All I was trying to answer was how much energy the command module needed to dump & comparing it with the energy in the launch vehicle. In particular I wasn't trying to answer how large a vehicle you'd need to do a powered descent which is much more complicated (and I'm not disagreeing that you'd need almost the same fuel!) | |

| Aug 17, 2020 at 16:45 | comment | added | jumpjack | I don't think that calculating energy of kerosene is the right method, not to talk about just taking into account first stage. We need to know the final kinetic energy impressed to the capsule at the moment of TLI, because this is the whole energy that it will carry when coming back. And probably also potential energy due to altitude must be taken into account (not sure). | |
