Elon Musk Lays Out Vision for Expanded Mars Settlement (YouTube)

SpaceX Founder and CEO Elon Musk was the guest of honor at the United Kingdom's Royal Aeronautical Society on November 16, 2012 and presented a lecture entitled "SpaceX and the Future of Space Exploration."   During the talk, Mr. Musk said, "Some money has to be spent on establishing a base on Mars.  It’s about getting the basic fundamentals in place.  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." To watch the entire Musk address, please click here. [Image: SpaceX]
