In this episode, we break down:  Why liquid cryogenic hydrogen is both an incredible and deeply frustrating rocket fuel How Artemis I scrubbed three times in 2022 due to hydrogen leaks The forgotten history of the \u201cSummer of Hydrogen\u201d (1990) during the Space Shuttle era Why SLS inherits many of the same strengths \u2014 and weaknesses \u2014 as the Space Shuttle What this means for Artemis II launch timing in 2026 Hydrogen rockets are powerful, elegant, and environmentally cleaner \u2014 but they are also notoriously fickle.  If you want to understand why scrubs are normal, why patience is required, and why Artemis II will eventually fly, this episode is for you. #Artemis2 #NASAArtemis #SpaceLaunchSystem #ArtemisScrub #TodayInSpace We'd like to thank our sponsors: AG3D Printing (go to ag3d-printing.com to learn more &amp;amp; start 3D printing today!)
