Editor's note: On September 10 last year, the sister probes "Eb" and "Flo" orbiting the moon were launched from Cape Canaveral Air Force Base in the United States. Researchers have analyzed the latest detection data and found that the thickness of the moon's solid shell, the moon shell, is about 35 to 40 kilometers. Researchers have also speculated that the moon crust may be cut by veins formed during its early expansion stage. Experts have drawn extremely accurate maps of the lunar gravity field. It is expected that three papers will be published in the American academic journal Science published on the 7th of this month to introduce the above results.
NASA announced on December 5 that with the help of information provided by sister probes orbiting the moon, "Eb" and "Flo", experts have drawn extremely accurate maps of the lunar gravity field, which will help Researchers study the internal structure and composition of the moon in more detail. It is expected that the American academic journal Science published on the 7th of this month will publish three papers to introduce the above results.
NASA pointed out that the new lunar gravity field map reveals the lunar geological features at a finer scale, such as internal structure, extinct volcanic terrain, and the peak of the central crater.
Researchers have analyzed the latest detection data and found that the thickness of the moon's solid shell, the moon shell, is about 35 to 40 kilometers. Under the influence of gravity, the upper part of the moon crust is widely fragmented, possibly with more pores, and its density becomes homogeneous, which is consistent with the data obtained from the last "Apollo" lunar exploration mission in the 1970s. Researchers have also speculated that the moon crust may be cut by veins formed during its early expansion stage.
The original names of the "Ebber" and "Flo" detectors were "Holy Grail" A and "Holy Grail" B, respectively. They obtained their current names in a naming competition in January this year. The two probes were launched from Cape Canaveral Air Force Base on September 10 last year. As the first exploration project dedicated to the study of lunar gravity, its total investment is nearly 500 million US dollars.
