industrial base in space

there is little to no commercial demand for an industrial base in space 

but in the future

if various militaries wants to build fleets of interplanetary spacecraft 

and autonomous robotic bases on other planets 

and if various space agencies wants to build research projects in space 

and on other planets 

and if companies wants to build large space stations 

and transport spacecraft in space 

then that will increase the commercial demand 

for an industrial base in space 

industrial components could be constructed on earth 

and transported with reusable large rockets to the moon 

where those industrial components would be assembled 

into factories on the moon 

and those lunar factories would use moon dust 

which is rich in silicon, various metals and oxygen 

to produce industrial components that are transported into space 

and assembled into factories in space 

then those factories would be pushed by rockets to the asteroid belt 

and mine asteroids which are rich in a multitude of materials 

then those factories would produce industrial components 

which would be assembled into factories in the asteroid belt 

and transported to other asteroids in the asteroid belt 

all these processes would be autonomous 

with the use of ai, robotics 

and remotely controlled and monitored by humans on earth 

the processes would repeat itself until the market demand is met
