Two comments back to back on pollution.
New Shepherd runs off hydrogen and oxygen. Two parts hydrogen to one part oxygen.
There are valid reasons to call water vapor in the upper atmosphere pollution, but it's water vapor.
Actually it would be cool to calculate how many cars worth of greenhouse gases the trip produces.
Not sure how you get CO2 out of a hydrogen and oxygen mix, but ok. Calculate away.
The exhaust from New Shepherd is a combination of hydrogen and oxygen in a ratio of two hydrogen atoms to one oxygen atom. Sometimes called H20. Otherwise known as water.
Can they just stay there?
No.

How on earth did human beings survive without starving for the thousands of years between the start of farming and today?
We weren't "subsidizing Chinese manufacturers with free international shipping"
This means a fully trained NN can be recoded onto a single ASIC and run far faster on far less power.
Incredible. You've never designed a processor in your life but you've figured out something an entire industry of chip makers didn't.
I can only imagine what you'll fix next.
$2 billion per launch and Artemis needs many of them. It's not sustainable.
It's even worse than $2bln.

"In late 2021, a report by NASA's Office of Inspector General showed that NASA will likely spend a total of $93 billion on the Artemis program between 2012 and 2025, and that each SLS launch will cost about $4.1 billion."
there was nothing I couldn't do under Linux that I could under Windows, except maybe run SolidWorks or other CAD stuff, which was shoved into a VM and worked well enough. It would be nice if they supported Linux directly.
Fun fact: SolidWorks was created precisely because the founder was annoyed that all the good CAD software was for UNIX at the time and not Windows. Funded by his money from the MIT Blackjack team.
I'm not the OP you, asked, but I'm also a Debian 12 user. I started with Linux on desktop in 1998; bought a boxed copy of RedHat at a Windows 98 release party at a CompUSA.
And I don't have a reason to boot into Windows. First thing that happens when I get a new laptop is Debian goes on it. I don't really game, but Steam is nice for keeping some stuff on here I can play when traveling and feel like a game.
Admittedly I mostly code. With Microsoft tools. VSCode, deploy to Azure, cross-platform apps that run on Windows no problem, etc. It's a wild world!
On the other, I would prefer to see openAI remain, well, open.
Open as in... open to accepting credit cards? That's the only part of them that's open.
My guess is that SpaceX is tired of paying for all the roads and sewers and electrical infrastructure it needs to get its [not a] city to run. Why do that when there's all these [freeloading] residents there that can be taxed instead?
There were 26 freeloading residents in Boca Chica before SpaceX moved in.
Not much of a tax base.
Fair enough, but my point stands: rocket engines are re-started all the time.
You're still very mistaken. Restarting rocket engines is not common. You'd be hard pressed to find 12 models that could do it in all of rocket history. Currently flying in the US fleet would be the Merlin from SpaceX and the RL-10. Of all the engines on the Apollo stack only the service module's J-2 was a restartable one.
It's not an easy task to get fuel flowing into the engines when on orbit. It's hard enough on the ground where we've got all the room in the world for support equipment and we've got that constant acceleration from gravity thingy. When you start looking at what it takes to get things into a geosync orbit that restart ability becomes important, but even in those situations plenty are delivered where the upper stage cannot relight. They'll put propulsion on the final sat to do the final orbit raising rather than develop a restartable engine. China is still having difficulty in this area IIRC.
SuperHeavy can lose 3 engines at liftoff and still succeed.
The snap system actually does a nice job of this. Handy way to install closed source apps that just use a single image across everything.
They're kinda bloated, like a macOS app, but it works.
