Title: Hail Damage at Pad A (STS-117) - ROLLBACK
Post by: voyager on 02/27/2007 10:45 am
Reports of hail damage to the ET tank from late yesterday.
Teams will inspect this morning. Potential rollback??
More to come.

More to come.
Hail damage is confirmed. Teams will be assessing whether the damage is severe enough to warrant a rollback to the VAB for reparis. All the damage is limited to the upper sections of the LOX tank.

Last time a stack was rolled back to the VAB for ET SOFI repairs due to hail was on STS-96. This only led to a 7 day delay of the launch. The launch was originally scheduled for May 20 1999, launch occured as planned on the new launch date of May 27 1999.

Just when everyone thinks NASA has the foam on the ET nearly fixed, this comes up. Will the woodpeckers return next.


But I agree one week is nothing. Lets play it safe.

Do we have any idea when a decision will be made?  A week-long delay won't kill the chances of launching next month.  It'll just be a little earlier in the morning for the U.S. guys to watch.  No big deal.

Worst damage observed (worse than previous rollback), 1000 areas of damage noted.

This isn't good guys :(

"At least" one IFR damaged.

Report on L2 also mentions about 1000 areas of damage, as opposed to the 700 areas on the STS-96 tank.  The report goes quite in depth and the images tell the tale.  Check it.  My money is on rollback.

This is getting really serious. Rollback pretty much a certainty (claims), but a new tank may even be requireed, depending on just how bad this is....and that really makes a mess of things, as per ET-120 situation.

Checking with LM/MAF.

Snippet of the e-mail/memo with TPS references:

"TPS inspections indicated that there were ~20+ hits on the left wing - severity of damage was not provided
Rollback is all but guaranteed - recovery time w/b based on severity of impacts"

Jim asks a question? :) My guess is leave it. They left P3/P4 in her PB when the STS-115 stack rolled off Pad B back in August. But then again the orbiter wouldn't have been taken off the stack.

Wouldn't it be smarter to remove the payload incase they have to demate, or can it still be kept in the Orbiter?  I am just wondering.

That's my thinking.  Handling/moving the orbiter around could be dangerous for S3/S4.  I change: Remove and hold in RSS PCR.

Here's the dates update:

Minor ET repairs in VAB - Possibly make the end of the March 25th window

Major ET repairs in VAB - Might be able to make the April 23rd - May 24th window

R&R ET with the 118 tank - STS-117 will launch in July and STS-118 will move to August 26th

Would probably have been cheaper to invest in hail-protection blankets for critical areas of the STS-stack on the launch pad...

Coincidentally I just got my viewing pass in the mail yesterday. I guess I won't be using it on March 15. I'm glad I did not make non refundable plane reservations!

This feels a little like 1995 again when I was going to see the launch of 70 when it was targeted for June and that didn't work out either.  :frown:

It's more likely that the hits on the TPS were flagged by sensors. That is all still being evalated anyway. The ET is leading the way on everything right now.

NASA Announces Feb. 27 Shuttle News Conference

NASA will host a news conference at no earlier than 4 p.m. EST, Tuesday, Feb. 27, to discuss the status of the space shuttle's upcoming mission, STS- 117. Topics will include the latest on possible impacts to the mission from a hail storm at Kennedy Space Center Monday.


The briefing will air live on NASA Television and the agency's Internet site from Kennedy. Questions will be taken from media at participating NASA locations. Media not at Kennedy are asked to call Public Affairs at their local field center to RSVP.


Senior spaceflight managers are at Kennedy for the Flight Readiness Review, a thorough assessment of preparations for an upcoming mission.

True. But I don't think they rollout if there's a chance of bad weather, so they have time to get RSS rolled into place.

I think that the damage to the wing is minor enough that they can do it while vertical.  I am hoping the ET will not need to be totally replaced.  That will be the worst case scenario.  They would have to demate and wait for STS-118's tank in April and not launch until June/July.  I am still wondering wether or not they will remove the payload.  I am sure many questions will be answered at the press breifing this afternoon.

FYI, this just hit the NASA Shuttle page:

Excerpt:
Quote
02.27.07 - 3:10 p.m. EST
NASA officials have confirmed that Space Shuttle Atlantis will roll back to the Vehicle Assembly Building for further assessment after yesterday's hail storm event. Additional details will be available at the press briefing being held today at 4 p.m. EST.

The weather pattern right now is very stormy, I live in Iowa and got nailed by the big one this past weekend, round 2 is due in Wed and will probaly last till Friday, figure when that one gets to the East Coast Florida will see more hail.  Large hail is not common in Florida simply becasue the air is usuually far to warm at the low levels to support the formation of the stones.  Large hailstones can make many trips up and down the storm before finally they are to heavy and fall to the ground.  Storms THIS time of air have plenty of cold air even in FL, so large hail can happen.  

I wonder why the RSS was not around the ship, it has the "garage door" protection for the back part of the wings.

Yup; the damage would very likely have been worse without it and the weather protection panels.

The storm you'll get has no bearing on Florida's weather, so odds are not very good at all for them to see hail again soon. The up-n-down hail theory seems to be falling by the wayside, thanks in part to 3D doppler views... Anyways I'll bring this in from L2 now:

Could have been worse - radar is indicating 2.5" hail as the cell passed south of the landing strip towards VAB! Here's a 3D view of the storm http://skywatch.org/kmlb-vol.png and output showing potential hail size (1.86" indicated in the diamond) http://skywatch.org/kmlb-mesh.png

That's actually a really interesting point.  But I don't think Endeavour will be ready to fly before the end of June.  But if Atlantis is in OPF-1 passed the planned time, I would guess calling up Endeavour would be a possibility.

In all seriousness though, Chris has done an outstanding job on this (as always).  Look forward to this briefing so that maybe I can get some images of the wing as well (no L2 for me right now)!

Appreciate it.

The way we run this media site is to have the open/free area better than anyone else, with L2 even better than that ;)

Here's two wing images (you have to blow them up and go searching). Not as bad as you would assume, but on visibility.
Title: RE: Hail Damage at Pad A (STS-117) - ROLLBACK
Post by: Almurray1958 on 02/27/2007 08:32 pm
Basically a chine is a change in angle between hull sections (boat building). In the case of the orbiter, a chine is the change of angle in the wing sections (steep to shallow).  Substrate is "the stuff beneath" the outer surface coating (coating is built-up over the substrate).  

So the translation would be : "The hail seems to have damaged the outer surface but not penetrated to the inner core material near the location where the angle of the wing changes."  

The results of the detailed inspection may render this discussion mute.

Hope this helps.

Lockheed didn't seem too hopeful, although right now that'd be the plan. Some of the things mentioned the presser were a bit off...such as the plan of five flights still being planned for 2007 - when the other week the fifth flight had already moved - documented - into Jan, as predicted a few months ago. Found that strange.

For everyone's sake, let's hope that they can repair in the VAB and not have to swap tanks.

Not really Lee as the hail was coming in at an angle.

So, it wasn't on and wouldn't have helped much if it were due to the hail being wind-blown.

I was just wondering.

I work in wind energy and we have test site with some pretty extreme winds.  Pebbles flying horizontally at 130mph are pretty damaging.  We had one guy get all four of his side windows blown out while he was driving to work and that's pretty good automotive safety glass.  The moral of the story is that I can imagine that even small wind-blown hail could be very damaging to something as soft as foam.

I would thing that they are worried about large chunks of now-perforated foam falling off during ascent and striking the orbiter, potentially causing Columbia-style damage.

The issues are mainly due to ice building up in the 'dents' and then coming off during launch.  Some weakening might also occur that would allow a chunk to break free and cause potential catastrophic damage

Slight imperfections will be ok, although you'd want to fill and sand down as much as possible. Indentations are dangerous because they could cryopump during the ascent and become debris hazards.

The 7000 number was acknowledged at the press conference, but they seemed to indicate that that wouldn't be the number of repairs they'd need to make.  According to them, the number is more "in the hundreds."  And that yes... some of these divots are a concern because of aerodynamics.

The RSS was covering the shuttle during the hailstorm but apparently they think the hail was bouncing around coming in every nook and cranny that was open, and the bouncing around is what struck the vehicle.

I believe they addressed this at the press conference, but I was somewhat confused by the answer.  I *think* they said that it's something they've discussed, but there was no real answer.  Another one of those "we'll see when we get into the VAB" type of thing.

As has been said, delays suck.  But at least they're going to do the right thing to ensure a safe flight.  No "go-fever" with these guys!

Interesting point there.

We all know NASA is continuing to be *safer*, and very open to any concerns raised from any area of the agency and contractors (you really see this with the "dissenting opinions" on PRCB presentations), but there was never a chance this would anything but rollback, to be honest.

Remember, they rolled back ET-100, with 700 areas of damage. ET-124 has 7000+ areas of damage.
Title: Re: Hail Damage at Pad A (STS-117) - ROLLBACK
Post by: jmjawors on 02/28/2007 12:47 am
Absolutely.  But I see a difference between this rollback and that one (besides the number of dings).  Remember that Mike Leinbach said that at one point they had tried to solve the hail damage at the pad back then.  This is a real demonstration of 'lessons-learned,' as that proved to not only be ineffective but dangerous.  

So recognition that this is a problem worthy of 100% scrutiny, and not just an inconvenience, is a positive thing.

Basically a chine is a change in angle between hull sections (boat building). In the case of the orbiter, a chine is the change of angle in the wing sections (steep to shallow).  Substrate is "the stuff beneath" the outer surface coating (coating is built-up over the substrate).  

So the translation would be : "The hail seems to have damaged the outer surface but not penetrated to the inner core material near the location where the angle of the wing changes."  

The results of the detailed inspection may render this discussion mute.

Hope this helps.<<<

Look at any pics of the Lockheed Blackbirds (SR-71, YF-12A); they have perfect examples of chines...

how come hail protection was never considered when building the service structure?

This size of hail is _VERY_ rare in Florida...

Absolutely. This was not expected.

This is the second time that a shuttle has been hail-damaged on the pad, as I understand it.  Shouldn't it be expected by now?  Will NASA learn a lesson from this that can be applied to Ares I ground processing?

What sort of lesson? Even under the cover of RSS, this was an extreme enough storm that the shuttle itself took some dings. So you'd have to seal it off basically to prevent any damage from a major storm, but by sealing it off you can't access it. Not sure there is a workaround...

Well, the first lesson might be that an RSS-type partial enclosure, combined with several weeks of pad exposure, isn't good enough.  Perhaps a complete enclosure is needed, at least for the upper stage and Orion spacecraft, in concert with a processing plan that keeps the vehicle off of the pad until just before launch to minimize its exposure to the elements.

Delays stink :(  

Have incidents like these delayed flights with other, more conventional rockets (e.g. Saturns, Deltas, Atlases)? Would we have to worry as much if this had been an Orion or Ares-V stack on the pad?

There would be some concern but ELV's don't care about ice falling or debris

The plan is to be on the pad less than a week.  The "other" plan is only the shuttle has to worry about this, not ELV's

If this or another problem pushes the launch schedule further back would the shuttle still retire in 2010 or could they go to 2011.

Or is there enough time for delays like this to finish the ISS in 2010.



Just found the answer on L2. Thanks.

No. Before STS-96 in May 1999, the tank got damaged by a hailstorm. Not quite as bad as this one though. They also rolled back to the VAB on STS-96 to fix the damage but the launch was only delayed a week because they didn't have other traffic at the ISS to work around. Also in summer 1995, Discovery's tank got damaged by woodpeckers, yes you read correctly, WOODPECKERS! They also rolled back to the VAB to fix that damage. Before the launch of STS-4, way back in 1982, they got hit by a hailstorm the day before launch and had to replace several tiles on the pad.

Hail damage is nothing new to ATALNTIS.  Back in 1990 the STS-38/ATLANTIS stack suffered minor hail damage. During rollback (for technical problems), the vehicle parked outside the VAB about a day while COLUMBIA/STS-35 stack was transferred to the pad for launch.

Hi,

I'm new to this site. My name is James. I work as a photographer, and was in Florida a few weeks ago for Atlantis' rollout. I noticed on a few of my photos what appears to be "dings" on the lower part of the ET. I have been wondering if Nasa was planning on repairing these spots at the pad, or were they going to fly with the ET in that condition. You can see what I'm talking about from the photos I shot on my site: http://www.freewebs.com/robmed/atlantisrollout1.htm ( You'll have to skip the ad when you get there, I've used a lot of bandwidth this month ). Is it common to launch with the ET in this condition? I wouldn't think so.

You mean Crawlers. The MLPs(Mobile Launcher Platforms) are just the mobile platforms on which the "stack" is mounted on.

The one that used to be waiting outside 39B to pick-up MLP-1 used for the STS-116/12A.1 launch has been relocated to outside 39A to pick-up MLP-2 with Atlantis.

I think you're referring to me.  The only dings I saw were on the back, so I thought that was what you were referring to.  Otherwise, I can only imagine that if Atlantis rolled out with the area in question that it must have been acceptable.  

I figured that was the answer regarding the bird, I asked only because I remembered the other photo so I thought it wouldn't hurt.  ;)

Welcome to the site James. Great pictures.

Currently, all further evaluation - and thus work to repair - will proceed once the stack is back in the VAB. The main areas of concern are the top of the LOX tank, Atlantis' left wing (nothing serious) and the top of the SRBs (as per NASA report today).

Today is about getting the payload out, then disconnects ahead of rollout will proceed.

The entire ET is covered with Spray On Foam Insulation(SOFI). The main basic SOFI is robotically applied to the ET while anything that has geometric shape is shaped by hand(PAL ramps, bipod ramps etc).

No steel in the ET. Would be too heavy. The SLWT is made of a Aluminium-Lithium alloy(Al-Li).

And yes, the damage is in the foam only.

They are first going to try and assess the tank and see if it can be salvaged.  The key, though, is that they need to get it inside so they have the proper access to inspect it.

Chris, can you confirm that they've decided to rollback with the hypergolic propellants still onboard, therefore rollback would begin around midnight Saturday?
Rollback is now Sunday or Monday as they have decided to offload the OMS/RCS propellants.

"Look at today's forecast for potential hazardous weather in Central Florida!!"

Best bet is north of KSC associated with a monster storm system moving through the east half of the country...

Good news on rollback delay - I'm on the "Up Close" tour Monday!

Where did you here that?  

Last I heard they were going to adjust the OMS quatity today because it was slightly over serviced during loading.  Rollout was still targeted for Saturday morning.

Thanks, as you can see I have pretty much tunned out the public information stuff because it is usually not timely.

I can see needing the extra time, but I am still not convinced this is a full off-load.  Like I said earlier I believe they are just adjusting the quantity - that is what I was briefed yesterday afternoon. I will check on this.

Jumping the gun a little but if we're talking late April/early May would this be a day or night launch ?

Yeah does any one know

To answer my own question, I have found an article from last year which suggested that if they wanted a daylight launch, then they would have to wait until the April 20 window.

For an April 22 launch, I think it will be around 1905 GMT (1505 EDT) or so....

I've understood all along here that they decided to fully-load the propellants and then that would be one less thing to do once they get back on the pad...

These events can not be postponed, therefore it means that STS-117 launch is possible from the beginning of May only...

It looks like I was late to the party on this one!

I had been briefed yesterdy afternoon about a potential need to adjust quantity of OMS do to slight over servicing. I was also under the impression that everyone had signed off on any potential need for the OPF with OMS/RCS as is.  Rollback was still set for Saturday at that time.

I was really amused/surprised that Dave S found out the correct info this morning from the Main NASA Shuttle News Page - that is the last place anyone would look for timely and acurate shuttle news.  

Even the coda-phone from PAO, which is supposed to be the latest and greatest info (which it never is) for the media, wasn't updated until later in the morning.

I share your frustration with their website as a source of "news," but this time they were right on top of it.

All the literature I've seen certainly has a launch tower on the MLP but I've seen nothing about a mobile or fixed service structure..... Will Ares just be open to the elements?

From what I have gathered in the past, Anik works in high places and knows his stuff.  His info is currently at odds with the newest NET date, but remember that an April launch is by no means guaranteed even from a processing and repair standpoint.

Post by: mkirk on 03/01/2007 11:16 pm
I know I helped confuse things this morning because I had old/different information so let me clarify a couple of things.

The hypergolic deservicing is NOT a complete off load of ALL of the hypergolic propellant.  They are just taking off a significant portion of the OMS propellant (i.e. OMS Quantity Adjustment). This is a lot more propellant than I thought at first and it is due to a Safety Requirement for the OPF and not because of the slight overload that occurred on the OMS fuel earlier this week as I indicated earlier in the thread.

The RCS will not be deserviced.  A couple of news organizations have said the APUs will be deserviced before rollback to the VAB – that should go pretty quickly since they were never loaded this week in the first place. ;)

Payload removal is tomorrow morning and Rollback is early Sunday.

Initial processing plans are targeting Rollout to the Pad on March 31 with launch on April 23.  Obviously April 23 is written in sand and may change after further assessment of the hail damage or negotiations with the International Partners.

That is the situation as I know it, if someone has more accurate info feel free to correct me.

There is no plan for the OPF at this point, this is just a precaution in case the OPF comes into play after further assessments.

No. Most tornadoes are 50-100 feet wide. Florida rarely gets tornadoes. Put those two things together, and odds of a tornado hitting a pad with a shuttle on it are not computable...

Not "dumb luck", but just the rarity of that type of thunderstorm at the Cape (also note that in the past almost-50 years there hasn't been that type of "violent, quick-storm" that has resulted in major damages to either NASA or Pentagon LVs, or the support/fueling structures around them.)

Even if an SRB were to hypothetically be somehow ignited from a severe thunderstorm, it would not "explode" at all.
Worst case would be that some of the propellent would start to burn, and there are more than a couple of contigency operations in that case, both for Shuttle and other LVs that use solid boosters.

The SRB casings are pretty darn tough -- the chance of one (or both) of them exploding would be extremely remote.

LO2 and LH2 in the ET is a different story -- much riskier.  But then tanking begins hours before launch and there are, of course, stringent weather guidelines concerning this.

The MSS only covered the Apollo spacecraft.  It the Saturn V had foam like the ET, it would have still been damaged while in the MSS.  But it might not have mattered, only the shuttle worries about ice and not ELV's.

Ares will be out in the open.  Short time at pad (less than a week) is its protections

Welcome to the site Simon.  Probably better for the Shuttle Q&A section in the general discussion forum. ;) But SRBs have self-destruct charges that can be detonated by the RSO (Range Safety Officer).  The only time that has happened was STS-51L (Challenger Accident).  The boosters were destroyed about 37 seconds after the disintegration of Challenger and the ET.

EDIT: Yes, the vehicle would be destroyed completely.  I'm not sure of the consequences for the FSS/RSS but they wouldn't be good.  The other concern for any SRB ignition is whether or not the hold down bolts will let go or not.  There's a big discussion on that as well.  Very interesting stuff!

Welcome to the site :)

Undesired SRB ingition is bad, period. That has LOV (Loss of Vehicle) written all over it.

The worst situation is at launch, if only one lights. Hugely unlikely, but (and a good place to check) on Shuttle Q and A this is discussed.

Single SRB ignition scenario is HIGHLY unlikely with all the redundancy available (NSI's, cabling, capacitor banks, etc...).  BUT - IF it were to occur - yes a definate LOV and LOP (loss of Pad).

There is always an RSO sitting with his finger on the switch? I think if an SRB was ignited outside of a normal countdown (thunder boomer moves through and strikes the booster instead of the lightening supression system) there would be no one to throw the switch. I sure one of NASA's biggest fears is a SRB lighting inside the VAB.  It would be a curtain call for the Shuttle,Ares I, and Ares V. One only has to look at what happened on the pad in brazil a few years back to get an idea of how bad it would be.

I was actually thinking about accidental ignition during the countdown.  As for any other time, I have no idea :) Just pray it goes up and away into the Atlantic.  Yeah, ignition in the VAB mean NASA is done with any launch operations for several years.

Not to change the subject of SRB's but ran across some historical images of the last rollback of STS-96.
This will give you an idea as to how intensive the repairs can be and why these repairs are not performed at the pad.

I am even more certain that such an event is WAY WAY WAY, WAY down on the NASA Fear List...

I imagine there are good safety inhibits in place to prevent any accidental ignition by lightning or whatever--much like what youd see on an aircraft carrier or an air base with the ordnance--bombs, missiles, etc-as well as ejection seats in jets-those safety pins with the red tags-REMOVE BEFORE FLIGHT.

I read that Brevard County is under a Tornado Watch.

Not "dumb luck", but just the rarity of that type of thunderstorm at the Cape (also note that in the past almost-50 years there hasn't been that type of "violent, quick-storm" that has resulted in major damages to either NASA or Pentagon LVs, or the support/fueling structures around them.)


Also, many Florida tornadoes are little more than Waterspouts/Landspouts, though an occasional larger vortex like what struck Florida recently can occur as well.

The current system moving through may produce more hail. This was the system that destroyed the High School in Enterprise, Alabama...my home state:

I've seen what a tornado can do to a large school, having assisted with the survey of the Oak Grove tornado from 1998...so luck can have something to do with high value 'targets.'

 I seem to remember a waterspout photographed behind a shuttle stack from a couple of years ago IIRC.

Not to change the subject of SRB's but ran across some historical images of the last rollback of STS-96.
This will give you an idea as to how intensive the repairs can be and why these repairs are not performed at the pad.

Wonderful images.

Reminds me of the image of platform access used to changeout the LOX vent and relief valve on ET-119.

Those images and more can be found on the KSC Media Gallery website by searching for STS-96:

I've attached a medium res picture of the top of that tank from a perspective that should look familiar; this link references that particular image:

According to current plan, there will be Soyuz TMA-10 relocation from Zvezda module to Zarya module on April 27 and possible ISS orbit's raisings by Zvezda's engines for preparation to STS-117 and Progress M-60...

These events can not be postponed, therefore it means that STS-117 launch is possible from the beginning of May only...
 

On NASA.gov today:

Quote
A planned altitude reboost for the space station on Friday was cancelled and rescheduled for later this month. With the launch of the STS-117 shuttle mission delayed until no earlier than late April, Russian flight controllers now plan on two separate reboosts for the station.

The first reboost, now planned for around March 16, will position the station for the launch of the Expedition 15 crew and U.S. businessman Charles Simonyi on the Soyuz TMA-10 craft from the Baikonur Cosmodrome on April 7.

A second reboost on March 28 improves rendezvous opportunities for Atlantis’ flight and brings the station into the correct trajectory for the returning Soyuz craft to land in Kazakhstan on April 19 with Expedition 14 Commander Mike Lopez-Alegria, Flight Engineer Mikhail Tyurin and Simonyi.

Two issues here, the reboost and the relocation.  But so far NASA does not seem to be addressing the "Soyuz relocation" aspect of all this.  At least not on the website.

They probably have nothing new to report at this time on this. They're probably still talking about it. I don't see any reason why it couldn't be postponed.

I think that the Russians have gotten a little bit too comfortable with slack in the ISS schedule during the downtime between STS-107/STS-114 and STS-114/STS-121.

Now the shuttle is back and it's time to get used to the fact that assembly has restarted and there's no more slack in the schedule.

I notice that the NASA TV schedule does not list the rollback. Does anyone know if it will be shown? I would like to see at least part of it...

Probably not.  We usually stick to screen caps from the NASA webcams on here to give coverage.  It's not a heck of an event to keep up with on here but at least we can track it.  The most exciting rollout/rollback event we've seen was the STS-115 rollback reversal back in August.  Big excitement there but we know that isn't going to happen this time around.  We can expect at least 26 days in the VAB.

I will answer to the first sentence only and ignore other two...

There will be two spacecrafts on ISS after Soyuz TMA-9 landing: Progress M-59 - on Pirs module and Soyuz TMA-10 - on Zvezda module... Progress M-59 is unprofitable for performing maneuvers of changing ISS orbit... The using of Soyuz TMA-10 engines for such purposes is dangerously...

"If" Space Shuttle will enter very low orbit then, according to agreement between Russian and U.S. specialists, ISS must lower orbit by approximately 100 kilometres... In this situation we can perform such maneuver with using Zvezda's engines only... Therefore Soyuz TMA-10 must be relocated from Zvezda module to Zarya module prior to STS-117 launch...

I am not a specialist, but this information was gotten from my sources... If it is not true, then I am sorry...

Bravo.  Anik, I'm not sure if you can answer this one, but you seem to know more about Russian operations than most others on the site.  The situation concerning the STS-118 delay and Suni Williams' return seems very open-ended at this point.  It seems her stay will be extended indefinitely, as she cannot return on the upcoming Soyuz flight.  STS-117 is delayed to April for sure, and it doesn't seem feasible to place Clayton Anderson on that crew and swap Williams out at that point (I could be wrong).  With no flights between STS-117 and STS-118, it seems she must stay an extra two months.  Are there any other return options available for her at this point?
