Fair point, but that’s an argument about prioritization within NASA’s budget (and its size relative to other spending), not the scientific value of the mission.

There's never non-zero value to any challenging engineering problem. The question is whether the finite resources spent to solve it are best spent on it versus other projects.

And in this mission in particular, you can't divorce science from politics. NASA's budget was reined in by Trump 45 and his admin picked Artemis because a manned mission to the moon invokes a particular feeling and memory, not because it benefits science. The moon is a known quantity, and going there is not more valuable than the other projects the government could have spent $100 billion on.

Keep in mind, this is one of the most expensive single launches in history while there is a partial government shutdown and the rest of the federal government that does real research has been gutted by this same administration. So it's tough to talk about "scientific value" when it's obvious that this mission is doing little science at the same time the government has decreed it won't be in the business of paying for science.
