    Is Starship still aiming for launch cost below $1.5M, out of which ~$500,000 would be fuel/propellant cost?

    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.

    Tak držme pěsti :)

    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.

    About 2 secs after starting engines, martyte covering concrete below shattered, sending blades of hardened rock into engine bay. One rock blade severed avionics cable, causing bad shutdown of Raptor.
