Category IVb missions -- i.e., those carrying instruments designed to investigate extant martian life -- must meet Category IVa requirements plus: "the entire landed system is restricted to a surface bioburden of ≤30 spores [note 4] or to levels of bioburden reduction driven by the nature and sensitivity of the particular life-detection system;" or "the subsystems which are involved in the acquisition, delivery, and analysis of samples used for life detection must be sterilized to these levels, and a method of preventing recontamination of the sterilized subsystem and the containment of the material to be analyzed is in place." Category IVc missions -- i.e., those accessing special regions on Mars, even if not carrying life-detection instrument -- must meet Category IVa requirements plus: "if the landing site is within the special region, the entire landed system is restricted to a surface bioburden level of ≤30 spores (note 4)
