Once inter-satellite links are operational, presumably. Looking at [1], there are already some polar orbit satellites, but without these links, that doesn't help Antarctica much. (I'm also not sure if the polar satellites are operational for regular traffic yet.) [1] https://satellitemap.space/

Can someone explain to me how you can have geostationary orbit around the poles?

You can't. For high latitudes you use highly-elliptical orbits, like tundra or Molniya.

There's also limited fuel that they have to conserve, so infinite snow does not mean infinite water.

Seems like a decent opportunity to use a nuclear reactor .. something like what you would find on a submarine.

It was tried! http://large.stanford.edu/courses/2014/ph241/reid2/

Precious space? Its a pretty big continent.

It's roughly a million times easier to grow food on the South Pole than it is to grow it on Mars.

We already tried that 60 years ago in Greenland, it didn’t end well.

And it's a million easier still to import it. So apart from hydroponics for treats and research, it's not a problem worth solving.

Whenever I read about how humans are about to colonize Mars, I think about how much logistics it takes to keep even a single base with a handful of people populated on the South Pole. It's like Mars, but with plentiful oxygen and atmospheric pressure, plentiful (albeit frozen) water, shielded from radiation, low-latency communication with civilization, and is reachable by air and ground vehicles. Given how difficult…

i think your observation is excellent.

but the entire Mars thing, the last several years, smells like Elon Musk trying to drum up interest to force government funding that he hopes to channel his way.

Another blog, about the french-italian base Concordia. https://www.gdargaud.net/Antarctica/WinterDC1.html

In years past there was also ABigDeadPlace.com, which has since lapsed due to the author's unfortunate death. Thankfully it was published as a book, _Big Dead Place: Inside the Strange and Menacing World of Antarctica_ by Nicholas Johnson. If brr.fyi strikes your fancy, I bet that book would as well.

We enforce rules in our society because they make that society better. Basic shared rules of behaviour are a precondition for social cohesion and prosperity, _not_ a luxury that we can only afford when everything else has been taken care of. This goes 10x in small groups in rigorous environments.

I wouldn't call resources in the Antarctic winter "incredibly scarce"; expeditions have been wintering South for decades now. We know what's required, and it's available, in quantity, with backups. It's true that people are trapped together for months at a time; we also rely on each other for survival. Under such circumstances, it's entirely backwards to claim "local society can't afford to have such strict standards." Just the opposite; strict standards of social behaviour are _required_ for the group cohesion and trust that's necessary for collaboration and survival.

A candidate who demonstrated this attitude would never get through BAS' hiring process. If, by some mischance, they did manage to make it South, they certainly wouldn't be overwintering.
