It is very disconcerting to see so many completely disregarding incredible technological innovation because other problems exist, especially on HN. If we were not allowed to progress technology until everybody is 100% free of suffering, we'd never be able to create technological that may potentially lead to the alleviation of suffering. It all feels very crabs in a bucket - "I don't feel happy so nobody else should,…

There is no technological innovation in the Artemis stack. Three of the main engines are refurbished Shuttle engines. The fourth is a clone that cost more than the entire SpaceX Starship stack. The boosters are derived from the Shuttle SRBs. It's a late-60s technology rocket stack with a 2000s-era flight computer. It's such a travesty.

I believe the fourth is actually built from left over STS engine parts and they haven’t gotten to the clones yet.

I do hope the doomers who think that the entire US government has been completely gutted will take note of this. The government workforce is in a bad spot for sure, SLS is far from a perfect program, but this still demonstrates that we are doing some real work still.

It’s Orion that’s dodgy as fuck not the booster. I.e the new thing. Not the decades old, proven, launch engines. Let’s wait for the back patting when they splash down. I genuinely hope not but i am worried about this craft.

>Not the decades old, proven, launch engines.

Which are, I will note, being expended on this single launch, despite being designed, built, and functioning over decades as re-usable engines.

This is a new space race. From a geopolitical level, a nation that has a better presence on the moon will have a better strategic advantage.

What about the mineshaft gap though?

What about it makes you think it is important?

I get that not everyone, even on HN, thinks crewed-spaceflight is worth doing. And I certainly get that launching people to the moon doesn't makes up for the latest crap thing Trump is doing to the world.

But I really think that space exploration could be the thing that unites everyone, and the more unified we are--the more we feel like we have a common purpose--the easier it will be to solve our other problems.

I for one pledge to support space exploration (crewed or uncrewed) regardless of who is running the government. I will cheer Artemis II even though I voted against Trump. I will cheer if/when China sends people to the moon. I will even cheer if Russia does something cool in space.

> is no technological innovation in the Artemis stack Scaling is still engineering. And the environmental control system, laser-optical communication systems and block-construction heat shields are new. For Artemis III, in-obit propellant transfer will be new and transformational.

The block construction heat shield was new on Artemis I. Now we just know that it is an unfixed problem that will be done differently on future missions.

And Artemis III has nothing to do with in-orbit propellant transfer, that will be SpaceX and Blue Origin testing independently of Artemis III.

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…

The engineering was done in the 70's and 80's. This rocket is built out of leftover shuttle hardware.

The exploration in this mission was done 50 years ago.

I fail to see how this mission is noble. It's biggest accomplishment is keeping the NASA beurocratic apparatus in tact.

This spectacle of a mission is precisely the kind of distraction which enables complacency and allows the "dark age of war" to remain dark.

Is the problem inequality or rather poverty ? Because those are not the same thing. What we've done in space has absolutely helped with poverty. It makes weather forecasts possible, which helps even the poorest farmers. This can happen at the same time a handful of people become obscenely wealthy from it. Though in Musk's case, I suspect the wealth is a bubble which will pop before he can cash out more than 8% of it.

This is a policy decision insofar as the policy isn’t to liquidate entire groups of people over class and status resentment. “Just redistribute the wealth bro, it’ll work this time bro I swear let’s just do a redistribution”.

Until nukes are going off, Pax Americana stands strong.

That's just deterrence. Pax America (used to) mean something much more than that.

When the US stops being the main topic on the internet then you'll know it's over. As it stands everyone is still fully obsessed with America. Their cultural dominance is far from over.
