It's almost showtime for SpaceX's Starship rocket

Maybe it was prescheduled, but it seems kind of weird. Tbh I'm jealous of those kids.
1. As with the first flight, the absolute minimum target is probably clearing the tower, and this time without causing any significant damage below, suffering booster damage, and if another anomaly happens to have the AFTS function flawlessly. That wouldn't make them super happy but would be a real improvement and also avoid serious government review again, so they could do the third faster (remember it took quite a few hops to even progress this far).
2. MVP is for Starship to get to target orbit (or at least show it could have even with a ballistic test trajectory) and SH to be recovered. If they can get that far, then they could start using it for Starlink launches and have it start doing real work and generating real value as part of testing even if SS ends up "expended" for awhile as they figure out reentry.
3. Obviously final goal is full reuse. But then also having fast and cheap turn around, optimization, lots of reliability, they'll no doubt be iterating for a long while as with Falcon 9. Even full launch and recovery in some ways only marks the end of the beginning of Starship's life.
4. And then they'll need to figure out in-orbit refueling, and different models of Starships.
5. And then eventually deep space to Mars? Major private customers and partners for Starship's capabilities doing things SpaceX doesn't want to and providing further cadence and funding? If that does indeed end up being Starship vs using Starship as a stepping stone to something more. It's hard to really predict the kind of cascading effects of such a shift in economics. It'll have both business and political implications as people spot new classes of opportunities.
All really exciting to even be able to contemplate in such a concrete manner though. Probably other stuff I'm forgetting or am ignorant of, but it'll be a long and very cool process to watch unfold. As a Starlink deployer I'm also most directly excited to see what will happen when they can begin launching full size v2 en masse, and perhaps start experiments like making Starlink also accessible to satellites, space craft, moon communications and so on too vs purely terrestrial.
And successful re-entry of Starship. That’s another significant milestone.
But it's not really MVP because a lot of the raw cost/limiting factors of cargo Starship will be in Super Heavy where the vast majority of the engines are. The numbers people have been playing with look pretty comfortably like expended SS+recovered Super Heavy might well end up cheaper in terms of $/kg then F9, and at any rate the raw increase in payload volume and weight means it can do stuff F9 just can't at all. SpaceX can self-bootstrap here and accept the risk thanks to Starlink, so once they can get SS reliably to orbit and recover SH, that's probably enough to make testing at least somewhat pay for itself while they work on recovering SS.
Of course, maybe they nail it on the first reentry attempt! But being able to make money doing launch and have recovery be a bonus while the kinks get worked out is exactly what they did with F9 and I think would be a pretty good place to be in.
