How long does it take a spacecraft to reach Mars?

aproximately about 2 yreas

It will take about 3 days, depending on the spacecraft.

At the fastest speeds of current spacecraft, it could take as little as a month or as long as a year. It would depend on the relative positions of the Earth and Mars. For comparison, the Mars Science Laboratory being launched in December 2011 should reach Mars 8 months later, in August of 2012.

it takes one year to get to mars

Mars is about 11 "light-minutes" from the Sun.

It took the Apollo 11 spacecraft three days to reach the moon.

Spacecraft launched from Earth to Mars usually take between 235 to 260 days , depending on the distance between the two planets on the launch date.

It depends on how far away Mars is at the moment. Mars varies from 36 million to 250 million miles from Earth, so at the speed of light (186,282 miles per second) it would take between 3.2 and 22.4 minutes for a radio transmission (of a picture, or whatever) to reach Earth from Mars.

It doesn't take 3 years. The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target.

i saw on the History channel that it takes about 6 months each way

it will take 1.5 times longer for light from the sun to get to mars than to get to earth

How long it takes a spacecraft to reach Mars depends on the changing distances between Mars and Earth as they orbit the sun, and other factors. Trips are usually planned for when Mars will be closest to Earth; the shortest is about three months. None of NASA's Space Shuttle fleet are capable of making the trip, and the remaining shuttles are due to be retired.

If you could accelerate steadily and constantly at 1 G for half the trip to Mars and then decelerate steadily at 1G, you could land on Mars in about 1 day, depending on where Mars was in its orbit. Unfortunately, no known spacecraft can accelerate at 1G for more than a few minutes at a time.

It takes about 3 days for a spacecraft to reach the moon. During that time a spacecraft travels about 240,000 miles (386,400 kilometers) which is the distance between Earth and the moon. It takes about 3 days for a spacecraft to reach the moon. During that time a spacecraft travels about 240,000 miles (386,400 kilometers) which is the distance between Earth and the moon.

About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)

because its a waste of resources and if there are aliens out there it would take to long to reach them

it could take you from 69 to 455 years depending on how far mars and earth are away from each other

254 days (approx.) to get to Mars, but a bit faster coming back to Earth as a spacecraft would be travelling into the gravitational pull of the Sun

Depending on the launch of the shuttle, it can take up to 300 days to get to Mars from Earth. It can be reached in as soon as 150 days.

It doesn't take years. The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target.

First you must figure out how close Mars can get to the earth.

nations: USA, USSR, E.U, possibly japan but im not entirtely sure on that. Time: variable, it depends on aat what point in the rotation the two planets are at (time of year), as well as any available gravitational boosts (moon, earth).

It took the Galileo spacecraft about six years to reach Jupiter from Earth.

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