Magnetic reconnection is a key process in space, astrophysical, and laboratory plasmas that explosively converts magnetic energy into kinetic energy of charged particles. Thanks to recent spacecraft missions (e.g., MMS, Cluster, THEMIS, MAVEN, Parker Solar Probe, Solar Orbiter, etc.) and the development of numerical simulations, many new findings have been achieved in the last several years. However, many important issues remain, e.g., the triggering and cessation mechanisms, quantitative aspects of the energy conversions, identification of the electron diffusion/dissipation region, charged particle energization, the coupling between micro-scale and global-scale physical processes, and so on. This session invites presentations on all aspects of magnetic reconnection from spacecraft measurements, theoretical analysis, numerical simulations, and laboratory experiments.
