Will the end of the Delta rocket mean an increased price for Centaur and SLS? The Delta program had continuous funding irrespective of launch to support things like the liquid hydrogen supply chain. Centaur is a much smaller rocket, and SLS launches, to a first approximation, never. So who is paying to maintain all the hydrogen trucks, tanks, liquefiers?
Hydrogen itself is a fairly common industrial chemical, but my impression (maybe wrong) is that liquid hydrogen is rare and weird.
@wikkit would you mind if I ask exactly your question on the Space Exploration StackExchange? I'd credit this toot, and let you know if it gets an answer.
@ChateauErin That's a good point, I should put a license on this account. It's probably CC-BY, because I'm not nice enough to be PD? But by all means, repost anything of interest.
@wikkit sorry to say that I'm way too lazy to check for a license and would probably ask you every time, but I hope not to ask you often enough to bother you. :D
