Introduction: Identification And Mapping Of The Surface And Underground Water Environment On Present Mars Are Important To Investigate The Existence Of Life And Reserve Water Resources For Future Manned Missions. Especially, The Recurring Slope Lineae (Rsl), Dark Streaks Which Appear On Steep Slopes Such As The Edge Of Craters In Specific Seasons [1], Have Been Noticed As Important Targets As Possible Water
