In Kerbal Space Program you can recreate the Apollo missions using the stock parts.
Apollo 11
An awesome Apollo 11 tutorial is located at Apollo 11 tutorial. Follow the instructions, but I have made some changes for easier operation.
Notes
Construction
I have added the Heat Shield (2.5m) to the bottom of the top command module just in case the command module does not have heat shield.
Added the Kelus-LV Bay Mobility Enhancer (retractable ladder) under the hatch of the lander for easier return after Munwalk.
Added solar panels to the lander and the service module.
Disabled the yaw, pitch, and roll functions of the RCS thrusters on the command module and all thruster blocks to Save on monopropellant
Take EV Fuel Cylinders from Cargo with you in the command pod, the lander, and on the Kerbals instead of parachutes to extend the length of EV operations.
Flight
Towards to Mun
While the Command Module and the Lander are approaching the Mun we want to use the Command Module’s engine. When we dock the Command Module to the Lander, the staging changes, and activates the Lander’s engines. The fuel gages indicate the active engines. In this configuration during the Mun orbit insertion burn the Lander’s engines will work against the Command module’s and make it very difficult to achieve a good Munar orbit.
Right-click the Lande’s engine in the staging block and click the Shutdown Engine button. If you have multiple Lander engines, do it for all engines.
In Mun orbit
After circularizing the Mun orbit, before the lander separation, stage one more time to activate the LEM main engine.
Landing on the Mun
As you descend, set the SAS to retrograde to keep the lander upright and be able to always reduce the speed with the main engine without the need for orientation adjustment.
On the Mun
In case you run out of monopropellant in your EVA Jetpack, plant a flag under the hatch, so you can climb on it and get back to the lander.
Take off from the Mun
To get the heading of the command module, turn it to prograde. This is the direction you need to get into orbit with the lander for the rendezvous.

There are mods for Kerbal Space Program 2 which make space flight much easier. We will not use “cheats”, these mods display the necessary information for easier maneuver node configuration, manual burn execution, and docking. We recommend the following mods:
Maneuver Node Controller
Docking Alignment
Micro Engineer
Launch to orbit around Kerbin
Mun
As the Mun’s orbital plane is parallel to the equator of Kerbin, launch the vessel Due East (90°) with 0 ° inclination.
Match the target planet’s inclination
While still in Kerbin orbit, match the plane of the target planet’s orbit.
We will stretch our orbit to reach the Mun’s sphere of influence.
Set the control point
As the lander is attached to the command module, make sure you use the command module’s engine, and control the joined spacecraft from the command module. If the lander can is set as the “Control From” location, the burn will slow down the combined space craft and it will crash into Kerbin, instead of speeding it up towards the Mun (been there, done that).
Right-click the pod of the command module and select Control From Here
Create the injection burn
Click the orbital path and select Create a Maneuver Plan
Click the Mun and select Focus to keep the Mun in the center of the screen
Right-click the Mun Periapsis to keep the value displayed
Using the prograde vector and moving the maneuver, plan an orbit to set the Mun Periapsis to around 10 – 15 km
The planning is done at the current Mun location, but the real encounter will happen at another location further down the orbital path of Mun.
Start the burn and stop early before your orbit reaches the orbit of the Mun. Delete the maneuver to see the real values on the map. Continue the burn with the low throttle, and when the Mun periapsis node appears on the map, stop the slow burn, and right-click it to keep the value displayed.
Continue the low throttle burn to fine-tune the orbit, and watch the number of the Mun periapsis to stop at the planned value.
Capture orbit
Create a maneuver at the periapsis, and use the retrograde vector to slow down, and bring the apoapsis closer to the Mun for a circular orbit.
Warp ahead to the maneuver and execute the burn. Fine-tune it to reach the planned apoapsis.
Landing on the Mun
To land on the Mun, create a maneuver with a negative periapsis to hit the surface a few kms further away, so you can slow down and start a steeper approach to avoid hills.
Place the lander in a 15 km circular orbit
Create a maneuver with a retrograde burn to set a -60 km periapsis
Move the maneuver to hit the ground a few miles further downrange with three clicks on the right side maneuver time mover button
Adjust the latitude with the Normal and Antinormal vectors
After the deorbiting burn, set the SAS to retrograde to be able to slow down the craft with the main engines. If the throttle is too sensitive, set the Thrust limiter to a lower number
Orient the space craft
During landing and takeoff it is very important to know which way the lander faces. Unfortunately, if the Lander Can window faces upwards during deorbit and forward when the craft is in vertical direction, as during the real Apollo missions, the WSAD controls tilt the craft in the opposite direction as expected. If we want our kerbonauts to be able to use the window, we need to adjust to this. We can rotate the lander 180 degrees to make maneuvering easier, but we need to remember which way we landed. To be able to rendezvous with the command module, we need to take off in the same direction as we landed.
Land the space craft
Use the altitude above ground to avoid hitting hills and highlands
Click the altitude gauge of the Nav Ball to switch to ground altitude or
Activate the Micro Engineer mod and open the Surface panel
Landing
At the time of touch down keep the vertical speed below 12 m/s to protect the landing legs.
EVA on the Mun
The Kerbonaut jetpack is very powerful, to be able to lift the Kerbal in a high gravity environment. It is too powerful in the low gravity of the Mun. To be able to make slow, precise movements, right-click the Kerbonaut, and set the Jetpack trust to 50%.
Take off from the Mun
Take off
As we already mentioned above, to be able to rendezvous with the command module, we need to take off in the same direction as we landed.
Hover above the Command Module with the mouse to check the altitude of the command module orbit
When the Command Module is almost overhead, take off and tilt the craft forward in the same direction as it landed
Burn the main engine until the apoapsis reaches the Command Module orbit altitude. MAke sure to keep the correct direction.
Circularize the orbit
As we already did it in Kerbin orbit, create a new maneuver in the apoapsis to bring the periapsis to the same altitude.
Before you undock the lander transfer the crew and resources to the Command Module
Transfer the crew
Use the Kerbal Manager to transfer the crew
Transfer the resources
Use the Resource Manager to transfer the remaining resources from the lander
Expand the Monopropellant section to transfer the RCS fuel and electric charge
Select the OUT button on the lander and IN button on the Command Module storage, and click START
Expand the Methalox section
Select the OUT button on the lander and IN button on the Command Module storages, and click START
Going home
To escape the Mun’s sphere of influence, and return to Kerbin, we need to increase the apoapsis retrograde relative to Kerbin.
Create a maneuver on the prograde side of the Mun, to increase the apoapsis with a prograde burn until Mun Escape is displayed.
At this point the Kerbin periapsis is usually still too high for re-entry.
Right-click the Kerbin Periapsis to keep it displayed, adjust the time of the maneuver to minimize the Kerbin periapsis, and adjust the prograde vector to set the periapsis to around 35 km.
During the burn, the actual Kerbin periapsis will appear and display the changing value. With low throttle continue the burn until the Kerbin periapsis reaches 35 km height.
To attach parts to spacecraft in orbit you can transport the parts in the cargo hold of your vessel, dock to it and do the upgrade.
Take a ladder
Besides the part, take a mobility enhancer (ladder), so the Kerbal has something to hold on to, and a junior docking port with you to temporarily dock the vessel.
Crew
For construction in orbit, you need an engineer on board.
EVA
Make sure the astronaut only has the necessary equipment in their inventory. By default they have a parachute and an EVA pack in this order. If you take them outside for an EVA they take the parachute, and if they let go the hatch, lost forever. For EVA gave them only the EVA pack.
Right-click the module the astronaut is in
Move the EVA pack to the first place in the inventory
The astronaut has access to inventories in closeby vessels, so keep both vessels close to each other.
You can practice orbital construction on the launch pad and the runway.
Make sure the Kerbal in EVA is in a stable position, preferably grabbing one of the vessels, as during construction you cannot control them, and they can drift away.
Click the Build icon on the toolbar on the left side.
Grab a part from the inventory and place it on the target vessel.
Rotate the parts with the A S D Q W E buttons, use the left Shift for fine rotation. Hold Alt to snap to nodes on the vessel.
