Title: SCRUB: STS-134 - LAUNCH DAY UPDATES - April 29, 2011
Post by: Chris Bergin on 04/29/2011 07:35 AM
LIVE interactive coverage for Endeavour's STS-134 countdown.

This is interactive, but will remain focused on updates. Use the other threads.

List: http://forum.nasaspaceflight.com/index.php?board=4.0 - for items such as viewing the launch, weather and cheerleading posts.

The site will get very busy as we get closer to launch, so please appreciate the thread needs to run on updates, not random posts, and non compliant posts will be deleted by moderators without notice.

We broke the record during STS-133, and for a period it was absolutely crazy visitation numbers (500+ page impressions a second). Our servers - thanks to L2 members - are excellent, but we will protect the site in the event of overloading. In such a scenario, logged in members will be priority access, not guests.
http://forum.nasaspaceflight.com/index.php?topic=24313.0

Be very careful with posting non-official Twitter updates in here as it's now NASA and USA policy that those involved are not to use Twitter during events, so exposing such people will risk them getting into trouble and I don't want this site to ever be responsible for that, even indirectly.

Coverage will be centralized on this site, via these live threads and news articles, but  I will ''tweet" important updates via http://twitter.com/NASASpaceflight

Should a scrub be called , this thread will continue until the attempt 2 thread goes live ahead of the next tanking opportunity.

Should Endeavour launch, this thread will continue as Flight Day 1 updates, with new threads for each of the upcoming Flight Days.

Godspeed Princess Endeavour!

Per L2's coverage, there's a problem with the pressure in the Right OMS fuel tank.

LCC violation. Waiting for more.

Also, they will be monitoring performance during and after Fuel Cell start due to an IPR. Constraint resume count at T-9, but the report reads like they will clear it unless something striking is seen.

Took them something like 30 minutes to acknowledge the GUCP leak last time.

Has to be pretty serious for them to mention it, and then it won't be immediate on their side. Just the nature of how PAO works. Kinda understandable. Half the reason they say they are not working any issues that "would prevent us from launching".

That "smoke" is cold oxygen vapor from the LOX dump pond.

From L2: LCC violation with a pressure problem in the Right OMS fuel tank now classed as IPR-53 (correction, from previous 54). May send engineers to pad.

Can see GOX venting out from the MPS.  HD feed went down, so no screen shots right now..

Also, having to run out for a few hours -- not a whole lot going on besides tanking.  Should be back for coverage around 10am or earlier.  Will delete this note later today.

Would this be classed as a 'serious' issue or more of something that they would just like to have fixed by T-9 minutes?

Orbiter

LCC violation mean if it isn't fixed, we don't launch.  You can't launch out side of the Launch Commit Criteria.  They're still tanking, so it isn't a show stopper quite yet.  I'm sure they'll look into it. 

From the LCC rule set on L2, this is a constraint to coming out of the T-9 hour hold.

Yeah, we can throw things on really fast, and we have excellent sources. However, if Allard wanted to, he could open his mic and put it on the LD desk, and they'd then beat us....but that's a fast way for him to lose his job ;)

Plus, people watching NTV mainly includes "What's the T-minus time, when do the astros walk out" audience.

Here it's a "I want to see pictures of regulators, and I want to see them yesterday" ;D

Waiting on if the Crossfeed solved IPR-53. IPR-55 (later edit: renamed IPR-54 after initial 54 - venting observed, was cleared) now up, relating to an APU Heater trending low.

Requires some switches flicking on the flight deck to see what's going on with that (switching power feeds).

If anyone (like me) is wondering why their NASA TV public channel Windows stream doesn't work, it's because NASA have changed their Windows stream address.

This new address streams at nearly 700kbps. The 150kbps and 300kbps Yahoo streams (which is all my connection can handle) will no longer work.

The address of the new 700kbps public channel Windows stream is here: http://www.nasa.gov/55644main_NASATV_Windows.asx

Thank you NASA for fixing something that wasn't broke - now I can't watch the launch. >:(

Hmmm

:-[ Are you able to play the flash stream? > http://www.nasa.gov/multimedia/nasatv/public_flash.html

Nope - the bitrate is too high (I have a really slow connection).

I can just about manage to stream 300kbps, but during peak times (like today - bank holiday in UK) I can only manage 150kbps.

Even the Media Channel streams at 350kbps. Now there are no NASA TV streams with a bitrate of 300kpbs or lower - so effectively I can no longer watch NASA TV.

Lt. Col. Barratt in the firing room now.

Had a front that passed through this morning.  That caused all the RED conditions this morning.  That collected with seabreeze.  Seabreeze pushed it in here, along with the cooler weather, and that's what caused what happened last night.

Around 7:30, 8:00am, the front was a little active here.  Actually did pass through here at that time.  We were expecting to see things develop.  Most of the bigger storms passed to the south, fortunately.  Still have a little remnants passing overhead now, the clouds, expecting to clear between 12-1pm.

Looking at scattered clouds about 4,000 feet.  Winds were expecting to come out of NE at 12-18kt.  That's probably our biggest concern to RTLS.  Expecting favorable conditions for launch.

Concerns for low level clouds if this front slows down a little bit, and the winds.  Pad winds are expected to be in bounds.

NTD Jeff Spaulding is polling the team for any LCC violations before the crew does ingress.  Range weather is NO-GO due to low clouds, but do expect that to improve on the afternoon.

The rest of the team are saying GO, except for the one issue with the APU heaters.  Not a show stopper as of right now, but does hold some potential.

Per NASASpaceFlight twitter, scrub is coming due to the APU issue.  No official scrub as of right now, though.

Trying to figure out if the thermostats have anything to do with the heaters failing, and what can be done to troubleshoot.

(Note from Chris - thought I had posted, because I post here before twitter, but I messed up my browser windows, so posted again, but not before this post. This is IPR 54 failing to resolve with techs in the flight deck, see page 4 for first mention).

The 48-hour scrub turnaround at this point is really more for initial steps/work to back out of the launch attempt.  We'll get updated target dates / times as they understand the problem better.

Clearly found something bad with the APU, as we had "APU 1 Fuel Test Line Temp V46T0183A1 is 44 deg f s/b 45 deg F or above" 2.5 hours ago on L2 (the heater issue), but it was simply a case of sending a couple of guys to push some buttons on the flight deck.

Crew ingress time is usually a quiet time, so popped out, come back, scrubbing notices flying all over the place on e-mail and L2, posted it on here and twitter thinking "was that my fault for stepping out" ;)

3-5 days is what we're hearing. Min 72 hours. Will collate the L2 info and round up in the article.

Mike Leinbach in a huddle with Mike Moses, Jeff Spaulding, and Rita Wilcox.  Trying to assess what is going to be required and how much time they'll need.

Spaceflight is a tough business.  Better to take the time to fix the issue than fly soon, though.


Currently sitting on a 48 hour turnaround, but "increasingly likely" that will be longer.  Don't currently know how much longer.

Crew ingress time is usually a quiet time, so popped out, come back, scrubbing notices flying all over the place on e-mail and L2, posted it on here and twitter thinking "was that my fault for stepping out" ;)

Little do you know it probably was your fault. The LD probably was trying to message you about the issue and when you didn't respond he probably thought something must be wrong so he called the scrub  ;)

Mike Leinbach now on console.

APU number 1, provides hydraulic power to the Shuttle.  Thermostat on the APU is the issue.  Need to keep the lines warm on orbit to keep the fuel from freezing.  The thermostat had a hard failure, and we couldn't get it to fire back up.  Tried letting the line cool to let it kick itself on, didn't work.  Tried to turn it on from the cockpit, didn't work.

Another thermostat up the hill from this one is experiencing issues too.  Looks like we have a LCA (Load Control Assembly) short.  Didn't want to risk the mission with one APU failed, we'd lose some hydraulic power on re-entry, and that's something we do NOT want to do.

Draining the ET right now, about an hour to go in that.  Will set up to gain entry into the aft tonight, and will get into the aft tomorrow afternoon.  We'll have to set up our platforms to get in, and that's quite a ways in.

We'll test the LCA and the thermostats.

Minimum of 72 hour turnaround.  Going to have a meeting at 2:30pm EDT and see if we need to extend the turnaround.  Sorry to the *Endeavour* crew and Mark Kelly and his guys.

No less than 72 hours for sure.  Can't tell if we need to have more time until we get into the aft.

Doesn't sound like it, sounds like a problem with an electronics box that's also in the aft compartment.

Replacing an APU has been done at the pad (the aforementioned STS-31 issue being at least one case where that was done); however, it would be a longer delay and would require a lot more retesting (including a hot fire).

That's the truth!

Such a shame on reflection as they did so well to resolve the OMS pressure situation, and this APU heater problem certainly sounded like it'd be resolved or cleared as-is once the techs flicked some switches.

Post by: FinalFrontier on 04/29/2011 05:30 PM
not surprised at the scrub given the reason why. Too bad for all those onlookers though.

Guessing this is moderate failure and there is a good chance apu 1 will have to come out. Depends on where the short is and if flight confidence can be developed for the entire heater system after a repair is made or if they feel damage may have occurred as a result of the short (would entail full removal.).

I am not sure they would want to do APU removal at the pad.

Is the heater a separate unit from the APU or does the whole APU need to be  removed if that ends up being the solution? IMO I hope is an easy fix so Endeavour can fly.

I really don't think they would be removing the entire APU. Still need to see a full plan, which will be aided when they gain access, but I don't think we'd be talking about such a dramatic fix at this time.

The two running M/CH-53s in the photo are interesting.  The President will fly on the "photogenic" Marine 1 most of the time but the -53s are there as a backup in case anything unusual happens because of their better defensive capabilities...

While stationed in England, our MH-53M Pave Lows provided similar support when the President visited the UK.

Unusual for it to be as quiet as this about the start time, but given the President is there that would make sense.  We weren't hearing anything here either until a few minutes ago.

FWIW, the rumor here was maybe 4:45 pm Eastern, but maybe later.  Doesn't look like 4:30 pm happened, either.

It was a 757-equivalent, and any airplane with the President on it becomes Air Force-1.  The helicopter is Marine-1.

I believe they also take the 2nd 747 with them wherever the president goes in case there's a problem with the first one. They also fly a number of helicopters in formation whenever the POTUS is onboard.

I guess the extra 757 isn't that expensive if you compare it to the total cost of a normal trip.

Mike Moses praises the teams on coping with the late RSS due to the weather.

Five hours late on RSS retract, on time tanking.

Had a few things to deal with, notes the OMS pressure. Then had the APU problem. Had a problem with a hydrazine fuel line heater (leaky hydrazine is bad, fire hazard).

Two heaters. Need both to be working. Not a mission ending issue on orbit, just lose one APU and burn off the hydrazine.

Good call to scrub. Into a recovery plan. Wednesday 4th is the last attempt in this window. 8-9th on the other side, due to an Atlas owning the range inbetween.....but the 9th or 10th on the other side of Atlas is better because of Russian vehicles on Station.
Title: Re: SCRUB: STS-134 - LAUNCH DAY UPDATES - April 29, 2011
Post by: Chris Bergin on 04/29/2011 09:18 PM
Mike L - slower :)

Tanking was nominal, but the themo didn't come on as the stack got colder via tanking. Wasn't much to do during ET load, needed to go into the crew module and command from there. That didn't work.

Knew we had a problem. Did some talking and frankly this was a pretty straight forward scrub as it's a critical system.

Tank is drained. 24 hours to get to inert.

Sat afternoon will go into the aft of the orbiter. Have to get our hands on. Then troubleshooting, which will be spraying a can of mist to force the heater on, showing it would only be the thermo.

If it's more than that it could be the LCA, if there's something in that box it's a much more extensive job.

Right now the easy path will lead to a Monday morning launch. LCA issue, longer scrub.
 
Was kinda funny to hold the crew half way to the pad.

We will not fly this machine until ready.

Questions...on longer scrub (LCA):

Mike L - set up to try for Monday, able to go to Wednesday before standdown. Haven't given up on launching before Atlas. Changeout the box is a signifcant deal and a two day retest, that would probably drive us past this window (before Atlas).

How soon did you know it was a scrub situation?

Mike L - Within the first hour, 90 minutes, (two hours or so). We know these orbiters really well.

Mike M - saw it was the entire string of heaters.

Randy Segal (we know him :)) on APUs.

Mike L - both the other APUs were fine.

And Mark Kirkman...on 135's schedule and heater strings.

Mike M - 135 not yet directly tied, can go to the other side of Atlas and another week or two. No final answer, but not imminent.

It was multiple heaters on String B which was gone. String A was fine. We switched alternate power feeds to see if it was the ground power problem side on String B, wasn't.

Mike M - probably a feed to the whole string that's a problem.

Todd H on LCA changeout and astrovan fun:

Mike L - I can talk to the astrovan at any time. Didn't want to let them into the BDA.

LCA - working a detailed plan. Difficult to changeout and the good 48 hour retest on that guy. Access is on the left side of the ship. One entry level platform.

File 9 checkout is the name for the Heater checks. Mainly checkout on orbit by switching the strings. Last performance on orbit was fine.

On cutoff to go for Monday...

RSS to park Sunday afternoon 3pm. So need to get into launch preps at that time. Noonish on Sunday is the cut off.

Bill Harwood on Obama's scrub conversation and Gabby (bet Bill would have asked engineering questions if he wasn't given one of the last questions).

Bob Cabana - He said he understands, didn't really talk to him too much.

Would wind of delayed launch anyway?

Mike M - Was within limits. TAL sites - ZAR was go, just. Salt in the wound.

No firm commitment on the President coming back for the launch.

Mike M says they may talk to Atlas, but might be better to let them go. Dynamic situation.

Bob C notes Obama's kids had great questions about Atlantis.

James Dean on knowing there was a scrub coming.

Mike L - (proud) Well I know the ship very well :) Was a coincidence with the timing of the crew walkout.

Bob C - President had a physical and cleared to meet the crew per quarentine rules (interesting).

On how many heaters. Mike M gets excited and starts counting from a schematic :D

Each heater is a wrap around the line.

That's pretty much it.

Bob Cabana

Would have loved to see endeavour lift off this afternoon would rather be on the ground wishing I was flying than in the air wishing I was on the ground

Even though we scrubbed the president decided to continue with the visit and he and his family enjoyed it

Saw Atlantis in OPF. Came to LCC met with crew, (in good spirits). Met with crew families.

He understands its hard for folks losing jobs it will be focusing on doing bigger and better things.

Will have a good future with commercial space and a large vehicle to go beyond earth due to the tremendous work force at NASA

Hope to have him back for another launch

Crew staying in quarantine with families


Mike Moses

Team did an amazing job to get to tanking, weather front last night hit later than expected threw them into a loop for RSS retract,  and was 5 hours late but an on time tanking

Weather briefing showed good day to tank, leaky hydrogen fill line, hooked it up to different tank to bleed down pressure

APU Ė system used to generate hydraulic power,

Had a problem in one of heathers in fuel line. In orbit if you cant keep heater on line freezes up and when it thaws it make rupture the line. Leaking hydrazine causes a fire on re entry

2 heaters on APU 1 both required for operations. If you lost last heater on orbit you may not have time to react. If this occurred on orbit they would have evualted it and may have been able to periodically use to keep it warm. Would have burned it to depletion  would not have to worry about it. Wouldnít have had to terminate mission if one APU fails in orbit.

Team made a good call on scrub talked about it to make sure they understood it correctly. The hydrogen oxygen cooling the line provided a free orbit check out.

Atlas launch on 6th last possible attempt on Wed

Potential issues after that with Soyuz undocking, could undock with shuttle present but not dock shuttle at same time. Will need to talk to Russians


Mike Leinbach

Tanking went perfectly when fuel line chilled down the thermostat didnít come on. Had to get into crew module to command the heater on, needed to wait till ET load was done to do this.

Didnít work commanding it on from crew module.

Talked for a few hours about launching like this, was straight forward scrub. No redundancy on a critical component

ET empty now. 24 hours to fully drain little bit left to boil off, and then need to inert with helium

Tomorrow afternoon going into aft of orbiter and get hands on the fuel line, thermostat and heater.

First step will be to spray mist on the thermostat to cool it down and try and turn it on. If this works it may be a broken thermostat that needs replacing

May be a problem in a box called LCA. Box of switches, if somethingís wrong in this itís a big job and will take some time to change out.

Troubleshooting currently supports Launch attempt Monday morning




Questions

Q: If it becomes more invasive will you be able to make next launch on other side of Atlas ?

A: Are set up to try for Monday can go till Wednesday.  LCA change out is big. Retest requires 2 days.


Q: Did you meet Giffords?

A: No


Q: How quickly did you know this would be a show stopper?

A: Within first hour and half. Initial signature looked like it was just 1 element on line that failed, but after a longer period it was clear it was the entire string of heaters


Q: Will assume the other APUís are fine and not work on them?

A: Yes


Q: Are you tied to Atlantis in terms of schedule?

A: Not 1 to 1 tie yet, can go to other side of Atlas and another week or two without problems


Q: If you had to R&R LCA how long will it take?

A: Working on a plan. Difficult to change out. Retest takes 48 hours as there are multiple systems that go through it. A few days for sure.


Q: Why did astro van go to LCC parking lot ?

A: Started going to pad as they were still talking. Knowing they were going to scrub they didnít want them to go into blast danger area.


Q: Going into the aft compartment is hazard to make sure you damage nothing how much access will you need and do you have spare parts needed?

A: Need to go in left door of aft. Have all the spares needed


Q: Has this issue happened in the past ?

A: Similar failure before (doesnít remember number). Looked at history to give them a starting point. Heater performance is in file 9 checkout. Need to shield each individual thermostat to check them out on ground. This is time consuming so they check them out on orbit. If thereís no problems on orbit they consider them ready to go for next flight. Last issue like this was 2 years ago.


Q: Do signs point towards a thermostat failure?

A: It depends, a thermostat running a little low that doesnít function during checkout is a quick change out. All the heaters on front aft share a common ground so opening up causes it to pull down a switch in LCA box. So a single failure of a thermostat could still cause this failure.


Q:  Was the weather at the launch time go?

A: Winds at KSC were not a problem. TAL site (Zaragoza) was good.


Q: Will the congress woman stay for launch?

A: Donít know


Q: Any chance Atlas will move for shuttle?

A: Will talk to them


Q: How will the astronauts be spending the next couple of days ?

A: They will have time with families. Time at beach house. Going over procedures to make sure there ready and listening to how the teams are doing on troubleshooting. Mainly relaxing in crew quarters.


Q: Did the crew know before they even walked out a scrub was probable

A: They know the ship well so they probably understood it was a significant problem


Q: Does meeting with the president stretch the crew quarantine rules?

A: No president and first lady had a physical and were cleared.


Q: Do the two lines involved each have 4 heaters?

A: 12 heaters on line. Not all will cycle at pad temps. Only 4 will cycle at pad temps. 2 heaters per fluid line, 1 working, 1 was not.


Q: Does the switch box take so long due to testing or getting to it?

A: Have to get to the avionics bay and this is a lot of work. And retest is a lot of work.


Q: How does the weather look for Monday Ė Wednesday?

A: Donít know, doesnít matter much. KSC Looks like the same weather pattern as now. TAL weather should improve.

Q: Do signs point towards a thermostat failure?

A: It depends, a thermostat running a little low that doesnít function during checkout is a quick change out. All the heaters on front aft share a common ground so opening up causes it to pull down a switch in LCA box. So a single failure of a thermostat could still cause this failure.
This was a nice summary of what we'll be wondering about on the weekend.

Here in Orlando, our tour bus was just leaving KsC for the Causeway when they announced the launch scrub with Monday as a new launch possibility.

Considering the APU and heaters problem what are the chances thqt they would have Endeavour all back in 100 percent flying condition for Monday launch?

I will still be here on Monday qnd Tuesday but I won't be able to extend much longer after that.  I am asking one of you if they could give me a calendar of possible launch dates after Monday if they decide to postpone further.

Would pushing the launch date later not influence Altantis launch dats an if so how far in time can Atlantis launch be pushed without creating problems relating to budget/finacing that last launch/mission?

I really hope they have the shuttle fixed and ready for go on Monday still wanting to know what would hqppen fi they decide to postpone to a further date.

I would be terribly unhappy to have to return to Europe without seeing Endeavour off to the skies and up to Space.

Atlas launch on 6th last possible attempt on Wed

Potential issues after that with Soyuz undocking, could undock with shuttle present but not dock shuttle at same time. Will need to talk to Russians.

Now this is interesting - if the Soyuz TMA-20 undocking is permitted during the docked timeframe, then that means we could get a flyabout after all. :)

We simply won't know until they get into the aft tomorrow.  If the heater works, then it's a thermostat change.  If the heater doesn't, it's into the LCA and that could take a few days.  Please read what was transcribed above, it has all the answers you are looking for.

FWIW, from back when the scrub was first announced.  Not sure if either were what was being referenced:

For what it's worth...
STS 2 was delayed 8 days (for APU scrub)
STS 31 delayed 14 days.
Those were different situations, STS-31 turnaround was complicated by HST battery charging.

Take a look at this - from a NASA photo of the crew walking out from the O&C building to the astrovan - it seems they have already placed an STS-134 patch on the NASA logo above the O&C door (bottom right). I guess they really thought they were going!

Needless to say, only one patch remains to be added until that "patch wall" is forever complete. :(

Not official/definitive, but an indication of where this is heading......it's looking like the LCA is the root cause of Endeavour's APU heater issue, according to engineers in L2 (not single source - which is important).

Because they are still looking at foward paths for this, and the need for it to be official/definitive (still testing the system), don't go ruling out Monday as a launch date yet, but clearly the box being a problem is the one that needs more work, so it's not looking amazingly hopeful for Monday.

They'll probably decide and call it at the 10:30am presser. Anything official ahead of the presser, I'll post it.

Sry for the delay, just woke up, lol. When we scrub they automatically send tankers from the plant. Then we'll put them in the tank either after launch or when we have an extended scrub, so that we can preserve the option for as many attempts (usually 3) in a row as possible.

There are two factors involved in setting the date for the next launch attempt:

1. The time required to R&R and retest the LCA.
2. Does the Air Force Atlas 5 launch take place on May 6 as scheduled.  It takes more than 24 hours to reconfigure the range.

So don't make any plans yet.

If launch is on May 10th, undocking from the ISS will be on May 24th (assuming a 16 day mission) - the same day as the planned Soyuz TMA-20 undocking & landing.

So, launching on the 10th or later puts Endeavour at the ISS during the Soyuz TMA-20 undocking - which means there's a good chance of getting the Soyuz flyabout, providing DDO is approved (which is looking favourable per the post-scrub news conference on Friday).

If launch occurs on the 8th or 9th however, Endeavour will have departed the ISS before Soyuz TMA-20 undocks. For the sake of one or two days, I wonder whether NASA will deicide to move up the Soyuz undocking in order to get the flyabout done, since getting it done on this mission would seriously help out the STS-135 timeline?

No. It's either NET May 8 or May 10th. The teams are looking at the R&R and retest timelines now. That's why we're hearing either the 8th or the 10th.

They usually move the shuttle out to the pad a little over a month before launch. So if they get off the ground before on on the 10th there shouldn't be any delay for 135.

Hope you'll allow this question here?

How do they decide where the count will pick up from?

With recent scrubs they've continued from T-11 or T-6.  I'm assuming it depends on the tasks which have had to be backed out from? (i.e. tank drained so it has to be at least T-6)?

With the tasks undertaken this time (gained access to the aft of the orbiter) where might we pick up?

Its difficult to test the thermostats on the ground due to needing to isolate them and then cool them down.

So if theres no problems on orbit they assume there good to go for the next flight.

This is entirely speculation. There are absolutely no facts contained within these two responses for STS-135's launch date.

So, let's clear this up. The facts are as follows:

Atlantis is currently scheduled to rollout to Pad-A on May 18/19 or 19/20. It takes 11days to reconfigure Pad-A from Shuttle launch to Shuttle Rollout.

The STS-135 pad flow and Crew training timelines are EXTREMELY tight as is to make June 28.

Take from those facts what you will. But those are the facts, nothing else.

Title: Re: SCRUB: STS-134 - LAUNCH DAY UPDATES - April 29, 2011
Post by: Ford Mustang on 05/01/2011 06:07 PM
Mike Moses:

Teams been working really hard on the troubleshooting plan.  Been getting updates as they go.  Pretty good plan they had.  Leinbach will go into details.

Failure appears to be a power problem in the LCA.  Power isn't getting out to the heaters.

Teams had some options in case it was some ground issues (electrically ground).  Could have wired some stuff up, but this is an upstream problem.  Have to replace the LCA.

No current NET.  Lots of work to do, sorry to disappoint.  Looking at Atlas in between, and then after Atlas would be the Soyuz undocking while we are there.  Won't be any earlier than the 8th, but that DOES NOT mean we are launching on the 8th.  Still a lot of work.

We have a rough plan to pull the box out, put a new one in, retest, and launch, which is a lot of work to do before next week.  We're going to wait on the data before we make a lot of decisions.
Title: Re: SCRUB: STS-134 - LAUNCH DAY UPDATES - April 29, 2011
Post by: Chris Bergin on 05/01/2011 06:09 PM
Mike Moses -

 Notes it's not a ground problem, but upstream on the LCA, so no hotwiring solution would work, has to be a LCA R&R.

 MMT may meet tomorrow or Tuesday on the launch date, but the earliest we can launch is the 8th. That does not mean we'll launch on the 8th. Lots of deconflicting to be done with the range and ISS (Russian undocking).

 Very proud of the team.
Title: Re: SCRUB: STS-134 - LAUNCH DAY UPDATES - April 29, 2011
Post by: Ford Mustang on 05/01/2011 06:10 PM
Leinbach:

Lots of telecons over the last few days.  We are getting all our platforms set into the aft, not required for the LCA R&R, but are required for retest.

Disconnect ordinance, offload PRSD, then power Endeavour down tomorrow.  Takes us out of countdown status.  Need to take the old box out, put in the new box, and then retest.  Quite lengthy retest, did this once on STS-70 I believe.  Two full days of retest, 9 systems to test.

Will be a regular 3 day countdown when we get back into it, start from ground zero.  Reload PRSD two days before launch.

The team always likes a good challenge.  We'll be really glad when we get in orbit, but the team is ready to go for this.

Q: (para): "What would happen if the spare failed. Do you have another one after that"

Mike Leinbach (para): "What of the spare box failed? We're not going there. The box will work perfectly."

And another:

Q:(para) "What are the rules for them for quarantine, I understand they only see one person a day...."

Mike Moses: "We lock them in a box and they never see anyone"

Almost fell over laughing...
Title: Re: SCRUB: STS-134 - LAUNCH DAY UPDATES - April 29, 2011
Post by: Ford Mustang on 05/01/2011 06:38 PM
Q&A:

Marcia Dunn -  What do you think is wrong with the LCA, and is it just an illustration of how the Shuttles are getting older?  How long has the LCA been in there?

Leinbach:  Don't know exactly what's wrong with the hybrid driver, and won't know until we send it to the malfunction building.  And no, the Shuttles are machines, and machines do break.  Nothing about getting older.

Moses:  The hybrid drivers are also fuses, sometimes fuses do pop.  We'll have to see.  Not sure how old this LCA is.


Question about effecting STS-135.

Leinbach: Rollover due the 10th, rollout on the 20th.  If we slip past the 8th, we could push that a little.  The key here is pad turnaround time.  Atlantis mission looks fine as of right now.


Question about Rep. Giffords on her travel plan and family.

Moses:  No status on her, you'll have to contact her staffers on that.  No need to keep the family in town, though, since no launch attempt in a week.


Jay Barbaree:  Any good luck scenerio for an attempt before the 8th?

Moses: Could potentially go a little earlier than the 8th, but that was hoping for Atlas to press off the range or have them have an issue.  Not a good thing to hold hope for.


Harwood for the 9th is not available, how soon is the LCA coming out, going in, why it's so complicated to retest:

Moses: 9th wouldn't be available if we went +2 on the mission, undock on the same as Soyuz.  Doesn't mean we couldn't launch on the 9th and go +1 for the mission, didn't think about it earlier as we didn't think we were heading over to that side of the range.

Leinbach: Old box out tomorrow.  New in Tuesday.  Work execution dictates the timeline, retest should be Tuesday night, Wednesday morning.  APU, ECLSS, Booster electric, Water Spray Boilers, SSMEs, OMS, Orbiter Flight Controls (and I know I missed ONE system) to retest.  If you replace the box, the systems downrange should be good to go, but our requirements are to retest those systems.  Could probably write a thesis on the individual systems in those main systems.


Mr. Pearlman: Given you have the time now, are you going to have teams look at the OMS pressure issue?

Mike Moses:  No plans to do that.  That was a creep in the regulator.  Known about that condition pre-flight.  The action we took to fix that seemed fine, no plans other than data reviews to make sure it's good to go.


Todd H: Why not undock two on the same day?  Work environment in the aft?

Moses:  Really comes down to crew work load and shifting.  Especially when it comes to both of the vehicles (Russian and Shuttle).  Soyuz would be undocking and landing in the same day, whereas Shuttle would undock and land a few days later - sleep shifting the same way.  Knowing where we stand, the two sleep shifts could phase in different directions, could be a problem in itself, without Shuttle helping.

Leinbach:  The box in the aft is just inside the door, avionics bay 5.  Access is good.  Could work with the entry platform and one below that.  But have to retest, so have to have all platforms.  When we close out, it's the same as a nominal closeout.  Work isn't that bad.


Question from Houston Public Radio:  Can you describe the normal function for this box downstream, in laymens terms?

Moses:  In your house, it's not the primary fusebox on the outside, but it's the same as a breakout box in your laundry room or your garage.  It's an aft load control assembly, there's 3 in the aft compartment.  One good way to think about this is a lot of these components are redundant, and most have two redundancies.  We're about to disconnect one of the power redundancies.  Have to retest the systems in order to see that they are seeing power from both "panels".  Have to test the bulb at the end in order to make sure the panel works.  The APU heaters are one of maybe 70 or 80 systems that run through this box.  A lot of things besides these APUs go through there.  We do know how to test the APU again now.


USA Today - Any sense about when the astronauts come back and what they are doing now?

Moses:  We will reset and start a new countdown.  Crew will come back on the normal time before a launch.  It will be a cut and dry this is a new target date.  Just not ready to make that decision today.  Crew is going back into training, but still in quarantine back in Houston.  Teams are working to have some ascent sim training on Monday or Tuesday just to refresh themselves.  We give them "free time" but they're always dedicated and checking timelines and checklists.


Ken Kremer - A little about the testing before flight?  Same problem on STS-70?  If the replacement fails?

Leinbach:  Testing leading up to is a lot of the time on-orbit procedure.  Not every box is tested in the OPF.  Last time this box was perfect on orbit, so we didn't actually test it.  Not sure on the second part of the data.  We know we took the box out, which created the retest of those systems.  Chances are that this is not the same failure as this box.  If the replacement box fails... we're not going that way, it will work great.

Moses:  We'll check for no downstream wire damage just to make sure we don't blow a new box by just sticking it in.


Orlando Sentinel - Soyuz undocking complication, are you trying to preserve a 3 day window on the other end of the window?

Moses:  No, we're trying to protect the +2 option to the Shuttle as that's a lot of get ahead tasks for the ISS.  99% wanted to call this a 16 day mission, but had to get on orbit and check everything out first.  Will have to look at all the new math in order to make sure we can have the proper sleep shift on the crew.  Right now, launching on the 9th would be a conflict on the second added docked operation day.


Question on how far we can push this mission to not mess with 135.

Moses: Looks like the 10th is coming close to it.  No longer have multiple teams to do a lot of tasks, and that's a consequence of nearing the ending of the program.  The key will be pad turnaround.  On paper, it looks like we're okay, but if we go a few days past the 9th or the 10th, we could push it a little.


Houston Chronicle - Why do astronauts have to be on quarantine, where in Houston will they be in quarantine, one visitor per day?

Moses:  We lock them in a box and we don't let anyone see them ever again.  :)  Quarantine rules are pretty straight forward.  Need to stay away from any contagious diseases that could manifest and show up while on orbit.  Can visit with more than one person for longer per day, just have to pass quarantine limits.  If you are in primary contact with the crew, you have to show you are healthy as well.  They will be at JSC in crew quarters.  They aren't restricted and locked in the building, they can go into the trainers and NBL if they needed, just don't go home to sleep at night.


Question: Any dates between the 8th and 15th you've ruled out?  Any hybrid driver failures before?
 
Moses:  Not really, they all look good.

Leinbach:  Not sure they're the same failures, but we have had driver failures before.


Question: How big is the LCA?

Leinbach: 40 to 50 pounds.  Have to wiggle it in and attach it, have a system of rails to get it in, a lot easier to use rails than muscle it in.


Moses:  APU Heater lines can withstand a single freeze/thaw scenario, but the concern is after that, which would be an issue on the integrity of the lines after that.  Don't want to get into the freezing issue on orbit.


Question: Can you clear the lines downstream from the LCA?

Moses:  Effectively cleared the wiring outside the box by doing the thermostat test itself, but we still have to clear inside the LCA as well.  Have to confirm after we take the box out that it was inside the LCA, could be the hybrid driver or a simple solder that came apart.

And if the 9th is a +2 day conflict, the 10th would be a +1 day and DDO conflict. Unless I'm really missing something here, that would make the 11th a nominal 14day mission (which is the baseline) conflict with DDO, right? Please correct me if my math is wrong.

That's why they have the experts working in there  ;)

And if the 9th is a +2 day conflict, the 10th would be a +1 day and DDO conflict. Unless I'm really missing something here, that would make the 11th a nominal 14day mission (which is the baseline) conflict with DDO, right? Please correct me if my math is wrong.

I'm about to go listen to the full presser rebroadcast, but the notes below suggest they're keeping all options open... unless I have the context wrong.


Harwood for the 9th is not available, how soon is the LCA coming out, going in, why it's so complicated to retest:

Moses: 9th wouldn't be available if we went +2 on the mission, undock on the same as Soyuz.  Doesn't mean we couldn't launch on the 9th and go +1 for the mission, didn't think about it earlier as we didn't think we were heading over to that side of the range.

...

Question: Any dates between the 8th and 15th you've ruled out? 
 
Moses:  Not really, they all look good.

I realize this isn't a democracy, but I officially place my vote for launch NET May 11th.  That would (should) give us a nice photo op of OV-105 on orbit, DDO and Atlantis moving to the right notwithstanding.
As noted on April 29th, Space Pete, please make some calls! :)

Heh, I don't think they'd listen to me. ;)

I too hope it moves to NET May 11th, so that we can get the Soyuz flyabout with ATV present. It would really help out the STS-135 timeline to get it done on 134. But, we'll just have to wait and see.

And with that we'll put this scrub for Endeavour behind us, send her virtual get-well cards and move to the troubleshooting thread here:
