CancelledUncrewed Mars landing 2018
“Planning to send Dragon to Mars as soon as 2018. Red Dragons will inform overall Mars architecture, details…”
“Well, we're going all the way to Mars, I think — best case 10 years, worst case 15 to 20 years.”

What actually happened
The best-case 10-year mark passed in April 2021 with no human having traveled beyond low-Earth orbit since 1972, let alone to Mars. Fifteen years on (2026), still no crewed Mars mission exists or is scheduled: in September 2024 Musk re-baselined to uncrewed Starships in the late-2026 window with crewed flights about four years after that — putting his own new best case at roughly 2028-2031, the tail end of his 2011 worst case.

In an April 2011 Wall Street Journal interview, a year after Falcon 9's first flight and before Dragon had ever carried cargo to the ISS, Musk said SpaceX would put a person on Mars in 10 years best case, 15 to 20 worst case. It is the earliest widely-circulated version of the Mars timeline he has restated and slipped ever since — by 2024 his own best case had moved to roughly 2028-2031.
