ahigh-subsonic cruise speed of Mach 0.85 (567 mph or 913 km/h).If it were possible to fly one of them to the moon, travel in a straight line, and maintainthat speed, the trip would last 421.5 hours (17days 13hours 31minutes) of continuous flight.

If you ever go to the moon and you need to eat food where would it come from?
If you ever go to the moon, you need to take food with you from the earth. You also need to take water and air with you, and anything else you think you'll need on the moon. Scientists are pretty sure that there is nothing to eat, drink or breathe on the moon, or anything else that people need in order to live. Just a bunch of rocks and dust. Astronomers on the earth have never seen anything else on the moon with their telescopes, and the astronauts who landed on the moon never found anything else there.

How does a rocket change its speed in space with no air?
Some people (who have not studied physics) believe that rockets work because the rocket exhaust pushes against the air, and therefore in the vacuum of space where there is no air, rockets won't work - but that is not the case. Rocket exhaust doesn't need to have air to push against. The expanding gases in the rocket's exhaust nozzle push against the rocket. The gas has its own mass and its own inertia, and the change in momentum of the exhaust gas causes an opposite change in momentum of the rocket. This can be difficult to grasp because we think of gas as being virtually weightless, but a large rocket can emit literally tons of exhaust. The fact that it is in the form of a gas doesn't change the result; mass is mass, whether solid, liquid, or gas.This is WRONG, rocket DOES work in space.From NASA"A rocket is a type of engine that pushes itself forward or upward by producing thrust. Unlike a jet engine, which draws in outside air, a rocket engine uses only the substances carried within it. As a result, a rocket can operate in outer space, where there is almost no air."How it accelerate"Rocket engines generate thrust by putting a gas under pressure. The pressure forces the gas out the end of the rocket. The gas escaping the rocket is called exhaust. As it escapes, the exhaust produces thrust according to the laws of motion developed by the English scientist Isaac Newton. Newton's third law of motion states that for every action, there is an equal and opposite reaction. Thus, as the rocket pushes the exhaust backward, the exhaust pushes the rocket forward.The amount of thrust produced by a rocket depends on the momentum of the exhaust -- that is, its total amount of motion. The exhaust's momentum equals its mass (amount of matter) multiplied by the speed at which it exits the rocket. The more momentum the exhaust has, the more thrust the rocket produces. Engineers can therefore increase a rocket's thrust by increasing the mass of exhaust it produces. Alternately, they can increase the thrust by increasing the speed at which the exhaust leaves the rocket."http://www.nasa.gov/worldbook/index.html

How much fuel will be needed in a rocket?
How much fuel will be needed in a rocket will depend on the size of the rocket and where it is going. A rocket that will be traveling into space burns a lot of fuel and will need enough to keep it in orbit for teh desired time.
How do you get extra fuel on astro knights?
If you mean for the original ship powered by the fuel rod, you never need to replace it. You will crash on the moon and you will make a new rocket for your travels. And if you run out of shields with the rocket, you will automatically be teleported to the moon and the shields will be replenished.
How much fire power do you need to send a rocket to the moon?
It depends on the size, weight and shape of the rocket, but the amount of fuel used in NASA rockets is about 1000 tons of fuel per launch. The combined thrusting force required is around 25,000,000 N.
Why does rocket taking off from the earth needs much more fuel than the same rocket taking off from the moon?
dunno and it need answer gravity is very strong on earth as the rocket gets higher gravity gets weaker they have to overpower gravity to lift of
How much fuel did Apollo 13 need to get to the moon?
Apollo 13 never made it to the moon, suffering a catastrophic failure en route. The Apollo missions in general used 5.625 million pounds of fuel in all three four stages of the Saturn V rocket.
How much rocket fuel do you need to get into space?
It depends on the weight of the rocket and payload. The Saturn 5 that carried the Apollo moon missions into space carried 5.5 million pounds (2.5 million kilograms) of fuel. Most of the fuel is used to lift the fuel.
How much fool is needed to get to the moon and how much does it weigh?
Assuming you meant Fuel (not food which cannot answer due to too many variables) the answer is also hard to answer.However as an example - which explains the major point - That you need A LOT of it might help.When we were going to the moon in the 60s and 70s we required almost 100 lbs of fuel for every pound sent to the moon. Take a look at the rockets used. That little cap on the top of the rocket was the spaceship. 90% plus of the rocket was boosters and fuel! Almost all of it used up just to get 300 miles up out of the Earths gravity.
What type of fuel does the space shuttle need?
It uses rocket fuel
Why do space probes go to space?
Since we can't get human beings past the moon, we need space probes to explore past the moon. We don't have the technology and fuel to build a rocket that travels that far.
What is the impact on people for discovery of water in moon?
The main reason we would like to find water on the moon is that we will not have to bring it from earth.Water can be used as rock fuel if you separate the two components: Hydrogen and Oxygen. If water is present on the moon, we can create our own rocket fuel on the moon when we explore the rest of the solar system and beyond.Water on the moon is of course not only important for rocket fuel. If we in future wish to set up a base on the moon, the people living there will need water to drink and to irrigate the plants (for growing food in greenhouses). We do not need to bring this water if water already exists on the moon.Leaving earth's gravity is difficult and require a lot of energy (e.g. expensive in terms of fuel costs). Water is relatively heavy (and take up a lot of room). To lift it past earth's gravity is very taxing. It is much easier to escape the moon's gravity due to the lower gravitational pull.If we can find water on the moon, we do not need to bring it from earth.
