I recall that one of the Apollo missions, maybe Apollo 12, landed nearby an automated probe, maybe a Surveyor probe, and one of the astronauts, maybe Pete Conrad, cut a bit of the probe off put it in a back and took it back to Earth. On Earth a scientist found that there were microbes on the bit of metal. They speculated that a technician must have sneezed on the Surveyor probe before it left Earth. The scientist scraped a sample of snot from the scrap metal and put it in a dish to see what would happen. Surprisingly the microbes were alive.
