Speculations on the igneous history of Mars: Inferences from the SNC meteorites

摘要

In general, attempts to delineate an a priori sampling strategy for missions to terrestrial planets must be simple. In the case of the Moon, for example, the simplest and most obvious plan that to sample both the highly-cratered, high-albedo highlands and less-cratered, low-albedo mare--has proven very useful. However in the case of Mars, multiple missions and/or roving samplers may prove expensive or infeasible. Thus, we may be limited to collecting samples from a single site, and, consequently, consideration of sampling strategies for a Mars mission is more critical than for the more-accessible Moon.
