I tuned in for 60 seconds, the presenter got everything wrong, and I just tuned out until liftoff. She called the top of the ET (well, it's no longer an ET, but it's the stage that was the STS ET) the "upper stage". She said that the propellents are stored at thousands of degrees below zero. And so on. This is a NASA presenter?

And so on. This is a NASA presenter? To be fair to her, she seemed to explicitly refer to what sits on top of the core stage, it just wasn't in the diagram she was gesturing to the top of at the time. To be fair to you, I th…

Jesus! Why is there a presenter? Why isn't it just a livestream of the mission control radio chatter? That sort of shit belongs on some 24/7 news broadcast.

It's been 54 years since humans last visited the Moon. Hopefully, in a few years we will get boots back on the surface.

Out of curiosity, why do you see this as a worthwhile endeavor? My personal perspective is that the resources are better used for other purposes, but it's possible that I just haven't encountered some compelling reason yet.

You're right. The future of humanity is not in space, but in venture-backed smartphone apps.

Whether a moon base is needed or even beneficial is a question I have not heard a convincing answer in favor. And even if moon base is indeed needed and/or beneficial to future space exploration / resource extraction why robots cannot more efficiently build (or assemble) such a moon base is another question I need an answer to. We are sending humans to (or around) the moon now, but it may just turn out to be a wasted…

We are nowhere near the capability to launch robots to the moon that can autonomously build or assemble a moon base for any useful definition of moon base. > 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 i…

And neither are we anywhere near the capability to lunch construction workers to the moon which can build or assemble an equivalent moon base with their human labor. So this answer does not satisfy me one bit.

> 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 lived ~60 miles North of the Cape when I was a young boy, and watching the Saturn V's go on the way to the moon was a forming experience.

I lived in Port Orange FL until i was 12, during night launches my dad would take the family to New Smyrna Beach or some where a short drive South where we watched the shuttles come up over the water somehow. I can't remember the details it was a lonnnng time ago haha. I do remember the launches sounding like popcorn popping. I live in Dallas now and will be turning 50 soon, i want to catch the next Starship launch l…

You probably watched from the Florida side of the intercoastal waterway between the main part of Florida and Cape Canaveral. Because of the 3-mile minimum and Patrick AFB it is pretty hard to find a good watching place that is actually on the cape.

> in the same way that you'll probably survive one round of Russian roulette Is that with or without spinning the chamber between rounds? The odds are worse if you spin each time. They get worse as the game goes on if you don't spin.

> The odds are worse if you spin each time. How do they get worse if you spin? It’s still 1/6 odds of dying,iid events.

It's 6/11 overall chance of dying if spinning, no?

From a quick search, this page explains it: https://mathworld.wolfram.com/RussianRoulette.html

I think there is a major difference though. Sports events are not pretending to be anything else. The Artemis mission claims to be advancing science and claims to be a stepping stone for an eventual moon base and a manned mission to Mars. I personally have serious questions about all of these.

The fact that we hope to get some new tech with this whereas sports aims for nothing is just icing on the cake. I think big space missions are worth it every now and then on a humanitarian level; even if no new discoveries are made, a new generation of engineers will become fluent in what we have already discovered. Humanity's education is not "done" when the last fact is written in a book, it needs to be constantly…

> a new generation of engineers will become fluent in what we have already discovered.

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.

It is a bit chilling to watch these astronaut profiles having just read yesterday about the heat shield issues observed on the prior mission, and that this will be the first time we can test the heat shield in the actual pressures and temperatures that it will have to endure. Godspeed crew of Artemis II.

I had to watch "go at throttle up" on replay on the news in 1986 for the entire year, like almost every newscast

I was only a teenager and it burned into my brain badly

To this day cannot watch any launch with people onboard live

Truly. I'm not sure why anyone needs to be on the rocket at all, let alone our best and brightest.

Yeah. Doesn't really make sense. The entire mission could be done remotely.

Even with a goal of eventually putting humans on the moon, it'd be better to do an automated run, measure everything in the cockpit, and put in sandbags and/or something to consume O2 to make sure the CO2 scrubbers are working correctly. It's maybe cruel, but a few dogs would work fine for that sort of thing. A flame would be better, but it's pretty dangerous.

The first mission in decades doesn't need to have humans in it.
