The term ‘atmospheric escape’ refers to a suite of processes, each of which is capable of removing particles from a planet’s atmosphere. These processes involve different physics and each can be important (or unimportant) in different contexts – processes include thermal escape, hydrodynamic escape, ion escape, photochemical escape, sputtering, and impacts. Atmospheric escape is observed to occur at many solar system planets as well as at exoplanets. Based on both observations and models, we infer that escape can have a large influence a planet’s evolution and (in the case of rocky planets) habitability. We welcome contributions about atmospheric escape and its consequences from modelers, theoreticians, and observers studying Earth, solar system planets and moons, and exoplanets.
