lon Musk, CEO of SpaceX, delivered an address at the International Astronautical Congress held in Guadalajara, Mexico last year outlining his vision of getting humans into space. This talk has now been adapted into a fifteen-page article that was published in this month’s issue of the journal New Space. Musk focuses on affordability as a major factor to ensuring the possibility of Mars colonization. He says “You cannot create a self-sustaining civilization if the ticket price is $10 billion per person.” He believes that the cost should be about $200,000; equivalent to the median price of a house in the United States.
Musk outlines the steps he considers essential to ensuring this relative affordability. The first step, developing fully reusable transport, is already well underway at SpaceX. The company has already proven the reliability of its reusable rockets, and have recently demonstrated the reusability of the Dragon spacecraft. Fueling is also a key factor in controlling costs: equipping any craft with additional fuel will significantly increase the weight of the craft. Musk proposes using methane — which is produced on Mars and would therefore allow for refueling via sources directly on the plant.
