Every 26 months the planets align in such a way that it is ideal to send spaceships to Mars.
Therefore, SpaceX is aiming to send their first spaceships to Mars as soon as 2022.
One of the goals for this trip will be to see if they are able to launch a rocket from Earth and then refuel it in orbit using a second rocket.

If they’re able to successfully land on Mars, the spaceship will drop off some cargo that will be used by the first Martians arriving just a few years later.
This first Starship will probably stay on Mars, for the first Martian to use as resources when they arrive.
