No straight path for hot gas to accelerate through the gaps

I thought you were going with transpiration cooling so you wouldn't have to replace them after each flight. Will this system be the backup for the transpiration cooling, something in addition to the transpiration cooling, or a replacement to it.

Transpiration cooling will be added wherever we see erosion of the shield. Starship needs to be ready to fly again immediately after landing. Zero refurbishment.
Just spoke with sheriff....today’s test hop at SpaceX Boca Chica has been scrubbed due to weather and is postponed until 10am - 4pm tomorrow.

Yes. Sensitive propulsion & avionics remained dry. Great work by SpaceX Dragon engineering team. Major improvement over Dragon 1.

Some challenges with ice formation in the cryogenic propellant prevalves. Hopefully overcome soon.
