LIVE: STS-120 Flight Day 11 - Preps for the epic EVA-4

[Chris Bergin]

Timeline for FD11 TBA as we await confidence of FD12 EVA-4 and the timeline that results from this decision.

Articles:
http://www.nasaspaceflight.com/content/?cid=5270 - When it happened.

http://www.nasaspaceflight.com/content/?cid=5271 - Exclusive on the plan as it emerged.

http://www.nasaspaceflight.com/content/?cid=5272 - Exclusive based on the plan as it came into place

http://www.nasaspaceflight.com/content/?cid=5273 - Exclusive on ground testing and timelines after repair.

L2: Super Hi Res Images of the plan being carried out on the ground. Numerous presentations on Robotics involved, OBSS, stage planning, etc.etc. and more.

We'll refine as we go, this is going to be something special...NASA and its contractors at work, solving a problem, via the mindset that got us all interested in the space program.

Why am I sayng this now and not at the start of EVA-4? Because it's all about planning and proceedure. I personally know a few guys working right now, working overtime, with mugs of coffee, running through every tiny eventuality, making sure Scott goes out there with several hundred people covering his back.

Just remember that the next time you read an article on some site, using words like "risky gamble, bad year for NASA" etc.

Good morning Discovery!

Wake-up song is "World" by Five for Fighting played for Doug Wheelock, who subsequently dedicated it to the ground support team.

mobile transporter will move from worksite 8 to worksite 3 to grapple to OBSS in a few moments

mobile transporter is arrived at the worksite

edit: mobile transporter is on its way to the worksite

edit:edit; PAO totally confuses me now, but she says the MT is still at worksite 8

I have confidence that these Astronauts can pull it off (the EVA I mean). We've seen things in the past where the somewhat impossible was possible. This one could be one of those moments to do that, yet again.

I too also like the title "Epic EVA-4."

And let's not forget that this is also a huge accomplishment for Mission Control and everybody that worked on the procedures to give ISS a fighting chance at fixing this array.

I'm curious - I read in one of the many posts... that the parts for the cufflinks were flown as contingency parts - sheet aluminum, 12 gage wire and connectors - does anyone know when they were brought up?  It would be really something if they were actually brought up on Node 2!

[haywoodfloyd]

So it looks to me like they will pre-position the OBSS attached to the SRMS with the SSRMS in close proximity so it can be grappled quickly to cut the margins on the OBSS time constraint.
If so, that is one smart move.

That also alleviates my concerns about translating the MT/SSRMS with a load!

[James Lowe1]

Chris is going to be very busy with L2 and articles today so if we can all help wity images etc, thanks.

[Chandonn]

I would like to interject one observation about ISS from this flight.  As some of you know, I'm one of those crazy people who updates his ISS model as the real ISS updates on orbit.

On this flight, when P6 moved, it became VERY apparent how much ISS now dwarfs the shuttle.  When Discovery undocks and does the fly-around, the shear size of ISS should be much more impressive than on previous flights.

[uko]

SSRMS has unberthed the OBSS and is moving it to handoff position

[ItsyAndy]

If I understand correctly later the SSRMS will move back to worksite 3; why if it will have to grapple the OBSS again tomorrow? Maybe I missed something.

It will hand the OBSS to the shuttle SRMS today (which will provide power for the OBSS and keep the sensors from freezing).  Tomorrow, the SRMS will hand the OBSS back to the SSRMS, which will be at the worksite ready to go!

Hope that helps!

That's clear. What I don't understand is why the SSRMS has to move back and forth again from different worksites and can't just stay in place for tomorrow.

Has to ride along the truss to reach the Shuttle, then go back to the array. Large distance. This has been explained on the previous flight day threads.

I guess the SMRS isn't capable of moving the OBSS to the handover position without running into ISS hardware. During TPS inspections, the SRMS can move the OBSS to nearly any position, but then you don't have to worry about ISS clearances ...

[Martin FL]

OBSS now with SRMS.

Thanks Andy, glad someone understands this is a live update thread

If anyone has questions, on the array, most which seem to be previously answered, post them here: http://forum.nasaspaceflight.com/forums/thread-view.asp?tid=10542&start=1 I've moved two recent posts there.

No.  The SSRMS will move back out to the array today.  It can reach the OBSS from there tomorrow now that the OBSS is unberthed from shuttle.

wrapping up cutters in air lock.

Cutters have a sheath (on station but not in photos)  Wondering about the sheath and taping.

Going to show MCC what they are talking about

MCC is going to talk about it and let them know!

I'm trying to get configured to take screen shots but I'm having a bit of a hard time

sounds like they are going to get ready to meet for the robo work conference.  Dan is giving kudos to the people that worked on the procedures

[Olaf]

I´m sorry, but I do not understand, why the SRMS need the help of the SSRMS and cannot direct put the OBSS.

[Andy_Small]

PAO  reports that robo work is behind on the MCC side

[Andy_Small]

shuttle arm is in Undock position till the work starts tomorrow

[Andy_Small]

Elbow pitch is about 2 degrees off of the norm on the shuttle arm.  Pam thinks it's fine but wanted to report it to MCC.  

They are go to push on but MCC is looking at the joint angle

I´m sorry, but I do not understand, why the SRMS need the help of the SSRMS and cannot direct put the OBSS.

The Orbiter arm (SRMS) is too short to reach the Solar Array with the OBSS.
It has to be handed off to the Station Arm (SSRMS).

@Olaf: I've written you a PM regarding this issue. Let's keep this live thread clean. I bet there is a Q&A thread dedicated to the P6 issue.

[Andy_Small]

Scott reporting that they can still use the sheath.  They just think they need to use more tape.  and it won't effect their operations tomorrow

MCC wants the sheath too just wants them to make sure they can get their gloved hands around the tool

I'm curious - I read in one of the many posts... that the parts for the cufflinks were flown as contingency parts - sheet aluminum, 12 gage wire and connectors - does anyone know when they were brought up?

According to the instructions uplinked to the crew on Thursday, the materials you mention came out of the ISS Pin Kit, Clamp and Bracket Kit and the Large Gauge Pin Kit. I'm not sure how often these are replenished (I'll ask after the briefings today), but a quick web search shows mention of at least the Clamp and Bracket Kit tracing all the way back to ISS Expedition 1 (which started its residency on the ISS seven years ago today, coincidentally).

You can read the seven-part instructions with illustrations that were sent to the crew here: How to build space station-saving cufflinks (link reposted on the advice of Chris).

All:  I can offer a final word on this.  SRMS uses the grapple fixture at the front of the payload bay only.  While undocked it can be reached but while docked the docking adapter and PMA2 are in the way so the SRMS can't pull the OBSS out of the bay.  That is the only reason why SSRMS is required whenever OBSS is needed and the shuttle is docked.

Location.  Currently in a LOS for a few more moments

[Joffan]

I know Dextre is on its way upstairs in early 2008 but the boom seems like a useful piece of kit to have around on the space station too. Does anyone know of a plan to leave one up there post-Shuttle? Preferably one adapted to be used by the SSRMS as it is by the SRMS?

[haywoodfloyd]

What would they have done if the rip had been on the far side of the panel?

[joncz]

Rotated it around the beta axis (as they did to take images) to put it on the near side.

[Andy_Small]

Anyways,  back to the live action

they are still in the air lock working.  MCC has tried to call them a few times.  

Finally got them.  Answering questions about the fish line.

[AntiKev]

haywoodfloyd - 2/11/2007  11:20 AM

What would they have done if the rip had been on the far side of the panel?

If you're thinking the further of the two arrays, they could probably use the BGA to rotate the plane of the arrays perpendicular to the truss and work on it that way.

[Andy_Small]

opps forgot the screenshot

bear with me.  I'm new to doing live updates

The current plan is to stow one on STS-123 on the S1 Truss.  Two support struts were installed on STS-118 on the S1 zenith trunion pins to hold it.  Their is a plan in work to provide power to it while it is stowed.  The sensors would still only be compatible with the SRMS and the SSRMS would still only grapple it from the middle.

Also getting ready to start EVA Conference

[wannamoonbase]

As a proud Canadian, living and working in the US and total space junky it is so cool seeing both Arms and the Mobile Transporter being used in such an huge improvised EVA.  The mission itself is impressive but the ability to improvise so much in such a short period of time is great engineering and problem solving.  

NASA, CSA and the contractors appear to be doing a great job on this.  Best wishes to complete success today and tomorrow guys.

[Andy_Small]

Orbit 2 has now taken over  per PAO

Conferences underway for robo,  then ROBO/EVA,  and finally a full crew EVA conference

[Andy_Small]

not much going on in the way of comm.  Crew must be doing that conference

Here's a shot of what I think is the SSRMS

[triddirt]

Just as an aside... I think I may have learned how to gauge KU availability (roughly)
It appears that when the white background bars are available on one of the TDRS bars along in the Detailed section of the timelines then KU is available...

I've been testing the theory against packages and events  (esp PAO events and the VIP event) yesterday plus live today... This is also being reinforced by comments in the plan itself.

If this is old news OR I'm off in left field let me know...

Thanks. That is now clear.

[Andy_Small]

Current Location

PAO just confirmed that conference is going on.

[Andy_Small]

MCC has told Dan that the mobile transporter is at site 8 and I would guess that means it's latched now.

[Bubbinski]

Yes, that is the SSRMS.  They just said the MT is now moved to Worksite 8 and they are ready to go.

Edit: This will be my only update as I have to go to work now.  Bummer.

Location update They flew near me and I forgot to go outside and wave  Darn!

[Andy_Small]

Go for exercise again.

Here's a awesome shot in the payload bay!

[rdale]

Don't think this has been mentioned -- a get-ahead task for EV2 will be the retrieval of an APFR which is suspect of having cut Wheels’ glove and past EVA gloves, for IV inspection.

[Andy_Small]

PAO reporting they are wrapping up the robo conference onboard.  Exercise is going on as well as transfer.  Robo/eva conference in about 30 mins.  All crew except Yuri will be doing a EVA conference after that.  Then Pre Sleep.  So that's the plan for the rest of the day

MSB at 1 pm CDT as planned.

No, after the EVA is complete they will return OBSS to the shuttle. If the sensors still work, which is expected, they will use it for the MMOD inspections.

[AntiKev]

Between the launches of the two parts of the Japanese lab (STS-123/124??)  Because there's no room in the payload bay for it with (I believe) DEXTRE and the one Japanese module.

Edit: Nevermind...misunderstood the context of the question.

[Andy_Small]

Getting ready for handoff to Orbit 3

[Andy_Small]

From Air Lock:  Robo conference is done.  Getting ready for EVA/Robo

Scott would like to talk to EVA people. They have about 6 questions for them

[Andy_Small]

Shuttle is going to be unmanned for the EVA conference.  But crew will be in the lab if needed.

From what I gathered the conference is on a privatized s2g  They are using netmeeting for video

[rdale]

MSB delayed to 230pm EDT

I know we're up to our ears in Apollo 13 references right now, though certainly the danger to the crews is nowhere near the same, but the Canadian arm folks remind me right now of the Grumman folks taking pride in the LM taking on a new role as a lifeboat.

No, this isn't what the boom was intended for, but it will still do the job..

Scott's in for one hell of a ride tomorrow.

[Andy_Small]

final set of EVA procedures onboard during lunch

[Chris Bergin]

Scott could put his hand on the array and wouldn't get a shock due to isolation.

[Andy_Small]

on a good array he could

but a damaged one it is possible.  but would have to touch metal on his suit

putting tape on tools and rings on suit

[Chris Bergin]

"We're treating the situation that there are hot wires on the panel" which is why they will conduct a full inspection prior to the repair itself.

[Andy_Small]

number of things have to happen before there is a shock hazard but still looking at it  Esp. due to damage

[Chris Bergin]

Dina Contella:

"The big picture really hasn't changed, it's now just the fine details."

"Boom tip will be on P1. Scott will take off his overgloves after installing foot restraint.

"Wheel's will be at the mast canister. He might work anywhere along the truss to help with the clearances."

[Andy_Small]

wheels will wear overgloves all eva

[Chris Bergin]

Scott will be a few feet away from the array. He'll lean in and out when near the array.

"We'll get up close and personal with the snag" before evaluating how to proceed.

Clufflink number 3 will be first. Installing into the center. Then clear the snagged wire.

[Andy_Small]

[Chris Bergin]

Scott will use the hockey stick to touch the array. This is an insulated tool.

[Chris Bergin]

One of the gripping tools is a Russian device (Dyno cutters). Used to grip the wire.

[Andy_Small]

don't expect alot of movement when the snag is cleared

[Chris Bergin]

Once the snag is cleared. Scott will trim the hinge. Then install the rest of the clufflinks (1,2,4,5)

If the snag does not clear. Cut the guidewire. Go to the base of the array. Tape over snagged area (to keep it all in one place). Clip the lower reel. Wheels will control the intake.

[Peter NASA]

Fun note for you all, but Startracker picked up an unidentified light source (no joke), so looks like this EVA has alien interest.

P6 is the priority that can be fixed now.  SARJ has too many variables to it

so that's why they are doing P6

[Andy_Small]

2-3 FEET of clearance

2 feet is the point at which they get concerned but worked with it before.  Lighting is more of an issue

[Andy_Small]

question of KU

WVS is going to be good.  Crew has flexabilty as to how to proceed.  Not flight rules on where to proceed.  If something is odd they might wait to get KU

[Andy_Small]

trying to get to a 30 min to air lock in case of emergency.  

takes 15 to get to truss

Scott has tested in the NBL and he can get there in about 8 mins she thought.  

30 min backup air supply plus remaining  in the main tanks

purge valve might need to be used untill you start moving alot.

still discussing about the 30 min

[Chris Bergin]

Derek describes Scott's experience as a safety blanket for this proceedure.

[Andy_Small]

Feels good about Scott's ability (duh)

okay pic of the hockey stick

[Andy_Small]

if not cutting and it's the leading theroy it will only take 30 mins

they think

[Andy_Small]

3 hours at the work site

got more from the robo work if they need video they think they can wait on it

REV L of TV schedule

again wake up call 12:38 am

5:30 am on the eva unless they are ready early

MSB over

Are they planning to keep Scott out on the boom until the array is fully extended in case more tears appear, or is he coming in and then they continue the deployment?

yes very slowly however.  and only if time allows in the EVA timeline

It was either one bay or one half bay at a time.

Probably.  These things are delicate so it's best to take it slow.  Easy-does-it does it best!!

You forgot to transcribe the response to that important question from Mark - one that all of us were wondering:

Ku video coverage isn't continuous from ISS to the ground.

Strange that he didn't know that... But now we all do :>

I just might stay up for a while to see this one!  I can sleep in tomorrow.  In terms of CDT, what time does the EVA begin?

[catdlr]

Thanks for the responses.  This has got to be one of the most exciting EVA for while and I can't wait to watch it tomorrow.  Hope everyone here gets some sleep, as this will be a long night (at least those on the Western Hemisphere).

Nathan - check the NASA TV schedule. And remember it'll be a long trip out there, so you don't need to watch most of the beginning and end.

Found it thanks.  Guess I can turn in and get up early, as the manuever to the worksite doesn't start until a little before 7 am CDT.  Good luck tomorrow Scott.

[Andy_Small]

EVA planned to start at 5:30

however could be earlier if crew gets ahead

...and that process takes up to an hour, so no need to tune in right away because that's a lot of boring motion to watch :>

Yup.  At a max speed of 5 ft per minute, it'll take the MT a little while.  Thanks for the heads-up.

[jeklund]

They have been geting out early on the other EVAs, and they'll be anxious to get out there.  I'll bet they are early.

That's CT - and that's just out the door time... P6 troubleshooting is planned for two hours later at 843am EDT (although of course could be earlier.)

A very good point. There's every chance this will happen earlier. Everything will be interesting, including the ride to P6. Anyone thinking just the repair will be interesting are on the wrong site!

I'm curious - I read in one of the many posts... that the parts for the cufflinks were flown as contingency parts - sheet aluminum, 12 gage wire and connectors - does anyone know when they were brought up?

According to the instructions uplinked to the crew on Thursday, the materials you mention came out of the ISS Pin Kit, Clamp and Bracket Kit and the Large Gauge Pin Kit. I'm not sure how often these are replenished (I'll ask after the briefings today), but a quick web search shows mention of at least the Clamp and Bracket Kit tracing all the way back to ISS Expedition 1 (which started its residency on the ISS seven years ago today, coincidentally).

You can read the seven-part instructions with illustrations that were sent to the crew here: How to build space station-saving cufflinks (link reposted on the advice of Chris).

Cool - thanx - just idle curiousity - I did check out the instructions you posted - definately calls back to Apollo 13!

[rdale]

These kits are up there specifically for the purpose of these types of unknown repairs - I'm not sure Apollo 13 carried spare items like this "just in case"

well yes they did: socks,  duct tape, plastic bags, a flight plan cover  :laugh:

[ApolloLee]

Thought this was interesting....... Bigelow's Genesis I is right now right on top of the shuttle:

Mind you, Genesis I is about 150 miles higher, but I half wonder if it may end up as another unidentified light source like Peter NASA mentioned earlier...

[Chris Bergin]

Could be a good call, though we don't have a time:

"-Y Star Tracker Unidentified Light Source" - now noted by MMT.

Not the repair, just the tools, like the CO2 scrubbing hook up on A13 or the flyswatters.

[Avron]

I note that this deploy will be one bay at a time... now there is caution.. learning?

[rdale]

Wouldn't it make sense to deploy it slow, knowing it's damaged? I'm not sure why you think they'd do it fast...

[JMS]

To be fair, we saw frayed guide wires and sticking grommets in the retraction of the P6 arrays, so we knew there was some damage before this weeks events. In light of that, I think Avron's comment is justified... there is some "learning" going on.
And in hind sight, if NASA could rewind the clock a few days, the initial deploy would most likely have shown the "one bay at a time" caution we'll see tomorrow... don't you think?

[JimO]

I'll be doing voiceover from home for MSNBC coverage throughout the EVA. Folks who can't get NASA TV, suggest they tune in there. And I'll be staying around these threads, in full compliance with Chris's media guidelines.

Epic EVA, tally ho!

[Bubbinski]

Orbit 3 team on console right now.  They just showed a neat tour of ISS on the Flight Day Highlights, and here's a live pic they just beamed from ISS:

saying EVA might be up to 45 mins early.  So at 4:45 CDT instead.  But will have to see how that goes

Let me second this ... that's a GREAT tour of the ISS interior, so go download the video from John44's site once he has it up.  It's right at the end of the video, starting at around the 25 minute point.  Paolo leads you around, from the Shuttle flight deck to the mid deck to the docking module through PMA2 into Destiny then Unity then Harmony then back through Unity and into the Russian segments.  The Russian part cut off before they were done, don't know if they lost Ku or what.  It's quite the labyrinth, and of course packed with Stuff.
