I have calculated several interesting scenarios and recently found out that if you have Xenon and an MPDT ( magnetoplasmadynamic thruster ) drive you can actually reach the famous ” ludicrous” speed.
For this 3rd stage ( or after the third stage ) it can accelerate to an almost 1 000 000 km/h speed ( with no fuel to brake ). It needs also 200 m2 solar panels ( origami like in the fuse ).
