watched this with teary eyes. it truly shows what we can do when we come together and challenge ourselves for the greater good of humanity.

Same. I watched Apollo 11 launch in 1969 when I was four. Watched on our neighbor's TV. We didn't have one. Imagine what we could accomplish if we didn't suck.

sending people to the moon was never useful. We can get more done with robots, both cheaper and safer. There are plenty of more useful things we can do instead.

okay what is more useful is a matter of opinion. you can disagree, but I stand by it

Earlier quoted context omitted.

Global rates of poverty are 83% lower than they were in 1969 when we landed on the moon. So actually, millions of lives have massively benefited from science and technology. To be cynical in the face of all that is a personal take, not a reflection of the facts.

Obvious post hoc fallacy

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.

Let's not jinx them; let them get home safe before we take a victory lap.

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.

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

Because the goal of the program is to return humans to the moon. Artemis I was the unmanned test. This is the first manned test, and what they learn will support the subsequent missions that eventually land humans on the moon.

This is the same way that all manned spaceflight programs are conducted. You iterate and learn a little bit at a time. "Move fast and break things" doesn't work here. :)

I don't know why you're getting downvoted. The camera work was atrocious.

It's not just frilly video, it's how the world sees it, emotionally connects to it, and grows up loving it, and wanting to support more.

We had black screens as it left the pad, they didn't know what camera to switch to and kept changing feeds every 2-3 seconds, they switched to a grainy feed of the crowd just looking up while booster separation happened, so we missed that, and hastily switched back after they separated.

All the prep and they couldn't come up with a media plan? Maybe it was technical problems and their camera indexing was off or something.

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…

I hope so, but if this goes awry in any way, especially if – god forbid – they lose the crew, my fear is it’ll be a blow to the American hegemony that will be very hard to recover from. Orange man is bad, but I think something like that would add a whole other dimension to the US’s loss of face. I’m as anti-american as they come, but despite everything Pax Americana must be acknowledged and I shudder at the thought o…

> Pax Americana must be acknowledged and I shudder at the thought of it shattering.

Shudder away! We've already had both Carney and the finance minister of Singapore essentially declare Pax Americana to have ended. Everybody else is just being polite.

[EDIT: prime minister of Singapore, not finance minister]

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.

Minutes after launch they reached "ten thousand miles per hour". That's 2.78 miles per second. Nuts. No doubt the speeds go even higher later too.

I'm sure people here are already familiar with the speeds these things go, but that's the first time I've confronted a fact like that and it blew me away.
