The original procedural concept for a moon landing was a single spacecraft that would act as both lander and mothership however scientists quickly figured out in the 1950s that this would require an extremely powerful launch vehicle for such an ambitious payload. However nothing is too ambitious for the Sarnus V and here is my answer to the original Apollo LUNEX (Lunar Direct Ascent) concept.

The Kane MUNEX (Munar Direct Ascent) is an alternative to the Munar Orbit Rendezvous concept used for the Kane CSM/Sina MEM by combining the functions of both vehicles into one much larger one. The major benefit to this is that rendezvous and docking is unnecessary and can lead to considerably shorter missions. Your kerbonauts don’t need any prior rendezvous or docking practice which simplifies your mission profile considerably.

However there are a couple of drawbacks and additional difficulties in the Direct Ascent approach. The first is that the lander is fairly tall and more unwieldy compared to the Sina MEM. You are also placing all your eggs in one basket if something goes horribly wrong. Since most of the spacecraft is dedicated to having enough fuel for the orbital insertion burn, the descent, the ascent and the TKI (Trans Kerbin Injection) burn there isn’t much room for additional equipment for munar exploration. There is also a steeper learning curve and less margin of error although there should be 200-300 dv extra fuel for trajectory adjustments.

The Kane MUNEX spacecraft is divided into three segments: Command Module (which is detachable), Service Module (which is not), and the Engine/Lander Module which is, by far, the largest part of the craft. The fuel is housed in the SM and ELM while the SM also houses additional instruments and an array of fuel cells. The Kane MUNEX, like other Kane spacecraft, has no solar panels so your sources of powers are several different fuel cells I have included.

The ascent profile is pretty simple and is actually easier than the standard Sarnus V-A11 ascent since this variant of the Sarnus V is a bit shorter and easier to control. The first stage should get you into space and either decoupled immediately if your current apogee is below your desired parking orbit or decoupled around 50-60km. The second stage may be required to finish your initial ascent in some cases but it will also be used for orbital circularization and the TMI (Trans Munar Injection) burn. The third stage is part of the Kane MUNEX spacecraft and is used for the rest of the mission.

The CSM detaches from the rest of the spacecraft which you should do just prior to re-entry while re-entry and landing is pretty straightforward. I have reduced the weight of the heat shield but there should still be plenty of protection regardless of how sharp your re-entry actually turns out to be.

Built in the VAB in KSP version 1.2.2.
