Before you post, read this: This thread is for live update of Flight Day 8/Special EVA-3 due to the addition of the OMS Pod blanket repair.
For general ISS problem comments, try to keep them in here: http://forum.nasaspaceflight.com/forums/thread-view.asp?tid=8402
Let's keep this one for the EVA, otherwise it'll get convoluted. Moderators will delete posts that don't comply to this (sorry :) )

and repair preview: http://www.nasaspaceflight.com/content/?cid=5133
About 22 presentations for OMS Pod repair in L2. We'll upload anything additional during the day into this opening post.
Other elements of EVA-3 will hopefully include additional 'hands on' help with the P6/2B retraction and installation of an external hydrogen vent valve on the Destiny Laboratory for the new Oxygen Generation System...although with EVA-4, priority remains with OMS Pod repair.

The truss structure could act like a huge antenna of course. Chaging the stations' shape leads to a change in their resonance frequencies.
Are there galvanic separations between the segments of the power supply?
What about grounding scheme?
I recall (without checking), that the US segment uses a pretty standard single point, floating ground arrangement. I remember that the Russian side of things isn't so clear cut....

Just re-reading some of the news reports last night I noticed that a symptom of the computer failure would lead to CMG saturation. I recall we were having saturation problems on this flight BEFORE S3/4 was actually mated. I'm wondering if there may be an existing problem. Perhaps the new ethernet cable may be the culprit after all.
EDIT: early morning typos...

That's exactly what came to my mind when the problem occured for the first time. If it's a kind of ethernet cable, why not try and pull the connector .... ? Even if it's not the source of the problem, it could be a necessary condition to it. Do you get the idea?

The CMGs saturate all the time even when the orbiter is not there! That's simply the nature of the CMGs.
The first sign of the computers starting to act up was when the S3 truss came in contact with the S1 truss, not earlier.
This has nothing to do with the CMGs.

Three questions:
Are the CMGs more sensitive with the added shuttle mass?
Can shuttle thrusters be used to desaturate the CMGs?
Did I hear right that the undocking of the shuttle can cause saturation of the CMGs?
1: Yes, more mass
2: Yes, that is what they have been doing
3: Not exactly cause it, but lead to a saturation if they don't have the Russian computers online so they can fire the Russian thrusters for CMG desaturation.

June 15, 2007. Korolev RSC Energia - MCC, Korolev, Moscow Region.
During deployment and connection of new solar array panels on the US orbital segment of the International Space Station (ISS), there have been some glitches in the on-board computers on the ISS Russian Segment (RS).
The computers were developed and supplied by European industry under an agreement between the European Space Agency (ESA) and Roscosmos. The computer were associated with unstable operation of secondary power sources. One of the possible causes is electromagnetic noise or power surges that occurred when new solar array panels were being hooked up.
RSC Energia and NASA experts are analyzing the data. RSC Energia has established a commission to investigate the causes of the on-board computer glitches and to develop recovery procedures.
The on-board computer glitches do not affect in any way the everyday life of the ISS crew.

If its accurate that the computer is now isolated from the US Segment power, then its difficult to see how the cause could be there. I of course know there could be radiative (EMI), but considering its space hardware it would have to be able to withstand at least a certain level of this. Even stuff for home and office use on Earth has to pass fairly stiff EMC testing, space hardware is bound to be even stricter.

The Nasa engineers are doing their jobs, how about the NASA pr. folks
This should be discredited before it gets out of hand.
Just a curiosity question, but have there been any new links to those computers that were installed on previous assembly missions and just now became active or increase functionality with the new assemblies.
Also , anyone if they know if they are working on any way to get telemetry to the Russian Engineers while the station is outside of ground station coverage, maybe using the NASA trds network.
I can't believe there is so much isolation between the US segements and the Russian segements.

A bit of goodness out of CNN at least: while the anchors are busy with the "they're all gonna die" story, Miles Obrien, their space correspondent, is talking about it not being that serious as there are work-arounds and fixes that can be done.
-
If this really is a noise or grounding issue, I should tell you that these types of problems are notoriously hard to track down. Tracing ground loops can be thought of like a Fraternity hazing for double-E's. This could be complicated on the station by the inability to just shut things down and unplug at will, and the apparent lack of double-E's or electronics techs on the crew.
I hope they get it understood quickly, and in that light I hope it's NOT a grounding or noise problem.

Abandonning the station, if attitude control is lost, would probably be permanent. I can't imagine NASA or RSA sending up crews to a station that's tumbling out of control. Seems like it would be too dangerous.
No, there's plenty of time to work on solutions before we start talking about abandonning the station.

It would be a bad decision, it would force congressional oversight, the mars global surveryer software snafu would certainly be brought up.

Don't mean to sound like I'm beating a dead horse, but in retrospect, are we sure the CMG saturation during install was simply an error on someone's part (not desaturating before the install, as was reported), or a symptom of a failure in the Russian attitude control system? It just sounds a bit too coincidental to me.
EDIT: JimO's comments got me thinking a bit more about that...

There are currently two Progress available to desaturate the CMGs that are independant of the troubled computers. With the CMGs desaturated attitude can be maintained. The biggest problem is the Atlantis demate which gives the station a large momentum change that will likely saturate the CMGs and will require a fairly large correction from the Progress. Once that is handled they should be in an OK config for a short time. Certainly until replacements can be flown up on Jul 23. If absolutely necessary they can evacuate at any time via the Soyus lifeboat.

Not to feed into the doom and gloom, but even de-manning the station and abandoninng it would cause a lot of problems. I'm going to guess they'd try to dock a progress or get someone back on there even if Atlantis has to leave before the glitch is fixed. That's a lot of mass to deorbit uncontrolled... I'm guessing a lot of those components would survive. Imagine the hit everyone's program would take if ISS came down over someplace populated... enough of this. Thanks for the package, Norm.

ok, adding even more to this argument.
Is there any option to just change-out , one or more of these systems or are they just that bulky, old, or integrated to do. These things do have logic boards don't they.
How about ground simulations using similar hardware, I hope the Russians are doing that.
new computers, logic boards , power supplies could be sent up on
on a progress, or even an emergency shuttle flight if they are too bulky.
And I can't believe if there was really a risk to losing a multibillion dollar station or a possible hit on populated area that The country wouldn't risk sending a shuttle.

Mike said that the CMG saturation was caused by "the truss being waved around" :D
In retrospect it seems like it would have been a good idea to insure the status of the CMG's prior to moving the truss (and perhaps they did) but they did have a deadline on getting it mated. So far as I can tell the CMG saturation was not a cause of the attitude control system failure.

I was actually saying it might be a symptom, not the cause of the failure. In other words: the problem was already there, and the issue with the CMGs being saturated before install was caused by whatever led to the failure. Admittedly, the CMGs have had their issues too.

Fair comment. Wouldn't they have these spares already on board?
With the sort of work thats going on with solar arrays and knowing the computers are sensitive to dirty power surely it would have made sense to position spares or even power down a couple of the computers in case one or more were lost due to power spikes/rfi/something else?

Aha! Finally a disclosure of something that must have been in work since shortly after the Russians weren't able to initially recover. If the computers were working before the power hookups were made to the new arrays, and they failed to reboot today after that power was demated internally, it must have lots of people thinking that the initial upset of the computers fried them to the point they're not recoverable.
f that's the case, the only options to maintain attitude control after shuttle leaves would be to devise a new way to command the Progress thrusters absent the Russian computers. Thus, find a way to tie them into U.S. segment computers and QUICKLY write software to have U.S. computers that are unaffected by this to assume minimal command and control functions of the Russian segment until new flight hardware can be brought up on a Progress.
Rather than demanning the station, this would seem to be the worst case scenario analysis they'd be working on while the Russians continue to attempt troubleshooting. The more time that elapses, though, with no joy on the computers has to have them thinking more and more that they're fried.
The other thought that must be in discussion - but we've not heard about so far - would be have EVA4 devoted to de-mating the connections that plugged-in the new array, which seemed to be the jumping off point for the computer issues.
This will be an interesting one to see eveolve over the next few days.

Detatching the new array's power couplings would likely be pointless.. the Russian computers did not come back up correctly even when they were decoupled from the US side of the station's power grid. They may've gotten fried whenthe array was first connected, but disconnecting the array now doesn't look to me like it would do anything to clear up the issue.

Those systems would have to be somewhat compatable to begin with, and I doubt that. I take it these aren't your average off the self computers.

You're probably right. Only thing I was thinking was there may be a trip circuit somewhere between interfact of the new truss/array and the internal circuitry in the node. If you unplugged the new power at its source, you'd eliminate that as a possibility.

I know in the auto industry there are groups devoted to running sneak circuit analysis(several commercial codes available) and monte carlo simulations based on possible variations for each component(and grounds) to check for "leakage" or "feedback".
I would think NASA would have their own team devoted to running such simulations.

This will really help you and me.
I'd like to echo this. It's going to be a very eventful FD for the repair and EVA-3 so this should be dedicated to that.
Please note this as we can't move posts between sections, so they'll be deleted.

Understandably, there has been some shuffling around of the EVA. What is the current plan for today? blanket repair first, 2B retraction, etc.?
EDIT: still combing articles trying to get a sense of the flow. I am unaware of the 2b retraction window for today as well...
-
the blanket repair and the hydrogen vent valve will be first; then the 2B retraction will be in work for the rest of the EVA.

OMS pod repair work will be done at the same time has the H2 vent valve installation on Destiny.
Then it's on to P6 and perform some EV assistance with the 2B array. And that's pretty much EVA-3.

Are they removing the last few launch restraints??

Briefing about to start.

No SARJ work scheduled for this EVA, jaredgalen.

I think the clearest way to do this would be to only post the updates, the news and so on that are given in the briefing, without starting discussion (solar array jettisoning, station evacuation, exotic plans to recover the computers...) about the new data given.
It's up to Chris to organize this, though, I'm only giving my view :)

Problem is that the Briefing will more than likely be non-EVA report. And even a small description could start off more talk here.
Better for someone to report in the other topic and get the topic fuel there to go.

Possibility of disconnecting the suspicious cable (one that will link S6 to the MBSUs on S1) because it won't be needed until STS-119, as early as this upcoming EVA.
-
power quality from 3/4 truss, on examination by oscilloscope, was fine - power source isn't the problem.
a russian secondary power supply (sensitive one) has failed (maybe hard), no response at all.
they're thinking about how to desensitize the sec. PSUs, checking off possible causes from the fault tree.
theyve noticed a connnector (runs thru 3/4 truss to provide power to truss 6) on 3/4, that after mating (on install), the Russians noted bus activity indicative of failure mode. They're thinking about disconnecting it on today's EVA just to rule it out as the cause of the problems. it's not needed until truss 6 is installed. They suspect this cable because the timeline fits. i.e., around the time it was connected, the problems started

Ok no Ku at the moment. but they did get out early which is good!
On to the setup then its off to the Nadit/Aft of the Destiny lab to get on the shuttle on.

Sorry everyone.. Its hard to tell whats going on without a picture.
I have a large status wall here that has the timelines and drawings of the tools so I can note them once I find my place here.

No Ku nor S-band. :(
S-band just returned. Ku could be back soon is my best guess.

Looks like 15 mins (approx) to Ku according to todays execute package.
Of course thats exclusive of any inhibits on the Ku antenna.

All I can tell right now without Ku or reference is that JR is near Danny.

Okay everyone, give me a few minutes to update my two-line tracking elements to track STS-117 during the orbital passes so my predicts are accurate and pull up the FD 8 execute package so I can check out the KU passes, I just joined the coverage as I have been busy doing other work this morning, just looking at the map on NASA-TV don't expect KU until the complex passes into sunrise as it moves northeast towards TDRS-West over the central Pacific ocean.

That is right, kneecaps, you have read it correctly, it is the white bars that show KU passes from the shuttle side, the station KU coverage should be similar. It is helpful to refer to this as you watch the EVA, then you know when to expect live video etc. The black bars are S-band (voice) coverage.

Just a note, we are 16 minutes away from leaving KU coverage on TDRS-West, and looking at the KU coverage on TDRS-East on this orbit (orbit 109) it looks BLEAK at least on the shuttle KU side, not sure on the ISS KU side, we will see what the INCO officer in MCC-H can provide us then for live video, just don't get your hopes up, I could be wrong and I hope I am.

-
5 minutes to handover from TDRS-West to TDRS-East (handover means we are moving out of communication range from one TDRS to another TDRS), may have a short KU pass with TDRS-East when the handover is completed but the KU coverage through the shuttle on this pass after 7 minutes from now does not look guaranteed, just a heads up!

We are now on TDRS-East KU coverage, not sure how long we will have it as I don't have a station KU timeline, only the shuttle's and I am not sure who is providing the KU right now (shuttle or station side), I think it is through the station KU as the shuttle KU for this pass is very poor.

We are now passing directly north of TDRS-East, passing over the north central Atlantic ocean towards Europe. As move closer to the ZOE and more east and south of TDRS-East we will start to lose KU coverage from it, sorry this will happen on every orbit. We probably have 15 minutes left of KU on this pass before we start the ZOE pass in 18 minutes, 13 minutes to sunset.

No it appeared on the OMS pod 60 seconds after launch due to wind pressure as the shuttle was passing MAX-Q, the SRB camera on the left SRB facing down shows it a black spec appearing at that time.

JR still having great success! Danny is quiet and having his staple run I think.
-
Expect to pass out of the ZOE and move under TDRS-West coverage in 13 minutes from now, DO NOT EXPECT KU RIGHT AWAY, the station complex will be moving south and east towards Australia and KU will not pick up again until the station "rounds the bend" and starts to move north and east towards TDRS-West about 30 minutes from now.

Success on upper layer!

Ok done with staples and on to the pinning!

Just a quick reference shot for sts1canada.

I'll put this question here because it's related to the Ku video and comms. When they say TDRS-W and TDRS-E, are they talking about 2 individual sats? According to my quick google search there are 8 satellites named A to H, and of course B was lost in STS-51L. So I'm puzzled.
-
Continue
-
Just a heads up, the KU should last on TDRS-Z until the time of sunrise as have I posted above, then we should have a small period of NO KU and then KU on TDRS-West, that is if I am reading the KU comm summary in the FD 8 package right.
16 minutes to sunrise, in TDRS-West coverage for another 53 minutes, should have TDRS-West KU in 20 - 25 minutes when this KU pass ends soon.

Passed out of TDRS-Z KU coverage, now in a period of ratty comm as I talked about earlier, this is normal as the station continues to move SOUTH and east away from TDRS-west which is to its northeast right now, as we "bend around Australia" and start to move north and east again towards TDRS-West, comm and KU coverage will improve, BE PATIENT this pattern will happen EVERY ORBIT! that is why I am calling out times to and out of ZOE, so you all know what to expect for KU.
5 minutes to sunrise, KU will resume sometime after sunrise when the complex is more line-in-sight with TDRS-West.

Question: Of what material are these staples made of? wouldn't the staples heat up during re-entry? And would this pose a threat to the thermal blanket or tiles?
-
TDR-E LOS was quite a while ago - I think you meant TDR-Z Richard... If you look at the attitude of the Orbiter - the way the nose is pointing 'up', AND the fact that there are solar arrays there too make me believe strongly that they are possibly interferring with the view of TDR-W at that time. KU - there are zones where it will not be allowed to radiate with the EVA on-going too....
-
The pattern for KU is simple to follow, moving north and east towards TDRS-West & TDRS-East, KU video coverage is good, moving south and east away from TDRS-West (like right now!) and TDRS-East, bad or NO KU! This pattern repeats itself every orbit.
Less than one minute to sunrise, next orbit will be 110!
Richard
-
Probably surgical stainless steel. NO and NO. Tests confirmed that no probs were expected.

broakhekke - 15/6/2007 8:47 PM
Question: the staples heat up during re-entry? And would this pose a threat to the thermal blanket or tiles?
No, they tested them and wouldn't of done this otherwise. Check the news stories in the first post of this thread as we have pretty much everything covered.
-
Possible Russian CPU restart in 10 mins!
-
Patterns may repeat, but blockages by either vehicle (orbiter or ISS) will cause the Ku-band to cease transmitting via SM Ops software control - nevermind the additional issue of EVA crewmembers in or very near the cargo bay area. RF hazards you know....
-
If I read the KU coverage properly, we may get some KU in 10 - 15 minutes as we move northeast more in sight of the TDRS-West.
Now in sunrise, 54 minutes left of sun in this pass until sunset at 4:44 PM EDT (8:44 PM GMT), this TDRS-West pass lasts to 4:24 PM EDT.

You are right Charlie, I was aware of blockage and KU RF hazards but I was trying to keep the issues of KU outages generic for those people who are new to the coverage and get frustrated when they see KU one minute and then lose it the next! Thank you for your insights, always appreciate them! Right now I am using STSPLUS to track the complex and it gives me the TDRS-E TDRS-W coverage times, sunrise, sunset times, but as for KU coverage it is my best educated guess after watching these missions for the past 30 years and past 20 years with more than two TDRS's in orbit.

You can see JR's shadow.

Good views of the pins.

Are some of those local tiles chipped, or are those just "clean" spots on the tiles? Note: I realize that if they are chipped, it really does not matter.

Are some of those local tiles chipped, or are those just "clean" spots on the tiles? Note: I realize that if they are chipped, it really does not matter.
They are a bit chipped, in fact, I saw a tiny piece float away right under the right most pin. If you look at the two pictures Zachstar posted above your question, you can see the difference.
-
Will the re-entry windstream pull those pins out..they seem to be sticking up a bit from the blanket ??

Nope, they will hold.

Yeah, I thought I saw him kind of flick a flaked piece away.

I feel bad for the poor technician that has to pull all of those out in the OPF. Get your leather gloves and wire cutters ready!
-
2:57 Min EVA so far.
I think out of 6-7 Hours max.
So Plenty of time for solar panel retract and maybe the launch restraints.
-
Wow. Terrific work in those gloves, especially in not letting any of the pins get away!
-
Were the tiles chipped prior to the EVA?
-
Messy OMS pod.

Charlie, yes it is neat, it is a DOS program that I am running under Windows inside a program called DOSBOX, it was made by the late David Ransom and I have been using for the past 10 years or so, it is available as shareware/freeware on the internet. Here is a screen shot of it, the iss/shuttle complex is the white mark on the orbit trace in the middle of the screen.

Mission: STS-117 - 21st International Space Station Flight (13A) -
S3/S4 Truss Segment Solar Arrays
Vehicle: Atlantis (OV-104)
Official Launch Date: June 8, 2007
Expected KSC Landing Date/Time: June 21, 2007, 1:52 p.m. EDT
Crew: Sturckow, Archambault, Reilly, Swanson, Forrester, Olivas and
Anderson
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles
Today is Flight Day 8 for STS-117 and Atlantis is docked to the
International Space Station. Crew members Jim Reilly and John Olivas
are preparing for the week's third spacewalk, a 6.5-hour excursion to
repair a thermal blanket on the orbiter and assist in folding up a
solar array on the station. On Tuesday, the crew unfurled the solar
array attached to the newly installed S3/S4 truss segment, which was
transported to the station on Atlantis. On Monday, Reilly and Olivas
conducted the first spacewalk to connect S1/S3 power cables, release
launch restraints and solar array blanket box restraints, and install
solar alpha rotary joint drive lock assemblies. On Wednesday, crew
members Patrick Forrester and Steve Swanson conducted the second
spacewalk, during which they helped to retract the 2B solar array
wing and prepared the solar alpha rotary joint between the S3 and S4
truss segments for rotation.
-
Thanks Zachstar for all the GREAT EVA pictures
-
You can see some of the pins.
-
15 minutes to sunset on this pass, about 25 minutes left of TDRS-East coverage on this orbit, 110, expect KU to drop out before we reach the ZOE in 25 minutes, the ZOE pass this orbit is 13 minutes long.
Richard

Yes, should be pretty obvious in the articles on the homepage here from the prior pictures.

-
JR moving to the top of the lab to await and assist Danny.
-
Under 11 minutes to sunset, 20 minutes to the end of TDRS-East coverage, probably have KU for about 15 more minutes until blockage occurs to line of sight with the TDRS-East satellite.
Richard
-
I suspect they will use the next day pass to start EVA array retract ops, I am pretty sure that they will want to do these array ops in daylight to watch the folds in the array and count the bays earlier. Speaking of the next day time pass, here are the times for it, sunrise on the next pass will occur at 5:18 PM EDT (9:18 PM GMT), remember sunset occurs now in 5 minutes at 4:44 PM EDT.
Richard
-
View of the payload bay.
-
Motion!
-
3 minutes to sunset, 13 minutes to the ZOE, expect loss of KU before the ZOE.
Richard
-
Did EVA1 already de-mate the connector they were discussing on the new truss?
-
bsegal - 15/6/2007 3:42 PM
Did EVA1 already de-mate the connector they were discussing on the new truss?
No. Last I heard that would be after solar array retract.
-
Danny reports how beautiful it is out there.
-
The next ZOE pass will be 13 minutes long starting at 4:54 PM EDT (8:54 PM EDT). We may have TDRS-Z KU again for this ZOE pass like we did on the last orbit 109, currently on orbit 110 for those following in the FD 8 execute package. We shall see, now we have sunset! 9 minutes to the ZOE.
Richard
-
3:20 EVA Duration.
Awaiting Danny to arrive.
-
6 minutes to the ZOE, 30 minutes to sunrise.
Richard
-
Danny arrived on the Lab
-
Moving out of KU range or having blockage with TDRS-East, which was expected, 4 minutes to ZOE.
Richard
-
Danny off the arm and they are heading back to the OGS worksite to reinstall the shield.
-
2 minutes to the ZOE, 26 minutes to sunrise, 15 minutes to coverage with TDRS-West with KU following around 20 minutes after that, we may get some KU through TDRS-Z in the mean time.
Richard
-
I see Joe Tanner there seated next to Megan. Undoubtedly for the solar array retract.
-
And they are at the site and working the reinstall.
-
Now in the ZOE, out of comm with both TDRS-West and East, comm through TDRS-Z.
Richard
-
Remember once again as we are in this ZOE, look at the map on NASA TV, when the complex moves south of Australia and then moves northward again and more east, KU coverage will improve again, that is about 25 minutes away , after sunrise occurs in 20 minutes.
Richard
-
8 minutes to comm coverage with TDRS-West, may have some ratty comm after this time, KU coverage as noted in my above post.
Richard
-
Ku!
-
jmjawors - 15/6/2007 4:54 PM
I see Joe Tanner there seated next to Megan. Undoubtedly for the solar array retract.
Also, I think he was the lead astronaut coordinating the tile repair tasks and did a lot of the mock-up tests.
-
Now receiving KU through TDRS-Z, comm with TDRS-West is still 7 minutes away.
Richard
-
Why is it the ZOE when you have TV and comm?
-
What cover are they working on - the vent valve R&R panel?
-
The TDRS-Z satellite is not always available to NASA for KU coverage during missions, as it is shared with other users of the TDRS network. It is made available to NASA if the schedule of its KU use permits from other users and NASA usually scheduled KU use through it during important times like EVA etc. Normally, this KU coverage is not available during the ZOE on regular mission days. I am sure someone else here can provide a better description.
Richard
-
12 minutes to sunrise, 2 minutes to TDRS-West comm available (no KU yet through TDRS-West, still on TDRS-Z).
Richard
-
Richard, Thank-you for the info on TDRS-X
-
This panel really seems to be giving a battle here.
-
According to the comm schedule in the FD 8 execute package, we should have KU through TDRS-Z for about the next half hour or so, so we should see sunrise with it in 9 minutes.
Richard

Not at all, I am just a space fan like all of you especially a fan of the STS program, I remember STS-1 when I was ten years old and I have followed every shuttle mission since then. You may notice that my forum name is sts1canada, sts1 stands for shuttle program being #1 and I live in Canada. I just like to follow the NASA TV EVA coverage and fill in the gaps of when to expect KU, sunrise or sunset times for those following the EVA so it is easier to follow, it's also fun, I hope everyone else enjoys my updates, the PAO leaves out some interesting details sometimes. Sunrise!

Ok getting a plan in place to set up Array ops.
JR is going up first while Danny works on the shuttle arm reconfigure.
-
This sun pass will last for 55 minutes, sunset will occur at 6:15 PM EDT (10:15 PM GMT), 42 minutes left of coverage with TDRS-West with some KU in this pass, and then 17 minutes to coverage with TDRS-East, we lost the connection with TDRS-Z as expected, should have KU with TDRS-West in about 15 minutes after we pass by Australia and move northeastward towards TDRS-West when we will have a clean line of sight with that TDRS. Expect ratty comm for the next few minutes, this is normal.
Am I beginning to sound like a broken record, I know I sound like I am repeating myself every orbit.

This could be a hugely successful day. OMS Pod blanket repair is getting thumbs up on review. The Russian (I know I shouldn't be saying it on this thread) Computer issue is looking positive now, and a retraction of the array would be superb (although 18 or so bays is a big ask).
And yes, no broken record, Richard, KU availability is important.

15.5 bays left at the last count. If they can work the array and retract it in orbital night, they should be able to get it down to about 5 or so bays.

Thank goodness these EVA's are occurring in the afternoon for me here in my part of Southern Ontario, Canada, I could never do these updates in the middle of the night. I have a couple of updates before I have to go away for supper for a hour so here they are:
Yes we expect KU on this pass under TDRS-West sometime in the next half hour (exact time unsure), 31 minutes of comm with West until a handover to East (which occurs in 4 minutes). Sunset is 43 minutes away, the ZOE is 60 minutes away and it will last for 12 minutes. There you go until I come back, keep up the great work everyone.
Richard

Just to clear it in advance, can we talk about the array retraction in this thread?

Hello everyone, it's the first time for me to follow the mission through Nasa-tv. I'm from Holland and i want to thank you all for the commentary you all give in this forum. i hope you'll understand my english, i speak it better then i write.

Pretty slow progress with all the preparation work now.

Assuming no rework needed on pod repair (nice work Danny) and good progress on the retract today, there should be LOTS of time in EVA4 for get-aheads, right?

No. There have been lots of time lost and EVA-4 will be needed mostly just to get S3/S4 ready to go.
If that gets done in an acceptable time then maybe they will have time for lots of get-aheads.
-
Finally! JR is on his way.

No. There have been lots of time lost and EVA-4 will be needed mostly just to get S3/S4 ready to go.
I am been following EVA-3 here (great coverage :) ) and on NASA TV, but do not really know where the time has been lost. Seems like many small annoying problems after the blanket repair.

They will need a 7 hour go at this rate. Just to get an hour actually at the array.

How long did they spend playing with tools at the Airlock.. 30 mins?

For sure not the most efficient EVA ever.

And Danny is on the truss.
Lets see what they can do!

Return of the "Hockey Stick" !!!

5 hours! 2 hours left if granted a 7 hour extension that will likely be cut short when a scrubber saturates.

Okay finally back after my own "LOS" (loss of signal) period with our forum coverage here! Just have some on and off KU coverage through TDRS-Z at the moment, 2 minutes to sunrise! Give me a few minutes to get organized again for coverage. Thanks for the great updates everyone!
Richard
-
Weird... how can we see the beams of light? Was there a waste water dump?
-
Sunrise!

This intermittent KU is probably caused by station blockage as we start to move away from TDRS-Z.

Joffan - 16/6/2007 12:50 AM Weird... how can we see the beams of light? Was there a waste water dump?
I was thinking the same, but it's probably a camera lens artifact. If you look closely, the lights are pointing almost perpendiculary from the "beams". I think those beams are just reflections.
-
Fluffing the array
-
We are in sunlight now and will be for the next 56 minutes until 7:48 PM EDT (11:48 PM GMT). We are back in TDRS-West coverage for the next 47 minutes and we should have KU through the West a little later in this pass, right now we still have KU through TDRS-Z if I look at the FD 8 comm timeline.

We have just moved out of KU comm with TDRS-Z as expected, I expect we should have some KU through TDRS-West within 10 minutes or so, so be patient, KU will improve as we move northeast of New Zealand.

40 minutes left of coverage with TDRS-West, 47 minutes to sunset on this pass, we will be on orbit 112 when we pass the equator.
Richard
-
OK.... how about this for a new rule... no more exclamation points for “ABORT!”
With this new careful retraction process, we’re going to have a lot of aborts.
-
Another!
Then Abort!
Not good at all!
-
13 bays ... out.. so at this rate and fluffs.. I make it a 2 hour job
-
Bet you the PAO never thought he would be talking about fluffing......he seemed pretty bemused at what he had said :)

Some fluffing and other work.
5:40 Duration spacewalk so far.

You could say that again!
-
The next ZOE occurs in a hour and ten minutes at 8:13 PM EDT (12:13 AM GMT) and it will be 8 minutes long on this pass.
Sunset now 42 minutes away, KU may be spotty for a while as the space walkers are working on the top of the P6 array and they may be in the danger area of the KU beam so the KU system will not be operating if the space walkers are near the beam's path.
Richard
-
Next Retract and we still have no Ku
-
Retracting one bay.
EDIT: Not a full bay, I'd think... abort was called to fast.
-
Abort!
But we got Ku now.
-
Retract!
-
Danny fluffing is a lot quicker than the work done by RJ.. I think if they wanna get this job done.. then I would outsource the work to Danny and let RJ do the reports from his view on the arm
-
Abort! Dang this is going slow!
-
As the complex moves northeast away from TDRS-West and hand overs to TDRS-East, our KU coverage MAY improve if the KU antenna points AWAY from the P6 work area where the EVA crew is now (ya, and now that I say that, KU reappears!)

12 bays remaining.
Consumables looking good.

Now moving into comm coverage with TDRS-East, we will be losing comm & KU with TDRS-West within 23 minutes, should have additional KU with East after that time, now a little over 30 minutes to sunset.

Fluff on the right and left
The aborts are expected. That's the whole reason for the EV assists.

T minus 10 WAFERS and countng (estimate)
It's going to be close, but I reckon it's doable if the retracting behaves.
-
That was the longest retract yet, 19 seconds long!
-
You know at this rate they may get this array retracted before the ZOE that we pass through in 44 minutes, 9 minutes left of comm with West, 16 minutes left to sunset on this pass, final array retraction may occur in darkness.
Richard
-
It will be close and we may not have Ku when it happens but they may just get it done!
7 bays left!
-
Estimate of 7.5 bays to go.
-
Wouldn't it be easier that both astronauts would have one tool for both tasks? Couldn't NASA design a hockey stick with that scrapper thing on the other end?
That way both astronauts could perform both tasks!
-
JR making his side REALLY nice and liquid.
We may have a really good chance here!
GO ATLANTIS! GO EVA-3!!
-
I don't think we are going to have KU unless we are lucky, we are either going to have KU and darkness for final retract or no KU and darkness for final.

Danny fluff the right.
Plenty of time left but low day left :(
-
Next WAFER in work...
JR comming in
-
5 minutes to loss of TDRS-West comm, loss of KU through West due to line of sight and station blockage issues, we are under comm of EAST, KU has returned but it may disappear again as we move out of TDRS-West comm coverage.
Richard
-
Here comes another retract!
Retract!
Good Motion!
Abort!
JR is coming and hangups are gonna pay!
-
2 minutes to loss of TDRS-West (possible KU loss at that time), 10 minutes left of sun for this pass, heading for a night pass soon!
Richard

Fluff right
-
Pretty "old" wire.
Here comes DANNY!

MET for the STS-117 mission is now exactly 7 days! We appear to have KU now through TDRS-East (which is good!) but sunset is 6 minutes away! We are 33 minutes away to the ZOE and expect the KU to drop out before we reach the ZOE.
Richard

Zachstar - 16/6/2007 1:43 AM Danny really earning his pay!
It must be really tiring, having to go around that BGA every time the arrays need fluffing, with all the tether changing and holding to the handrails.
-
Sunset!
-
1 minute to sunset, 28 minutes left to the ZOE, next sunrise will be in 35 minutes from now.
Richard
-
nightvision on!
-
Notice How Danny is basically a statue to save consumables.
They really want this done NOW!
-
If they get this retraction done is there a need for EVA-4?
-
Orbiter Obvious - 15/6/2007 6:48 PM
If they get this retraction done is there a need for EVA-4?
Yes to prepare S3/S4 for rotate. Also lots of other tracks.
-
WAFER in work.. half bay
-
1/2 a bay retract coming.
-
Right is good.. left needs a Fluff
-
25 minutes to the ZOE, sunrise will occur at 8:20 PM EDT (12:20 AM GMT).
Richard
-
Retract!
Good Motion!
Abort!
Just Cleared!
But wants to do some fluffing regardless.
-
End game.. 1 bay then latches
-
45 mins.. to play
-
WAFER's Away.. very short
-
In case anyone is wondering why I keep mentioning the ZOE, our live KU coverage will be interrupted before we enter the ZOE so when I say we have 25 minutes to the ZOE, that usually means we have about 20 minutes of good KU video left on this pass.
Richard
-
Powering up for retract!
45 Mins remaining of solar array time!
Power up
GO GO GO!
Retract!
Good Motion
Abort!
Left Outer!
JR Comes in do deal damage on hangups!
-
20 minutes to the ZOE, 27 minutes to sunrise, anyone want to guess whether this array will be retracted by sunrise (8:20 PM EDT)?
Richard
-
Your updates are really helpful sts1canada THANKS!
6:50 Hours into the spacewalk.
Strange how it almost seems natural now!
You don't hear the air sound alot.
-
I'd say not retracted by sunrise; they might have the blanket box unlatch in work by then
-
Danny and JR did good!
Power Up!

Really looking good!
-
As the complex is heading towards the ZOE, it's angle to TDRS-East is very diagonal which is turning out great for us for KU coverage, we should have KU for a little longer than I expected but I make no promises when it comes to KU predicts!
Richard
-
Looks like just over 4 bays to go
-
Danny goes right and left to deal punishment to those terrible hangups that cost time!
PAY! (*FLUFF*)
-
14 minutes to the ZOE, 20 minutes to sunrise!
Richard

Powerup!
Standby!
Ready!
RETRACT GO!
Good Motion!

Danny calmly continues to deal punishment!
-
The way things are going (which are good) it looks like the final retract may occur very near or in the ZOE, it is only 12 minutes away!
Richard
-
Nice .. 1 Bay
3 bays to go
-
1.5 bays to go..it looks.. power up and go..
-
About 10 minutes to the ZOE, still hanging on to KU from East.
Richard

6:44 EVA Duration
Latch Inspection
-
Latch inspections in work.. JR needs to come out
-
5 minutes to the ZOE, we will lose KU soon for a short while. There it goes...
Richard

I hope ground makes em wait till they have Ku :(
Reference Orbit
-
Command to unlatch..
-
Sending Unlatch commands!
-
2 minutes to the ZOE, out of KU comm with TDRS-East, may get KU through TDRS-Z again during this 8 minute ZOE pass.
Richard
-
4/4! Left!
-
We have Ku!!!!
-
We will pass out of the ZOE and enter TDRS-West coverage by 8:22 PM EDT (12:22 AM GMT), sunrise expected in about 6 minutes. We may get KU from TDRS-Z and there it is, KU through TDRS-Z!
Richard
-
4/4! All done and good!
-
No EVA-Air sound as they stand like statues saving every last precious min to get this job done!
-
Half bay comming up..
-
Just a note, this KU pass will not last long as we move south and east away from TDRS-Z, enjoy it while we have it, sunrise in 3 minutes!
Richard
-
How does weightlessness affect the exertion required to effect a physical task?
As I understand it, when you push or pull on an object the law of inertia still applies (mass is unchanged). But what does it actually mean for the person doing the work? Can they lift heavier objects than down on Earth?
Apart from the sustained mental concentration required, how taxing is an EVA? Is it backbreaking labor?
-
Power up!
Half Bay retract!
HERE WE GO #1
GOOD RETRACT!
Waiting for final go for final retract!
-
Now in the middle of the ZOE, sunrise is occurring now!
Richard
-
Wait 1 min for telemetry.
Sunrise!!
-
1 minute to TDRS-West comm pass handover! leaving the ZOE, KU still through TDRS-Z.
Richard
-
EVA is apparently very difficult, but due to having to work against the internal pressure of the space suit rather than zero-G effects. The US and Russian suits are different in this regard, as the US suits run at a lower internal pressure which requires prebreathing pure oxygen but makes it easier to work.
-
Hopefully we will see the final retract and latching on KU before we lose KU from Z!
Richard
-
Just waiting on the final retract call. This is it folks! The moment we have been waiting for!
When ISS will start to look like the final design!
-
Quater bay comming up..
-
Oh a quarter bay retract first!
-
Interesting... so does it feel like moving in molasses?
And again, can you lift heavier objects in space?
-
GAH lost KU!
Power up!
Retract!

Not the correct thread! Please ask this question in the Shuttle Q&A thread.
-
Sunset is now 55 minutes away, just lost KU from TDRS-Z as expected and now it is back probably due to station blockage.

That is how we do things downtown.... or in this case, uptown.
-
BEAUTIFUL! Excellent job everyone on EVA, shuttle and station, MCC-H for final SA P6 retract and everyone here for your coverage!
Richard
-
Awesome! Let's hope they re-extend alright after P6 is moved, which, I believe, is due in about 4 months!
EDIT: typos again... :)
-
Good Job EVA-3 you deserve a good rest!
A BRIGHT future for the ISS
-
Good job !
-
Really awesome.
Now! When does the radiator get retracted?
-
great day in orbit.... 7 hrs 9 mins
-
45 minutes to sunset, 42 minutes left in this TDRS-West pass, this EVA is finishing up.
Richard
-
Danny starts his trek back.
Just 6 mins margin! Afterwards they would have had to go regardless.

I think the radiator gets retracted on STS-120 just before the P6 is moved to outboard of the P3/P4 truss on that mission.

What a difference a day makes. Yesterday, three down computers, solar array in limbo-land, Shuttle OMS pod damaged. Today, two computers up, solar array retracted, Shuttle OMS pod repaired. It's been a good day.
-
Silver lining here...... is it safe to say this is the last big U.S. solar array they'll ever have to do?
Iknow the FGB has a retraction coming and certainly P6 will have to be redeployed....
-
It has been a great day for the shuttle and station, and I am really going to miss the shuttle when it is retired, it's a great vehicle that allows repair tasks like this.

They may have to retract one of these extended arrays if the transformer type of device called a sequential shunt unit (located at the top of the arrays) fails and needs to be replaced. The SSU can only be replaced when the arrays are folded in and not producing power. Hope that never needs to be done.

Here is the last update for me for the evening as this EVA wraps up successfully, we are in a KU pass with TDRS-West for about the next 28 minutes, to be followed by a comm pass with TDRS-East, then the ZOE in 64 minutes. Sunset will occur in 30 minutes and we are just starting orbit 113 as we pass over the equator. Thank you every one for your comments and updates, have a good night, and we will do this again for EVA 4 on Sunday. See you all later everyone.

Richard.. great job with the KU coverage.. many thanks.. never really could understand what was noted on the FD exec packages

It is unfortunate to have to keep multiple windows or tabs open just to follow a single live event. However, this is a great site and if Chris says we can only post while standing on our heads and singing our favorite country music song I will happily comply.

It's not that people talked about the two interchangeably - but their "this is what I think" or "what does this mean" posts REALLY crowded things in a hurry. So if you were interested in the EVA, filtering through a dozen "what is a lane?" questions makes it MUCH more difficult. If this thread strictly was a report on the happenings I think it could have stayed here.
But we all know that doesn't happen on a public forum without kicking a lot of people offline.
