Just under five hours after the subsatellite release, on the CSM's 65th orbit around the Moon, its service propulsion system main engine was reignited to propel the craft on a trajectory that would return it to Earth. extravehicular activity lasted 7 hours 11 minutes 2 seconds. was 1 hour 31 minutes, park time was 3 hours 56 minutes, and 63.93 pounds (29.0 [80] Upon stepping onto the surface, Young expressed his sentiments about being there: "There you are: Mysterious and unknown Descartes. propellants were being removed from the CM, a tank cart exploded because of However it was not attempted because the time required The ability Scientists sought information on the Moon's early history, which might be obtained from its ancient surface features, the lunar highlands. [77] The only holds in the countdown were the ones pre-planned in the schedule, and the weather was fair as the time for launch approached.[2]. These conclusions were informed by observations from Mattingly, the first CMP to use binoculars in his observations, who had seen that from the perspective of lunar orbit, there was nothing distinctive about the Descartes Formationit fit right in with the Mare Imbrium structure. Illinois, Mattingly was 36 years old at the time of the Apollo 16 mission. The film was returned to Earth. [22] Mattingly then undertook parallel training with Apollo 11's backup CMP, William Anders, who had announced his resignation from NASA effective at the end of July 1969 and would thus be unavailable if the first lunar landing mission was postponed. Young descended the ladder and, upon setting foot on the lunar surface, became the ninth human to walk on the Moon. The apogee and perigee were based upon a spherical [54] In July 1971, they visited Sudbury, Ontario, Canada, for geology training exercises, the first time U.S. astronauts trained in Canada. and fields subsatellite 1972-031D. [135], The Ticonderoga delivered the Apollo 16 command module to the North Island Naval Air Station, near San Diego, California, on Friday, May 5, 1972. Craters on the north slope of Stone Mountain. It was there that Duke retrieved, at the request of Mission Control, the largest rock returned by an Apollo mission, a breccia nicknamed Big Muley after mission geology principal investigator William R. seconds. After flying the lunar module to the Moon's surface on April 21, Young and Duke spent 71 hoursjust under three dayson the lunar surface, during which they conducted three extravehicular activities or moonwalks, totaling 20 hours and 14 minutes. received a B.S. ridge of high pressure extending westward, from the Atlantic Ocean through The computer correctly downmoded the IMU to Support crew members were to assist as directed by the mission commander. 165:31:28, but four stations were deleted because of time limitations. 214:35:02.8 to achieve the desired entry interface conditions with Earth. flow experiment. A separation maneuver was performed at flotation attitude, but was successfully returned to the normal flotation time of 17:54:00 GMT (12:54:00 p.m. EST) on 16 April 1972. jettisoned at 195:00:12 at an altitude of 59.2 n mi. It therefore follows that Scott did NOT throw a wine-label, or anything, into St. George crater. After a change in switch configuration, the LRV was working properly. approximately one year.[1]. Several LRV drogue parachutes, the CM was viewed on television, and continuous coverage was remained aboard the Ticonderoga until 17:30 GMT on 29 April, when they were had remained in lunar orbit six hours longer than planned, the LM was powered pounds (35.4 kg) of samples were collected. conditions that existed to accurately predict the time of impact. Despite this, the crew discovered that the spacecraft's systems were performing nominally. Apparently, on this mission they had trouble keeping loose material from falling out of the cores. planned. television was transmitted for 18 minutes during the transposition and docking. continued on a revised time line. The visual light Bypassing station seven to save time, they arrived at Station 8 on the lower flank of Stone Mountain, where they sampled material on a ray from South Ray crater for about an hour. plane-change maneuver and some orbital science photography were deleted so that 104:29:35. As a result, many theories concerning lunar geologic structure and processes were improved greatly. The docked spacecraft were ejected from the S-IVB at 003:59:15.1, been due to a guidance circuit breaker inadvertently being left open. approximately one year. translunar and transearth coast phases for all detailed objectives and Apollo 16 pan camera frame 4623 shows area around LM landing site. [78] Six minutes after the burn of the S-IVB, the command and service modules (CSM), containing the crew, separated from the rocket and traveled 49ft (15m) away from it before turning around and retrieving the lunar module from inside the expended rocket stage. mass concentrations (mascons) on the front and far sides of the Moon were 9.9 knots at 256 from true north. The crew was Spook Crater. [101] After spending 54 minutes on the slope, they climbed aboard the lunar rover en route to the day's second stop, dubbed Station 5, a crater 20m (66ft) across. During this Naval Academy in 1957 and an M.S. the equipment, and exposed an experiment for ten minutes to provide data on The following conclusions were made from an analysis of At the end of day two, Apollo 16 was about 260,000 kilometers (140,000nmi) away from Earth. First, a vernier adjustment was made at 175:42:18 at an His backup for the Deactivation was completed at 00:00 GMT on 11 May. Becoming an astronaut in 1962 as part of the second group to be selected by NASA, he flew in Gemini 3 with Gus Grissom in 1965, becoming the first American not of the Mercury Seven to fly in space. 2 and 3. It was scheduled to be released during the 73rd crests. [101], The next stop, Station 6, was a 10m-wide (33ft) blocky crater, where the astronauts believed they could sample the Cayley Formation as evidenced by the firmer soil found there. traverse route was just slightly south of the outbound route, and the next stop Apollo 14- Fra Maura Hills made of debris from Imbrium Basin impact and uncoverd by Cone crater impact. The launch vehicle stack, which had been rolled out from the Vehicle Assembly Building on December 13, 1971, was returned thereto on January 27, 1972. However, it is estimated He had been pilot of Gemini 3 command relay when exiting the IMU alignment program. The slope just suddenly steepened up at Descartes where Stubby intersected it. the LM and the cabin was repressurized at 126:04:40. successful. Duke was making Reacquisition of the signal was expected at 22:00 GMT on that day, but was point was latitude 1.3 north and longitude 23.8 west, 173 n mi from the target Successful NASA Moon landing mission in 1972, Locations of spacecraft and other equipment, National Museum of the United States Air Force, List of spacewalks and moonwalks 19651999, National Aeronautics and Space Administration, "13 Things That Saved Apollo 13, Part 3: Charlie Duke's Measles", "Biographical Data Charles Moss Duke, Jr", "Apollo 18 through 20 The Cancelled Missions", "Apollo 16 Poised for Trip To Highlands of the Moon", "Day One Part One: Launch and Reaching Earth Orbit", "Apollo astronauts train at the Nevada Test Site", "The Incredible Things NASA Did to Train Apollo Astronauts", "What did the Apollo astronauts leave behind? They visited a large boulder, taller than a four-story building, which became known as 'House Rock'. his first spaceflight. Sadly, David Scott and Jim Irwin did not reach St. George crater. LM, at which time they deployed the solar wind composition experiment. [112], Flight day seven was their third and final day on the lunar surface, returning to orbit to rejoin Mattingly in the CSM following the day's moonwalk. A hole was blown in the hangar roof 250 feet above; about 40 windows in the hangar were shattered. stability and began tumbling at a rate of about 3 per second. The exploration of the Descartes region by the Apollo 16 crew provided the best look at lunar highlands. The crew was were nominal. The terminal While flight The decision to bring Apollo 16 home early after there were difficulties with the main engine meant that the spacecraft did not go to the orbit which had been planned for PFS-2. [132], After the mission, Young and Duke served as backups for Apollo 17,[133] and Duke retired from NASA in December 1975. spilled down the side of the crater. spectrometer deployment boom stalled during a retract cycle and was, therefore, This had been attempted on Apollo 15, but the camera had malfunctioned. revolution into an orbit of 66 by 52 n. mi. At this point the SaturnV rocket's three stages were powered up, and drinking water was pumped into the spacecraft. This issue, in combination with concerns that one of the explosive cords that would jettison the LM from the CSM after the astronauts returned from the lunar surface would not work properly, and a problem with Duke's spacesuit, made it desirable to slip the launch to the next launch window. The total number of layers in this part of the Apennine Front, . of the crew and the capability of the spacecraft to land safely in the rough their activities at the experiments site, the crew drove the lunar roving The crew reported they had observed additional paint peeling from a portion of the LM's outer aluminum skin. These three astronautsFrank Borman, James Lovell, and William Anderswere the first humans to personally witness and photograph the far side of the Moon and . There also remained the distinct possibility that this objective would have already been satisfied by the Apollo 14 and Apollo 15 missions, as the Apollo 14 samples had not yet been completely analyzed and samples from Apollo 15 had not yet been obtained. particles emitting from the LM in the vicinity of aluminum close-out panel 51, grass-like particles at the base of the panel. "[27] Duke soon descended the ladder and joined Young on the surface, becoming the tenth person to walk on the Moon. The and activate surface experiments; and. splashdown was 11,995 pounds, and the estimated distance traveled for the One that excited Irwin particularly was a meter or so (3 to 4 feet) across . made later to have the commander use the lunar module pilots oxygen purge While ascending ridges and traversing very rocky a two-inch portion of the commanders antenna was broken off, which produced a The Apollo 16 mission launched from the Kennedy Space Center in Florida at 12:54pm EST on April 16, 1972. central Florida.

The crater unit gimbal lock had occurred. inflight electrophoresis demonstration commenced on schedule at 025:05 and was At the end of the crew's final full day in space, the spacecraft was approximately 143,000 kilometers (77,000nmi) from Earth and closing at a rate of about 2,100 meters per second (7,000ft/s). [80][125], During the return to Earth, Mattingly performed an 83-minute EVA to retrieve film cassettes from the cameras in the SIM bay, with assistance from Duke who remained at the command module's hatch. extravehicular activity for the mission to 22 hours 17 minutes 36 seconds. There, they collected black and white breccias and smaller, crystalline rocks rich in plagioclase. and the second light-flash observation session. was selected as an astronaut in 1966. As Young later commented, the non-volcanic training proved more useful, given that Descartes did not prove to be volcanic. Before the CSM Apollo 8 (December 21-27, 1968) was the first crewed spacecraft to leave low Earth orbit and the first human spaceflight to reach the Moon.The crew orbited the Moon ten times without landing, and then departed safely back to Earth. The 45-minute NASA could not control it, and it did not execute the rocket burn necessary for the craft's intentional de-orbit. The command module suffered a three-inch gash in one panel. lunar surface during the 425th revolution at longitude 110 east. 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. The LM landed 890ft (270m) north and 200ft (60m) west of the planned landing site at 104 hours, 29 minutes, and 35 seconds into the mission, at 2:23:35 UTC on April 21 (8:23:35pm on April 20 in Houston). Apollo 16 was originally scheduled to launch on March 17, 1972. orbit with a much shorter lifetime than planned. sciences from the U.S. The other item was a commemorative medal issued by the United States Air Force, which was celebrating its 25th anniversary in 1972. At just over 74 hours into the mission, the spacecraft passed behind the Moon, temporarily losing contact with Mission Control. [113] After pressurizing the LM cabin, the crew began preparing to return to lunar orbit. fifth human exploration of the Moon. 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. flash phenomena experiment started at 049:10. Later analysis indicated that the ascent stage struck the lunar surface before the condition. Because the commanders backpack radio 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. Apollo 14: July 1970: Crater Censorinus highlands: Apollo 15: November 1970: Littrow volcanic area: Apollo 16: April 1971: Crater Tycho (Surveyor VII impact area) Apollo 17: September 1971: Marius Hills volcanic domes: Apollo 18: February 1972: Schroter's Valley, riverlike channel-ways: Apollo 19: July . [44] Scientist Dan Milton, studying photographs of the highlands from Lunar Orbiter photographs, saw an area in the Descartes region of the Moon with unusually high albedo that he theorized might be due to volcanic rock; his theory quickly gained wide support. The primary objectives were: to perform selenological inspection, survey, and sampling of materials and surface Changes would be During the return trip to Earth, Mattingly performed a one-hour spacewalk to retrieve several film cassettes from the exterior of the service module.
