AGN outflows impact the evolution of supermassive black holes, host galaxies, surrounding IGM, and cooling flows. However, the physical properties of these winds are poorly known. We propose to obtain the deepest RGS spectrum of any AGN, allowing us to determine the physical conditions of the gas. Through monitoring of the warm absorber using the combined EPIC and RGS spectra we will unambiguously constrain the location and geometry of this outflow. These unprecedented constraints allow us to estimate the parameters that determine the effect of AGN outflows on their environment: mass flux and kinetic luminosity. For this ambitious program, we propose to observe Mrk 509 for 600 ks using 10 observations of 60 ks each, spaced by 4 days.
