No, today we'll celebrate the beginnings of the space merchants. A non-government space shot worked. Now think about that for a moment. Speculative fiction prior to the mid- to late-1950s ascribes the beginnings of space travel to private industry, later dominated by quasi-Horatio Hornblower "space navies" of more than trivial governmental function. In fact, man didn't get into space by private enterprise alone; at least not until now. (If, that is, we pretend that military research and development had nothing to do with most of the materials from which SpaceShipOne was constructed.) The real questions that this flight raises have little to do with the technology; they are instead those same questions raised at Kitty Hawk in December 1903. The technology will improve.
They key is whether there is a disaster that sets us back as far as did Columbia and Challenger in our willingness to exploit space with nongovernmental lift capability. My the use of that little bit of government logistics-speak should indicate my pessimism for the next decade or so. After that, the crystal ball is hazy; ask again later.
