Why are heat resistant tiles laid along the surface of spaceships ?
Solution,
Heat resistant tiles are laid on the surface of the spaceships to protect it from high temperature exposure which could damage them instead. The spaceships encounter this high temperature when they are in the earth's atmosphere or when they enter the earth's atmosphere (in case of re-entry spaceships). These heat resistant tiles are ceramic matrix composites (CMCs) and Carbon-carbon composites coated with thermal barrier (TBC) coatings. These tiles are very light and have a very low thermal conductivity.
