There is no technological innovation in the Artemis stack. Three of the main engines are refurbished Shuttle engines. The fourth is a clone that cost more than the entire SpaceX Starship stack. The boosters are derived from the Shuttle SRBs. It's a late-60s technology rocket stack with a 2000s-era flight computer. It's such a travesty.

> is no technological innovation in the Artemis stack

Scaling is still engineering.

And the environmental control system, laser-optical communication systems and block-construction heat shields are new. For Artemis III, in-obit propellant transfer will be new and transformational.

As someone who watched the Apollo 11 launch live on TV, this is no less awe-inspiring. This transcends nations, languages, and politics. This is of and by all humanity.

(If anyone managed to get the perfect shot of the spark-filled separation feed, please share. That was... incredible.)

It's not about the Orion unit specifically but the fact that this is happening in the first place. This is simply a precursor to future missions and the construction of the Artemis Base Camp.

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.

Think of all that cheese.

But we already learned there is no cheese there, that’s why we never went back.

It's much more popular to be doomer and a critic on the internet. Virtue signalling etc.

> It's much more popular to be doomer and a critic on the internet

Is it more popular? Or is it just easy? Dismissive “reads” are done by the picosecond; there is just much more to choose from than constructive thinking, which takes work.

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

We didn't have robots in 1969, and the Apollo missions resulted in many of the technologies that make modern robotics (and robotic space missions) possible.

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 think these space projects are great, can create much good will, and give people dangerous things to do that are worth risking the danger for. But war, inequality, and climate mismanagement are political problems that are not going to be solved (if they need to be solved) by science and engineering (the first two at least).

April 6: flyby April 10: splashdown After that, the exciting work will be in Starship making LEO and testing propellant transfer (a humanity first) [1] and Blue Origin testing its rocket and lunar lander [2], both scheduled for 2026, to enable Artemis II (EDIT: III), currently scheduled—optimistically, in my opinion—for next year. [1] https://en.wikipedia.org/wiki/List_of_Starship_launches#Futu... [2] https://en.wiki…

This mission is Artemis II. Is Artemis III the one with a lander?

> Is Artemis III the one with a lander?

Not anymore. Artemis III is now a LEO systems check [1]. Comparable to Apollo 9.

(Side note: when did we switch from Arabic to Roman numerals?)
