      Let me guess. Hydrogen again.

      Edit. I read the article. Yup it’s hydrogen again.

      I find it interesting that a good chunk of the world wants to switch to making, shipping, and burning hydrogen when rocket companies are having issues making valves that work.

      I am honestly worried we end up with a Challenger situation, based purely on the incompetence of the higher ups at this time.

      I’m not suprised, they had issues with hydrogen leaks last time too, and given how infrequently SLS launches it’s not like they get much practice. Hydrogen is the smallest atom on the periodic table; it will leak out of the tiniest hole or gap in the plumbing, it’s notoriously difficult to work with

      So with the recent cold snap in Florida, uh… how are the O rings doing? I will freely admit I’m not 100% on the details but didn’t a similar cold few days lead to the O rings cracking and setting events into motion?
