Abstract: The article explores the state and development of geodesic astronomy. The article compares the development of astronomy and geodesy. The distinction between astronomical and geodesic measurements is shown in the article. The main tasks of geodesic astronomy are described. The coordinate systems of geodesic astronomy are disclosed in the article. The article shows the similarity of the coordinates of geodetic astronomy with terrestrial coordinate systems. The article describes the features of the application of the results of astronomical definitions. The specificity of integration of space sciences and integration of space sciences is described. The article explores the nesting of spaces as the basis for the development of spatial sciences and geodesic astronomy.
Abstract: From the observation data, there is a significant discrepancy between the observed rotation curve of a disc galaxy and a curve derived from the theory. The theory of dark matter is currently postulated to account for the variance. Contrary to this assumption, authors present a theory by using tachyon field in the intetrgalactic space to explain the variance of the rotation curve of a disc galaxy.
Abstract: The article describes the evolution of the program of orbital research. The article analyzes the Salyut space program. The design features of orbital stations are described. The constructive development of orbital stations is described. The article reveals the content of scientific programs of space research. The fundamental and applied scientific research carried out using space technologies has been identified. The article describes in detail some of the application programs. The direction of the study of man in space was noted. The content of new sciences related to space exploration is revealed: space geodesy and space geoinformatics.
Abstract: The article explores the features and state of comparative planetology as a complex of scientific disciplines related to space exploration. The components of this scientific direction are shown. The integration aspect of discipline is shown. The main tasks solved by comparative planetology are revealed. The transformation of many earth sciences into the field of space research is noted. It is shown that the previous stages of comparative planetology focused on geology. At present, the geodetic and geometric factors play an important role in comparative planetology. The systematics of the orbits of the planets of the Solar system is performed within the framework of the comparative planetology approach. It is revealed that the orbit of the planet Earth is artificial in relation to other orbits.
