I'm writing up something around the economics of a deep space station (like ST Deep Space 9) and thinking that its viability depends on regular supplies, even though its role is as a supplier itself, with respect to being a refuelling / refresh post. So, much like a remote gas station there's got to be enough traffic (consumer demand) to make it economically viable to keep sending out tankers and paying staff.
Then (going a bit off-topic here) I started wondering how come we have several Antarctic bases, but no (well-known at least) Saharan desert bases, not to mention Arctic bases. Is it just that the Sahara and the Arctic are relatively more accessible, so you don't really need a 'base'? Or is it because the Antarctic is more economically-significant with respect to untapped natural resources - or is it scientifically more valuable (though sadly I'm struggling to believe this latter issue is the primary motive)?
So my question is whether Deep Space 9 is just a remote gas station or is its existence justified in being an extreme 'base' - i.e. a human/technological presence in a distant and inhospitable region of deep space. (Or is it just a fictional entity built near a fictional wormhole that is seldom used for any effective purpose in the TV series).
Thanks
