NASA went to extraordinary lengths to show that what was brought back from the moon that time was safe.
NASA fed some of its precious Apollo 11 lunar samples to cockroaches
“We had to prove that we weren’t going to contaminate not only human beings, but we weren’t going to contaminate fish and birds and animals and plants and you name it,” said Charles Berry, head of medical operations during Apollo, in an oral history. “Any of the Earth’s biosphere, we had to prove we weren’t going to affect it. So we had to develop an amazing program that was carried off really for three flights’ worth. A lot of trouble.”
50 years later, those samples are still studied.
How NASA has preserved Apollo moon rocks for 50 years
“May I hold it?” I ask Krysher. No dice. I had to ask, even though Zeigler had warned me in an e-mail before I arrived: “We have pretty strict rules about people putting their (gloved) hands in the cabinets to touch samples. Basically, it’s an only-if-you-walked-on-the-moon rule.”
Keeping pristine samples away from curious fingers allowed scientists to make one of the most surprising lunar discoveries of the last 50 years: The moon is wet. Over the last decade, scientists have found hundreds of times more water in lunar samples than researchers in the Apollo era realized existed.
A visit to NASA’s moon rock central
Science News astronomy writer Lisa Grossman went behind the scenes at NASA’s pristine sample lab at Johnson Space Center in Houston this spring and saw moon rocks up close — or as close as non-astronauts can get.
