Musk—who has a history of setting unrealized goals for his companies—says he wants to send humans to Mars by 2029, though he says 2031 may be more likely.

Under SpaceX CEO Elon Musk's vision, humans could then land on the Red Planet in 2029, though he admitted 2031 is "more likely."

Elon Musk boldly claimed he could land humans on Mars "as soon as 2029." "Starship departs for Mars at the end of next year, carrying Optimus," the SpaceX CEO wrote in an X post shared on Saturday, referring to the space technology company's launch vehicle and Tesla's robot.
