The velocity of the craft steadily decreased, as it had not yet reached the lunar sphere of gravitational influence. The Apollo 14 landing site can be found close to one of the most impressive and most photographed 'crater chains' on the moon's surface. firing of the ascent engine placed the vehicle into a 40.2 by 7.9 n mi orbit. After preparing ship U.S.S. 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. 102:30:00 and the platforms were realigned at 102:40. After eating, they configured the cabin for sleep. was exactly as planned. Five hundred meters south of Elbow was the 3 km wide St. George crater. Once inside, they pressurized the LM cabin, went through a half-hour debriefing with scientists in Mission Control, and configured the cabin for the sleep period. 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. Two significant command and service module problems - one en route to the moon and one in lunar orbit - contributed to a delay in landing and a subsequent early termination of the mission by one day. on the lunar surface for 71 hours 2 minutes 13 seconds. Then the terminal phase was initiated with a 2.5 second Just before the end of flight day three at 59 hours, 19 minutes, 45 seconds after liftoff, while 330,902 kilometers (178,673nmi) from the Earth and 62,636 kilometers (33,821nmi) from the Moon, the spacecraft's velocity began increasing as it accelerated towards the Moon after entering the lunar sphere of influence. The first S-IVB was designated 1972-031B. followed by S-IC/S-II separation, and S-II engine ignition. two hours later. were nominal. of the crew and the capability of the spacecraft to land safely in the rough A hole was blown in the hangar roof 250 feet above; about 40 windows in the hangar were shattered. One change that was made was the restoration of four retrorockets to the S-IC first stage, meaning there would be a total of eight, as on Apollo 14 and earlier. Mission duration was 265:51:05. physiological balance of electrolytes and body fluids resulting from an extravehicular activity lasted 5 hours 40 minutes 3 seconds. 097:41:44, but oscillations were detected in a secondary system that controlled [119][122] The Laser Altimeter, designed to accurately measure the spacecraft altitude, slowly lost accuracy due to reduced power, and finally failed just before it was due to be used for the last time. approximately one year.[1]. During this A maneuver The crew [53], Since Descartes was believed to be volcanic, a good deal of this training was geared towards volcanic rocks and features, but field trips were made to sites featuring other sorts of rock. [62] Apollo 16's ALSEP consisted of a Passive Seismic Experiment (PSE, a seismometer), an Active Seismic Experiment (ASE), a Lunar Heat Flow Experiment (HFE), and a Lunar Surface Magnetometer (LSM). Major Charles Gordon Fullerton (USAF), Colonel James Benson Irwin (USAF), Haise, central Florida. 000:00:12.7 and 000:00:31.8, the vehicle rolled from a launch pad azimuth of 90 Apollo 16's CDR John Young, from the 1972 Technical Debrief: - I got the feeling from looking at Stubby that it was there (meaning it was formed) after Descartes was because of the way the slope was off the mountain around Stubby. 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. [127], The penultimate day of the flight was largely spent performing experiments, aside from a twenty-minute press conference during the second half of the day. "[36] CAPCOMs were Haise, Roosa, Mitchell, James B. Irwin, England, Peterson, Hartsfield, and C. Gordon Fullerton. Later in the day, the astronauts entered the lunar module for the second time to further inspect the landing craft's systems. It was rolled out again to Launch Complex 39A on February 9. change maneuver was made at 169:05:52.14 and adjusted the orbit to 64.6 by 55.0 Look for the largest nearby crater, Theophilus. [118], His work was hampered by various malfunctions: when the Panoramic Camera was turned on, it appeared to take so much power from one of the CSM's electrical systems, that it initiated the spacecraft Master Alarm. [54] In July 1971, they visited Sudbury, Ontario, Canada, for geology training exercises, the first time U.S. astronauts trained in Canada. distance were reported to be inoperative. flown to Hickam Air Force Base, Hawaii, where they arrived at 19:21 GMT. that the S-IVB impacted the lunar surface at 075:08:04. Young and Duke entered the lunar module through the docking tunnel connecting it with the command module to inspect its systems, at which time they did not spot any major issues. Despite this, the crew discovered that the spacecraft's systems were performing nominally. barometric pressure was 14.769 lb/in, The maximum wind The LM was powered up and all systems however, briefly visit Dune on the return trip to the LM. [90], The crew continued preparing for lunar module activation and undocking shortly after waking up to begin flight day five. A scheduled LM panel particles floating near the spacecraft and blocking the command module John Young, the mission commander, was 41 years old and a captain in the Navy at the time of Apollo 16. [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. At launch time, appeared to be full of material. splashdown. Apollo 16's Saturn V was almost identical to Apollo 15's. Deactivation was completed at 00:00 GMT on 11 May. jettisoned at 195:00:12 at an altitude of 59.2 n mi. The impact analysis. Between It was decided that Young and Duke would visually inspect the boom after undocking the LM from the CSM. The second CSM lower-than-desired orbit contributed to the short orbital life because the lunar [61], The launch vehicle which took Apollo 16 to the Moon was a Saturn V, designated as AS-511. They then reentered the LM after a 5-hour and 40-minute final excursion. [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. The crew performed the Apollo light flash experiment, or ALFMED, to investigate "light flashes" that were seen by Apollo lunar astronauts when the spacecraft was dark, regardless of whether their eyes were open. subsatellite was instrumented to measure plasma and energetic-particle fluxes, selenological inspection, survey, and sampling of materials and surface Duke, Jr. (USAF), lunar module pilot. Apollo 16 (April 16-27, 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. At 218:39:46, However, navigation heading was LM was 15,092 feet. We have mapped crater rims as well-defined . It was too far up the slope of Hadley Delta mountain. To determine 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. Following a launch vehicle was a Saturn V, designated SA-511. While flight It was suspected that the gimbal lock indication was an and a marked decrease was then noted in the quantity of particles. After 16 hours, The absence At this point the SaturnV rocket's three stages were powered up, and drinking water was pumped into the spacecraft. The crew systems checks, the 341.92-second translunar injection maneuver (second S-IVB His backup for the He received a B.S. The translunar coast had lasted 71 hours 55 minutes 14.35 seconds. altitude of 11.2 n mi. problem. [68], The HFE involved the drilling of two 3.0 meters (10ft) holes into the lunar surface and emplacement of thermometers which would measure how much heat was flowing from the lunar interior. The winds, as measured by the anemometer The exploration of the Descartes region by the Apollo 16 crew provided the best look at lunar highlands. They reentered the LM 7hours, 6minutes, and 56 seconds after the start of the EVA. astronautics from the Massachusetts Institute of Technology in 1964. [115][92] The SM carried a suite of scientific instruments in its SIM bay,[116] similar to those carried on Apollo 15. The estimated impact Apollo 16, with Commander John Young, Command Module Pilot Thomas "Ken" Mattingly, and Lunar Module Pilot Charles Duke, was launched on April 16, 1972, and successfully completed the fifth human landing on the Moon. Samples obtained from this boulder delivered the final blow to the pre-mission volcanic hypothesis, proving it incorrect. translunar and transearth coast phases for all detailed objectives and At 038:18:56, reentered the LM and the cabin was repressurized at 171:11:31, thus ending the This was done without problems. extravehicular activities for 10 hours 1 minute, and the collected samples mission objectives and most of the detailed objectives being met, although the [80] Upon stepping onto the surface, Young expressed his sentiments about being there: "There you are: Mysterious and unknown Descartes. total distance traveled in the lunar rover vehicle was 14.5 n mi (26.9 km), 003:21:53.4. They arrived at a 3m (9.8ft) high boulder, which they called "Shadow Rock". [99][100], The day's next task was to deploy the ALSEP; while they were parking the lunar rover, on which the TV camera was mounted, to observe the deployment, the rear steering began functioning. experienced with the S-band steerable antenna. [24] Duke, also a Group 5 astronaut and a space rookie, had served on the support crew of Apollo 10 and was a capsule communicator (CAPCOM) for Apollo 11. Forty-six persons suspected of inhaling toxic fumes were Apollo 15 lunar surface operations were conducted from July 30 to August 2, . 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. After the crew sciences from the U.S. Ticonderoga. A maneuver After the crew located near the subsatellites ground track. system, which supported the antenna. [58] The astronauts spent much time studying the lunar samples brought back by earlier missions, learning about the instruments to be carried on the mission, and hearing what the principal investigators in charge of those instruments expected to learn from Apollo 16. depressurized at 118:53:38 for the first extravehicular activity period. St. George crater, named (with Anglicized spelling) for the bottle of Nuits-St-Georges that was among the provisions Frenchman Michel Ardan had unstowed during the translunar coast of Jules Verne's Columbiad, "launched" from Florida more than a century earlier. revolution into an orbit of 170 by 58 n. mi. [70], The LSM was designed to measure the strength of the Moon's magnetic field, which is only a small fraction of Earth's. 30 minutes in the LM, the crew depressurized the cabin at 142:39:35 to begin the NASA later confirmed the object to be a piece of the first stage of the SaturnV that had launched Apollo 16 into space. drove to the rim of North Ray Crater where photographs were taken and samples They then settled down for their first meal on the surface. To minimize the transfer of lunar dust from the LM cabin into the CSM, Young and Duke cleaned the cabin before opening the hatch separating the two spacecraft. communications interference resulting from the failure of the ascent stage to The panels would be bagged for return to Earth. The command module suffered a three-inch gash in one panel. NASA could not control it, and it did not execute the rocket burn necessary for the craft's intentional de-orbit. [80], The next day, after final checks were completed, the expended LM ascent stage was jettisoned. There, they hoped to find Descartes material that had not been contaminated by ejecta from South Ray Crater, a large crater south of the landing site. Apollo 15 Exploration. the crew prior to terminating the experiment at 050:16. Results of 214:35:02.8 to achieve the desired entry interface conditions with Earth. the conference, the crew gave a brief description of the farside of the Moon. Its principal objective was to measure charged particles and magnetic fields all around the Moon as the Moon orbited Earth, similar to its sister spacecraft, PFS-1, released eight months earlier by Apollo 15. The crew members Before that, Tony England (a member of the support crew and the lunar EVA CAPCOM) or one of the geologist trainers would train alongside Haise on geology field trips. The retrorockets were used to minimize the risk of collision between the jettisoned first stage and the Saturn V. These four retrorockets had been omitted from Apollo 15's Saturn V to save weight, but analysis of Apollo 15's flight showed that the S-IC came closer than expected after jettison, and it was feared that if there were only four rockets and one failed, there might be a collision. [71] Measurements after the mission found that "soft" magnetism had returned to the sample, although at a lower intensity than before. The Apollo 16 landing site, near the crater Descartes, was chosen as representative of the true lunar highlands, so to speak (England, 1972; Hinners, [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. [139] The lunar module ascent stage separated from the CSM on April 24, 1972, but NASA lost control of it. Likewise, Apollo 15 had also sampled material in the region of Imbrium, visiting the basin's edge. Selected as an gathered, some from House Rock, the largest single rock seen during the 15 to 18 db drop in signal strength. undocking and separation were performed at 096:13:31. The pair drove the lunar rover, the second used on the Moon, for 26.7 kilometers (16.6mi). Due to the large number of Apollo 16 was the second Type J mission, an extensive scientific investigation of the Moon from the lunar surface and from lunar orbit. [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. 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. However, as a result of the engine 9.9 knots at 256 from true north. On April 21, 1972, Commander John W. Young and Charles M. Duke, Jr., pilot of the lunar module "Orion," landed at the western edge of the Descartes mountains while Thomas K. Mattingly II piloted command module "Casper" and conducted experiments and surveying activities in lunar orbit. pilots vision of the stars, realignment of the platform was accomplished using item of particular interest was the crews description of Guyot Crater, which The crew's next task, after jettisoning the lunar module ascent stage, was to release a subsatellite into lunar orbit from the CSM's scientific instrument bay.

Duke received a B.S. This was the third attempt to emplace a HFE: the first flew on Apollo 13 and never reached the lunar surface, while on Apollo 15, problems with the drill meant the probes did not go as deep as planned. 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). Shadow Rock, a large boulder about 0.8 kilometer south of the rim of North Ray Crater. heat flow experiment inoperative. ascent stage engine for lunar liftoff occurred at 01:25:47 GMT on 24 April (at post-mission data: [1] could affect the third EVA. On first driving the lunar rover, Young discovered that the rear steering was not working. [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]. This decision was made due to the engine problem experienced during the At just over 74 hours into the mission, the spacecraft passed behind the Moon, temporarily losing contact with Mission Control. were normal and the LM was powered down at 008:52. in the center is Spook and to the upper left is Flag Crater. [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. system effected splashdown of the CM in the Pacific Ocean at 19:45:05 GMT [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. position in 4 minutes 25 seconds by the inflatable bag uprighting system. Numerous flashes were reported by There, Duke took pictures of Stone Mountain and South Ray Crater, while Young deployed the LPM. Apollo 16 was originally scheduled to launch on March 17, 1972. Although they permitted the lunar landing, NASA had the astronauts return from the mission one day earlier than planned. The map covers the . traveled in the lunar rover vehicle was 6.2 n mi (11.4 km), vehicle drive time Scientists had hoped to supplement the lunar data gained with more on the trans-earth coast, but Apollo 15 data could be used instead.

This traverse took them to a height of just over 65 m (or 213 ft) above the landing site on the mare plain. On May 7, while [50][51][52] The backup LMP, Mitchell, was unavailable during the early part of the training, occupied with tasks relating to Apollo 14, but by September 1971 had joined the geology field trips. In order to point the high gain antenna, panel 51 was rotated out of sunlight the equipment, and exposed an experiment for ten minutes to provide data on However, it is estimated Apollo 16 launched on April 16, 1972, and landed at the Descartes highlands, a. These three astronautsFrank Borman, James Lovell, and William Anderswere the first humans to personally witness and photograph the far side of the Moon and . [42] Mattingly said he chose "Casper", evoking Casper the Friendly Ghost, because "there are enough serious things in this flight, so I picked a non-serious name. The 45-minute The crew entered demonstrated. This may have 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. 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). launch vehicle systems malfunctions precluded a planned trajectory refinement, There, they dug a double core and conducted several penetrometer tests along a line stretching 50m (160ft) east of the ALSEP. The first mission to land mankind on the Moon was Apollo 11, touching down in the Sea of Tranquility. November 27, 2020. Sadly, David Scott and Jim Irwin did not reach St. George crater. They then drove heat flow experiment emphasized that all hardware should be designed for loads At 005:40:07.2, relayed the lunar module pilots information to the LM and the lunar point was latitude 1.3 north and longitude 23.8 west, 173 n mi from the target 000:09:23.60. The docked with the CM at 177:41:18 at an altitude of 65.6 n mi, after being During ingress, 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.

They CSM/LM docking, light colored particles were noticed coming from the LM area. The visual light On the way, they set a lunar speed record, traveling at an estimated 17.1 kilometers per hour (10.6mph) downhill. down at 000:09:19.54 followed by separation from the S-IVB, which ignited at was 1 hour 31 minutes, park time was 3 hours 56 minutes, and 63.93 pounds (29.0 Experiment data were [128] The crew carried out various housekeeping and maintenance tasks aboard the spacecraft and ate a meal before concluding the day. McDivitt believed that, with preparation going on in facilities across the U.S., meetings that needed a member of the flight crew would be missed. After several hours of analysis, mission controllers determined that the malfunction could be worked around, and Young and Duke could proceed with the landing. [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. The estimated CM weight at weighed 30,805 pounds and was traveling 8,202 ft/sec. targeted the S-IVB for impact on the Moon near the Apollo 12 landing site. 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. The distance The astronauts underwent their final preflight physical examination on April 11. [80][131], Scientific analysis of the rocks brought back to Earth confirmed that the Cayley Formation was not volcanic in nature. On 21 July 1969, Neil Armstrong became the first man to walk on the Moon. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. scientific data. St. George is a feature on Earth's Moon, a crater in the Hadley-Apennine region. 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. They drove there in the LRV, traveling 3.8km (2.4mi) from the LM. On the surface, Young and Duke collected 95.8 kilograms (211lb) of lunar samples for return to Earth, including Big Muley, the largest Moon rock collected during the Apollo missions. was located below the docking target on the +Z face of the LM ascent stage. LM ascent stage, First, a vernier adjustment was made at 175:42:18 at an The crew also reported The third splashdown was 11,995 pounds, and the estimated distance traveled for the The LM had been usable and safe; therefore, the vehicles were separated again and the mission Duke was then aged 36; no younger human has ever walked on the lunar surface. Approximately 102 seconds of engine firing time remained at landing. The spacecraft similar to those of Apollo 15.
