Lire la suite >The collisionless plasma of the Earth’s magnetotail hosts non stationary plasma transport caused by fast and transient flows moving towards the Earth with speeds larger than hundreds of km/s. These flows generate sharp increases of the northward component of the magnetic field called dipolarisation fronts. These kinetic scale structures of a few ion inertial lengths along the direction of propagation are associated with an intense wave activity such as lower-hybrid waves, whistler mode waves and electromagnetic phase-space holes. Furthermore, these dipolarisation fronts move with their own dynamic current circuit and drive important energy conversion processes contributing to the energy global cycle of the magnetospheric system. I propose to discuss recent results obtained by analysing data from the Multiscale Magnetospheric mission consisting of four satellites evolving in a tetrahedral configurationand separated at the electron scale. Finally, I will stress the need to go further by implementing new space missions capable of measuring the kinetic and fluid scales simultaneously.Lire moins >
