How many gallons of fuel would it take to go to mars and back?

The exact amount of fuel needed to travel to Mars and back would depend on the spacecraft design, propulsion system, and mission profile. Estimates suggest that a round trip to Mars would require tens of thousands of gallons of fuel due to the large distance and complex orbital dynamics involved in such a mission.


How much water do you need to go to mars and back?

It is estimated that around 24,000 liters of water per person would be needed for a round-trip journey to Mars, factoring in drinking, hygiene, and food preparation requirements. This amount would need to be recycled efficiently to sustain the mission.


Why would getting back from mars be a problem?

Getting back from Mars poses numerous challenges, including the risks associated with landing on Earth after a long journey through space, potential health issues from extended exposure to space radiation and reduced gravity, and the need for precise timing and navigation during re-entry into Earth's atmosphere. Additionally, the logistics of launching a return mission from Mars, including the availability of fuel and resources, further complicate the process.


How would a spacecraft have enough fuel to leave mars?

A spacecraft leaving Mars would need to carry enough fuel to achieve escape velocity from the planet's gravity well. This fuel would typically be carried on board the spacecraft in the form of liquid or solid propellant, either in the main propulsion system or in auxiliary thrusters. The amount of fuel required would depend on the spacecraft's mass, the desired trajectory, and the efficiency of the propulsion system.


Are scientists trying to figure out how to make people live on mars?

The moon landings proved that we have the means to live on other planets (including Mars). What we need is a way to get the necessary supplies (food, oxygen, water, etc) to send people to mars and bring them back to earth.

What else do we need to know about mars for humans to go there?

if there is water if it is at the right temperature how long it would take us to get their how much fuel we would need in a rocket to get to mars are their any aliens or harmful animal their is their enough oxygen etc.


Which vehicules could be used on mars?

We would need to use battery charged cars because if we use the cars that run on fuel we would be pulluting the planet mars.


Why would an astronaut on mars need a spacesuit the mystery of mars story a?

Well first they would need it for oxygen saying that there isn't much if at all on Mars, they would also need one to prtect them from the deadly radiation.


Did Mars Rovers come back to earth?

It doesn't. It radios its data back to Earth. there is no need for the actual rover to come back. Nothing should be brought back from Mars unless it is proven lifeless, as Martian life may be dangerous to Earth life, like us!


Where is the fuel pump on a 2000 olds intrigue?

It's in the gas tank. If you need to change it, Google it or get a pro to do it. Fumes are dangerous. You can access it from the trunk under the carpet, near the back seat. Good luck Mars


When should you turn on a PWC's fuel selector switch to reserve?

1) When you run out of fuel and need to get back to a dock. 2) When you have a fuel flow problem and suspect the pickup or fuel selector might be clogged and need to get back to a dock.

How much fuel does an airplane need?

they need a lot alot of fuel1


How much fuel does a rocket need to fly to the moon?

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.


How much fuel does a aeroplane need?

That depends on how much it consumes, and how far it is going.
