“First crewed mission would have about a dozen people, as the goal will be to build out and troubleshoot the propellant plant and Mars Base Alpha power system.”

What actually happened

Fetched Oct 6 2026: Wikipedia still records Musk's 2016 ~12-person first-crewed-Mars architecture and the Feb 2026 delay of Mars ambitions ~5–7 years toward the Moon. No crewed Mars mission has flown; Starship remains uncrewed through Flight 14 (first orbit Sep 28). Deadline 2029. Status stays pending.

In an October 2016 Reddit AMA, Musk said the first crewed Mars mission would carry about a dozen people, tasked with building out and troubleshooting the propellant plant and the Mars Base Alpha power system. The crew-size detail makes this one of his more specific Mars architecture claims. It is tracked against a 2029 deadline and remains pending.
