    Mass Moon
In summary, the moon has mass concentrations known as mascons, which were formed when the moon was young and had a liquid core. These mascons are made of dense rock and were created when large asteroids impacted the moon, causing craters to form and be filled by the molten rock. As the moon cooled, its core solidified and no new mascons can form.

I've come to understand that the moon has, beneath its surface, mass concentrations (masscons) that cause an orbiting craft to take a rather irregular orbit, and 'dip' when it passes over these areas.

Do we know what these masscons are comprised of?

If not, what are the most feasible predictions?

Mascons were created when the Moon was very young. In those days it still had a liquid core made of very dense rock. The surface was not as solid as it is now and much less dense. Whenever large asteroids and suchlike hit the moon they blasted away large craters of the less dense rock which were then filled by the molten dense rock rising up to fill the crater. Since then the Moon has cooled so the core is solid so no more mascons can form.
 

1. What is the concept of "Moon Mass Concentrations"?

Moon Mass Concentrations refer to the uneven distribution of mass across the surface of the Moon. This is due to variations in rock density and the effects of large impact events.

2. How are Moon Mass Concentrations measured?

Moon Mass Concentrations are measured using a variety of techniques including gravitational mapping, laser altimetry, and radar observations. These methods allow scientists to map the variations in mass across the lunar surface.

3. What causes the variations in mass on the Moon?

The variations in mass on the Moon are primarily caused by the different types of rocks and minerals that make up its surface. Some areas have denser materials such as iron and basalt, while others have lighter materials like anorthosite and breccia.

4. How do Moon Mass Concentrations affect lunar exploration?

Moon Mass Concentrations can have a significant impact on lunar exploration as they can affect the trajectory of spacecraft and the landing sites of missions. They can also provide valuable information about the Moon's geological history and the processes that have shaped its surface.

5. Are there any potential hazards associated with Moon Mass Concentrations?

There is a potential hazard for spacecraft landing on the Moon's surface in areas with high mass concentrations. The uneven distribution of mass could cause the spacecraft to crash or tip over. It is important for future missions to carefully consider and map out these areas before landing.
