Water on Mars We can calculate a water budget of Mars….. total H2O in present polar ice caps + total H20 in atmosphere + total H20 lost to space Accounts for only 10% emitted by degassing About 90% of Martian water is stored as underground ice Current orbit Eccentricity = 0.093 Orbital extremes: 1.65 AU to 1.38 AU

Unformatted text preview: Axial tilt = 25.2 degrees Past orbits Axial tilt can vary between 15-40 degrees, perhaps as much as 0.2-51.5 degrees Eccentricity can vary between 0 and 0.13 This could cause major changes in atmospheric pressure….perhaps pushing pressures up to 3-4 times current levels...
