How long did the Apollo 11 crew remain on the moon’s surface?

The Apollo 11 crew spent a total of 21 hours, 36 minutes, and 21 seconds on the moon. They conducted scientific activities during their time there and collected 47 pounds of lunar material samples to be brought back to Earth for study.

Neil Armstrong became the first human ever to set foot on the moon when he stepped off the ladder of the lunar module Eagle at 10:56pm EDT on July 20, 1969.

The crew left the moon’s surface and began their return voyage back to Earth on July 21, 1969. The Apollo 11 astronauts splashed down in the Pacific Ocean 900 miles southwest of Hawaii at 12:50pm EDT on July 24, 1969. They were recovered by recovery forces onboard the USS Hornet and returned safely home.

The Apollo 11 mission was a huge success, paving the way for future lunar exploration. It made history as the first manned mission to land on the moon and return safely back to Earth. The mission demonstrated that humans could indeed explore outer space and survive in harsh conditions outside of Earth’s atmosphere.
