The Particles Releasing Process Using Injections for the Exploration of Active Space Experiment

The techniques of Active Space Experiments (ASE) include the particles injection and electromagnetic beams emission into geospace from ground or space. Based on the mechanism of the interaction between dusty particles and plasmas in ionosphere, this paper analyses the effect of particle shape on the charge effects of plasma. The processes of superfine particles injection and particle clouds formation are also discussed. This paper presents some results from theoretical analysis, experimental results and numerical simulations. The results show that the well-organized local space structure of nanoscale slender particles cloud display scattering effect to electromagnetic waves along with stronger electron adsorption capacity. The results also show that the nanoscale particles behave the shorter relaxation time than the microscale particles and in mesosphere a particles cloud of 800 meter scale can be produced using the injections method.
