LPP is taking part in the Solar Orbiter mission, which was launched from Florida on the night of 9 to 10 February. Objectives: to explore the solar wind and understand the activity of our Star through in situ measurements and new telescope observations. The European Space Agency’s Solar Orbiter mission took off during the night of 9 to 10 February from Cape Canaveral, carried away by an Atlas V rocket supplied by NASA. Thanks to the gravitational assistance of Venus and Earth, the probe will approach less than one third of the Earth-Sun distance and observe for the first time the poles of the day’s star as it exits the ecliptic plane. At the same time, the properties of the solar wind around the probe will be analysed by measuring instruments to which the LPP has largely contributed. The aim of the mission is to understand the origin and dynamics of the solar wind that fills the interplanetary space and to elucidate the mechanisms of generating the solar magnetic field. It reconfigures abruptly during solar flares that can send energy particles, ionizing radiation, and magnetized plasma clouds throughout the heliosphere. These events severely affect our environment: they can damage satellites in Earth’s orbit and affect our communication and positioning capabilities. The mission will provide a better understanding of the origin and propagation of these major space disturbances in the ...
