However, some aspects of its behavior are still poorly understood and remain the subject of very active research. “Two space missions have recently been launched to the Sun to resolve fundamental questions regarding its functioning and the impact of its magnetic activity on the heliosphere. One of these probes, Solar Orbiter, is the first operational mission of the program Cosmic vision of the European Space Agency, ESA Launched in February 2020, Solar Orbiter then made a 21-month journey of almost two billion km to return to Earth on November 27, 2021 and undergo assistance there. gravity, before starting the nominal phase of its mission with a first pass at a third of the Sun-Earth distance at the end of March 2022. In this conference, I will present the scientific objectives of this mission and its ten instruments”, says the speaker.
