I think that means xenon, solid fuel, monopropellant, hydrogenium, nuclear and other engines. What I want are kerosene, toxic hypergolics and liquid hydrogen engines, and I make it quite clear, 'diversifying liquid fuels'.

To be honest, I am quite disappointed to hear that there's only methane for the first day. I'd have been looking forward to diversifying liquid fuels for different tasks. Well, I'll wait.

Yes! That's a grest idea!

I mean, the meterial which provides larger m0/mk, is usually more expensive, for example, aluminum alloy vs. stainless steel. Not because the aluminum alloy is lighter, but the aluminum alloy has higher specific strength and specific stiffness.

The more expensive, the better.

Hi！ Looking forward to take a part in early access process. I have a question. Is the aerodynamic of procedure wings based on their shape or not? Does the aspect ratio, root-to-tip ratio, airfoils, etc., really effect the performance of the wings? @Ghostii_Space

the gravity is not a constant in KSP1.

infact, all the planets in solar system were discovered before the first rocket. so...no more planet to be discovered in kerbal system.

I hope KSP2 aerodynamics will be more realistic than KSP1. I have a master degree of aerospace, for me, a viscous fluid and non real air effect hypersonic result will be good. This won't be too difficult for new players, and sometimes can be challenging for senior players, also can banlance the veracity and gameplay. Anyway, aerodynamics levels option will be useful.

Good point.

Can't wait to play KSP2 XD.
