This week on Today In Space...space nerds left Florida disappointed as Artemis II is scrubbed until March — and cryogenic hydrogen does what it does best: leak.
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 “Summer of Hydrogen” (1990) during the Space Shuttle era
* Why SLS inherits many of the same strengths — and weaknesses — as the Space Shuttle
* What this means for Artemis II launch timing in 2026 Hydrogen rockets are powerful, elegant, and environmentally cleaner — but they are also notoriously fickle.
If you want to understand why scrubs for these Hydrogen Rockets are normal, why patience is required, and why Artemis II will eventually fly, this episode is for you.
