The electromagnetic coupling between the seismically activated area and the ionosphere is considered within the framework of the Global Electric Circuit (GEC) conception. First we consider the anomalous variations in the ionosphere associated with the earthquake preparation process, their temporal and spatial characteristics using the results from recent publications. Then the GEC conception is presented shortly with main accent put on ionization processes which play key role in the complex chain of physical and chemical interactions changing the electric properties of the planetary boundary layer of atmosphere. We treat this part of troposphere as an open complex system with dissipation where so called "blow up" processes are developed leading to sharp and fast changes of atmospheric parameters including the electric properties of the boundary layer. The new concept named Spatial Scintillation Index is introduced in the last part of the paper. In general, this paper may be considered as a short review of the recent achievements in understanding of the seismo-ionospheric coupling. © 2014 COSPAR. Published by Elsevier Ltd.

The Node Module (NM) will be a new element of Russian Segment (RS) of the International Space Station (ISS). It is targeted for launch in 2014. This spherical-shaped module (D 3.3 m) is equipped with six docking ports and will be attached to the nadir port of Multipurpose Laboratory Module (MLM), providing its five free ports for other modules and transportation vehicles docking to the ISS. NM will be also equipped with a Thermal Control System (TCS) of new generation that should support its functioning within 30-year lifetime period. The TCS should provide nominal (in accordance with specifications) temperature conditions for NM structure, for onboard systems functioning, and to maintain a temperature range of inner gas environment. Due to some structure features of NM and low level of heat dissip+ation from the equipment installed, it is possible to consider a TCS of passive type with heat pipes. This paper analyses some results of TCS simulation, provides a comparison between suggested TCS and a traditional system, and also shows advantages of a selected method for NM structure thermal conditioning. In the paper a new in essence thermal conditioning method of manned spacecraft structure is described. This lightweight TCS is to be highly reliable with low level of power consumption.

For linear stationary models of the spacecraft motion, a modification of the exact pole placement method is developed that makes it possible to design a modal control for any class of linear stationary systems. In the case of circular orbits, the modified method is used to obtain an analytical solution of the problem of gravitational angular momentum unload problem for inertial actuators of a spacecraft in the gyroscopically coupled roll-yaw channels. © 2013 Pleiades Publishing, Ltd.

There was only one spaceflight participant in each crew of the Soyuz spacecraft commercial missions. Existing spacecraft design capabilities, as well as spacecraft operation requirements, do not allow expanding the number of spaceflight participants. After putting the commercial manned spacecraft Crew Dragon and Starliner (CST-100) into continuous operation it could be possible to add two or more spaceflight participants to the crew, which will expand this segment of the market and possibly lower price per seat. Increase in supply on the commercial manned spaceflights after Advanced Crew Vehicle, Dream Chaser, and, perhaps, Shenzhou spacecraft market entry will boost work on commercial orbital stations. Currently there are a lot of space technology experiments and researches carried out in low Earth orbit. If the needs for new materials and drugs obtained by the space production are determined within 10 years, the conditions for the commercialization of manned missions in low Earth orbit will be created along with commercial spaceflights. The commercial manned spaceflights market size can be up to $1 billion by 2025.

Space experiments associated with technology development and demonstrations aboard the Russian segment of the International Space Station (ISS RS), for the benefit of the future space missions, can be considered as one of the most important parts of the ISS RS utilization program. New-generation onboard laser communication systems; new systems for damage detection and repair work in outer space during crewmembers' extravehicular activity; the launching in orbit of micro-, nano-, and picosatellites, both from the station and from a cargo spacecraft during its autonomous flight; and new environmental control systems both inside and outside the station - all of these make valuable contributions to future space exploration, and also serve in many respects for the benefit of humanity. This paper explores the major results of Russian experiments on space technology development and demonstrations aboard the ISS RS, and analyzes their future applications.

With the use of a mathematical model developed for describing hysteresis functions of aerodynamic forces and moments depending both on the angle of attack and on the rate of its variation, the emergence of a hysteresis in flight tests of the Soyuz reentry capsule at the hypersonic segment of its descent is found to be induced by damping. © 2011 Pleiades Publishing, Ltd.

Mission Planning is one of key components of orbital stations control, and the International Space Station (ISS) is one of them. The efficiency of Flight Program execution as well as the accomplishment of mission objectives depends to a large extent on the quality of Flight Plans. Upcoming addition of new modules to the ISS Russian Segment (RS) and crew expansion to six people made it necessary to evaluate the readiness of planning tools for new ISS configuration. Working on the subject the author did expert analysis of the existing automated Planning system. Analyzed was RS flight operations planning process at the executive level, taken into account were the amount of planning data being processed, modern techniques and approaches used in automated processes. As a result it was considered urgent to develop new automated planning tools. The new Planning system provides continuous planning cycle at the executive level. It is built as a modular system and at the same time it is based on common structure data, which enables the system to be upgraded and to interface with ISS International Partners and RSC-Energia departments.

Instrumental errors of measurement wide-aperture laser beam diameter were modeled to build measurement setup and justify its metrological characteristics. Modeled setup is based on CCD camera and transmission diffuser. This method is appropriate for precision measurement of large laser beam width from 10 mm up to 1000 mm. It is impossible to measure such beams with other methods based on slit, pinhole, knife edge or direct CCD camera measurement. The method is suitable for continuous and pulsed laser irradiation. However, transmission diffuser method has poor metrological justification required in field of wide aperture beam forming system verification. Considering the fact of non-availability of a standard of wide-aperture flat top beam modelling is preferred way to provide basic reference points for development measurement system. Modelling was conducted in MathCAD. Super-Lorentz distribution with shape parameter 6-12 was used as a model of the beam. Using theoretical evaluations there was found that the key parameters influencing on error are: relative beam size, spatial non-uniformity of the diffuser, lens distortion, physical vignetting, CCD spatial resolution and, effective camera ADC resolution. Errors were modeled for 90% of power beam diameter criteria. 12-order Super-Lorentz distribution was primary model, because it precisely meets experimental distribution at the output of test beam forming system, although other orders were also used. The analytic expressions were obtained analyzing the modelling results for each influencing data. Attainability of <1% error based on choice of parameters of expression was shown. The choice was based on parameters of commercially available components of the setup. The method can provide up to 0.1% error in case of using calibration procedures and multiple measurements. © 2015 Copyright SPIE.
