First you must figure out how close Mars can get to the earth.
It doesn't take years. The total journey time from Earth to Mars takes between 150-300 daysdepending 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.
686.971 Earth days.
It does no such thing. Mars orbits the sun. The only large object that orbits the Earth is the Moon.
Mars period of revoultion around the sun, its orbit, is 686.971 Earth days long. Earth takes 365.25 days.
22.2 minutes
First you must figure out how close Mars can get to the earth.
i saw on the History channel that it takes about 6 months each way
It would take nine months.
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

Because spacecraft don't travel in a straight line from Earth to Mars, as it would take too much energy. Instead they go on long eliptical transfers to meet up with where Mars will be at a later time.

It would take about 7 months to get to Mars
No spacecraft has been built yet that's capable of transporting human beingsto Mars, particularly if they're the kind of people who'd be expecting to breatheduring the trip, and to wrap it up some day by returning to earth alive.
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.
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.
