For extra realism, you should totally aim for a retrograde orbit around Mun.

I will be going retrograde. I actually found out around 0.18 or so that if you want your Apollo Style craft to go around the Mun's backside for insertion, you have to go retrograde. I was confused at this, as I thought that surely they would have gone prograde.

If you Don't mind my asking, what mods are you using?

Frizzank Aeronautics and Space Administration (FASA) mod.

The reason they went retrograde was for the free return trajectory. Going prograde would put them at risk of a slingshot into solar orbit if the SPS failed, but a retrograde approach would throw them back towards Earth. It's also much easier for the TEI burn to be going retrograde.

Yeah, I eventually figured this out. I still couldn't replicate free-return trajectory, though.

It's tricky to do, but it's possible. You have to fiddle with both the position and delta-V of your injection burn and it takes a little patience. I always go prograde in KSP though.

Are you going to have the S-IVB slingshot into solar orbit?

nah, I opted for a collision course, as shown early.

Nice. When I did my first Mun missions, which were Apollo-style, I also left the upper stage on an impact course and had the spacecraft adjust away from said course after undocking. This is because I don't like debris. :D

In real life, Apollo 8 through 12 slingshot their upper stages into solar orbit, while 13-17 crashed it into the moon.
