The images obtained allowed to distinguish the details of the size of a little bit millimeters. At the same time on the lunar surface was not detected previously thought by some scholars of the dust layer deep in depth. It turned out that the Moon's surface is rough and has the possibility of small pits or tubercles. There are rocks the size of 15-20 cm and more. Studying the structure of the lunar surface was extended station 'Luna-13', which made a soft landing in December 1966 This station is on a special apparatus (gruntomer, dynamograph and a radiation densitometer) for the first time made a direct determination of physical and mechanical properties of lunar soil, which showed how much the Moon's surface lies a layer of granular material with densities of 0.8 g/cm3 equal thickness of only 5 cm Similar studies were carried out up close and American vehicles 'Surveyor'. Great scientific minds for lunar exploration is the work of artificial satellites of the Moon. The world's first artificial lunar satellite has automatic station "Luna-10 ', launched March 31, 1966 followed by its satellite to orbit the moon came the Soviet automatic station" Luna-11', 'Luna-12' is the American type 'Lunar Orbiter. " Flights are not satellites of the Moon only given the important news of the physics of near-moon space, but allowed for gamma-ray spectrum of the Moon to the conclusion about the nature of the minerals comprising its form, and to conclude how many rocks of the lunar soil are close to basalt.
