Mimas’s ocean appears to be relatively young, forming in the past 25m years when powerful tidal forces exerted by Saturn deformed Mimas’s core, warming it like a massaged squash ball. The heated core then melted overlying ice, creating an ocean inside the Saturnian moon.
we think of glacier water as pure, the water on Mimas is brand new and never been touched
I find it baffling that this guy gets sentenced to jail and pay 14 million dollars to a company that makes huge amount of profits, but at the same time when people die in the US because of unsafe work conditions the sentences are much less…
Astronomy: “a natural science that studies celestial objects and the phenomena that occur in the cosmos”
I suppose anything that happens in the universe is technically “a phenomenon that occurs in the cosmos” but this seems more suited to !nasa, which could definitely use the content. Would you consider posting it there as well?
I’m not the biggest fan of Lemmyworld, I prefer thematic instances such as Mander.xyz. Maybe we can consider this community as broader than strict astronomy?
I also prefer thematic instances, but try to find appropriate communities within those instances. Just because it’s coming from NASA, doesn’t make it astronomy.
Depending on which aspects of the project you think are important and want to discuss there are a few communities here that might be relevant.
Earth Science includes environment, and environmental impact seems to be the most popular talking point so far.
Noise and other forms of pollution are public health issues and there is a local community for that, although I’m not sure it’s really a great fit there.
Physics might be another choice due to the fact that a lot of physics is going into the engineering of something that reduces sonic booms.
Or maybe you just need to find the right thematic instance. For example, I’m registered on slrpnk for my climate, energy efficiency, and anarchism fixes.
Looks pretty damn cool, but supersonic commercial flights will be ridiculously expensive, pollutive and wasteful, there’s no going around this. There’s zero practical uses for the common man.
“Ok boys, we need ideas. We’re fucking the planet up irreparably in a way that will cost many, many millions of lives… but I feel like we could be doing it a lot faster. Get off your ass and invent a way for rich assholes to screw us even more than they already are”
It makes me so mad we don’t just tell the flight industry that by date X no planes that use traditional fuel can be produced, and by date Y that they won’t be allowed to fly. Doesn’t even need to a global agreement, if the European market is closed, than that could be motivation enough. And it would focus innovation on efficiency instead of frivolous stiff like this.
Intriguingly, the two structures are at the same distance from Earth, near the constellations of Boötes the Herdsman, raising the possibility that they are part of a connected cosmological system.
Not only that, but they look suspiciously concentric when plotted out on the sky. I know that's jumping pretty far out there into speculation land, but it'd really blow our theories a new one if there are patterns in the cosmos this large. Neat stuff.
