How many years to mars?

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 you're willing to burn to get there. More fuel, shorter travel time. read more

Every two years or so, Mars and Earth reach their closest point, called “opposition”, when Mars can be as close as 55,000,000 km from Earth. And every two years, space agencies take advantage of this orbital alignment to send spacecraft to the Red Planet. read more

In 2003, Mars made its closest approach to Earth in almost 60,000 years. The Hubble Space Telescope took the opportunity to observe the red planet while it was only 34,647,420 miles (55,757,930 km) from Earth. read more

The elliptical orbit which carries you from Earth to Mars is longer than Earth's orbit, but shorter than Mars' orbit. Accordingly, we can estimate the time it would take to complete this orbit by averaging the lengths of Earth's orbit and Mars' orbit. read more
