How long does it take to travel to Mars? The trip takes around seven months; a bit longer than astronauts currently stay on the International Space Station. The precise duration of each journey depends on when it is taken. Because both Mars and Earth's orbits are not perfectly circular, the time it takes to travel between them varies from six to eight months.
