Buried in one of the old ASDS threads, no doubt.Or ASDS is maintaining predetermined position as well as orientation? What factor decides what orientation ASDS should maintain? Is it something related to waves like aligning to have them along length than width. That's a good question. And a complicated one. Boats sitting still act nothing like boats moving. Bow into the waves on a still barge could make the thing pitch more than side to the waves. And, do they worry more about pitching and rolling or sliding sideways? Those Thrustmasters aren't instantaneous.

I think when when the stage comes in close to it's final resting place, it will be on the drone ship, not a truck.They have experience of trucking the stage for thousand of km, they never experienced vertical barge transport.That said, I don't put a dime on a JAX stop.

There is an outstanding $20 bet between Elon and someone about whether the stage will fit under that bridge.
The barge sways A LOT, definitely more than 10 degrees, but the stage seems pretty stable, no signs of movement, which is impressive. Looked close to 20 degrees.
I noticed that the RCS thrusters are still firing after the stage is landed
If it were keeping the stage upright and stable, how long would the RCS system be able to sustain this (i.e. in strong winds/waves)?
A non-trivially off-center landing. I think we will see somewhat bigger barges in the future.

Maybe sometime they will tweak the landing software to "lead" the targeted landing spot to be a few feet upwind of center, so the descent will be "over" that upwind spot and try to land a few feet upwind, but when it levels out to point vertically, the wind will push it closer to the center. Of course if it really was 50 mph wind.... then it works without the need for doing that. But inevitably there'd be some day with even higher wind, where such a landing software tweak might allow it to land safely without drifting too far and put a leg over the side, leading to it falling overboard.

The rocket isn't going to change in real time but the barge can do a readjustment and the wind measurement tools are right there.

Can someone provide a picture of anything more definitive?Do you mean this shot?It started with a photo Ohsin attached at 4:58pm yesterday and then I embedded it, again below. There's a hazy outline or two and a light in the background to the right, but clearer in this shot than in Bargemanos'.

We saw the support ship approaching the ASDS soon after the landing.

IMHO, the forward blast wall top is in line with the horizon, so in that area you're looking over the top of the blast wall, and the things we see there are IMHO parts of OCISLY; the generator exhaust stacks, and, I think, the satcom dome.

Gosh I'm sorry. CJ is obviously correct. My statement was wrong.But it was a minor point. The ship is somewhere maybe an hour or two away. The basic conclusion remains. The first stage was probably secured within hours of landing.
