7 hours 40 minutes remain until start of the webcast

Webcast is 14:30 ET (19:30 BST, 20:30 your local time).

I believe it's 03:04 ET as I type this, so 11 hours and 26 mins to start of webcast.

cheers, Martin

Do they fully fill the tanks for the static fire, or just put in the minimum to chill down everything and run the test?

Full tanks, because that is the lift off conditions.  Even the second stage will be tanked and it doesn't fire.

Full tanks, because that is the lift off conditions.  Even the second stage will be tanked and it doesn't fire.
so probably the more appropriate question would be what are the differences, if any, between the static fire conditions and launch conditions, apart from the obvious (e.g. hold down mechanisms not set for release and engines set to cut-off after 2 seconds)?

Wow, that's news to me, I thought this feature was a future upgrade. Is this the first flight with this capability?

It might if some rumors by kevin-rf (etc?) are true. I.e. that this Falcon 9 upper stage has the delta-v-kit on-board. Clarification is definitely needed, here.

No, I was responding to Corroded Nut's post, Draco's on the US would mean the Delta V kit is included. If that is incorrect or unknown, then what I said is incorrect. Chris removing them from the article means, he is not sure if they exist or not.

Both the Livestream site and SpaceX feed are glitchy and halting for me, but NASA TV is running fine.  21 minutes and counting....


I believe that is incorrect, that the second stage has no Dracos.

But there are Dracos on the Dragon capsule.  Doesn't that make more sense, that the existing Dracos on the capsule would be used for attitude control, not that extra Dracos were added to the US.  More torque applied from the capsule position as well.

Also, in the NASA TV transmission, the video frame is significantly cropped, but only in the horizontal.  You can't see the red "Live" bug in the upper left corner at all.  I estimate about 6% is lopped off each side; top and bottom are also cropped but just barely.

This is why we do static fire tests...

(I believe they have the ability to recycle and do it again today, like they did in other flights. Can't do that on launch day because of instantaneous window, so good that they're getting the bugs worked out now.)

A rule of thumb: if you see the vehicle starting to vent again after around T-40 sec, it's a safe bet the count was aborted.

That's safe to assume, but even if they started draining prop immediately, it would still vent for many minutes afterward.

I'm guessing here, but one WDR recycle was due to something related to a 2nd stage vent which might have also occured at roughly this point in time. Or not.

Yes tests are scheduled for specific times so that everyone is on the same page.
But if they need more time, as they might, the question was, since the rocket is sitting there fueled, and no one else is using the range and no one else is launching today, for what reason would they not be given an extension?


Edit:  Thanks Antares

Hi-res mission control pic from Elon's twitter: https://twitter.com/#!/elonmusk/status/197049032286281729/photo/1/large (https://twitter.com/#!/elonmusk/status/197049032286281729/photo/1/large)

That would be launch control center if it is at the Cape.
I think that's in California. It looks like the control room Elon showed recently in a tour of their control center in Hawthorne (where Elon also said he'd be in California for the COTS 2+ launch).

Yes tests are scheduled for specific times so that everyone is on the same page.
But if they need more time, as they might, the question was, since the rocket is sitting there fueled, and no one else is using the range and no one else is launching today, for what reason would they not be given an extension?


Other people have lives and plans.  The range is basically a one shift operation.  It can work other shifts but with preplanning.

No, it was an overly-restrictive condition that had nothing to do with main stage propulsion, so it would probably have been fine.

For the record, I'm seeing a 19 second lag on the SpaceX webcast, assuming that the T- clock is aiming for exactly 3:00:00.  The NASA TV retransmission is another 5 seconds back.

Stream is still lagging reality by about 19-20 seconds, but now the NASA TV retransmit is about 38-40 seconds back from the stream, and periodically goes to a low res version, while the stream stays high res.

On a related note- can we presume continued venting means no prop offload so far, so not aborted *yet*?

That's safe to assume, but even if they started draining prop immediately, it would still vent for many minutes afterward.

I think the first four words of that sentence are contradicted by the rest of it.

Looked good to me, don't know if it was for the full duration. I did see a reddish-brownish cloud, like you see for nitric acid-based rockets... is that from the hypergolic igniter?

Nah, just smoke looking browner than all the water vapor, coupled with the camera white balance setting.

TEA-TEB hypergolic igniters, according to another site.

I know what they're using, I'm saying that's a lot of smoke to be produced by the small quantity of TEA/TEB used during ignition. On the other hand there's a whole lot of black smoke and soot released when Merlins shut down.

Right, I had forgotten if those TEA-TEB igniters were based (heh) on nitric acid or not. They aren't. And, as you said, it's probably too little to make that sort of effect. It's just the hot brown smoke from kerolox combustion.

Also, doesn't TEA/TEB give a green flame?

Yes, but doesn't mean the smoke is green. IIRC, the smoke was bluish-white.

Ah, of course, the colour of the flame has nothing to do with the colour of the smoke.

This ISS update video shows another view of the static fire, from a distance. Seems to have been ripped off from Ustream judging by the framerate.

Frame rate looks fine to me. The long camera-to-rocket distance coupled with rising hot air is distorting the image.

Frame rate is at most half of normal, 30 fps for NTSC video. Trust me.

After the static fire would they offload the hypergols or leave them in the Dragon?

The hypergols weren't loaded just for the static fire, they put on board for the flight.

There would have to be, due to the (usually) corrosive nature of these types of propellants.

The DragonLab datasheet lists "Mission Duration: 1 week to 2 years", so doesn't that imply that the systems are designed for long-term storage of hypergols? (Though, I could understand if that wasn't fully developed for these early flights).

Edit: is there anything different about lifetime in orbit compared to lifetime on the ground?

I thought the same thing, but was wondering if there were some safety/workplace rules that would necessitate defueling Dragon at some point.

Thanks for the picture corrodedNut.

I'm curious why the ladder on the strong back is located where it is.
There seems no need to go higher yet a need to go from the bottom of the ladder to the top.  ???

I think the bottom of the ladder is as high as the cherry picker can go.

For me it says that the video is encoded at 25 fps and I can set it to HD (1280x720). However, there's also a "stage frame rate" which is the frame rate of the player (Flash Player in this case). In my case it says "10 stage fps". So it seems that the slow frame rate stems from the player. I downloaded the video as an MP4 file and I get the 25 fps rate.

I hope we're still talking about the same video ("[SpaceX] Static Fire Update from ISS Mission Control")

Sigh. The fact there are N frames per second encoded in the video does not mean there are N unique frames. For example, I can easily generate a 30 fps video which duplicates every frame and thus has an effective frame rate of only 15 fps.

I don't have to look past the actual video to see it's not full motion and if you were shown the original footage side by side, you'd notice it too. NASA's Ustream channel does not webcast at full framerate, whereas the old NASA Windows Media streams did. They made a step back in my opinion.

While this is technically correct (assuming you mean 29.97fps and not 30fps), it is not how most of the SpaceX sources nor encoders work. If you're not seeing 25fps+ video, then you have an issue in decoding the stream. Try enabling/disabling your GPU acceleration in flash. The SpaceX stream is also MBR now, so you may want to try a lower quality if your system can't keep up for some reason. The player is supposed to automagically select the right stream for you, but if you're right on the cusp it may pick incorrectly. Having the latest version of flash always helps as they keep fixing issues with the stage and GPU offloading.

A very recent change was made to get the HD video more fluid and closer to 29.97fps rather than 24/25fps for launch itself. 60fps (59.94) is a bit excessive for web video. It would be cool, but the playback requirements go too high for most users. Same with 1080p unfortunately.

And here's a niffty little tip I'm not sure everyone knows... There is DVR now ;)

It's definitely not that. I've tried everything from lowering quality to lowest, playing it offline with other decoders, to checking out other recorded sources (including NASA's forwarded webstream) and they all "stutter" at identical timestamps indicating this is really present in the stream going out of Hawthorne (?).

This, I *think* is the crux of the matter. If you were doing this, decimating 30 fps (OK, 29.97 source video) by a non-integral factor (i.e. everything other than 15 fps, 10 fps) you're bound to run into this kind of skipping. To some people it's not noticeable, but to others the motion discontinuities are among the most annoying video artifacts there are.

Lest I only be criticizing the webcast, I will say that the image sharpness was noticeably better than on the previous launch and pad camera aspect ratios were good.

Oh, I definitely agree. While it would make engine plumes dance around more happily, it's definitely overkill for everything else including player performance requirements.

Yep, and it's a very cool feature. Something I haven't seen with any other launch webcasts yet so kudos for implementing it.

Agreed - very cool.

Used it myself, but it wouldn't let me wind back once the broadcast finished. I don't know, but wonder whether it would have cut me off if I'd been chasing at that point.

I agree.  Thanks!

The solar panel pontoons are not lined up with the strongback, the base of the rocket, or with the Dragon capsule.  This is a bit of unusual asymmetry.  My guess would be that the solar panel anchors / roll joints are on the "centerline" and the panels extend from there.  Perhaps the panel closest to the second stage is not "half sized" as depicted, or perhaps the half sized panels and the hinge together are as wide as a full panel, displacing the center.   I look forward to seeing images of them deploying (I hope) and deployed.
