Thousands of billionaire Tesla, Elon Musk, said it will not fall to Mars, despite the high personal risk.
Space X chief executive said 70 percent change was going to go to the red planet, but Ernest Shackleton travels a similar trip to the Antarctic journey.
"We've done a lot of progress we've done recently," said Musk.
But he dismissed claims, that is, he was only one million retirees.
"The death of Mars is far greater than the Earth's probability. In truth, the announcement to go to Mars to Shackleton would be an announcement to go to Antarctica," he said.
"It will be tough. There is a good chance of death, while it's a bit of a deep space."
"If you succeed enough, you will continue to work on the foundation," added Musk.
"So, you know, there's not a lot of entertainment time. After all this, the environment is very hard. […] There's a good chance to die there. "
"We think that you can return, but we are not sure. Now, is it like the escape window of the rich people?"
