Year 3, day 92.

Returning to our unscrewed program, we set our focus back towards Minmus. Before we send Kerbals there, we need to know a little more about the surface of the moon.
This launch returns to our R4 lifter, but with a new, liquid hydrogen-based upper stage. This gives the rocket just enough extra performance to perform this mission.
