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. It really just depends on how much fuel youâre willing to burn to get there. More fuel, shorter travel time.
Obviously, if you want to travel to Mars, it would be best to do so at the point of opposition, when Mars is âonly 35-63 million miles away. That is why rocket scientists time their unmanned missions to Mars to coincide with opposition windows every 26 months. The most recent opposition window was in May 2016 and the next one will be in 2018. If you dream of one day being an astronaut on the first manned flight to Mars, be prepared for a long trip. Scientists estimate a trip to Mars and back would take 400-450 days.
