The Moon Gravitational Field Chart Will Help to Study the Structure

NASA illustrative concept draws its gravity field according to the information in the two detectors from March to May this year over the moon after the probe, the strong gravitational field of red, blue indicates a weak gravitational field.

According to foreign media reports, NASA with the sisters run lunar detectors provide information to draw a precise lunar gravity field map in more detail will help researchers study the moon's internal structure and composition.

Aerospace house the found the thin the moon shell thickness than expected, between 35-40 km, and because of the influence of gravity, the surface layer of the lunar crust widely fragmentation may have more porosity, the density becomes homogenized, which 1970s last Apollo lunar mission obtained the data.

The researchers speculated that the lunar crust may be affected by the expansion in the early stages of the formation of the dykes cutting. rock crusher and circular vibrating screen

NASA pointed out that the new lunar gravity field map to reveal finer scale geological features of the moon, such as the internal structure of the extinct volcano terrain, Crater central peak.

The sisters detector "Ebner" (Ebb) and "Flo" (Flow) detectors formerly known as the Holy Grail A and the Holy Grail B (Gravity Recovery and Interior for Laboratory GRAIL), in January this year in a naming contest current name.

The two detectors in September last year, lifted off from Cape Canaveral Air Force Base. This two volume detectors, such as washing machines, flight altitude of 56 km away from the surface of the moon. Specializes in the detection of lunar gravity as the first project, a total investment of nearly $ 500,000,000.
