Exploring for Martian Life

Abstract

During the next decade, robotic field science will play an essential role in advancing our understanding of Martian history. Specifically, capable rovers are needed to survey a broad range of Martian rock types for in situ chemistry and mineralogy as a basis for interpreting globally-distributed data obtained from orbit. The relationship between orbital and landed science will be fundamental in selecting a landing site for future missions aimed at probing the ancient rock record for evidence of: (1) past life or prebiotic chemistry; (2) the climate and volatile history of Mars; and (3) candidate materials for in situ resource utilization.
