When offshore, I like to stand on the foredeck touching the rigging but not using it for balance. Feel the wind, waves and motion of the boat. Become one with the boat so to speak, wonder if those were Musgrave's thoughts. |

Jorge R. Frank wrote: wrote in : Remember the question why NASA did not release their results on the in orbit repair options for Columbia? Incorrect. The results were released with the CAIB report, both as a chapter in the main report and as an appendix. The only "results" they released was a statement that their tests were inconclusive. No report what they tested, how they tested neither the results they got. They did no materials testing, only analysis, and very limited analysis at that. They didn't just say the analysis was inconclusive. They said more than that. "The assessment of the level of difficulty of the repair operation is high. The level of risk to the crew is moderate and the risk of doing additional damage to the Orbiter is high (i.e. enlarging the wing leading edge breach). The overall assessment of the expectation of task success is moderate to low, depending on damage site characteristics and the required repair technique." "The results while inconclusive, do not indicate this option was likely to succeed." It seems the results were too unwanted obvious: Gutierrez is wrong. And it turns out, so were NASA's results from the CAIB report. The three years of work that have gone into RCC repair capability since that report have made clear that the in-flight repair options for Columbia would not have worked. What is your source? Was it you who said something the same line over a year ago claiming some knowledge of NASA tests not yet released? As we got no source it was dismissed as one of the many Columbia Usenet myths. But maybe there is a report out now. I`m not the only one eager to read it! It depends on what you mean by "report". NASA has published no report directly addressing Columbia repair on STS-107. But then again, that's not necessary. What I did was to read the CAIB report, both Volume 1 section 6.4 and Appendix D.13, and make careful note of the assumptions both stated and implicit. Then I read on NASA's work on RCC repair and entry aerothermodynamics since the CAIB report was published. This work does not directly address 107, but the results of it invalidate the assumptions from CAIB. It's as simple as that. I think the odds of this working are about 1% at best. It still doesn't address the problem of what the EVAing astronauts are supposed to hold onto while they are putting stuff into the hole, or the fact that bags of water will boil and explode as soon as they get depressurized in the airlock, or water coming out of some sort of jury-rigged hose is going to emerge as a spray of superfine droplets, not come out as a stream that will flow into the hole. You might be able to get the hole filled in with the hose, but it would be anything but smooth, and you'd have chunks of ice around it that would break free and do more damage as heating started on reentry.
