Elon Musk just revealed his plans to colonize Mars and make it fit for human habitation.

Elon Musk publishes 15-page manifesto to colonize the Red Planet and made available for free.

Musk predicts in

“We are going to try to send something to Mars on every Mars rendezvous from this point on. We plan to send Dragon 2, which is a propulsive lander, to Mars in a couple of years, and then probably do another Dragon mission in 2020.

Therefore, you could travel out to the Kuiper Belt, to the Oort cloud. I would not recommend this for interstellar journeys, but this basic system –provided we have filling stations along the way – means full access to the entire greater solar system.”
