“If we’re going to look for life on Mars, it would be really kind of lame to bring Earth life and find that instead,” Cassie Conley, NASA’s planetary protection officer, told the New York Times. “We have discovered that there are many more Earth organisms that have capabilities we didn’t expect,” Conley said in the new NASA video shown below.


As head of NASA's Office of Planetary Protection, Cassie Conley is responsible to assure that backward contamination –the possibility of alien life from extraterrestrial worlds hitchhiking back to Earth on one of our sample return missions, or even taking up residence in the bodies of the first Mars-bound astronauts–is prevented. Equally critical is to ensure that microbial Earth life does not hitchhike to potentially hospitable environments, like Jupiter’s ocean moon Europa or Mars, where it might thrive and create false positives of alien life.
