<font color="yellow">Any idea of model #? </font><br /><br />No, not even sure that is what they have. Only a picture of it. They also have a power supply and function generator in the electronic repair kit. <div class="Discussion_UserSignature"> </div>

Thank you Wayne for the laugh as car is in the shop for waterpump. Yes, I could have done it myself but this is the first car I have owned that I do not work on. Sideassed V6 FWD Lincoln. $445 waterpump. <div class="Discussion_UserSignature"> </div>

Isn't it amazing A few decades ago I could stand next to the engine inside the engine compartment and change the water pump for 20 bucks in an hour. <br />LOL <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

<font color="yellow">I will find out on Monday (if not before) what the recommended calibration interval is. </font><br /><br />For regular guys like me the stickers all come back as being good for a year.

[MeteorWayne]

There you go making sense, bobw <img src="/images/icons/smile.gif" /><br /><br />The actual cal interval could be 2 years depending on the specs for the instrument...or even 3. Or 1.<br /><br />Without knowing the model, it is all conjecture.<br /><br />Although in the context of the current (that's a joke son <img src="/images/icons/smile.gif" /> -Foghorn Leghorn) situation, I doubt any of it is relevant. <br /><br />Edited for humor... <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Now what was it someone said about how you don't need a EE on board to diagnose these problems? <img src="/images/icons/smile.gif" /> If Anousheh was on board this flight she could show them how to do it. <img src="/images/icons/smile.gif" /> Damn tourists, poking their nose in...<br /><br />Ok, so we don't need a EE on every flight. How about a union licensed electrician and a plumber? The day will come they wish they had those. <br /><br />Or as MW suggested, some training on how to do these basic things. Something beyond "Righty tighty, lefty loosey". <img src="/images/icons/smile.gif" /> Red is for hot.. I am amazed. Bet they can't read a resistor code either.

Hi again!<br />Thanks for bringing the fresh news - I read with great interest.<br /><br />Here is something from the russian-speaking side of the net:<br />16.june.2007 RKK "Energia"<br />...<br />On 14 of july(prob. june) president and general constructor of RKK "Energia" N.N.Sevastjanov assembled operational-technical commitee, which included company specialists. During the 48 hours period after occurence of the abnormal situation, special measures were designed and performed to resume operation of station computers.<br />Through the night of 16 june (MoscowTime) with the combined efforts of RKK"Energia" specialists and ISS crew - the operation of 4 of 6 station computers was resumed. Power sources are connected non standart way. Another two station computers specialists use for analizing and evaluation of the primary reasons that created the abnormal situation. Later an attemp would be made these two computers to be switched on too.<br />For completion of the developed technical routines for complete recovery of station computers, a delivery of additional apparatuses is planned on the next russian cargo ship "Progress M-61". In that context operational-technical commitee developed proposal, to commence lalunch of the cargo ship two weeks earlier than planned (23. july. 2007)<br />

I have to disconnect for a while, or my brain will explode.<br /><br />I'll be back when I have processed this unbelievable situation <img src="/images/icons/smile.gif" /><br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Ground Control to Meteor Wayne:<br /><br />The display is unstable.<br /><br />Hang in there, bud. <div class="Discussion_UserSignature"> </div>

 

[bobblebob]

Did they successful connect everything needed to allow the new array to rotate and track the sun, during EVA 3?<br /><br />Seems that with all this computer failing business going on, its hard to find info on the actual mission itself

 

[bobw]

I think they have to remove some more launch locks tomorrow. <div class="Discussion_UserSignature"> </div>

 

[colchadisatlend]

Well, looks like another typical Atlantis mission.....with Atlantis kicking major ass as always! <br /><br />ATLANTiS RULES!!!!!!!!!<br /><br />She even bailed out the space station when its computers were down. While it seems challenging, it's a piece of cake for Atlantis. <br /><br />I have a question regarding something I read recently about landing options....an article made a very brief mention that if the mission needed to be extrended further that it already has, several "International landing sites" would be considered as possible main backups??? Is this true? And if so, where are some of these international landing that sites that would mainly be considered?<br />

[erioladastra]

Status:<br /><br />- computers are back up and most systems are back on line<br />- We know what went wrong on the computers but not yet why. Nothing is panning out. A computer failure well before the mission may be related. Soyuz uses the same computer so could be susceptible as well (but it has been off and can be flown manually)<br />- Apparently the same problem happened on Mir.<br />- Yes, we have been looking at stretching to the last possible moment to undock to help with attitude control and then land ASAP. So international site might be needed but only in a real contingency since that would set the program back big time.<br />- Computers with modified filters might be flown on the next progress which MIGHT be July now (at one time we even talked about using the LON shuttle).<br />- Way to control attitude without the computers still being worked<br />- Direct handover from orbiter VRCS and ISS CMGs now worked out and hopefully will work<br />- Not likely that we will extend the mission now but will see<br />- MT translation may not be done since concerns about momentum<br />- Many folks taking some time off to recharge before the end<br /><br />Big points now - more later

 

[erioladastra]

To answer a few more Qs I scanned quickly..<br /><br />- The p12 jumper was not demated during the EVA. We didn't think it mattered since it was not a powered connector but since we weren't sure we figured it wouldn't hurt since not needed until 15A. However, on the chance it was related we didn't want to demate it witht he computers up. More work is showing that the new element is not likely a cause but still TBD<br />- Normally all 3 lanes of the computers are on so this was not a latent failure not seen until another<br />- I did mis speak when someone asked about the DMS computers - yes it is the same used on Columbus, ATV, Soyuz, and the 3 SM computer systems

Sounds like they need a computer tech... Pick me I will go. I am computer tech network admin.. <img src="/images/icons/smile.gif" /> I have worked on computers in some strange places space station would be cool. <div class="Discussion_UserSignature"> <p><font size="2" color="#0000ff"><em>William ( deapfreeze ) Hooper</em></font></p><p><font size="1">http://deapfreeze-amateur-astronomy.tk/</font></p><p> </p> </div>

I saw the presser earlier today with Mike Suffredini which was very helpful in bringing me up to speed on the latest developments.<br /><br />A couple of questions/thoughts I have:-<br /><br />1/. What is the bottom line with the arrays versus the Russian computers? Are the arrays producing "noisy" power outside of the expected/designed tolerances?<br /><br />2/. Is the 'noisyness' of the power only going to get worse once the four sets of arrays are installed and in operation?<br /><br /> <div class="Discussion_UserSignature"> <p><em><font size="2" color="#ff0000">Who is this superhero?  Henry, the mild-mannered janitor ... could be!</font></em></p><p><em><font size="2">-------------------------------------------------------------------------------------------</font></em></p><p><font size="5">Bring Back The Black!</font></p> </div>

It sounds more like a grounding problem when you get right down to it. Maybe the static build-up added too much of a jolt when stuff was attached.<br /><br />Do they ground the trusses during a move?<br /><br />If all the trusses are the same noise should not be a problem. I would go with a transient voltage. Maybe the power was turned on too soon and the truss wasn't properly grounded.<br /><br />Grounding is a science in itself, sometimes the most inconsequential misstep becomes a major problem. Barely visible corrosion or minor defects can cause serious grounding problems. <br /><br />One simple solution is all composite construction, then you only get electrical connections where you need them. Much easier to sort out problems before you allow a connection than to deal with the problems after they have spread their terror way beyond what they actually did. <div class="Discussion_UserSignature"> </div>

I recall Suffredini mentioning a grounding strap on P6 that <b>hadn't</b> been removed on installation as a potential (through very unlikely) contributor to some of the difficulty. I believe he said it would be removed at some point in the future. <div class="Discussion_UserSignature"> <p><em><font size="2" color="#ff0000">Who is this superhero?  Henry, the mild-mannered janitor ... could be!</font></em></p><p><em><font size="2">-------------------------------------------------------------------------------------------</font></em></p><p><font size="5">Bring Back The Black!</font></p> </div>
