Why Starting A Rocket Engine Is So Hard!

Today we're going to do a deep dive on how exactly you start a rocket engine. We'll cover pretty much everything from a simple solid rocket motor, to all the intricacies of liquid fueled rocket engines. We'll go over thermal conditioning the engine, the spin up process, the scary transient regions, and the actual ignition of the propellants. Then we'll talk about some of the extra challenges like starting a rocket engine in space and then we'll go step by step through the RS-25's startup procedure.
