@Erdayastronaut @rweb11742 Merlin is a strong local maximum design, but kerosene is suboptimal fuel, no matter what you do. What matters is cost per ton to Mars. CH4 is the only choice imo. Important: O2/CH4 allows OF ratio of ~3.5 vs ~2.5 for kerosene, so ~78% of propellant is oxygen. — PolitiTweet.org

@PPathole @Erdayastronaut @rweb11742 Yeah, looks like marginal cost of launch will be less than $1M for more than 100 tons to orbit, so it’s mostly about fixed costs divided by launches per year — PolitiTweet.org
