I am sure SpaceX will find a place for the Grasshopper cowboy on BFH. Maybe peeping out of one of those portholes?

 Three years of very little out here, and in a month, this is the view walking back from the beach.
 They're burying lots of electrical conduit at the pad.
 It's a tad hazy today.

Those who danced were thought to be quite insane by those who couldn't hear the music.

There has been discussion about how to get the hopper from there to here. At this point I would not be surprised if they put roller skates on the fins and Elon tows it down the road with his Tesla. :o

Online Inoeth

in all seriousness there is the road that goes directly from the tent the Starhopper is being built at to the launch pad... I imagine they'll lift the whole thing onto a massive flat bed truck? If they use the entire road there should be enough space on the side of the road to deal with the reach of the legs (prob just temporarily remove some signs)... The real question in my mind is how will the rocket be placed on the truck since the legs are to big to be the thing on the truck so IMO i think they'll remove the engines and put the rocket on the bed of the truck not unlike when it was on the 'water tower' base that we originally thought it was...

Occam's Razor.  They'll have some frame or beams onto which the base can sit with the engines in place.  You don't set anything of this magnitude directly on a flatbed so whatever you do set it on will accommodate the engines without need of removal.

Glad about the activity at the pad, which may become the critical path to launch. In a Jan 5th tweet on when the BFH would launch, Elon replied "Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issues".
Of course this is Elon time so multiplying by 3 would give give 24 weeks which is probably about right to get the pad facilities built and commissioned including the LNG and LOX tanks plus required utilities. So the first launch is July 4th?

Methink the SX CTO have watch too much of Gerry Anderson's Thunderbird TV series for inspirations.

All we need to complete Thunderbirds vision is a line of palm trees on horizontal pivot mechanisms along HWY 4.

Those are off highway 4 about a mile and a half from the control center.
 One bit of good news, they put that piece of junk they installed two years ago and never used back on the trailer.

The DC-X was amazing.   It's surprising and disappointing that no one continued that line of design and thinking until Elon came along.

If memory serves, the New Shepherd does have some DC-X heritage.

That discussion of VTVL rockets is not about Boca Chica, so I deleted my response and moved it
here

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

I wonder how big (or small) the BFH looks from the viewing area on South Padre Island. I bet they are excited to see something flying this year.

Sounds like they are pouring the cement for the pad today!

Nit clarification on a personal pet-peeve.

The statement above is like saying:  "... they are pouring eggs for the cake today!"

cement : concrete : pad :: eggs : batter : cake

How long did it take for the other concrete cakes pads of SpaceX to be layed down and cured to the useable state? Given that the concrete should not be super thick, less than two weeks would be my guess?

I don't know the answer to that specific question but when the issue of concrete cure came up recently, I did some sluething.

Depending on whether they need an Ultra-High Compression Strength Concrete they might not need a full standard 30-day-ish cure.  Concrete specifications can be created to deliver a target compression strength at 1-, 3-, 5-, 7-, 14-, 28-days or whatever is required.  Only exception would be if they were at the absolute limit (or close) of what concrete mixes can deliver.

As an aside, IIRC the thickness isn't as important to cure time as it might seem on the surface.  It does play into a concrete cure due to temperatures and such but in general, cure is a factor of chemical process that occur within the pour mostly unrelated to thickness.  I'm sure an expert can articulate that better.
