Thanks najaB. It was a good briefing at 2:00 pm.

SpaceKiwi · Apr 5, 2005

Thanks najaB. Hopefully there will be some re-screenings during the evenings, my time. <div class="Discussion_UserSignature"> Who is this superhero?

I didn't catch all of the 2pm briefing, but I managed to catch the ELVIS project manager's presentation. 103 cameras!!! There's not much chance that anything will slip past them this time. <img src="/images/icons/smile.gif" />

That's a lot of tape to review!

Just finished watching a re-screening of the 'Managing Hazardous Debris Briefing'. Extremely informative, but not really added to by some of the media present. I think they seriously need to consider a brief 'competency test' for attending media, before they are permitted to ask questions of the panelists. One 'journalist' asked how big a piece of foam would be allowable off the bi-pod ramp, having presumably just sat through the presentation where it was clearly explained several times that the ET redesign had removed the bi-pod ramp! And Marcia Dunn is it.......she had a couple of panelists noticably counting to ten in their heads! SRTF, you need to get over there! I have little doubt you would improve the standard of questioning significantly. The size of the explosive bolts for the SRB/ET connect were awe-inspiring though. It's incredible to believe that small diameter of metal can hold the stack together beyond T-0. Truely amazing. <div class="Discussion_UserSignature"> Who is this superhero?

Saw it too mate. Using some of the quotes for an article, but yes, wasn't the questioning rather bland!? It's respectful to ask probing questions - providing the motive is correct and imformative. People care and want to know.

>The size of the explosive bolts for the SRB/ET connect were awe-inspiring though. It's incredible to believe that small diameter of metal can hold the stack together...Uhm...you sure you aren't confusing the SRB/ET connect bolts with the ones that hold on the bolt-catcher? The bolt catcher bolts are the ones being increased from 3/8" to 9/16" (or whatever it is), the actual bolt was the big-ass thing that the presenter didn't dare lift up - the half that flies into the bolt catcher weighs about 31 pounds!

SpaceKiwi · Apr 6, 2005

No, not confusing the bolts! I meant the half a bolt he had on the left hand side of his little display table. As someone who is not a materials engineer, and has no real knowledge of how big these things should be, I didn't think it was big at all! Well, certainly not as big as I imagined it might be, and certainly not big enough not to disintegrate at the first sign of thrust from the SRB's! <div class="Discussion_UserSignature"> Who is this superhero?

SpaceKiwi · Apr 6, 2005

Yes, agreed SRTF. I couldn't get over Dunn though, looking for a black/white-covers-all-scenarios size for foam shedding. I thought all the panelists were great in carefully explaining that debris shedding and debris hits is not a black/white issue. Speed versus air density versus area of the ET doing the shedding. Even a non-science novice like me could understand the problems they had in trying to accurately model various scenarios. I wonder if some of these journalists have drawn the short straw in covering NASA? Perhaps they wanted to be entertainment reporters or something, and got stuck with space/science. Dunn was just looking for a 'sensationalist' headline I thought, a quick-fix angle to base her story around. And, the guy with his bi-pod ramp foam shedding must have been asleep for the previous half hour, especially when the woman from the ET program was speaking! <div class="Discussion_UserSignature"> Who is this superhero?

Watched the '114 Mission Overview Briefing last night. Well, not all of it as it was late and I fell asleep part way through the lead ISS Director's presentation! An issue came up which may have been covered in the eventual journalist questioning, but the guy reviewing the timeline for on orbit operations mentioned that the '114 EVA's would be conducted out of the Orbiter lock because there is a problem with Quest. Does anyone know what the problem is, as I don't recall reading about it? <div class="Discussion_UserSignature"> Who is this superhero?

SpaceKiwi · Apr 7, 2005

Aaaah, thanks news. I knew about the problems with the US suits on station obviously, but hadn't heard that they might have traced it back to Quest. That's interesting, I assume they are working the issue and think they have a solution pegged, as I note Expedition 11 is scheduled to perform an EVA in the US suits. <div class="Discussion_UserSignature"> Who is this superhero?

""Today was my first day back since my medical leave."" SG, congratulations on being back in the saddle as it were! Hopefully that will be the last time you view the inside of a hospital for a very very long time. <div class="Discussion_UserSignature"> Who is this superhero?

I read this thread in time to catch the Thermal Protection System Repair Techniques Briefing - JSC (Interactive Media Briefing). There are 3 systems for tile repair a one-part fluid and a two-part fluid; the latter is dispensed from a backpack through hoses and mixed at the nozzle. If the gouge is really deep (some tiles are several inches thick, 4 or 8 not sure) they have various shaped bags of what look and feel like cotton balls that they plan to use to fill the void up to the depth they can use the fluids. They have pins, like very thin knitting needles, that they push into nearby tiles, low in the holes, sideways, to hold the bags from floating away while they get some more. The other is a patch and gasket that they screw down with flat-head screws called augers (I think) right into the nearby un-damaged tile. They tested applying them while wearing space suits in vacuum chambers. The two-part bubbles a bit. After the cure in vacuum they put them in some kind of plasma jet machine and simulated reentry temperatures then showed us cross-sections. It was pretty good and the presenter was way easy to watch. For the RCC there was a different person and there are two repair types that can do holes up to four inches in diameter. They have an idea to use some existing screws to hold a wrap type patch for larger areas but they aren't flying that this time; they are having some trouble sealing the plasma on this type. One method is a one-part fluid and putty knife; they have to aim the RCC at the sun to heat it up to about eighty fahrenheit for that. The other is is the "plug"system which has a flexible carbide compound disk about six inches in diameter and a toggle bolt through the center of it. It looks like a very thin makita grinding wheel, and it is warped toward the toggle bolt side, like you took a DVD and heated it up and let it mold around about an eight inch diameter pipe. As you tighten the screw the plug is pulled down over the <div class="Discussion_UserSignature"> </div>

" nitrogen powered caulk gun. I'll bet somebody sells those at ACE someday" Damn right Bob, sounds like a really good idea that would sell! Could be another space industry spin off. *cough* somewhere back a year or so, iI suggested a silicone/chalking gun apparatas(sp) <img src="/images/icons/smile.gif" /> *(/cough) * PS, Shuttle_Guy....good to see your better! And good work you and the team at KSC have done to get us back on track. Many thanks from down under! <div class="Discussion_UserSignature"> ----------------------------------------------------------------- Wanna see this site looking like the old SDC uplink?Go here to see how: SDC Eye saver </div>
