The average amount of time it would take to reach Mars is 162 days, but the reality is different because the craft cannot pass through the sun. Accurate times require knowledge of fuel requirements and complex gravitational equations.
The proposed NASA manned mission estimates about 200 days to reach Mars and 200 days to return. But one trip would take much longer unless the mission stayed on Mars for a year until the planets were again lined up in relation to their orbits. The actual yearly minimum distance is from 60 to 100 million kilometers. 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.
