I'm not being a hater, but we landed on the moon 55+ years ago and now we're doing a flyby with 35+ year-old engine tech. It's good that we're doing something but we should be doing better.

You’re not seeing better engines because there aren’t any. We are reaching the limits of physics. That’s why we are working on alternatives like refueling in space or reusable ships. The Artemis missions are testing things that we still have a lot of area to improve upon — materials (a huge one), international standards for things like docking ports, computing, radiation safety, and a lot more.

Yeah, RS25/SSME still have a higher specific impulse than any boost stage engine in operation, past or present.

I don't think OP's problem with it is that it's "political" but that it's a product of pork and corporate welfare. The political thrust of the Apollo program was more "beat the Russians" and less "funnel money into dozens of already-rich corporations in favored districts." Even thought there was a lot of that, too. Modern space (and defense) projects seem to be almost 100% "pork funnel" and zero anything else.

It's not "almost 100% pork funneling" and I know this because....they're there! they are at the moon! I don't like pork either, but let's not blow this out of proportion. How much do we think that it should have cost, if everything was perfectly optimized, to get to the moon? 50b instead of 100b? so ok, 50% was pork, and that's bad, but let's not overstate it and instead allow a little joy in our lives. also the orig…

Only 300b for the Apollo program? That sounds downright lean.

I like how most people's reactions at this point are "yeah, whatever", as if it's every day that humans observe the far side of the moon with a naked eye through a window :). We do know what it looks like and we have photos from the surface, yes, but seeing the reaction from real people who're actually there does hit different, at least for me

It's also not the first time humans are seeing the far side of the moon, Ronald Evans orbitted the Moon 75 times in the orbital module during Apollo 17 (and other ppl did before him), so he also saw it right? The only unique thing is that its the first mission where they dont really do anything more interesting than looking at the far side

Apollo 8 did pretty much the same thing so not a first there either, but a first for today’s Orion architecture.

Also the heatshield is designed in a way that is cheaper to manufacture but less safe.

the hell does that have to do with anything

the comment i'm replying to is saying that the moon mission is morally dubious because we haven't solved domestic poverty

that's absolutely not what he said lmao. he said it's far down on our list of priorities, which is true.

It’s approximately the dark side when the moon is full, which happened two days ago.

> It’s approximately the dark side when the moon is full, which happened two days ago. Who downvotes that? It is true. Edit: maybe you can illuminate why you downvote?

I'm sure it's the flat-mooners downvoting.

> We can either hold ourselves back an an endless and futile journey on solving the human condition of poverty and inequality, or we can explore the stars. It's an easy choice. Wait... Are you suggesting that "exploring the stars" is less of an endless and futile journey than dealing with poverty and inequality?

Solving poverty and inequality is for the short term - they'll come back and need solving again no matter how many times you already solved them. But once the stars are explored, they stay explored forever. So yea, that's moving forwards and the other isn't.

The closest stars are way too far to reach on any reasonable timescale. That's not even mentioning the fact that moving forwards is a vague goal. Moving forwards towards what exactly? And if the US government got off of it's ass to... Oh I don't know, maybe fix the bullshit healthcare system we have and help people with tax money instead of bombing people for Israel things would improve quite a bit in a very short time. That's assuming we don't bomb each other over terroritorial squabbles first. In any case I don't really understand your defeatism when it comes to inequality but when it's something as difficult as interstellar space travel you seem to be optimistic.

There is literally not many things in life I hope so much for than starship success. Sounds strange perhaps but I just love space and I hope it succeeds. Funnily I absolutely despise Musk at the same time for being absolute buffoon

We're days away from the SpaceX IPO that will make Musk even richer than he is now. I don't trust him with that money.

Last time he got a bunch of money he used it to fund SpaceX and Tesla.

Now also Neuralink.

It’s hard to imagine anyone else who’s done more for the planet with his money than Musk.

Am I losing it? They can’t be seeing the far side of the moon right now, because they haven’t adjusted course to go round the far side of the moon yet… So does this suggest the BBC is wrong and it’s the side of the moon we’re used to seeing, but just it’s “dark”? But then the astronauts are saying it’s weird seeing the moon in a whole new light (excuse the paraphrasing pun). I don’t understand.

I was also very confused, but after some reading I figured it out. > In an interview with NBC News from space, NASA astronaut Christina Koch described seeing the moon out the window of the Orion capsule and realizing that it looked different from what she was accustomed to on Earth. > “The darker parts just aren’t quite in the right place,” she said. “And something about you senses that is not the moon that I’m used…

> “And something about you senses that is not the moon that I’m used to seeing.”

Almost philosophical /S

We are doing multiple productive things. Zillions of them. They are like 50 companies making robots right now that will soon do a lot of work. There are advances in many fields. Headlines are dominated by something else, the 'news' is not a good reflection of reality.

What about the workers that will be eventually replaced by said robots? You think they're just going to get free money to exist? Most likely they'll end up in the private prison system or in institutions while the corporations pocket all of the savings. Things are a lot more complicated than they seem I think...

95% of us used to labour as serfs on farms. 4.5% were technical trades. 0.5% noble class, 0.01% high elite.

The industrial revolution moved almost 95% of people away from direct agrarian labour.

We'll find ways.

It won't be pretty in some cases, but we'll figure it out.
