Each Expendable Starship Super Heavy launched costs less than a single engine on the Artemis program.

Every time you see a Starship launch what you aren't seeing is manufacturing processes corrected, issues in launch protocols and field issues resolved. All the little things that build up to make your system reliable. Do you want the doctor who has done a hundred successful surgeries, or the one who has done one or two but spent a long time in school watching videos.

The big difference is in the end, Starship gets built faster, costs much less, and can do more. It's not even close.

You can't compare costs for a rocket that doesn't work yet. It's fictional. As I said in my post, if we are comparing fictional rockets then I have a $1 rocket that can fly to Jupiter.

Until it actually works every dollar is waste.
