Water on Mars
Mars Orbiters
Thermal Emission Spectometer
Topography Suggesting Water At Surface
Debris Covered Glaciers
Snow Deposits
Dried Streams and Gullies Leading Away From Frozen Water Source
Ice Near Volcanos
Martian Clays
Older, Cratered Areas
Crustal Clays
High Fe/Mg
Closed, low W/R systems
Ancient Clays Forming Underground Due To Hydrothermal Subsurface Circulation
Some Water Present, But No Exposure To Surface Water
Newer, Less Cratered Areas
Sedimentary Clays
High Sulphate and Chloride Salts
Open, Low W/R
Formed Due To Evaporating Surface Water
Surface Water Present, But Very Little, And Water On IT's Way Out
Clays in Stratigraphy
Al Clays
Open, High W/R
Formed In The Presence Of Significant Surface Water
Surface And Ground Water On Mars Was Present On Mars When Crustal Clays Deposited, Spiked When Clays In Stratigraphy Formed, And Dropped Of When Sedimentary Clays Were Deposited
Water Levels On Mars's Surface and In Ground Water Very Greatly Over TIme and Location
Spirit Rover
Gusev Crater
Possible Ancient Lake Bed
Olivine and Pyroxine
Liquid Water Not Present For At Least 3 Billion Years
Columbia Hills
Sulphur Salts
Possibly Deposited By Liquid Water Or Sulphiric Acid
Olivine And Pyroxine
Opportunity Rover
Plains Of Meridiani
Crystalline Hematite
Possibly forming due to liquid water
Plains Of Meridiani Once Underwater
30-40 Percent Sulphate
