Planetary Protection (PP) is a scientific discipline that aims to protect other celestial bodies from microorganisms found on Earth by preventing forward and backward contamination. Forward contamination is bringing life from Earth to a given celestial body and backward contamination is preventing contamination of eventual sample return missions from Mars back to Earth. PP verifies that NASA Planetary Protection requirements are met in part via the NASA Standard Assay in order to support the launch approval process and to comply with international law. The NASA Standard Assay verifies these bioburden requirements by quantifying any aerobic, heterotrophic, and heat-shock resistant isolates. …

Increasing efforts to find and study habitable conditions and the possibility of life on extraterrestrial cosmic bodies have also deepened the need for planetary protection advancements to prevent possibilities of forward and backward contamination. Despite stringent precautions to ensure spacecraft cleanliness, a number of spore-forming bacteria, including the biofilm forming strain, Bacillus horneckiae have been isolated from spacecraft associated surfaces. B. horneckiae spores have demonstrated unusually high resistance to rigorous sterilization procedures, and extreme conditions, including intense UV radiation. This exceptionally high tolerance of extreme conditions demonstrated by spore-forming bacteria highlighted the need to assess the viability of these microbes …
