[space] Martians Might Be Real. That Makes Mars Exploration Way More Complicated … A look at the job of the woman whose job at NASA is to make sure we don’t kill Martians before we find them … ‘If alien life exists, researchers will of course want to study how it originated and evolved—to glimpse what planetary scientist Chris McKay calls a “second Genesis.” And to prevent false leads, humans have to be careful not to muddy space with our own trail of bacteria. Another less official rationale for today’s planetary protection policy is ecological—you might even call it anticolonial. Essentially, Conley’s office serves to prevent NASA from doing to Martians what European explorers did to Native Americans with smallpox. Because Mars lacks Earth’s history of abundant life, it has that much more raw material for Earth’s bacterial stowaways to devour—should any of them, say, come into contact with water, find a niche they can survive in, and start to reproduce. “The whole planet is a dinner plate for these organisms,” she says. “They will eat Mars.” Conley wants to make sure we at least know whether Martian life exists before we introduce an invasive species that will wipe it out.’
