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.
How long does it take to travel to Mars? The first rover, Sojourner, landed on Mars in 1997. The second and third rovers, Spirit and Opportunity, were launched in 2003. All of the rovers travel very slowly so that they can take pictures and collect samples as they move.
