the moon is our backup drive
Monday, April 12, 2010 at 09:32AM My two year old son loves the Moon. He sings about it all day long. He can't wait for nightfall when I lift him into my arms to hold him ever closer to its magical glow. But my son isn't alone in his adoration of the Moon. Imaginative new ideas for using space to protect civilization against existential risks, such as killer asteroids, nuclear war, and global terrorism, are in the works by scientists and futurists from all parts of our world.
You can think of the idea as backing up civilization's collective hard drive—its recorded archive—on the Moon and creating a self-sufficient colony there precisely so it can act as a lifeboat in case a calamity strikes Earth. in my estimation, the overarching reason for moving to the Moon should be safe harbor, not to mine resources, or for the sake of a grand adventure. And the move outward must start with the Moon, not Mars. The Moon is three or four days away, not a year, so it makes logistical sense and is cheaper. And if there's an accident on the Moon, help or a safe haven are likewise four days away. Finally, the lunar colony ought to be NASA's overriding (but not only) mission, especially since it walked off a cliff after Apollo.
In his recent book "The Survival Imperative: Using Space to Protect Earth," author William E. Burrows presents a dramatic scenario of a killer-asteroid impact and highlights other existential risks facing the Earth, including nuclear war, terrorism, and in the future, gray goo and nanoweapons—"a far greater danger" than nuclear weapons, he says, quoting Ray Kurzweil's "The Age of Spiritual Machines." And he lays out a revitalized national space program that coordinates efforts in global defense, environmental protection, communications, and military security. "Planetary defense should be conducted, not as a major program within the space agency, but as the agency's highly focused, overarching, mission.... The core mission, in its totality, would send humans and robots to space for mutually supportive operations specifically designed to protect the planet. That is to say, NASA, its collective foreign counterparts, and other cooperating U.S. agencies, should assume the role of Earth's guardians."
