ESA's future Vigil mission (formerly, Lagrange mission) will keep constant watch on our Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure.
ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.
