IAC 2016 — Making Humans a Multi-Planetary Species
About this appearance
The most consequential SpaceX keynote ever delivered. In Guadalajara, Musk unveiled the Interplanetary Transport System (ITS) — the predecessor to Starship — with enough technical detail to be credible. He laid out the full economic and engineering case for a self-sustaining Mars colony: 1 million people, 1,000 ships, in-situ resource utilization, refueling in Mars orbit. He addressed safety, timelines, and cost directly. The phrase 'making humanity a multi-planetary species' entered the cultural vocabulary. The auditorium packed with aerospace engineers gave a standing ovation.

States a Mars ticket should eventually cost around $200,000 — 'roughly the cost of a house in the US' — making colonization accessible to middle class.
Describes potential for in-situ methane production on Mars, enabling a fully reusable two-way trip: 'You could come back.'
Key quotes
“In order to have a self-sustaining city on Mars, you need on the order of a million people. And you need the resources to build a city. And rockets. A lot of rockets.”
