The article provides a description of the activities aimed at the COSPAR planetary protection policy realization in the Phobos-Grunt mission. The results confirm that COSPAR requirements for Mars' protection against Earth-microbe contamination and Earth's protection against supposed hazards due to delivery of alien soil samples, are met. © 2012 Pleiades Publishing, Ltd.

This paper gives a concise overview of the robotic spacecraft that were the backbone of the priority position of the Soviet Union in space research in the 20th century. A brief description is given of the current and future spacecraft designed by NPO Lavochkin for fundamental studies of the Moon, planets, and small bodies of the Solar System, and for research in the field of astrophysics. © 2012 Pleiades Publishing, Ltd.

An estimate for the probability of a successful spacecraft landing în the complex relief of a celestial body given random initial landing conditions is considered. The estimation is performed according to values of these initial conditions, including landing orientation, the linear and angular velocity of the lander, as well as surface relief and behavior of the ground at the landing site. For a trial sample involving random landing situations, the equations of motion of the lander are solved, from which the discrimination rule is derived. Then a successful landing is predicted by means of the rule without the solution of the equations of motion during landing. © 2013 Pleiades Publishing, Inc.

In this paper, the problems of the application and development of models of space debris when designing means of the anti-meteorite spacecraft protection are considered. The developed method enables us to calculate the resistance of design elements based on the conjugation of a modified spatial model of the distribution of space-debris particles and ballistic limit dependences for a calculated element. © 2014 Pleiades Publishing, Ltd.
