Good call moving this to the discussion area mods.

I did before I posted. No further evidence was given.

That's why I posted that it was claimed to be moving there. I shouldn't have done it in the update thread though.

Any ideas what is happening? Maybe this is an old one from the landing pad to LC-39A?

The rocket is still dirty and it is posted by someone who's only other post was one asking if they had been banned. I think this is just an old picture of it going to LC39A that someone reposted for the hell of it.

I would tend to agree, however, I don't see the crane fixture on interstage. We may just not be able to see it though. Was there any additional maneuvering of the stage after the initial video/images we saw?

You expected them to wash it inside the LC-39A hangar?

Looks like they got the speed at landing just right!

One interesting thing about the new video is that it shows the landing burn ignition... For just a frame there you can see the green light inside the center engine from the TEA/TEB ignition. (at 2m 35sec of the video)

new video just posted...

very little on-board footage from the landing though - just a few seconds of the boostback burn. some new nice closeups of the actual landing.

Does the stage start to go UP again just slightly near touchdown? (around the 2:53 point)

Yeas, just slightly. Future landings will no doubt have parameters tweaked.

Yes, and remember that the white residue on the two other engines suggests they inject TEA/TEB into all 3 engines for plumbing & control simplicity at all three restart events (boostback, re-entry, landing) even though only center engine restarts for landing.

So we may be seeing a "3 engine" TEA/TEB flash there.

Found a good gif of this on reddit.

Anyone know what this little doohickey is?

I believe its more likely that the landing "legs" slight rebound after contact and weight transfer making it look like its going up is what you are seeing there.

GoPro mounting point sans fairing, maybe? That little black dot below it looks way too familiar.

Looks like the mounting bracket for an N2 thruster pod. However that picture isn't the F9 from the ORBCOMM-2 launch, since this picture has fairings around the grid fin mounts.

That's where the thruster pods are now in the Full Thrust F9, but as you rightly observed, the photo is from a pre-OG2 launch when the thrusters were still up near the fwd end of the interstage, out of frame of this photo.

Looks like the first stage is on the move:
https://www.reddit.com/r/spacex/comments/40naon/landed_falcon_9_rolling_to_slc40/

looks to me like theyre just storing outside (temporarily?).

no sign of a transporter erector

can see the rings at either end for supporting and rotating the stage horizontally

Chris Bergin · « **Reply #2157 on:** 01/12/2016 10:11 pm »

Yeah, had it confirmed (I asked) it's going to SLC-40. We're not sure why they opted against the original plan for 39A.

Dante80 · « **Reply #2158 on:** 01/12/2016 10:40 pm »

This is somewhat weird, I thought that SLC-40 was to launch SES9. We haven't heard anything from that campaign yet (aside from a Jan23 date somewhere that got taken out now), but I would assume they would start working on it pretty soon.

Can the HIF accommodate two cores?

rocx · « **Reply #2159 on:** 01/12/2016 10:48 pm »

Worst case scenario: a problem has been discovered at LC-39A that prevents holding a static fire there for the near future.
Best case scenario: SpaceX is planning to refly this core sooner that we think.
