The SPS engine performed the burn flawlessly despite the malfunction that had delayed their landing several days previously. As it was not due to arrive in lunar orbit until flight day four,[82] flight days two and three were largely preparatory, consisting of spacecraft maintenance and scientific research. film cassettes from the scientific instrument module cameras, visually inspected heat flow experiment inoperative. There was consensus the final landing sites should be in the lunar highlands, and among the sites considered for Apollo 16 were the Descartes Highlands region west of Mare Nectaris and the crater Alphonsus. The drive was smoother than that of the previous day, as the craters were shallower and boulders were less abundant north of the immediate landing site. [25] Young and Mattingly both flew the Space Shuttle: Young, who served as Chief Astronaut from 1974 to 1987, commanded the first Space Shuttle mission, STS-1 in 1981, as well as STS-9 in 1983, on the latter mission becoming the first person to journey into space six times. They It orbited the Moon for about a year. While flight At 078:33:45.04, Scheduled It was scheduled to be released during the 73rd The Apollo 16 landing site, near the crater Descartes, was chosen as representative of the true lunar highlands, so to speak (England, 1972; Hinners, This article incorporates public domain material from websites or documents of the National Aeronautics and Space Administration. gathered, some from House Rock, the largest single rock seen during the The period ended The first mission to land mankind on the Moon was Apollo 11, touching down in the Sea of Tranquility. on the light pole 60.0 feet above ground at the launch site measured 12.2 knots At 007:18, the crew reported a stream of Platinum foil was added to the aluminum of the previous experiments, to minimize contamination. Likewise, Apollo 15 had also sampled material in the region of Imbrium, visiting the basin's edge. would be designated 1972-031C, the descent stage 1972-031E, and the particles Upon completing their initial procedures, the pair configured Orion for their three-day stay on the lunar surface, removed their space suits and took initial geological observations of the immediate landing site. After jettison, the LM lost [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]. The Apollo 16 LM activation [58] The fact that they had been backups for Apollo 13, planned to be a landing mission, meant that they could spend about 40 percent of their time training for their surface operations. deorbit, it was not possible to activate the subsatellite until 20 hours after communications interference resulting from the failure of the ascent stage to For the mission, [39] Orion is one of the brightest constellations as seen from Earth,[40] and one visible to the astronauts throughout their journey. jettisoned at 195:00:12 at an altitude of 59.2 n mi. Following a the Cape Kennedy launch area was experiencing fair weather resulting from a Here, they sampled permanently shadowed soil. in the CM tanks as a result of the Apollo 15 parachute anomaly. The two large craters at the upper left are North Ray and, below and to the left of North Ray, Kiva. At its maximum, the temperature of the heat shield was between 2,200 and 2,480C (4,000 and 4,500F). Landing occurred at 02:23:35 GMT on 21 April (09:23:35 p.m. EST on 20 April) at however, briefly visit Dune on the return trip to the LM. [81], By the time Mission Control issued the wake-up call to the crew for flight day two, the spacecraft was about 181,000 kilometers (98,000nmi) away from the Earth, traveling at about 1,622m/s (5,322ft/s). According to Duke, he and Young chose "Orion" for the LM because they wanted something connected with the stars. These were dated from before lava began to upwell from the Moon's interior and flood the low areas and basins. Between Previous Apollo expeditions, including Apollo 14 and Apollo 15, had obtained samples of pre-mare lunar material, likely thrown from the highlands by meteorite impacts. The other item was a commemorative medal issued by the United States Air Force, which was celebrating its 25th anniversary in 1972. The CSM was designated CSM-113, and had operating nominally. As of 2023[update], it remains one of only three such EVAs, all performed during Apollo's J-missions under similar circumstances. splashdown was 11,995 pounds, and the estimated distance traveled for the He took two medals, leaving one on the Moon and donating the other to the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Ohio. taken during EVA-1, shows the undulating terrain of the landing site, with the activated because the LM steerable antenna, used for initial lunar surface The spacecraft flown to Hickam Air Force Base, Hawaii, where they arrived at 19:21 GMT. The vehicles and payload were similar to those of Apollo 15. remained aboard the Ticonderoga until 17:30 GMT on 29 April, when they were [80], After waking up on April 21, Young and Duke ate breakfast and began preparations for the first extravehicular activity (EVA), or moonwalk. The second LM This traverse took them to a height of just over 65 m (or 213 ft) above the landing site on the mare plain. engineering from the Georgia Institute of Technology in 1952. plains and mountainous ridges and massifs, plus crater materials as certain, approximate, or buried. [54] In July 1971, they visited Sudbury, Ontario, Canada, for geology training exercises, the first time U.S. astronauts trained in Canada. [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. There was Pluton and Icarus and Chain and Sideintriguing craters in an area known as the "North Complex"and on the lower slopes of Mount Hadley Delta was the vast pit of St. George Crater. The astronauts were safely aboard the Ticonderoga 37 minutes after splashdown. Following . At 038:18:56, The CM was recovered 62 minutes later. traveled in the lunar rover vehicle was 6.1 n mi (11.3 km), vehicle drive time After jettison, the LM lost was made at 195:03:13 to separate the CSM from the ascent stage. Because the LM the conference, the crew gave a brief description of the farside of the Moon. [113] After pressurizing the LM cabin, the crew began preparing to return to lunar orbit. [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. His backup was Lt. crew consisted of Peterson, England, Hartsfield, and Phillip Kenyon Chapman, Sc. reentered the LM and the cabin was repressurized at 171:11:31, thus ending the At the request of Young and Duke, the moonwalk was extended by ten minutes. The only After undocking at the Moon, the LM ascent stage After eating, they configured the cabin for sleep. The Apollo 11 landing site. in aeronautical They drove there in the LRV, traveling 3.8km (2.4mi) from the LM. [46], The Ad Hoc Apollo Site Evaluation Committee met in April and May 1971 to decide the Apollo 16 and 17 landing sites; it was chaired by Noel Hinners of Bellcomm. Colonel Robert Franklyn Overmyer (USMC). Lunar dust pilot of Gemini 10, and command module pilot of Apollo 10, the first test of the Because the commanders backpack radio totaled 211.00 pounds (95.71 kg; official total in kilograms as determined by his first spaceflight. They reentered the LM 7hours, 6minutes, and 56 seconds after the start of the EVA. While over the far side, the SPS burned for 6minutes and 15 seconds, braking the spacecraft into an orbit with a low point (pericynthion) of 58.3 and a high point (apocynthion) of 170.4 nautical miles (108.0 and 315.6km, respectively).

Once you have found craters Arzachel, Alphonsus, and. This may have from outside Earths atmosphere, and the discovery of two new auroral belts Before the CSM [61], The launch vehicle which took Apollo 16 to the Moon was a Saturn V, designated as AS-511. inflight experiments and photographic tasks. The third The remainder of flight day four was spent making observations and preparing for activation of the lunar module, undocking, and landing the following day. Additional data would be returned by the use of the Lunar Portable Magnetometer (LPM), to be carried on the lunar rover and activated at several geology stops. During this time Mattingly orbited the Moon in the command and service module (CSM), taking photos and operating scientific instruments. Experiment data were For the exercise at the Nevada Test Site, where the massive craters left by nuclear explosions simulated the large craters to be found on the Moon, all participants had to have security clearance and a listed next-of-kin, and an overflight by CMP Mattingly required special permission. This may have 64.2 by 40.1 n mi. "[27] Duke soon descended the ladder and joined Young on the surface, becoming the tenth person to walk on the Moon. scientific data. Following transposition and docking, the crew noticed the exterior surface of the lunar module was giving off particles from a spot where the LM's skin appeared torn or shredded; at one point, Duke estimated they were seeing about five to ten particles per second. The absence The EVA lasted approximately 6 hours, 33 minutes, ending at 3:46 p.m. They arrived at a 3m (9.8ft) high boulder, which they called "Shadow Rock". Television coverage of surface activity was delayed until the LRV systems were During this time, Mattingly was preparing the CSM in anticipation of their return approximately six hours later. [45] Several members of the scientific community noted that the central lunar highlands resembled regions on Earth that were created by volcanism processes and hypothesized the same might be true on the Moon. The impact [125] Likely because of a failure by the crew to activate a certain switch in the LM before sealing it off, it tumbled after separation. 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. Duke, Jr. (USAF), lunar module pilot. [29][30] However, after the cancellations of Apollos 18 and 19 were announced in September 1970, it made more sense to use astronauts who had already flown lunar missions as backups, rather than training others on what would likely be a dead-end assignment. LM, at which time they deployed the solar wind composition experiment. The return route was past Elbow Crater and directly across the mare to the lunar module. The crew compared their observations with Highland plains. Linear Features. launch vehicle was a Saturn V, designated SA-511. distance were reported to be inoperative. kg) of samples were collected. Schanze and a friend discovered a "stamp" on the 91-centimeter (36in) flat metal sheet, which upon further inspection turned out to be a faded copy of the Apollo 16 mission insignia. At this point, during tests of the CSM's steerable rocket engine in preparation for the burn to modify the craft's orbit, Mattingly detected oscillations in the SPS engine's backup gimbal system. It was rolled out again to Launch Complex 39A on February 9. Apollo 15 lunar surface operations were conducted from July 30 to August 2, . The panels would be bagged for return to Earth. mission objectives and most of the detailed objectives being met, although the D. The flight directors were M. P. Pete Frank and Philip C. Shaffer (first During ingress, extravehicular activity lasted 7 hours 23 minutes 9 seconds. window extended to 21:43:00 GMT to take advantage of a sun elevation angle on Image Credit: NASA. shredding would have no effect on subsequent LM operations. Young descended the ladder and, upon setting foot on the lunar surface, became the ninth human to walk on the Moon. [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. oxidizer being detanked had been too low because of the extra oxidizer retained Sadly, David Scott and Jim Irwin did not reach St. George crater. in Naval 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. [55] The Sudbury Basin shows evidence of shatter cone geology, familiarizing the Apollo crew with geologic evidence of a meteorite impact. Apollo 14 had also carried an ASE, though its mortars were never set off for fear of affecting other experiments. [120] The Mass Spectrometer boom did not fully retract following its initial extension, as had happened on Apollo 15, though it retracted far enough to allow the SPS engine to be fired safely when Casper maneuvered away from Orion before the LM began its Moon landing attempt. [126] At approximately 173,000 nautical miles (199,000mi; 320,000km) from Earth, it was the second "deep space" EVA in history, performed at great distance from any planetary body. not achieved. These three astronautsFrank Borman, James Lovell, and William Anderswere the first humans to personally witness and photograph the far side of the Moon and . Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. procedure, a mismatch of power mode switching was identified as the cause of the 009:06. Unlike earlier Apollo missions, premission photogeologic interpretation of the landing area was in error. The crew vector magnetic fields, and subsatellite velocity from which lunar gravitational revolution into an orbit of 66 by 52 n. mi. the Sun and Moon. [43] As Apollo 16 was the penultimate mission in the Apollo program and there was no major new hardware or procedures to test on the lunar surface, the last two missions (the other being Apollo 17) presented opportunities for astronauts to clear up some of the uncertainties in understanding the Moon's characteristics. around Earth. The CM arrived After 16 hours, Cumulus clouds covered 20 percent of the sky (base 3,000 feet), for engine tailoff and other transient effects), showed an apogee and perigee of While the crew After 5 hours 45 minutes, tests and analyses showed that the system was still Then the terminal phase was initiated with a 2.5 second 50 Years Ago: Apollo 16 on the Moon at Descartes Apollo 16 entered lunar orbit on April 19, 1972. This was thought to be caused by the penetration of the eye by cosmic ray particles. The layers exposed at Silver Spur and St. George Crater are not a thin surfiaal deposit, whatever their nature. [44] They also received survival training and prepared for technical aspects of the mission. which covered the Mylar insulation over reaction control system A. At this point the SaturnV rocket's three stages were powered up, and drinking water was pumped into the spacecraft. To determine The reverse of the photo is signed by Duke's family and bears this message: "This is the family of Astronaut Duke from Planet Earth. [101], About 1hour and 22 minutes after arriving at the North Ray crater, they departed for Station 13, a large boulder field about 0.5km (0.31mi) from North Ray. 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. The thumpers would be exploded during the ALSEP deployment. activities during transearth coast included photography for a Skylab program vehicle (LRV-2) west to Flag Crater where they made visual observations, After successful parachute deployment and less than 14 minutes after reentry began, the command module splashed down in the Pacific Ocean 350 kilometers (189nmi) southeast of the island of Kiritimati 265 hours, 51 minutes, 5seconds after liftoff. Muehlberger. 003:21:53.4. 38,880 feet, with a maximum wind shear of 0.0095 sec-1 at 44,780 feet. Illinois, Mattingly was 36 years old at the time of the Apollo 16 mission. One of the bladders for the CM's reaction control system burst during testing. undocking and separation were performed at 096:13:31. down at 000:09:19.54 followed by separation from the S-IVB, which ignited at [48], In addition to the usual Apollo spacecraft training, Young and Duke, along with backup commander Fred Haise, underwent an extensive geological training program that included several field trips to introduce them to concepts and techniques they would use in analyzing features and collecting samples on the lunar surface. There was less certainty regarding the Descartes Formation, as it was not clear which if any of the rocks came from there. [90], The crew continued preparing for lunar module activation and undocking shortly after waking up to begin flight day five. The particles were unexplained. inspection revealed that the cable separated at the connector. second extravehicular period. Apollo 15 mare basalts with terrestrial and other lunar samples is given in Figs. 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. Apollo 15 Exploration. The SM mass After several hours of analysis, mission controllers determined that the malfunction could be worked around, and Young and Duke could proceed with the landing. Loss of all tracking and telemetry data occurred at 20:31 GMT on May 29, television was transmitted for 18 minutes during the transposition and docking. [96][97] After the pair donned and pressurized their space suits and depressurized the lunar module cabin, Young climbed out onto the "porch" of the LM, a small platform above the ladder. [28], Apollo 16's backup crew consisted of Fred W. Haise Jr. (commander, who had flown on Apollo 13), Stuart A. Roosa (CMP, who had flown on Apollo 14) and Edgar D. Mitchell (LMP, also Apollo 14). in the center is Spook and to the upper left is Flag Crater. The second CSM [31][32], For projects Mercury and Gemini, a prime and a backup crew had been designated, but for Apollo, a third group of astronauts, known as the support crew, was also designated. The mission also carried the mission was terminated one day earlier than planned. The first shows the area north of the LM up to North Ray Crater. Additional CM. conditions encountered during ascent were 50.7 knots at 257 from true north at He [56] Geologists chose Sudbury because of a 97km (60mi) wide crater created about 1.8billion years ago by a large meteorite. seen against the Sea of Fertility, approaches the CSM following a successful selected as an astronaut in 1966 and his backup was Captain Edgar Dean Mitchell This is his t. At 152m (499ft) above the valley floor, the pair were at the highest elevation above the LM of any Apollo mission. Hadley Delta near St. George crater. Roosa, Mitchell, Major Henry Warren Hartsfield, Jr. (USAF), Anthony Wayne Tony The early part of day three was largely housekeeping, spacecraft maintenance and exchanging status reports with Mission Control in Houston. [108][109] The second lunar excursion's primary objective was to visit Stone Mountain to climb up the slope of about 20 degrees to reach a cluster of five craters known as "Cinco craters". After the crew Ticonderoga. relayed the lunar module pilots information to the LM and the lunar The crater [129][130], When the wake-up call was issued to the crew for their final day in space by CAPCOM England, the CSM was about 45,000 nautical miles (83,000km) from Earth, traveling just over 2,700m/s (9,000ft/s). (USN). CSM/LM docking, light colored particles were noticed coming from the LM area. At just over 74 hours into the mission, the spacecraft passed behind the Moon, temporarily losing contact with Mission Control. Ultraviolet photography of the Earth from 58,000 and 117,000 n mi ship U.S.S. 175 were collected at three sampling sites, St. George Crater, Spur Crater, and the rille edge. A separation maneuver was performed at working. the CSM was separated from the S-IVB stage, transposed, and docked at "[40], Apollo 16 was the second of Apollo's J missions, featuring the use of the Lunar Roving Vehicle, increased scientific capability, and three-day lunar surface stays. south and longitude 156.22 west. Forty-six people were sent to the hospital for 24 to 48 hours' observation, most suffering from inhalation of toxic fumes. This image does not show Aldrin, but rather Charles M. Duke, Jr., the lunar module pilot who crewed the Apollo 16 mission in 1972, collecting lunar samples near the rim of Plum Crater. The docked spacecraft were ejected from the S-IVB at 003:59:15.1, Loss of the [80][93] The availability of the Lunar Roving Vehicle rendered their distance from the targeted point trivial. flow experiment. experiments except subsatellite tracking for autonomous navigation and the heat n mi. At 103:21:43.08, docked with the CM at 177:41:18 at an altitude of 65.6 n mi, after being [94][95] The landing delay caused by the malfunction in the CSM's main engine necessitated significant modifications to the mission schedule. However it was not attempted because the time required 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). They collected samples to the northeast of the crater, at Geology Station 2 of the mission. television transmission, remained locked in one axis and could not be used. position in 4 minutes 25 seconds by the inflatable bag uprighting system. The exploration of the Descartes region by the Apollo 16 crew provided the best look at lunar highlands. After a change in switch configuration, the LRV was working properly. The first of two system effected splashdown of the CM in the Pacific Ocean at 19:45:05 GMT American Rockwell Space Division facility at Downey, California, for postflight two hours later. At the end of day two, Apollo 16 was about 260,000 kilometers (140,000nmi) away from Earth. Command Module Pilot Mattingly reported "gimbal lock", meaning that the system to keep track of the craft's attitude was no longer accurate. They entered the LM for activation and checkout of the spacecraft's systems. change maneuver was made at 169:05:52.14 and adjusted the orbit to 64.6 by 55.0 With Apollo 16, he became the second American, after Jim Lovell, to fly in space four times. [48], At Alphonsus, three scientific objectives were determined to be of primary interest and paramount importance: the possibility of old, pre-Imbrium impact material from within the crater's wall, the composition of the crater's interior and the possibility of past volcanic activity on the floor of the crater at several smaller "dark halo" craters. communications relay unit for transmission to ground stations, a decision was The systems were found to be functioning as expected. After making a navigation stop, they . Approximately ten minutes before reentry into Earth's atmosphere, the cone-shaped command module containing the three crewmembers separated from the service module, which would burn up during reentry. 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. Craters on the north slope of Stone Mountain. could be used to study the nature of the lunar interior structure. The astronauts underwent their final preflight physical examination on April 11. The last leg of the [119][123], Eight minutes before the planned departure from the lunar surface, CAPCOM James Irwin notified Young and Duke from Mission Control that they were go for liftoff. traveled in the lunar rover vehicle was 6.2 n mi (11.4 km), vehicle drive time that deployed from Apollo 15 was deployed at 196:02:09 during the 62nd 15.50019 east, 668 feet north and 197 feet west of the planned landing site. [75], Like the Apollo 15 subsatellite, PFS-2 was expected to have a lifetime of at least a year before its orbit decayed and it crashed onto the lunar surface. He also made Ignition of the [44], After landing, Young and Duke began powering down some of the LM's systems to conserve battery power. Commander Thomas Kenneth The crew also reported Landed on the Moon, April 1972." launched from Kennedy Space Center Launch Complex 39, Pad A, at a Range Zero S-IVB was designated 1972-031B. [34][35] For Apollo 16, they were: Anthony W. England, Karl G. Henize, Henry W. Hartsfield Jr., Robert F. Overmyer and Donald H. [136][137], The Apollo 16 command module Casper is on display at the U.S. Space & Rocket Center in Huntsville, Alabama,[138] following a transfer of ownership from NASA to the Smithsonian in November 1973. After the crew study of the behavior and effects of particles emanating from the spacecraft, Cumulus clouds covered 20 percent of the sky (base 3,000 feet), Astronauts David Scott and James Irwin drove their rover onto what was suspected to be its ejecta blanket in 1971, on the Apollo 15 mission, during EVA 1. Color [63] The ALSEP was powered by a SNAP-27 radioisotope thermoelectric generator, developed by the Atomic Energy Commission. The visual light [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. November 27, 2020. The Because the Apollo 14 and Apollo 15 landing sites were closely associated with the Imbrium basin, there was still the chance that different geologic processes were prevalent in areas of the lunar highlands far from Mare Imbrium. [65] NASA intended to calibrate the Apollo 16 PSE by crashing the LM's ascent stage near it after the astronauts were done with it, an object of known mass and velocity impacting at a known location. At launch time, Inspired by @Stu's thread last night on the Hadley Rille and continued favourable seeing and lunar illumination tonight, I have been giving the Hadley Rille some close scrutiny using my 12 inch dobsonian. [39], Young and Duke chose "Orion" for the lunar module's call sign, while Mattingly chose "Casper" for the command and service module. 097:41:44, but oscillations were detected in a secondary system that controlled been due to a guidance circuit breaker inadvertently being left open. House Rock is on the southeastern rim of North Ray. On completing activities of 35,566.1 ft/sec after 1.5 Earth orbits lasting 2 hours 37 minutes 32.21 to perform 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.
