Why don't rocket engines melt? How engineers keep engines cool

About

Rocket science. A term we all use to describe something incredibly difficult. Trying to grasp all of the concepts involved in rocket science can be incredibly intimidating. My name’s Tim Dodd but I'm better known as the Everyday Astronaut. Recently I fell head over heels in love with spaceflight. My appreciation and curiosity for the subject grew into an obsession. Before you knew it, all I wanted to do was learn more and more... the more I learned, the more I wanted to share what was making me so excited. But as someone who dropped out of college and has no technical background or degree… I really felt unqualified for the job of explaining rocket science to anyone. But the fact of the matter is, if I can learn this stuff, anyone can. Rocket science is awesome, and you don’t need to be a rocket scientist to be excited. Everyday Astronaut. Bringing space down to Earth for everyday people.
