Gregg Easterbrook. "Moon Baseless". Slate. Dec. 8, 2006: "Don't we need a moon base to go to Mars? No! When George W. Bush made his Mars-trip speech almost three years ago, he said a moon base should be built to support such a mission. This is gibberish. All concept studies of Mars flight involve an expedition departing from low-Earth orbit and traveling directly to the red planet. Stopping at the moon would require fuel to descend to the lunar surface, then blast off again, which would make any Mars mission hugely more expensive. The launch cost of fuel—that is, the cost of placing fuel into orbit—is the No. 1 expense for any manned flight beyond Earth. The Lunar Excursion Module, the part of the Apollo spacecraft that touched down, was two-thirds fuel—all exhausted landing and taking off again from the moon. Rocket technology hasn't changed substantially since the 1960s, so a large portion of the weight of any Earth-to-Moon-to-Mars expedition would be dedicated to the fuel needed for just the layover. This makes absolutely no sense, and the fact that administration officials get away with telling gullible journalists that a Mars mission would use a moon base shows how science illiteracy dominates the big media. (It is imaginable that a moon facility could support Mars exploration by refining supplies from the lunar surface and then using automated vessels to send the supplies to the red planet, or to rendezvous with an expedition en route. But that's pretty speculative, and at any rate, the cost of building a moon base would far exceed that of simply launching the supplies from Earth.)"
