NASA is retiring the whole Space Shuttle program, and replacing it with who knows what (you might; I haven't really been paying attention). They're repurposing what equipment they can repurpose, and the stuff they can't they're selling, including the shuttles themselves. Two are still available, Atlantis and Endeavour, going for 28 million dollars each. If you don't have money for a whole shuttle, why not just get a shuttle engine; they're entirely free. Plus shipping and handling. In unrelated news, for sale: one jumbo jet, lightly used, good as new, minor barely noticable water damage to upholstery.
