Does anyone know why SpaceX rockets are moved to the launch site in a horizontal position, then raised to a vertical position, instead of the way NASA does it, which is to move the rocket to the site in a vertical position.
I've searched for an answer, but found none.
I don't know, Wild guess, perhaps they realized that they could save money if they moved it faster (less turnaround time) and in the horizontal position they would be able to move it faster - significantly less wind resistance and no worries about it tipping over from inertia when it starts or stops either.
Whatever the reason, if any public discussion board would have the answer, this one should, so I look forward to finding out!
That sounds like a good guess Sean.
