Apollo 16 was second of the so-called “J missions,” and was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly.
Young and Duke spent 71 hours on the lunar surface, during which they conducted three moonwalks, including journeys in the lunar rover.
Apollo 16 launched from the Kennedy Space Center in Florida on April 16, 1972, and returned to Earth 11 days, 1 hour, and 51 minutes later.
