<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>This is why I prefer prizes and competitions compared to the old way of doing things. NASA is simply buying a service just like when someone buys a seat on an airplane - since most jet airliners move at about the same speed it doesn't matter what jet the airline puts you on as so long as it gets you to your destination. Without the need for a literal act of Congress to make a change to the system, companies like SpaceX can be more responsive to new data. <br /> Posted by PistolPete</DIV></p><p>It is also far more risky, and NASA absolutely has an adverse relationship with risk. As witness that it took some 4 different launches of the Falcon I before spacex got it correct. Also, and even more, witness the more experienced (but far less experienced that either Boeing or LM, or even the combination in ULA) Orbital Sciences and their latest problem.</p><p>On the other hand to my knowledge there has been absolutely no failures of the Delta II used by NASA for launch after launch of its Mars and other probes. The last failure of such a launch (and that was non NASA) occurred before I retired in the year 2000. The Delta II system is either the most reliable or nearly the most reliable such launch system in the world. There have been no failures of the system in the last 75 launches!!</p><p>And that is why NASA uses the Delta II for such greatly important launches as almost every Mars vehicle launch that NASA has made. After all, it is difficult enough to get a working space craft to Mars without the launch system failing to even get the system into orbit in the first place!</p><p>I had actually worked in manufacturing Quality Assurance for Rocketdyne for most of my 37.5 years of working career, and I can tell you now that reliability of such systems as rocket engines IS far more important than ANY cost!! It makes no difference at all just how inexpensive such a system is, if it even fails even as little as 10% of the time!</p><p>And while I wish them all the luck in the world, NONE of the newer alt.space outfits comes even close to the kind of reliability that backs up such as ULA, NONE!</p><p>Even Elon Musk himself has had to admit that getting a working launch system off to a reliable start is far more difficult than he originally thought it was going to be. Such an admission does bode well for his efforts however, for realizing just what you are up against is the first step in overcoming what you are up against!</p><p>Unlike some of the people here, I am not against the newer alt.space companies. but unlike even more people here, neither am I against the more experienced companies either! Having been one of the some 400,000 workers that put men on the moon I can be idealistic and fully support ALL such launch efforts. I believe that I state an absolute truth when I say that for spacex to establish the kind of reliability records of the more experienced launch companies (including the Russians) spacex is going to have to have quite a few successful launches of their much larger Falcon 9 system. And this is going to have to be done while at the same time keeping far lower costs, a very large challenge!</p><p>Even if some people here do not seem to want to realize this! </p><p>And we have not even left earth orbit since Apollo, not because of NASA or ANY of its contractors, but because of the incredible stupidity of a government that would rather fight wars and blow holes in rice paddies in South Eastern Asia, or blow holes in the deserts of the Middle East, than develop a true space faring civilization! </p><p>If Von Braun had continued to get the kind of support that the greatest space program in history should have had, we would have colonies on both the moon AND Mars by now! It is NOT the fault of either NASA nor its contractors that we are now in the situation in space development that we are now in, but in the absolutely stupid human waste of war!! </p><p>And until that kind of stupidity changes mankind is eventually (and sooner than many are aware of) doomed!!</p><p>IF that particular problem was over come and NASA given even a budget of only half (1% average) of what we had back in the 1960's (2%), then there would be far more work for all companies, experienced and alt.space together, and we (the US) could then lead the entire world into a true space faring civilization before humanity totally uses up this spaceship Earth!</p><p>And THAT is THE real problem.............. </p><p>I really do not know just how to solve that, does anybody?</p><p>Oh, by the way, launch costs of even the ELV and EELV systems are already far less than 10% of an actual spacecraft, whether a commercial satellite, or a human launch to the ISS! And with so much competition for so few new launches, once again, reliability is absolute king over cost! </p><p>However, I still wish spacex all the success in the world, in particular as I live in Southern California myself, and their success (along with such as t-space and sealed composites) is vital to a long overdue revival in aerospace in this area! </p><p> </p><p> </p>
