'''Advantages of asteroids:'''
* Easy diggability (piles of loose regolith & gravel)
* Perfect shielding against space radiation even with just a few meters of rock (in contrast to O'Neill cylinders)
* Large open volumes with low risk of rupture even in the case of larger meteorite impacts (in contrast to O'Neill cylinders)
* Eventual minability all the way down to the the (weightless) core – at least for the smaller asteroids

'''Disadvantages and challenges of asteroids:'''
* Big communication lags due to speed of light => Big data-caches replicating Earth's internet
* Risk of "gravel gas" Kessler syndrome? Strategies against this issue?

'''Environment optimized for human well being / human psychology – the "zero gravity cavern park":'''
* what would be the optimal cavern size? <br>– probably pretty darn big to give an open air feeling <br>– but probably not as big as O'Neill cylinders making crossing the cavern with an [[microgravity locomotion suit]] unpleasantly slow and possibly even dangerous
* shape of the cavern – not too simple not too complex e.g. big bean shaped main body with some places tapering down into somewhat branching tunnels
* putting plants on the walls of the cavern
* putting ladders on the walls of the cavern
* lighting choices in the caverns – at times full brightness artificial sunlight
* emulated weather? – wind?, rain???
* "open air" restaurants as half open slowly rotating relatively small centrifuges in the walls of the much bigger cavern
* "open air" playgrounds, sports-grounds, art & educational galleries, ...
* entry points to the passenger transportation system
* Living quarters "underground" – also in small centrifuges big enough to not cause nausea
* centrifuge ponds??
* how would pets get around???

== Reasons for presence of larger human crowds ==

* space sports
* space tourism
* mining? perhaps unlikely given advancing automation by then likely needing minimal to no human presence
* having been born there
* ...

== Transport and Locomotion ==

* Underground passenger transportation – in the walls of the voids
* Floating lights (powered by rechargeable chemical energy batteries)
* [[Microcomponent redistribution system]]
----
* Effects of slow rotation of the asteroid on human locomotion in big voids
* Effects of minute gravity on human locomotion in big voids

== Resources ==

* Widely varying in the main asteroid belt – located at a good distance from the sun
* Silicate rich, carbon rich, metals rich, and even some water ice
* Resources not in the form of more easily processable gasses or liquids available <br>– well [[Ceres]] might have some liquid brine water underground

== Related ==
