			<content:encoded><![CDATA[<p>By NASASpaceFlight.com. At their subscription site.</p>
<p>Jon Goff has <a target="_blank" href="http://selenianboondocks.com/2009/05/reason-to-get-an-nsf-l2-subscription-2921-esas-appendices/">a few interesting details from his first look at the appendices</a>:</p>
<blockquote><p>Now, having seen some of what’s in them (I’ve mostly been focusing on the 300+ page appendix to Chapter 6, that details all of their launch vehicle related decisions), I can understand why some people might not want that data to see the light of day. I was hoping to get permission to post a screenshot or two and some direct quotes, but for now you’ll have to get a subscription and check it out yourself.</p>
<p>Some gems to look for when you get a chance, all within the first 40 pages:</p>
<ul>
<li>Exceptions given in the ground rules and assumptions on maximum dynamic pressures to In-line SRM based crew launch concepts that weren’t given to any other vehicles (without the exception, all of the five-segment Stick concepts would’ve been ruled out from the start).</li>
<li>Unrealistically assuming a fixed LAS mass regardless of first stage characteristics (like T/W, max-Q, and whether you can shut them down or not).</li>
<li>Inaccurate dry mass numbers for existing EELV upper stages (just as some of the guys on NASASpaceflight.com had been saying for years now).</li>
</ul>
</blockquote>
<p>Hmm&#8230; It&#8217;s almost as if the study was rigged to generate a particular outcome&#8230;</p>
<p>I can&#8217;t wait to see what other &#8220;gems&#8221; are buried in the full text. Of course, I will wait, since I&#8217;m not going to pay for a &#8220;level 2&#8243; subscription at NSF to obtain copies of information that I&#8217;ve already paid for (that, and I&#8217;m not going to help support a site which I loathe for its constantly-flickering animated ads).</p>
