The Moon is the only natural satellite of Earth. It does not have an atmosphere, making aerobraking impossible. However, it has a rocky terrain and a moderately sized radius and Hill Sphere. It has several craters like in real life.

The Moon is the closest body to Earth and has a low gravity (7 times lower than that of Earth in-game) and orbital velocity, making landing burns easy. It is also the place where players then go to after orbiting the Earth.

Many players choose to go to the Moon after orbiting the Earth, and usually before visiting the Red Planet (Mars).


Moon's surface

The terrain is covered with a lot of craters and a few mountain peaks. In between the craters the terrain is mostly flat with small craters on it. Some craters are inside a large crater, as seen above. Landing on an edge of a crater is safe, but there is a small risk of tipping over due to the Moon's gravity is so small. Landing on an edge of a mountain on the moon is safe, since the Moon's mountain peaks are not steep enough for rockets to tip over.

The safest zone to land on the moon is the areas between the craters. In that area, the terrain is mostly flat.

Moving on the Moon

Although the Moon has a low gravity at 1.42 m/s2, it is very high than Mars's moons, Phobos and Deimos, and a little bit low on the Galilean Moons of Jupiter. More RCS Thrusters are required to propel a rocket to liftoff. Considering the relatively low efficiency of the thrusters, 120s, moving on the surface with Rover Wheels or even using engines like the Kolibri Engine may be a more economic solution for moving.


  • Lunasynchronous orbit: 370.7 km
  • The moon in-game has less gravity than the real life moon.

Around the Moon

See also: Moon Activities

The Moon is the next destination for players to explore, after orbiting Earth. They first try to land on the moon, and then do complex things on the moon, such as Moon bases. Some even recreate famous space missions, such as the Apollo program.

They send different spacecraft on the moon, such as:


Impactors are spacecraft that are sent into a crash trajectory to the moon, then they crash on the surface of the moon. The remains of the spacecraft would bounce on the moon a couple of times, then it lands safely on the surface.

Lunar probes

See also: Space Probe

An orbiter or a satellite on the moon can be launched. Lunar flyby probes also passed on the moon, but they didn't land or orbit on the moon.

Some space probes used lunar gravity assists to help push the rocket out of the Earth's sphere of influence. However, it is unnecessary to do that in most landing missions, but in return missions, it is recommended to do that. One or two gravity assists can help push the rocket out of the earth and put it into a heliocentric orbit around the Sun.


Landers are spacecraft that land on the moon. Players usually do that before even going to do complex activities.

Moon rovers

Moon rovers are vehicles that drive on the moon. They explore the surface of the moon.

Rovers may get upside down when going into rough terrain (such as craters or mountains). So, it is advised to drive slowly.

Lunar space station

A lunar space station can be built on the Moon. They usually sit in a medium orbit. They refuel spacecraft to land on the moon, and to return to Earth orbit and return safely. They can have their own lander, and return to the space station.

A lunar space station can be used to dock service modules and capsules while the other astronauts explore on the moon lander that has landed. They wait until the lander docks to the space station again. They then return to Earth.

Lunar base

Lunar bases and launch pads can be built on the moon, if they are near a crater on the moon. The launch pad can be in the moon's craters or near the base, and can launch multiple rockets to send it to somewhere else.

Buildings may be built beside the launch pad.


Moon orbiting Earth with its Hill sphere and orbit visible


  • The Moon has areas with red, blue or yellow on it.
  • The Moon's gravity was reduced from 1.62 to 1.42 in version 1.4.
  • The first unmanned moon landing was on 13 September, 1959, at 21:02:24 UTC.
  • The first manned moon landing was on July 16, 1969, at 20:17 UTC.
  • At present, the Moon gets 3.8 cm further away from Earth every year.
  • In about 50 billion years, the Moon will stop moving away from us and settle into a nice, stable orbit. At this point, The Moon will take about 47 days to go around the Earth. Currently, it takes a little over 27 days. (Source Here)
  • Then he escapes earth's SOI because the sun's gravity takes him outside.
  • The Moon formed by a Mars-sized planet crashing to Earth called Theia. The debris then coalesced to form the Moon.
  • After its formation, The Moon even had an atmosphere, 0.012 bar to be exact.
  • The moon will escape Earth's gravity 2.1 billion years from now.
  • The moon actually has a very thin atmosphere in real life, composed of water vapor emitted from humid lunar dust as of the discoveries of the Chang'e missions, the Chandrayaan 1 mission, and NASA's LRO and LCROSS.
  • The moon might have lava oceans once.
  • The moon has practically no atmosphere so parachutes and aerobraking will not work.
  • The moon is now explored by many spacecraft, including the Apollo spacecraft, which landed on the moon and returned back to the Earth safely.
  • Some players even try to go to the moon, go back to Earth, go to the moon again, and return to Earth again. This thing is very complex, since they need a large rocket, or dock extra stages to the main rocket itself, or using a helping rocket to refuel andor send it into the moon in the second attempt.
