Just going to throw this here in case anyone else is struggling to use the #Tsiolkovsky #RocketEquation to find the #mass of #RocketFuel required for a burn where you know Isp, g0, ∆v and m0. Took me may too long to figure this out, but I need it for a #kOS #kerboscript program I'm writing for a #circularization of #orbit script in #kerbalspaceprogram.
