Add critical reading skills to the list of apparent deficiencies of space enthusiasts.<br /><br />Rocket man himself has stated on this very blog that there are critical spares for SSME 'engine flights' of upwards of thirty remaining flights. If the A-team does anything, it will be to preserve these critical assets from the scrap yard or the trash bin.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3673435362400368888.post-49358721633087400702009-06-26T10:24:20.512-07:002009-06-26T10:24:20.512-07:00Dozen's??

I'm sure the incompetents of NASA can screw up a second generation engine development program during the time and money that dozens of cargo carrying developmental rocket flights to low earth orbit (the ISS) can buy them.<br /><br />The lack of critical thinking skills among the American public, the representatives they elect, and the administrators and engineers they employ is nothing less than <b>ASTONISHING</b>.

NASA did not buy SSME's and shut down the production line, they kept the manufacturing facilities and personnel available at Canoga Park and West Palm Beach while also paying for the "reuse" assets at KSC. The manufacturing line is required for spare parts and design mods. This infrequent buying of parts is prohibitively expensive. For SSME's it is much more cost effective to build a simpler expendable version and then concentrate on optimizing the costs of a steady production process through well known industrial technology methods. The thought that we save money through reusing main engines is what is wrong.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3673435362400368888.post-29074650761707079322009-06-21T21:15:17.116-07:002009-06-21T21:15:17.116-07:00The attack also appears to have been closely coord...<i>The attack also appears to have been closely coordinated with Cooke and company.</i><br /><br />Indeed, they come from a long line of incompetent managers and engineers.<br /><br />"Reusability is a myth".<br /><br />Classic incompetence.<br /><br />Made my day.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3673435362400368888.post-35685399363213045502009-06-21T14:50:05.474-07:002009-06-21T14:50:05.474-07:00Cooke may have been sweating, but I think he gave ...Cooke may have been sweating, but I think he gave a masterful performance. He was calm and professional and he even managed to make his presentation boring and to portray his project as coming along smoothly. That's quite a feat for a project that going down in flames.<br /><br />And I don't think he had anything to fear from Shannon. Shannon’s presentation on Not-Shuttle-C appeared to me to be a very subtle, calculated and brilliantly executed attack on DIRECT, without even mentioning it by name. He undermined the credibility of DIRECT’s claims J-130 can help close the gap by showing Not-Shuttle-C is more direct than DIRECT itself and still cannot close the gap. He also suggested that anything less than Ares V (in particular Not-Shuttle-C, but including Jupiter by extension) would lead to a less capable lunar architecture. This invites the conclusion that if you are willing to wait longer for an inline SDLV you might as well go for Ares V.<br /><br />The attack also appears to have been closely coordinated with Cooke and company. Take a look at the only backup slide in his presentation: it’s a chart that suggests Not-Shuttle-C is much simpler than both Ares and DIRECT, whereas DIRECT is about as complex as Ares. This is very misleading, DIRECT is more like halfway between Not-Shuttle-C and Ares. I cannot help but think this was done deliberately. The claim that Not-Shuttle-C would require a smaller lander is false by the way.<br /><br />And with DIRECT shooting themselves in the foot with their office logistics (they sent in a confrontational earlier draft of their presentation instead of the more polished and professional later version that removed some of the harsh language) and the Q&A session (there were snorts of derision from the panel), Cooke and Shannon can look back on a very good day on the DIRECT vs Ares front.<br /><br />All highly regrettable, but that's how I see it.Martijn Meijeringnoreply@blogger.comtag:blogger.com,1999:blog-3673435362400368888.post-33332960693911186802009-06-20T11:35:18.242-07:002009-06-20T11:35:18.242-07:00And the audience has received it's behavior wa...And the audience has received it's behavior warning from management. Essentially, the Augustine meeting is mandatory; you will at least pretend to pay attention; when the cue cards are held up do what it says - Oooo, Ahhh, clap vigorously and perhaps an 'amen' might be a nice touch. Oh, if asked any questions, give the party line or call your manager over to approve your comment. Otherwise, keep your hands in your pockets and your mouths shut. Do not make eye contact, remember you are not important in this equation - minions never are.<br /><br />If that wasn't enough, the leaders of the Lazy B let it be known that about half of the local minions will be gone before the new fiscal year arrives. Wonder what their selection criteria will be?<br /><br />You can bet your hat and your house cat that the Augustine commission is going to get a real earfull when the notices are given to those who chose to tell the truth and stand up for what is right, wind up getting layoff notices!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3673435362400368888.post-68302036475390503682009-06-20T10:30:59.153-07:002009-06-20T10:30:59.153-07:00Direct 3.0
