Tutorial:Mun Super Easy
This tutorial will show you the easiest way to land on the Mun and come back. This does not require gravity assist, docking, etc.
Step 1: Build Rocket
The first thing you need is a rocket. This will be a modified Kerbal X. First, load the Kerbal X. Delete the parachute, fins, radial decouplers, and radial boosters. We will delete the capsule later, but you need it on to edit. Place 8 TT-70 Radial Decouplers near the middle of the first stage. Add 8 S1 SRB-KD25k "Kickback" Solid Fuel Boosters on the decouplers. Place Aerodynamic Nose Cones on the boosters. Turn off Symmetry Mode. Now delete the capsule and get a Mk1 Command Pod. The rest of the rocket will turn red. Set it aside. Add a Mk16 Parachute. Now place a FL-T800 Fuel Tank below the capsule and add a T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine below that. Place a TR-18D Stack Separator under that. Add a C7 Brand Adapter - 2.5m to 1.25m under that and connect the rest of the rocket. Add 8 Stratus-V Cylindrified Monopropellant Tanks anywhere on the final stage. Place 4 O-10 "Puff" MonoPropellant Fuel Engines on the same stage and add 4 LT-2 Landing Struts on Cubic Octagonal Struts just above the aerospike. Retract the landing struts, and you're finished!
Step 2: Staging
Direct your attention to the staging controls on the right side of the screen. The first stage should be the RE-M3 "Mainsail" Liquid Engine and the S1 SRB-KD25k "Kickback" Solid Fuel Boosters. Then the Rockomax Brand Decoupler. The second should be the RE-L10 "Poodle" Liquid Fuel Engine. Then the TR-18D Stack Separator. The third stage should be the T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine. FInal stage is the Mk16 parachute.
Step 3: Launch Prep
Now that you have a rocket, select Launch. On the launchpad, hold ↓ so you can see the sky but not the rocket. Time warp until the Mun is full and on the left side of the screen. Activate Stability Assist (SAS). Throttle up, and launch!
