| These things were mainly publicity stunts. The supposed biohazard quarantine for returning Apollo astronauts was a theater performance, too. https://www.livescience.com/space/the-moon/the-apollo-moon-l... ("The Apollo moon landing was real, but NASA's quarantine procedure was not") https://www.nytimes.com/2023/06/09/science/nasa-moon-quarant... ("A review of archives suggests that efforts to protect Earth from contamination by any organism brought back from the lunar surface were mostly for show") |
Some Agriculture Department folks decided that their legal authority to quarantine soil samples brought into the U.S. applied to lunar soils, too. They insisted on building a three-week quarantine facility with slivers of lunar samples, exposed to "germ-free mice born by cesarean section." Only after the mice survived this ordeal was it safe to release the fuller batch of samples.
Another character insisted that the aluminum rock boxes be sealed, while on the moon, with gaskets of indium (soft, rare metal) which would deform to create a very tight seal. The geochemists on earth protested, in vain, that this procedure would ruin their hopes of doing any indium analysis of the samples themselves, shutting down an interesting line of research. No luck in changing the protocol. Turns out that the indium seals didn't work, and the rock boxes reached the earth-based quarantine facilities with normal air pressure anyway.
There's more silliness about trying to keep the lunar samples in a hard vacuum while designing rigidly mounted gloves that could be used to manipulate/slice/divide the samples without breaking the vacuum. Maybe we know today how to sustain flexible gloves in such an environment. We didn't, back then.
