Forward Contamination, Microbial Resilience, and the Ethics of Seeding Life Beyond Earth

To the point

James Lovelock and Lynn Margulis describe Earth as a self-regulating system, and this idea raises concerns about contaminating other worlds because microbes can survive and exchange genes, as shown by Lenski’s E. coli work, Cuatro Ciénegas Basin, the human microbiome, and spaceflight effects, guiding cautious policy under UN rules.

Man and his spaceships: Vehicles for extraterrestrial colonization?

The resiliency and adaptive ability of microbial life in real time on Earth relies heavily upon horizontal gene transfer. Based on that knowledge, how likely is earth based microbial life to colonize extraterrestrial targets such as Mars? To address ...
