Details of Elon Musk Goal of getting 80,000 people per year to Mars

Elon Musk had a November 16,2012 talk at the Royal Aeronautical Society where he rolled out his plan for a major colonization of Mars. He followed up on twitter

Millions of people needed for Mars colony, so 80k+ would just be the number moving to Mars per year…

He actually planned to send 80,000 people to Mars every year once the colonization begins. He says he knows it sounds crazy to some and he also says that he does not expect Spacex to do it alone.

Reusable rockets are the difference between something costing half a percent of GDP and all of GDP.

At a joint press conference with NASA , SpaceX CEO Elon Musk said the company will try a water landing of its Falcon 9 first stage later year (2013). The landing will be the start of a series of flight tests that could culminate with an attempted propulsive landing of a first stage back at its launch site in the middle of 2014, Musk said. A successful propulsive landing would enable reusable rockets which could lower the cost of launching to space by 100 times.

Elon Said

The cost of the propellant is only about 0.3 percent of the cost of rocket. And we have a low cost rocket….The Falcon 9 is 60 million dollars, and that’s for something with four times the thrust of a 747 and about the same liftoff mass. So that’s a good deal. But the propellant is only 200,000 dollars. So if we could use the — hypothetically use — Falcon 9 rocket 1,000 times, then the capital cost would go from being 60 million dollars per flight to 60,000 dollars a flight.
