Elon Musk says SpaceX will set humans on Mars in just 4 years

Elon Musk says SpaceX will set humans on Mars in just 4 years — and he says there’s nothing more important than this.

“The important thing is that we build a self-sustaining city on Mars as quickly as possible,” he said this week during an interview with Senator Ted Cruz and Ben Ferguson on the Verdict with Ted Cruz podcast.

Musk continued by noting that he believed it will only take another 15 years after that to make the planet sustainable for one million people to live there claiming, “I think it can be done in 20 years”.

Do you agree or disagree with Musk?

His full quote reads:
“The important thing is that we build a self-sustaining city on Mars as quickly as possible. The key threshold is when that city can continue to grow, continue to prosper, even when the supply ships from Earth stop coming at that point, even if something would happen on Earth. It might not be World War III – civilisation could die with a bang or a whimper. So you obviously need Mars to become self-sustaining and be able to grow by itself before the resupply ships from Earth stop coming. That is the critical civilisational threshold beyond which the probable lifespan of civilisation is much greater.

We’re here at the top of a massive pyramid of industry [on Earth]. That starts with mining a vast array of materials (and) those materials going through hundreds of septs of refinement. We grow food obviously, we grow trees, we make things out of the threes, you’ve got to build all of that on Mars.

And Mars is a hostile environment, it sometimes gets above zero on a warm summer day near the equator on Mars, really it’s quite cold.”
