Planetary protection sounds like some sort of essential cosmic condom.
The ongoing quest to look for life on other planetary bodies demands that we don’t haul life from Earth via spacecraft, a downer of a dilemma called forward contamination.
At present, spacecraft microbial reduction protocols for outward-bound spacecraft prioritize bacterial spores. But it appears there might be a worrisome breach in planetary protection strategies.
A new study has identified 23 fungal strains isolated from NASA spacecraft assembly cleanrooms that are capable of surviving a pre-launch cleansing of ultraviolet radiation exposure.
