Aerospace engineering concerns the development of technologies for atmosphere and space. The design of vehicles, launch systems and payloads cannot thus disregard a deep understanding of such operational environments. The main purpose of this class is to provide a detailed description of the physics of the interplanetary space and of the outermost layers of the Earth’s atmosphere, as well as to describe the coupling between solar activity and Earth’s dynamics. The interplanetary medium and the upper atmosphere are in the plasma state and they both develop a strong turbulent character. Theory and modeling of space plasmas and anisotropic turbulence will be proposed here, technologies and tools to investigate these environments will also be introduced.
