This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
Reading an article on why Britain should settle Antarctica from Palladium got me thinking: are there any major, visionary projects happening at the moment that have a plausible chance of success?
I'm still hopeful for SpaceX to at least make operations on the moon more feasible, though I'm skeptical of making a real go at Mars colonization, especially as Elon's star has fallen so far recently.
China seems a likely contender, but I don't know what they have going on. I know that AGI is the thing on everyone's mind, but I'm thinking more about a physical, non-software based major visionary project that's happening in the physical world.
To quote some from the article:
This is culture war because, well, the decline of nations is extremely political, and from my view the Trumpian Right, for all it's many and varied flaws, is the only party at least nominally pursuing a future vision of greatness, instead of simply ignoring or managing a decline.
Also, this is a very sassy quote from the article I loved:
Starship isn't really made for the moon either. Their best bet is high-throughput LEO transport, but I don't think they'll get it to work for that either.
It's a bit off topic, but I doubt there'll be a better place to post it any time soon. I had a bet about Starship going to orbit with two other posters. It was driving me crazy because I couldn't find it for the life of me, and I was starting to think I got pulled into the Berenstien universe, but I finally managed to find the relevant comments, so I thought I'll post them as a reminder, and to make future reference easier:
Great timing on the tag, it looks like they made orbit tonight. https://x.com/SpaceX/status/1960179929204596907
Thanks for the bet, I have to admit I was sweating a bit by launch 10. Happy to discuss but as I understand it landing in a stable orbit was the main bet.
What? They weren't even attempting to reach orbit with this one.

Ahh ok clearly I am confused on what orbit means. So you want a stable orbit? Idk I don't think spaceships would ever try to get in a completely stable orbit since they're coming down, no?
ETA: Happy to pay the bet if I'm just wrong here, of course.
I mean, you even said "stable orbit" in the post above.
The "coming down" part is actually optional, and most of ships so far have been working without it, that's why reusability is such hype - you make them come back. Even Falcon 9 leaves it's upper stage up there.
OTOH, reaching orbit is mandatory. If you want to launch a satellite, you first have your ship reach the desired orbit, then you deploy the satellite. If you don't do it like that, they'll just come back crashing down. Only then do you start thinking about making the ship come back.
To be fair, I'm pretty sure they could reach orbit if the wanted to. Keeping the engines alight, after you get as far as they did, is the easy part. If my bet was with Elon Musk himself, he'd probably put one in orbit just to prove a point, but luckily for me they probably won't attempt it until they're reasonably sure they got everything right. Which means that you might be sweating for a while yet, and if you win, it might be a lot closer than you expected.
Yeah I may have been confused in making the bet, as @roystgnr mentioned above it seems they may never go “to orbit” and instead do suborbital velocities.
Starship was stable enough to release a dummy payload so I’m assuming that’s as far as they’ll go! Not trying to weasel out of the bet here just genuinely above my pay grade, hah.
Oh, no, they're definitely trying to go to orbit. Basically every use case they have requires it. Starlink satellites use low-acceleration argon ion thrusters to change their orbit after a launch, but they have to start from a low parking orbit that won't decay for weeks or months. (One time a series of solar storms reduced that to "days" and actually brought down a batch of satellites.) Starting from an orbit that reenters within 45 minutes is out of the question. Artemis missions and Mars missions have to refuel in Low Earth Orbit, and that again requires weeks or months of orbital stability, at a minimum, for the propellant depot Starship. These barely-suborbital flights are the best way to test everything, but even barely-suborbital is not suitable for an operational launch.
Their problem is that they're trying to get to orbit with a ridiculously huge payload (which is requiring redesign after redesign to make things more powerful and/or lighter) and then get back from orbit in good enough shape to reuse (which will require redesigns to make things more robust and thus potentially heavier), and so even when they have successful tests (the last version-1 flights, 4 through 6, were awesome) that doesn't guarantee that a major redesign will still be successful (the first version-2 flights, 7 through 9, were awful, and they had one v2 that didn't even make it to flight).
[Edit, to sum up the problem in one sentence: They can't safely go to orbit until they can safely go to orbit, and it's hard to both achieve and verify "safely" with a design that's still a rapidly moving target.]
My guess is that they'll go for a full orbit in the same flight that they attempt their first ship catch, which Musk claims will be 13 if everything goes right with 12 (the first v3 launch). They've got one last v2 launch for flight 11, and if they had a NASA milestone for orbit then I think they'd try to check that box then, but they don't (the next milestone is for ship-to-ship docking and propellant transfer, requiring two launches to orbit) so 11 will probably be another "fix stuff that broke or wore too badly on the previous flight and pick new spots to weaken to see what else they can push to the breaking point" suborbital like 10 was.
If everything goes right with flights 11 and 12 then 13 would probably be around December. I wouldn't bet on that, since even Elon is suggesting that they might end up waiting until 14 or 15 for a catch. And if the first v3 flights are as much of a regression as the first v2 flights were then the catch+orbit attempt would be flight 16 and wouldn't be until next summer. Even that would still win you your bet with months to spare, but the implications for the already-implausible Artemis 3 timeline would be awful.
What's your take on it's performance so far, in that regard? It seems to have taken quite a bit of time for it to pick up speed during launch, just with 16 tonnes of the dummy payload. It's hard to imagine it taking off with double that, let alone the 100 tonnes they're targeting.
