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
