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.
About 6 months. Minimal 104 days, typically you need about 180 days to Mars. If you only plan to stay on Mars for less than 1.5 years, you would need longer to Mars, as you have to use an Opposition-type transfer to Mars, instead of the more fuel-efficient Conjunction-type transfer. An Opposition type transfer takes place when Mars is on the opposite side of the sun, and uses a short swing around Venus to get home to Earth. This kind of mission takes minimal 104 days to Mars, but almost one year from Mars to Earth. It will take six months for the astronauts to get there. The ultimate mission, a manned mission to Mars, would most likely occur after 2030.
