On 24 July 1969 Apollo 11’s command module Columbia splashed down in the North Pacific. The three astronauts were taken aboard the carrier USS Hornet and, quarantined against lunar germs, met President Nixon.

On 24 July at 16:50 UTC, three days after leaving the Moon, Columbia came down 2,660 km east of Wake Island, 24 km from the carrier USS Hornet. Divers handed the crew biological isolation garments and wiped them down with disinfectant, in case they had brought back unknown germs from the Moon.
The three entered a Mobile Quarantine Facility aboard Hornet and met President Nixon through its window. “As a result of what you’ve done,” he said, “the world has never been closer together before.” The quarantine continued in Houston and was lifted on 10 August. The 21.5 kg of rock and soil they brought back is still being studied.
