Did you read it? They're prolific here and the essence of the post is a bunch of citations and quotes from Nasa's own staff and literature.

Yes, I've also read material outside of that article from NASA's own staff and literature. Statements like this: "Put more simply, NASA is going to fly Artemis II based on vibes, hoping that whatever happened to the heat shield on Artemis I won’t get bad enough to harm the crew on Artemis II." Are just so intellectually dishonest and completely ignore the extensive research and testing that's gone into qualifying thi…

So did they! And they showed their work. So far you're just beating around the bush.

What would would help is if you said something like "Maceij says modeling a different entry approach on computers is no substitute for a bona fide re-entry testing a new design, but that's incorrect because _____."

> Are SpaceX rockets a loser for society? That remains to be seen. By giving Musk the prominence to set up DOGE and destroy USAID, they've indirectly led to the deaths of almost a million people. By launching starlink, they're also increasing the amount of aluminum in the upper atmosphere, which may have catastrophic effects on the ozone layer.

Do government non-profit spacecraft not use aluminum? SpaceX rockets also are re-usable, which is environmentally better. They also cost about 10% of what non-profit rockets cost to launch. > they've indirectly led to the deaths of almost a million people. DOGE is a non-profit entity. Besides, why can't other non-profit governments pick up the aid?

To your last point, because DOGE shut down programs in a such a way as to make that impossible, to the point they chose to let food rot, let medicines go bad, and stranded Americans overseas working on the projects without a way home.

Each Artemis launch costs something like $4b (that's the incremental cost of a new rocket, it's much higher if you amortize the design costs). IMO the program is not optimized for cost or sustainability, it's optimized for creating jobs in various congressional districts. Of course that provides a certain amount of political sustainability to the so-called Senate Launch System. I just don't see a future where NASA ca…

> Each Artemis launch costs something like $4b Early launches, yes, because SLS is a garbage heap. Later ones, almost certainly not.

Regardless of whether this particular mission is perfectly planned, this is precisely the kind of thing that will help humanity outgrow the dark age of war, inequality and climate mismanagement. It is a noble endeavor - science, engineering and peaceful exploration hold the keys to our survival and prosperity. It is also important psychologically to our survival - a reminder there is a bigger pie, that we can solve h…

How do you figure? The previous Moon missions certainly didn't accomplish that.

Do you watch sports, football, the Olympics? If not I'm sure you know someone who does. Same category as this. Each of the 32 NFL team is worth about the cost of 1-2 Artemis launches. The entire league could fund the whole Artemis program nearly twice. Hosting the Olympics is worth about 3-10 launches. Like sports, the objective is ultimately useless except as a showcase of what humanity has to offer, and people like…

Even if you think Space travel is worth the money (which I personally do), adding humans to the mix makes projects incredibly more expensive. Even in the realm of space travel and research, sending humans is a questionable use of the money.

People are going to have to die in order for us to increase our space knowledge. It sucks but thats just how it be, it requires humans for most of it.

> Missions don't happen in isolation True. I wasn’t thinking about training the ground crews.

Only in the last few minutes, the livestream actually covered various goals this mission - explicitly a test mission - is meant to achieve. For example, one they just mentioned is they're going to be doing some docking maneuvers practice. This is not just training the current flight crew and ground crews, but is also generally testing the entire system - including operations and hardware too, with feedback important…

> testing the entire system - including operations and hardware too, with feedback important to logistics and component manufacturers, etc.

This can be done autonomously. The human training cannot.

I hope it does. But every day that goes by I feel that the future is just going to be like what's shown in the expanse series

You don't solve these problems in a single step, but notice how space imagery and analogies pop up every time people try to talk about peace, global problems, mutual empathy, understanding, etc. The Pale Blue Dot, images of Earth from orbit or the Moon, etc. Those are anchors in public consciousness, competing in memetic space with usual divisive, dystopian, hope-draining pictures and soundbites - we need more of them to improve on the big problems, and we absolutely would not have them if not for people actually flying to space.

Or, put differently, space exploration is one of the few things "feeding the right wolf" for humanity at large.

Sparked the environmental movement, to name but one major impact.
