Need to let loose a primal scream without collecting footnotes first? Have a sneer percolating in your system but not enough time/energy to make a whole post about it? Go forth and be mid: Welcome to the Stubsack, your first port of call for learning fresh Awful you’ll near-instantly regret.
Any awful.systems sub may be subsneered in this subthread, techtakes or no.
If your sneer seems higher quality than you thought, feel free to cut’n’paste it into its own post — there’s no quota for posting and the bar really isn’t that high.
The post Xitter web has spawned soo many “esoteric” right wing freaks, but there’s no appropriate sneer-space for them. I’m talking redscare-ish, reality challenged “culture critics” who write about everything but understand nothing. I’m talking about reply-guys who make the same 6 tweets about the same 3 subjects. They’re inescapable at this point, yet I don’t see them mocked (as much as they should be)
Like, there was one dude a while back who insisted that women couldn’t be surgeons because they didn’t believe in the moon or in stars? I think each and every one of these guys is uniquely fucked up and if I can’t escape them, I would love to sneer at them.
(Credit and/or blame to David Gerard for starting this.)
at some point I read an article comparing the difficulty of settling antarctica with that of settling mars (mars is… much harder), and pointing out that settling antarctica would be so difficult that we have no reason to believe it will ever happen. found that pretty decisive
Implicitly assuming that the technology to terraform Mars is just around the corner is the we’ll become profitable once we hit AGI of space exploration.
Yeah, Antarctica is a cakewalk compared to Mars. The temperature is maybe in a comparable ballpark if you squint. Everything else is way easier. You can breathe the air as is instead of living in a pressure vessel with an artificial atmosphere 24/7. You have water everywhere you can simply melt or desalinate and you don’t have to even go to the even colder polar ice cap region for it because you’re already there. You have a magnetic field allowing for an ozone layer which is nice because the sun is a deadly lazer. There are organisms around you can eat for nutrition, and whatever resources you lack can be brought over with a boat or aeroplane instead of a spaceship. You can get to Antarctica from any human settlement (with the possible exception of space stations) or vice versa in a matter of hours. You can have near-instantaneous communication with other humans on earth at any time, whereas one-way trip between Earth and Mars will take a radio wave anywhere between 3 and 14 minutes, assuming there’s not some opaque body (such as a moon or a star) in the way. I’m probably missing a lot of other stuff but that’s the ones off the top of my head.
Sadly that isnt there on Antarctica, the ozone hole never was fixed, it just stopped growing. (And now due to somebody tossing aluminum sats in the atmos to burn up it will start growing again, which if there ever was a terraforming mars colony (there isnt going to be) would also not be great for any attempts there to fix the atmosphere).
from what i’ve looked up in five minutes (and knowing a bit of atmospheric chemistry) i’d guess the problem is chlorine and nitric oxide, not aluminum part. chlorine comes in as hydrogen chloride from ammonium perchlorate, and nitric oxide just appears when you heat up air enough, this means it also is generated during reentry and would also happen with oxygen/hydrogen rockets or any other for that matter. normally hydrogen chloride would be washed down, but when it’s high enough this doesn’t work. (there’s also soot idk about this one)
there’s alternative that does not introduce chlorine, and it’s even a bit higher performance, but it’s more expensive. (ammonium dinitramide) it’s also more of matter of interest for military, because it leaves less smoke
slightly related: in 2019 there was discovered an illegal CFC manufacture in China, by way of CFC emissions being higher than expected. i think it was spotted remotely and only later traced to China. by 2021 it was shut down, and it’s impressive because in CFCs, you’re working with very friendly things like carbon tetrachloride, hydrogen fluoride, chlorine, antimony trifluoride and not at rt, but like, 70 atm 450C, not exactly something you can run in a bucket, everything is corrosive or at least would destroy your liver. in order for this to make sense they had to set up entire factory with capable chemical engineers, and they had to know they’ll have customers that would violate Montreal protocol
Ah, I recalled it having recovered quite a bit some years ago, but apparently that was temporary and due to a weather event. Even so, the direly depleted form of Ozone layer present in the Antarctic is still better than anything Mars could support.
Not that solar UV is going to be your biggest problem when the atmosphere is so thin you might as well try to breathe in a vacuum and >90% of the little that is there is CO2. If you can figure out how to breathe, you can probably come up with sunblock, too.
Yeah the sunblock thing can prob be fixed, it just adds to a long list of ‘wow this whole shit sucks, and we didn’t even get dysentery’
