Following the LM inspection, the crew reviewed checklists and procedures for the following days in anticipation of their arrival and the Lunar Orbit Insertion (LOI) burn.

Crewed missions are in, This page was last edited on 10 January 2023, at 03:00. The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. [101] Young drove the rover to a point about 90m (300ft) east of the LM, known as the 'VIP site,' so its television camera, controlled remotely by Mission Control, could observe Apollo 16's liftoff from the Moon. in aeronautics and

Geologists feared, however, that samples obtained from the crater might have been contaminated by the Imbrium impact, thus preventing Apollo 16 from obtaining samples of pre-Imbrium material. Major Charles Gordon Fullerton (USAF), Colonel James Benson Irwin (USAF), Haise,

One reason why Descartes had been selected was that it was visually different from previous Apollo landing sites, but rocks from there proved to be closely related to those from the Fra Mauro Formation, Apollo 14's landing site. At just over 74 hours into the mission, the spacecraft passed behind the Moon, temporarily losing contact with Mission Control.

[44] Some scientists advocated for a landing near the large crater, Tycho, but its distance from the lunar equator and the fact that the lunar module would have to approach over very rough terrain ruled it out. A hole was blown in the hangar roof 250 feet above; about 40 windows in the hangar were shattered. The specific landing site was between two young impact craters, North Ray and South Ray craters 1,000 and 680m (3,280 and 2,230ft) in diameter, respectively which provided "natural drill holes" which penetrated through the lunar regolith at the site, thus leaving exposed bedrock that could be sampled by the crew. At the request of Young and Duke, the moonwalk was extended by ten minutes. grass-like particles at the base of the panel. A scheduled
[71] Measurements after the mission found that "soft" magnetism had returned to the sample, although at a lower intensity than before. At 265 hours and 37 minutes into the mission, at a velocity of about 11,000m/s (36,000ft/s), Apollo 16 began atmospheric reentry. Lunar module

[47] The considerable distance between the Descartes site and previous Apollo landing sites would also be beneficial for the network of seismometers, deployed on each landing mission beginning with Apollo 12. Instead, the two craft kept station, maintaining positions close to each other. conditions encountered during ascent were 50.7 knots at 257 from true north at

Young descended the ladder and, upon setting foot on the lunar surface, became the ninth human to walk on the Moon. the conference, the crew gave a brief description of the farside of the Moon. Because of the delay, Young and Duke began their descent to the surface at an altitude higher than that of any previous mission, at 20.1 kilometers (10.9nmi).

"[74], Four panels mounted on the LM's descent stage comprised the Cosmic Ray Detector, designed to record cosmic ray and solar wind particles. Duke was then aged 36; no younger human has ever walked on the lunar surface. It was the second of Apollo's "J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV).

In order to improve Young's and Duke's sleep schedule, the third and final moonwalk of the mission was trimmed from seven hours to five.

The ascent stage eventually crashed into the lunar surface nearly a year after the mission. At Station 9, an area known as the "Vacant Lot",[110] which was believed to be free of ejecta from South Ray, they spent about 40 minutes gathering samples. Subsequently, Roosa and Mitchell were assigned to the backup crew, while Pogue and Carr were reassigned to the Skylab program where they flew on Skylab 4. operating nominally. Samples obtained from this boulder delivered the final blow to the pre-mission volcanic hypothesis, proving it incorrect. central Florida. astronautics from the Massachusetts Institute of Technology in 1964. Geologists realized that they had been so certain that Cayley was volcanic, they had not been open to dissenting views, and that they had been over-reliant on analogues from Earth, a flawed model because the Moon does not share much of the Earth's geologic history. Using two different sizes of polystyrene particles, one size colored red and one blue, separation of the two types via electrophoresis was achieved, though electro-osmosis in the experiment equipment prevented the clear separation of two particle bands. 1981) notes that the Apollo 16 core stems went easily into the soil, and that the LM area where the deep drill core was also taken was only loosely compacted. the Cape Kennedy launch area was experiencing fair weather resulting from a

[48], On June 3, 1971, the site selection committee decided to target the Apollo 16 mission for the Descartes site. [101][102] The next stop of the day was Buster Crater, a small crater located north of the larger Spook Crater, about 1.6km (0.99mi) from the LM. Had Anders left NASA before Apollo 11 flew, Mattingly would have taken his place on the backup crew. Oh, that first foot on the lunar surface is super, Tony! Nevertheless, no Apollo mission had actually visited the lunar highlands. Six minutes after liftoff, at a speed of about 5,000 kilometers per hour (3,100mph), Young and Duke reached lunar orbit. Muehlberger. However, navigation heading was
During the training exercises the astronauts did not wear space suits, but carried radio equipment to converse with each other and England, practicing procedures they would use on the lunar surface. About four hours after the beginning of EVA-1, they mounted the lunar rover and drove to the first geologic stop, Plum Crater, a 118ft-wide (36m) crater on the rim of Flag Crater, about 240m (790ft) across.
