Re: Envisioning the world of 2100
Musk is not "moving the engines out to the rim". SpaceX is changing the arrangement from 3x3 to an octagonal arrangement with one in the middle. The new arrangement provides a little more range of movement for the central engine to gimbal while also utilizing a more efficient thrust structure and eliminating the need for the 4 outer fairings.
Technically, they are pulling the 4 outer engines in.
Baby, you and me were never meant to be, just maybe think of me once in a while...
