and i don't know about rocket mechanics. what kind of

engines and amount of fuel in what size that determines

landing on exact location from orbit.

 

is direction more important at that altitude,

or the constant boosters working to get there

through the atmosphere?

 

i have no idea. but mr musk would know.

 

and i hope, it can be a far smaller, economic size.

 

quantity and precision (tracking) is the key.
