Revision as of 15:03, 23 March 2013

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 make a rocky grave for Kerbanauts. 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

Steps

Step 1 - Getting MechJeb

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

Suggested mods to find include:

  • MechJeb Command Prods & Probes [2]. This extra mod enables MechJeb on all the command pods.

Step 2 - Building the Mun rocket

Since MechJeb doesn't use much fuel you may use Kerbal X which is included with KSP, and add two extra Rockomax X200-32 Fuel Tank at the the middle section at the bottom. If you don't have the MechJeb Command Prods & Probes you need to add a MechJeb AR202 case.

Step 3 - Launch the rocket using Ascent Autopilot

Open the Ascent Autopilot from the MechJeb menu. Make sure the following settings are as listed: Orbit altitude should be 100km.Auto-throttle is checked.Auto-stage is checked(do not check if you are unsure of the staging setup).Auto-warp is checked(to speed time up). Press engage and hit the space bar to launch.

Step 3 - Going to the Mun

  • After you entered Kerbin orbit close the Ascent Autopilot and open the Orbital Operations from the MechJeb menu.*In the Orbital Operations click on TRANS and select Mun. MechJeb then will fast forword to the Mun injection burn point and fire the engines.*If you run out of fuel on the first stage press space twice to start the engine.*After the burn has complete click on WARP and select periapsis and press warp.*After you finish warping, click on CIRC and click Circulaize. This will put you in the Mun orbit.

You are now in the Mun orbit. Follow step 4 to land on the moon or follow step 5 to return to Kerbin.

Step 4 - Land on the Mun

  • Once captured by the Mun, Retro-burn to first counter-act the slingshot, past, slowing into an eliptical orbit.
  • Continue retro-burn to place Periapsis on the surface of the Mun.
  • From here, several large burns, or one long gentle burn will be required to negate your horizontal and vertical speed.
  • Aim to hit the surface land with less than 5 m/s vertically and less than 3 m/s horizontally to ensure a safe landing.
  • Keep SAS on, to stabilize the vehicle on landing.

Step 5 - Return to Kerbin Optional

  • If your rocket has the fuel to reach the Mun's escape you can most probably return to Kerbin.
  • First fire your rockets but monitor your map view for the point at which you reach the Mun's escape velocity and cut the rockets.
  • Once in the gravity well of Kerbin burn to lower Periapsis to lower the 70,000m.
  • Warp to your Periapsis. Lower than 70,000m the drag from the atmosphere of Kerbin will lower your orbit without the need for additional burns.
  • 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.)

Finishing word

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