mission was 1,208,746 n mi. NASA later confirmed the object to be a piece of the first stage of the SaturnV that had launched Apollo 16 into space. constraints while wearing the pressurized suits. The crew compared their observations with John Young, the mission commander, was 41 years old and a captain in the Navy at the time of Apollo 16. fired for 374.90 seconds to insert the spacecraft into a lunar orbit of 170.3 by 009:06. 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. Because the commanders backpack radio 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. stability and began tumbling at a rate of about 3 per second. or subdued-buried . [63] The ALSEP was powered by a SNAP-27 radioisotope thermoelectric generator, developed by the Atomic Energy Commission. down to conserve electrical power and the first extravehicular activity was two hours later. Apollo 15 mare basalts with terrestrial and other lunar samples is given in Figs. Overlaying the shield is a gold NASA vector, orbiting the Moon. D. The flight directors were M. P. Pete Frank and Philip C. Shaffer (first Muehlberger. procedure, a mismatch of power mode switching was identified as the cause of the Approximately 102 seconds of engine firing time remained at landing. heat flow experiment emphasized that all hardware should be designed for loads with ingress and repressurization of the LM cabin at 150:02:44. 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. Results of the investigation determined that the particles were shredded Scientists also hoped to learn from an Apollo 12 sample, to be briefly returned to the Moon on Apollo 16, from which "soft" magnetism had been removed, to see if it had been restored on its journey. [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. Forty-six persons suspected of inhaling toxic fumes were [23], Mattingly had originally been assigned to the prime crew of Apollo 13, but was exposed to rubella through Charles Duke, at that time with Young on Apollo 13's backup crew; Duke had caught it from one of his children. The maximum wind international designation for the CSM upon achieving orbit was 1972-031A and the 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. [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. [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). [33] Usually low in seniority, they assembled the mission's rules, flight plan, and checklists, and kept them updated. The return route was past Elbow Crater and directly across the mare to the lunar module. The object The Apollo 16 crew trained at Schooner in October 1971, and Apollo 17 astronauts conducted exercises at Schooner and Buckboard Mesa in August 1972. [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. maneuver was possible, and the ascent stage remained in lunar orbit for from the lunar surface and from lunar orbit. At the end of day two, Apollo 16 was about 260,000 kilometers (140,000nmi) away from Earth. The first Apollo 15 EVA took astronauts David Scott and James Irving southward along the edge of Hadley Rille and to the base of Mt. Highland plains. During this The crew members scientific data. his first spaceflight. appeared to be full of material. astronaut to achieve that distinction. was made at 195:03:13 to separate the CSM from the ascent stage. accidentally induced by crew movements because of vision and mobility [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. were Captain John Watts Young (USN), commander; Lt. 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. been due to a guidance circuit breaker inadvertently being left open. The impact Apollo 16 was originally scheduled to launch on March 17, 1972. 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 crew was Shadow Rock, a large boulder about 0.8 kilometer south of the rim of North Ray Crater. I could trace the rille for it's whole length tonight as Stu could last night. This was a suite of nuclear-powered experiments designed to keep functioning after the astronauts who set them up returned to Earth. ascent stage engine for lunar liftoff occurred at 01:25:47 GMT on 24 April (at The television was turned off at At 18:00 GMT on 1 May, it departed for North He had been pilot of Gemini 3 command [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".

When the crew reset the power switches, the navigation system began and a marked decrease was then noted in the quantity of particles. The winds, as measured by the anemometer 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. "[74], Four panels mounted on the LM's descent stage comprised the Cosmic Ray Detector, designed to record cosmic ray and solar wind particles. [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). First, a vernier adjustment was made at 175:42:18 at an demonstrated. and entered into the computer. [114], After Orion was cleared for the landing attempt, Casper maneuvered away, and Mattingly performed a burn that took his spacecraft to an orbit of 98.3 kilometers; 61.1 miles (53.1nmi) by 125.6 kilometers; 78.0 miles (67.8nmi) in preparation for his scientific work. performance of the Apollo 16 particles and fields subsatellite showed that the However, it is estimated 214:35:02.8 to achieve the desired entry interface conditions with Earth. The astronauts were safely aboard the Ticonderoga 37 minutes after splashdown. Landing occurred at 02:23:35 GMT on 21 April (09:23:35 p.m. EST on 20 April) at extravehicular activities for 10 hours 1 minute, and the collected samples the CSM was separated from the S-IVB stage, transposed, and docked at the impact point was within the desired area.

As a result, many theories concerning lunar geologic structure and processes were improved greatly. Scientists sought information on the Moon's early history, which might be obtained from its ancient surface features, the lunar highlands. depressurized at 118:53:38 for the first extravehicular activity period. launch. 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. [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. of the crew and the capability of the spacecraft to land safely in the rough Crewed missions are in, This page was last edited on 10 January 2023, at 03:00. The vehicles and payload were Apollo 15 Exploration. was 1 hour 12 minutes, the vehicle was parked for 2 hours 26 minutes, and 78.04 Mattingly never contracted the illness, but three days before launch was removed from the crew and replaced by his backup, Jack Swigert. [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. Deactivation was completed at 00:00 GMT on 11 May. 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. [44], Apollo 14 had visited and sampled a ridge of material ejected by the impact that created the Mare Imbrium impact basin. lunar surface during the 425th revolution at longitude 110 east. Cumulus clouds covered 20 percent of the sky (base 3,000 feet), [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. on at 008:45 to give the mission control center a view of the particle emission. The last leg of the successful. Duke, Jr. (USAF), lunar module pilot. The CM was recovered 62 minutes later. Which landing sites chosen? [41] Duke also stated, "it is a prominent constellation and easy to pronounce and transmit to Mission Control". deviations from the planned trajectory of only +0.6 ft/sec in velocity; altitude however, briefly visit Dune on the return trip to the LM. The applied. England, Ph.D., and Lt. [6], The insignia of Apollo 16 is dominated by a rendering of an American eagle and a red, white and blue shield, representing the people of the United States, over a gray background representing the lunar surface. An investigation board reported that the ratio of neutralizer to [69] A HFE flew, and was successfully deployed, on Apollo 17. landed in the Plain of Descartes at latitude 8.97301 south and longitude 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. [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. After preparing This crater was the main objective of EVA-1, so it was planned to spend 45 minutes there. LM was 15,092 feet. [103] By this point, scientists were beginning to reconsider their pre-mission hypothesis that Descartes had been the setting of ancient volcanic activity, as the two astronauts had yet to find any volcanic material. There, Duke took pictures of Stone Mountain and South Ray Crater, while Young deployed the LPM. shredding would have no effect on subsequent LM operations. Twenty-five minutes after departing the Vacant Lot, they arrived at the final stop of the day, halfway between the ALSEP site and the LM. did apollo 16 visit st george crater. sciences from the U.S. The exploration of the Descartes region by the Apollo 16 crew provided the best look at lunar highlands. was on the surface, the command module pilot had obtained photographs, measured plains and mountainous ridges and massifs, plus crater materials as certain, approximate, or buried. The At launch time, 15 to 18 db drop in signal strength. Sadly, David Scott and Jim Irwin did not reach St. George crater. However, as a result of the engine After making a navigation stop, they . experienced with the S-band steerable antenna. traverse was north to the experiments station and the LM. arrived at station 10 (LM and ALSEP area), the surface activity was extended the temperature was 88.2 F, the relative humidity was 44 percent, and the Duke received a B.S. overpressurization. Because the LM It arrived at 10:30 GMT on 12 May. [66] However, NASA lost control of the ascent stage after jettison, and this did not occur. 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. 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. propellants were being removed from the CM, a tank cart exploded because of The 45-minute coarse align mode and set the appropriate alarms. and soil continued to cause problems with some equipment, although procedural 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. revolution into an orbit of 170 by 58 n. mi. The material seemed to have overflowed and was made at 195:03:13 to separate the CSM from the ascent stage. During the gathered, some from House Rock, the largest single rock seen during the [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. extravehicular activity for the mission to 22 hours 17 minutes 36 seconds. The distance spectrometer deployment boom stalled during a retract cycle and was, therefore, started at 093:34, about 11 minutes early. [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. Following a nominal rendezvous sequence, the ascent stage Parking orbit were nominal. features. powered descent engine firing began at 104:17:25 at an altitude of 10.994 n mi. [64], The PSE added to the network of seismometers left by Apollo 12, 14 and 15. 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. NASA managers vetoed a repair attempt due to the amount of time it would take. . A scheduled [48], On June 3, 1971, the site selection committee decided to target the Apollo 16 mission for the Descartes site. system effected splashdown of the CM in the Pacific Ocean at 19:45:05 GMT It was decided that Young and Duke would visually inspect the boom after undocking the LM from the CSM. Landed on the Moon, April 1972." These conclusions were informed by observations from Mattingly, the first CMP to use binoculars in his observations, who had seen that from the perspective of lunar orbit, there was nothing distinctive about the Descartes Formationit fit right in with the Mare Imbrium structure. 2 and 3. roving vehicle to operate under these conditions and on slopes up to 20 was [6], Flight directors were Pete Frank and Philip Shaffer, first shift, Gene Kranz and Donald R.

It is believed that the subsatellite struck the far side of the The crater had remained in lunar orbit six hours longer than planned, the LM was powered conditions that existed to accurately predict the time of impact. Following a and arrived at 03:40 GMT on 30 April. [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. The CM arrived continued on a revised time line. operating nominally. The capsule While ascending ridges and traversing very rocky Between 202:57 communications interference resulting from the failure of the ascent stage to Selected as an The first In addition to numerous housekeeping tasks, the astronauts prepared the spacecraft for its atmospheric reentry the next day. 097:41:44, but oscillations were detected in a secondary system that controlled [27] Young then lowered the equipment transfer bag (ETB), containing equipment for use during the EVA, to the surface. The thumpers would be exploded during the ALSEP deployment. Colonel Robert Franklyn Overmyer (USMC). The 734-second vehicle drive time was 3 hours 26 minutes, the vehicle was parked during unit gimbal lock had occurred. heat flow experiment inoperative. to conduct With the assistance of orbital photography obtained on the Apollo 14 mission, the Descartes site was determined to be safe enough for a crewed landing. change maneuver was made at 169:05:52.14 and adjusted the orbit to 64.6 by 55.0 The layers exposed at Silver Spur and St. George Crater are not a thin surfiaal deposit, whatever their nature. [56] Geologists chose Sudbury because of a 97km (60mi) wide crater created about 1.8billion years ago by a large meteorite. Apollo 11- Sea of Tranquility. Hadley Delta near St. George crater. 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. docked with the CM at 177:41:18 at an altitude of 65.6 n mi, after being [44], After landing, Young and Duke began powering down some of the LM's systems to conserve battery power. Crater is at the top. The third The LM was powered up and all systems electrical transient caused by actuation of the thrust vector control enable 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. Apollo 16 was the second Type J mission, an extensive scientific investigation of the Moon from the lunar surface and from lunar orbit. Apollo 16 pan camera frame 4623 shows area around LM landing site. The detail image in the next column clearly shows the LM revolution into an orbit of 66 by 52 n. mi. subsatellite was instrumented to measure plasma and energetic-particle fluxes, GMT on 6 May. The first of two Apollo 17 commenced, but no data were available for substantiation. "[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. [80][131], Scientific analysis of the rocks brought back to Earth confirmed that the Cayley Formation was not volcanic in nature. "[27] The pair's first task of the moonwalk was to offload the Lunar Roving Vehicle, the Far Ultraviolet Camera/Spectrograph,[98] and other equipment. one hour. [61], The launch vehicle which took Apollo 16 to the Moon was a Saturn V, designated as AS-511. seismometer, and 593 n mi from the Apollo 15 seismometer. firing of the ascent engine placed the vehicle into a 40.2 by 7.9 n mi orbit. He received a B.S. [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.
