Your premise is that manned spaceflight is risky and expensive, and you gave NASA programs as "proof". I'm affraid nobody has ever tried it without learning that it's expensive and risky. The Russians, ESA, Chinese - none of them can come up and say "hey, it's cool - moderate to zero risk, and it doesn't cost that much after all!" So, it seems it's not only NASA. Most probably, the space travel is not intrinsically risky and expensive. With the current state of the art in technology, however, it looks like it is. Scaled Composites "repeated" a good portion of the X-15's ability to reach space with much less expense and no obviously major risk. Building up, to a great extent, on the knowledge, experience, and technology provided by the tax-financed pioneers. Besides, IIRC, the SS1 flight did experience a series of unexpected and uncontrollable rolls toward the end. The pilot (Melvill?) decided to ignore the "abort" command from the control and pushed on. He managed to accomplish his mission. Hadn't he been so lucky, however, the SS1 would now not be a glaring example of how far private iniciative can bring us, but rather a big smoking hole in the ground. I'm very happy it ended as it did, but let us not pretend it did not involve any significant risks. Maybe by some entrepreneurial magic he'll even be able to make it turn a profit. Not. Virgin Galactic apparently has a good business plan -- as long as the regulatory environment doesn't actively trip things up. They still need a vehicle to implement that plan, don't they? The scaled page is being quite silent about the progress of the SS2/WK2, almost one year after the historic SS1 flight. I hope this is just because they're too busy to update their pages. Cheers, alex. |

Building up, to a great extent, on the knowledge, experience, and technology provided by the tax-financed pioneers. That's not relevant. Both government and private spaceflight have the pioneers' work to build on, so you can't use it to denigrate the lower costs demonstrated by Scaled. But did taxes finance the development of SS1's hybrid rocket motor? Its "feathering" descent stabilization scheme? Its composite construction techniques? Its avionics? Besides, IIRC, the SS1 flight did experience a series of unexpected and uncontrollable rolls toward the end. That was the very first flight out of useful atmosphere; unexpected events were, um, expected. They did figure out the cause of the roll *and* the way to mitigate it for the actual X-prize-winning flights. The pilot (Melvill?) decided to ignore the "abort" command from the control and pushed on. He managed to accomplish his mission. Hadn't he been so lucky, however, the SS1 would now not be a glaring example of how far private iniciative can bring us, but rather a big smoking hole in the ground. If the pilot had lost consciousness, perhaps that might have happened. But SS1 was designed to have good aerodynamic stability, and with a pilot at the controls it would almost certainly still have landed fine even if the first-flight roll had ended up making it miss its altitude target. |

Are you going to put your tourists to work or treat them like it is Las Vegas? I suspect that you really wonder why astronauts even bother to collect their pay, don't you? No, Eric. I just wonder why you take such joy in broadcasting your cluelessness and inability to follow a subject on a daily basis. It's an eternal mystery. The eternal mystery to me is that year in, year out, Rand Simberg continues to protest too much about engaging with people he claims to think are idiots/fools/logically impared and one of a dozen other "Randianisms". So much so that he contributes almost a quarter of the traffic of the newsgroup. What particularly astounds me is that he'll respond to questions with flame bait designed to perpetrate even more postings. Why Rand? Why? Dave |

There's still hope that airplane might come along and provide for
practical means of air transportation. -kert |
