The systemic approach in astronautics Everyone who has linked his life with astronautics and those who are interested in the future of the inhabitancy medium and its expansion up to cosmic scales, are troubled about the current state and development of space activity in the World and in the Native Land of the first artificial Earth satellite (AES). ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

... Тhis new concept touches our simple lives, yet for those intrigued by the natural sciences, especially experts deeply engaged in the 'eternal' questions of general geology and astronomy, it is all the more fascinating. The problems to be faced by any theory for the formation of the Solar System . Any theory has to account for certain rather tricky facts about the Solar System. These are in addition to the obvious facts that the Sun is at the centre with the planets in orbit around it. ...
