      Natural Gas rockets? What a small step for man, massive step back for mankind.

      Why do you dislike methane as a fuel? Also, in case you were unaware, as a side note, SpaceX’s newest rocket, which is currently under active development, Starship and Super Heavy, uses methane as a fuel.

        Okay thanks, I like it EVEN LESS NOW. We have better rocket fuels which degrade into water vapors. Using Natural Gas rockets is the environmentally unfriendly option that make corporations more money.

          We have better rocket fuels which degrade into water vapors.

          Which fuels are those? Also why would one want their rocket fuel to degrade? I can see fuel storage issues with that. Furthermore, keep in mind that the reaction of CH4 and O2 (combustion) creates H2O (water) and CO2. The only fuel that I’m aware of that creates only water when it’s combusted in O2 is H2 (hydrogen). An issue with hydrogen as a fuel, when compared with methane, is its mass ­— lower exhaust mass lowers the specific impulse.
