Told You So, Part 2


Elon Musk is serious about going to Mars:

Musk’s $500,000 ticket price for a Mars trip was derived from what he thinks is affordable.

“The ticket price needs to be low enough that most people in advanced countries, in their mid-forties or something like that, could put together enough money to make the trip,” he said, comparing the purchase to buying a house in California. [Photos: The First Space Tourists]

He also estimated that of the eight billion humans that will be living on Earth by the time the colony is possible, perhaps one in 100,000 would be prepared to go. That equates to potentially 80,000 migrants.

Musk figures the colony program — which he wants to be a collaboration between government and private enterprise — would end up costing about $36 billion. He arrived at that number by estimating that a colony that costs 0.25 percent or 0.5 percent of a nation’s gross domestic product (GDP) would be considered acceptable.

The United States’ GDP in 2010 was $14.5 trillion; 0.25 percent of $14.5 trillion is $36 billion. If all 80,000 colonists paid $500,000 per seat for their Mars trip, $40 billion would be raised.

“Some money has to be spent on establishing a base on Mars. It’s about getting the basic fundamentals in place,” Musk said. “That was true of the English colonies [in the Americas]; it took a significant expense to get things started. But once there are regular Mars flights, you can get the cost down to half a million dollars for someone to move to Mars. Then I think there are enough people who would buy that to have it be a reasonable business case.”

Here’s a link to his full interview with the Royal Aeronautical Society (H/T Clark Lindsey’s NewSpace Watch). This bit is also interesting:

Musk also ruled out SpaceX’s Dragon capsule, which the company is developing to ferry astronauts to and from low-Earth orbit, as the spacecraft that would land colonists on the Red Planet. When asked by SPACE.com what vehicle would be used, he said, “I think you just land the entire thing.”

Asked if the “entire thing” is the huge new reusable rocket — which is rumored to bear the acronymic name MCT, short for Mass Cargo Transport or Mars Colony Transport — Musk said, “Maybe.”

Not sure why you’d want to land the whole thing on Mars, unless the booster can be used again for departure. That’s a bit of a departure from their earlier concepts, in which Dragon was designed as a true multi-purpose vehicle, up to and including Earth re-entry at Mars return velocities.

And did anyone else notice the MCT speculation? Hmm…
