Im not really convinced SLS and Artemis are best effort projects; we improve through refinement, and the only way to get there is cadence. More launches with the same general mission requirements.

One launch a year is not even close to what we can manage with our current technology, to the point where the scope is too small to be legitimately worth doing.

Its not solely a matter of energy; its about opportunity for learning. The current scale is too small to be worth doing at all.

If it was a program of something like >50 payloads over a decade, that gives enough opportunity for refinement, in cost, safety, and scale manufacture methods to actually see something new.
