Reboost ? After completion of EVA-5, or overnight?

Reboost ? After completion of EVA-5, or overnight?
Unless there's a drastic re-think to put it back in, reboost was taken off the table in the final planning for the revised mission to save as much propellant as possible (because of the increased MMOD dangers).

what? are you sure? this paper says without reboost the orbit will decay by 2013... didnt one of the mission guys say they hope to get possibly 10 years out of HST?

The figure I heard most often was a guaranteed extra 5.

The figure I heard most often was a guaranteed extra 5.
guaranteed extra five assuming no solar flareups? even then i woudlnt think they would say 5 possibly 10 years if they know the orbit will decay without reboost. and it seems silly to go thru all that trouble to reach and repair hubble and then not reboost it.
-
Browsing through the decay tables, I see that most satellites at Hubble's present altitude last around 5-15 years

Might be being thick here (I'm sure you'll tell me), but given that we'll be 8 days through an 11 day flight after this EVA (and some of the remaining days will be spend at a lower altitude), can it not be assumed that most of the MMOD dangers (and therefore the need for propellant to avoid them) has passed? What I'm saying is, I agree it would be a shame not to reboost.

Maybe not reboosting Hubble will reduce the risk for the telescope as well in the long run.

Today's mission summary timelines.
(Outer blanket layer tasks listed as NOBL 5 and partial NOBL 8 for the nominal plan, with no change to planned overall EVA duration of 5:45)
-
Crew advises no PMC required.
-
Today's spacewalk to kick off at 8:16 and is scheduled to last 5 hr 25 min.
-
Suit preparations continue in the shuttle airlock. Verified biomedical data link with MCC is good and EVA1 and EVA2 radio checks good.

MMOD risk is not the reason given by the people at the news conferences. The reason for no reboost is that the current solar minimum has been especially quiet and a reboost was not required. The reboost sheet posted above is almost six years old and the solar flux predictions have likely changed quite a bit since then.

Reboost: There is an inconsistency in NASAs argumentation, something repeated here. If MMOD risk is not the reason to not perform a reboost, when what is the reason? More landing opportunities? A reboost would buy time, time for a longer HST lifetime or a longer time to develop a deorbit strategy. A reboost was always planned, until a few weeks ago. It costs nothing. Risk is not a factor. So why not do it?
The "not needed" argument is pretty lame: NOBLs are not needed, but desired. Who knows the solar flux in the next decade? Who knows how long HST will operate? To many questions to not use an option which costs nothing.

EVA 5 Summary timeline (my annotations in red). I've checked the timings from today's execute package and there are no changes to the original task durations shown.
Edit: PAO announced a 20min extension to the EVA after I posted this, so reckon on stretching the NOBL task shown from 30mins to 50mins.
-
Whats about NOBL 7? This option will be take to consideration if time permits or has it already been dropped?
-
Just heard a comment from PAO that we now had a 6:05 duration for todays EVA and NOBL7 was still in there on an "if time permits" basis.
-

Could it be the shortage of proppellant ? You need some of it to the de-orbit burn at the end of this mission.
Or may be the structure currently holding the HST in the PB (FSS+SCM) can not endure the loads of the reboost ? The HST has a significant mass and could exercise a great ammount of torque.

The structure is not an issue. This is the same thing used on the past servicing missions, and I think all of them had a reboost.
-
Water dump in progress..
Like Fred Haise in "Apollo 13" movie said "Its like a new constellation of urine!" :D
-
Just heard a comment from PAO that we now had a 6:05 duration for todays EVA.
The NOBL 5 task is nominally 30mins, and the original NOBL 8 (dropped yesterday) was 45mins. The extra 20 mins now added to the EVA overall duration still means not all the NOBL 8 task is planned for - but of course if they get ahead of the timeline ....
Edit: And of course there may be significant time savings through shared set-up & tool use.
-
Yep, we can hope.
Meanwhile, the scene of action awaits although it remains to be rotated to bring the worksite forward. Crew has go ahead to rotate.
-
EVA purge in work. Listening to the calls, it sounds like the crew is trying to get out the door early.
From listening to some of the discussion yesterday, it sounded like the "limit" on the EVA was mostly due to making sure the crew got to sleep on-time vs. an EVA duration/consumables issue. (They need to sleep shift to sync with de-orbit at end-of-mission and the timeline is already pushed forward an hour due to the length of EVA-2.) Starting early would give them more EVA time while still allowing the post EVA activities to fit into the schedule.
-
Preparations seem to be about an hour ahead of the timeline
-
Crew about ready to commence rotation of the telescope. Unfortunately we have no pictures just now.
-
With WFC3 being able to work with far shorter exposures than WFPC2 I wonder if they're considereing planning observations to keep the aspect to the direction of travel down to keep drag minimum. With improved gyros there's an excellent chance she'll be just fine in ten years.
-
Crew has commenced 40 minute prebreathe. Clock started at 22 past
-
There is now an 8 minute comms gap and this appears to have triggered a mass exodus of the orbit 1 crew. Coffee or comfort I guess :)
-
Telescope has been rotated.
Crew also has go to perform the maneuver scheduled for 18:30 early at their convenience.
-
A period of ratty comm coming up. EVA has been given the goahead to commence depress on time at 1802 if comms are unreliable at that point.
-
Go for depress cue card
-
Confirmation of commencement of depress. Depress has begun.
-
5.0, depress valve to off
-
Go to depress to zero
-
1.6 psi
-
0.6
-
Go for outer hatch opening
-
Hatch is down and locked, valve closed
-
Power to batteries, the EVA has started!
-
Morning guys!
Just a quick question for tomorrow's rendezvous, in the flightplan they're talking about the HST DPY manual for procedures, where can i find this doc? (normally they're working with the rendezvous manual right?)
Thanks!
-
EVA officially started at 0720 CT
-
Ready for egress.
"Go and be productive"
-
Drew is out. How does it look out there? "It looks dark"
-
"How's it look out there, drew?"
"Looks dark!"
-
Feustel has all white suit and is camera 20. Grunsfeld has solid red bands and is camera 19.
-
Cool -an hour ahead of schedule should give them enough time to complete all tasks, including all 3 NOBL's if everything goes to the timeline and there are no hold-ups shouldn't it?

Drew is moving around rearranging tethers
-
Grunsfeld is now out also.
-
Ansd is in foot restraints
-
Thermal cover
-
-
John heading for the batteries
-
Tether checks complete and the arm is in motion
-
I notice that they both have the mirrors on their gloves (near the palm), so they can peer behind things. Anybody know which part of the EVA these will help with?
-
Views from Johns helmet cam.

i think they are for reading various gauges on the chest of the emu.
-
And the door is open.
Fourteen bolts and six connectors to go!
That block battery bos is about 36 by 36 by 10 inches and weighs 475 lb.
-
I notice that they both have the mirrors on their gloves ...?
i think they are for reading various gauges on the chest of the emu.
Thanks, now that you mention that, I remember hearing it before.
-
First two connectors removed and capped
-
A better view of connector and a wider view.
-
All the connectors are now demated
-
Meanwhile we are still orbitin Mars :)
-
There's some sweet helmet cam images coming down. I'm not going to be able to contribute too much to this thread as I have to go to work in an hour but I've got a couple of offerings:
-
Now working on the bolts
-
Here's a nice shot with the wing and the tail in the background:

which is why some of the labeling on the EMU chest is reversed
(from http://spaceflight.nasa.gov/gallery/images/shuttle/sts-125/html/jsc2001-02670.html)
-
Three bolts to go
-
All bolts out and the battery is off the door.
-
In transit back to the cargo bay. Megan doing a great job on the arm.
-
Old battery handed off. John has the new battery. Connectors inspected and confirmed clean.
-
Getting close to the telescope with the new battery. We will be without video for about 20 mins.
-
Drew is bolting the old battery into the carrier.
John is working on the new battery bolts. Has the first bolt in and is untethering from the battery.
-
Money shot!
-
Just over an hour and a quarter into the EVA. Bolting of the new battery is proceeding without a hitch so far. Turn counts and torque are all as expected.
-
The CG display of the arm positions. Working very close to the telescope withthe arm.
-
I'm wonderin if they will fit in 1.5h time for this task. Seems that they are right with timeline so far..
-
All bolts complete on both batteries. John working on connectors and Drew on the thermal cover on the old battery in the cargo bay.
-
We have again video..
-
John working on connectors and isolator switches. All three on. Go to close the door
-
Door closing. "bye bye battery"
-
Bay 3 aliveness test on batteries sucessful
-
STOCC has reported a good aliveness test on the battery.
-
Debris?
-
Looks like they are about 1hr15 ahead of schedule now?
-
Battery bay closed, bolted and task completed - about 20mins ahead of the timeline
-
moving on to the FGS
"beam me down" :)
-
Battery replacement is complete
-
Now doing some tool exchange and stowage to prepare for the FGS task.
My rough estimation is that they are ahead of the timeline.
-
They have declared minimum mission success for the HST SM. Coming up on orbital sunrise near the Baja peninsula.
-
John translating to the telescope on the arm. Drew configuring the temporary stowage rack for the old FGS when it is removed.
-
Now moving on to the FGS replacement, the last major task of the mission. And with this I'll sign off and go to work.
-
For reference, the next phase of the FGS task (opening the bay doors) was nominally planned to happen at 2:10 PET its 1:51 now so still about 20mins ahead.
-
The orbiter from John's perch and a good glove check. Drew appears to be enjoying the life of a free floating astronaut.
-
-
Wil have to get this picture later:
-
Door latch bolts not releasing - increasing torque settings on PGT to break torque
- OK that worked, back to nominal torque setting
-
Latch bolts on FGS cover proving too much for the PGT. Will try stepping up torque
Drew is now up on the telescope.
-
Broke the torgque, going bakc to nominal settings
-
Now moving on to the FGS replacement, the last major task of the mission. And with this I'll sign off and go to work.
Okay, thanks for the coverage!
-
Ssecond bolt easier, no need for higher
-
-
PGT ratchet mode or EVA ratchet are the next options to break torque.
-
Sounds like they got it. I believe with the EVA ratchet.
-
Gone to the EVA ratchet for the third bolt. That did the trick.
-
2hr2min into today's spacewalk.
-
Sounds like they got it. I believe with the EVA ratchet.
Confirmed :)
-
Waving to Houston and taking pictures of the crew in the cabin windows.
-
FGS:
-
Doors open and FGS visible. Confirmed lights are off.
-
All connectors demated. No pictures just now.
-
Breaking torque on the A latch with the ratchet.
Now 2:12 into the EVA so still well ahead.
-
Cables disconnected and moved out of the way.
Clamp bolt is proving difficult. Going for the contingency MTL to give more leverage.
-
John moved away from the telescope and preparing the new tool
-
Uhh.. rly nice! OMS on the background :)
-
MCC: Go to use the contingency MTL
-
John has new tool configured and is returning to the worksite.
Still no joy so now going to remove the torque limiter from the tool and apply direct force. Asked to try to make application of torque as smooth as possible.
-
Reconfiguring the tools again, over the coast of central Africa
-
That did it. Now going back to tool with torque limiter
-
Now have the FGS handhold and moving back towards the teleacope
-
"And now back to our regularly scheduled programming."
Not the first time we've heard that on this mission.
-
The handhold in place and being screwed down.
-
Now unscrewing the clamp bolt the rest of the way. 22 turns. FGS is now free and being removed
-
FGS away!!!!
ETA: IMAX 3D shot of the removal, can't wait to see that!
-
Now clear.
-
-
John translating totemp stow the removed FGS.
Now on the EVA timeline.
-
-
-
With the slight holdups on the various latch bolts, they start the FGS-2R retrieval task bang on the nominal EVA timeline.
-
Nearest 18 minutes without video signal as PAO said..
-
No images for about 20 minutes.
Its well past the pumpkin hour here so I'm off for my beauty sleep. I look forward to catching up with the rest of this tomorrow.
-
Thanks Selwyn - and everyone helping with the coverage. I'm snowed under with things for another hour or so yet, so great team effort again.
-
No images for about 20 minutes.

Okay. Thanks for all your great images and coverage!
-
Think they said, if they continue at this rate, they're going for a plan to do all 3 NOBLs!! Great news.
-

Yeah, they said they will have a tag-up with the EVA team later to decide on the forward plan, but NOBL 7 (originally a get-ahead task) was definitely on the table. Its nominally a 20min task according to the EVA checklist.
Edit: For reference, the FGS task is due to be completed at 4:00 PET so we'll see.
-
The HST guys will have to be HAPPY if they get all that. Can't of had too much hope they'd get the whole shooting match.
-
FGS installed. Now mating connectors.
-
How much of a get-ahead would be needed to finish off ACS?
-
How much of a get-ahead would be needed to finish off ACS?
None. No spare parts for HRC.
-
Ah, drat... There's forward planning for you... :-)
-
Some trouble with the connectors...
-
Hee.. "Thats the classical Hubble thingie.." Yep, John knew what he said ;)
-
connectors mated. Closing doors.
-
FGC-2 finally connected, now the door is being closed.
-
Doors are closed. Retrieving old FGS.
-
"coming over Hawaii" ... "I guess that's where those jets are going."
Can they actually see airliners? Maybe the contrails?
-
"coming over Hawaii" ... "I guess that's where those jets are going."
Can they actually see airliners? Maybe the contrails?
You can see a space station on orbit, so it is possible to see a jet that is 10 miles closer to them
-
Should have known as soon as I thanked people for teamwork that all the screenshots would have gone AWOL!

OK... but the space station is only visible when in sunlight against a dark background IIRC.
-
Whats wrong with these clouds down there? ;D Like a bubbles..
-
Heading over the US shortly.
-
FGS being stowed, heading over Texas:
-
Galveston Bay...
-
Going to have that ground tag-up very soon to decide on NOBL plan.
Timewise it looks like they are just over 10 mins ahead of the nominal EVA timeline at the moment
Edit: MCC-H notes that ~1 hour ahead on the MET timeline and this is what will drive the overall duration
-
Should have known as soon as I thanked people for teamwork that all the screenshots would have gone AWOL!
I would if I could....
I'm lucky to have a stable 19k connection right now to simply listen and refresh this site every few minutes...lol
-

They're much further ahead of the day timeline due to starting early, correct?
EDIT: CAPCOM just confirmed they're over an hour ahead!
-
Go for all 3 NOBLEs...
"How about you Drew: you all worn out from free floating?" lol
-
Asking how many NOBL's to be worked on. One hour ahead of the timeline, so go to install all three NOBLs.
Scooter asks the spacewalkers.
"Gee I don't know Scooter" :)
"Ok, we're going to press" - Scooter.
-
Amazing. With Galveston Bay directly below, they can see Lake Michigan off in the distance. I'm waving, guys! Not to re-incite the LEO vs. interplanetary debate, but the small difference from ISS orbit is enlightening.
-
Good aliveness test on the FGS and they are going for all 3 NOBL's
-
NOBL 5 for standalong. 7 and 8 together via sequence.
-

Yeah, thats correct. I've been giving the elapsed time of the EVA against the plan, but the early start will allow the EVA to be extended.
-
Great view!
-
I assume they will declare full mission success now the FGS is complete too :-)
EDIT: They just have! - whoo!
-
This view really shows how much the EVA crew member can cause the arm to bounce around.
-
Full mission success when the NOBLs are installed. Absolutely awesome.
-
I think with these last tasks (when completed) STS-125 would have achieved 100% of everything they set out to do plus more. Correct me if I'm wrong?
-
Full mission success when the NOBLs are installed. Absolutely awesome.
The NOBL's were not in the full mission success list were they Chris?
-
I knew you'd ask that NYC ;)
-
Yeah, thats correct. I've been giving the elapsed time of the EVA against the plan, but the early start will allow the EVA to be extended.
As Dan Burbank said, the real limiter is the flight day timeline; the nominal EVA timeline had airlock repress at around 3 pm Eastern, so I'm assuming they could stay out until around then. (If necessary.)
-
Takin' pictures.
-

Low rank on the mission priority list I think.
-
Sorry for the long post, but:
As with every space shuttle flight, NASA has established a set of mission priorities and defined what is required for minimum and full mission success. The priorities, in order, are:
Three Rate Sensor Unit (gyroscope) removal and replacement
Wide Field Camera 3 installed in place of Wide Field Planetary Camera 2
Science Instrument Command & Data Handling System swap out
Cosmic Origins Spectrograph installation
Battery Module replacement installation (Bays 2 and 3)
STIS or ACS repair
Fine Guidance Sensor 2 removal and replacement
Remaining instrument repair (choice will be prioritized based on actual EVA progress)
New Outer Blanket Layer installation (Bays 8, 5 & 7)
Soft Capture Mechanism installation
Reboost Hubble Space Telescope altitude
Minimum Mission Success, i.e., what NASA would focus on if a problem prevents a full-duration mission, is defined as installation of:
Two Rate Sensor Units (four gyroscopes)
Wide Field Camera 3
Science Instrument Command & Data Handling system
Cosmic Origins Spectrograph
Bay 2 & 3 Battery Module replacements (six new batteries)
Full Mission Success is defined as installation of:
Three Rate Sensor Units (five gyroscopes)
Wide Field Camera 3
Science Instrument Command & Data Handling system
Cosmic Origins Spectrograph
Bay 2 & 3 Battery Module replacements (six new batteries)
Space Telescope Imaging Spectrograph repair, or Advanced Camera for Surveys repair
Fine Guidance Sensor 2
-
Still plenty of work to be done, though. Need to install the NOBL's, need to get the EVAs inside safely, need to get the aperture door open, need a successful HST deploy, and especially need to get the crew back home safely.
-
Slight nick on the RTV on the right thumb.
-
Sounds like there's a little wiggle room at the end. Ground says hard time for EVA cleanup to start is MET 23:45. That works out to about 2:47 pm Eastern...don't have the cleanup duration in front of me, but think it's a bit more than 15 minutes...
Correction (off by one) -- MET 23:45 would work out to 1:47 pm Eastern. (Not so much wiggle room, actually...)
-
Tracking a hard time to head into closeouts, to ensure they get to bed on time. Still enough to complete the NOBLs it would seem.
-
NOBL 5 is out and ready for installation. Have to write an article, so if we could have some of you updating/screenshoting while the regulars have vanished, it'd be appreciated.

Just checked some times.
MET is currently 22:21 and all three NOBL tasks nominally take 1:10.
Final closeout/ingress is 1:10 in duration (but they start that at 23:45 MET)
-
Nice shot above Atlantis.
-
Moving to cut two ground wires
-

Yeah, I screwed up; was off by one (updated earlier post).
-
Handing off NOBL while final preps for install are made
-
Peeling off Hubble's skin to get to the grounding strap.
-
Cutting Bay 5 MLI ground wires.
-
Bottom and top wires are cut, they are ready to start peeling.
As they start peeling, they are experiencing some debris.
-
Moving slowly down via RMS translation to continue removing insulation.
-
Looks like we have removal of a big piece of blanket, and a little piece hanging on to the bitter end.
-
Prepping to install NOBL 5.
-
Working at the bottom of the NOBL
-
Moving to work at the top now.
-
Now releasing three radiator cover latches.
-
Peeling off some sticky film from I believe the radiator cover.
"Try not to get stuck to it."
-
Passed into orbital night.
-
Wish I could post some better caps, but there's not a great view now that the sun has set.
EDIT: There we go.
-
Atlantis now passing over the ZOE, out of Ku coverage. Discussions ongoing with MCC on the next plan of attack with the remaining EVA time.
-
Next is NOBL 8 - this is nomially 45 minutes to do, and have to start clean-up in about 50 minutes.
-
Translating to the next worksite.
-
Can't believe I have to go back to watching normal TV tomorrow :(
-
If I may offer a description of what's going on, the translation around the worksite for NOBL 8 continues with repeated commands between the spacewalkers and RMS operator (Megan McArthur) for positioning.
It sounds now like they are getting to work with the PGT at the worksite.
-
After NOBL 8 do they have another one to attach?
-
It sounds now like they are getting to work with the PGT at the worksite.
For what PGT to this task? I thought there is no latches neither bolts..
and can someone explain me whats the point of using roll tool to install NOBL? I cant imagine it..
-
Starting to peel back the insulation. "This one's gonna be more interesting than five!"
Lost one piece of blanket, floating towards the cabin.
And Ku is back.
-
It sounds now like they are getting to work with the PGT at the worksite.
For what PGT to this task? I thought there is no latches neither bolts..
I don't know, I'm just going by what I heard. I heard them mention PGT and they were counting turns and talking about torque. More of an educated guess on my part. I have been known to make mistakes.

There was a wire tie-down repair to the MLI from an earlier service mission and it was wrapped around a J-bolt which John Grunsfeld needed to release in order remove the wire.
The NOBL panels have an adhesive layer on the back, and the roller is to ensure the panel sticks to the HST all over without any gaps.

5. Disengage Bay 8 bottom left J-bolt, 4-6 turns
-
Losing more pieces from this site than from Bay 5.
-
It sounds now like they are getting to work with the PGT at the worksite.
For what PGT to this task? I thought there is no latches neither bolts..
and can someone explain me whats the point of using roll tool to install NOBL? I cant imagine it..
There was a wire tie-down repair to the MLI from an earlier service mission and it was wrapped around a J-bolt which John Grunsfeld needed to release in order remove the wire.
Ahh.. many thank for clarification!

There ya go!
-
This blanket is shattering as they remove it. It's hard to get a good cap of the debris floating away, but there's a lot of it.
-
Now preparing to cut the grounding strap.
Top one is cut. Moving to bottom.
-
16. Cut Bay 8 door MLI ground wires (2)
Done!
-
Bottom strap done now. Atlantis will pass into orbital daylight soon.
-
Sounds like the old MLI removal is complete as they are talking about stowing the recovery bag.
-
Ku is back. Stowing the recovery bag with the MLI in it.
-
This will be the procedure for installation.
BAY 8 NOBL INSTALLATION (00:20)
1. Receive NOBL from FF EV; mnvr for installation
2. Install Bay 8 NOBL and integral vent plugs (4)
3. Connect NOBL ground cap on J-hook bolt
4. Release radiator cover latches (3)
5. Open radiator cover, re-engage latches (3)
6. Remove radiator protective film; stow in MLI
recovery bag
7. Release radiator latches (3)
8. Close NOBL radiator, engage latches (3)
9. Receive NOBL roller from FF EV
10. Roll surface of radiator slowly and deliberately:
- Starting from center of radiator, move roller
outbd in all directions, covering entire
surface of radiator
- Gently push on NOBL-ER frame to assess
adhesion
11. Transfer roller and cutters to FF EV
12. Stow MLI recovery bag onto MFR handle (upper
left)
-
Into final phase of NOBL 8 task, due to take 20mins, and final clean-up is meant to start no later than 25 mins from now.
-
Nice shot of Drew holding the NOBL and handing it off to John.
-
Shot from Drew's helmetcam of the NOBL install.
-
Wasn't there a third NOBL to attach?
-
Wasn't there a third NOBL to attach?
If they have time, NOBL 7.
-
Wasn't there a third NOBL to attach?
If they have time NOBL 7 will be installed.
-
-
It doesn't sound like they're going tobe able to get to it.
-
Wasn't there a third NOBL to attach?
NOBL 7, not sure if they are going to press for this as well.
-
Translating to work on the radiator cover.
-
It doesn't sound like they're going tobe able to get to it.
Not unless they extend the EVA. Doesn't sound like they want to do that right now, though.
-
Removing the film from the cover. "Definitely sticky!"
-
Closing radiator.
-
Getting out the roller.
-
"Rollin, Rollin, Rollin!!!" I think he's dating himself there.
-
"Rollin', rollin', rollin'! Everybody sing along!" :D
-
NOBL 7 showing as 20 mins task but seems way simpler than the other 2, no removal of existing layer no radiator to cover and stick down.
Singing Rawhide up there now, don't give up the day job (but who would?)
-
"Rollin, Rollin, Rollin!!!" I think he's dating himself there.
heh, I was humming that to myself!
-
Getting out the roller.
"Rolling, rolling, rolling. Come on everybody.." :)
Great work Nick. Finalizing the article and will be back with you all shortly.
-
Nice view of the spacewalkers.
-
Go for 7
-
Go for NOBL 7!

BAY 7 NOBL RETRIEVAL & INSTALLATION (00:20)
1. Mnvr to MINC
2. Boot plate and MFR stanchion as req’d
3. Receive NOBL 7 from FF EV
4. Mnvr to Bay 7
5. Install Bay 7 NOBL and integral vent plugs (4)
6. Connect NOBL ground cap on J-hook bolt
7. Very high five!!
-
Going for NOBL 7...awesome!!
-
2 of 3 (highest priority) NOBLs are installed. EVA will be extended to install NOBL 7 as well.
-
I love this shot from the RMS elbow cam. Looking at a small piece of material on the PLB seal.
-
Found a bit of latex glove on the PLB seal, talking now.
-
MCC discussing whether to remove the material. Concern would be prevention of the PLBD from sealing upon closure.
Removing the last NOBL from the MULE.
-
Looks like they found what they say looks like a piece of latex glove on the payload bay sill. No plan to retrieve it.
-
To be clear, I have circled the material in question.
-
Translating to Bay 7 with the NOBL now.
-
Final panel is being moved into position.
-
I'm loving these shots from the RMS elbow!
-
Working on the bottom of the NOBL now.
-
last vent plug being installed now
just the ground cap on the J-Hook to go
-
near done.....must nearly be time for them to do for a really cheesy photo
-
Overall view.
-
Dr. Grusfeld taking one last picture!
-
And out comes the camera
-
Has there been any word on the new battery? Is it alive?
-
John getting out the camera to take a couple pictures. (How long before they hit L2? ;))
-
Now onto PLB cleanup. Glove inspections first.
"Covered in gold foil."
-
"A NOBL cause!" Now that's damned funny.
-
"A NOBL cause" from John.
"John, if you're done monkeying around with the telescope, I'll bring you back" - Megan.
Loving the banter.
-
Now both are moving back to the airlock to prepare the PLB for closure and entry.
-
John "Drew, ...a noble cause we are serving"
groan...
-
Self portrait?
-
Self portrait?
I think that's what they're going for.
"This is a very beautiful spaceship"
-
-
I wish I could post some screen shots. A great view of the orbitor.
-
I wonder if Mass and Bueno are thinking "Man, those guys get all the easy stuff..."
-
"This is a very beautiful spaceship"
I agree!
-
"A very beautiful spaceship" - nicely said sir!
-
Great views of the orbiter. Hope we see some of the photos he's taken.
What an amazing mission. They've accomplished every single task!
Keith
-
They may have a very beautiful spaceship, but I think we have an even more beautiful planet.
-
-
Working next at the airlock.
-
-
Nice view of the OBSS on the starboard PLB sill.
-
Tool inventory
-
"A very beautiful spaceship" - nicely said sir!
Concur , Chris!!! She's amazing!
-
Talking with MCC about bits of MLI on gloves. Making sure that it won't get loose in the crew cabin after ingress.
-
Moving on to tool inventory now.
-
Money shot
-
-
Still doing tool inventory
-
Inventory complete and looks good.
-
Payload bay cleanup is next. This will include stowing the foot restraint used on the end of the RMS as well as removing the BAPS support post on the FSS underneath Hubble.
-
It will for sure be very hard for crew to relase Hubble and get back to the Earth tomorrow. In some way it will be like saying goodbye to an old friend for the last time :-[
-
Both spacewalkers are out of this view, but you can see the darkness of impending orbital night out behind Atlantis.
-
Latest article: http://www.nasaspaceflight.com/2009/05/final-spacewalk-marks-full-mission-success-for-sts-125-eva/
-
Now in the process of stowing the foot restraint.
-
-
Wow. So this is it. The last time we work on the Hubble. Kinda sad.
-
-
Orbital sunset.
-
Telescope activation underway. This is being worked by Scooter. Deploy of the HGAs will occur and HST will be rotated back to its initial position. After this, the Solar Arrays will be slewed to their 90 degree position.
-
MFR clear.

What is hiddin under BAPS phrase?

What is hiddin under BAPS phrase?
If you mean what does BAPS stand for, it is Berthing And Positioning System.

Currently out of Ku over the ZOE. Spacewalkers are still working on the cleanup of the payload bay.
-
It was just mentioned that they're getting ready for HST antenna(?) re-deploy. I thought they did that before grappling, so if that's the case, wouldn't they want to wait until tomorrow until the HST is released so that re-deployed antennas don't hit something on the orbiter upon HST's release?

Ahh ok.. thanks!
-
whoops! kicked the LGA end cap
-
Sounds like they've accidentally hit part of a low gain antenna on Hubble. No picture of that right now.
-
How bad could that be?
-
John really bummed out about accidentally kicking the low gain antenna.
...and he comments that this will show as his "highest heart rate"...
-
There's Ku back, so let's see what turns up.
-
John's ending comments about Hubble
as part of
Humanities quest for knowledge
good words!
...unlock further secrets of the Universe.
-
-
Amazin words..
-
Hope someone recorded that (John 44?)
Some paraphrasing:
"This has been a really tremendous adventure a very challenging mission. This is not just a satellite, but human quest for knowledge. A tour de force of tools and ingenuity. The only way to find out what is possible is to do the impossible. Being on a marvellous spaceship like Atlantis shows us what is possible, and maybe we can use the experience on things like solving the world's energy demands. We wish Hubble well."

Concur. A whole bunch of great words. Too many to list, but a great closeout speech for the whole team on doing the impossible.
-
Sorry, had to run away to answer the phone.
-
I think I am going to save Mr. Grunsfeld's quote. Very nice.
-
just prior to ingress
-
Looking at putting the LGA cap back on
-
What the VFA, that has been asked about a couple of times (checked acronyms)?
-
LGA is still operational, but the cap might provide some extra thermal margin. Ground still discussing.
Ground gives a go to put the cap back on.
-
...a great closeout speech for the whole team on doing the impossible.
I'm sure I thought, and am pretty sure I posted here when I read the mission plan, that this was totally nuts and they'd never get all this stuff done. I'm again impressed by the ability of the entire NASA team to pull off what sounded like an impossible task.
-
EV-1 going back on the arm, EV-2 translating back.
-
ground deciding that a cover is to be put on the LGA (still functioning) end to ensure better thermal protection
-
I've copied the LGA diagram from the HST Cargo systems manual from L2. I'll post it here if Chris has no problem with it.

That's about right. I had every hope they could get ACS fixed, but was resigned to the fact from SM4_Engineer that it wasn't going to happen. I am so glad that they got everything done, including ACS and STIS (all those screws!). NASA has come through again. They truly did the impossible on this mission, and it sounds like they are putting the star back onto the tip of the sending unit to 'cap off' a great mission :)
-
Here are the pictures from the HST cargo systems manual available on L2. The first shows the protective cover, the second is a diagram of the LGA ORU. If anyone more familiar with these could shed some light, that'd be great. Chris if you are against these being in the public thread, feel free to delete this post.

cover replaced, pip pin in (Johns helm cam)

Cover reinstalled.

My goodness, what I'd to to be in their place right now!

John "Sorry Mr. Hubble"
[edit]... I think the "Hubble gremlins" have a weird sense of humor and wanted one last application of "Murphy's Law".
I should note for those not hearing audio, that Houston has assured John et al that the HST team has verified that the low gain antenna is working fine in receive, and they expect no problem with it.
-
Heading back to the airlock.
-
"electronic brain surgery" how true
-
"Take a moment, this is our last spacewalk on Hubble."
"Drew, you're an incredible spacewalking partner. Thanks again."
Going to take a picture.

Goodbye Hubble

Hmm, wrong hatch:
-
John going in:
-
"..just hang out there.."

-
Sounds to me like they are enjoying the spacewalk experience so much that they don't want to give up that one last look at the planet. I can't say I blame them! 8)

Who switches from camera to camera, someone on the Orbiter, or someone in Houston?
-
Ready for free drift
-
FANTASTIC bunch of EVAs & one heck of a mission.
Everyone, thanks for posting all the wonderful images and the live coverage. It was great following along.
Laters. :)
-
Who switches from camera to camera, someone on the Orbiter, or someone in Houston?
Those aboard the shuttle can switch at will, but I believe PAO shows us what they would like at any given time. So the answer I believe is both, but PAO determines which view we look at.
-
Standing by to watch HGA deploy.
-
Wonderful EVAs.. wanna rly thank to all people here who provide great coverages. You do amazing job guys, undeniable amazing!
-
HGA deploy is underway.
-
Is it just me, or does it seem like we don't hear much of anything from Greg Johnson the last few days? Is he still on board?
-

No he decided to return to Earth after they captured Hubble on FD3. He said it was too cramped in the crew cabin or something like that. ;)
-
HGA deploy continuing. Airlock is repressurizing. EVA clocked at 7:02 in duration.
-

Hiding in a middeck locker maybe? ;) Which old mission was it when they filmed one of the crew hiding in a locker? Really funny video if anyone can find it.
Betcha Philip will know ;)
-
Now preparing to view the dish gimbal.
-
This whole mission, 5 EVAs, all the objectives accomplished, was great. The whole team did just what
they set out to do!!
-
Hiding in a middeck locker maybe? ;) Which old mission was it when they filmed one of the crew hiding in a locker? Really funny video if anyone can find it.
They stowed and unstowed Joe Allen from a middeck locker on STS-51A.

-
HGA dish gimbal underway. Very noticeable in the right picture.
-
Handing over to Orbit 2 team. Saying now that LGA looks like it will be okay.
-
3 minutes for an answer.
It was shown many times on CNN; easy to remember when you're 15 and it's only the 14th shuttle flight.
For video, I'd check the crew's mission presentation (Google Video?).

Stowage of the crew member is at 6:43
Getting back on track: did anyone catch the EVA total hours for Hubble and the individual crew (posting from work)?
-
HST being rotated...I missed a part of the conversation last night talking about sleep shifting, but they're talking about it now...sounds like they are setting up to pull in de-orbit opportunities one rev earlier, which would require the crew to get up one rev earlier. Still under discussion.
-
And Hubble is being rotated back to its original position.
-
Someone asked the question before and I am not sure if it was answered. When the orbitor approached the HST, the HGA were retracted. When they release the HST they be extended. Why, is it because of the possibility of hitting them on approach of the orbitor?
-
...?
anybody else understand the comment just now (I think by Scooter)
that we "are ready for the early de-orbit" when talking to Houston?
[edit] followed by comments concerning this evenings PMC "which will have a couple extra people involved", and "imaging capability"
...just curious
-
-V3 side now rotated in front. Rotation is complete.

Would have said this at the end of the EVA, but a work issue kept me busy. It has been a pleasure following these historic spacewalks with everyone on the list, and a big thanks to Nick, Ron, Chris, and all the other folks who contributed and allowed me to follow along when reality interfered with my viewing. Thanks again!

Almost to the 90 degree position.

A Low pressure system just west of me at 17.5N, 75.8W has been designated an "Invest" by the NHC and the computer models indicate probability of it moving slowly North toward Florida, with a possibility of developing into a Sub Tropical System bringing heavy rain to Florida. We have had heavy "tropical" rain here today in the Turks and Caicos.
This weather will quite likely impact the plan to land at KSC, later this week.

There is a clearance issue; one of the HGAs is in between the two grapple fixtures and the RMS would have to avoid it on the way in if it were not retracted.
-
MSB coming up shortly. I'll be happy to transcribe it. It'll be nice to see how happy the Hubble guys are today!

I haven't been able to post during this mission, but I want to take the time and thank everyone who did! Especially Chris, Ron, Kel, Nick and all the other guys doing so damn good coverage!!!
And I want to express my deepest respect for the Astros up there and all the folks down on the ground who made this mission the huge success it is! For the ones up there: come home safely!
Now I can sit here after a damn stressfull week, listen to some great jazz, enjoying some great wine and smile about this truly historic mission... :)

Same here! I have been following this mission whenever I could (I've have lots of exams lately), and I'd like to thank everyone. This has been a fantastic mission!! :)
-
Tony C: Crew really excited about today's EVA. Got ahead in timeline, so we were able to complete all EVA objectives. Couple of hiccups again, crew reacted quickly. Tremendous team effort. HST deploy tomorrow. Both sad and happy day. Last planned EVA out of shuttle airlock. This is really over, don't know what to say but congratulate each other. Will be setting up suits for Mike and Mike for contingencies.
-

Yes, as long as the weather is acceptable there. But there's probably going to be somewhat of a wait and see for the next few days.
-
Tomas: 7:02 EVA today, 36hr 56min for all five together. Completed all objectives, and all three NOBLs. Wanted to thank all excellent teams we worked with. Priviledge to work this mission.
-
Jon: Hubble returned to flagship status. Full arsenal of instruments and tools for the next several years. Want to thank everyone involved in this endeavour (or Atlantis;)). Kudos to everyone who got shuttle ready, all the crews at all centres that made this a success. It is bittersweet. We have a saying, "Science never sleeps". We can't wait to use hubble for its intended purpose.
-
Preston: Feels like it must feel to win Superbowl (American football). Working in space is difficult, and it is fine line between things that look easy and things that are impossible. Thanks to the crew, they never gave up. The customer's expectations have been exceeded on this mission. Coming into this mission we had 18 perfect EVAs. Team on orbit powered through their EVAs and we accomplished more than we hoped. Takes a lot to put a mission like this together. Want to thank everybody. Looking forward to deploy and use of new Hubble instruments.
-
Questions.
Q: Review commissioning period, when can observations with Hubble start?
A: Called SMOV (servicing mission observatory verification). About 4 months of intense activity to focus, checkout and calibrate instruments. Aiming for early September this year. Not much real science for the next several weeks. After that we will start worthwhile observations.
-
Q: Characterize teams waiting to pursue investigations with Hubble
A: Excitement for new instruments is high. 8 or 9 hundred proposals come in from around the world. 200 or so are selected. You need to be better than top quartile to use Hubble.
-
Q: Go over Orbit adjust plan.
A: Larger concern for MMOD. Go down to perigee of 160, closer to station flight. Looking at landing 1 rev early. Trying to avoid sea breeze effect.
-
Q: What is LGA used for?
A: Two LGAs. One on top, one on bottom. Together they provide hemispherical coverage. Can only use one at a time. LGAs only used during emergency periods when do not have HGA access. Placed cover over top, it is RF transparent. Always protected for a rapid deploy, so this cover is good to go, able to fly away with it on. No problem.
-
Q: Over last 19 years, you've learned a lot about maintaining this with human presence, what lessons have you learned?
A: One thing that we learned is the tremendous benefit of NBL to rehearse EVAs. Learned value of specialized tools that we built for spacewalker efficiency. PGT was one of those, it gives big savings in spacewalker energy. Learned how to choreograph EVAs well. Learned a lot on SM1. Musgrave understood importance of conserving energy, making every movement count. Also go through lessons learned after each mission. Good documentation, learned from mistakes.
-
From MSB:
Last planned EVA out of shuttle airlock. A lot of people don't realize that.
So sad. I hate to see the the shuttle go. I know it's old and tired, but man, that vehicle has been amazing for MSF. I can't help but be underwhelmed by the thought of flying via Constellation. Ares and Orion are evolutionary. The Shuttle was revolutionary! Sad to see the end...
-
Q: How much of this mission could have been done by a robot.
A: Robots would have been hard pressed to do what humans just did. Like wrenching off that handle. Adaptability and speed of humans to react to things as they happen are important. Interfaces need to built with robots in mind. Hubble was not designed like that. Changing out instruments with robots made management nervous, as did instrument repair. It was potentially feasible, but not demonstrated yet. Better if Hubble had been designed to be serviced by robots.
-
Q: Capture mechanism for deorbit, how is that planning going?
A: SCM (Soft capture mechanism) uses a system known as LIDS (low impact docking system) intended for future NASA missions. Easy to RNDZ and dock with Hubble in future. ELV with propulsion module to dock with SCM. We have a lot of time to decide, as decay will take to about 2020.
-
Q: Fly around of Hubble?
A: Not gonna happen.
-
Q: How far along will the Mikes be ready for EVA tomorrow?
A: Up to EMU donning.
-
Q: When will STS-400 crew be released?
A: After late inspection imagery review as far as I know.
-
Q: Any plans to work on NICMOS during commissioning?
A: We will work on it as time permits, but commissioning is priority.
-
Q: Last time that humans will see Hubble, what will your team be feeling? Do you operate it differently knowing that this is the last mission to HST?
A: Bittersweet feelings, and sad that this is the last time we will see it. Happy for 20 years of service, looking forward to at least another 5. We learned a lot over 19 years on how to operate. When we were unsure of SM4, we went into life extension program, made changes to operation to maximize lifetime, so we can use those techniques.

Q: Last spacewalk out of shuttle airlock. Last satellite servicing. Feelings on that milestone?
A: The station is our future. Sad moment, but a great moment. We put Hubble in a great posture. Continue to press on with station.
-
Q: Telescope returned to flagship status. Fair to say that Hubble is brand new compared to what it was in 1990? Anything that is original still on Hubble?
A: Still a lot of original equipment. HGA gimbals are still originals. When HGAs stop tracking, it's gonna be difficult to get data down. Knock on wood. Original data management unit, several hundred components that are original. Solar arrays, gyros are new. Great job in taking care of known wear out items. Tape recorders were state of the art when launched. Two of those replaced with Solid State recorders. Arrays are now smaller in size, less ballistic profile, more power. Like a free reboost. Last group of gyros removed had some early improvements, so they lasted pretty long.
Then we have instruments themselves. They are orders of magnitude more powerful. It is more capable than Hubble of 1990.
-
Q: Status of instrument aliveness?
A: WFC-3 is good, COS is good, ACS is good. STIS aliveness is good, minor mistakes in functional checkout plan, had to restart, still working through. Trying to restore mechanism power. That has been restored. No reason to believe it won't pass functional.
-
Q: How much more powerful is Hubble now that when it was launched and first serviced in '93?
A: Several parameters you can look at. Data volume has increased about 30 times. Wavelength coverage can now look at near infrared, we have full spectral capability. Instruments are far more sensitive. Next gen instruments do order of magnitude better than originals. WFC-3 sensitivity is exquisite.
-
Q: Five years from now, when you look back at what has been learned what will you expect to see?
A: Expect to be able to do a lot more with dark energy. Expect to see assembly of galaxies earlier than before. With wide field capability we can do surveys across the sky, can look at stellar populations as they evolve over time. Can look at star formation, and planetary systems. Want to analyze atmospheres of extrasolar planets. Balck holes, globular clusters. Hubble has shown us it is things you can't anticipate that yield the best results.
-
Q: What are you going to look at first?
A: We are NOT going to look at the bright earth. Don't have specific list of targets yet. Observing point sources like stars is always one of the first things we do. This is used to calibrate optical distortions. This is done as part of SMOV. Common in the past to look at globular clusters and things first.

I haven't been able to post during this mission
Same here! I have been following this mission whenever I could (I've have lots of exams lately), and I'd like to thank everyone. This has been a fantastic mission!! :)
I'd like to second that (or third, I'm not really sure (http://nsf.breakie.com/Smileys/default/cheesy.gif)) Lots of work and exams coming up in June, so didn't really have time to watch all the EVAs, not even one of them fully. That, combined with the special character of this mission, has made your coverage absolutely priceless, and very much appreciated. To "rewatch" the EVAs great moments, with unique pictures, and with your great comments and quoting, was almost as good as watching it live. The only drawback is that I couldn't almost contribute, but well...
A huge 'thank you' to the whole NSF community for allowing us to have this amazing corner of space goodness in the Internet.
STS-125 is being an absolutely jaw-dropping mission, looking forward to the grand finale. Kind of sad to think of this as being the last forseeable crewed mission to an uncrewed satellite. Also the last one to get as far away from the Earth for the next 10 years at least... only 600km, but almost twice what is usual for ISS or space stations.

Well dont worry the best is yet to come, in Imax 3D (when can I prepay for the tickets already!)

Mike Massimino interrogates the rest of the crew again on the HD downlink coming down now. In an entertaining way. :)
-
Massimino and his interviews are great :D
"What was the most nail-biting moment for you? (talking to the CDR)"
"Rendezvous..."
"..."
---loud laughs--- ;)
"What did you like most about the EVAs?"
"You breaking that bolt."
"Oh, I did it when I knew the ground didn't have video, so that I could get it over with"
"What do we do now the spacewalks are over?"
"Well, we have late inspection... were you part of this team?"
"Oh, I am... but then we have a day off!"
-
The bit after that with Scott Altman interviewing Mike Massimino was also good. Now running some more video.

This transcript from the CBS e-mail is funny:
The antenna incident occurred near the end of today's spacewalk as Grunsfeld was rigging Hubble's support platform for the telescope's deployment Tuesday.
"One last handshake with Mr. Hubble from me," Grunsfeld called at 2:27 p.m., removing a support post from the base of the telescope. "OK, I'm off the telescope."
"Copy, off the telescope," Mike Massimino said from the flight deck.
A few moments later, Grunsfeld apparently bumped the low-gain antenna.
"Low gain ant... hold, John, stop, stop, stop, stop, stop," Michael Good radioed from inside Atlantis as Grunsfeld floating near the base of the telescope.
"Thank you."
"OK. We liberated a small piece of something off the end of that."
"Yep, we did," someone said.
"You see where it went?"
"It's under the telescope, passing underneath," Good said. "OK, it's coming back down into the payload bay now."
"You see where?"
"Yeah, I can see it. It's right by the BAPS post. You can probably even get it."
"I don't think it's an issue," astronaut Michael Massimino said.
"Yep, I think we ought to get it," Grunsfeld disagreed.
"OK."
"We've got eyes on it," someone said.
"Let me go look at the antenna..." Grunsfeld said.
"It looks like a little piece of tape..."
"Ahhhh..." Grunsfeld groaned. "Is it a little piece of tape?"
"Yeah."
"I've got it," Feustel said.
"Oh no, I hope the antenna's OK," Grunsfeld said. "Oh, I feel terrible."
"You hit the low gain?" Massimino asked.
"I tapped the low gain antenna with my foot," Grunsfeld said. "Ahh...."
"There are two of them," Massimino said in an effort to cheer up his crewmate.
"No, Houston, do you have a picture of this?" Grunsfeld asked.
"Atlantis, Houston, we can't see you right now," Dan Burbank called from mission control.
"OK. I'm sick," Grunsfeld said. "It kind of knocked off the end cap."
-
Perhaps I missed this, but since it seemed so simple to replace the cap on the LGA, why didn't John just replace it when it was disturbed?

Q: Status of instrument aliveness?
A: WFC-3 is good, COS is good, ACS is good. STIS aliveness is good, minor mistakes in functional checkout plan, had to restart, still working through. Trying to restore mechanism power. That has been restored. No reason to believe it won't pass functional.
I was wondering about the repeat functional test of STIS after it safed itself yesterday....guess it's still in work.

Yeah, that was the gist of the answer during the MSB. STIS is alive, but mistakes were made during the functional, and they've had to repeat several of the procedures. That is still ongoing. Preston has faith that it will all work in the end though.

doesnt sound good for PAO to be chowing down while talking.
-
Say cheese!
wow...that picture gave me goosebumps, as I read through this thread--kinda like the last day of your senior year in high school, knowing its over, and you're leaving your friends--you know there is exciting stuff coming up in the future, but its bittersweet anyway.
thanks everybody for the postings, it has been great to catch up, and being able to get more details on the events as they happen. NSF is a fantastic resource! Also congrats to the STS-125 crew--great job!

Replaced 19 year old batteries.
Replaced FGS
Replaced insulation.
Every task got done. Aliveness and functional tests in work. All aliveness tests OK. Functional test of batteries in progress. Functional test of FGS to come.
Charging of the new batteries overnight.
After release tomorrow many activation, configuration and testing tasks to do. Will be 5-6 months before the telescope is fully commissioned and back to normal operation.
Expect first new images to be released in September
General euphoria in STOCC.
-
Batteries and FGS have now passed aliveness AND functional tests so that makes complete success for the mission so far. Just remains to chuck it back into space and have it do its thing. ;)

Q: Last spacewalk out of shuttle airlock. Last satellite servicing. Feelings on that milestone?
That's something I never fully realized either until I started reading the last few posts. That is a sad moment. Well, what better way to end it than on a high note! :)

THAT'S what it was...
At first when I heard that, I thought he hurt himself, but then dismissed it as me hearing something...
I can totally imagine how he must have felt, doing all that work and then breaking something. I'm glad he had a buddy there to cheer him up, and MCC saying it all seems to be working okay for receive, and no reason why it wouldn't in transmit. That's what I call family. :)

Glad to see that you had as much trouble grabbing a good screenshot of him as I did (over in the HD thread (http://forum.nasaspaceflight.com/index.php?topic=11551.msg403061#msg403061)). That guy is blinking constantly :)
Incredible mission, great coverage here at NSF, I'm exhausted just from keeping up :/ ... And Real Work has piled up to stratospheric heights during the past 8 days.
-
Thanks for the weekend coverage everyone... back now to civilization and high speed internent. Here are a few live pictures coming in from the shuttle payload bay... just some nice ones of the bay and Hubble to end the day... The second one I believe is where the little bit of debris was located...
-
coming up from underneath hubble
-
Here is the low gain antenna that I believe was the one that had the cover knocked off... all back in place
-
Adding my thanks for the coverage of these historic EVA's.
Excellent job guys.
Excellent site Chris.
-
underneath hubble...
-
Simply Way cool shots... now heading into orbital night..
-
The glove debris - Extreme closeup and larger picture to give context of where it is..
-
Great coverage, thanks everybody!
And of course a great mission, but a bit bittersweet :cry:
