Thanks for that link. I was surprised that the fuel costs for the first stage was quoted to be only $200-300k. I had to look up the engine technology and saw that they are LOX/RP (kerosene). That makes sense... it's a return to the Saturn V technology and what the Russian have never stopped using..

Jet fuel? Ithiught they were all hydrogen gas. Didn’t know that....🤔
