Artemis V

Artemis 4, targeted for 2028, is planned to be the first crewed lunar landing since Apollo.

Beginning with Artemis 5, scheduled for no earlier than late 2028, NASA intends yearly lunar landings to develop a permanent lunar base as a step forward toward human missions to Mars.

We can go a little bit into detail here.

The core infrastructure of Artemis consists of Space Launch System, Orion, and the Human Landing System.

The political coalition that funds this isn't permanent.

If Artemis IV slips to 2030, and Artemis V slips to 2032, the argument for canceling becomes much easier.

The answer

to Daniel's question about what preparations look like, in one line, is that the preparation is enormous, and it's happening on six parallel tracks, and none of them is fully done.
