It was mentioned by Tesla & SpaceX CEO Elon Musk in a recent interview that his SpaceX project has plans to bring humans all the way to Mars in roughly 6-years in addition to an uncrewed space mission in 4-years.
Musk stated in the interview that he was “fairly confident” in the timeline he set and that it would be a Starship from SpaceX that would be launched into space. This would be based on the fact that both Mars and Earth have similar orbital patterns around the Sun, even though Mars’ orbit is more elliptical than Earth’s with relative orvits of roughly 26 months. At the next window, which appears to be in 2 years from now, SpaceX will be doing an uncrewed mission to Mars.
It’s Elon Musk’s belief that if he’s lucky, the first human landing on the moon may potentially happen in 4-years as opposed to 6-years at which point Earth’s and Mars’ orbits will be running parallel. Currently, Musk has the goal of ensuring that SpaceX has the proper tech in place in order to “make life interplanetary” via getting “a lot of people to go to Mars” alongside building “a base on the moon”.
