If we had a real chance of being harmed by life on the lunar surface, Covid 19 would be child’s play. The New York Times has an article, “Cosmic Luck: NASA’s Apollo 11 Moon Quarantine Broke Down,” indicates we were not really ready for any potential contamination during the Apollo program. The newspaper cites a recent study on the quarantine process, which noted:
As NASA prepared to land astronauts on the Moon in the 1960s, scientists and federal officials came to fear that they could bring lunar microorganisms back to Earth, with potentially grave consequences for human, plant, and animal life. To prevent this“back contamination,”representatives from NASA and a network of federal departments and services developed a protocol to quarantine astronauts, equipment, samples, and spacecraft exposed to lunar dust. Yet although NASA assured policy makers and an anxious public that it had implemented impermeable safeguards against the escape of lunar microorganisms, it had in fact prioritized likely risks to astronauts over unlikely risks to American society. To a degree previously unknown, the Apollo quarantine protocol suffered from numerous containment breaches that would likely have exposed the terrestrial biosphere to contamination—had lunar microorganisms actually existed.
Of course, now that we have landed on the moon and sent up multiple missions, the risk today is that we have contaminated the lunar surface, as noted in this second story from Futurism, “NASA Says There May Be Life on the Moon After All.” For instance, an earlier Israeli mission that crashed on the lunar surface was carrying thousands of microscopic Tardigrades. The story also cites meteors as a possible source of life that could have found refuge on the Moon.
I think I will put my money on the Tardigrades.
