Rifleman - 5/3/2008 9:38 AMQuoteANTIcarrot - 5/3/2008 9:25 AM for some missions the removal of the first-stage recovery system for a "significant capability increase".I may be wrong about this, but I thought that the capability to cast new SRB segments no longer exists. Is it really a good idea to turn a limited and non-renewable resource into an expendable item?

OV-106 - 5/3/2008 9:22 AMHow many of you have rocket scientist degrees on your wall?
OV-106 - 5/3/2008 10:22 AMFolks,I was there at that conference. Honestly, how many of you are truely qualified to judge? How many of you have rocket scientist degrees on your wall? Are there problems? Yes. Are there engineering issues to be resolved? Sure.

Or send me their FEA model and I'll run my own acoustic and vibration studies! That I AM qualified to do.There are major problems on both sides. I just vehemently disagree with Griffin's off-hand dismisal of a concept like DIRECT. The Future of NASA's manned space program depends on him getting it RIGHT.. not just making the first part marginally work and making the second part(Ares-V) so incredibly expensive that it will never get funded by a new administration. I don't think many here question NASA's technical ability to make Ares work in some fashion or another. The question is.. Is it really the right(cheapest, fastests, with most re-use) path.. and will we ever get to the Moon or Mars if they follow this path?Everyone here wants the most effective and affordable vehicle to get us to the Moon, Mars or a NEO. Agreed?

OV-106 - 5/3/2008 9:37 AMMy point is this thread will fill up with people dropping by to say the same old thing they always say, drop back out and wait for the next thread to do it all over again.

Yes. Are there engineering issues to be resolved? Sure. I'm all for vigorous debate which this site used to really inspire but lately it's come down to just a bunch of trash talking and draging names through the mud. If you're a casual observer with an interest in this stuff, great. I applaud that and welcome your participation. However, if you just "troll" because of other posts or things you have read from others who hide behind a screen name then I ask you to take a step back and examine your objectivity.Another thing, I'm really tired of seeing thread after thread of how "this person is doing this wrong and those people are to blame for this or that. If they would just listen to this or that everything would be fine", etc. The funny thing is nothing in these threads is new. Just the same old folks throughing their little one liners out there.

OV-106 - 5/3/2008 11:12 AMWhy should anyone send you the data for you to run your own model? I'm glad you are qualifed but does that mean you are entitled to it? Why do you assume that direct is so much better for a launch system still in design concept, could it be because you are biased? Sure everyone wants something that is the cheapest, etc. Unfortunately, many assume that there is some evil force at work that is out to screw everything and will trash everyones name conncected to it without making a clear point. Not the best and most strategic tact if you want to sell something.

I'll see your degrees on the wall and raise you actually working on one of the vehicle in question. If you're workload was to continuously find ways to strip mass off Orion due to Ares' problems, you might be able to speak more on knowing a bit more than listening to Cook's happy talk at a conference.
