ZeroGeezus,<br /><br />When comparing the SpaceShip One suborbital flight with the Mercury suborbital flights, one must remember that the term"suborbital" can be used to to describe two very different flights.<br /><br />SpaceShip One goes straight up, and comes straight back down. There is very little down range velocity. This is to minimize the heating to the vehicle.<br /><br />If you take off from Florida and land off the coast of California 50 minutes later, that is also a suborbital flight, even though peak altitude was as high as an orbit, and peak velocity is several miles per second. I cannot remember, but it seems to me that both of the Mercury suborbital flights landed in the Indian Ocean, only about 15 minutes after launch. I think that testing the heat shield was part of the flight.<br /><br />Spaceship One is a cool vehicle, and the flights are awesome. But they are a very, very long way from approaching what the Mercury guys did on their suborbital flights. Of course, they were 'Spam in the can', with hardly any say in where they were going, other than when the re-entry burn started. SpaceShip One has to be piloted, from ignition to roll-out.<br /><br />I think that we will see a totally different configuration of vehicle when Rutan starts taking on that several-miles-per-second down range velocity. We may also see a completey different type of rocket, as well. It is easy to call NASA names, but building the hardware to do what they do is neither cheap nor easy. I am sure that Rutan can do it, along with the engineers who work with him, as long as Paul Allen is willing to spend a good chunk of his fortune.<br /><br />NASA was never given the objective to get people into space cheaply and with a minimum of hardware. They have always had much more difficult goals to fulfill. Had they been directed to come up with a simple, reliable, inexpensive launch system 20 years ago, they would have. But the name of the game these days is keeping the contractors a <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>
