And the FD5 Execute Package is up:

"WFC3 completed its aliveness test but we had a minor issue during the functional test.
There was a glitch on an unused, but limit checked, digital to analog output line that caused WFC3 to suspend. Testing has resumed and is going well, should have some good news during post sleep."
-
Over Sahara - amazing view :
-
Morning ;) Not a bad wake up song. Haven't heard it before, but it's a foot tapper.
EVA-2 scheduled to start in two hours.
-
Not a bad wake up song.
I guess they heard you complaining yesterday and now they're trying to please you! ;)
-
Comment from the ground saying that there was a good functional test of WFC3.
Good news.

They've got a way to go yet.

good morning... off to work soon but hoping for the same great level of coverage in todays spacewalk..
-
SRMS inspection of port TPS (missed by FD2 Inspection) picking up. 45 minute job for the EE.
-
Arm moving - getting set up for the survey of the last batch of tiles
-
-
-
-
Well they aren't lacking lighting! Asking for the Iris to be altered to counter the glare.
-
-
You can see one of those putty repairs in the top left.
-
-
-
One of the tiles has a bit of a ding it would seem (possibly).
-
ok... off to work (dammit!!) fingers crossed for a smooth spacewalk... keep up the good coverage - this procedure now complete
-
Pretty sure the below is a good example of a putty repair:

Thanks for the help. Tell them I said you could have the day off, they'll be cool ;)
-
SRMS viewpoint from upon high. Heading over the middle east according to Kyle.
-
Nice view. Second image you can see the Nile.
-
It's very cool seeing the waters I've sailed from 350 miles up!
-

Nice! And a good point, as there's a lot of our brave lads down in some of these views of the Gulf region.
-
Out of Ku. EVA in purge, ahead of pre-breath.
About one hour from EVA-2 (slightly delayed).
Off to get some food, if someone could keep an eye on things.....thanks.
-
John reports start of pre-breath clock: 17:49
-
Question about Flight Day 3. During rendezvous they had trouble with the BSA (Bit Sync Assembly) which prevented them from getting command confirmation back from Hubble, and so they had to rely on the TDRS-to-ground link and verbal uplink to shuttle to confirm all commands. During a later press briefing Tony said they'd resolved that problem and it would not be a problem during deploy. I believe he said that the wrong bitrate (1 Mbps?) was configured on Hubble. Do I have that right? I found nothing about it in the FD3 thread or L2. L2 has nice BSA background info though :)
-
A quick question about yesterday's EVA.
Was the torque limiter set to 45 inch/lbs or 45 ft./lbs?

pre-breath is currently taking place.. and I was wonderin if Massimino and Good are separated from crew onboard Atlantis? Are they locked in airlock during this procedure (its enter my mind when was askin myself if they getting oxygen from shuttle stores or from EMUs)?
Thanks for answer.
-

Yes, they closed the inner hatch a little while back. They will step into depress of the airlock now, as the pre-breathe clock has finished.
(Whether the suits can still get "consumables" from the orbiter isn't directly related to isolating the airlock from the rest of the crew module.)
-
go for depressurizing the airlock
-
What's with all the noise?
Will we have to put up with that for the entire EVA?
-
Hatch open, thermal cover blown open.
ETA: Now on battery.
-
What's with all the noise?
Will we have to put up with that for the entire EVA?
It's like that on every single EVA.

That sounds like you might of gotten some interference on the feed, as it's still the same for me :) That'd explain it, as it must of sounded like something unique.

What was that call about the Flash Evap?

7:49am Central start time for EVA-2

From the Execute Package Re: Canon Photography feedback: "Interior shooting - watch getting only the backside of people"
Is this going to be a note re future mission coverage? It always makes me smile how so much of manned spaceflight is similar to a camping trip, all those bodies sharing the same small space. And all past mission coverage I've seen where you can't tell who you're watching because you can't identify individual astronauts by their socks or their arse :D

Comm checklist being worked, as there's an issue with Mass' comms to the crew on the flight deck - and that's corrected.
"That was scary! A little bit" :)

Garbled, but Mass said it was the next thing he had to do on his list, so might of missed a step.
-
A quick question about yesterday's EVA.
Was the torque limiter set to 45 inch/lbs or 45 ft./lbs?
They were saying 45 ft./lbs
-
Good egressing the airlock.
"Welcome to the wonderful world of working in a vacuum" Mass to Good.
Good idea how big her payload bay is via this:
-
-
-
Thermal Cover on the airlock is closed.
-
-
-
MFR installed.
Good taking some time for a quick adaptation of being on an EVA (given it's his first) - per Kyle.
-
Good on the MFR. Megan translating him to the ORU:
-
-
-
-
Mass with the SOAP.
MCC-H calling Scooter over the FES. Notes of "it could have been an ice issue, but in a good config."
Problem with Pri A on the FES. Requesting FES Pri B to off. Heater duct select A/B.
Core flush possible post EVA, due to the signature of ice on Pri A - causing it to shut down.
(two loops overlapping, so if anyone catched more, add to the thread).
-
-
-
-
Call to watch out for lube on the bolts.
Doors to the Fixed Head star tracker about to be opened.
-
-
-
-
RSU changeout is go, after safing commands have been confirmed.
-
-
Out of Ku, heading into orbital night.
-
Go for RSU connector demate.
-
Ku back in 20 minutes. Flight Day 5 MMT presentations are in, so back after uploading them to L2. Although I'll try and multitask (wonders will never cease :D)
-
Aft shroud doors being opened. Nine minutes to Ku.
-
Bueno has released latch bolts (3) of FHST (Fixed Head Star Tracker) doors
Handle bolt left to do before can open the doors
-
Handle bolt released (on second attempt to engage)
-
PIP pin released from handle latch, handle rotated and PIP pin re-stowed (slight difficulty with that).
Doors can now be opened.
-
Both doors open, one hour into EVA-1. Ku back shortly - or now:
-
-
Glove check. A bit of yellow observed on Mass' gloves, but no damage.
-
One of the doors wants to spring closed, asking if they can use a tether to restrain it.
MCC-H agree, saying they don't want it hitting the radiator.
-
-
-
-
Door being tethered open. Causing a bit of a delay. Patchy Ku.
-
Tether securing a success.
-
-
And Mass has gained access to inside of Hubble.
Has noted a "funny looking connector."
-
Mass enters the aft of Hubble. Good holding his legs!
-
Mass is seeing what he expected to see (as per training).
Go to demate RSU connectors, P1 and P2 demated.
-
"Story wuz here"
-
Mass helmetcam looking at Good from INSIDE Hubble!
-
GoodCam removing the first of three bolts. You can see Mass tucked up inside Hubble.
-
Bolt removal going well.
-
First RSU is out.

New RSU installed. Only required two bolts.
Mass mating electrical connections.

Here's the RSU task overview via the Flight Plan Walkthrough Presentation:
RSU R&R: The RSU changeout procedure is the same for each RSU. IV rotates the
BAPS to the RSU changeout position. The Fixed Head Star Tracker (FHST) shutters
are verified closed from the standard switch panel and the RSU is deactivated. The
ground handles most of the RSU commands. EV3 is going to use a PFR, so he
retrieves it from the Axial Scientific Instrument Protection Enclosure (ASIPE). EV3
and EV4 head over to the SMALL ORU Protective Enclosure (SOPE) on the ORUC
where the RSU’s are stowed, retrieve RSU-2, and transport it (in a thermally
protective bag) to the –V3 aft shroud. While EV4 is holding the door handles, the
RMS backsaway to open the doors. They then begin performing the RSU-2 R&R.
EV3 disconnects RSU power connectors, while EV4 disengages three captive bolts.
EV3 removes the old RSU-2 and hands it off to EV4 who temp stows it on the top of
MFR handle. EV4 then seats the new RSU (RSU-2R) and engages the bolts, while
EV3 mates the connectors. HST performs an aliveness test. The EV crew return to
the SOPE to stow the old RSU-2 and retrieve the new RSU-3. The R&R procedure
is then repeated for RSU-3 and then RSU-1. After all three RSU’s are replaced, the
–V3 doors are closed. Sun protect attitudes are no longer required at this point. EV3
returns his PFR to the ASIPE.
-
9:40am Central, mating of the connectors marks the full installation of the new RSU. Will be tested very shortly - in fact the liveness test is going to be conducted right now according to Kyle.
-
RSU 2 installation to be followed by RSU 3 installation.
Atlantis on her 60th orbit of the planet on 125.
-
Good helping Mass out of the telescope.
-
Are they running ahead of the timeline?
-
Good's been shopping, picked up an old RSU and a spacewalker.
-
Good liveness test on the new RSU 2 and go for RSU 3. Good taking Mass to the SOAP.
-
can't do too much... but will add as I have time
-
Great image.
-
-
Are they running ahead of the timeline?
They were a bit behind with the door that wanted to spring shut, but the first RSU changeout went well.
Kyle's not mentioned if they are on the timeline yet.
-
Some real nice pictures on this spacewalk...
-
At the SOAP, stowing the old RSU for it's ride home, will be picking up the next RSU (RSU 3) for installation.
-
I have video running at work but no sound.. I can only post pictures so others will hopefully fill in the commentary...
-
-
Next RSU gathered. Will be a repeat of the previous RSU - to be located in the upper left of the aft shroud.
-
-
-
Getting into the foot restraint
-
Mass, Roll Program (people without audio won't get that)
-
Go to demate RSU3 connectors. P1 out. P2 out.
-
-
2hrs:15mins into EVA-2.
-
-
Top bolt, 11 turns, spring loaded, on RSU3 unmate task.
-
-
Bolts coming out easily. PSU is a bit stickier coming off the plate, however.
-
-
its free!!
-
Over a 1/3 through EVA-2. Out of Ku for 18 minutes.
-
Waiting for the bolts to be torqued on the currently being installed RSU3, ahead of the connectors being mated and the liveness test.
-
current positions
-
RSU3 appears to be a bit more troublesome with the bolts.
-
and we are back -
-
RSU3 appears to be a bit more troublesome with the bolts.
Correction, they still haven't got to the bolts yet, still trying to seat RSU3.
-
video seems ratty right now...jumping in and out
-
MCC-H discussing the problem with installing RSU3 on to the plate. Really isn't happening for them at the moment.
-
"This one feels like it won't fit flush on the plate, feels like it's rocking." Mass.
"Could it be possible the soft dock velco might of come off the old one, so you might have extra layers of velco obstructing." - MCC-H.
-
"This one feels like it won't fit flush on the plate, feels like it's rocking." Mass.
"Could it be possible the soft dock velco might of come off the old one, so you might have extra layers of velco obstructing." - MCC-H.
Mass says it's only one layer visible (so that isn't the problem).
-
Really trying to bolt that on....
-
Still no joy.
"Oh boy."
"Feels like there's a bump underneath it."
-
-
"It's like it's bumping up on something. Those guides are the problem."
-
-
-
Nice leadership from Scooter, who can tell they are getting annoyed over this.
"You guys are doing a great job out there and (something about keeping focused)".
-
Yeah, something about "managing your frustration".
-
Looks like they are going to use part of the RSU2 changeout guide/tool (can't catch exactly what) on RSU3.
-
-
Looks like they took off the PIK STIK seating tool aid, and seated the RSU by hand
Doing up bolts now
-
Damn, that didn't work either - Mass. Says it popped loose, but still putting bolts in.
Pending.
-
No, didn't work. Asking for a plan. They might try RSU1 in RSU3's position.
-
-
MCC-H concur with trying the new RSU1 in RSU3.
-
However, Mass wants to try it one more time.
-
Mass really wants to try it one more time, but is being overruled.
-
Big picture:
RSU3 in the thermal bag.
Take out center RSU (RSU1) and try and install it in RSU3's position.
-
-
Good not confident this is going to work. MCC-H want a good look at the female end of RSU3 to check for the interference.
Remember, this is priority one for this mission, so not a great situation right now.
-
comparing ??
-
Found this in the EVA checklist from L2. Chris hope you don't mind this being posted.
-
For reference this is a picture of the PIK STIK tool they have been using to handle the RSUs during seating.
-
back in the bag
-
Mass thought they really had an alignment that time. Grunsfeld praising them for their efforts.
"Just doesn't want to go."
-
Found this in the EVA checklist from L2. Chris hope you don't mind this being posted.
It's cool, please do (I think NASA released the bulk of that later anyway) but people can post FRR documentation as valid, free run to get any L2 resources into this thread for this issue.
-
Are they trying RSU1 in 3s position just for troubleshooting to see which part the problem is on? And if, as it often happens, 1 goes into 3s slot and 3 goes into 1s slot are they completely interchangable so they could leave them that way.
-

Good question, not clear. For some reason, Good or Mass said he doesn't think it'll work, but if RSU1 is good in RSU3's position, I can't see them taking it out again (but I'm guessing!)
-
"Might be the base plate."
-
-
Having a snooze in hubble.... hmmm.. Is there any such thing as "lying down on the job" in space?
-
Looking at the timeline, the original RSU-1 R&R task (final one of the three) was due to begin around 3:30 elapsed time - we are at about that time now.
-
Some talk of confidence that RSU1 will go into RSU3's position without a problem.
Adding content from the SSP FRR presentations on L2:
-
"We know two previous RSUs have been installed into here."
"I think we're gonna get it."
-
Here we go.
"Ok, let's do it!"
-
"Looks good?" "Looks good to me!"
-
Forgive my ignorance, but how critical to Hubble's mission are these 3 RSU's?
What are the ramifications, if God forbid, they can only get two of them installed?
-
"I think I got it."
"Woo hoos" heard all round.
-
-

Already mentioned on the thread and in the article, it's prority number 1 of 11. They have two of them installed now.
One more to go.
-

HST can operate on 2 of 6 gyroscopes (however, they prefer to use 3). Each of the three RSUs holds 2. However, they do fail so the more they have the longer they can go with operating units.
-
P2 then P1 to mate (electrical connectors).
-
"We're estatically able to announce successful installation of RSU".
-
Now if they could make RSU 1 fit in the space for 3 then all is golden.
-
Mass coming out of HST
-
-
I think they have the option of a spare in the COPE
edit: PAO says this is older design so not preferred option.
-
Now if they could make RSU 1 fit in the space for 3 then all is golden.
*Nods*
Wouldn't be a shuttle mission without some EVA excitement :)
Mass leaving his position in Hubble as they go back to the task in hand of R&Ring the final RSU. Hoping RSU3 will fit into RSU1's position. There is an old unit if that fails, but they would obviously prefer to successfully install the new RSU.
-
Glove checks
-
damn it looks like fun out there....
-
Go for RSU 1
-
MCC-H would prefer not to head to the COPE for the spare, they really want to get the new RSU in the alternate position.
-
Good aliveness test on RSU3!
-
Lovin this coverage guys. Fantastic work!
-
If this final RSU goes in, it'll be one hell of a turnaround.
Everyone think happy RSU thoughts :)
-
-
Nice shot of the RSU's
-
Happy RSU thoughts. Great coverage from everyone. Go RSU 1
-
-
From what the PAO said, and after some quick math, it sounds like they are about 30 minutes or so behind schedule.
-
-
Hello!!!!
-
-
Flying over Nairobi, Kenya
-
Glove check for Good, gloves are fine.
-
nice views these guys get...
-
Go for RSU 1 changeout.
Electrical connectors demated.
-
RSU1 changeout is go, starting with connectors P1 and P2 to demate.
-
fingers crossed!!
-
Bolts coming out. One out already.
-
Removing bolts
-
turning easily it appears
-
Three bolts removed. RSU is free.
-
RSU 1 is out!
-
and out she comes
-
RSU1 is out of Hubble. Over four hours into EVA-2.
-
A little over 4 hours into EVA - did we lose KU?
Edit: PAO reports television out until 20 minutes after the hour
-
A little over 4 hours into EVA - did we lose KU?
Yeah. Hope we get it back in time for the installation.
Thanks for the images (yourself and Stockman) too!!
-
MCC-H gave go ahead for PIE harness retrieval, this means they will do the 15min get-ahead task after RSUs (all being well)
-
Ready to install RSU 1
-
Still no Ku, but about to install the new RSU.
-
Feels wobbly - driving bottom right bolt
-
"Feels wobbly like the other one" Trying the bolts.
-
"No joy".
-
"Feels just like the last time, just does not want to be on there." Crap!!
-
Feels just like last one - doesn't want to seat.
Going to get spare...
-
Got kinda lost there. I didn't know if RSU 1 referred to the gyro or the slot sometimes.
I'm guessing they can use the magnetorquer for roll control of two gyro ops?
No worries. Battery changeout will go so smooth it'll make a baby's butt look like sandpaper.
-
Going for the backup plan of installing the less desirable spare.
-
Wondering if it is a manufacturing issue? Perhaps the bottom somehow got warpped?
-
No worries. Battery changeout will go so smooth it'll make a baby's butt look like sandpaper.
HAHAHA.
-
the lucky ones...
-
I know the engineers will want to see the balky RSU back on the ground, but I'm sure the spacewalkers would like to take a sledgehammer to it.
-
KU is back!
-
we're back early
-
-
Mass handing spare RSU to Good
-
About 1 hour behind schedule
-
Replacement of RSU 1 is priority #1
-
Something floated out of the bay just now...(the white dot in the two pictures below)
-
Spare unit (think I heard serial no. 1005) was removed on STS-103 (SM-3A). The new unit that wouldn't seat was I think serial no. 1007.
-

You heard correctly!
-
Something floated out of the bay just now...
I saw that, went out fast!
-
Going back in to HST
-
Why is the spare less desirable?
Is it that it is not a new build one but only a refurbished one?
Will it potentially have a shorter life?
-
Forgive my ignorance, but I even searched and checked the acronym list... what is the "COPE" container? what does it stand for?
-
Going for bottom right bolt - here we go!
-
So far so good with this RSU!
-

Refurbished
-
Any chance they'll take the problem child inside to get a better look and possibly fix the bent guide or remove Story's old piece of bubblegum or whatever? Or would entering an unblessed, pressurized non clean room environment disqualify it?
-
-
Spare RSU seating properly :)

-
4 hours 41 minutes into spacewalk #2
-
ok... lets hope this one fits..
-
This one appears to be stuggling too.
-
"I just can't get it on" (the plate)
"It's wobbling on the top pin. I'll try and drive the top bolt, but it hasn't worked yet."
-
trying to screw it on??
-
Driving the bolt worked! Trying the other bolts.
-
Bottom left bolt is in, bottom right in now too.
-
YEA!!
-
It's working out for them! (You could hear Megan with the "yaaaaa!" in the background).
-
checking connectors
-
P1 and P2 connectors to mate, and that'll be job done for the RSU! Excellent!
-
Connecting P1 & P2
-
and now the other side
-
Any chance they'll take the problem child inside to get a better look and possibly fix the bent guide or remove Story's old piece of bubblegum or whatever? Or would entering an unblessed, pressurized non clean room environment disqualify it?
I was wondering the same thing. Just to get a chance to see it without all of the EVA gear on might show something obvious.
-
Scooter "Remember this day men, as it will be yours for all time" :)
-
Well if the refurbished spare can continue to work for the next five years (along with the two new ones) then there's nothing to worry about.
-
Exiting the telescope
-
Will they still do the battery next?
-
more great views...
-
Will they still do the battery next?
PIE harness get-ahead install next while they have this bay open.
Its an electrical cable assembly (not sure what PIE stands for yet!)
EDIT: PAO PIE is Power Input Element
-
Going to ACS connector panel
-

The ground asked the crew where they wanted to put S/N 1007 (COPE or airlock), but I missed what they responded.
-
no clue what I am looking at here..
-
View from Mass helmet cam inside HST.
Currently demating and mating cables (sorry, I didn't catch which ones).
-
He's trying to connect the cable to ACS J1. Having some trouble since he has nothing to hold on to, and can't get any leverage to mate the connectors.
-
Mass is having a little trouble connecting cables. When he pushes on the connector, he is pushing his own body rather than getting the cables connected.
-
Finally got it!
-
PIE harness install complete.
Coming out of HST again.
-
-
back out - nice reflection
-
Closing shroud doors.
One and a half hours behind.
Going to battery replacement task.
-
-
Next up:
Bay 2 Battery R&R: EV3 retrieves the new Bay 2 Battery from the SLIC. On MCCGo,
EV4, at the Bay 2 location, removes the old battery. The two EV crew swap
batteries. EV4 installs the new battery, while EV3 translates over to the SLIC to stow
the old battery on the SLIC for return. The ground will perform an aliveness test
followed by a functional test.

Closing D3 shroud doors.
One and a half hours behind.
Going to battery replacement task.
It is -V3. +V3 is on the opposite side of the Aft Shroud. -V2/+V2 are on the axial sides of the Aft Shroud.

-
PET 2 hours. Still planning on changing battery (scheduled for 1.5 hours).
-
Sound's like they're going to extend the EVA via recharging Mass's O2 so they can do the battery replacement.
-
Mass will recharge oxygen in his suit to be able to complete EVA.
-
5 hours 47 minutes
-
I love this "let's stay out here and press on until we get this stuff done" attitude. It seems so unlike NASA. Talking about getting more O2 for the suit. Is this pushing the envelope or what? Incredible mission. Incredible crew. Incredible attitude.
-
Planning on moving sleep and tomorrow wake up timeline to the right by 1 hour since they are planning on another 2 hours for EVA
-
Good's internal battery power right on the edge to make another 2 hours.
-
These guys rock, lets hope Hubble is nicer to them in the next couple of hours!
-
Mass finished recharging O2 in his suit.
-
Beginning battery replacement - should take 90 minutes.
-
Scooter has turned the RMS duties back over to Megan.
Drew now working IV duties.
-
How many years have they been waiting for this. I am sure they won't mind a little overtime to get the job done that they have trained for. They would be disappointed if they didn't.
I know that when I see the pictures from Hubble in the future, I will have a different sense of the pictures having watched this repair live.
-
Moving on to the battery replacement task - here's a couple of pages from the EVA checklist reference section for orientation.

I had to do a double-take on that too (from reading). Definitely not used to hearing something like that on ISS, but this is most likely the last servicing mission, so they are willing to take the risk.
Great bunch these guys & gals.
-
Elapsed time over 6 hours

I suppose there isn't much need to push it on ISS since tasks that don't get done can be moved to a stage EVA if necessary. There won't be another trip to Hubble :(

Not particularly fair to earlier teams. This is exemplary, but I'm not surprised that the ground or the flight crew are willing to do this.

I just have to comment-
The more I watch these operations, the more I have flashbacks of being in a control room watching divers work a salvage job or well head underwater.
Of course, we never had video quite this clear due to silt and backscatter....
-
Old battery now demated - working on disengaging bolts holding it.
-
Good has removed first 9 of 14 bolts holding old battery on bay 2 door
-
Sheesh..I'm exhausted watching these guys..how many calories do they burn in an extended EVA like this ??...don't know how they do it...they haven't eaten anything in well over 7 hours...they've got to be starvin' by now....
-
Each is down to their last bolt.
Config shows Good at bay 2 door
-
If anyone is wondering where all these bolts are, here is a drawing of the battery with them identified (from the EVA checklist).
-
Both old and new batteries are free and clear.
-
One hour 50 minutes behind timeline - hope to make up some time during swap/install.
Elapsed time already 6:44
-
Should be ove southern USA now
-
Mass and Good haved swapped batteries - Good is beginning to install new battery at bay 2
-
I've gotta go back to work. Thanks to all for helping with the coverage!

FInal closeouts I assume..
-
Are all the tasks now complete for this EVA?
According to the Nominal Timeline, yes.
-
Are all the tasks now complete for this EVA?
Just the doors of bay 2 to fasten up, then clean-up and into the airlock
-
-
They made the decision to go for the battery work at 14:40 EDT, and it's now 16:10 EDT, so it looks like they nailed the 90 minute work time. During the discussion I'd heard a time estimate of "two hours" go up from capcom so I'm glad they beat that. Hopefully we'll get aliveness test results shortly.
-
Think 2 hours was with 30 mins getting back in etc.
-
There's a slight problem with one of the bolts. Losing count on the turns.
EDIT: they got it.
-
Loosing count on the problems!!

Just 1 - recalcitrant equipment. ;D
-
Into this final leg...
Closeout & Ingress - EV crew then performs a payload bay cleanup, including
EV3’s main umbilical mechanism inspection at the FSS and removal of the two
BAPS post center pip pins, in the event HST needs to be deployed overnight and the
FSS rotated to allow PLBD closure. The crew head to the airlock, where EV4
egresses the MFR. They enter the airlock, install the SCU to the Display And
Control Module (DCM). EV3 closes the outer hatch.

One of the longer, yes, but nowhere near longest. As usual, Bill Harwood maintains some good cheat sheets on the subject:
http://www.cbsnews.com/network/news/space/hstevas.html (HST EVAs)
http://www.cbsnews.com/network/news/space/evastats.html (ISS EVAs)
The longest EVA was 8 hours and 56 minutes, performed by Susan J. Helms and James S. Voss on March 11, 2001, during the STS-102 mission to ISS. They moved a docking port to make room for the MPLM and attach the Lab Cradle Assembly to the top of the lab.

Thanks, everyone for the great coverage. This is one of the most riveting EVAs in a while, and there's three more to go, with the biggee tomorrow!
-
Well thats it for me..
The good news is it is a long weekend in Canada with Victoria Day on Monday (long weekend at the cottage)
The bad news is I will only have dial up access to the internet so no NASATV for me over the next three days.
I will be counting on the updates from this forum to keep in touch with the next three spacewalks...
On the bright side,,, with a long weekend, I will be Barbequing, Drinking Beer and igniting legal explosives (fireworks) in my backyard with my kids!!! :)
Have a good weekend all

A quick Google claims that EVA-1 on STS-102 was 8 hours and 56 minutes. Is that correct? :o
Yes, although that one wasn't all "work" time. They got to spend a little bit of time waiting.

Yes, the EV crew today went above and beyond, but this only being the eighth longest in duration is a good illustration of a long history of crews doing so.
-

PAO saying that the Story Musgrave / Jeff Hoffman EVA was 7:54 in duration. I can see Story saying that the hatch closure difficulties at the end here was just a ruse to buy two minutes, in order to knock Story's EVA off the top 10 list! :)

Got to be said, that was an awesome EVA. They'd of been ok with two RSUs, but even though they had to install a refurbished unit along with the two new units, they didn't settle for the minimum requirement.
Good's debut EVA nearly eight hours, is that a record for a debut EVA?
-
20th HST EVA, making it a total of144 hours 24 minutes.

Not sure what the record is, but John Grunsfeld's first EVA on 103 with Steve Smith was 8 hours and 15 minutes.

Thanks Philip.
I hope PAO restrict the presser to one question each as you'd assume the participants would be completely worn out after today.

Core flush possible post EVA, due to the signature of ice on Pri A - causing it to shut down.
They will conduct the Core Flush. Proceedure on page 322 onwards of the STS-125 Malfunctions Checklist (L2).

Opening comments:
Tony C: Successful and outstanding day. Tile inspection, vehicle cleared for entry. EVA-2 had a few hurdles. We completed all tasks, very happy with that. Crew will go to bed an hour later today, everything will move an hour to the right, nothing lost. Crew getting suits ready for tomorrow, EVA-3 still as planned. All instruments passed aliveness test today. Very good day
-
Tomas: RSUs and battery R&R were tasks today. RSUs had some hurdles. Second did not go as smoothly. Bolts were misaligned, would not engage. Used a spare RSU instead. Crew did great job on battery, some get aheads completed too.
-
Preston: Excited we are 2 for 2 for EVAs. Hit some rough spots, testament to perseverance of crew and Flight Director. Thrown schedule off a little, but can be accomodated. Gyro installation and batteries were accomplished today. Get-aheads set us up well for tomorrow. Things "rolling along", looking forward to tomorrow. Tomorrow is very demanding.
-
David: Two days in a row with "curve balls". Prediction: EVA-3 will go more smoothly than any other. WFC-3 worked well overnight, tests completed well. After mission, will need to wait 3 weeks until real imagery can be obtained. At this stage it is 100%. I think that after 7 years without people, Hubble has gone "wild" again. I view EVAs as 100% successful. We are a long way to extending Hubble's longevity. Thanks to folks on ground and the crew.
-
Questions from JSC:
Q: Does change in gyro line-up affect anything?
A: We've run models for all combinations, difference in longevity is very small. 3 out of 6 are new ones, we don't see this as significant detriment. Tremendous accomplishment.
Q: What made you decide to send the spare?
A: Carry a spare on every servicing flight. Have one that has flown on every mission, and today it got its shot. Called it the "hangar queen". Glad to see it there. It went in real easy.
-
Q: Which RSUs have what gyros?
A: RSU #1 has unit 1005 in it RSU#2 has 1004 RSU#3 has 1006 in it. (Nick - Didn't catch all that on the differences between them!)
Q: The refurb was from 1999, what is the difference between it and new unit?
A: Hubble is only user of this type of gyros. They are the most precise. To keep costs down, we take advantage of existing assets. When we bring them back, we disassemble, and see which components can be reused. We mix and match existing assets, that's how we come to where we are.
-
Q: Surprised by degree of difficulty so far? Could it be related to age of telescope?
A: Don't think aging has been a factor. In case of RSUs, they are built to very tight tolerances, can be difficult to get them installed, need to play with them a little bit. Never gonna understand fully what the problem is. Modified procedures seemed to work, maybe that was the key. In case of latches yesterday, three potential things that could have caused that. Can be tricky to get them to function right. Haven't worked on this instrument is a while, we were being extremely cautious with elevated torque and such.
Tomas: Talking about the fact that "easy" things have been hard and vice-versa. WFC was the "easier" task. Thought RSU problems would be somewhere else. Hope that ACS will have no issues.
-
Q: EVA-3 the most difficult? Comment.
A: Task designed for 2 EVAs compressed to 1 EVA. Task is challenging, due to location of repair, struts in the way. Grunsfeld has trained to do this. Grunsfeld has task "nailed". Talking about challenges faced in 2002 for one of Grunsfeld's EVAs that ran into problems but turned out smooth. Expecting tomorrow to go smooth, task is in their "genes".
-
Q: Is there a sense that things have been building to tomorrow?
A: I expect tomorrow to be "hold your breath moment", but every day has been that so far. Points to the complexity of the observatory. Can't take anything for granted. This is the first instrument repair in space. Any time trying something brand new, the stakes are high, it is "hold your breath time".
-
Q: Schedule adjustments, is this mission more intense than other Servicing Missions?
A: Always hope that it goes well, can hit road bumps. We're always ready for those when we develop EVA timelines. Try to be as efficient as possible, hope telescope will cooperate.
-
Q: Short time where Mass's radio didn't work, what was that about?
A: May have bumped comm switch, changing frequencies. If he hadn't caught that, he is trained to go to airlock and go to hardline, or translate to window, and communicate by writing on paper.
Q: When Bueno took out RSU, he commented that it looked "banged up"
A: Past history shows it takes several attempts to get it seated properly. That was the issue.
-
Q: Since 2 EVAs compressed tomorrow, isn't there additional time elsewhere? If ACS repairs take longer, is there room to finish up elsewhere?
A: We want to finish mission with at least one repaired instrument. If ACS is well along in the repair process, and the next repair doesn't work, ACS will jump in priority. If ACS works just fine, the other repair will drop in priority. Performing more repairs on later EVAs will require looking at spacecraft rotation issue to get access to those instruments.
Tomas: Both instruments at same priority right now, shooting to get ACS done in one day. Have an alternate EVA-5 if both instrument repairs do not work on the first try.
Follow-up: Already 2 hours over EVA time. Is there a limit how much you can go over with back to back EVAs?
A: No, no limit. It is evaluated each day after the EVA. Good news is crews switch each day. Surgeons talk to them every day. Will not take risks if they don't feel okay.
-
Follow-ups at JSC:
Q: Update on FES and how long would you let them go (EVA time)? And how has John done time-wise during training?
A: Know that a 7 hour EVA will not affect post-EVA activities, know that almost 8 hours will, so we added an hour. We plan to 6.5 hours so we have some wiggle room. HST tasks not 5-10 minute jobs. Once you start you need to finish even if you go over time.
A (FES): Worked well the last couple days, possible core is frozen. Put some copper heaters on. Hadn't gotten there yet when I left, but we have backup system.
A (Timeline): John has gotten it done in the pool. ACS wasn't designed to be fixed during EVA, accounted for additional time for that. Have been conservative in timeline estimates, in case things get jammed. If everything goes smoothm John can finish in under 6.5 hours.
-
Follow-ups
Q: ACS Aliveness test, does it take longer? Excitement level for tomorrow.
A: Don't recall exact time for aliveness, probably similar to other instruments. Baselined for 10-15 minutes while astronaut is present.
A (COS): COS is most sensitive spectrograph ever to fly. Not as fancy as a camera, but very precise. COS focusing on UV spectrum. COS is very sensitive. Specs don't get respect that cameras get.
-
Last question: Other RSUs fit, maybe a problem with unit 007? Any indication of this in the past with 007? How much did the unit cost?
A: Nothing in the contract that says taxpayers get money back :D
They are built to very tight tolerances. Can find it challenging to install. If we had more time, maybe it would have worked.

Question regarding the ACS repair. Why do they replace the cards with the ACS still inside Hubble? Wouldn't it be easier to get access to the ACS if they first remove the instrument and replace the cards while it is outside of Hubble? Then when the job is finished they just slide it back inside Hubble.
I know that there is a good reason why NASA do it this way, i just cant figure it out.
My first post/question after 1 year of reading so forgive me if this is posted in the wrong thread.

Likely because there's the risk of screwing up the optical alignment of the mirrors (which is critical) or even damage to one of the mirrors or mirror supports during removal or reinstallation.

Welcome on board!
Some other reasons for doing the repair inside Hubble is
1) To shield the repair from the varying thermal environment going from day/night/day.
2) The lighting can be more uniform by using the EVA's helmet lights & visor up instead of messing with all that in the middle of an exposed card carrier.
3) Reduced mmod risk by using Hubble as a shield.
