... . Taking lessons suggested for Martian desert, polar and mountain expeditions, I describe this expedition using a 120??W, 300??W longitudinal route. I quantify the in-situ resource utilization (ISRU) requirements ... inventory of samples gathered across the Martian surface. The planning of such an expedition provides a reference expedition for considering ISRU and scientific requirements for any long- duration, long-distance scientific ...
