Like sports, the objective is ultimately useless except as a showcase of what humanity has to offer, and people like to see that.

If the goal was just to flex on the rest of the world I would've much rather we focused on going somewhere new or returning to the moon in a more sustainable way
Isn't this the point of this mission? If your point is "it shouldn't take this much money", then I agree. But also point to almost everything else.
After (and if) Artemis III lands on the moon and brings home the astronauts there seems to be very little planned on how we actually get to the moon base which NASA is claiming this will lead to, let alone the manned Mars mission that is also supposed to follow.
In other words, I think NASA is greatly exaggerating, and possibly lying, about the utility of this mission.
There is a lot of research going into in situ construction methods and even nuclear power plants on the moon [1]. (Which would be necessary to bootstrap eventual indigenous panel production [2].)
To me it’s encouraging to see this fundamental work being attacked than an endless sea of renderings. The reason you aren’t seeing heavy detailing, despite construction slated to begin with Artemis V, is we’re waiting for the launch vehicles. (“Any exploration program which "just happens" to include a new launch vehicle is, de facto, a launch vehicle program” [3].)

I smell politics and American exceptionalism, not science. There are a lot of could-bes in these statements as well, I have serious suspicions that these goals are not serious engineering. I am 99.999% certain that NASA will not build a nuclear reactor on the moon this decade, nor even the next decade. NASA is not giving me any signals they are capable of that.
You don’t think NASA and the DOE, together with Lockheed and Westinghouse, can build a reactor? Why? The major technical issues were largely de-risked with the 2022 solicitation.
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 can afford multiple SLS launches per year to maintain a continuous Lunar presence
Early launches, yes, because SLS is a garbage heap. Later ones, almost certainly not.
It's nice that we can send humans to space and it's good to keep that capability going so that the knowledge doesn't die. But the unmanned missions tend to pull the weight of actually accomplishing useful things. Humans just get in the way.
Space isn’t financed “exclusively” by taxes, either.
The Moon, I dunno, it’s at least in Earth’s gravity well so it isn’t like we’re going totally the wrong direction when we go there, right?
At best it could be a gas station on the trip to somewhere interesting like the Asteroid belt, though.
We are sending humans to (or around) the moon now, but it may just turn out to be a wasted effort, done solely for the opulence (or more cynically bragging rights / nationalist propaganda).
> We are sending humans to (or around) the moon now, but it may just turn out to be a wasted effort, done solely for the opulence
My 4 year old is extremely excited to watch the launch tonight because it’s manned. I’d say a few billion is worth it if all it does is inspire a new generation of astronauts, engineers, and scientists.
> inspire a new generation of astronauts, engineers, and scientists
This is a good point. And I would like it to be true. However when you have to lie about (or exaggerate) the scientific value of the mission, that is not exactly inspiring is it. Your 4 year old could be equally inspired by the amazing photos James Webb has given us, and unlike Artemis, James Webb is providing us with unique data which is inspiring all sorts of new science.
We have the capability to do that. We don’t have the will to do it, but we have the technology. We don’t even have autonomous robots that are capable of building a moon base on earth.
> Your 4 year old could be equally inspired by the amazing photos James Webb has given us, and unlike Artemis, James Webb is providing us with unique data which is inspiring all sorts of new science.
He’s not though. People gather around as a family and watch manned space missions. It’s exciting in a way that a telescope or a probe isn’t.
They have certainly contributed to my formation as a future engineer.
A manned mission on the other hand is tangible in a way a probe isn’t. “See the big round thing in the night sky? There are four people going around it in a spacecraft”.
It isn’t a _complete_ argument in favour of manned missions- that has to account for the risk of the endeavour and reward of the science potential of having people there to react in ways robots can’t. But it’s hard to pretend that the inspiration pretty much everyone feels when they see manned missions is somehow achievable purely by robotic ones.
Why do you say this? What is the bottleneck you feel we are more than half a decade from?
Without oxidizing air, it is easier to extract metals from the Moon rocks.
There is little doubt that it would be possible to build big spaceships on the Moon.
However, what is missing on the Moon is fuel. For interplanetary spacecraft, nuclear reactors would be preferable anyway, which could be assembled there from parts shipped from Earth, but for propulsion those still need a large amount of some working gas,to be heated and ejected.
It remains to be seen if there is any useful amount of water at the poles, but I doubt that there is enough for a long term exploitation.
If we want to go to Mars, the Moon is a good place to learn. Simple things like how to do trauma medicine in low g; how to accommodate a variety of human shapes, sizes and fitness levels; how to do in situ manufacturing; all the way to more-speculative science like how to gestate a mammal. These are easier to do on the Moon than Mars. And the data are more meaningful than simulating it in LEO. If we get ISRU going, doing it on the Moon should actually be cheaper.
If we don’t want to colonize space, the Moon is mostly a vanity mission. That said, the forcing function of developing semi-closed ecologies almost certainly has sustainability side effects on the ground.
What I really want is for us to send a lander and a launcher to Mars capable of returning to earth the the capsules Perseverance has been collecting. I would love for geologists on earth to examine Mars rock under a microscope. I would want them to take detailed pictures of an exoplanet using the Sun as a gravitational lens. And I would love it if they could send probes to Alpha Proxima using solar sails to get there within a couple of decades.
None of these would benefit from having a moon base. In fact this moon base seems to be diverting funds away from missions with more chance of success and more scientific value.
I do. Plenty of people do. Plenty of people also think exoplanet science is useless. I disagree with them. It the arguments are symmetric to those against human spaceflight.
> certainly not an engineering challenge
…how? We don’t have the technology to do this.
> There is no reason for humans to live anywhere other then on Earth. We have more reasons to live on Antarctica or the deep ocean then on the Moon, Mars or Alpha Centauri
Strongly disagree. You’re describing disrupting biospheres.
> None of these would benefit from having a moon base
Of course it does. ISRU (and baseload launch demand) decreases costs of access to deep space.
> diverting funds away from missions with more chance of success and more scientific value
The science slakes our curiosity. The engineering slakes our needs. And they both benefit from each other. Claiming Starship and in-orbit refueling won’t benefit scientific missions is myopic.
Surely you must see the difference between expolanet science and dreams of space colonization. The former is actual science which further our knowledge of the universe with tangible results, and the latter simply isn’t. People who don‘t like exoplanet science may have their reasons, but people who don‘t like space colonization are simply being realistic. Because the former is science, the latter is science fiction.
Finally there is nothing about space refueling technology which requires a moon base, and especially not manned moon missions. If you want space refueling infrastructure manned moon missions is not the only way to get there, and probably not even the best way. I also have my doubts here. If space refueling is so important we would be doing it already. Sending fuel from earth in a separate lunch. A case in point James Webb was originally designed with refueling in mind. They dropped it from the final module because it simply wasn’t worth it.
There’s some gravity: the wrong amount. In space, you can at least get 1G with centripetal force.
In orbit, you are halfway to anywhere. On Mars, you’ve gone back down the well. Make sure to bring enough gas to get out again…
Mars is just a bunch of irradiated rocks. Bring your own ecosystem, and wait a couple thousand years while it installs.
The only thing Mars has going for it is that it’s really far away, so we can still pretend to entertain sci-fi plans about colonizing it. The practical next step for space colonies would be large investments in additional space stations, a step so imminently possible that the only way to take it seriously would be to do it.
I’m not pitching a specific destination. And I’m not pitching exploration to the masses. Most people on the planet never have and never will leave their home country.
If we want to go to space, we probably want a lunar base.
> There’s some gravity: the wrong amount. In space, you can at least get 1G with centripetal force
Maybe this is important. Maybe it’s not. We need physiological experiments.
> In orbit, you are halfway to anywhere. On Mars, you’ve gone back down the well
In orbit you’re perpetually nowhere. On a surface you have in situ resources.
> Mars is just a bunch of irradiated rocks. Bring your own ecosystem, and wait a couple thousand years while it installs
Maybe it’s age. Maybe it’s moving from New York to Wyoming. Maybe those are the same thing. But I’m more of a red Mars advocate today than I was when I read Robinson’s trilogy in my twenties.
> only thing Mars has going for it is that it’s really far away, so we can still pretend to entertain sci-fi plans about colonizing it
It’s mass and an atmosphere. That’s a lot to what Earth has going for us.
> practical next step for space colonies would be large investments in additional space stations
Practical next steps are lots of experiments in centrifuges and micro and low gravity. To fund and focus that you need a goal.
> In orbit you’re perpetually nowhere. On a surface you have in situ resources.
It’s the bottom of a dried-out well in the middle of nowhere, that’s not an improvement over just being in the middle of nowhere with a full tank of gas.
>> practical next step for space colonies would be large investments in additional space stations
> Practical next steps are lots of experiments in centrifuges and micro and low gravity. To fund and focus that you need a goal.
The at least semi-plausible goal is the asteroid belt.
We should aim for the asteroid belt. Maybe we can mine them or something. It’d be less like a frontier and more like an offshore oil platform, but still, it is at least semi-plausible.
Fwiw do share your concerns about the methods (sending humans on this specific mission is questionable, SLS is questionable compared to SpaceX approach).
And in this mission in particular, you can't divorce science from politics. NASA's budget was reined in by Trump 45 and his admin picked Artemis because a manned mission to the moon invokes a particular feeling and memory, not because it benefits science. The moon is a known quantity, and going there is not more valuable than the other projects the government could have spent $100 billion on.
Keep in mind, this is one of the most expensive single launches in history while there is a partial government shutdown and the rest of the federal government that does real research has been gutted by this same administration. So it's tough to talk about "scientific value" when it's obvious that this mission is doing little science at the same time the government has decreed it won't be in the business of paying for science.
If you’re angry about this dumpster fire of an administration wasting money and gutting research (I am too), the answer is to fight for better funding across the board, not to tear down one of the few ambitious programs left that’s actually pushing the boundaries on what we can do. NASA’s budget amounts to a rounding error and isn’t zero sum with the rest of federal science funding, these are separate appropriations.
And as I said, agreed on the concerns about cost and sending humans.
Only if it helps you to call this "science", I would say.
> advancing our engineering capabilities in space is advancing the science
In this case, we are advancing our engineering capabilities to make humans survive in space, which is arguably completely useless.
Not only that, but we keep focusing on the easier and fun part for engineers. A real problem for surviving in space is life support, see e.g. this: https://mceglowski.substack.com/p/a-primer-on-long-duration-....
But it is a lot less fun than sending humans around the moon in a ship that doesn't need them at all, isn't it?
Even in sports you do not get "nothing", it has certainty helped advance the field of medicine.
We seem to have lost the technology of going to the moon we gained from Apollo. So without an actual follow-up and a tangible long term plan I suspect the exact same will happen this time around.
In contrast, we kept the technology of doing robotic missions in space, on the moon, and even on other planets and even asteroids (the latter two have much to improve upon though).
Some of it. Much for good reason. What are you referring to that we’ve lost that we would want?
