Today, I managed to get into orbit around Minmus (which I've never done before) and, thanks to my recently-acquired MechJeb, even land on it (somewhat awkwardly, I might add - due to not having landing legs or any stabilising feature, my rocket managed to fall on its side). Richford Kerman explored the surface for a bit and put a flag on the landing site. Despite the fact that the whole rocket was on its side, I used Minmus' very low gravity to my advantage and was able to use the surface as a runway, eventually getting back into orbit. Surprisingly enough, I still had enough delta-v to transfer back to Kerbin and even position myself for a landing. However it was only then did I realise I made the rather unfortunate mistake of not including parachutes in my spacecraft and I did not have enough fuel left to fire my retrorockets, so everyone crashed and died. Thank goodness for quick saving before landing on Minmus, I guess. In the end, I might not have actually landed on Minmus (paradoxically speaking, of course), but at least I successfully got my Kerbals to Minmus orbit and back. Which I guess is quite something.
