Landing on the Mun is no easy task! With a reasonable gravity well, and no atmosphere, the rocky natural satellite conspres to make a rocky grave for Kerbanauts. This tutorial provides tips on how to land on the Mun using modded parts. Although in reality, from Step 2 it applies to any ship attempting to fly to the Mun.

Specifications

  • Length: 5-10 minutes
  • Difficulty: Moderate
  • For version: 0.13 and above

Steps

Step 1 - Getting the addon

Get the The Intrepid SLS Rocket from here, or a number of other modded parts to make your journey easier.

Suggested parts to find include:

  • Larger Solid Rocket Boosters
  • Lunar Landing Module (LEM/LM)
  • Larger Liquid fuel tanks

Step 2 - Launch the rocket normally

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 3 - Go to the Mun

Difficult on first glance, a rule of thumb will help you get there.

  • Wait for Mun-rise to finish from an approx. 100,000m orbit
  • Burn to raise your apoapsis to between 11.5 and 12.5 million.
  • Get captured by the Mun's gravity.

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!
