Velcroman1 writes: A manned mission to Mars would be the greatest adventure in the history of the human race. And one man knows how to make it a reality. In fact, he just wrote the book on it — literally. Joel Levine, senior research scientist with NASA's Langley Research Center and co-chair of NASA's Human Exploration of Mars Science Analysis Group, just published "The Human Mission to Mars: Colonizing the Red Planet." The book reads like a who's who of Mars mission science, featuring senators, astronauts, astrophysicists, geologists and more on getting to Mars, studying its atmosphere and climate, the psychological and medical effects on the crew and other details. There's even a section detailing the science of sex on Mars, should NASA attempt to create a permanent colony there. The most interesting bit: Levine presents a solution for funding the trip, something unprecedented for NASA: advertising. "The suggestion is marketing to different corporations and professional sports leagues for advertising, which is something NASA never does — it's a whole new economic plan for financing what has to be the greatest adventure in the history of the human race."
