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…

Starship "making LEO" is not a significant challenge--the existing flights have explicitly targeted a (very slightly) suborbital trajectory. They could have done otherwise at any point, but for now it's more important to guarantee that the stage comes down immediately. None of their current objectives require more than ~1/2 of an orbit. Starship v3 flying will be a significant leap, though. It's the first with the Ra…

> Starship "making LEO" is not a significant challenge

Of course it is. I say this as someone who sturdied astronautics.

You’re broadly correct, though. My point is the action shifts to Hawthorne and West Texas for the next year or so. Then pivots back to NASA for Artemis IV.

I wonder if Starlink works if the dish is above the satellites. Technically GPS can work from the moon.

Well, one side of it.

You don't solve these problems in a single step, but notice how space imagery and analogies pop up every time people try to talk about peace, global problems, mutual empathy, understanding, etc. The Pale Blue Dot, images of Earth from orbit or the Moon, etc. Those are anchors in public consciousness, competing in memetic space with usual divisive, dystopian, hope-draining pictures and soundbites - we need more of the…

It's crazy to believe that people who believe in one holy book are killing people over another holy book in countries like (but certainly not limited to) Nigeria, while another country launches people to the moon. But, alas, I agree with you. There's no way out but through I guess.

That other country has also people killing other people over a holy book.

And the next flight will use a different design. I wonder why?

Artemis II is scheduled for re-entry to Earth on April 10th. That is when the heat shield issue will be the most dangerous. If it fails and the mission fails with loss of life while knowing it went ahead despite the IG report about the heat shield... It might be the end of NASA. Hopefully it will return safely.

> It might be the end of NASA

If idiots and emotions rein, maybe. Then the centre of gravity for space exploration correctly shifts to Musk and China.

Come on man be honest. There were multiple, massive delays with the program related to literally every aspect. You're not engaging seriously.

The camera work was just terrible. They really need to learn from SpaceX how to do this right. Minus the obnoxious cheering. SpaceX does these beautiful drone shots and live telemetry so well. Considering that each SLS launch costs in the billions it would be nice to do a little better on production I felt the commentary during the launch also wasn't good. And I am not too interested in hearing from some Hollywood pe…

I love listening to the cheering because it really drives home what an accomplishment it is for the people who work on it.

Starlink launches don't get the cheering, so it's not like it's a laugh track.

Not just yet. Give it a few more years for AI (haha, another thing yielding stupid amount of value to everyone, that people are totally oblivious of - your antibiotics comparison in another subthread kinda applies too) - but for now, having actual people with full sensory capabilities, able to look at stuff on-site (and hear, and smell), is something we can't fully cover with computers and sensors.

Is this really helpful for a tech validation flight? We can put those sensors onboard.

> We can recover that and more data later, but it's a delayed, after-the-fact analysis. There's value in immediate feedback and immediate decisions

To a degree. We’ve validated vehicles remotely for LEO enough times that I’m sceptical we need humans for that. (Again, we do for ground-crew interaction training.)

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…
