The space technological applications of the celestial mechanical Lagrange points in the protection of environment

Space-technology can in the future help to solve two burning global problems of mankind: global warming and the storage of radioactive waste. In the space technological solution of these problems the celestial mechanical Lagrange points of the Sun-Earth and Earth-Moon systems can play an important role. Therefore the celestial mechanical theory and computer simulation of the nature of Lagrange points have great importance in some aspects of the protection of the environment, too. The two examples given, propose: storage of radioactive wastes in the stable Lagrange points L4 and L5 reduction of the global warming by positioning satellites with large mirrors in the collinear Lagrange point L2 thus shadowing the incoming solar radiation.
