Introduction
Atmospheric Escape Plays A Major Role In The Climate
History And Evolution Of Mars. Quantitative Characterization Of The Current Atmospheric Loss Rate Is Thus Crucial To Understanding The Evolution Of Water And Co2
Inventories At Mars. During The Present Epoch, The Photochemical Escape Of Neutral Atoms Such As O, N, C And
H Is Understood To Be A Major Non-Thermal Escape Mechanism. One Of The Critical But Less Certain Parameter In
