The civilization of Mars is 20-30 years after the first landing

In an exchange on Twitter Friday, Elon Musk, founder of SpaceX stated that humanity’s estimated timeframe to create a self-sustaining civilization on Mars is two to three decades before the first human landing.

“Mars may be a superior fixer of a planet, but it has great potential!” wrote the billionaire.

User @PPathole replied, asking Musk what he believed to be the “timeline for creating a self-sustaining civilization” there.

This is not the first time that the technology leader discussed the colonization of Mars – or the moon.

He previously touted the idea of ​​becoming a “multi-planet species”, building a city on Mars and sending one million people to the Red Planet by 2050.

Earlier this year, he hinted that a crewed mission to Mars could take place as early as 2029.

“Humanity will reach Mars in your lifetime,” he tweeted on July 6.

However, the feasibility or nobility of Elon Musk’s goals remains up for debate.
