So they can access the ECO's from outside the tank? <br /><br />I know you must be a little disappointed SG and frustrated that all of the NASA Bashers are starting to drum.<br /><br />Do you have a rough % of the chance for launch on Sat? or will it more than likely (from what you know) be delayed until next week?

><i>The LH2 low level sensors are in the feed line going to the orbiter.</i><p>I think that's the second time you've had to correct me on that. I dunno why it doesn't stick. <img src="/images/icons/blush.gif" /></p>
Does the problem have exactly the same symptoms as the previous ECO failures or is it something similar but not quite the same?
So s_g, as a professional, what are your views on how likely it is that we'll get off the ground in the july launch window?
*glomps the RTF bear*<br /><br />I so would but I don't think I can afford time off from school ... I took a couple days off last January to go on a road trip with friends and fell completely behind. And that wasn't even as cool as a launch would have been! Plus I really don't want the mission to be delayed until September 
<font color="yellow">"I respectfully request that you tone your remarks down a bit "</font><br /><br />OK I guess because of being frustrated by the scrub my wording was poor, sorry about that. I do and did understand that there were probably lot of <i>technical</i> reasons for doing that test now and not before. But it's not a purely technical issue, more like PR or image. <br /><br />Two events in the Launch Scrub News Conference highlighted this. First the Italian reporter asking a general question is the shuttle just too complex because the two recent mishaps (window cover, sensor fault). The second and more clear was the question about authorization for go flight while knowing that there are some untested issues. IIRC this was the one where Griffin intervened. The answers by the NASA staff were of course quite valid, because the source of the bug is still unknown they did what they could changed pretty much everything and decided to try with that, knowing that if the sensors still act they would notice it during countdown tests. <br /><br />Then Griffin started talking how the phenomenon is intermittent, it comes and goes. I don't know if he meant this as some sort of justification to the go flight decision or not, but if it was isn't it rather poor one? How does a test verify that intermittent sensor fault has been solved? How do you know if the problem is gone while you test but comes back the second you launch if you don't know the root cause for sure? What happened now is that NASA brought untested machine to the launch pad with fixes that they were uncertain of, hoping that the bug didn't show up during countdown. If that is NASA way of business as usual then .. oh well, it is.<br />
I tend to agree with SG...old hardware vs. new hardware. <br />The sensors are new so the likelyhood is that the problem is with the older transisters.<br />I'll keep my fingers crossed.<br />Based on SG's data, I have a feleing that Mission Managers are downplaying the possible launch date to avoid more bashing by the media.<br /><br />A quote from Star Trek...<br /><br />Kirk: Scotty, how long before we have Warp Drive.<br />Scotty: 3 days.<br />Kirk: How long would it really take?<br />
SG...will you have to wait until tomorrow afternoon after the ET is "inerted" before you can do any troubleshooting tests?<br />Or is there anything that can be done before that?<br />
So, not only does the problem come and go, it keeps changing place. A nasty one <img src="/images/icons/rolleyes.gif" /> <br />
Bad <b>bad</b> Lunatic!<br /><br />Btw are you positive about the LOX sensor, everybody up till now including www.nasa.gov speaks of fuel sensor.
Actually, grooble all but admitted it is his doing because he doesn't want to pay up on the $10 bet you guys had. I think he's sneaking in at night and "massaging" the flight hardware with a spanner.
Good job, SG! The delays are alarming, but what it's worth to calibre, I would rather be waiting for the delays than go right off and fail.

Can I get odds on Sensor #1 pooping on our party before Discovery gets to LEO?<br /><br />I was fairly depressed about the whole situation on the drive into work but, having read the dialogue here, I have decided to change status to 'cautiously optimistic' they can isolate the problem before the window ends.<br /><br />In all seriousness, maybe they should look at Sensor #1 at the same time before it has a chance to play up in a subsequent launch attempt. <div class="Discussion_UserSignature"> <p><em><font size="2" color="#ff0000">Who is this superhero?

Miles O'Brian just said that in all likelyhood the shuttle will be rolled back to the VAB to fix the problem and that it would probably look like a september launch...<br /><br />any word on this Shuttle Guy? or any new news?
Talk about transistors and heart failure, hopefully the launch will resume on July 16, even in september, err lets make it a happy infinity day!! <div class="Discussion_UserSignature"> <font size="0" color="#10bdee"><strong>A dazzling bluish luminosity from A distant south pacific.</strong></font><p><br /><img id="cb51e87e-8221-424c-8ff2-78c95122196c" src="http://sitelife.livescience.com/ver1.0/Content/images/store/11/15/cb51e87e-8221-424c-8ff2-78c95122196c.Large.jpg" alt="blog post photo" /></p> </div>
Do you think it has anything to do with upgarded sofware on the STS-1? <div class="Discussion_UserSignature"> <font size="0" color="#10bdee"><strong>A dazzling bluish luminosity from A distant south pacific.</strong></font><p><br /><img id="cb51e87e-8221-424c-8ff2-78c95122196c" src="http://sitelife.livescience.com/ver1.0/Content/images/store/11/15/cb51e87e-8221-424c-8ff2-78c95122196c.Large.jpg" alt="blog post photo" /></p> </div>
I'm a little confused - which of the sensors failed today, and which failed during the tanking tests? Did both LH2 and LOX sensors fail today?
><i>Did both LH2 and LOX sensors fail today?</i><p>According to shuttle_guy, it was the LOX line sensor.</p>
Ok! I heard the lox sensor mechanism of STS-114 stays identical as STS-1, only the software has been upgraded! <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <font size="0" color="#10bdee"><strong>A dazzling bluish luminosity from A distant south pacific.</strong></font><p><br /><img id="cb51e87e-8221-424c-8ff2-78c95122196c" src="http://sitelife.livescience.com/ver1.0/Content/images/store/11/15/cb51e87e-8221-424c-8ff2-78c95122196c.Large.jpg" alt="blog post photo" /></p> </div>
At the press conference, someone asked the question if the ECO configuration had changed over the years or if it was basically the same all the way through the program. The answer was that the basic design of the physical mechanism hadn't changed, but that there had been many software updates.
