The failure of the upper stage is a bummer. If it triggers a months-long review, that will almost certainly bump back the schedule for the prototype Blue Moon lander launch.

I know insurance for a launch is typical, but seems really tough to do that for this still “rather experimental” launch. I got to imagine it has costs something like 50% on a project like this.

Once Elon showed how to do it, and how cost-efficient it was, a rocket company that doesn't do it is not viable.

Spacex first landed an orbital booster just over 10 years ago and have now landed 600 times.

The entire rest of the world combined has done it twice.

For a long time people would scoff when it was said they had a 10 year lead, and that others would catch up quickly. Proof meets pudding.
