The potential effect of the future Russian lunar laser ranging system (LLRS) on the accuracy of lunar ephemerides is discussed. In addition to the LLRS in Altai, several other observatories suitable for the LLRS installation are considered. The variation of accuracy of lunar ephemerides in the process of commissioning of new LLRS stations is estimated by mathematical modeling. It is demonstrated t...... hiện toàn bộ
The Spectrum of Torsional Oscillations of the MoonSolar System Research - Tập 34 - Trang 460-468 - 2000
T. V. Gudkova, V. N. Zharkov
The diagnostic potentialities of the torsional oscillations for probing the structure of the interiors of the Moon are investigated. Models with no core, a liquid core, and a solid core are considered. The profiles of compressional and shear wave velocities V

Structural disturbances of the lunar surface caused by spacecraftSolar System Research - Tập 46 - Trang 108-118 - 2012
V. G. Kaydash, Yu. G. Shkuratov
From the lunar surface survey performed with a narrow-angle camera of the Lunar Reconnaissance Orbiter (LRO) spacecraft, the distributions of the phase ratios of the Apollo 11 and 12 landing sites and the Ranger 9 impact site were mapped. In the acquired images, the traces of the structural disturbances of the lunar regolith layer caused by the jet flows are seen. In the Ranger 9 impact site, one ...... hiện toàn bộ

Abstract—The paper covers historical events related to the launch of the Luna-10 automated interplanetary station in 1966, which for the first time in the world became an artificial satellite of the Moon and performed a number of scientific studies and made discoveries in global astronautics.
Selection Effect in Semimajor Axes of Orbits of Extrasolar PlanetsSolar System Research - Tập 36 - Trang 466-477 - 2002
K. V. Kholshevnikov, E. D. Kuznetsov
We present a detailed analysis of the distribution of semimajor axes of orbits of extrasolar planets detected by the method of radial velocity measurements. The relation obtained enables one to calculate the probability of the discovery of a planet at a distance r from a star, knowing the masses of the star and the planet and the threshold radial velocity. The selection effect is manifested in the...... hiện toàn bộ
Optimization of the Return Trajectories from the Moon for Delivering Soil to a Specified Region on the Earth’s SurfaceSolar System Research - Tập 54 - Trang 654-661 - 2020
E. S. Gordienko, P. A. Khudorozhkov, A. V. Simonov
The construction of the trajectories for spacecraft return from the Moon to the Earth for delivering lunar soil to the polygon specified by the corresponding geographical coordinates (φΠλΠ) considered in this paper. A special technique for this purpose is developed. The spacecraft departs from the polar near-Moon orbit with a height of 100 km. The analysis of the energy characteristics of the spac...... hiện toàn bộ
