    Unmanned probes from Earth can take from 7 months to two years to reach Mars, depending on when they are launched and how fast they can travel. The direct distance can vary from about 58 million kilometers to more than 400 million kilometers.


    The distance is at least 36 million miles (58 million km).
    So the minimum time would be:


    At 70 MPH -- 56 years
    At 500 MPH -- 8 years
    At Mach 1 (0.34 km/sec) -- 5.4 years (5 years, 5 months)
    At 40,000 MPH (fastest Voyager speed) -- 38 days


    Manned Missions
    The most commonly offered figure is "Six months there, and six months back". That is based on current (2012) by Text-Enhance" href="http://wiki.answers.com/Q/How_long_does_it_take_to_get_to_Mars_from_Earth">technology, and there are currently no solid plans for a manned flight to Mars. By the time man does inevitably make a manned flight to Mars, there may be newer technologies in space travel that shorten the travel time.
