Experts Warn Starship Heat Shield Tech Is a Dead End for Rapid Reuse

SpaceX successfully launched its Starship vehicle on Friday and appeared to demonstrate important and credible steps toward fulfilling the massive rocket's immense promise. As soon as the vehicle's next flight, Starship could go orbital, begin delivering satellites into space, and potentially return to the launch site to be 'caught' by the tower.

All of this is impressive engineering on a gigantic scale. But despite the marked progress with the 13th test flight of Starship, one key issue—probably the key issue when it comes to Starship's future—remains unresolved.

This concerns Starship's heat shield, the roughly 18,000 ceramic tiles that protect the vehicle's underbelly during its fiery return through Earth's atmosphere. And some experts say SpaceX's current approach may not get Starship to its ultimate goal of flying frequently, at low cost.
