Nasa unveils quiet supersonic aircraft in effort to revive commercial flights

And exactly how much CO2 emissions does this thing generate?

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.

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.

Would be nice to see this much time effort and money put into electric planes

I hope this is relevant for this community, let me know otherwise

I think it’s close enough and I’m happy to see it.

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.

I just noticed there is !space, it could probably fit there. The issues is that it is 10 times smaller than !astronomy.

Anyway, next time I’ll post something definitely related to space to avoid the doubt

“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”

1.4 times the speed of sound – or 925mph (1,488 km/h)

I feel like I’m going mad
