SpaceX Falcon 9 v1.1/Thaicom-6 Pad Thai Party Thread

[Lar]

I love how they say MECO-"1". Can't wait for them to start broadcasting the next 2 MECO events as well as Legs Deploying...Confirm Legs Deployed...1st Stage Touchdown etc...(Not in that order)

Well I kind of HOPE that's the order... because "first stage touchdown" ... "deploying legs" would be a Bad Day for recovery of that stage!

[Rhyshaelkan]

Taking far too long to tweet an one-liner. Spacecraft sep should have been already over ten minutes ago.

Don't think everything went nominally 

This should be a lesson for most of us to chill out a bit. The absence of notification of an event is not evidence that the event did not occur.

If a spacecraft deployed in orbit, and there was no one around to tweet about it. Did it really happen?

Does anybody know anything about the Payload Processing Facility mentioned at 9:20 in the video?

[cartman]

Does this video show that there is about 20 seconds of delay for the webcast?

Does this video show that there is about 20 seconds of delay for the webcast?

Yes, in that case. But due to network routing and buffering differences, it won't be the same delay for everyone.

That appears to be the SMAB (Solid Motor Assembly Building).

Yes, in that case. But due to network routing and buffering differences, it won't be the same delay for everyone.

So, is it reasonable to speculate that a large part of that delay is SpaceX induced, so that they have time to cut the stream before something bad is shown?

Very nice...


And... umm.... I'd totally "at girls who wear..." :blush:

No. Theses kinds of delays are the norm for streaming.

Correct, but SpaceX does also have a delay built in to cut off the broadcast prior to transmitting images of a failure, which it has used in the past.

There is a difference between having a kill switch in a live feed (everyone has) versus having a significant buffer to prevent even last the couple of seconds before an incident to show up. (which would explain part of the live stream lag) When have we seen the latter?

Falcon 1 Flight 3 was the most pronounced use of the delay kill, where images showed things going well even as sounds of a crowd reacting to the stage recontact failure could be heard in the background.  Video from the rocket was cut off before the failure was webcast.  We still haven't seen it.  The first two Falcon 1 launches and the end of the fifth Falcon 9 launch also saw abrupt webcast terminations.

 - Ed Kyle

The onboard video of the failure, including stage separation, the recontact with the second stage, and then the kestrel engine igntion while still inside the interstage, is on youtube and has been for a while, failure is at about 2:50.

Interesting: the old onboard video from Falcon1  has much better quality than nowadays - f.e. Thaicom6...

IMHO it is not reasonable to speculate that, no.  The delay grows until you refresh the feed.

Highly dubious of that.

This needs to be taken to a different thread, but...

For reference, here is a what appears to be a recording of the webcast. No hint that the audience sees the problem before the video, even though the video is ended before the separation is shown:

That Falcon 1 Flight 3 video is a blast from the past.  I remember it well.  It was such a dissapointment.  Thank you for linking to it again.

Sort of miss Max Vosoff and his commentary.  I see that his NOFBX payload for the SpX Dragon trunk has been demanifested.

One thing quite prominent in the Falcon 1 video is the roll rocking as the turbine exhaust is tipped to counteract it.  Roll control is so much tighter on the Falcon 9.

The video may appear to be of higher quality simply because the lighting is so much better.  Falcon 1 flew pretty much right at the Sun under clear skies, instead of flying with the Sun in the back-looking field of view under very cloudy skies. (Apple fans may note the QuickTime logo and credit that for the high quality.)

A lesson not learned is that SpaceX needs RainX on their camera windows.  It would do a world of good in helping the water bead up.

And the complaints about the video lag and synchronizatin errors are becoming undignified.  My request is, having heard them time and again, with no real evidence of anything other than technical imperfection, is for people to let it go and move on.

[kevin-rf]

I especially liked the play of colors with the lighting and clouds at the start of the launch. The colors make it one of the most awe inspiring launch webcasts I have watched. Think they bribed someone that runs HARP to get that combination of perfect weather, lighting, and clouds?

More than likely SpaceX got the old Satellite Processing and Integration Facility (SPIF)
