The goals it to fly often - adding a SLS launch to 2027 and a second launch to 2028. This drops the cost-per-launch, which is mostly fixed. It redoes SLS to make it less expensive and more capable. It moves the lunar space station down to the surface of the moon.
And it's budgeted at $10B/3 years, which fits into NASA's budget.
Isaacman took the Artemis program and fixed it. The reckoning came, and it's looking good.
There's a lot of potential in the announced changes and what SLS/Artemis might be able to become. This shouldn't prevent us from being critical of what SLS/Artemis most definitely has been for the previous 10-15 years.
And don't be fooled about the SLS launch cadence. As recently as summer 2025, Artemis III was still a nominally a 2027 manned lunar landing (https://www.nasa.gov/blogs/missions/2025/08/18/nasa-begins-p...). It got moved to a 2028 manned lunar landing in early 2026, before being converted back to a 2027 manned test flight.
The plan for SLS also does nothing to make it more capable (though hopefully less expensive). The cancelled exploration upper stage is being replaced by Centaur V, which is a less powerful stage. Isaacman refuses (I think rightfully) to really pin down on if there a future for SLS past Artemis V. If Isaacman chooses to cancel SLS after Artemis V (which I think is a defensible course of action), then SLS would represent a ~17 year long program that cost at least 41 billion dollars that netted 5 mission launches.
And characterizing it as "moving the lunar space station down to the surface of the moon" is... kinda falling into the trap. Lunar Gateway was supposed to launch ~2028 (along with Artemis IV - from the era where Artemis III was the first lunar landing). Gateway was a gongshow, and was delayed, and now cancelled. And now the new plan says the habs (the part that people think as an actual base...) happens in Phase 3 starting in 2033. The sort term elements they are trying to reuse from gateway into near term (think ~4 years) base projects are very "ancillary".
It remains unclear if NASA will infact be able to up the launch cadence of SLS to meet the double 2028 launch requirement. While it was clear that Gateway made... very limited sense for great expense, and the new plan is certainly ambitious with what I think is a stronger value proposition, it's also basically exactly as pie in the sky as gateway back in 2019.
The fact that I am doubting NASA's ability to execute now, is the very cost of SLS (and friends).

SLS will never be worth it. But I'd discount from that price tag the continuity benefits of keeping the Shuttle folks around, and aerospace engineers employed, across the chasm years of the 2010s.
Yeah, it’d be really nice if we could somehow express the strategic capabilities maintained in these discussions. Because on the face of it, SLS looks terrible, but paying that much to maintain the national capability to make something like the shuttle and SRBs feels reasonable.
Kind of similar to farm subsidies and the strategic implications there.
> paying that much to maintain the national capability to make something like the shuttle and SRBs feels reasonable
It’s reasonable to pay something. I’m unconvinced $41bn is the correct amount.
> Kind of similar to farm subsidies and the strategic implications there
There aren’t many. Countries in which farmers aren’t swing voters don’t have farm subsidies. I’ve been looking into buying some farmland and just collecting CRP on it, for example.
The new NASA administrator, Isaacman, seems to have done a very good job of convincing the various Senators to, if not get rid of the pork, allow him to allocate it in a way that benefits the lunar program.
The result was the Ignition event, which looks like it's planning to send up 17 small and 4 crew-capable landers by 2028, along with a fleet of orbital assets.
You can find out more https://www.nasa.gov/ignition/ , especially the "Building the Moon Base" section. The cost is $10B spread out over 3 years.
Artemis II is not safe, at least by the standards we apply to things. It's the third flight of a capsule, on the second flight of the rocket, and the first flight of things like the life support system.
At the end of the day, one of the reasons astronauts are respected is they understand those risks, and go into space anyway. That doesn't mean we shouldn't try to minimize risks - but at some point the risk becomes acceptable, and the cost of reducing it too great.
To paraphrase a quote from Star Trek - risk is their business.
Interest also compensates for the other things that money could be doing. If I didn't loan it to you (or a student), then I would be doing something else with the money, even if just buying a government bond.
I'm not sure that is accurate. You need a borrower to do that. If there were other low risk borrowers they would also lend them money, it's not a zero sum game. I'm no banker, but pretty sure the bank doesn't lend itself fractionally reserved loans and buy t-bonds.
College grads also pay on average 10x the taxes above a HS grad, so there is a huge disconnect on the repayment the lenders get. Once you pay the SL amount in taxes, you should be done.
New NASA administrator Isaacman has redone the Artemis program. The changes were announced at the Ignition event a few weeks ago:
