STS-117 (13A) Mission- Part II

Have you heard any talk about ground microwave computer communication interference? <div class="Discussion_UserSignature"> <p><br /><strong><font size="3" color="#3366ff">Columbia and Challenger </font></strong></p><p><strong><font size="3" color="#3366ff">Starships of Heroes</font></strong></p> </div>

Microwaves wouldn't penetrate the metal walls well at all. Anything powerful enough to do that from the ground would be noticed from its other effects. And ISS moves so fast it is over the local horizon in just minutes.

How many contingency days they got now then for re-entry?

 

[bobblebob]

How many of those 3 computers need to be active at once to keep the ISS in orbit and with power? As we all know, computers arent the most reliable of things at times

 

[MeteorWayne]

One on the Command and control side, and one on the Guidance and Navigation side.<br /><br />Both functions have 2 redundent computers (3 "lanes" for each function) <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

The current plan allows two days for landing weather. There is 18 hours beyond that.<br /><br />They are implementing a power and resource conservation plan to try and stretch that 18 hours to a full extra day.<br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

It appears that the loop in the wire has corrected itself. <br /><br />That's a good deal indeed.<br />More retraction in an hour or so.<br /> <div class="Discussion_UserSignature"> <p><br /><strong><font size="3" color="#3366ff">Columbia and Challenger </font></strong></p><p><strong><font size="3" color="#3366ff">Starships of Heroes</font></strong></p> </div>

All computers in the FGB are off now.<br />That ain't good <img src="/images/icons/frown.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Yikes. This keeps getting better and better...<br /><br />SFN is kinda irking me. Their mission status center is really behind... <div class="Discussion_UserSignature"> </div>

Well they don't have a dweeb like me sitting there listening to every word <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.

[bobblebob]

How long can they be offline for before we start to see some serious issues with the ISS? <img src="/images/icons/frown.gif" /> <br /><br />Hope they didnt let Microsoft builld them, no wonder they broke if they have <img src="/images/icons/wink.gif" />

 

[MeteorWayne]

I think things are getting dicey, but am not sure.<br />If I heard things correctly, they are going to wait until the orbits translate westward enough for repeated passes, which will be tomorrow morning?<br />So I guess they can survive until then.<br />But I also recall that the Soyuz batteries were rather depleted, and am unsure about how long they can go without recharging before it's a major problem.<br /><br />In this case we will need to rely on those who know more about the systems, than what I have been able to glean from my understanding of the translated and garbled transmissions. <br /><br />EDIT<br /><br />Next mission Staus Briefing at NET 6PM EDT (2200 UT) should answer these questions, if nothing breaks before then. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

"Cause? Well, this has never occurred before, so it would seem likely that something that has changed in the last few days is the cause. It is unlikely that a hardware failure would occur simultaneously on all 6 pooters, ditto for a software failure"<br /><br />Could the added power going to the ISS have fried the computer hardware in some way?

 

[MeteorWayne]

Possibly, that's one thing they are examining.<br /><br /><br />UPDATE...not on the schedule, a Mission Staus Briefing will be broadcast on NASA TV at 2:30 PM EDT, in about 20 minutes. <br /><br />Edit: That may not be a good sign. Hopefully my gut is wrong.... <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

[bobblebob]

Thanks for the notice.<br /><br />Really hope it isnt power that has fried the hardware. They're screwed if it is <img src="/images/icons/frown.gif" />

 

[MeteorWayne]

They said earlier (last night?) that there was no evidence of a power spike.<br />But if all FGB computers are shut down till tomorrow morning, there be some scrambling goin' on.<br /><br />I hope I heard things wrong (which is possible; like I said, I was listening to the translation, and during what they call a "ratty audio" period) <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[bobblebob]

From wiki<br /><br />"The FGB provided electrical power, storage, propulsion, and guidance to the ISS during the initial stage of assembly. As other modules with more specialized functionality are constructed, the Zarya's role will primarily be storage, both inside the pressurized section and in the externally mounted fuel tanks"<br /><br />What is the primary role of the module to date?

 

[Testing]

Please keep the updates comming, I can't get it from work. Does not sound good, unplug the new panels? Problems I have here are trivial compared to this. <div class="Discussion_UserSignature"> </div>

 

[MeteorWayne]

From what they said yesterday, the module's computers are in control of the Elektron Oxygen generetors, CO2 scrubbing, moisture removal, power transfer to the FGB, as well as Guidance and Navigation for the ISS when the SHuttle is not there. Sounds pretty important to me.<br /><br /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

http://news.bbc.co.uk/1/hi/sci/tech/6752459.stm<br /><br />BBC article on it. It must be big issue to get on the bbc site <img src="/images/icons/blush.gif" /> <br /><br />Annoys me aswell that they mention Columbia on every report they do

 

[MeteorWayne]

Sounds like a repeat of what we've had here, other than I forget to mention the 56 day oxygen supply.<br />I did know that, but forgot to throw it on the pile <img src="/images/icons/smile.gif" /><br /><br />Of more concern is that if they lose control of the stations attitude, when the shuttle leaves, everyone else will need to be close behind.<br /><br />However it's "just" a computer problem....so kick the bloody thing, and fix it.<br /><br />MSB under way live on NASA TV<br /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

PRetty good MW.<br /><br />Real quick (and in random thought mode):<br />Some of the systems can run without computers.<br />These are SM computers, not FGB.<br />We can't power on FGB power converters withouta computer.<br />They had one for a little while so FGB has power again.<br />We could not undock the orbiter at this point since Russian thruster control is required.<br />Not a power spike. Maybe dirty power but the US specialist don't think it is. But we are trying to help.<br />Not microwaves from the ground.<br />This HAS happened before where all there computers would nto stay up but it was related to bad software.<br />I have had 2 hours of sleep in the the last 2 days and sorry I can't post more - when get time.

 

[bobblebob]

"this isnt too off nominal"<br /><br />i beg to differ, but clearly it is <img src="/images/icons/laugh.gif" />

Thank you. But they said they were unable to reboot this time. Ouch. <div class="Discussion_UserSignature"> </div>
