Open letter from Homer Hickam to NASA astronauts

Homer Hickam, whose book and early life story was made into the movie "October Sky", has written an open letter to NASA astronauts urging them to go on strike or to otherwise make a stand to protest the Obama space policy that is strangling the life out of manned spaceflight. It's a good letter. Hickam makes the connection that Obama science adviser John Holdren, who is a huge Luddite, is probably behind the policy.
