"Terraforming will be too slow to be relevant in our lifetime", Musk wrote in another tweet.
As Tech Times earlier reported, SpaceX is getting ready for Starship's orbital test flights in 2021, and if all goes well according to schedule, the first Starship en route to Mars will be launched as early as 2024. However, we can establish a human base their in our lifetime. The 49-year-old businessman said that within his lifetime, humans might develop into a spacefaring civilization, discovering old generation's ruins.
And after bombs are dropped and Mars is habitable, Musk plans to send one million people to live on Mars - which he says will happen by 2050.
Last month, SpaceX also discussed what life might look like when man finally manages to land on the Red Planet.
This statement falls in line with wording in Starlink's beta consumer service term.
Buried in the text is a section titled 'Governing Laws, ' which states SpaceX will not abide by global laws beyond Earth and the moon, but instead adopt self-governing principles 'established on good faith'.
Musk has taken it upon himself to declare Mars a 'free planet'.
"Accordingly, disputes will be settled through self-governing principles, established in good faith, at the time of the Martian settlement".
However, the Hawthorne, California-based is still developing the rocket's interior and cabin for passengers, so Musk declined to go further into the details as they are still focused on making the Starship work first.
Earlier this year, Mr Musk said Starship was the firm's "top priority", writing in a company-wide email that progress needed to speed up "dramatically and immediately" in order to meet the ambitious target of sending the first humans to Mars before 2030.
"And I think the probability of it being created after World War 3 - hopefully there's never a World War 3 - but the probability of after is low, so we should try and make the city self-sustaining before any possible World War 3".
However, more than transporting humans, Musk is more concerned of building a self-sustaining city on Mars.
"I want to emphasise that this is a very hard and unsafe, difficult thing, not for the faint of heart".
