How long does it take for a rocket to get to Mars?

Answer 1

5 years ...no that's way off... It took the Mars Pheonix lander about 10 months to reach mars back in May 2008 and it takes light (or radio communication) about 10 minutes to travel that distance. It depends if you are using a constant boost ship or not. With a constant boost of 1 gravity, it would take about 2-3 days (you boost to the half way point then flip over and boost the opposite way to slow down). With a constant boost of 1/10 gravity it would take about 7-8 days. With a constant boost of 1/100 gravity it would take about 23 days. With a constant boost of 1/1000 gravity it would take about 73 days. This is the kind of boost you can achieve with "light sails" that use the "pressure" of the light coming from the sun. We are assuming that mars is about midway from the farthest it can be from the earth to the closest it can be from the earth. If mars is farther away it will take a little more and if mars is closer it will take a little less. Also it is interesting that light sail ships take only a little longer to reach Mars than it took the Mayflower to reach America. It took the Mayflower 66 days to reach America.

Answer 2

Depends how fast you are going. The folks at Universe Today, say 214 days, by a Hohmann Transfer Orbit. That means conserving your energy, using the momentum of the earth, and calculating the swing of the orbits, making sure that both planets are on the same side of the sun, to minimize the amount of energy that you use. That's with a chemical rocket. And you need to watch for your window of opportunity, which only opens up every two years or so. A plasma rocket, which can continue to accelerate for half the trip, might make it in 39 days. If you were riding a light beam, you could make it in four minutes, easy. [It only takes eight minutes for the light from the sun to reach the Earth, 93 million miles away.]

Just to give you a ball park on the distances, we on Earth are about 93 million miles from the sun; Mars, as a rough average, is about 143 million miles from the sun, I believe.

Answer 3

It would take about 214 days. And the only chance to launch would be once every 25 months because to conserve fuel rockets follow the Hohmann Transfer Orbit and that is once ever 25 months for mars. Check out "Related link" below.

Answer 4

it will take about 260 days to reach from mars to earth

Answer 5

It depends on how fast the rocket is traveling

Answer 6

dont ask me doofis

your the doofis. he asked the world. i think it takes 8 months. im most likely wrong though. try Google for your answer.this guy is mean i dont like him

Answer 7

At present it takes about 8 months, roughly.

Answer 8

approximately 214 days
