Great aerial photo of launch table with the 'dog bones' being installed. So curious how this will all play out!

A total of 8 hold down or support clamps/arms for SH have been installed on the Orbital Launch Table.

and there are more including this one (right) with dog-bone-like structures.

Question: What exactly are "launch tables" and "dog bones" in the context of SpaceX's Super heavy-lift launch vehicle, as shown in these images? Where do they go? What do they do?

Answer 1

Launch table: That thing on which the SuperHeavy booster will stand for launching. In turn, the launch table will be on top of the orbital launch mount, this thing:

Which together make this thing on the right under that SuperHeavy booster: Image courtesy of Alamy, if you want it without watermarks you know where to buy it.

From which the stacked Starship+SuperHeavy stack will launch. Those nice tall legs give the exhaust somewhere to go, and will help to keep the dust down a bit. It also apparently voids the need for a flame trench, although Elon Musk has been heard to say "Aspiring to have no flame diverter in Boca, but this could turn out to be a mistake" Twitter 11:19 PM · Oct 7, 2020

The "DogBone" structures are the 20 clamps that support and hold down the stack before launch.
