Starship is starting to be a very long and not so cheap project though that doesn't seem to be making significant iterative improvements - Rockets are still exploding regularly where you'd expect them to have moved beyond that phase.

Sorry, what? Starship 11 proceeded with a totally nominal ascent, orbit, descent, and powered landing that would end up with it standing on the ground, were it not deliberately landed into water.

What SLS currently has achieved had been achieved by Falcons and Dragons years ago, only way more cheaply and successfully.

No matter what we may think about Mr Musk, SLS is dead end.
