Apollo 16 - Three days(almost) on the moon

Apollo 16 (April 16 – April 27, 1972) was the tenth manned mission in the Apollo program, the next to last one to land on the Moon and the first to land in the lunar highlands.  John Young and Charles Duke spent 71 hours—just under three days—on the lunar surface, during which they conducted three extra-vehicular activities or moonwalks, totaling 20 hours and 14 minutes. The pair drove the Lunar Roving Vehicle 16.6 mi. On the surface, Young and Duke collected 211 lb. of lunar samples for return to Earth. Command Module Pilot Ken Mattingly orbited in the Command/Service Module (CSM) above to perform observations. Mattingly spent 126 hours and 64 revolutions in lunar orbit. After Young and Duke rejoined Mattingly in lunar orbit, the crew released a subsatellite from the Service Module (SM). During the return trip to Earth, Mattingly performed a one-hour spacewalk to retrieve several film cassettes from the exterior of the Service Module.  Apollo 16's landing spot in the highlands was chosen to allow the astronauts to gather geologically older lunar material than the samples obtained in the first four landings, which were in or near lunar maria. Samples from the Descartes Formation and the Cayley Formation proved that the formations were not volcanic in origin, as was previously thought. (An artist has taken on this mission, but I need all three of these brave men.)

John Watts Young (born September 24, 1930), is a retired, US Navy Captain and aviator, test pilot, and aeronautical engineer. In 1965, Young flew on the first manned Gemini mission. In 1969 was the first person to orbit the Moon alone during Apollo 10. He became the ninth person to walk on the Moon as Commander of the Apollo 16 mission in 1972. Young had the longest career of any astronaut, becoming the first person to make six space flights over the course of 42 years of active NASA service and is the only person to have piloted, and been commander of, four different classes of spacecraft: Gemini, the Apollo Command/Service Module, the Apollo Lunar Module, and the Space Shuttle. He is one of only three people to have twice journeyed to the Moon. Young set a speed record driving the Lunar Rover on the Moon's surface. He also commanded two Space Shuttle flights, including its first launch in 1981, and served as Chief of the Astronaut Office from 1974–1987. Young retired from NASA in 2004.

                               

Thomas Kenneth “Ken” Mattingly II (born March 17, 1936),  is a Naval Aviator and Rear Admiral in the US Navy who flew on the Apollo 16 and two Space Shuttle missions. He had been scheduled to fly on Apollo 13, but was held back due to exposure to German measles, which he did not contract. He later flew as Command Module pilot for Apollo 16. Mattingly performed a space walk to retrieve film and data packages from the science bay on the side of the service module. Following his return to Earth, Mattingly served in astronaut management positions in the Space Shuttle development program. He was named to command the fourth and final orbital test flight of the Space Shuttle Columbia, launched from Kennedy Space Center, Florida, on June 27, 1982. Mattingly served as the spacecraft commander of the first Space Shuttle Department of Defense mission, launched from Kennedy Space Center, Florida in 1985. 

Charles Moss "Charlie" Duke, Jr. (born October 3, 1935), is a retired Brigadier General in the US Air Force. During his career he was an engineer and a test pilot.  During Apollo 11, he became the voice of a Mission Control. His southern drawl was familiar to everyone watching the long landing that almost expended all of the Lunar Module Eagle's fuel. Duke's first words to the Apollo 11 crew on the surface of the Moon were flustered, "Roger, Twank... Tranquility, we copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. Thanks a lot!" As Lunar Module Pilot for Apollo 16 in 1972, he became the tenth and youngest person to walk on the Moon. Duke has logged 4,147 hours flying time, which includes 3,632 hours in jet aircraft; and 265 hours in space, plus 20 hours and 15 minutes of extra-vehicular activity.A resident of New Braunfels, Texas, he is currently Chairman of the Board of Directors of the Astronaut Scholarship Foundation.
