Atmospheric escape occurs at planets everywhere, and influences the evolution of planetary atmospheres and surface habitability. We argue for developing a common understanding of atmospheric escape that accounts for different star and planet characteristics. This requires comprehensive measurements at multiple planets, new models that cover the entire parameter space, and interdisciplinary effort.
