SpaceX FH : Falcon Heavy Demo : Feb 6, 2018 : Discussion Thread 2

Did the roadster separate from the upper stage?

No

[spacester]

Thanks. Followup question:

Do we know for sure exactly how much delta V capability it retains?

I assume no residual LOX, but then again, maybe a little bit would remain?

And what about the dracos?

At this point... it's cold, dark and dead... a man made asteroid...
All gases vented... battery drained and froze solid...
Astronomers are reporting it's rolling or tumbling at a decent rate and is easy for them to spot...
There was never any plan to keep it alive past 12 hours or so...
It's dead... RIP...

  None. The LOX will all be boiled off.
 Only Dragons have Dracos.

Thanks, I  wanted it verified.

I cannot find that fact anywhere on the web, surprisingly even this site (I must have missed it).

Tweet from Jonathan McDowell:

I now have confirmation that the Tesla remains attached to the Falcon 2nd stage, which is being observed by asteroid experts

I guess i was thinking there would be guidance thrusters, so i now suppose it's all done by gimbling?

Edit:  Ah crud, FutureSpaceTourist posted this earlier today 
Edit2: But in the update thread, so hopefully useful here too

I'm pretty sure it has cold gas thrusters for reorienting.

Yes, both the boosters and upper stages have GN2 RCS systems, though primary pitch and yaw control are by main engine gimbal while they are burning.

Enhanced images of the higher res pics posted by SpaceX. Spot the photoshop!

Ironic that you needed Photoshop to spot the photoshop.

Not photoshop. Irfanview. All I did was apply a gamma correction. By the way, I'm not complaining about the photoshop. Just pointing out it out.

Sure, but you can assume that all pictures are processed unless you pull a .raw file off the camera. Even "unmodified" images are modified.

Even if this wasn't an artsy picture, the only question is whether it depicts reality correctly.  If it takes photo-processing to tease out the change, then the image was still accurate.

Personally I'd have been fine even if they removed a visible mount, but in this case they didn't.

So Elon Musk really is Delos D. Harriman- predicted 70 years ago by R. A. Heinlein. Read the book and see if you agree

Not an entirely flattering reference but I suspect the comparison is not meant too literally!

[BradyKenniston]

I'm not totally sure this is the right place to put this but check out this GIF from my engine shot remote camera!

Edit: Here is a lower res version until I can find a spot to put the other, higher res one that works. This lower res one worked for me when I clicked on it but if you have any problems just let me know!

Doesn't seem to work for me (neither Chrome nor Edge).

I even loaded it in QuickTime, and there was no movement.  I suspect this is not an animated GIF.

Yeah, looks like the site took the first frame and discarded the rest, despite listing it as a 40MB attachment.

[BradyKenniston]

Weird, thanks for the heads up. Let me try a different version! Give me a few minutes.

Edit: Uploaded a different, smaller res one.

[docmordrid]

Works great for me (Android 7 Chrome)
