The thesis, drawn up in collaboration with the Italian aerospace company Argotec, discusses the feasibility study of a deep space weather mission through the use of a CubeSat platform.The first chapter consists of an introduction to the mission, presenting its main scientific and technological objectives. In the second chapter the discussion moves to a description of the activity of the system engineer, of the main tools used such as the Valispace software, fundamental in the design phase for the implementation of aspects such as requirements. The chapter concludes with a description of the trade-off methodology used within the project. The third chapter presents some aspects of the mission analysis investigated during the thesis process, such as the choice of the final orbit, the investigation of the available launch opportunities, the selection of a carrier and the best transfer strategy that can be adopted.
