A new image of the gravity of the moon on Earth contains a record of billions of years of the effects on the surface. The new map, created by NASA gravity recovery and Interior (Grail) laboratory mission, is now the highest resolution of the gravity of a celestial body connection field. This will enable the researchers to learn about the internal structure of the Moon, tectonic structures, volcanic landmasses, pelvic rings peaks of Central crater and craters.

"What this tells us is that more cards than any other celestial body we know, Luna lead the gravity field in your pocket,"said Maria Zuber, Principal investigator of the Grail in the Massachusetts Institute of Technology (MIT)"."If you see a remarkable change in the gravitational field, we can synchronize this change with the topography of surfaces, features such as craters, rhymes or mountains."

The gravity map is created from data that washer two SMB space (Graal-A and B, or Ebb of the Grail "and" Flow "") orbit around the moon. Precision radio signal measures the distance between them while the probes orbiting the moon. Going through areas more or less strict on the Moon, the distance between them to change anything.

The probes also showed that the density of "significantly" lower than expected Lunar Highland crust. However, the density is compatible with data from the Apollo missions in the 1970s. This suggests that the samples given by astronauts on the Moon is a good representation of processes on the moon. The composition of the Moon's mass is also similar to the Earth, to provide documentation of patterns, proving that the Moon was formed by a large impact with Earth in the solar system early.

"Use gradients in the gravity field, small and narrow which may verse structures of set of data prior to the stress," says Jeff Andrews-Hanna, scientific Grail at the École des Mines of Colorado. "These figures show a population of anomalies of the gravity lengthwise, linear, with a distance of hundreds of kilometers, crossing the area. This linear gravity anomalies indicate the presence of dams or long and slender, vertical bodies of magma underground. Dykes is one of the most ancient features on the Moon and she understands, it will tell the story.
