... Locating these areas and locating sites that are shielded from the powerful atmospheric ultraviolet radiation and the powerful surface oxidants will require subsurface sampling.

... In 1974 the Board also recommended as preparation for a sample return mission and as an interim cost-effective program "... a Mariner polar orbiter mission and Pioneer survivable hard lander and probe mission...." Although the proposed interim mission would provide invaluable information on geochemical and geophysical characteristics of the Martian surface and interior, either the mission or its scientific payload would have to be supplemented to provide the biological characterizations required prior to decisions on the specifics of the sample return mission.
