The guy: On the outside of the thermal shield it is 1500 degrees, and on the other side it is just about room temperature. What is he smoking? @_opreturn
Good example. Melting T of iron is 1500 C. If there is any iron in the lander, it should have melted. Have you seen the vape and the truck vid? The 1500 C air comes around the shield .
"If there is any iron in the lander, it should have melted." Why? Heat is at the shield. For example ceramic brick, one end +1300 C, you can hold it at the other end 5 cm away
Dude you can go watch the launches with your own two eyes. Of course you're so deep in your Cartesian delusion that you probably wouldn't even believe your own eyes so it don't matter.
I'm not sure that could be a replacement for air conditioning lol. Even if it were it would probably cost more than your house to add. The composites are very expensive.
Take a blowtorch to a old space shuttle tile and you'll find the temperature gradually becomes lower the farther into the material you go, and the other side is far cooler.
The thermal shield is meant to deflect heat. The material is specifically chosen for the fact that it does not conduct heat efficiently through the material.
