SpaceX's Autonomous Spaceport Drone Ship Discussion Thread 2

[AJW]

So it's "Gauntlet" vs "Mews" ?!

Has someone suggested 'Mos Eisley' or 'Docking Bay 94'?

Apologies if this has been brought up already, Surely parking a rocket next to a cruise ship would require zoning? I have been trying to find something/anything on possible legislature or zoning laws so we can better get an idea of the scope. Can anyone use their googlefu to find something? My googlefu is not working today, best I found was http://www.spaceflorida.gov/docs/spaceport-ops/florida-spaceport-systems-plan-2013_final.pdf?sfvrsn=2 but does not mention Jacksonville in regards to SpaceX.

I found this also -

Also this..

This last one has me wondering though..

What would be worse than zoning would be the HOA.  Woe to them if they violate the neighborhood color scheme!

Strange. Appears the Carnaval Fascination web cams are no longer available on line.

I suggested nest but gauntlet makes more sense. Elon released his falcon which flew, eventually returning to his gauntlet. Later Elon arranged for the bird to be returned to his mews.

Looks that way to me, too.  And not just the front one, but neither are available, now.  Shame.

Both tugs still in Jacksonville port, and Fascination now heading for the mouth of the river for docking this morning.

Found another Carnival Fascination web cam feed:

Fascination is entering the river. Soon to dock beside GauntletX.

Because SpX engineers know about the Inversion issue, their grid fin flight control software should be able to compensate for it and still maintain the desired F9 attitude control capability.

  Huh?  I thought that there was no control inversion issue with grid fins (non-linear behavior yes, but still “forward”) unless there was a secondary reason, such as when the wake of the grid fins acts on another surface of the vehicle.?.  I’m definitely not authoritative enough to say that for fact but I want to swing that out there as bait to see if we can get someone with a solid background to put this to bed (or not).

I didn't follow the above discussion in detail but I can imagine that modelling the physics becomes more challenging if you want to allow flow reversal. Numerical stability requires you to use an upwind scheme, cf. http://en.m.wikipedia.org/wiki/Upwind_scheme. This is relevant both for a high fidelity model for simulation/validation and for a simplified model used by a controller and/or state estimator. Sorry if I misunderstood the question.

I was all set recording the feed woke up to find its gone THANKS for new link PhilW. And  I think we need 'Name the Barge thread" 

EDIT: Updating every minute. If you open image in separate tab and 'refresh' it updates every refresh. So this way is faster than previous 30sec or 1 min refresh rate

Nice find.

It's there!!! webcam updates every ~7 sec

Nice.
Best luck the web cam is still there when GauntletX returns with F9 secured to the deck / glove.

Here is a video from the arrival of Carnival Fascination

[Misha Vargas]

There's at least 5–6 people hangin' out, scurrying on and around the barge.

[cartman]

I can see people moving about the other ships as well, so I believe they are preparing to leave port.

There will also be a bridge view, I hope people will be there with cameras.

From the ship cam, we might see the crane work though!

Container doors are open. Prep for departure? Go Quest will need 2 move 1st, so ElsBeth III can attach to GauntletX.

Thanks, cartman.

Does anyone have the programs and ability to keep a screen capture program running to capture every frame (whether 30 s or 7s) so that we might later be able to see and analyze a departure video for ASDS, GoQuest and Elsbeth III?  Watching the prep, no. of people visible on board, etc.

I have been using a python script to capture every 7 seconds. And reddit user 'doersino' is recording and  releases mp4 and jpegs.

Stop making up your own names for things. Just stop it.

Thrusters are being tested / run up.
