Elon 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 months 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 itsreusable rockets,and have recently demonstratedthe reusability of theDragon 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 thereforeallow for refueling viasources directly on the plant.

Many experts believe that in order to ensure the survival of our species, we must work to be multi-planetary beings. Perhaps Musks vision to get us to Mars is the first step toward that goal. Musks enthusiasm for his Mars project is quite timely if we are to believe Stephen Hawking, who predictshumanity only has 100 years left on Earth.

But colonizing Mars is only a one possibility space has to offer. Space miningand manufacturingcan help to decrease the burden on Earths resources and give us the capabilityto create products that would be impossible to manufacture on Earth.

We are at the beginning of an exciting crossroads for humanity. The space race of the mid-20th century brought about great change for humanity. Its looking like this iteration will completely transform us.
