I have to admit, I've been an Artemis hater ($4 billion per launch lol) but the experience of watching people go back around the Moon has been incredibly inspiring, and it proves to me that maybe we can still do hard things
jameslk•1h ago
> $4 billion per launch lol

The US spends almost that much on net debt interest each day (~$3 billion/day[0]). Not that adding to the debt helps at all, but the old proverb about being penny wise and pound foolish seems relevant

0. https://www.cbo.gov/publication/61951

ToucanLoucan•1h ago
Also we spend that much every 4 days we're in Iran, and that's only ONE of our neo-colonialist irons in the fire, as it were.

If you want to make the US financially solvent, cut defense. Defense LAPS every other budget category. Whether you want to take the conservative position on why that is (our allies freeload on our defense spending) or the Progressive one (the U.S. is an empire in decline and every major empire through history has spent vast sums to maintain itself why would the U.S. be different) doesn't change the fact that our military budgets exceed over a dozen other nations' combined, the vast majority of whom are allies.

>Defense LAPS every other budget category.

I suppose it matters how you lump things, but for federal spending:

  - $678 B, Social Security
  - $478 B, Medicare
  - $425 B, Net Interest
  - $419 B, Health
  - $412 B, National Defense
  - $320 B, Income Security
  - $184 B, Veterans Benefits and Services
  - $75 B, Education, Training, Employment, and Social Services
  - $53 B, Transportation
  - $43 B, Administration of Justice
  - $15 B, Other

I think the common miscommunication here is that defense is the largest part of the US discretionary budget (about half overall), but that doesn't include those non-negotiable things like Social Security, Medicare, etc .

"Please note: Values displayed are outlays, which is money that is actually paid out by the government. Other sources, such as USAspending, may display spending as obligations, which is money that is promised to be paid, but may not yet be delivered."

The Biden administration's FY2025 defense budget request was $850 billion for the DoD, with the total national security budget reaching over $895 billion. The FY2026 proposal submitted by the Trump admin is 1.5 trillion for DoD.

The absolute cost isn't the problem, it's the value that we're getting from it. SLS and Artemis are both incredibly expensive and ramshackle programs, and regardless of how bad the rest of the USG might be in terms of their cost, or value, if you are a true space fan and a true American space fan, you should want this little corner of humanity to hold itself to a higher standard.

Acceptance of over costing and under delivering is exactly why the US is stuck with SpaceX as its prime space launch provider. It's only through the miracle of the vanity of billionaires that there's even a realistic second choice (Blue Origin) that might develop.

It's also this type of attitude that let's us be in a situation where we honestly don't know how well the heat shield will work on reentry (SLS launches are so expensive, and so slow to build and prep to launch, that we cannot fit in a uncrewed mission between 1 and 2 to test or validate fixes or models).

If Artemis as a program succeeds, it will be despite the incredible graft, pork, and ass covering, not because of it. I want Artemis to succeed because the achievement will be beautiful and amazing, and I want everyone to be safe and sound. I want Artemis to fail, to force a reckoning. I still believe that America has great things to offer to the world, but it's not going to be able to do that by muddling it's way through and cobbling together random pork filled programs into a vaguely inspiring shape.

$4B is chump change for the U.S.

Gavin Newsom alone wasted (laundered?) billions of dollars in California. The United States can send 10 rockets per day and wouldn't even feel the financial impacts of it. The states individually waste millions per day.

The longer term value of having moon outposts for observation, mining, etc. will pay off massively.

This is way bigger than just putting people on the moon or hubris. It's the prerequisite for everything we've also said about Mars. Elon just muddied the waters so much that people are so negative about anything else.

chrismcb•1h ago
Ignoring the fact that we aren't using money for rocket fuel (that is people are benefitting from us spending that money) the potential upside is immense. There are a time of resources available in the asteroids and a moon base makes mining those resources easier and cheaper.

Absolutely! What do you have in mind?

This is not a lot of money on a nation-state scale. It's equal to giving every person in the US about US$12.

I imagine it depends a lot on your outlook. Someone could see the system as the thing that made the experience possible in the first place, and feel a lot of gratitude and a sense of possibility as a result.

dylan604•20m ago
The external shots seem to just be from the GoPro strapped to a solar panel. Didn't seen anything that looked like the shots from the Nikons onboard. Was hoping for a couple, but I know I'm just being greedy wanting all the pics

edit: exif data shows some are from a Nikon. I just want to see them all!!! My greedy line still plays

aanet•15m ago
I was hoping that they used a medium format camera like Hasselblad or something for the larger pics... but no such luck. I guess weight might have been one factor.

Still, the pics are mind blowing. Out of this world, tbh

dylan604•10m ago
A 20.8 megapixel 5568 x 3712 pixels is not a shitty image. When we get to see those images, they will be much better than the GoPro images we're seeing

There needs to be a word for that feeling of dread you get when reminded of just how feeble and weak the average human mind is, and how tenuous of a grasp on reality most people have.
sho_hn•1h ago
Maybe I'm an eternal optimist, but sounds to me like they actually tried to put themselves into space, made the assumption that anything visible past the moon must be further out and were left with "wait, I thought it was supposed to be red?"

Uninformed, but not ignorant and perhaps even interested. I hope your response started with "No, actually, even cooler: ..." and you made a space fan that day.

dboreham•29m ago
I'd be genuinely curious to see a list of the things they had heard of, since Artemis has been in the news constantly for a month. E.g. have they just not heard of anything (consume no news), or are they in some news silo that excludes rockets, and if so what other things does it include? We may be missing something important that we've never heard of!

We're so not accustomed to moon pictures taken with "normal" cameras. These almost look like 3D renders to me, it's incredible
dylan604•12m ago
Why is normal in quotes? Do you mean visible light vs filtered monochrome with false-color outputs or infrared/radio/x-ray like some other telescopes use? Would that be the abnormal you are referring? The Apollo images were taken with Hasselblad film cameras that were "normal" cameras[0].

There is something uncanny about the bandwidth and quality of all the artifacts coming from this mission.

I've subsisted on photos from the Apollo missions and artistic renditions for so long that seeing the modern, high resolution real thing to be quite stirring in a way I didn't expect. It actually does make me believe that the future could be quite cool.

poszlem•19m ago
Yeah, I think we got so accustomed to that analog look that seeing them like this feels almost like viewing a World War I photo in full color and 4K.

I think my favorite of all these images is https://www.nasa.gov/image-detail/amf-art002e009287/. The sheer size difference, while simply a trick of perspective, makes Earth feel tiny and insignificant.

dylan604•23m ago
I listened to pretty much the whole fly by yesterday, and I was imagining how I would have spent my time at the windows with a camera. Listening to the comms made me think of that episode from From The Earth to the Moon where they take the astronauts out and give them geology lessons so they could be more productive with their descriptions.

I was also very curious of their descriptions during the eclipse where the Earth shine was lighting up the dark side of the moon to such a surreal look they couldn't really describe it. They were even commenting that they didn't feel the photos being taken were doing it justice either.

I also was wondering if they will make any modifications to the capsule since covering a window to block the Earth shine caused concern on the ground from some of the readings they were getting. Assuming it was overheating as they redirected air flow to the window. Then again, the following missions won't be so concerned with a single fly by so probably not something they'll address.

Zoomed into several of the lunar surface photos and noticed some of the very small impact craters are in a regularly spaced straight line.

Looks to me as if a meteorite came in at a shallow angle and basically skipped across the surface. Leaving dimpled craters as it bounced. Looks very similar to rocks skipping on a pond. Am I correct or is there another explanation for these?

A chain of meteors would strike the surface in a line as the moon moves
