Apollo 11 spent 21 hours 36 minutes on the lunar surface. The rocket engine on the ascent stage of Eagle fired for seven minutes returning the astronauts to lunar orbit, leaving the descent stage on the moon. Just over three hours later, the Lunar Module and Command Space Module were docked, allowing the two moonwalkers to transfer themselves and their lunar samples back into the Command Module. Two hours later, Eagle was released, destined to crash into the moon in a couple of weeks.
