A policy paper is urging NASA to incorporate a biocontainment facility into its planned lunar base to protect Earth from potentially hazardous biotic contaminants originating in space. The recommendation comes as the agency advances plans for a sustained human presence on the moon.

The proposed facility would serve as a quarantine zone for samples returned from other worlds, particularly Mars, where unknown microorganisms could pose a threat to terrestrial ecosystems. Researchers argue that placing such a facility on the moon, rather than on Earth, significantly reduces the risk of accidental contamination.

The paper does not provide specific cost estimates or timelines for construction, but it frames the facility as a critical component of any long-term lunar infrastructure. Without it, the authors warn, the return of extraterrestrial materials could carry unacceptable biological risks.

If adopted, the initiative would mark a major shift in planetary protection protocols, which currently rely on Earth-based labs. A lunar facility would also enable more ambitious sample-return missions by providing a safer staging ground for analysis before materials are transported home.

The recommendation is likely to spark debate among space agencies and private partners, who must balance scientific ambition with biosafety concerns. No official response from NASA has been issued as of the article's publication.
