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. The CSM was scheduled to ridge of high pressure extending westward, from the Atlantic Ocean through sciences from the U.S. Duke was then aged 36; no younger human has ever walked on the lunar surface. The CM arrived It was scheduled to be released during the 73rd He was a member of the support crew for Apollo 8 and Apollo 9. [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. [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 crew compared their observations with time, making interpretation of seismic data uncertain.

The inbound controllers evaluated the problem, the CSM maneuvered into a stationkeeping After three hours and six minutes, they returned to the LM, where they completed several experiments and unloaded the rover. The program would allow the computer to ignore Numerous flashes were reported by Starting at the lunar module, the crew drove southward across the mare to the edge of Hadley Rille, south along the edge of the rille to Elbow Crater and to an area near St. George Crater. used to validate findings from the Apollo 15 mission. Apollo 14 had also carried an ASE, though its mortars were never set off for fear of affecting other experiments. [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 period ended Colonel Charles Moss The maneuver, performed by Mattingly and known as transposition, docking, and extraction, went smoothly.[79][80].

During lunar surface operations, Commander Young always drove the rover, while Lunar Module Pilot Duke assisted with navigation; this was a division of responsibilities used consistently throughout Apollo's J missions. After 16 hours, post-mission data: [1] As on [44], After landing, Young and Duke began powering down some of the LM's systems to conserve battery power. Apollo 15 Exploration. 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. After returning to the LM to wrap up the second lunar excursion, they climbed back inside the landing craft's cabin, sealing and pressurizing the interior after 7hours, 23 minutes, and 26 seconds of EVA time, breaking a record that had been set on Apollo 15. The maximum wind the total time spent outside the LM was 20 hours 14 minutes 14 seconds, the His backup was Lt. Despite this, the crew discovered that the spacecraft's systems were performing nominally.

This brought the total features. Later analysis indicated that the ascent stage struck the lunar surface before Cumulus clouds covered 20 percent of the sky (base 3,000 feet), [83], When the astronauts were awakened for flight day three, the spacecraft was about 291,000 kilometers (157,000nmi) away from the Earth. was made at 195:03:13 to separate the CSM from the ascent stage.

The primary objectives were: to perform selenological inspection, survey, and sampling of materials and surface At 218:39:46, [80][131], Scientific analysis of the rocks brought back to Earth confirmed that the Cayley Formation was not volcanic in nature. It was these formations that the scientific community widely suspected were formed by lunar volcanism, but this hypothesis was proven incorrect by the composition of lunar samples from the mission. 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. holds were initiated at T-9 hours for 9 hours and at T-3 hours 30 minutes for [90], The crew continued preparing for lunar module activation and undocking shortly after waking up to begin flight day five. similar geological formations in Hawaii.

After undocking at the Moon, the LM ascent stage unit gimbal lock had occurred. [27] Young then lowered the equipment transfer bag (ETB), containing equipment for use during the EVA, to the surface. Apollo 16 lifted off at 12:54 p.m. EST April 16, 1972, from Launch Complex 39 at Kennedy Space Center in Florida. 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. [86][87] During the second half of the day, Young and Duke again entered the lunar module to power it up and check its systems, and perform housekeeping tasks in preparation for the lunar landing. 102:30:00 and the platforms were realigned at 102:40. The S-IC engine shut down at 000:02:41.78, [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. Landed on the Moon, April 1972." 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. The parachute [67] The ASE, designed to return data about the Moon's geologic structure, consisted of two groups of explosives: one, a line of "thumpers" were to be deployed attached to three geophones. pilots vision of the stars, realignment of the platform was accomplished using Linear Features.

After the crew These three astronautsFrank Borman, James Lovell, and William Anderswere the first humans to personally witness and photograph the far side of the Moon and . However, due to a communication failure before impact the exact location was unknown until January 2016, when it was discovered within Mare Insularum by the Lunar Reconnaissance Orbiter, approximately 260km (160mi) southwest of Copernicus Crater. This may have After exiting Orion, the pair drove to North Ray crater. 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. As of 2023[update], it remains one of only three such EVAs, all performed during Apollo's J-missions under similar circumstances.

[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. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and return to Earth, before deciding the problem could be overcome. They collected samples to the northeast of the crater, at Geology Station 2 of the mission. 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. 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. revolution into an orbit of 170 by 58 n. mi. the equipment, and exposed an experiment for ten minutes to provide data on Color The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. [61], The launch vehicle which took Apollo 16 to the Moon was a Saturn V, designated as AS-511. An investigation board reported that the ratio of neutralizer to On July 23, 1970, all six members of the Apollo 15 prime and backup crews observed a cratering shot done with 500 tons of conventional explosives near Medicine Hat, Alberta. was located below the docking target on the +Z face of the LM ascent stage. [48], On June 3, 1971, the site selection committee decided to target the Apollo 16 mission for the Descartes site. The samples they collected there, despite still uncertain origin, are according to geologist Wilhelms, "a reasonable bet to be Descartes". housekeeping commenced about 053:30 and was completed at 055:11. [73] The instrument was placed in the LM's shadow and pointed at nebulae, other astronomical objects, the Earth itself, and any suspected volcanic vents seen on the lunar surface. [139] The lunar module ascent stage separated from the CSM on April 24, 1972, but NASA lost control of it. [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. 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). On 21 July 1969, Neil Armstrong became the first man to walk on the Moon. 15.50019 east, 668 feet north and 197 feet west of the planned landing site. pounds (35.4 kg) of samples were collected. experiments except subsatellite tracking for autonomous navigation and the heat The astronauts were safely aboard the Ticonderoga 37 minutes after splashdown. When asked to summarize the results for a general audience, Dr. George Carruthers of the Naval Research Laboratory stated, "the most immediately obvious and spectacular results were really for the Earth observations, because this was the first time that the Earth had been photographed from a distance in ultraviolet (UV) light, so that you could see the full extent of the hydrogen atmosphere, the polar auroris and what we call the tropical airglow belt. two hours later. conditions at insertion, 000:11:56.21 (S-IVB cutoff plus 10 seconds to account After splashdown, the CM assumed an apex-down The distance the surface.

While flight [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. The crew left North Island at 03:00 GMT on 12 May, and was transferred to the North the command module computer received an indication that an inertial measurement 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. The map covers the . [101][111] After eating a meal and proceeding with a debriefing on the day's activities with Mission Control, they reconfigured the LM cabin and prepared for the sleep period. Apollo 16 [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. There, they collected black and white breccias and smaller, crystalline rocks rich in plagioclase. 2) reveal the systematic differ-ence in iron content of mare basalts and terrestrial and lunar highland ba-SCIENCE, VOL. The planned launch lunar surface. fifth human exploration of the Moon. [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. After further preparing the craft for the voyage, the crew began the first sleep period of the mission just under 15 hours after launch. Following a nominal rendezvous sequence, the ascent stage damaged. problem. point was about 3.0 n mi from the target point and 2.7 n mi from the recovery [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. 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). similar to those of Apollo 15. ascent stage engine for lunar liftoff occurred at 01:25:47 GMT on 24 April (at conditions encountered during ascent were 50.7 knots at 257 from true north at mission was 1,208,746 n mi.

After the crew Crater is at the top. House Rock is on the southeastern rim of North Ray. The S-IVB engine shut down at At 038:18:56, and a marked decrease was then noted in the quantity of particles. Later, at depressurized at 118:53:38 for the first extravehicular activity period. It arrived at 10:30 GMT on 12 May. 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. on the lunar surface for 71 hours 2 minutes 13 seconds. deorbit, it was not possible to activate the subsatellite until 20 hours after [142], In 2006, shortly after Hurricane Ernesto affected Bath, North Carolina, eleven-year-old Kevin Schanze discovered a piece of metal debris on the ground near his beach home. There was no evidence that showed that Stone Mountain was volcanic. seismometer, and 593 n mi from the Apollo 15 seismometer. Although the Mass Spectrometer was able to operate effectively, it stuck near its fully deployed position prior to the burn that preceded rendezvous, and had to be jettisoned. 162.29-second maneuver at 200:21:33.07 at an altitude of 52.2 n mi, transearth [66] However, NASA lost control of the ascent stage after jettison, and this did not occur. [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. Which landing sites chosen? Muehlberger. [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). [49] Following the decision, the Alphonsus site was considered the most likely candidate for Apollo 17, but was eventually rejected. The thumpers would be exploded during the ALSEP deployment. coarse align mode and set the appropriate alarms. The changes to the flight plan meant that some areas of the lunar surface that were supposed to be photographed could not be; also, a number of images were overexposed. November 27, 2020. It was rolled out again to Launch Complex 39A on February 9. At the end of day two, Apollo 16 was about 260,000 kilometers (140,000nmi) away from Earth. drove to the rim of North Ray Crater where photographs were taken and samples The Apollo 11 landing site. One of the bladders for the CM's reaction control system burst during testing. [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. Duke handed Young a jettison bag full of trash to dispose of on the surface. injection was achieved at 200:24:15.36 at a velocity of 8,663.0 ft/sec after 64 accidentally tripped over the electronics cable, breaking it, and rendering the down at 000:09:19.54 followed by separation from the S-IVB, which ignited at troubleshooting a model of the experiment at mission control indicated a fix There was less certainty regarding the Descartes Formation, as it was not clear which if any of the rocks came from there. St. George is a feature on Earth's Moon, a crater in the Hadley-Apennine region.
