Elon Musk, founder of Space-X, discusses his plans for colonizing Mars. From the Daily Mail:
Musk, already the first private space entrepreneur to launch a successful mission to the International Space Station this spring, says what would begin by first sending less than 10 people could blossom 'into something really big.'
. . . Rather than lounging around on an interplanetary vacation, the passengers would be sent to work, carrying with them equipment to build sustainable housing on the dusty and currently barren soil for future generations.
Immediate ground work would focus on building transparent domes pressurized with CO2 while possibly covered in a layer of water to serve as protection from the sun.
. . . With the CO2, Mars' soil would be capable of growing crops for food, he said.
Additional equipment carried over could also produce fertilizer, methane and oxygen using the atmosphere’s natural elements of nitrogen, carbon dioxide and its surface of ice water.
Musk believes one person out of every 100,000 people would be interested in making the journey with 8 billion expected on Earth by time his plans become reality.
Still, the first step is getting man to the Red Planet, a mission he expects to be completed in the next 15 to 20 years.
Once that's established, phase two would require a SpaceX design of a 'rapid and reusable' vertical-landing rocket, calling this: 'the pivotal step to achieving a colony on Mars.'
