Doesn't that post explain that this is just what they do, and that melting the snow is pretty involved?

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

With a 30 degree delta between temperature and wind chill, I'd think they're ripe for wind turbines.

If you're interested in the people and personalities and activities at the South Pole, the Werner Herzog film Encounters at the End of the World is a revealing and interesting documentary. It includes a fascinating part about a deluded penguin choosing to leave its flock and begin a fatal journey towards the center of the island... - https://en.wikipedia.org/wiki/Encounters_at_the_End_of_the_W... - https://www.imdb.c…

FYI, many people who spent time at McMurdo around the filming of Encounters are not big fans. The interviews were intentionally set up to make people look weird. The narration implies there's something wrong with "polar people." You might find us dissapointingly normal. A Year On Ice is a more accurate representation. I'm in Frozen Planet, but you can't believe all the narration in that either.

Just curious, what’s the male:female ratio of the typical winter crew?

On Mars you have soil you can process into something plants can use (note: needs to be washed free of its perchlorate contamination first) whereas at the South Pole there is no soil that is not buried under hundreds of meters of ice. You can't just create a heated greenhouse on top of the ice because it will melt the ice underneath. They've already done tests where they've grown plants in Martial soil simulant.

South pole. I'm not talking about Antarctica as a whole. There's plenty of areas on Antarctica's coast where small plants/lichen grow.

These stories about the logistics at Amundsen-Scott are a fascinating glimpse at the level of logistical complexity that'd be required for an off-planet (Moon, Mars...) base.

Every time I see people get excited about Martian human habitation, I note a lack of discussion of the essential intermediate step: a fully self-sustaining base in the most inhospitable parts of Earth.

Where are the Biosphere++ projects?

And Amundsen-Scott has it easy: pressure, oxygen levels, and dust aren't a problem! (granted: Martian equator has easier temperatures).

Also, I've long wondered what is the comparable level of yearly insolation (for sustainable power) in the South Pole compares to Mars' equator?

The shower page was interesting, you get 4 minutes of shower time a week https://brr.fyi/posts/showering-at-the-south-pole I'm surprised they can't just melt snow water to run things like showers. Oddly no suggestions on the page about doubling up your shower with someone else to have longer or more frequent showers.

There's only a few centimeters of snow per year at the pole, it's a high desert, and digging the ice out is probably not worth the energy?

The same blog has a post referring to snow accumulation (evidently wind-blown, not precipitated) requiring enormous operations and infrastructural efforts to keep the station from being buried [0].

There seems to be plenty of snow available, if you want to melt it. Energy is the issue.

Unfortunatly wind turbines are also not really a big fan of the cold. When ice grows on the blades they can become unstable.

2 people in a shower doesn't effectively decrease water usage per person, and the logistics overhead would eat into the 4 minutes.

If done with someone you find attractive, that also finds you attractive, 2 people to a shower, that want to participate in this shared activity of showering together, increases this thing called "fun". (Both parties wanting to participate is requisite for this "fun" to happen. If one or both parties does not want to, this "fun" does not happen. Even if both parties want to, that is not a guarantee that "fun" will happen.) Note that this "fun" is unable to spontaneously generate water, unfortunately. However, every rules lawyer will note that the limit is 4 minutes of water, and not a limit of spending 4 minutes in the shower. (8 minutes of water for two people.) Thus, two people may choose to spend additional time in the shower with the water off. If it is not clear to you what two consenting, attracted, naked, soapy adults could possibly do for "fun", please find and ask an adult that you know and trust.

The first people on mars will be self replicating robots. Due to the way the exponential function works - I think enough terraforming could be done really fast.

I wonder if there are libido-inhibiting drugs you can take, and whether that would help.

The British Army allegedly used Bromide in tea for this purpose in WW2 [0] [0] https://en.wikipedia.org/wiki/Bromide#Folk_and_passé_medicin...

Old joke from where I live

Two old vets (in their 90s) are sitting in a bench

The first says - Mate, do you remember the bromide they gave us in the military?

The second - yeah?

The first guy - Well it started to work.
