> The orbiter itself was slow and expensive to reuse since (among other things) all the heat shield tiles were inspected and 30-100 replaced between each launch.

Worth noting that Starship's heat shield is very similar to the one of the Shuttle. They actually got the manufacturing method from NASA.

That's why I remain very skeptical about the easy refurbishing of Starship. Initially, way back around 2016, the plan was to vent liquids to create a cushion around the ship. That sounded more easily reusable.

Yeah. I think they originally planned to use ceramic tiles only for certain spots and still transpiration cooling for the rest. Then they fully switched to ceramic tiles. In an interview with Everyday Astronaut on YouTube, if I recall correctly, Elon Musk said they first believed the ceramic tiles to be lighter.
