Any idea when the FD2 Execute Packages will be up? I know it's early but I'm having problems finding them on the shuttle site. Link?
Is it just me or do they wait until FD3 before they post them all?
Thanks.
-
It's going to be interesting seeing the SRMS and OBSS work together around the P3/4 truss. I know it won't get in the way but the clearances are going be tight I'm sure at some points.
-
tiger: They usually weren't up until well after crew wake-up if I recall correctly from 121..

Where are we with Fuel Cell 1? Is it running with the pump motor only on two phases still?

Time for the Wake Up Call...
Moonriver???
LOL!! I think I would hit the snooze button if I had to wake up to that song!!

- Ed Kyle
Yes, they've been running the pump on 2-phase (apparently it's qualified for 2-phase use as a contingency mode).
I think I read that they were requested to re-enable the phase-1 breaker (from off to on) just before crew sleep. Probably a test, but even if phase-1 is still out, they have more than enough time to take the breaker off after wake-up before loss of the pump can cause problems.
-
This is awesome! the crew has allowed us to come onboard and see. You can see the picture now.
Too bad the signal blows. Hope they will keep the camera on for the next pass.
Edit: It looks like its somthing with the camera or what its hooked up to as that camera in the bay looks just fine.
-
Short time/pass for on board video, apparently.
-
So, is NASA saying 115 is an early Christmas present? :) ;)
-
Good NC Burn!
-
Y'know, as long as I've been following Shuttle flights (many years), I've never been worried about OMS operations or burn successes. Probably because they've always been highly reliable and Mission Control knows what they're doing in planning the major burn attitudes and lengths, as well as the health of the OMS systems.

STS-115 Execute Packages

Cool, thx!
Flt day 3 (approach, docking, unbearthing/handoff) looks like it's going to really be a bear, though. And 2 consecutive EVAs on top of that, in the following 2 days.
(As much as I'd love to be where they are right now, I don't envy them the workload and "stuff" they have plans to get accomplished before undocking)
-
Who is the CAPCOM lady on this orbit team?
Megan ...something?

Yes Brent Jett used to call that an 'agressive timeline'. I very much like the expression ;-)

Liked that overview of the crew just then. Almost up to Arianespace Ariane 5 ECA quality presentation (the best by far). Those that watch the Ariane 5 ECA launches will know how slick they open up.

Some might say that the smooth Ariane 5 show is always the same. Only the name of the satellite companies change.

Wow, didn't get to hear it, but if they're playing Andy Williams for wakeup music it's much easier to go back to sleep. ;)

Anyone see any problems via the scans so far? Looks a very clean Atlantis.
And on the Ariane TV, Jean Michel Jarre had involvement, which is why it's so good.

Hardly any debris came off the ET so I would be surprised if they found anything.

Well, sure :), but private enterprise can usually be more 'in tune' with viewers' expectations and likes than a typical gov't bureaucracy.
I've always been impressed with the Ariane launch commentators and launch production telecasts.

Yep. Chips and Gap Fillers will be what we should keep an eye out for.

What's the 'force fight' issue with the speed brake noted in FD02 execute package?
-
Chris Bergin - 10/9/2006 1:34 PM
Yep. Chips and Gap Fillers will be what we should keep an eye out for.
Speaking of gap fillers, I think I saw something that looked like two gap fillers during the starboard wing scan, around where the ET umbilical wells are.
-
Force fight: each channel of the flight control electronics drives a hydraulic channel and they are mechanically summed - if one channel goes wrong and tries to command the speedbrake the opposite way to the others you get a force fight (3 against 1, I think - assuming there are 4 channels for the speedbrake).
I imagine they could just shut down channel 3 for entry if it still misbehaves.
Edit: worth saying that this is how the redundant set of 4 PASS computers commands - the "strings" are the independent paths from the GPCs to the hydraulic actuators (with several things between) if one goes wrong the others can still win the forcefight.
Caveat: I'm a handbook reader, not an expert! Others can probably give more accurate explanations.
-
cabbage - 10/9/2006 7:45 AM
I imagine they could just shut down channel 3 for entry if it still misbehaves.
That's what the execute package says in the workaround:
A bypass of Speedbrake channel 3 will keep the problem from generating a force fight and may be required for Entry.
-
Ok, maybe the launch wasn't as trouble-free as I thought yesterday, there was an issue with the Speedbrake that I missed. Here is the list of current failures for FD 2 from the Execute Package, tidied up with my understanding of the meaning. Can 'those who know' correct it where I have, inevitably, messed up. Posted for info for those who don't want to or can't download and wade through the package and to check my own understanding.
Version 2
a) SYSTEM
b) FAILURE
c) IMPACT
d) WORK AROUND
e) My understanding
a) APU
b) APU 3 EGT 2 was erratic during APU operation.
c) None.
d) None. APU 3 EGT 1 is available on BFS SM SYS SUMM 2.
e) I presume EGT is Exhaust Gas Temperature, as per aviation usage. In any case they have what looks like a failed sensor on APU 3 but will switch to the redundant sensor
a) EPS
b) Loss of Fuel Cell 1 coolant pump Phase A.
c) Loss of redundancy on Fuel Cell 1.
d) Fuel Cell 1 Phase A sensor is unpowered with the cb open. L4:C cb AC1 FC1 PUMPS Phase A was opened to protect against further damage and will remain open. If AC1 Phase B or Phase C is lost, Fuel Cell 1 shutdown will be required.
e) (Previously known issue) They are still operating with Phase A on the Fuel Cell 1 coolant pump disbled (ie. 2 phase). If another phase fails then they will have to shut the FC down and shorten the mission.
a) GNC
b) Speedbrake Ch 3 transient degradation of driver output. The momentary degradation of driver outputs generated a force fight several times during ascent and after powered flight.
c) Speedbrake Ch 3 is considered failed for mission duration. The root cause of the problem is not known, and the rest of the actuators on ASA 3 have not been exonerated.
d) A bypass of Speedbrake Ch 3 will keep the problem from generating a force fight and may be required for Entry.
e) There is a failure on one of the redundant flight control circuits for the Speedbrake (Split rudder) that makes it physically fight the other three channels. This may be common to other actuators on that channel(?). The appropriate channels control of the Speedbrake has been cut and will probably remain so for entry.
a) PLBD 1
b) Stbd Dr Aft Close microsw failed on.
c) Stbd Dr will close single motor.
d) None. Mech SSR-6 available to regain motor 2 drive if needed.
e) The Aft section of Payload Bay Door 1 (Starboard / Right) had a microswitch failure that means one of its two motors will not be available for closure. (The switch is telling the system that the door is already closed) It can be closed on a single motor but there is a procedure to work round the microswitch to reactivate the motor.
a) PLBD 2
b) Port Dr Fwd Close microsw went off prematurely.
c) PBD CONFIG msg during opening.
d) None. MANUAL mode necessary for door closure if microsw not regained using AUTO mode.
e) The Forward section of Payload Bay Door 2 (Port / Left) had a microswitch failure that indicated the door was open before it should have. Manual control may be required when closing this door.
Summary added by SBT MExPkg
a) FES
e) Water in the common ducts from recent rains caused an issue with both Flash Evaporator Systems. The result was a drop in temperatures in the Hi Load Ducts (anybody care to explain what there are) prior to the systems being switched on at SRB separation. The Hi Load Duct heaters had to be switched on to prevent ice formation. This is a known issue that has been seen before. The temperature had, however, not stabilised after this procedure sufficiently at FES activation and the FES system automatically shut itself down. Cycling the systems off and then on caused a 'restart' at a point where the temperatures were stable. No further problems were encountered. The FES are used to cool the Orbiter prior to the Radiators on the inside of the Payload Bay Doors being exposed when the doors are opened.

The fuel cell issue was known -- that's what stopped them from launch attempts on Wednesday and Thursday to troubleshoot.
Also, the execute package has some extra detail on the issue with the FES during ascent that they see from time to time.

The intended audience for the execute packages is the crew and they are probably posted publicly due to news media request. I'm happy to see them, and anyone can read them, but it doesn't matter to the publisher of this material if anyone outside the intended audience understands.
(It's PAO's problem. :) )

I should have made myself clear again...
I was referring to the reader of my post, not that of the original MEP, whose purpose and intended audience I understand (and hence why we won't see one for Day 3 until it written at the end of Day 2).
For folks that don't, here is my understanding. They are a list of updates to existing plans and documents held aboard the shuttle. Its so large in part due to NASA generally[1] sending whole replacement document sections rather than individual pages or single line change requests to keep things simple for the crew and because many changes involve wholesale revisions to plans.
The Mission Summary which contains an updated set of abort options, system status etc. is stand alone, it updates nothing, it is the Mission Summary for the relevant day.
The alternative is to, for small items that are known to require a 'last minute' update, to have a fill-in box on the procedures. You can hear this in progress when the Commander fills in items such as Barometric Pressure and Abort parameters read to him by the CAPCOM just before launch.
[1] There is one example of a 'single line change' in todays MEP.

No problem, Rick -- I didn't finish my thought, either, which is this: I don't want to clutter up the threads, so I'd rather wait for someone to ask for an explanation than to presuppose that someone will ask.
There are lots of things going on and while I have some open questions, I also don't want to lose track of the real-time events.
Just my opinion.

I've been watching the port wing RCC inspection, during the center pass (step 4 I believe)
I noticed what looked to be a chip on the T-Seal between panel 8 and 9.
Did anybody catch this or is it a reflection or bird poop again?

Whilst this post goes against that (last one, I promise!) I agree with those sentiments, whilst we can just about get away with this discussion during a 'quiet' phase today Day 3 is going to be hectic (although I will be at work :( ) and exchanges such as these will have to be clamped down on.
May I suggest that Day 3 has two threads, 'Discusion' and 'Events' so background info, questions etc. can still be asked and answered.
My intent in the 'Issues' post was to cut down on the 'how is X doing' posts and the almost inevitable multiple answers. IMHO one big post is less disruptive than many small ones. Perhaps someone else could do something similar tomorrow on the 'Discussion' thread.

Does anybody know the last name of the PAO officer at the mission status briefing, John ... ?

FWIW, a short post Orbit 1 shift status briefing -- nothing to report in terms of analysis of the inspection data yet. Paul Dye provided explanations of some of the items in the execute package.

Kevin Chilton put it real well back in 1994. He said "they advertise waterbeds as being so comfortable because there are almost no pressure points. Well in Zero G there are ABSOLUTELY no pressure points. So it's very easy to find a comfortable position and just doze off." Plus I imagine as busy as they are during their 16 hour work days it's not hard to just pass out.

I would have a hard time falling asleep in zero g. Everytime I dream I'm falling I wake up with a start here on earth. I've read that being in 0 g feels like hanging by your knees with your head down. Would be nice if we had some astronauts here to explain the feeling of spaceflight.
-
Anybody know what the issue is w/ the cabin feed having a horizontal black line? The line slowsly scrolls vertically (i.e. it creeps up the screen) and has white dashes of various lengths (reminded me initially of morse code, dit-dash!)
I seem to recall seeing this during STS-121 and the explanation being something about TDRS-Z not working so well. Could be wrong though, and my searches of the forum archives didn't turn up anything...
-
I've seen that from time to time. I imagine it's something with the camcorder or the cables controlling the camcorder. I wouldn't think it's TDRS because there are plenty of other video sources from the shuttle and station that look perfectly fine.

b) Speedbrake Ch 3 transient degradation of driver output. The momentary degradation of driver outputs generated a force fight several times during ascent and after powered flight.
Rick
On reading this some questions came up:
- why are the speedbrake actuators operating at all during powered flight? Is the speedbrake used in the early launch phase for roll control?
- and why would the speedbrake actuators be moving *after* powered flight? Or would that be to move the brake to the center position?
Thanks,
GJ

The speed brake/thrust controllers serve two distinct functions: during ascent, the pilot's speed brake/thrust controller may be used to vary the thrust level of the three SSMEs. During entry, the commander's or pilot's speed brake/thrust controller may be used to control aerodynamic drag (hence airspeed) by opening or closing the speed brake.

Manual throttling is not done normally during ascent; it's likely not related to the reported problem.

I don't think the pilot would do this manualy but since he can the system would have been tested before launch. I don't know when the speedbrake became an issue?

John Shannon showed a few of the ET umbilical camera images -- I assume these will be (or are) posted online by NASA. Two or three partial pieces of ice-frost ramps were shown and another little bit in the area where the LH2 PAL ramp was removed from this tank.

The point is that the issue is not related to the CDR or PLT hand controllers; John Shannon reported that it appears to be an electrical issue in that control channel.

Since the hand controllers don't position the speed brake during powered flight (the flight control system is doing that automatically), that couldn't be the answer, though.

And the rest! There's so much on there. NASA really do put a lot of effort into every inch of a mission, really is great to see with the amount of depth in that above presentation and all the other stuff that was added on top.

Looks like a lot of FD3 activity is going to happen overnight :( for us folks on the US East Coast... Keep good notes on the FD3 page for me..
And just to keep this note newsworthy... The wake-up calls audio are buried on nasa.gov... Here is a direct link if you like to listen to them like I do.. Should work for the rest of the mission. Moon River was a bust IMO but hopefully Brent Jett liked it..

I heard they saw some red discoloration on the OMS pod believed to be hydraulic fluid. Any further word on that from anyone?

Ironically, they probably saw it here. Certainly wasn't reported anywhere else that I saw four hours ago when that article went on site. Anyway, we should all go to the FD3 thread.
