Apollo 16 NASA Documentary - Nothing So Hidden - 1972 - 5th Moon Landing

NASA APOLLO 16 LUNAR MISSION w/ LUNAR ROVER "NOTHING SO HIDDEN" This 1972 NASA documentary on the flight of Apollo 16 includes film footage from the mission’s launch, lunar landing, and in the “moon buggy” before finally returning the crew (astronauts John W. Young, Thomas K. Mattingly, II, and Charles M. Duke, Jr.) to Earth. Apollo 16 was the fifth moon landing of Project Apollo, and the 10th manned mission in the Apollo program. It was the second mission to utilize a Lunar Rover (Lunar Roving Vehicle, LRV) during lunar EVAs (moonwalks). The film shows the launch (mark 02:56), landing (09:43), and the three lunar traverses in the highland region of the moon, near the crater Descartes. Includes an astronaut's eye view from the Rover, lunar Grand Prix, discovery of the house-sized rock, lunar lift-off, and EVA 173,000 miles above Earth. Microphones and cameras in Mission Control record the emergency problem solving during the pre-landing crisis and the reactions of scientists on Earth as the astronauts explore the Moon.

Young and 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 (LRV), the second produced and used on the Moon, 26.7 kilometers (16.6 mi). On the surface, Young and Duke collected 95.8 kilograms (211 lb) of lunar samples for return to Earth, while 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.
