The insulation prevented heat transfer to the underlying orbiter aluminum skin and structure. These tiles were such poor heat conductors that one could hold one by the edges while it was still red hot.

While the re-entry surface heating of theOrbiter was predominantly convective,sufficient energy in the shock layerdissociated air molecules and provided thepotential for additional heating. As the airmolecules broke apart and collided with thesurface of the vehicle, they recombined inan exothermic reaction. Since the surfaceacted as a catalyst, it was important that theinterfacing material/coating have a lowpropensity to augment the reaction. Atomicrecombination influenced NASA’s selectionof glass-type materials, which have lowcatalycity and allowed the surface of theOrbiter to reject a majority of the chemicalenergy. Engineers performed precise arcjet measurements to quantify this effectover a range of surface temperatures forboth oxygen and nitrogen recombination.This resulted in improved confidence in theThermal Protection System.

The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the searing 1,650 °C (3,000 °F) heat of atmospheric reentry. A secondary goal was to protect from the heat and cold of space while in orbit.

Spacecraft re-entry is tricky business for several reasons. When an object enters the Earth's atmosphere, it experiences a few forces, including gravity and drag. Gravity will naturally pull an object back to earth. But gravity alone would cause the object to fall dangerously fast. Luckily, the Earth's atmosphere contains particles of air. As the object falls, it hits and rubs against these particles, creating friction. This friction causes the object to experience drag, or air resistance, which slows the object down to a safer entry speed.

This is as the out layer of the space ship is made of ceramic tiles, which is a thermal insulator, so heat cannot be conducted to the interior of the space shuttle easily. Thus, the interior of the space shuttle would be insulated.

# data[].attributes.body
The ceramic is an poor conductor of heat, therefore the space shuttle will not be too hot. There are spaces in between the ceramic tiles and thus allows room for expansion and contraction when entering the Earth's atmosphere.

The tiles are thick and conduct heat slowly which allows the inside of the space shuttle to remain cool :)
