Re: Clearing stage zero is again the primary aim...
it will uck this dust into its rockets basically destroying them when the dust melts inside
don't worry, this think will never make it to orbit, even less so to the Moon.
Why ? Look at the flight profile: it burnt ~3minutes of the first stage, at which point it reached 7000m altitude and 2000km/h. For the same time, a Soyouz or Falcon or Ariane reaches 70 000m altitude and 8000km/h. (approximately, didn't look up the exact numbers again).
Also, this doesn't make sense engineering-wise : no sane person would make a new rocket with new engines with new cycle with new ergols with new materials with new architecture, too many things that can go wrong and you'll not know what went wrong. If they really knew what they're doing they'd make a Falcon-like rocket with Raptor engines and Falcon upper-stage to minimize the number of unknowns. The Falcon is so successful because they use the same proven ergols and architecture as developed for Apollo and Soyouz. Falcon is an incremental evolution of proven and existing engineering, while Starship is a Hollywood phantasm. We'll have hover-boards and laser-sabres before Starship makes it to the Moon.
