Today's EVA 4 summary timeline from EVA Checklists - will update if it changes in FD7 execute package (not yet posted as I type).

From nasa.gov:
Space shuttle Atlantis' crew awoke today to “New York State of Mind” by Billy Joel at 5:31 a.m. EDT. The song was played for Mission Specialist Mike Massimino.

Edit: And here are the mission summary timelines for today.

Updates on HST scientific instruments from the execute package:
We ran the ACS functional test tonight with great results. The first part of the functional test
dealt with the new hardware, and this part passed with flying colors. The new CEB-R
controlling the WFC channel is working with significantly less noise than before. The second
part tested the entire ACS instrument and it hit a snag when we tried to backpower the HRC
channel. So early test results say we have an operational ACS with a functioning WFC
detector.
COS successfully completed its functional test. All electronic and mechanical systems along
with the detector are operating beautifully. We believe this instrument is now running better
than the PI, who is on his fourth glass of champagne.

I would like to ask for sth.. yesterday after moving John and his mate to airlock I have found that note (dont ask me from where ;)) :
"EVA ENDS. Repressurization of the shuttle's airlock module began at 4:11 p.m. EDT, marking the official end of today's spacewalk"
I thought that the official mark for finished EVA is switchin both astronauts from their battery in EMUs to shuttle net, furthmore I thought that in this way it happend on ISS so far. So how it goes ?

Yeah, its a bit confusing. EVA start is when they switch to EMU battery power, but the end is when re-pressurisation of the airlock begins.
At the end of the EVA after the airlock hatch is closed, they switch to external (orbiter) power source and a little while later switch comms from radio to a wired link (at which point we no longer hear the ongoing procedure callouts by the astronauts). A few minutes later the re-pressurisation begins, so officially ending the EVA.
This is how it is done for ISS EVAs as well.

Some additional notes from the FP Walkthrough document:
Egress & Setup: Both crew perform MFR setup, which EV4 then ingresses the
MFR at the airlock. EV3 translates to the ORUC to retrieve the Fastener Capture
Plate (FCP). EV4 meets EV3 at the ORUC and receives the FCP and installs in onto
the Multi Use Tether End Effector (MUT EE) /ballstack. EV3 installs the two BAPS
post center pip pins, that were removed at the end of yesterday’s EVA, and
translates to the fwd/port FSS.
-
Mass ingressed the PFR. PAO identifying white cable as cooling loop for NIS
-
And into:
STIS Repair - A complex task utilizing a wide variety of tools. EV4 rides over to the
+V2 doors and opens them with EV3’s assistance. The crew will prep the Main
Electronics Board (MEB) cover for removal. EV4 retrieves the STIS tool disposal bag
from the ORUC. EV3 removes the STIS handle bar so that the MEB cover and
LVPS-2R can be removed. The Handrail Removal Tool (HRT) is used to contain the
fasteners and debris generated from faster removal. The MEB cover extension
clamp is removed. The Clamp Removal Tool (CRT) contains fasteners and debris.
EV4 retrieves the a Fastener Capture Plate (FCP) and hands it off to EV3. EV3
installs the FCP onto the MEB cover to facilitate removal and capture of the 111
fasteners. The MEB cover is then removed to allow access to the failed LVPS-2
electronics card. The MEB cover and FCP will be returned. Meanwhile, EV4
retrieves a new LVPS from the SOPE and translates to the aft shroud. The failed
LVPS-2 card is then removed by EV3 and handed to EV4 for stowage. EV3 receives
the new LVPS card (in a soft transport enclosure) from EV4. He then installs the
new LVPS-2 card into the MEB. He then retrieves the new MEB cover from the
ASIPE and installs it. The +V2 doors are then closed..

Bueno getting ready to pass RIB caddy to Mass
-
Next step is to remove 4 screws from the left and right sides of the MEC cover panel so that 4 guide pins can be installed to hold the FCP later.
First Mass needs to install some retaining clips using the RIB tools and the mini-power tool that will hold some washers in place.
Then the four screws will be removed, followed by the washers with the WET tool.

The first 6 tools were installed with the mini power tool, yes the 7th was manual.
Yes the guides (anchors) will be installed once the handrail is removed.
And the removed fasteners are going into a disposal bag

MCC-H wants spare bit rather than trying to redrive with this bit
-
MCC-H requesting to get the new hex bit
-
How far down are we on the timeline?
-
MCC feeling is that a new bit will be more likely to "bite" into a worn head because it will have "sharper" edges on the hexagon sides.
Looking at other contingencies on the ground

Current PET is 2:05, are due to begin MEB cover removal on the original plan at 2:10.
Still need to remove that handrail and install 4 guide studs (two "zipnuts" and two "wingnuts") and the Fastener Capture Plate (FCP) before then.
-
This might be dumb question, but if 3 of the 4 bolts are released, why not rotate the handle on the remaining bolt and rotate it out of the way. Or even shear it off?
And why didn't they get the spare bit out of the box the first time?

Sounds like the troublesome bolt's head is damaged to the point the previous bit was slipping, so the larger one should do the trick. I think we've all had screws etc like that during various DIY fun (though not in micro G and wearing EMU Gloves! :o)

1) This might be dumb question, but if 3 of the 4 bolts are released, why not rotate the handle on the remaining bolt and rotate it out of the way. 2) Or even shear it off?
3) And why didn't they get the spare bit out of the box the first time?
1) Was my first idea too.
2) Maybe you do damage.
3) You can't plan for everything.

We all know situations like this: Once it is no longer hex (or whatever it was before), it is pretty much a circle. Your tool just turns. I still like the idea of rotating the handrail [EDIT: This probably won't work because the handrail seems to be sitting in some kind of socket and not flat on the surface].

Mass noticing debris, so that's obviously a broken bolt head. You can see it slipping about 180 degrees of the PGT motion.

Can't get plate on with hand rail, so rotating it out of the way isn't an option.

"Tight fit thats why we gotta get it off"

Someone correct me if I'm wrong....
Bottom left can come out.....
Bottom right is a relatively small "hex bit, round head bolt". Anyone know made of what?
Why can't he undo the bottom left... and then just man handle the thing off...... or worst case rotated it out of the way...

Talking about shearing off the bolt.

Vice Grips, getting some free advertising.
I had an Australian engineer I worked with who called them "footprints"

Make no mistake, they have saved me in several situations like this!

Finally, MCC-H gives the go to break the handle off when they get back
edit: Well almost a complete go
-
I can't believe they want to pull the handle now to shear the bolt! Option being considered. Definitely a new NASA mentality. Love it.
-
Also discussing leaving just lower right bolt in place, pulling from top, possibly shearing stuck bolt off. Think it might take about 14.5 foot pounds to break bolt.
Would need to be very careful!

yeah! shear it off. Bring it on! Brute force all the way.

Stored energy inside the telescope in a tight space is the primary concern.

Goddard saying it took 60 pounds of pull to break the bolt off.

60lb force require to break the bolt, thats pretty massive
-
Wow, they just simulated it at Goddard and it took 60 lbs of pressure to snap it off.

Goddard saying it took 60 pounds of pull to break the bolt off.

Sorry to interrupt the flow of the posts, but how come he is able to move so fast between sites? Shouldn't he be using the "always tethered" rule? I didn't see him using the tethers from the tool box back to telescope.

No further risk so "back to your normal programming"

EVA 5 is 5:45 nominal planned. So there is time. I wonder since day 1 why NOBL 5 is not in the nominal EVA plan with 45 minutes to spare.

Sorry to interrupt the flow of the posts, but how come he is able to move so fast between sites? Shouldn't he be using the "always tethered" rule? I didn't see him using the tethers from the tool box back to telescope.
If you can redirect to a simple answer thanks!!
He is tethered. There are EVA tether guide wires above the sill of the payload bay on both sides. The primary reeled tethers of the free-floating person are hooked to that.

Thanks for the info!

Have there been other EVA's where they have gone back to connect to the SCA to "top up" with more oxygen?

I think I head the limiting consumable will be Bueno's batteries.
-
Hahaha.. nice shot Chris ;D
-

I think I heard that the ground wanted Mass to do a suit O2 top off while he was back at the airlock, so that the limiting consumable would be Bueno's suit batteries at 9 hours.

Yes, and I believe that they just did this on EVA-2.

Talk about a sideways EVA...this is starting to look a lot like Apollo 16 when John Young and Charkie Duke broke just about everything they touched...Mass is starting to sound a bit pissy...I don't know if he was going back in the rotation or not, but I can't see him flying again...

The good thing is that they are close to the airlock. It's not like the ISS where they are concerned with all the tether swaps and such, delaying their translation along the outside of the modules.
Difficulty is a good reminder of why they are there. They may be sounding frustrated, but they just want things to go as smooth as possible to get the job done faster, for either get-aheads, or get out of those tight and uncomfortable suits too.

Do you work for the AP? ;)
The bolt head was likely ground out from its installation and comparing it to an EVA where everything they touched, they broke - is polar opposite to this mission's EVAs.
It's hardly the easiest of tasks ever conducted on an EVA and any sense of frustration is because he'll have his own very high standards for getting the job done....and he's not being helped by some of the hardware.

Mass O2 recharged - heading back out to work.

Does Bueno need to go to airlock for recharging? :-X

This whole mission is a poster child for the argument for 'man in space'. Can you image any robotic mission accomplishing what these spacewalks have ? These guys are doing a phenomenal job!

Just a quick add: But we are LEARNING what works and what doesn't...for EVA's, maybe even for future robotic repair missions. NO 100 SCREWS! 4 screws & latches only...or something along those lines.

These guys are doing a phenominal job! I know mass is getting stressy, but he did just put himself at quite a lot of risk when pulling off that handle. Do any of you know when in the timeline we will have to give up on this job? i.e. When do we have to have this plate off to give us a chance of completing the task?
-
Yeah, I can't imagine that robotic mission they were trying to put together succeeding with all those stuck bolts and other issues.
No need. They launch two, are still at least one magnitude more cost effective, have one failing (or not) and get the same or twice the output.
Absolutely correct. I know there's a few geeks who get overexcited about a Rover moving 10 feet between rocks of different sizes, but this is real space flight and this is what NASA is all about!!
I know a few geeks who get overexited about HSF. Right now. :) They forget its very bad cost vs. benefit ratio.

Excellent points made on durability being built into devices such as HST. I know its wandering off topic a bit, but as we wait for things to get started again, I would say that flexibility is the key here. HST was certainly not designed for the duration its been up, but maximizing the investment is worth the effort. This is far better than letting this thing splash into the pacific ocean now that getting another 5 years out of it.

Glove inspection OK. 4:29 into EVA, approaching orbital sunset over southern Africa.

Oh please. This is unwarranted attacking of "geeks" who follow robotic missions. You may be a fan of the manned space flight, but those puny rovers you mock do science at a place a human will never see with his own eyes for the next 20 years. Think about that the next time you complain about the glacial progress they're making in the context of science/dollar produced.
There's a place for human spaceflight and there's a place for robotic missions. This rivalry and taking potshots at the other camp is just childish and sickens me.
-
With all the hold-ups they are about 2:20 down on the nominal timeline as they now start the MEB cover removal task (but they were able to dump some tools at the airlock just now which saves a little time later on)

Has nothing to do with it, imho. The point is the actual EVA work being conducted, not the rationale for a spacecraft that needs the servicing. This is all lessons learned, and the experience will apply to future missions in decades to come, because it'll be decades before they can create robots to have the ability to compete with the hands on human ability.
Anyway, live thread, a sep thread can be created for a discussion on this.

Physicist, not engineer. We measure everything in energy and set h=G=c=1 :-)
And in general 1 Nm = 1 J anyway.
But OK, if the poster was talking about a torque measurement, rather than
force x distance = work done, Nm is conventionally considered more appropriate than J, although it does correspond to the energy in J for turning something through one radian, and cosmologists tend to think more in those terms , apologize for any confusion generated.

IMHO, totally uncalled for on two counts. First, Mass has been sounding far less annoyed than most anyone, including myself, would sound in the same situation. Second, Young and Duke broke exactly one thing by accident, the HFE cable. (Well, OK, a rover fender came off, but that happened on all three J missions.) Anything else on Apollo 16 that performed below spec was because of poor design or manufacture, not improper use of the equipment or accidents.

Was is completely dead before they started?
Dead (well in safe mode) since August 2004!

Many thanks Chris for this list.
Next amazing spacewalk is slowly going to finish :)

Can anyone here recap on what's completely done, what's not?
In particular, I'm a little hazy on if all three of the ACS are done? Any chance for HRC or is that toast?

That comment just made me chuckle:
EVA: "Time for me to go inside?"
Houston: "Yes, time to go inside"
EVA: "But its such a beautiful day outside"
LOL!
As my better half just said, that must be the Astronaut equivalent of "Awww, mom, do I have to?" :)

I suspect that will be asked in the upcoming briefing, but this morning Bill Harwood quoted some commentary from the Orbit 3/Planning PAO overnight that didn't sound encouraging:
http://www.cbsnews.com/network/news/space/current.html
"The wide field channel was tested this evening, that was the major focus of the spacewalk yesterday, trying to get that channel back up and running," mission control commentator Josh Byerly said early Sunday. "The payloads officer confirmed that everything looks fine on the wide-field channel. So good news on that front.
"The high-resolution channel, however, ran into some issues, some power fluctuations were seen. ... They did confirm the short in the wiring of the high-resolution channel was actually upstream of where the astronauts were working yesterday. What this means is the repair was not successful on that specific channel."

Bueno coming in to airlock right at sunset.
Great job guys!

STIS has safed itself after reaching low thermal limit (did I hear that correctly)?
Will repeat functional test.

I assume there's some pretty touchy current protection so the HRC won't take the WFC that's feeding it out. I'm not sure, but I think they didn't rule out the HRC as being the cause of the side 2 PS failure in the first place. If the glitch is the current limiting kicking in, it wouldn't be good.

Think so. They're going to let the temp sensor warm up longer on the second try.

Wanna ask - why they change orientation of shuttle to -ZLV +YVV right now?

She works a Sun Protect attitude during the EVA to protect the space walkers from the sun.

Great coverage again everyone! Sounds like this EVA needs to be on HGTV's "Renovation Realities."

Great EVA coverage guys. Thanks!
Quite to challenge for EVA tasks.
One planned EVA left and we can set Hubble free. :)

You kinda had to expect that yesterday's smoothness was not too likely to be repeated.
Great updates folks, thanks a lot! To summarize, they eventually completed the STIS task (after ripping a stripped socket-head-cap screw head off by force) and didn't get to NOBL, correct?
-
PET 8:02. 6th longest in US spacewalk history.

Wow, what a mission! :)

Correct. Completed STIS, no time for NOBL.

HST rotated to +V3 side forward.
-

Yes I know (by the way are there also small changes in orientation of Atlantis hidden under "Sun Protect" phrase?).
Imo I don't get it why shuttle is changing this "-ZLV +YVV" into this "-ZLV -XVV". These orientations are connected with lowerin risk of MMOD impact?

So no hope for HRC because it is the proximate cause, and we've no plan for repair.
Does that mean it needs to be isolated to keep from killing WFC?
Thanks
-
Oops, HST is in -V3 side FWD. Will rotate to +V3 FWD.

I've been amazed how much they are getting out of these EVA's. Messing with a cranky old satellite like this is impossible work.

So is NOBL on the cards for tomorrow?

One NOBL is planned. Others will likely depend on how the battery and FGS swaps go on the timeline.

The HRC card bay is separate from the wide field bay - they'd have to have done an identical repair for it as they did for the wide field to guarantee success.
They had some hope that there wasn't a circuit short downstream from the wide field power circuit (going to the original power supply) so the HRC low power circuit could be 'patched in', but it apparently turns out that wasn't the case.
So, yes, the high res camera will be no more.
-
HST rotated to +V3 side FWD. Visually the insulation on Bays 7 & 8 looks degraded.
-
Megan says the outer insulation on bays 7 & 8 appears to be pretty torn up.
(first time they've had a view of that area)

Couldn't get a screenshot in time, but Dan Burbank needs a better background image on his PC. He was logging off and I was expecting a nice shuttle picture, not the default green hills picture :)

Eh, depends on personal preference, really. I have a rather bland blue pattern background and don't bother with pics - it helps to easily see the desktop icons, and since I always have at least one browser window open covering 60% of the screen, and usually others open as well covering much of the rest, there's no sense having a background picture I'll never bother looking at. :)

The right-hand bay (bay 8 ) was the NOBL replacement originally scheduled for this EVA.
-
Talk about the plan for tomorrow coming up.
-
Interesting listening to this little planning meeting for EVA-5 between Tony Ceccacci, Scott Altman, and John Grunsfeld.
Talking about a partial NOBL 8 and full NOBL 5 as baseline, but crew lobbying to be ready to do a full 8 and full 5 if the high priority tasks (batteries, FGS) go ahead of the timeline.
Sounds like they will see where things are tomorrow when they get the FGS task done.
Mission Status Briefing now targeted for 7:30 pm Eastern.

That's a good characterization.
And you're right, it was fascinating listening to the Flight Director. Isn't this the second time he's done that on this mission? How often does a Flight Director speak to the crew?

I like the Adam Riess quote in the NY Times article:
http://www.nytimes.com/2009/05/18/science/space/18hubble.html?hp
Three of the bolts holding the handle on came off easily, but Dr. Massimino could not get traction with his drill on the fourth bolt head. After fussing with the bolt and then retrieving a new sharper drill bit from the airlock, he asked, “What’s Plan C?”
After a discussion about which way to apply tape to keep the broken bits of bolt from flying off into space or the telescope, and a review of the yanking procedures led by Commander Scott Altman, Dr. Massimino allowed that he would probably rock the rail back and forth once and then go for broke. As it happened, the shuttle had passed out of television range of mission control and an interplanetary audience.
“It’s off,” Dr. Massimino reported.
Adam Riess, who was watching on ASA TV and is a heavy Hubble user at the Space Telescope Science Institute and Johns Hopkins University, wrote in an e-mail message: “We always joke that they wait until they are out of TV view to use the hammers and crowbars . . . I guess they really do!
[edit]...they could use an editor though.... "could not get traction with his drill" "retrieving a new sharper drill bit" "an interplanetary audience" "ASA TV"
-
The "interplanetary audience" part is fine...they were at Mars this morning. ;)

Tony says they'll do partial install of the NOBLs, and will increase how many they will do as they go.
Tear in Mass' EMU glove, possible start of a hole. No concerns as they've isolated the area where it happened.
Tomas: Any one thing along the path can put a stop to everything, and it could have happened yesterday.
Repeats what happened, that we already know, and shows his own handle. Didn't think this would cause a problem. Rest of the EVA went well.
Quote: "This is why we have humans in space" (damn right).
-
Tony Ceccacci: Testament to the team. PET 8:02. Talking about replan for tomorrow. Baseline is to do partial installs of 5 & 8. Protect capability to do full install. EV3's right glove has a cut.
Tomas Gonzales-Torres: Today didn't go quite a smoothly. Went through a lot of discussions on the handrail bolt. We fatigued the fastener until it broke off. It was very exciting when we got through this, a testament to humans in space. The rest of the EVA went well. Crew did a phenomenal job.
-
Preston (HST) is happy they repaired STIS. Liveness test shows functionality. Functional test had a bit of a glitch (low temp violation), and put it into a safe mode. Will restart when it warms up, all looking encouraging.
Today reminded Preston about when he goes to his driveway and tries to fix his car. Understands Mass' frustration. Speaks about the handrail they have at Goddard that they tested the snapping of. "When it broke it just went "KER-PANG!!!" and then bounced back the other way," so glad it didn't do that with Mass.
35 tools - all new - used for the repair.
-
Jennifer, Chief of complicated science (she has a long title, didn't catch it), is happy with Hubble capabilities being brought back on line. Talks about sciency things and is excited about looking for methane etc on planets far far away.
-
Jennifer's enthusiasm was abundantly apparent in her talk.
-
-
Preston didn't think they would have someone the size of Mass wrenching something off Hubble. Suspects he was pretty upset with Hubble was pumped up for the task.
ACS Hi Res channel has not worked yet, but that was a 50/50 situation and a bonus if it had worked. No hope of seeing that come back, but there was no way to predict from the ground.
-
They said that was a 3/16" (socket-head-cap, I think) Stainless screw he ripped off of there.
-
Tony talks about e-mails between himself and Scooter at the end of day, and notes they are all still very much on the same page.
Tomas says the same, says they are all on sync.
-
Fluff questions, then Robert asks a couple of good ones.
Glove hole (starting of a) is in the crotch area, no problem, not going back to that worksite.
No concern/requirement over the lack of Ku during Mass' handrail pull.
-
That's pretty much it.
Wake up tomorrow 4:30am Central (10:30am UK).
-
This constant armchair spacewalking is really starting to wear me out... Well done to the crew and also to the posters here! One more to go...
-
(HD highlights being downlinked now.)
PAO Pat Ryan offers one reason for the last EVA duration being baselined at 5:45, which is that the crew needs to begin sleep-shifting back towards de-orbit. (And the timeline was already shifted forward an hour due to the length of EVA-2.)
-
...looks like we may get to see onboard video of Mass'es busting the bolt... showing now on NASA TV
[edit] ...darn the downloaded video didn't get the actual bolt busting moment.

thanks for the past two days of coverage guys... the only way for me to catch up on low speed dial up this weekend is this forum... well done all.
btw - when are the SRB video's going to be out or have I already missed them??
-

You haven't missed them. I think it's more that they were recovered for the imaging team right before the weekend started, and there's no sources or PAO folks available to make them available for public viewing yet.
Hopefully late tomorrow.

I just wrote a short update about this, complete with a photo of the handrail and bolt example that Tomas Gonzalez-Torres shared during the briefing: Flying off the handle, revisited (http://www.collectspace.com/ubb/Forum30/HTML/000790-2.html#fd07g)

Standing by for STOCC briefing on the status of the telescope after today's spacewalk
-
Update of the Spectrograph tested both minds and muscles.
120 screws to remove. A handle prevented the removal of one screw.
Video of pulling the handle off at Goddard pretty impressive. Must have been fun on the telescope.
The replacement spectroscope is working well.
Overall a fantastic effort. 99% success.
First big challenge tomorrow is the batteries.
Then the fine guidance sensor.
-
Then comes the outer blanket installation to replace degraded insulation.
Very pleased to have instruments working tagain.
(Sorry, I did not get the briefers name.)
-
Then a background video on the FGS and the NOBL. Believe the new insulation material should last more than 20 years in space weather.
