Currently, the southern polar region of the Moon is considered as the priority landing area for the planned lunar mission Luna-25 (Moon-Globe). Nevertheless, in this paper we have examined some areas in the North Pole region of the Moon as possible landing sites for future lunar missions. For a research we have chosen some areas located in the northern polar region: area of a crater Peary (88,9?N, 32?E), area in vicinity of Rozhdestvenskiy U crater (84,9 В° N, 152 В° E) and a Nansen F crater (84,95 В° N, 62,44 В° ...

Space weather can be monitored from the ground (astronomic/astrophysics observations and geomagnetic observatories) and from space (satellite data). Optical instruments (telescopes on the ground) recording the number of sun spots, as well as to viewing aurora, but these observations are affected by the weather from Earth's atmosphere. Observation from space does not have such a limitation. In the last years,satellites and spacecraft have monitoring the space weather. Through cooperationbetween European Space Agenc...

The present paper focuses on describing the method of bringing dynamic space images of various celestial objects to the uniform reference system. This approach is designed to analyze coordinate and time parameters of cosmic bodies in various phase spaces.Based on this method, images of the Moon and stellar areas obtained with CCDmatrixes were studied. As a result, reducing the images to the single system achieved the accuracy between 0.05 and 0.11 arc seconds by declination and between 0.04 and 0.13 arc seconds by...

The present paper shows that the analysis of full flow X-ray activity signals recorded by the ASM (All-Sky Monitor) survey camera of RXTE (Rossi X-ray Timing Explorer) orbital observatory for binary systems allows for not only establishment of some mechanisms of matter accretion in binary star systems but classification depending on manifestation of statistical memory effects as well. As an example, using frequency dependencies of autocorrelators and their derivatives calculated on the basis of Memory Function For...

This article discusses the possibilities of using a 3D printer with parallel kinematics that can produce good quality prototype components such as various covers, handles and functional assembly for simple electronic devices or robots. It will enable combining the printer with an engraving CNC machine, so that the effector head of the 3D printer will allow the head to be exchanged for printing with an engraver head, and it will allow fine engraving on printed circuit boards. The printer effector is equipped with a...

In the present work for the first time in the world practice 430322 occultations of stars by the Moon are analyzed. The relevance of the work is that the accuracy analysis of stars' proper motion in modern star catalogues can only be conducted using either observations of small planets or occultations, since only those observations are longterm and homogenous in time. When making the occultation database a comparative analysis has been used to study types and accuracy of occultation. For photoelectric observations...

Long-duration human space flights involved by interplanetary journeys or space station missions expose the crews to effects of weightlessness. Such effects, consisting in loss of bone density, skeletal muscle atrophy, cardiovascular deconditioning etc., can raise significant risks on the health of the astronauts and for their capacity to accomplish the missions. Therefore, a large number of studies were dedicated to solutions for creating artificial gravity. The paper studies dynamic effects produced in a tethered...

It is known that the movement of the liquid core creates electric currents, inducing a main magnetic field of the planet. The liquid core of the high temperature becomes ionized plasma (plasma), which It is quasi-neutral (not neutral) - by definition. One of the major geodynamo questions: what is the source of strength, causing fluid movement in the core of the planet? Many authors have investigated geodynamo: planetary rotation around its axis, the temperature difference and pressure as well as the Coriolis force...

During summer field trips were collected several cores from Lake Rubskoe. Cores length is about 6 m and maximum age approximately 13 Ka according radiocarbon dating. For investigation chosen core ?4 (56.72545пїЅ N, 40.60657пїЅ E), were sediment sequence not destructed. Core was divided into 2 cm samples. Thermomagnetic curves measured for every fifth sample. The rate of heating was 100пїЅC/min. The measurements made in a constant magnetic field пїЅ 200 and 400 mT. We have got thermomagnetic curves of the first and...

The results of the electron temperature distribution modelling in the F region of the subauroral ionosphere for different helio-geomagnetic conditions are presented taking into account magnetospheric heat fluxes. The study has been carried out using the threedimensional model of the high-latitude ionosphere in EulerпїЅs variables which taking into account its thermal regime. It is shown that during the period of low solar activity in winter solstice condition the displacement of poles leads to regular longitudinal...

This article deals with the modification of the nozzle and its entire assembly with a hot end, so that it was not necessary to use a tephlon insertion and it was possible to reach the maximum temperatures of the nozzle reaching 280пїЅC and above. With the gradual development of 3D printing technology FDM (fused deposition modeling), i.e. the fritting of the thermoplastic in the shape of the fibres and putting it into the layers, more demands are placed on the materials used. Materials with a greater temperature of...

Numerous space agencies and powers have announced their plans on lunar exploration for the next years. The main purposes are preparation and creation of long-term scientific, technological, experimental, and industrial bases on the near side of the Moon and in the areas of the lunar poles for conducting scientific experiments and investigating lunar bowels. The American space agency (NASA) has published the most detailed for today map of the lunar South Pole. The new data has been collected by the пїЅLunar Reconna...

Mathematical models of the dynamics of spacecraft with a solar sail to control translational orbital motion and rotation of the whole structure are provided the stability of the sail orientation relative to the flow of sunlight. The behavior of solutions in a neighborhood of the possible equilibrium or stationary state of motion is taken into account. Change in the stability depending on the tasks and the transformation of equations that describe the perturbed processes is taken into account. It is possible to var...

The technological progress did assure in the past the desire of the humanity to increase the quality of life. The developments did however emphasize that beside wanted effects of technological progress, undesired effects can appear. In order to find solutions for this dilemma, global debates on scientific and political levels started some time ago. In the Brundtland Report 1987 the concept of sustainable development has been defined and accepted as a possible solution for the global complex problems. When consider...

The aim of this article is to study astronomical refraction anomalies. Back in 1925 Grachev and Banahevich found systematic errors in meridian observations depending on zenithal distance. Grachev suggested that these refraction anomalies arise from the inclination of the Earth's surface to the South. The airstratas of the same density were considered as parallel to the Earth's surface. But the analysis of latitude observations from the Bamberg and ZTL-180 telescopes showed there were significant systematic errors ...

The purpose of the present study is to apply the new methods of multi-parametric analysis to moonquakes. It should be noted such physical phenomena as moonquakes are some kinds of complex systems. As the works in which analysis of moonquakes observations is conducted have shown, lunar seismophysics is much more complex process than Earth's geophysics. This is why to study the physical nature of moonquakes and their parameters it is necessary to use methods of statistical physics and robust estimates. Currently, th...

The present work is focusing on construction and analysis of 5 lunar models using space and ground observations. Firstly, it should be noted that the task of building a model of the lunar macro-figure relative to its center of mass and axes of inertia does not have a definitive solution yet. Within the present work the models of the lunar macro-figure are developed on the basis of space and ground observations. The methods of observation had implied binding of lunar objects to stars, i.e. celestial coordinate syst...
