To fuel our future in space, we will need massive industrial production up in space,

but how will that develop, and will the creation of such industries to help colonize space

also influence how and where that colonization occurs?

No. influence how and where that colonization occurs. We've recently been discussing the development of industry on the moon and how that might serve as a base for expansion into

the solar system and beyond.

Today I thought we might look at how various regions of the solar system might develop

industrially, so we'll be looking at how space around the Earth and Moon might develop,

and what directions we might go in for the asteroid belt, Mercury, Mars, and Jupiter as well.

Indeed we'll move out not

just the Kuiper belt and Earth Cloud, but also takes some time near the end to look

at this notion at the galactic level.

Industrialization of space is a peculiar thing, since so much space pioneering speculation

and science fiction focuses on Mars and other off-world colonies, but in truth I'd rather

expect words like Mars to be fairly minor player in a developing solar economy, and I'd also

expect the space right around Earth to be where the supermajority of industrial development and

colonization occurs for many centuries to come. It's commonplace to imagine humanity numbering a trillion people spread over many worlds

and many systems within the next few millennia, but I don't think we'd really be all
