From page 26...
... radiodurans cells support two findings. First, it must be assumed that any forward contamination of small bodies with terrestrial microorganisms would essentially be permanent, over mission timeframes of thousands of years, and this could complicate scientific efforts in the search for life, even though terrestrial microbes would not proliferate in vacuo.
From page 27...
... Although some small bodies have been imaged with high resolution radar or adaptive optics data, currently most information about small solar system bodies is derived from ground-based observations that show the objects merely as points of light. Very little is known about Centaurs, Trojans, and even outer Main Belt asteroids (MBAs)
From page 28...
... Likelihood of Revisiting The foundational concept of planetary protection is the preservation of the scientific integrity of a body or region for future astrobiological studies of that body or region. If there is no likelihood that a target will be revisited for astrobiological study, there is no compelling reason to not categorize a mission to that target as Category I
