I've been around online since the earlier usenet days when you had to have some chops to know what usenet is (was), and how to get on it. Mastodon right now feels a bit like the good days of usenet, there's some of the same vibe. Interests: bike maintenance, ebikes, orchids, cymbidiums, weird succulents, gardening in general, security engineering, current events, congressional shenanigans, courthouse shenanigans, US and european politics. #slavaUkraini #nobridge

The state of the art of chemical liquid rocket fuels for main propellant has *not* advanced somewhat--they're still using fuels discussed in the book, including the one that Clark's lab eventually determined was slightly the superior, extra-refined kerosene, which became RP1, which is used today in Space-X falcons and heavies. Methane, extensively discussed, is used in Space-X starship engines. SLS and the space shuttle use(d) hydrogen, again extensively discussed. Over 20 years they pretty much wrung dry the high energy compounds that can be created with the peridioc table we have. Iteration and improvement in rocket engines, yes. Main stage fuels, no.
I guarantee you every english-speaking professional working with rocket engines and fuels has read this book, and first edition copies are treasured and are selling for over $250 last time I looked. But it's your list, do as you wish, I will not bother you further.
