FD3:
• HST Rendezvous/Grapple/Berth
– Grapple: May 13 (Wed), 133/16:54 (12:54 EDT)
• HST Umbilical Mate (Orbiter power)
• HST RMS EE Survey
• SA Slew to 0 Deg (prep for EVA 1)
• EVA 1 Tool Config/ EVA 1 Procedure review
Please note, this is interactive, but all posts need to be on topic. If you post images, no more than two per post.
Updated timelines via a MMT presentation this evening:
-
The "big picture" plan
-
About 37 min away from crew wake at 4:01 CDT
Hubble grapple due at 11:54
-
Countdown timers in MCC
-
PAO guy is getting very excited about crew wake up. Treating it like a launch countdown :D
-
Wakeup tune Upside Down by Jack Johnson for Megan Macarthur
-
Orbit 3 team handing over to Orbit 1 team. Dan Burbank is Orbit 1 CAPCOM taking over from Shannon Lucid
-
Here's one showing hubble and shuttle. Not very high resolution
-
Hubble high gain antennas have been retracted, aperture door has been closed to protect the mirrors and telescope has been maneuvered into grapple attitude.
-
And we have FD3 Execute Package available:
http://www.nasa.gov/pdf/346083main_FD03.pdf
-
TI burn at 9:41 CDT
-
Time to go visit ol' Mr. Hubble The Space Telescope!
This movie has nothing to do with 125, but it is nonetheless interesting as we see rendezvous ops with Scott Altman and his crew from 109.
http://www.youtube.com/watch?v=cSiVUTeJVBA (http://www.youtube.com/watch?v=cSiVUTeJVBA)
Keep the great updates and screenshots coming! :)
-
First image from orbit today.
-
Did I just see something fly past the orbiter on NTV?!
A few seconds after the video started something (apparently) flew right to left very rapidly (few frames only)
image artifact?
-
-
-
The playing field ready for action. And I had the third one showing the location of the goal posts but I see that's been posted above. :-)
-
Water dump is complete.
-
Atlantis is currently around 1200 miles behind Hubble
-
Summary timelines for today
-
Might have been reported already, but the crew was recently told that the HST high gain antennas have been retracted for capture.
Scott Altman got concurrence to start Group B power up a little early when they get closer to that in the timeline.
Hefty NH burn coming up after that: delta-V of 308 fps! Burn time is 198 seconds; magnitudes are up there with some de-orbit burns.
(Prelim PAD for that is in the Execute Package.)
-
Page 21 of the Execute Package has some relative motion diagrams to help visualise what is going on with the NH and TI burns
-
Atlantis has been asked to deselect IMU 3 with an item 9, don't know what that means, but then given go ahead to proceed with orbit ops.
I wouldn't mind a close up view of that right hand screen instead of the usual three axis view.
-
Atlantis now has a good IMU align and crew given go ahead to reselect IMU 3.
-
I wouldn't mind a close up view of that right hand screen instead of the usual three axis view.
Yep, that's very interesting!
FD3 article about one hour away, rounding up a ton of info, but avoiding getting wordy as there's no real issues being worked and MER are still only on three "Funnies" (which is very low/good!)
-
I wouldn't mind a close up view of that right hand screen instead of the usual three axis view.
They show it occasionally during rendezvous ops, and all the missions now have a rendezvous in them.
-
Orbital dawn. Very quick at this altitude.
-
Atlantis has been asked to deselect IMU 3 with an item 9, don't know what that means
GNC SPEC 21 IMU Alignment, have marked item 9 with crudely drawn red box. Notice how it's under the "3" column for IMU 3. Des means Deselect.
-
Thank you sir.
-
There's really not a lot happening right now but here is an "arty crafty" image to go on with. Promise its my last cargo bay image until something changes ;)
-
Chris,
I think the HST grapple date and time in the top post are incorrect, it should read
"May 13 (Wed), 133/16:55 GMT (12:55 EDT)."
I know you are very busy, but if you got a minute ... People might look there first.
Thanks for your work, BTW!

Thanks much :)
And thanks for the correction to the opening post. What I've done there is copy the text info from the SSP FRR overview presentation (which was when STS-125 was a May 12 launch). Corrected it.
The screenshot is from a MMT overview presentation last night, so that's correct at least :)
-
The countdown clocks. Getting closer :)
-
Actually it's 133/16:54 now, according to PAO and NTV-schedule. Sorry!
-
Copy the 54 mins past the hour, thanks!

Updates to NH PAD
Weight 252833
TIG 01/18:15:19.8
and other deltas to attitudes
Max TIG slip is only 45 sec
-
Talking about NC4 burn:
-
used I14R10's images to make this:
-
targets loaded for nh burn
-
maneuver to get into position for NH burn underway
-
Anyone know what the purpose of the attitude "BIAS -YLV -ZVV" that they were just in, ie, why that attitude instead of the normal "-ZLV -XVV"?
-
KU failed hot test, but should not be an issue
-
Interesting view of the rendezvous profile on the screen, you can tell they are not going to station!
-
Want elbow camera on tail for burn, that would make a good video...
-
Camera to view the OMS Burn? Oooo, that would be cool.
-
Want elbow camera on tail for burn, that would make a good video...
Helps if it's night-side after ignition.
-
right now all I see is black with some occasional flashes.
-
minute and a half for burn, good config for the burn
-
Good config for the NH burn, one minute to go.
-
-
POW! That's very cool!
-
-
Thought it wold be more symmetrical (ie, both engines burning.)... Is it perspective or is it only one engine firing?
-

Perspective. About a minute remaining in the burn.
-
This will probably be the largest single burn (excluding deorbits) for the remainder of the program.
-
Good burn, no trim required.

Nice words for Atlantis and the OPF guys from the commander after hearing they don't need the NC4 burn (a first): "good to know how well Atlantis is doing and a testiment to the guys that got her ready".
-
next up is to configure the star trackers
-
-
Under 280,000 feet and tracking the dotted line perfectly
-
in 15 minutes, solar arrays will be repositioned on hubble for rendezvous.
-
Tool prep continues and all the PGT's have been checked and settings confirmed.
-
Configuring Atlantis for vernier control
-
I guess we'll get the first glimpse of Hubble at about 100,000 feet or so.
-
Did Kyle just say Atlantis is closing in on the ISS? ;) (Totally forgivable - it's a tough gig commentating for hours on end during a mission).

Better than when he called Atlantis columbia....
-
-
Yep, he's slipped that one in a few times during the morning. Been saying it so for so many missions I guess.
Meanwhile closure rate has dropped to about zero as Atlantis reaches Apogee.
-
When will Hubble become visible?

The camera on the FSS used to assist in berthing the telescope is the same unit that provided views of Columbia's cockpit during STS 1

The yellow is actual track, the dotted line is required track.

The solid yellow curve is the history of the orbiter's position relative to Hubble, computed using the onboard state vectors.
The dotted yellow curve is the prediction of same, at five minute intervals.

Not required, predicted. The dotted line assumes coasting flight, no future burns.

I thought we got a third plot where there was a deviation between predicted and required. Could easily be wrong though.

Next up small correction burn

ggo for nc burn

Heh, Dan Burbank was out of the room for a moment, so Tony Ceccacci called that up to the crew.
-
213000 feet out, closing in at roughly 69 fps

Here's the rendezvous profile from NC-4 (was not required) to MC-4. Small burn just made was NCC.

The image above makes it pretty clear that I am (wrong that is) :P
-
We are less than 3hrs from scheduled HST capture
-
-
That's the one I was thinking of with required and predicted paths.
-
You can see in the top left corner the graphic above the path Atlantis would take without burns - the dotted yellow line. At the apogee of that orbit, there will be another burn to continue on the yellow path. I believe the burn at apogee (the top of the little loop) is the TI burn
Very cool to see orbital mechanics in action
-
Crew was given a go for TI prior to the earlier period of ratty comm (although sounds like we're in another one)...TI PAD updates called up to the crew after that...
-
-
-
-
-
5 mins to Ti burn.
12s, left OMS only, 9.8ft/s
-
Good burn, no trim req'd
-
This is the post Ti burn profile up to MC4 with PET timings (begins at Ti burn).

There are multiple displays that get put on the TV. The one you're referring to (RPOP) doesn't have the required trajectory, but one of the others (the FDO display with the orbiter attitude window on it) does have required trajectory. My bad.
-
-
Anyone have any info on this 'BSA" issue they are talking about?
-
They are discussing problems with a box called the Bit Sync Assembly (BSA) which recovers data waveforms transmitted by RF from the Hubble telescope before passing the data stream on to the Orbiter systems.
They are having problems establishing a "lock" with the Hubble at present (they thought it might have been a range issue before when they tried).
Picture of the box attached.
-
Have looked around for FD2 highlights, but no joy. Can anyone point me in the right direction? Thanks. (This rendezvous is so exciting, I can hardly stay in my seat; your coverage and commentary is exqusite.)

"The Bit Sync Assembly (BSA), facilitates clean telemetry between HST and the Orbiter S-band communications system by processing the data stream through a digital bit synchronizer board"
-
"BSA is physically warm" sounds like an unsettling "datapoint" (BSA? DSA? wasn't sure)

I think I was the one who got it wrong but its so late here I turned into a pumpkin about an hour and a half ago so what the heck.
Crew is still having trouble with the BSA.

Thanks Andrew! Just read through the presentation, and I did not see anything that could be considered a show stopper for today.
-
How long we will be still out of KU? And in what time there are scheduled "breaks" in signal?
-
According to the L2 presentation, the BSA should have a nominal power draw of only something like 16 watts. But I don't see a fan - passive cooling in zero Gee must be fun engineering...
-
Just passed the word that they will bypass the BSA.
-
MCC has decided to abandon troubleshooting on the BSA and bypass it in the communications link to the telescope.
-
I think that they should have two BSAs on board
EDIT: PAO just confirmed
-
Can I get a range update? I'm on a train so can't watch the stream.
-

PAO just mentioned they do. If they swap out, it will be post rendezvous.

God, I love how that BSA front panel has a couple 4-light binary number readouts. That engineer must have learned on the Altair.... :)
-
Range 6900 feet, closing at ~10fps
-
Ku in radar mode.
-
-
Hubble tallyho!
-
Go to burn MC3
-
Tallyho!!!!!!!!
ETA: Solar arrays in proper attitude for capture.
-
Too bad no Ku for downlink, guess we wont get it until after rendezvous
-
Along with the tallyho also confirmation that the arrays are feathered for capture.
-
Go to burn MC3
A whopping 0.4fps.
-
2 second burn.
Good MC3 no trim req'd.
-
Have they turned off the Ku antenne? And why?
-
-
4000 feet r, r dot 6 fps
-
Ku is in radar mode for rendezvous
-
Have they turned off the Ku antenne? And why?
Not turned off, just in a different mode. It's being used for rendezvous radar vice comms.
-
-
Have they turned off the Ku antenne? And why?
This is often asked so I'll explain and is often a point of confusion.
The Ku antenna is also the rendezvous radar. It can't provide comms and work as the rendezvous radar at the same time. Currently it's tracking HST providing range, angles and rate information.
-
thanks for good answers :)
-

-
10 second MC4 burn in 1:20
I think he said 2.2fps via RCS jets.
-
good burn no trim
-
Can we get S-band in this mode?
-
OK, following the MC4 burn we are now into the terminal phase and flying the orbiter manually.
-
Getting Hubble data through TDRSS, so will pass through that way, LOS in a few
-
Ku has been in radar mode for two hours now.
With switching to manual phase (last 100 feets) do we get some views from cameras?
-
10 second MC4 burn in 1:20

Both correct. A 2.2 fps burn requires 10 seconds to trim using RCS.
-
Ku has been in radar mode for two hours now.
With switching to manual phase (last 100 feets) do we get some views from cameras?
Yes, the crew will configure Ku for COMM at 100 ft. TV coverage depends on TDRSS.

Current position of STS-125 (and HST)
-
Thanks Davinator :)
Atlantis riding up the R-bar to Hubble.
-
Crew can command the telescope, just cannot see telemetry on orbit
-
within 400ft.
-
Sounds like they are little behind on the HST commanding, so they are going to drop the commanding to roll the telescope (42 degrees) and Scott Altman will change the orbiter yaw to account for that...the commanding would have required approx. 16 minutes...
STOCC waiting for TDRS link...
Crew just called 300 ft (range)
-
-
-
Crew stationkeeping where they are...range of 250 feet...STOCC now commanding HST through TDRSS...orbiter PI has lock...
Waiting to complete commanding sequences...
-
Stationkeeping @ 280 ft

The yellow are vernier thrusters, white are regular.
-
Stationkeeping @ 280 ft
Take the yellow range/rdot with a grain of salt. The onboard nav state is walking off from the radar. They're really about 250 ft right now. Crew is flying with raw radar and HHL.

Computer Geek Question: Is all this mission control software 100% custom, or are they using STK as a framework?

The former.

CAPT Altman must be having a ball doing all this manual flying of ATLANTIS!
-

Correction: the maneuver would have required 16 minutes (commanding probably not so long).
-
A trajectory mess:
The actual trajectory is probably fairly smooth, but the onboard state is diverging periodically (the crew is periodically fixing that by reinitializing the covariance matrix). Raw radar data looks a little noisy as well. HHL marks aren't downlisted so that's why MCC is asking for the crew to voice them marks every now and then.
-
CAPT Altman must be having a ball doing all this manual flying of ATLANTIS!
I was thinking the same thing. It appears to be a lot different than trips to the ISS.
-
Com through TDRSS! Lets see Hubble!
-
Hi guys, nice following this!! Just a quick question: Where can I find the Flight Data Files of STS-125? Searched on the usual NASA site but can only find the previous missions, not the 125...Anyone? Thanks!

"Geek mode off"? You are in the *wrong* forum for that. ;)

-
There she is!!!
-
She looks great!
-
Commanding from the STOCC should be almost complete now...Atlantis yaw maneuver should take about 3.5 minutes...
-
Looking good!
-
3 extra minutes for yaw maneuver
-
Can't wait see some high res photos from this.
Go for grapple!
-
Commanding complete, go for grapple. Range currently about 150 feet.
-
Seeing Hubble again is just beautiful!
-
Hubble is in amazing condition for being out there 7 years.
GO FOR GRAPPLE!!!!!!!!!

Saw this link earlier in a topic, but it says sts-119 instead of sts-125...I can find all the other sts mission data files except for this sts-125 hubble mission...Someone added a picture from the terminal phase/approach to hubble, where did you find it??
-
Go for grapple. 150 feet distance.

When is next 'scheduled' entrance in shadow?
Beautiful! :)

Try clearing your cache, as the files really are at that link...
-
will lose ku from telescope through TDRSS, will come from orbiter
-
ETA to grapple is now 15 minutes
-
will use ku from telescope through TDRSS, will come from orbiter
HST high gain antennas are retracted and the orbiter is probably going to block the low gain antenna link to TDRSS...
-
Crew now doing the orbiter yaw maneuver at range of approx. 130 feet. I believe PAO Kyle Herring said they are more or less holding at that range to do this maneuver.
-
-
Yaw maneuver complete...expect TDRS West in range for TV in less than five minutes...resuming approach from 137 feet.
-
Range now about 100 feet.
-
-
should get ku back soon
-
-
HST (the bottom of it) now in the RMS end effector view.
-
HST CAPTURE on 3-6 of the PDRS 125 checklist should be worked any moment (for those who like to follow along).
-
-
Grapple target coming into field of view
-
Never mind -- RMS in motion, so orbiter in free drift.
-
Lined up, moving in for grapple.
-
-
-
Over the pin, rigidizing, grapple confirmed by CDR.
-
And we have a grapple! Well done Megan!
-
Nicely done! :)
-
capture!
-
Ground verifying that HST is in drift mode, will call back shortly.
-
Wow...Megan made that look really easy! Well done!
-
Right on the Money!
-
Smooth!!!!!!!!!!
-
Amazing when you think about the thousands of miles an hour both the arm and telescope were moving (I know... relative motion)
-
HST TO DRIFT MODE being confirmed by MCC-H. (3-7 of the PDRS C/L).
I think the crew are unable to confirm this themselves due to problems earlier with the BSA.
-
Expected to see more space debris damage on Hubble but it doesn't seem apparent at first glance.
-
Crew asking to terminate rendezvous ops, ground says to hang on.
-
ITEM 7+ 91 requested by MCC. This is to again issue the HST DRIFT mode.
-
Ground asking to maneuver the arm to published position in HST BERTH 3-9. That should facilitate the STOCC getting lock on low gain antenna for commanding.
-
-
PAO says orbital sunrise in about 4.5 minutes.
-
After the arm reaches the published position, they're going to do an orbiter maneuver to different attitude. Thought I heard CapCom say it would be about a 30 minute maneuver.
Edit -- reading up the maneuver data to load, but are going to try one more thing to get lock first before executing.
-
I heard around a 30 minute manuver too. Presumably these DAPs provide very low rates to protect HST.
Manuver prelim:
R 175
P 090
Y 000
DAPs for manuver are: A15 and B12.

Edit -- reading up the maneuver data to load, but are going to try one more thing to get lock first before executing.
That thing was to try an antenna swap...trying now.

So when do we observer berthing in FSS? Im messed with all datas and changed hours.. Thanks for answer!

Have to verify the telescope is in the right mode before berthing, so have to establish comm with it. Working on that right now.

just caught up with the events today! Hubble looks beautiful... cant really see any MMOD hits.. so awsome to see this landmark of exploration agian.. go get um CREW... nicly done.. beautiful grapple..
anyone else follow Mike massamino on twitter????

The 1200k ones are stretched a bit, he is using the lower bandwidth ones that are not stretched
-
no television for 30 minutes due to ku dish blockage, so no live berthing on tv
-
brakes on arm, latches are going to be closed around telescope
-
HST will be berthed using the BAPS (Berthing and Positioning System) which is the active part of the FSS cradle.
-
Confirmation that HST is berthed. All three latches closed.
Confirmation of good link to the telescope through PI, ready for ungrapple.
-
Next up is the photo survey right? go for ungrapple
-
Hopefully the crew will be able to downlink some video of the grapple later?
-
Can't wait for the views from the payload bay cameras now that Hubble is berthed.

Question: Since Hubble is berthed on it's bottom, and the SCM will attach to the bottom, will they have to un-berth to do the attachment?
-
-
really wish they would switch to the end effector camera...

Complete with first 2 steps of survey.
Sounds like they are ready to download first images of survey to MCC-H

Question: Since Hubble is berthed on it's bottom, and the SCM will attach to the bottom, will they have to un-berth to do the attachment?
No, they only have to drive a single bolt during EVA 1 to secure it to Hubble's underside. It will be attached in the current berthing mechanism, IIRC. There's some info about it in the EVA preview conference http://www.space-multimedia.nl.eu.org/index.php?option=com_content&view=article&id=4893:sts-125-program-mission-and-spacewalk-briefing&catid=1 (http://www.space-multimedia.nl.eu.org/index.php?option=com_content&view=article&id=4893:sts-125-program-mission-and-spacewalk-briefing&catid=1) or in the Press Kit (page 40-41)
I know I always say this, but thanks a million to everyone that's keeping such a wonderful (and epic, I should add) coverage here. Much appreciated for those of us that can only get to a computer for a pair of hours at most during hectic May!
-
-
talking about downlinking images (hint for L2 contributors)
Just because they are downlinking the images doesn't mean they are guaranteed to show up on L2. I bet some will, others will be free, but it's not just L2 users that will get them.

Yep. It has been seen alot during this mission.

Goddard still doing commands with HST, but it sounds like crew is done with arm for today.
-
There was a remark made about one of the cameras used to affix HST to the FSS having been on STS-1, anyone remember what was said specifically?
Apparently it's the camera that was used in Columbia to see images from the payload bay towards the crew cabin during STS-1, and now it's being used as a centerline berthing camera (in fact, it's already been used) for the FSS.
-
There was a remark made about one of the cameras used to affix HST to the FSS having been on STS-1, anyone remember what was said specifically?
The camera under the FSS being used for B&W coverage was used for in-cabin color photos during STS-1.
Edit: eergo beat me to it. Thought they said this morning it was in-cabin, but he's probably right.

Tony looks happy
-
Successful day, HST grappled and berthed. Good teamwork some com hick ups, will finished up surveys, EVA 1 tool config done
-
very excited, want to thank SSP and everyone else, looking forward to EVA activities, wanted to note that when first saw Hubble there were gasps of elation, amazing sights of Hubble on the arm with the earth in the back ground. John called down that it was an amazing sight, still great looking after 19 years
-
Harwood: Go out early?
Plan hour and half after wakeup, but will try to get out early but not much earlier.
Q: Pictures of fine particulate?
A: contamination, dont know what it is, be aware that it is there but no big changes to eva
-
Mark C: surprised at condition?
A: Did not see anything, John says it looks in good shape
Q: Communications problem question, could command but not see response so had to relay to crew, how unweildly
A: Not simulated, but something similar. Crew and HST could command, but no feedback to crew, lost TDRSS but had plan switched to back antennae and pressed on.
-
If had to loose tasks, what would they be?
A: worked hard preflight to get high priority items done. First ones done first, only would have to move up battery swap.List of priorities gyros,batteries, science data unit, Whitefield 3
-
Reuters: Sense of relief, what did you feel like?

Bornstein: Asking about degradation:
A: Has been in the past, do not have that quantified, astronauts will have a good look tomorrow. Cannot quantify right now but expect some from previous experience.
Bornstein: Debris on cover, so should not affect instruments.
A: No idea what it is, worried that it could get on mirror, but contamination guys are ok with it.
Bornstein: Focused inspection?
A: No inspection on chine, enough data that no more was needed. Still have the rest of the vehicle, will yeah or nay at 5 pm est.

No action required, but they are tracking a conjunction ("yellow"). Closest approach currently estimated around beginning of crew sleep period.

ok, break is over, back to my real job :)
-
LeRoy saying how nominal and uneventful the grappling and berthing sequence was.
Some funnies: R5R thruster degraded chamber pressure. Keeping watch in it, although there are workarounds for stationkeeping if it should completely fail.
WLE impact in 11R panel (.47 Gs -corrected-) Probably real impact, also shown in adjacent panels. But not concerned about damage, certainly not critical. At most, coating damage.
-
WLE impact in 11R panel (4.7 Gs) Probably real impact, also shown in adjacent panels. But not concerned about damage, certainly not critical. At most, coating damage.
I believe that was 0.47 GRMS.
-
All TPS cleared for tiles and blankets (that leaves the RCC) No FI needed for TPS. RCC was more than 90% complete when MMT finished, so probably won't need any further inspection there either. Decision in 2 hours. Tomorrow, DAT will formally clear RCC in the MMT.
Vehicle very clean, pleased with performance.
-

-
Ascent performance really good. More info on that when the post-flight assessments are out.
Hubble team looking at the debris particles/contamination in the payload bay. They have plans to deal with those. Advising the crew to keep out of their way, and avoid them getting close to instruments. Just a slight nuisance.
-
The WLE IDS is 0.47, not 4.7.
They don't usually even look at anything less than 1.0 Grms, so surprising they would mention it. Over 10.0 Grms is where it becomes a worry, depending on mass, size, which panel etc.
-
Impact load to cause damage to RCC: function of panel, and location within the panel, as well as size, angle... many variables. But a handful of Gs, so nothing like the .5 Gs recorded (thanks for the correction Phillip... do they measure in grams or in Gs?)
Contamination, they think, is something getting from underneath the blankets. Definitely, absolutely, undeniably weren't there before launch.
-
A picture of the location.
-
Contaminants are aft of the airlock, on the first truss with Hubble hardware (on the SLIC, therefore - nice picture by Chris just above :) )
Impact on leading edge was detected within the last 24 hours. Not surprising.
-
Possible debris conjunction: yellow category. Probably nothing to worry about, but still tracking the item.
-
RCC assessment expected to be completed today (only 10% left) Tomorrow at MMT will be officially clear.
-
Chine damage: it went through normal assessment by DAT. Relatively small dings and scratches, superficial. Inner area of the tile is pretty thick, so no worries there. Not really even close to being critical.
Looked at how the increased heating in one would affect the increased heating in the one behind it, but fundamentally, it was relatively small damage, no action required.
-
Contamination looks like coarse-grain salt sprinkled over the handrail, without high density areas. On MLI, about a dozen particles, smaller than the tip of the small finger.
White in color. Will release the pictures. No particles on the thermal cover (on the airlock, right?) Just telling the crew to be careful with how they grab the handrail, because they can avoid it, as well as when opening the latches on the SLIC without disturbing the contaminated MLI.
-

The unit used is usually Grms - that is G root-mean-square (not grams).
-
Still no info on when the yellow-classed conjunction with the debris will take place.
Impacts of the pad debris/lightning strikes. 39B and Endeavour are ok, lightning didn't cause damage (as far as they have checked) 39A can be repaired within the last week or so.
-
The unit used is usually Grms - that is G root-mean-square (not grams).
Effective Gs, understood. Thanks!
For possible debris avoidance maneuver, nothing agressive like OMS assists can be done, less so when Hubble is docked. Only slight RCS corrections.
-
Still no info on when the yellow-classed conjunction with the debris will take place.
This was called up to the crew just before the briefing began, so Mr. Cain probably didn't get much info...CapCom said it was around the time of the beginning of crew sleep...

HA!!! When speaking of the rendezvous, CAPT Altman made the "I was inverted." hand gesture. Very appropriate since he flew that scene in Top Gun.

Depends on where the 16 tiles in question are. The RMS is on the port side so it's an easier reach.

The Orbit 2 PAO Pat Ryan said they are below the left-firing thrusters on the FRCS. Not sure if that's below the FRCS module itself, but that's the general area.
-
Apologies. Let me rephrase my question.
Is a visual-only inspection via the SRMS video camera likely to be considered sufficient for these 16 missed tiles, or do they need the LDRI to make this determination? Since the RPM is obviously considered useful, I'm guessing a visual-only inspection is sufficient unless damage is found, is that correct?
-

Right, the SRMS wrist camera can do the equivalent of an RPM visual-only inspection, then they can haul out the OBSS if needed. The camera is much lower resolution than the 400 and 800 mm lenses used for the RPM but it will also be much closer.

This is probably heading more to the Shuttle Q&A topic, but I thought the OBSS sent down one 3D image out of the 4 that it takes, which is why the camera flickers? Or am I completely messing that up?

Sorry to go back in time.... Does someone have a link to the detailed black and white mission summary timeline? Analogman posted a couple pages on page 1 of this topic this morning.

I don't see any on P1 - are you talking about the stuff from the execute package?

Oop. Page 1 is a variable. It was reply #20. I'd found this complete summary a mission or two ago from another source but can't track it down this time.

I know this is is a little ahead of the timeline, but since there's not much going on right now, I was reading the flight plan and noticed a ship-to-ship call from Atlantis to ISS on FD10. That started me thinking, can the ISS crew see the HST and/or Atlantis and vice versa? I know they are at different altitudes and orbit inclinations, but at some point the orbits cross each other. (See picture.) I did some reading about orbital mechanics but didn't really see this in there.

Just a general comment about the STS-400 "Emergency Shuttle". The news media sure has a short memory. The Emergency Shuttle was a Constraint for whatever mission was next. Ever since our third RTF; I refer to three since #2 involved MPS and did ground the entire Shuttle Fleet. I was Columbia's MPS Lead Engineer at the time so it was a short RTF situation in that regard but it was a "Shutdown" of all Missions as directed from NASA Level 1. OK so we have Return to Flights - 1st, Post Challenger 1986-1988, 2nd, MPS Hydrogen Leaks of Columbia, summer 1991, and 3rd, Columbia reentry disaster Feb 2003. Following the last Disaster and stoppage of all Flts, most of the attention was directed into how to inspect and fix the ET section that broke off during early Ascent impacting the left wing's RCC. Extremely high on the Orbiter's "Crit 1 list" was the impact detection system sensors on the inside of the RCC and the techniques, new glues/thermal materials and the Design and Implementation of the Extension and Inspection Laser Boom needed for on Orbit TPS location and possible repair. There was always the worst case scenario whereby a certain type of damage may not be repairable on Orbit. That meant going to ISS until a rescue shuttle or some "other system" could bring back the temporarily ISS stranded Shuttle crew. I seem to remember that NASA always had a "Rescue Shuttle" on "stand-by" ready to go (or very, very close) for every Post Columbia Mission, am I wrong? I know some of you all remember? I'm 95% sure, off the top of my lil head and without making a simple call to KSC, that we have always had a Shuttle on "Stand-by" called STS-400 or maybe an earlier term other than STS-400. Also let's remember, Hubble has been in its current "debris prone" orbit for all these years (since 1990) and has not sustained any hits worthy of mention and it has very little orbital transfer ability other than position/pointing. Hubble is the size of the Shuttle's Payload Bay and the Solar Panels are begging to be hit, they have not. Eventually, yes, but hopefully not till after Hubble's final Photon is captured!
-
The difference is that this is the only time the "emergency" shuttle was at the pad, so it gives the news media something they need -- a visual.
-
Thanks for that clarification.
Ever since post Columbia there was a new ground rule for a "Rescue Shuttle" or maybe they called it the "Backup Shuttle". It was "ready to go" within an allowable emergency "Time to Launch" window. That seems like what I remember. Your comment is so true about the Rescue Shuttle at the Pad! Such a big Press topic and photo Op overtaken only by the Swine Flu, CIA Memos or the New York City 747 Flyover! :)
Thanks
