Objective: Development of new methods for remote identification of artificial and natural disturbances of regolith layer during the NASA space mission Lunar Reconnaissance Orbiter (LRO). Obtaining new data on the structure, optical and physical properties of the lunar surface using high-resolution data. Research methods and instruments: For treatment of the available photometric data (primary cosmic and telescopic images) authors of the project created algorithms and programs that were previously tested by comparing the calculation results with the known cases. The authors have created interpretive framework for analyzing lunar photometric data with the help of theoretical modeling. In particular, the project authors developed theoretical models of light scattering by rough regolith-like surfaces. Project Results: Using the method of phase and time ratios we study the new craters of natural origin on the lunar surface; identified and dark halo craters of the ray system, characterized by significant slope of phase function. The authors have provided a new explanation of effect that can lead to the appearance of dark halo and rays around the new just created lunar craters. The authors have provided photometric interpretation of anomalies that are associated with the action of gas jets of landing module spacecraft on the lunar surface. It is shown that the method of phase ratios can be successfully applied not only for the study of landing sites, but for the slopes of young lunar craters where the regolith transport processes can be greatly developed. New method of remote sensing proved photometric detection of anomalies associated with known influence of human activities on the lunar regolith. Novelty, effectiveness of implementation: The authors of the project proposed and implemented in photometry new tool for space remote sensing of planets - method of phase ratios, which enables remote assessment of density and roughness of the lunar surface. The formation of new craters and seismic / tectonic events may lead to changes in the structure of the surface. This effect, in turn, leads to changes in the regolith photometric properties that enables remote identification and search of new areas of formation of craters, small comets or falling meteoroid swarms on the lunar surface. The practical value of the project is that the new maps photometric parameters created during the project can be used in the planning and implementation of space missions to the Moon and other atmosphereless Solar system bodies by space agencies in geological and astrophysical research for the study of the earth's resources; in optics and light scattering of regolith-like particles and surfaces. The results can be used in the development of scientific instruments for research of the lunar surface, and the Earth; These devices are created by the Concept of state policy in the field of space activities for the period until 2032. The new results could be used in carrying out tasks on lunar space research planned in the national scientific and technical space program for 2013-2017 years.
