Scientific paper

A simple calculation using the model of Melosh and Vickery (1989) shows that impacts may have contributed to the loss of up to 60 mbar of atmospheric surface pressure since the onset of the Martian geologic record. This is not enough to account for the loss of an atmosphere thick enough to form the geologic features, and additional loss mechanisms would be required.
