Scientific paper
Data on C, N, and O inclusions on Mars are examined in order to investigate the historical atmosphere of the planet. The results indicate a ratio of N-15:N-14 escape rates of 0.53-0.62, suggesting a lower than 1 mb initial complement of nitrogen. Alternately, the low enrichment of N-15 observed by Viking may result from continuous outgassing from the surface together with the current loss processes, a scenario which is consistent with an initial complement of N2 lost via physical or chemical processes early in the planet's evolution. It is suggested that abundant kilometer-deep H2O has persisted up to the present epoch, and that the Martian atmosphere as occluded in SNC meteorites during the last 1.3 Ga would be a little lighter isotopically in C and O, but potentially heavier in N, than the current atmosphere.
