Musk said that colonizing Mars won't be for the faint of heart.

In a video interview with Chris Anderson, Musk said that Mars will not be luxurious in the beginning.

The billionaire compared recruitment efforts for Mars to an ad from the 1900s for an expedition to Antarctica. The ad was a myth, but called for men to go on a hazardous journey, and said a safe return was questionable.

The sales pitch for going to Mars is cramped and dangerous. You might not make it back. It is hard work, Musk said.

Living on Mars, a planet with an average temperature of -62.22 degrees Centigrade (-80 degrees F), would be far more difficult than living in a region with an average temperature.

There are volcanoes and canyons on Mars. Insider previously reported that a human without special equipment would die on the planet due to its low atmospheric pressure.

Musk wants to build a city on Mars. It would take one million tons of cargo to build a self-sustaining city on the planet.

Anderson was told by the billionaire that he hopes the people that colonize Mars will rethink society.

I think this is important for maximizing the probable life span for humanity or consciousness, Musk told Anderson.

Human civilization could come to an end for a number of reasons, including a giant meteor or super volcanoes, extreme climate change, or World War III.

The richest man in the world told Anderson that the price of future rockets to Mars would be relatively affordable for most people.

In the coming decades, Musk's company plans to build a self-sustaining city. Anderson was told by the billionaire that he will be dead before his dream can become reality.

In 2020, Musk said he would send 1 million people to Mars by the year 2050. He said that the first human on Mars might land in 2029.

The CEO of the space company told Anderson that they could have their first launch within a few months.

Success is not guaranteed, but excitement is.
