how much fuel would it take to get to mars?

In India's Mars mission, it took a launch vehicle called PSLV-C25, measuring 145 feet long and carrying over 200 tons of propellant fuel. That's less than half the fuel a space shuttle mission routinely carried. In terms of weight, it's slightly less than 1 percent of the fuel the US Air Force uses in a day.

In fact: If you could walk from Earth to Mars at a brisk rate (about five miles per hour) it would take about 4,000 years to reach the Red Planet. If you drove a car 70 mph, it would take 228 years. If you had a 747 airlane, it would still take 32 years.

When it burns, it turns into lots of carbon dioxide gas. Gasoline is mostly carbon by weight, so a gallon of gas might release 5 to 6 pounds (2.5 kg) of carbon into the atmosphere. The U.S. is releasing roughly 2 billion pounds of carbon into the atmosphere each day.

The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.

With our current technology, it's estimated it'll take humans around five months to reach Mars. But NASA scientist Philip Lubin is working on a system where lasers propel spacecraft with giant sails to the Red Planet in as little as three days.

Quick Summary: Mars is relatively small, having only about 10% the mass of the Earth. Mars has an atmosphere made up mostly of Carbon Dioxide but its pressure is only 1% of the Earth's atmospheric pressure. Thus Mars has 10,000 times less Carbon Dioxide in its atmosphere than Venus.

It takes roughly the equivalent of 260 gallons of gasoline to make the typical car of around 3,000 pounds, according to an exhaustive study by the Argonne National Laboratory. (And I do mean exhaustive. These guys have factored in darn near everything but the calories consumed by the assembly-line workers.)

If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour.

VFR Fuel requirements (airplanes and helicopters): Day: You need enough fuel to fly to your first landing point and then still have 30 minutes of fuel remaining at a normal cruise speed. Night: Same as above, but you need 45 minutes after reaching your first point.

So distance between Earth and Mars can be easily obtained by simple subtraction. On average we are 225 million kms apart. 54 million kms on closest, 401 million km on farthest .

To travel a distance of 800 km a car requires 24 liters of fuel.

Hence, you would weigh about 75.88 pounds (or 75 pounds and 14 ounces) on Mars.

In total, the four rovers that have already gone to Mars are: Sojourner, Spirit and Opportunity, and Curiosity. The Perseverance rover will be heading to the Red Planet soon.

See NASA's big plans for its new Mars rover, Perseverance (CNN) The NASA Perseverance rover has been confirmed to be healthy and is now on a journey to Mars. It will take between 6.5 and seven months before the rover lands on the red planet in February 2021.

Many space agencies have taken advantage of this orbital alignment and sent many spacecraft to Mars. The journey usually takes between 150 to 300 days, depending on the speed of the launch, the alignment, and the length of the trip.

The results SAM spit out confirmed the makeup of the Martian atmosphere at the surface: 95% by volume of carbon dioxide (CO2), 2.6% molecular nitrogen (N2), 1.9% argon (Ar), 0.16% molecular oxygen (O2), and 0.06% carbon monoxide (CO).

The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. ... Oxygen: 0.13 percent. Carbon monoxide: 0.08 percent. Also, minor amounts of: water, nitrogen oxide, neon, hydrogen-deuterium-oxygen, krypton and xenon.
