Today we’re getting up close and personal with SpaceX’s Raptor 2 engine with Elon Musk. We get into all sorts of details on this engine including how exactly it’s been upgraded and simplified compared to Raptor 1.

This video has a ton of fun details on some fairly technical stuff, so be sure and watch my "Why don’t rocket engines melt" video - https://youtu.be/he_BL6Q5u1Y - so you know what we’re talking about with some of the cooling techniques as well as my video on engine cycles - https://youtu.be/Owji-ukVt9M - so you understand how the Raptor’s full flow staged combustion cycle works and why it’s advantageous!
