The KSC Townhall meeting with Mike Griffin, who referred to an MSNBC article calling him "King Nerd", is online at:<br /><br />http://www.nasa.gov/audience/formedia/speeches/index.html<br />http://www.nasa.gov/pdf/116056main_Mike_Griffin_Town_Meeting.pdf<br /><br />I thought the following text in the transcripts illustrate the difference between Griffin and O'Keefe:<br /><br /><blockquote><font class="small">In reply to:</font><hr /><p>The use of the L-points carries a delta v penalty in the variously several hundred meter per second range to use it effectively and it carries a transit time delay of a couple days on either side, so you have to carry consumables and stuff to make up for that and people are sitting around twiddling their thumbs and so whether or not the L-points are useful in our first stages of lunar return I kind of doubt. In the context of a more fully developed architecture, if you fast forward 20 years in the future and we’ve got a base on the moon and it’s like McMerto in Antarctica, then I can see a role for the L-points in that kind of scenario if, again, and mostly L-1 if that makes sense. But you probably didn’t actually invite me here to discuss orbital mechanics. I mean, I can, but then I need a whiteboard or something. <p><hr /></p></p></blockquote><br /><br />I can't see O'Keefe responding like that <img src="/images/icons/smile.gif" />
