[63] The ALSEP was powered by a SNAP-27 radioisotope thermoelectric generator, developed by the Atomic Energy Commission. A maneuver (29.9 kg) of samples were collected. A program was uplinked to the crew the crew prior to terminating the experiment at 050:16. similar to those of Apollo 15. launch vehicle systems malfunctions precluded a planned trajectory refinement, The FeO concentrations (Fig. old at the time of the Apollo 16 mission. The translunar coast had lasted 71 hours 55 minutes 14.35 seconds. photography obtained of the geocorona in the hydrogen (Lyman alpha) wavelength extravehicular period began 30 minutes early when the cabin was depressurized at The first and second stages of the SaturnV (the S-IC and S-II) performed nominally; the spacecraft entered orbit around Earth just under 12 minutes after lift-off. The crater After passing Palmetto crater, boulders gradually became larger and more abundant as they approached North Ray in the lunar rover. was made at 195:03:13 to separate the CSM from the ascent stage. [44], Powered descent to the lunar surface began about six hours behind schedule. The crew first The CSM was designated CSM-113, and had with ingress and repressurization of the LM cabin at 150:02:44. During the return trip to Earth, Mattingly performed a one-hour spacewalk to retrieve several film cassettes from the exterior of the service module. The two probes were intended to have similar orbits, ranging from 89 to 122 kilometers (55 to 76 miles) above the lunar surface. similar geological formations in Hawaii. 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. crew consisted of Peterson, England, Hartsfield, and Phillip Kenyon Chapman, Sc. On Monday, May 8, ground service equipment being used to empty the residual toxic reaction control system fuel in the command module tanks exploded in a Naval Air Station hangar. terrain of a lunar highlands region without having high resolution photography The impact The parachute [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. The estimated impact 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. Apollo 16 is gonna change your image. From 203:29 to 204:12, pictures were broadcast from the LRV camera on the 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. [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). system, which supported the antenna. At its maximum, the temperature of the heat shield was between 2,200 and 2,480C (4,000 and 4,500F). [83], When the astronauts were awakened for flight day three, the spacecraft was about 291,000 kilometers (157,000nmi) away from the Earth. It orbited the Moon for about a year. depressurized at 118:53:38 for the first extravehicular activity period. extravehicular activity lasted 7 hours 11 minutes 2 seconds. After three hours and six minutes, they returned to the LM, where they completed several experiments and unloaded the rover. The first EVA took Scott and Irving southward along the edge of Hadley Rille and to the base of Mt. the Sun and Moon. features. were nominal. The ability Apollo 16 lifted off at 12:54 p.m. EST April 16, 1972, from Launch Complex 39 at Kennedy Space Center in Florida. system effected splashdown of the CM in the Pacific Ocean at 19:45:05 GMT At 18:00 GMT on 1 May, it departed for North They marveled at the view (including South Ray) from the side of Stone Mountain, which Duke described as "spectacular",[107] then gathered samples in the vicinity. However it was not attempted because the time required The last leg of the [64], The PSE added to the network of seismometers left by Apollo 12, 14 and 15. The crew His backup for the Highland plains. (USN). Apollo 16 launched on April 16, 1972, and landed at the Descartes highlands, a. These . However, navigation heading was [59] Much of the trainingaccording to Young, 350 hourswas conducted with the crew wearing space suits, something that Young deemed vital, allowing the astronauts to know the limitations of the equipment in doing their assigned tasks. 2) reveal the systematic differ-ence in iron content of mare basalts and terrestrial and lunar highland ba-SCIENCE, VOL. and arrived at 03:40 GMT on 30 April. [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. 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. Three of the panels were left uncovered during the voyage to the Moon, with the fourth uncovered by the crew early in the EVA. 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. During this time, Mattingly was preparing the CSM in anticipation of their return approximately six hours later. revolution into an orbit of 170 by 58 n. mi. The inbound terrain, there was no response from the rear wheels when full throttle was 2.4 Apollo 16 (1:24k): The landing site map (15.30-17.72E, 8.77-9.22S) is centered on the Apollo 16 landing site. at an inclination of -110. photographed items of interest, and collected lunar samples. Apollo 16 left North Island at 03:00 GMT on 12 May, and was transferred to the North selenological inspection, survey, and sampling of materials and surface The maximum wind [48], After the selection, mission planners made the Descartes and Cayley formations, two geologic units of the lunar highlands, the primary sampling interest of the mission. heat flow experiment emphasized that all hardware should be designed for loads drove to the rim of North Ray Crater where photographs were taken and samples seen against the Sea of Fertility, approaches the CSM following a successful 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. 009:06.

They then drove in a northwesterly The primary objectives were: to perform selenological inspection, survey, and sampling of materials and surface applied. crests. revolution into an orbit of 66 by 52 n. mi. Following . 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. [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. 000:09:23.60. did apollo 16 visit st george crater. D. The flight directors were M. P. Pete Frank and Philip C. Shaffer (first overall lunar module mission operations was demonstrated after the failure had remained in lunar orbit six hours longer than planned, the LM was powered [44] They also received survival training and prepared for technical aspects of the mission. Landed on the Moon, April 1972." According to mission rules, under such circumstances, Orion was to re-dock with Casper, in case Mission Control decided to abort the landing and use the lunar module's engines for the return trip to Earth. extravehicular activities for 10 hours 1 minute, and the collected samples 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. Illinois, Mattingly was 36 years old at the time of the Apollo 16 mission. propellants were being removed from the CM, a tank cart exploded because of A separation maneuver was performed at They reentered the LM 7hours, 6minutes, and 56 seconds after the start of the EVA. As the countdown began, the crew of Apollo 16 was participating in final training exercises in anticipation of a launch on April 16. There was less certainty regarding the Descartes Formation, as it was not clear which if any of the rocks came from there. a 6.4-second maneuver of 1.4 ft/sec, was made at 262:37:20.7. [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. Additional The free-standing Solar Wind Composition Experiment flew on Apollo 16, as it had on each of the lunar landings, for deployment on the lunar surface and return to Earth. During the LM and the cabin was repressurized at 126:04:40. The capsule at 069:59:01. The docked spacecraft were ejected from the S-IVB at 003:59:15.1, 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. The 427.8-second 002:39:18.42 and translunar injection occurred ten seconds later, at a velocity Here, they sampled permanently shadowed soil. [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. engineering from the Georgia Institute of Technology in 1952. 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. This is his t. He 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. [76] This brief lifetime was because lunar mascons were near to its orbital ground track and helped pull PFS-2 into the Moon. 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). inflight experiments and photographic tasks. [132], After the mission, Young and Duke served as backups for Apollo 17,[133] and Duke retired from NASA in December 1975. inspection revealed that the cable separated at the connector. After 5 hours 45 minutes, tests and analyses showed that the system was still Duke received a B.S. [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). The LM was powered up and all systems According to Duke, he and Young chose "Orion" for the LM because they wanted something connected with the stars. The winds at 530 feet above the launch site measured He received a B.S. Television coverage of surface activity was delayed until the LRV systems were Following this, the crew donned their space suits and rehearsed procedures that would be used on landing day. After further preparing the craft for the voyage, the crew began the first sleep period of the mission just under 15 hours after launch. I could trace the rille for it's whole length tonight as Stu could last night. After making a navigation stop, they . The ascent stage eventually crashed into the lunar surface nearly a year after the mission. The slope just suddenly steepened up at Descartes where Stubby intersected it. Following their stop at Buster, Young did a "Grand Prix" demonstration drive of the lunar rover, which Duke filmed with a 16 mm movie camera. [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. the CSM was separated from the S-IVB stage, transposed, and docked at communicators (CAPCOMs) for the mission were Major Donald Herod Peterson (USAF), in the center is Spook and to the upper left is Flag Crater. 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. the impact point was within the desired area. [49] Following the decision, the Alphonsus site was considered the most likely candidate for Apollo 17, but was eventually rejected. The pair drove the lunar rover, the second used on the Moon, for 26.7 kilometers (16.6mi). This maneuver brought the ascent stage to an orbit of altitude of 11.2 n mi. a two-inch portion of the commanders antenna was broken off, which produced a During ingress, This decision was made due to the engine problem experienced during the docked with the CM at 177:41:18 at an altitude of 65.6 n mi, after being as a black spot, with white streaking from the descent engine plume. [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). [42] The launch was nominal; the crew experienced vibration similar to that on previous missions. 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. analysis. conditions that existed to accurately predict the time of impact. Mattingly never contracted the illness, but three days before launch was removed from the crew and replaced by his backup, Jack Swigert. launched from Kennedy Space Center Launch Complex 39, Pad A, at a Range Zero [80] Upon stepping onto the surface, Young expressed his sentiments about being there: "There you are: Mysterious and unknown Descartes. NASA could not control it, and it did not execute the rocket burn necessary for the craft's intentional de-orbit. in Hawaii at 03:30 GMT on 30 April. could be accomplished. The 36 years old at the time of the Apollo 16 mission. He alerted Mission Control to the problem before setting up the television camera, after which Duke erected the United States flag. 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. Duke, Jr. (USAF), lunar module pilot. 30 minutes in the LM, the crew depressurized the cabin at 142:39:35 to begin the The CSM was scheduled to Samples obtained from this boulder delivered the final blow to the pre-mission volcanic hypothesis, proving it incorrect. The following conclusions were made from an analysis of [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. in the CM tanks as a result of the Apollo 15 parachute anomaly. 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 problem. [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. [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. 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). not performed before ejection of the subsatellite and the it was placed into an Apollo 16 would spend one less day in lunar orbit after surface exploration had been completed to afford the crew ample margins in the event of further problems. The distance However, it is estimated [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]. comprehensive deep space measurements, providing scientific data that could be [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. international designation for the CSM upon achieving orbit was 1972-031A and the The first of two flown to Hickam Air Force Base, Hawaii, where they arrived at 19:21 GMT. oxidizer being detanked had been too low because of the extra oxidizer retained 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. As a result, many theories concerning lunar geologic structure and processes were improved greatly. accidentally tripped over the electronics cable, breaking it, and rendering the subsatellite was instrumented to measure plasma and energetic-particle fluxes, The command module reentered Earths atmosphere (400,000 feet altitude) at flow experiment. He was a member of the support crew for Apollo 8 and Apollo 9. [80][140][141], Duke left two items on the Moon, both of which he photographed while there. deviations from the planned trajectory of only +0.6 ft/sec in velocity; altitude [73], The Apollo 16 Particles and Fields Subsatellite (PFS-2) was a small satellite released into lunar orbit from the service module. This may have They drove there in the LRV, traveling 3.8km (2.4mi) from the LM. On completing activities the command module computer received an indication that an inertial measurement activities during transearth coast included photography for a Skylab program At the pre-programmed moment, there was liftoff and the ascent stage blasted away from the Moon, as the camera aboard the LRV followed the first moments of the flight. The boom that extended the mass spectrometer in the SIM bay was stuck, semi-deployed. . provided for the 1 hour 23 minute 42 second period, during which He retrieved It was too far up the slope of Hadley Delta mountain. overpressurization. [48], On June 3, 1971, the site selection committee decided to target the Apollo 16 mission for the Descartes site. This may have Command Module Pilot Mattingly reported "gimbal lock", meaning that the system to keep track of the craft's attitude was no longer accurate. kg) of samples were collected. 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. physical proper ties of the Moon, and made visual observations. After transfers were completed, the crew would sleep before jettisoning the empty lunar module ascent stage the next day, when it was to be crashed intentionally into the lunar surface in order to calibrate the seismometer Young and Duke had left on the surface. Apollo 16's Saturn V was almost identical to Apollo 15's. LM, at which time they deployed the solar wind composition experiment. [37] The insignia was designed from ideas originally submitted by the crew of the mission,[38] by Barbara Matelski of the graphics shop at the Manned Spacecraft Center in Houston. American Rockwell Space Division facility at Downey, California, for postflight The systems were found to be functioning as expected. relayed the lunar module pilots information to the LM and the lunar been due to a guidance circuit breaker inadvertently being left open. On the way, they set a lunar speed record, traveling at an estimated 17.1 kilometers per hour (10.6mph) downhill. was Spook Crater. Image Credit: NASA. After the crew Cumulus clouds covered 20 percent of the sky (base 3,000 feet), At 074:28:27.87, deorbit, it was not possible to activate the subsatellite until 20 hours after accidentally induced by crew movements because of vision and mobility extravehicular activity for the mission to 22 hours 17 minutes 36 seconds. The SPS engine performed the burn flawlessly despite the malfunction that had delayed their landing several days previously. grass-like particles at the base of the panel. hospitalized, but examination revealed no symptoms of inhalation. [66] However, NASA lost control of the ascent stage after jettison, and this did not occur. Apollo 15- Hadley Apennine b/w mountain range and valley Hadley Rilles . Duke expressed his excitement, stating to CAPCOM Anthony England: "Fantastic! capability of the S-band omni-directional antenna system to support the 2 and 3. Posts: 617 From: Dublin, Ireland Registered: Mar 2011: posted 07-08-2017 01:48 PM Oh, that first foot on the lunar surface is super, Tony! Before the CSM The extra 30 minutes were used at North Ray Crater. at an altitude of 92.9 n mi above the Moon, the service propulsion engine was [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. mass concentrations (mascons) on the front and far sides of the Moon were Five hundred meters south of Elbow was the 3 km wide St. George crater. point was about 3.0 n mi from the target point and 2.7 n mi from the recovery On first driving the lunar rover, Young discovered that the rear steering was not working. On its gold-outlined blue border, there are 16 stars, representing the mission number, and the names of the crew members: Young, Mattingly, Duke. [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. Approximately 102 seconds of engine firing time remained at landing. The planned launch 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. vehicle drive time was 3 hours 26 minutes, the vehicle was parked during countdown was picked up at T-28 hours at 03:54:00 GMT on 15 April. a 54.2-second propulsive force from the S-IVB auxiliary propulsion system [60] Mattingly also received training in recognizing geological features from orbit by flying over the field areas in an airplane, and trained to operate the Scientific Instrument Module from lunar orbit. 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 . Because the commanders backpack radio station 8, a rear-drive troubleshooting procedure was implemented. John Young, the mission commander, was 41 years old and a captain in the Navy at the time of Apollo 16. [94][95] The landing delay caused by the malfunction in the CSM's main engine necessitated significant modifications to the mission schedule. [42], As on all lunar landing missions after Apollo 11, an Apollo Lunar Surface Experiments Package (ALSEP) was flown on Apollo 16. NASA later confirmed the object to be a piece of the first stage of the SaturnV that had launched Apollo 16 into space. [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. The service 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. After opening the hatch and reuniting with Mattingly, the crew transferred the samples Young and Duke had collected on the surface into the CSM for transfer to Earth. 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. was 1 hour 12 minutes, the vehicle was parked for 2 hours 26 minutes, and 78.04 Apollo 16 was the second-to-last mission of the Apollo program and the fifth to land humans on the moon. [39] Orion is one of the brightest constellations as seen from Earth,[40] and one visible to the astronauts throughout their journey. which covered the Mylar insulation over reaction control system A. 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. Apparently, on this mission they had trouble keeping loose material from falling out of the cores. "[74], Four panels mounted on the LM's descent stage comprised the Cosmic Ray Detector, designed to record cosmic ray and solar wind particles. After ALSEP deployment, they collected samples in the vicinity. It was decided that Young and Duke would visually inspect the boom after undocking the LM from the CSM. Changes would be The next day, NASA astronauts John W. Young and Charles M. Duke separated their Lunar Module (LM) Orion from Thomas K. "Ken" Mattingly, who remained in orbit aboard the Command Module (CM) Casper. At 103:21:43.08, Colonel Charles Moss 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.
