Trapped Ar isotopes in meteorite ALH 84001 indicate Mars did not have a thick ancient atmosphere
Water is not currently stable in liquid form on the martian surface due to the present mean atmospheric pressure of ∼7 mbar and mean global temperature of ∼220 K. However, geomorphic features and hydrated mineral assemblages suggest that Mars’ climate was once warmer and liquid water flowed on the s...
