Not going to lie, I found your back and forth interesting (and mostly sided with the other person), but the argument was lost for me when they attacked you directly.
You are right, SpaceX brought down costs (in dollars) to move mass into space which has opened many new doors. We can argue and disagree about what the broader and long term costs and outcomes of that change might be, but I didn’t get the feeling you were being a fanboy or unreasonably lavish in your praise.
Thank you for writing this response. My general thoughts on hydrogen for rocketry have been that it doesn’t seem worth the trouble (temps, leaks, storage, etc), but I hadn’t considered the environmental or future angles. I’m not convinced that it’s the right choice now, but thanks for giving me something to think about.
No worries. Tbh I kind of jumped on a hydrogen rant, that was all I wanted to talk about, rather than SLS as a whole. I agree we need NASA making things for space, we definitely don’t want SpaceX to be the only player. However it bears mentioning that NASA have also contracted SpaceX to make their moon rockets, in exactly the same way they contract Boeing and others (the only difference is SpaceX already had a suitable rocket in development). So there is no sign of NASA rockets going away, if anything they have more suppliers to choose from.
Hydrogen also does have its place in combustion, and it’s good that there’s some development in this area. However, as someone who works in the electricity industry, adjacent to hydrogen ballooning into the energy markets, I’m intentionally wary of development as much of it seems to be pushed by those looking to sell more hydrogen using disengenuous claims about the reality of it being green.
Remind me again, where is SLS taking off from? Who’s the one not being honest in their argument here?
Wow. You’re not worth speaking to.

Kudos for walking away from the conversation.
