> <i><font color="yellow">it's okay for you to not like the shuttles... I have made a few anti-shuttle posts myself, as I believe they represent stagnation.</font>/i><br /><br />I also have a history of criticizing the shuttle (and ISS), but cutting and running is very difficult.<br /><br />First, as has been mentioned here many times, for technical reasons the shuttle is the <i>only</i> vehicle that can launch most of the rest of the equipment for the ISS. Because so many other countries have invested money in equipment for ISS, the US is pretty much stuck with having to continue building out the ISS. And this means keeping the shuttle flying.<br /><br />Second, as I am starting to discover, NASA is to a great extent a government funded jobs program. This was drilled home for me when during a Q&A for the Moon2Mars report Aldridge said if they had proposed closing a NASA facility their report would have been dead on arrival. I have also read several times where Congresspeople have gone on the record saying there will be no closing of NASA facilities (at least in their district or state). Killing the shuttle program will kill a lot of jobs, and that will cost votes.<br /><br />Third, while I hope the replacement vehicle will be safer, we will have no guarantees until it has flown 50-100 flights. We often brag about how successful the Apollo program was with respect to launches, but the total number of flights were just a fraction of what the shuttle has flown. Perhaps by the time we had gotten to flight Apollo 63 we might have had some fatalities too.</i>
