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.

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.

The "Spektr-UF" project is intended for the design and development of a large space observatory operating in the ultraviolet (UV) band of the spectrum inaccessible for survey from the surface of the Earth. The main observatory instrument is a space telescope T-170M with a primary mirror 1.7 m in diameter; it will be equipped with high and low resolution spectrographs and cameras for high-quality UV imaging. In respect of capabilities, the project is similar to the American Hubble Space Telescope (HST), and exceeds the latter in some parameters. The project is included in the Russian Federal Space Program for the period 2006-2015. The launch is planned for 2016. The project is under development by the Lavochkin Association in cooperation with the Institute of Astronomy, Russian Academy of Sciences. © 2013 Pleiades Publishing, Inc.

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.

A mathematical model of a space synthetic aperture radar (SAR) has been developed. It is used to analyze the impact of errors in determining the position in space and the spacecraft velocity on the geolocation of obtained radar images (RI). © 2014, Pleiades Publishing, Inc.

The control of the orbital structure of the satellite constellation (SC) of continuous service with spacecraft in highly elliptical orbits of the Molniya type is considered. For ensuring the SC dynamic stability, it is proposed to use passive, active, and combined approaches to the SC orbital structure control. A statement of the problem to ensur e dynamic stability is given and results of its solution for a particular variant of the orbital construction of the Arktika-M space system are presented for the passive control approach. The proposed orbital structure control is based on minimizing the evolution-induced space-time deformation of the orbital structure by means of differentiated selection of initial parameters of orbits at the stages of the SC deployment and replenishment and by means of control of the spacecraft’s ground track at the SC operation stage. Using this control method is especially important with long active life spans of spacecraft and limitations on propellant margins for orbit correction. © 2014, Pleiades Publishing, Inc.

The problem of how to determine parameters of motion for an automated interplanetary probe (AIP) on a quasi-satellite orbit during flight to the small natural satellite of a planet is examined. The problem is solved by searching for an optimal state-space trajectory of automated interplanetary probe according to the least-squares criterion. The results of longitude and latitude measurements at several points are used as boundary conditions. © 2014, 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.

We consider the problem of ensuring an energy balance of geostationary spacecraft (SCs) that will arise on October 13, 2015, during the long-duration eclipse of the solar disk visible from the SC by the Moon and the Earth. A technique for assessment of the eclipse duration, taking into account the shaded area of visible solar disk, is set forth, and results of calculating the eclipse conditions for different SC “stationary” points in the geostationary orbit are given. The data presented will allow the specialists to be prepared in advance for specific ballistic conditions of SC operation at this date and to plan operations to ensure the power balance of the SC power supply system during the prolonged shading of the Sun by the Moon and the Earth. © 2014, Pleiades Publishing, Inc.
