===Step 1 - Obtaining MechJeb===
Get the The Intrepid SLS Rocket from [http://forum.kerbalspaceprogram.com/showthread.php/3396-Industrial-Flames-Explosions-Inc-Version-1-4-2-Now-Available! here], or a number of other modded parts to make your journey easier.
 
  
Suggested parts to find include:
+
Get MechJeb. [http://http://www.curse.com/ksp-mods/kerbal/220221-mechjeb].
* Larger Solid Rocket Boosters
+
MechJeb is an autopilot plugin that allows you get into orbit, and go to the Mun in the fastest and most efficient way possible.
* Lunar Landing Module (LEM/LM)
 
* Larger Liquid fuel tanks
 
  
===Step 2 - Launch the rocket normally===
+
Suggested mods to find include:
 +
*MechJeb Embedded [http://www.curse.com/ksp-mods/kerbal/221109-mechjeb-embedded-universal]. This extra mod enables MechJeb on all the command pods.
  
Fly up to about 15,000 Metres vertically. At this point, begin "the tilt" East or West. Once about about 65-70,000m, you are out of the atmosphere and can transfer your upwards energy into east-west speed.

===Step 2 - Building the Mun rocket===
  
===Step 3 - Go to the [[Mun]]===
+
Since the Kerbal X is already a very capable rocket, we will use that for our trip to the Mun. However, we must make some additions to allow [[Jebediah Kerman|Jeb]] to come home.
  
Difficult on first glance, a rule of thumb will help you get there.
+
Add a [[Rockomax Brand Decoupler]] beneath the lander's engine. Add a [[Rockomax Jumbo 64 Fuel Tank]], and a [[RE-I5 "Skipper" Liquid Fuel Engine]] beneath that.
  
* Wait for Mun-rise to finish from an approx. 100,000m orbit

That should be enough for a round trip.
* Burn to raise your apoapsis to between 11.5 and 12.5 million.
+
 
* Get captured by the Mun's gravity.
+
If you don't have the MechJeb Embedded mod you will need to add a MechJeb AR202 case. If you put it on the lower stages, the upper stages will '''NOT''' have MechJeb capability. Therefore, you should put it on the [[Command module|command module]].

Open Ascent Guidance from the MechJeb menu.

* Go to the [[Map view|map view]], and set the Mun as your target.
 +
* In the Maneuver Planner use the arrows to select 'Hohmann transfer to target'. Then, click 'Create and execute'.

You are now in the Mun's [[Sphere of influence|sphere of influence]]. Close Maneuver Planner. Go to step 4 to land on the moon or skip to step 5 to return to Kerbin.

Make sure the following settings are as listed:

* Orbit altitude should be 30&nbsp;km.

* Auto-throttle is checked.

+
* Auto-stage is checked (do not check if you are unsure of the staging setup).
* With luck you will have some fuel left that can be used for canceling extra vertical and horizontal velocity before the opening of your parachutes or a power landing. (Parachutes are much easier than power landings on Kerbin.)

Press Engage autopilot to take off.

This article is currently undergoing a major expansion or revamping. However, you are free to help in the construction of this page by improving it.

Landing on the Mun is no easy task. With a reasonable gravity well, and no atmosphere, the rocky natural terrain makes a rocky grave for Kerbonauts. This tutorial provides tips on how to land on the Mun using MechJeb.

Specifications

  • Length: 5–10 minutes
  • Difficulty: Moderate
  • For version: 0.19 and above (tested on 1.0.5)
  • Mods Required: MechJeb

Steps

Step 1 - Obtaining MechJeb

Get MechJeb. [1]. MechJeb is an autopilot plugin that allows you get into orbit, and go to the Mun in the fastest and most efficient way possible.

Suggested mods to find include:

  • MechJeb Embedded [2]. This extra mod enables MechJeb on all the command pods.

Step 2 - Building the Mun rocket

Since the Kerbal X is already a very capable rocket, we will use that for our trip to the Mun. However, we must make some additions to allow Jeb to come home.

Add a Rockomax Brand Decoupler beneath the lander's engine. Add a Rockomax Jumbo 64 Fuel Tank, and a RE-I5 "Skipper" Liquid Fuel Engine beneath that.

That should be enough for a round trip.

If you don't have the MechJeb Embedded mod you will need to add a MechJeb AR202 case. If you put it on the lower stages, the upper stages will NOT have MechJeb capability. Therefore, you should put it on the command module.

Step 3 - Launch the rocket using Ascent Autopilot

Open Ascent Guidance from the MechJeb menu.

Make sure the following settings are as listed:

  • Orbit altitude should be 80 km.
  • Corrective steering is checked.
  • Autostage is checked (do not check if you are unsure of the staging setup).
  • Auto-warp is checked.
  • Prevent overheats is checked.

Press Engage autopilot and hit the space bar to launch.

Step 3 - Going to the Mun

  • After you have a stable orbit, close Ascent Guidance and open the Maneuver Planner from the MechJeb menu.
  • Go to the map view, and set the Mun as your target.
  • In the Maneuver Planner use the arrows to select 'Hohmann transfer to target'. Then, click 'Create and execute'.
  • If you see your landing spot on the Mun or just want to land anywhere, skip to Step 4.
  • After you enter the Mun's Gravity well, wait until you reach your periapsis, then burn retrograde. Cut throttle when it is no longer an escape orbit (this is signified by the prescence of an apoapsis).

You are now in the Mun's sphere of influence. Close Maneuver Planner. Go to step 4 to land on the moon or skip to step 5 to return to Kerbin.

Step 4 - Land on the Mun

  • After you've entered the Mun's sphere of influence, open the Landing Autopilot from the MechJeb menu.
  • Ensure "Deploy Parachutes" is UNchecked.
  • Press Select target on the map and choose where you want to land.
  • Press Land at target. Alternatively, if you just want to land somewhere, press Land somewhere.
  • MechJeb will warp to the deorbit burn point.
  • Warp till 20000m (don't warp more than 3x).
  • Extend the gear once it says executing braking burn.

You have now landed on the Mun. You can now extend the ladder and EVA (optional). Go to step 5 to return to Kerbin.

Step 5 - Return to Kerbin

In Career Mode, this is no longer optional unless you plan on sending a rescue mission.

Open the Ascent Autopilot from the MechJeb menu.

Make sure the following settings are as listed:

  • Orbit altitude should be 30 km.
  • Auto-throttle is checked.
  • Auto-stage is checked (do not check if you are unsure of the staging setup).
  • Auto-warp is checked.

Press Engage autopilot to take off.

After you have achieved a stable orbit around the Mun, pull up the Maneuver Planner again.

  • Cycle through the arrows until you see "Return from a moon" then click "Create and Execute"
  • Once you are back in Kerbin's gravity Well, close the Maneuver Planner and open the Landing Assistant.
  • Ensure "Deploy Parachutes" is CHECKED, unless you want to land retro-rocket style.
  • Depending on how much fuel you have, pick KSC, a landing point, or just "Land Somewhere." You may have to ditch your landing selection somewhere along the line if you run out of fuel.

Flying to Mun is a great achievement and one which all aspire to accomplish. This guide should help you to achieve your goals and begin to look at even more challenging possibilities in Kerbal Space Program!
