Ticket to Mars

Elon Musk said that everyone can buy a ticket to Mars - it will cost only $100,000. The main goal is to make travel to Mars reasonably affordable. To build a city on Mars, you need to attract about 1 million people. The businessman wants to show the red planet to anyone who wants it. He claims that anyone can work or take out a loan to accumulate a notional amount of $100,000.
