AB: Atmospheric escape has been suggested as one important process on the following objects: 1. Extrasolar planets (hot Jupiters) 2. Early terrestrial-like planets (Earth, Venus, etc.) 3. Small solar system objects (Pluto, Enceladus, comets) Previous theoretical work and comparison with observationAL data will be summarized. New progress in the development of a multi-fluid hydrodynamic escape model will be reported. The importance and potential problems of in-depth studies of the atmospheric escape processes in Geosciences, Planetary Sciences, and Astronomy will be highlighted. A collaboration between geoscientists, planetary scientists, and astronomers will greatly improve our understanding on this complicated process and the evolutionary paths of the related objects.
