Loss rates depend on highly variable plasma conditions

The cold plasma electron population is the mainly responsible for H₂O and H₂ loss

Maximum loss is expected under median and median or high plasma conditions for H₂O and H₂ respectively

O₂–O₂⁺ charge-exchange process may have a dominant role in the exosphere loss

O₂–O₂⁺ charge transfer rate is in the range (13–51)×10²⁶ s⁻¹
