NASA'S GERMBUSTER

摘要

"Protecting Earth from the scum of the universe, and the universe from the scum of Earth." what's the unofficial mission statement of NASA's Planetary Protection Advisory Committee, and Norine Noonan's job. A cell biologist at the College of Charleston in South Carolina, Noonan chairs this committee charged with keeping future spacecraft from contaminating distant worlds and vice-versa. One dollop of misplaced filth could nullify years of research - or a few million lives. Makes you wonder how Noonan manages to sleep at night.
