@IAMAL_PHARIUS fair enough. Honestly I need to find one of my KSP autists and ask them about the orbital dynamics here. They of all people would know....

@Diogenese_Shiplap @merchantHelios Escape velocity is fixed, so they probably will do the high speed rail thing like in gundam.

Too costly for us, probably works for them

@merchantHelios @IAMAL_PHARIUS Perhaps the heavy gravity would lead them in a direction not using explosive force to achieve escape velocity.

@IAMAL_PHARIUS @Diogenese_Shiplap also keep in mind if the current data is accurate K2 is almost certainly predominantly an ocean world

@IAMAL_PHARIUS @Diogenese_Shiplap @merchantHelios velocity isn't the problem, it's acceleration ( gravity )

@Diogenese_Shiplap @sickburnbro @IAMAL_PHARIUS @merchantHelios We can actually calculate how much fuel you need for a conventional chemical rocket using the Rocket Equation (Δv = Ve * ln(M0/Mf), where Δv is the change in velocity, Ve is the exhaust velocity, M0 is the initial mass (including propellant), and Mf is the final mass (without propellant). Δv in this case is literally just your escape velocity, which you can calculate by v=sqrt(2GM/r), where G is the universal gravitational constant, M is the mass of the planet, and R is your distance from its gravitational center.

To achieve escape velocity from a planet with 10x earth gravity, your rocket's fuel mass will be roughly the same as the planet's mass. A planet with 6G at sea level would require a few million Saturn Vs strapped together to launch a Mercury capsule into orbit. You might be able to cheat a bit using a fixed-wing aircraft with a nuclear ramjet and then launch your upper stage from there, but that would still be extremely difficult. On a water world where resources are mostly under the seabed and therefore more difficult to access, orbit might be logistically impossible barring gravity manipulation technology.

Thank you for reading my blogpost. Woman images are attached to repay you for your time.

@sickburnbro @IAMAL_PHARIUS @merchantHelios True, but escape velocity gets you in orbit unless aimed at the ground. I know applying all that in one bang won't work, despite Mssr Verne's best math, but yes I oversimplified.

@Armpits @Diogenese_Shiplap @sickburnbro @IAMAL_PHARIUS @merchantHelios Here is a guy launching a rocket in KSP with 10x gravity.
Which this planet does not have by the way as Helios has said its 12m/s vs 10 on earth.

KSP parts are heavier than real world equivalents for balance reasons. The rocket weighs "only" 7000 tons

In any case, your estimate
>your rocket's fuel mass will be roughly the same as the planet's mass.
seems grossly innacurate. I am checking your math and I WILL take away that 👑 react if you are wrong! :peepoGiggle:

masterful display

>no sea planet sex
also, why? I wouldn't want to come back up anyways.

also even in the 10xG case, you can do a space ring elevator to avoid this problem, it's relatively cheap if you put a donut around the equator instead of a counterweight above geostationary. The ring would stabilize itself, the only force on the wires downward would be the weight of the payload. you can put a maglev up there
