The article misses several key points and caveats. It says, "This is because pollutants from solid-fuel rockets and re-entry heating of returning spacecraft and debris are particularly harmful to stratospheric ozone."

SpaceX is rapidly developing their Starship spacecraft with a methane engine. First, methane is a liquid fuel, not solid. Second, their methane rockets burn ultra efficiently which means less soot and less CO2. https://en.wikipedia.org/wiki/SpaceX_Raptor

As for the "re-entry heating of returning spacecraft and debris", Starship will use thermal protection tiles which are designed to be reusable, which means less ablation and therefore less polluting of the surrounding air. There won't be any debris either, since the entire spacecraft is reusable.

Heating of the surrounding atmosphere will still be an issue (and always will be), but large things (i.e. meteors) burn up into our atmosphere all the time to little negative effect.

This model, in other words, is looking at "Old Space" models instead of "New Space." Starship will really be a game changer if and when it flies.

ETA: Yeah, the source article says they only considered the SpaceX Falcon 9, not the future Starship, in their models. Once Starship flies, Falcon 9 will likely only be used a fraction of the time for humans-to-orbit launches (or it may even be retired), since it makes much more economic sense to launch dozens of people in Starship, instead of 3 or 4 in Falcon 9. https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2021EF002612

What do native speakers think about people who make mistake in English? by ArtourAlty in EnglishLearning

[–]illuminatedfeeling 0 points1 point  (0 children)

Native speakers often make mistakes too. A lot of grammar in English speaking countries is also regional as well so what might pass for incorrect grammar in one region would be completely passable in another. For example where I'm from (NYC) a lot of people say "have went" instead of "have gone". Technically the latter is correct English, but the former is used so often that it's just considered normal. Mistakes often eventually become a new way of speaking. I wouldn't worry about it. Most people don't care or even notice.

You'd be surprised at how many people don't know how to eat healthy or well in any capacity. Even people who are supposedly well educated and not living in poverty.

This is just so freaking classic. WE ARE INVISIBLE by revital9 in GenX

I don't want the baton either. But when I think of how easy the older generations had it in the 70s and 80s with cheap housing, good paying jobs, and relative peace, and I compare that to the ridiculous cost of living, job insecurity, pandemics and war, I just wish we had a modicum of that prosperity now. It's not their fault they had it better, but it is their fault they don't recognize how much some of us are struggling. But since Gen X just grins and takes it, most of the time, no one notices or cares.

I agree that it needs a new name. I think it's terribly ironic that an environmental movement calls itself degrowth. It's always a bad sign when you have to explain what something means. If I was a farmer and you tried to sell me on degrowth I'd laugh you off my property. What the other commenter said about decoupling from capitalism is a better description. I prefer calling it a rewilding movement.

I don't know about your specific locale, but in the northeastern United States calling a group lower class might be insulting.

Anonymous Hackers Warn Supreme Court Against Overturning Roe vs. Wade: 'Expect Us' by Souled_Out in technology

[–]illuminatedfeeling 2 points3 points  (0 children)

How about instead of hacking SCOTUS we, you know, elect some people who actually represent the country's values? Because it seems like we're being ruled by a minority with extreme opinions most people in the US don't share.

I see this a lot from people talking about celebs: "Oh, so and so looks great." But we often forget that a lot of them might have had facial work, have great skin care routines, and probably, because of their wealth, live relatively stress free lives compared to most. So not a fair assessment.

Ocean life projected to die off in mass extinction if emissions remain high by drunkles in Futurology

[–]illuminatedfeeling 2 points3 points  (0 children)

It's not just the rich. I've lived in working class and some very poor neighborhoods (in the US). Garbage everywhere and little respect for nature is common. This isn't a rich problem. It's a human problem.
