Elon Musk: Moving to Mars would cost about $200,000
The CEO once said a self-sustaining Mars colony won't work if it's wildly expensive for each person to make the voyage.
- Musk has said that he wants to keep the per-ticket cost of traveling to Mars roughly equivalent to the cost of a house in the U.S.
- SpaceX plans to send a cargo mission to Mars in 2022, followed by a manned mission in 2024.
- Musk said there's a 70% chance he'll travel to Mars. A recent survey suggests most Americans aren't quite as adventurous.
A ticket to the red planet aboard a SpaceX rocket will likely cost "a couple hundred thousand dollars," according to CEO Elon Musk.
That may be expensive, but it's a price point that would make the voyage feasible for people who aren't incredibly wealthy.
"If we can get the cost of moving to Mars to be roughly equivalent to a median house price in the United States, which is around $200,000, then I think the probability of establishing a self-sustaining civilization is very high," Musk said last year.
The billionaire entrepreneur provided something of an update Sunday to Axios during its final episode of its limited documentary series on HBO, reaffirming that the company was aiming for that price point and denying that the voyage would be an "escape hatch" for the rich.
"Your probability of dying on Mars is much higher than Earth," Musk said, comparing a hypothetical ad for the Mars voyage with Ernest Shackleton's ad for going to the Antarctic, which read: "Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honor and recognition in event of success."
He added that it's unclear whether Mars inhabitants would be able to return to Earth. As of November 2018, SpaceX has an "aspirational goal" of sending a cargo mission to Mars in 2022, followed by a second manned mission in 2024.
Musk says he might go to Mars "for the challenge"
Musk told Axios there's a "70 percent" he'll make the voyage to the red planet. When asked why he'd in light of the dangers, Musk said, "There's lots of people that climb mountains. You know, why do they climb mountains? Because people die on Mount Everest all the time. They like doing it for the challenge."
Most Americans aren't quite as adventurous. When asked how likely they'd be willing to travel into space if it were free, 35% of Americans said "extremely likely" while 31% said "not at all", according to an Axios survey conducted in November.

Philosophers like to present their works as if everything before it was wrong. Sometimes, they even say they have ended the need for more philosophy. So, what happens when somebody realizes they were mistaken?
Sometimes philosophers are wrong and admitting that you could be wrong is a big part of being a real philosopher. While most philosophers make minor adjustments to their arguments to correct for mistakes, others make large shifts in their thinking. Here, we have four philosophers who went back on what they said earlier in often radical ways.
Just before I turned 60, I discovered that sharing my story by drawing could be an effective way to both alleviate my symptoms and combat that stigma.
I've lived much of my life with anxiety and depression, including the negative feelings – shame and self-doubt – that seduced me into believing the stigma around mental illness: that people knew I wasn't good enough; that they would avoid me because I was different or unstable; and that I had to find a way to make them like me.
A joint study by two England universities explores the link between sex and cognitive function with some surprising differences in male and female outcomes in old age.
- A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
- The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
- The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.
