The Absurdly Energetic Munar Impact Challenge

[N2maniac]

My way of doing this:

And with a little effort it can be done. Behold:

Final Stats:

18.7 tonnes

21890m/s

0.5*18700kg*(21890m/s)^2 = 4.480TJ

4.480TJ / (4.184TJ/ktTNT) = 1.071ktTNT

All stock parts except for Mechjeb command module.

I would like to note that aiming it at the Mun is not easy, but careful calculations and timing will do it. Of my 3 ships launched for this mission, 1 ended up off course (math error, oops), 1 missed the Mun (something wrong with my position estimate of it), and 1 hit (after some last minute orbital maneuvers to actually impact).
