摘要：

The origination of duration and distance requirements on planetary mobility systems (generally, rovers) are reviewed in detail. It is found that a 'clean' flow down from scientific objectives to requirement to capability is rarely presented. Rather, the historical record shows that the capability of emerging designs has been adopted post-hoc as a requirement, simple comparative superiority to predecessor missions has been invoked in competitive situations, or the requirement has been driven by capability of other elements of a mission architecture, such as delivery precision or astronaut life support. These deviations from the idealized systems engineering process have nonetheless resulted in missions that have generally been considered highly successful. (C) 2019 COSPAR.
