Story summary

Researchers at the University of Houston found Tersicoccus phoenicis can evade detection in the National Aeronautics and Space Administration (NASA) clean rooms by entering a dormant state, reducing its metabolism.
This raises concerns about current sterilization effectiveness in spacecraft assembly and other settings.
The study calls for verification that accounts for dormancy to reduce contamination risk and support planetary protection.
