Summary timeline for today's EVA3 tasks.
This is taken from the EVA Flight Data File so if it is updated in today's execute package (not posted yet as I type) I will replace the graphic.

Wake up music "Hotel Cepollina" by "Fuzzbox Pirana" for John Grunsfeld.
Oddly enough, I can't locate a link to this song :)

STS-125 - EVA 3 Overview

From Execute package p-14
HST Program Words:
Once again, your extraordinary effort has strengthened the Observatory for its continuing
mission. All the gyros passed aliveness and functional testing, and Hubble is once again running
with a full complement. The Battery Module also passed its aliveness and functional testing.
Analysis of the WFC3 performance tests were completed, and show some excellent results. The
noise on the UVIS channel is 3 e-, and the IR channel is 6 e- for the readout only. All
thermoelectric coolers were tested and appropriately draw current and exhibit cooling. WFC3 is
now safed awaiting SMOV operations.
-
Crew called down with answers to the EVA questions in MSG 039A from the execute package about 30 minutes ago...
-
I have a question regarded to today tools which will be in use. Hope you guys can confirm it.
So first attachment - this manual tool will be use to unscrew 32 fasteners (on cover plate), yes? I dont also get correctly how is working this fastener capture plate, could someone explain me that? I heard that the point is to avoid breakin fasteners (need confirmation/explanation).
Second attachment - is that "wishbone" tool which will help to install CET (Card Extraction Tool)?
-
G2 Set expansion in work at this time. Dual G2 with GPCs 1 & 2 like this
String 1 - GPC 1
String 2 - GPC 2
String 3 - GPC 1
String 4 - GPC 2

The first tool is an FET (Fastener Extraction Tool) and is basically just a manual screwdriver (there are 14-inch and 9-inch versions, the smaller one a "mini-FET").
The second tool is actually the business end of the Mini Power Tool (MPT) which is a new tool and is a more delicate version of a Pistol Grip Tool (PGT). It has a battery pack at the end of a short umbilical cable.
I've attached a 3-D graphic of the hand-held part of this tool.
Not sure of the intricate details of how the screws are held by the fastener capture plate at the moment :)
-
Leak check complete; EMU purge coming up.
-
MikeMi - here are drawings of the "wishbone" which holds the card extraction tool in place during circuit card removal from the ACS.
-
EMU prebreathe started
-
Thanks Analog! Really pleased to see all these schemes. I like to know which tool is use for and so.. appreciate it ;)
These cards werent build with thought to get them from it' container, no?
This "wishbone" is amazing thingie.. :)
-
EMU prebreathe started
Started at MET 18:33 (or about 35 minutes after the hour) for about 40 minutes. That leads to airlock depress.
Preparing for HST rotation.
-
Nice sunrise
-
About how long should it take to take out a screw on the
ACS and STIS?
-
-
HST rotation to -V2 side forward underway.
-
Interesting reflection in the first image.
Rotation...

Had to do a little troubleshooting with display on John's suit - all OK now.
Continuing with depress cue card before beginning EVA timeline tasks.
-
Some of the lights and shadows you can see over the thermal hatch make it appear like they are underwater!
Morning/Afternoon everyone, that's my contribution so far, you're welcome ;)

If anyone is wondering what this "MFR Handle" is that the EVAers are handing off between each other, this is what it should look like for this EVA (photo taken during NBL training).
It carries lots of tools/tethers/aids required by Drew whilst on the SRMS (it fits to the MFR)

"do that again Drew"...someone was taking picture inside! :)
-
One of the large internal blankets has peeled off of aft shroud - entire +V3 side

John setting his PGT as needed for the alignment aid deployment lock.
-
COS install should take about 45 min
-
Please forgive me if this is not the place for a basic question: I'm curious why the decision was made to perform such an elaborate and risky repair of the ACS instead of replacing it?
Was there simply not enough time to build a new instrument? Expense? Payload constraints?
-

KU is back
Drew about 6 feet from telescope
-
"Beautiful instrument"
-
Lost KU again
-
Drew will guide the COS in until he sees 'B Ready' lights.....once he gets that he will maintain slight downward pressure on the instrument.
John will then move in to start on the B Latch.

Nice article Chris.
-
Bit of vertical motion observed. Reseating on the 'B Latch' plunger and retrying.
-
having a slight issue at the moment. Only 2.1 turns, but expecting 5 turns.
-
Going now....11-1/4 turns
-
B latch complete - now A latch
-
Good torque.
A seated.
B latch done
Excellent.
-
The thinking was that there shouldn't have been any movement of the COS during the turns. Some motion was observed but after 2 turns which MCC advised was okay.
-
Expecting 11.5 - 15.5 turns for A latch
-
A latch 14 turns - lights off.
-
Torqued out 14 turns.

Ground strap attachment will be worked by John in a moment.
Followed by inspect and mate of the COS connectors as shown:
-
"turn me to my left....my other left"...lol
-
Ground strap done.
Ready for 4 connectors

All connectors mated
-
P3 mated

Aliveness tests in work on COS
-
Ground wants to confirm if a handle is loose based on helmet cam images. Concern about a wing nut being loose that would cause this.
-
Confirmed: handle good.
-
John is go to pad the thermal blanket back into place.
No joy
Pressing on.
-
Some serious hardware in there.

Current EVA-2 Duration 2hrs 30 minutes. Flying over KSC!
-
Groundstrap bag tethered to handrail
-
Seems ahead of the timeline right now, but how much?
-
Small FOD liberated out of the telescope.
-
Bag in now tethered to the handrail clamp. Nothing can float away
Small bit of FOD departed the ground strap bag and departed the space telescope. "good"
-
They seem to be bang on the timeline at the moment - should be starting the COSTAR installation at 2:40 PET which is what I currently make it.
-
Smaller patch of moisture still on the camera ? 1" wide and 1-1/2" high
oval in shape.

yup. I couldn't make out the first size reference btw (?)..should have been after 'wide'

"looks really amazing actually"
ain't that the truth :)

Anyone got a mass figure for COSTAR?
-
Has to be noted, but great work by Megan on Robotics again.
COS working fine!
-
Good aliveness test on COS
-
COSTAR's home for the ride back to Earth:
-
COSTAR going in the box
-
COSTAR being guided into the ORUC.
-
-
Looks like COSTAR is secure.
-
Anyone got a mass figure for COSTAR?
299 kg
-
"It's a really tight fit"
-
Tight fit!
Time for the latches.

In transition to the next latch/bolt.
-
Elapsed time 3 hours
-
COSTAR all but stowed.
-
John working on ground strap bolt - want 15.5 turns
-
Drew moving to next work site - ground strap bolt?
-
A little twist and turn on the base of the MFR and you're facing in the other other direction :)
-
Wiggle test on the stowed COSTAR
-
Not as tight as he would like it. They are going to give it a bit more torque via the PGT.
-
In work
-
That's done the job on the grounding strap.

Hubble Jeopardy
By Dennis Overbye;
Published: Sunday, November 28, 1993
One screw in particular.... Known as the "A" latch, it's not just any screw; this one is a rod seven feet long. It holds the $100 million WFPC camera, about the shape and mass of a grand piano, in place on Hubble. There's a light to tell when the latch is about to settle in, and there are springs to keep it from jamming too far.
-
Go to close the protective covers.
-
John is a go for ACS repair prep.
-
Meanwhile, Mass is a go for ESM P11 turnaround.
-
Back into orbital nighttime.
-
" this is much easier than moving around in the pool..." :)
-
11:46pm Central time is the mark PAO Kyle is giving to the completion of COSTAR stowage in the ORUC.
-
IV swap
-
Mass praising the work conducted on the COS/COSTAR. IV changeover on Atlantis.

Megan did a great job...they all did :)
-
Waiting for ACS deactivation/power down.
-
ACS prep work is starting on time - due PET 3:20 about 3:16 now. Drew already started John just finishing up PFR set-up
-
Kyle preempting just how bloody difficult the ACS repair will be, as it was not designed to be repaired in space.
Articulating foot restraint being worked.
-
First 5 of the STS-125 priorities now completed. (The list is the first thing I could find via the SSP FRR, it's refined since then).

-
I have to run guys. Thanks for the postings & images.
Have fun out there John & Drew! Will follow later today :)
-
-
Bay 3 on priority 5 not done yet is it?
10 done too.
Why is it STIS or ACS?
-
-
Ku back in five minutes.
-
Blue debris coming out with screws.
Sounds like screws are also longer than expected.
-
Hadn't noticed a change for a while over recent days, but noticing Atlantis is changing her attitude. Water dump or normal thermal requirement?
-
KU back
-
Ku coming back.
-
Three screws out, one to go
-
All four screws removed.
-
All 4 screws out
-
Why is it STIS or ACS?
From one of the press conferences the other day, they want at least one instrument upgraded. If there's a problem that one can't be worked on, then the other one pops up in priority.

-
There are a total of twelve bolts to drive.
-
John has just installed some guide pins in the places where he removed the four screws a little while ago. These guide pins will locate the Fastener Capture Plate - and possibly the grid cutter tool that he is currently using.
Guide pin drawing below.
Edit: Note that the knurled knob and tether attachment are released once the stud is installed.

Guide pin drawing below.
-
There is a grid over the CCD electronics box (CEB) cover. This has to be cut away using the grid cutter tool, before it can be removed. The grid cutter tool actually cuts the grid away and provides the EVA team with a safe way to transfer the sharp grid into a storage bag.
-
Special pin removing thingy (I have no idea what it's called) being used.
Thats the FET (Fastener Extraction Tool) if I recall correctly :)
-
And that's complete.
-
Grid is off
-
Initial trouble removing the grid cutter. John has managed to persuade it to come off.
-
Are those white horizontal signals in the TV image some sort of telemetry? Shouldn't they be in the vertical blanking interval, or are the meant to be in some random place in the visible TV field like that?
-
The next step is to install the Fastner Capture Plate.
-
Glove checks OK
-
fastener capture plate next
-
Torque will be broken on the 32 CEB cover fasteners before installation of the FCP.
On 7-78 of the checklist.

-
It really sounds like this EVA is going as smooth as can be hope. Are they ahead of the timeline, if so can they do Part 2 of the ACS repair today?
-
FET going to be used to release fasteners, 1,2,3,5,11 and 32.
-
Removing electronics box
-
I'd estimate things are pretty much on-timeline.
-
Fasterns coming out..
-
Removal of the CEB cover will allow access and removal of the cards within.
-
Go for ACS repair (has been powered down).
-
Crew is go for ACS repair once they gain access
-
"I don't think brain surgeons go woo-hoo when they pull something out."
"Well, they should!" :D
-
The FCP clamps to the panel they are going to remove, but it leaves space for the 32 (?) screws to back out. The screw heads are accessed through holes that are too small for the screws to pass through.
The sticky pads hold the panel in the middle of the FCP area, whilst mechanical latches grip the outside of the panel.
The combined FCP and panel will come away as one unit with the screws trapped between.
-
Mini power tool being used to access the 32 small screws - specially designed for this task.
-
"you are clear to remove the remaining 27 fasteners"
...I don't think we will hear a command like that very often!
-
Out comes the Mini Power Tool. The MPT is being used to remove the remaining fasteners (yes, there are 32).
Also there is no need to provide a means for replacing the 32 fasteners as a replacement cover is available. However this replacement cover will not be needed if install of the CEB-R (CEB Replacement) goes well.
-
And now for one of the neatest tools - the mini power tool :)
-
"you are clear to remove the remaining 27 fasteners"
...I don't think we will hear a command like that very often!
My wife would say "well maybe if you spent less time on that stupid website"!
-
suspense - do they have a procedure for stripped screws?
-
"I heard that all screw are out"
"That's true... but I am inspecting"
-
24, 25, 26, 27, 28
"I feel like a countdown timer, our countup." - John.
All out, but number 22 "didn't look all that great" - "Ok, 22 out."

Nice catch! There's quite a bit of banter going on. Helps relieve tension I guess!
-
Thanks a million for this coverage guys! :)
-
On page 7-79 of the checklist. Step 12 on the FF EV column.
-
Why have they cut away from the action inside? That's really disappointing :(

Looks like they are about 20 mins ahead of time.
-
Nice shot of the 4 cards
-
2 fasteners holding each card (top and bottom)
Bottom fasteners released on all - working on the top now
-
...so far ...SO good!
-
All fasteners released on all cards

Yeah, that was from Deep Space Homer. Not a word for word quote, but close enough that you knew the intent.
A quick search turned up this from the script:
Tom: It's a lovely day for a launch, here, live at Cape Canaveral, at
the lower end of the Florida Peninsula, and the purpose of
today's mission is truly, really electrifying.
Man 2: That's correct, Tom. The lion's share of this flight will be
devoted to the study of the effects of weightlessness on tiny
screws.
Tom: Unbelievable, and just imagine the logistics of weightlessness.
And of course, this could have literally millions of applications
here on Earth -- everything from watchmaking to watch repair.

Yeah, that was from Deep Space Homer. Not a word for word quote, but close enough that you knew the intent.
A quick search turned up this from the script:
Tom: It's a lovely day for a launch, here, live at Cape Canaveral, at
the lower end of the Florida Peninsula, and the purpose of
today's mission is truly, really electrifying.
Man 2: That's correct, Tom. The lion's share of this flight will be
devoted to the study of the effects of weightlessness on tiny
screws.
Tom: Unbelievable, and just imagine the logistics of weightlessness.
And of course, this could have literally millions of applications
here on Earth -- everything from watchmaking to watch repair.
Thanks! Pretty sure it was an intentional homage.

I think they will also close the -V2 shroud doors after this cleanup, but that is only a 15 min timetabled task.

Once they've got the -V2 doors closed, I was wondering if they'd consider that...
Looking again, one problem with the NOBLs is that they are on the other side of the telescope (+V2 instead of -V2). Not sure there's time to rotate the telescope around.
-

Once they've got the -V2 doors closed, I was wondering if they'd consider that...
Original timeline was to finish closing -V2 doors at 5:50 PET, we're at 5:30 now, so unless they extend the EVA they probably won't have time to do anything else.

The functional test will take around 2 hours, and was originally scheduled to happen a couple of hours after the end of the EVA, but there may be such joy at getting the repair done that the ground pushes that forward ;)

Wow. Absolutely fantastic! This mission has never not amazed me at its complexity and successfulness thus far! Way to go John and Mike "Bueno" on a successful EVA-3 and the completion of the ACS repair! Every time I read about the possibility of completing the ACS repair I thought to myself, "Man, that would be nice. But with the way EVA's go... I don't know." I'm thrilled those thoughts were put to rest as "inaccurate" today.
Ok. Enough talking from me. On to to EVA-4/TPS DAT summary article I've got due in a few hours.

Checking their tool inventory.

Working in the shadow of the orbiter's cabin. Fantastic video.

"Nice work, congrats to you John and Drew and for the hard work from the folks on the ground." - Scooter.
-
The fix was only for one of three.
The Solar Blind Channel (SBC) was the only one working before SM4. They have replaced the electronics for the Wide Field Channel (WFC) and patched in a new external power supply.
There was not enough time to consider adding in repair of the High Resolution Channel (HRC) to SM4 but they think that this failed because of the internal power supply fault. The hope is that the HRC electronics will be back powered from the external power supply via the new WFC electronics. However, this is far from guaranteed.
So they hope they will get 3 good channels, but might end up with only 2, depending on how the old HRC electronics are.

I think I forgot to copy this into a flight day thread, but the personal walkout and launch videos from Monday are up on L2.

Preston was right yesterday with promising us non-problematic EVA ;)
Do I heard correctly - EVA ended with duration 6 hours and 29 minutes?

Ahh Ya - thanks for correction. Well it seems that it will be short MSB.

John says thanks to everyone who made the tools, and that it helped. Apparently has a friend who made one of the tools.
Followed by: "EV2 I'm just happy to be here" :)
EVA-3 concludes after 6 hours, 36 minutes.
Awesome EVA! Couldn't of gone better!
Thanks to everyone that joined in/helped with the coverage, especially Kel.
-
The replaceable things (WFPC-2 and RSU) were making much more trouble than the "nonserviceable" ACS. Let us hope this trend continues with STIS tomorrow. :)

-

Maybe. The ACS Functional is still pending, but there may be a bit of reaction to how impressively the repair came off and how smoothly the COSTAR removal/COS install went. And Dr. Leckrone may be asked about "calling the shot" yesterday.
-
any words about the time of the MSB yet?

Maybe an hour? Orbit 1 just finished, and they probably aren't keen to go running for the press room right away.
-
25 minutes from now. Someone is welcome to transcribe. Much prefer the MMT angle, rather than Hubble hugging ;)
-
I prefer the MMT angle too, but those briefings are way too late on this mission for viewing here in Finland (UTC+3).
-
Based on the pattern we've seen for the last several missions, I don't think we're going to see Leroy Cain (the MMT chair) on NASA TV again until the day after late inspections.
-

I can do that, been busy the last few days and could only read what you guys posted, so time to contribute a bit :) Invaluable coverage, not even a detail missed, thank you all for your dedication!
-
Thanks much :)
-
MSB starting.
-
All the big heads present, as yesterday.
Cecacci: Today's EVA more like expected, thanking all the teams. Great day, and having high confidence in tomorrow's STIS repair.
Crew happy (obviously), no changes to tomorrow's EVA, with STIS and NOBL.
-
González-Torres: 6h 36m total EVA duration. Reminding the 111 fasteners in STIS. No issues in COSTAR/COS swapout, really fast crew, they kept getting ahead on the timeline.
-
This man (whose name I forgot, sorry :) ) talking about COS, after remarking how smooth the day was. Citing the whole team, highlighting the adversities they had to overcome before, during and after the mission's cancellation. No doubt they'll be celebrating today.
-
Preston remembering how much they suffered these last days, with the glitches and hiccups in EVA-1 and 2. Grunsfeld and Feustel made it look easy today. 60% through SM-4. Only major task they need to accomplish is the replacement of the battery module that remains.
NASA manager who developed the amazingly wide set of tools for this mission's EVAs is among the audience in the press conference room, available for questions.
-
Lackrone remembering their paleness yesterday and on Thursday :) Adversity made the work to get done through extraordinary effort, today wasn't as necessary.
100% success so far. Very first internal repair of scientific instrument been demonstrated today. ACS confirmed to be alive, and over the next few days will be assessing its regained capabilities.
Ed Cheng is the mastermind of the ACS repair mission, and was also for the NICMOS cooling system upgrade in SM-3B.
Much more powerful observatory to observe the Universe available now. Looking forward to the operation of the two new spectrometers.
-
Harwood asking about how much capability they can regain in ACS depending on the status of the electronics in it.
The LVPS bypasses power to both side 1 and 2. The electronics on the CCD box (the ones that took the place of the replaced boards) will show their value when the functional test is complete, in the next few hours/days. They chose the Wide Field Channel, because it was the most used, but perhaps the High Resolution Channel will be repaired too, as we know.
-
Q: What was going through your mind when everything went like clockwork?
A: Everyone glued to their seats, didn't want to stop watching the repairs. Superb job by the astros, exhaustive training really paid off. Replacement electronic box for the CCD box developed under an extremely compressed timeline, lots of pressure on the developers.
Borrowed some of the equipment that had been developed for STIS, as that had failed earlier.
-
Note on the ACS Functional timing from the briefing...supposed to start at 6 pm Central (2300 GMT) and last for about four hours.
-
Av Week: WRT the robotic mission that never was, the capture plate had some heritage from it?
A: Dextre-related robot was envisioned, with special tools for very difficult and specialized activities. A lot of pioneering work was done during those years. Also wanted to robotically repair STIS when it failed, capture plate was one of the technologies developed for that approach. It survived the transition back to Shuttle-based repair. Working prototype was done on record time.
Even thought about combining the robot with the astronauts, letting them leave the robot overnight so that it did the job. Found it to be quite cumbersome, so dropped the idea.
-
COS avoids wasting light inside the instrument (minimum number of reflections) Versatile design, thought towards looking at distant quasars and measure the light that passes through the intergallactic medium to characterize the medium.
It has two-dimensional light detectors, what it basically does is get the light that passes through a slit and divide it into its constituent wavelenghts. Restricted to UV, coarser details than STIS, but broader spectrum. Few things in astrophysics you cannot do with both instruments.
-
Q: Highlights for tomorrow's spacewalk.
A: Apart from the 111 screws, the repair is more straightforward than in the ACS, because the board is right underneath the side panel, once you open it. Panel with a pair of levers so that it's easier to put back in place. Best time for removing the 111 screws is 40 minutes... comparing it with NASCAR :)
The 32 screws seen today went really smoothly, so the concept works.
-
Space.com: Do you have the feeling that the mission has passed a corner, after the challenging EVA-1 and 2, and the smooth 3?
A: The team needs to stay focused, because all this is very tricky. Enjoying the moment, but with an eye on tomorrow.
-
Q: What does the ACS expedite repair do to the priorities/timelines/extra time available? Any extra tasks?
A: "You plan your flight and then you fly your plan"
STIS will take pretty much the whole day. Although it's lower priority, they won't try to push the battery replacements or other EVA-5 tasks forward just because they may have the time. NOBL 7 may be installed if there is enough time available, already in orbit and ready to install if everybody is comfortable.
A: SIC&DH prompted the battery bay changeout deferral to EVA-5 to give more margin to the astronauts. Thanks to things going really well today they can think about finishing both ACS and STIS.
-
-
Q: One out of two repairs was considered success... how is this being looked at now?
A: They didn't go into the trouble of developing both repairs just to drop them once one is complete. Both instruments are equally important, the community is hungry for these instruments, so difficult decision which to put forward.
If there was any problem with the orbiter or something, batteries and FGS would have higher priority, but that's the only circumstance under which they wouldn't consider trying to repair it.
-
Q: Asking for another prognosis for tomorrow's EVA by Lackrone ;)
A: Mass and Bueno are very competitive, so tomorrow's gonna be really smooth too, because they could do their tasks sleepwalking (so better spacewalking, obviously!)
-
Q: What is the biggest item in having confidence in tomorrow's EVA success?
A: The capture plate: after seeing how well it worked, the confidence has risen a lot.

MSB over with a lengthy programming 'note' by Navias, as per usual :)
-
Thanks David, good work :)
-
No problem, a pleasure to contribute :)
Did anyone catch what was that "soaked towels" conversation about? Were they referring to how much they sweated during the EVA?
-
I missed the "soaked towels" but caught the "it ain't ready 'till the fat lady sings".
Dr. Lackrone was like floating in his chair. Always nice to watch an exuberant, happy man, especially if he's an astrophysicist in a manned space flight context ;)
Go NASA !
-
Did anyone catch what was that "soaked towels" conversation about? Were they referring to how much they sweated during the EVA?
There was a fistsize ball of water clinging to some filter on (I think) the middeck. They cleaned it up with three towels.
-
Thanks for the answer, it was the humidity reclamation system under the middeck floor that was developing the water accumulation, according to the commentary I just heard. Somehow it didn't seem natural that they sweated so much as to drench a pair of towels... sort of reminded me of Leonov :)
Agreed about Lackrone, he's great during the briefings, in contrast with some of the other participants, who just appear to mechanically throw together the same expressions and phrases to suit the situation. Probably very proffessional and capable people, but the message gets lost in the NASAese...
Great day, looking forward to more non-stop Hubble fun tomorrow.
