Space Forum / Shuttle / July 2005FIX THE FOAM
I guess I should not be surprised that NASA still has not fixed the FOAM problem. I thought at least they would go back to using Freon see http://www.newsmax.com/archives/ic/2005/7/28/93055.shtml Its the soam ole problem from years ago and it appears they have yet to take is seriously.

The foam which has separated from the shuttle in the past was from areas which used the old process. The CFC foam was only applied to the broader areas of the tank and has not been the problem. Newsmax is a right wing loony tune website who will use any excuse to blame "liberalism" for everything wrong in the world. > The crap about the Clinto CFC free foam is a newsmax lie.

I don't know if they lied or not. But its been my experience that the extreme liberal sites tend to lie more. I wish there was an honest news source but not sure which one is. David A.

I thought [quoted text clipped - 8 lines] > >David A. Scott Newsmax needs to brush up on reality The foam that caused the Columbia disaster was shed from the bipod ramp area. That and the PALramp foam seen departing from Discovery is applied by hand and still uses the ecologically unfriendly CFCs during the application process. The change in 1997 was only made to the "acreage" foam which is applied mechanically, hence the foam they put into question was not a factor. > I guess I should not be surprised that NASA > still has not fixed the FOAM problem.

I thought >> at least they would go back to using Freon > >Why go back to a foam that HAD THE EXACT SAME PROBLEM!!!!! According to a report, the previous foam was worse. The number of hits from foam shredding from the tank was highest in the 1980s and in 1997, where they were in transition and still used a tank which was coated using the old process. Besides, the new foam apparently isn't where the shredding problem is from, it's from an area which the old process is still used and applied manually. > I guess I should not be surprised that NASA > still has not fixed the FOAM problem.

Figures. One of the first requirements for a carreer in science or engineering is the ability to observe things objectively. You continue to demonstrate an inability to do that. No wonder you're bitter. > Oh God, not you again. And you're a newsmax junkie now too?

No wonder you're bitter. Actually I was quite successfil as an engineer. What did you do with your life. One of the requirements to have been a successful engineer who even worked at NASA is the ability to put up with people like you. Yes I worked for NASA big deal. I think I may be a lttle bitter that NASA may have not yet learned from its mistakes not sure the engineers yet there have the ability to speak out. I would not call myself a NEWSMAX junkie it just came up on a Google search. I do hope NASA can fix the foam problem it should have been done during the years they had. I feel NASA was a much better and productive place back in the earlier years not sure they can capture that again. But I do hope that maybe that spirt will some how come alive again with something like a goal of maned filght to Mars and with possibly using real engineers as managers again that have worked there way up through the ranks there is a possiblity of hope. The one thing I learned from years of work for the government the fastest way to destroy a project is to have snobish mathematically and science challenged managers calling the shots. There should be some sort of mathematical and physics I.Q. test that if they are not in the top 10% they should have no business telling an engineer what to do. I have not written much because since the crash there is only so much one can say. Also when one gets old ones health starts to decline. I doubt I will be alive to see mankind make it to Mars but I hope it does before we destroy ourselves. Bush has failed us but I don't see a John Kennedy in either party both seem to have lost the faith and the way. David A.

Scott just thought I would add this post to NEW YORK TIMES I suspect those that hate NEWSMAX may kiss the feet of the liberal times http://www.nytimes.com/2005/07/31/science/space/31foam.html?ei=5065&en=9328 0ea1193e7512&ex=1123387200&partner=MYWAY&pagewanted=print Its about the foam problem to quote the times "After two and a half years, they should have been able to fix the foam," said Paul A. Czysz, a professor emeritus of aeronautical engineering at St. Louis University and a veteran consultant to NASA. Of course I suspect Bruce may be ready to bad mouth him too. David A.

Did they even consider using a different foam formulation ? They though they fixed the "Popcorning" problem by punching little holes in the foam to let the air escape. But if they had modified the foam's formulation to be more maleable/soft, then bubble expansion would have just made the foam "inflate" a bit, instead of causing cracks leading to foam bit falling off. Seems to me that they spent 2 years trying to justify the continued use of that foam instead of looking at something new. Yeah, the standard NASA-apologist excuse will be "but any new material would have required years and years of testing". Yet, these same apologists are quick to say that CEV will be ready within a few years, despite the fact that it isn't even something that exists on paper yet, NASA promised the CAIB that he had fixed the foam problem before it was granted the right to fly. In the end, it seems that they did a lot of work to justify not changing much. Hopefully there weer dissenting voices within NASA who had ideas about real fixes for the foam problem, and now that the know-it-alls have proven their solution failed, the other guys will be given a chance. >> Its about the foam problem to quote the times >> [quoted text clipped - 28 lines] > real fixes for the foam problem, and now that the know-it-alls have > proven their solution failed, the other guys will be given a chance. My feeling is the dissenting voices may have already been scilenced. I suspect that the desire for management protection overides everything else and it would be embarassing at this point to show that some of those in the know had real concerns. I still don't see why a cocoon or something that just slips off at takeoff couldn't be used. It would add nothing to the payload and the cooling is not needed for the short use of the booster. I am sure there are many other ideas. Maybe they will actually look at some this time. David A.

I get a kick out of Newsmax's lying by omission. Nothing like Left Wing Foam. :) |
