The applied goal of the project is to study the formation and dynamics of aerosol of space origin and the impact of micro-meteoroids on the Earth's atmosphere and the safety of spacecraft (SCs). The main idea of ​​the project is to use existing and new quasi-simultaneous spectral, photometric and polarimetric observations to study non-stationary processes and spatial and temporal variations of dust and gas characteristics in the atmospheres of active MTSS of different dynamic classes. The objectives of the project are: to obtain new knowledge about non-stationary processes in active small bodies and the mechanisms of activity that cause them; to determine the macro- and microphysical properties of the material ejected during activity, which is closest in chemical composition to the primary substance of the protoplanetary nebula; determination of physical, optical and chemical characteristics of dust and study of its evolution in the atmospheres of active objects; improvement of the geometric model of jets and, based on it, study of morphological structures in cometary insects and their connection with active regions in the nucleus; analysis of the relationship between spatial distributions of intensity, color and polarization in cometary insects of different families; study of the impact of cosmic dust particles on near-Earth space and the Earth's upper atmosphere.  Product Description popup.authors Ivanova Oleksandra V.
