One anomaly, an auxiliary propulsion system leak on the S-IVB stage, produced an unpredictable thrust and prevented a final S-IVB targeting maneuver after separation from the CSM. Tracking of the S-IVB ended at 4:04 p.m. EST April 17, when the instrument unit's signal was lost. The stage hit the lunar surface at 4:02 p.m. April 19, 260 kilometers northeast of the target point. The impact was detected by the seismometers left on the moon by the Apollo 12, 14, and 15 missions.
Spacecraft operations were near normal during the coast to the moon. Unexplained light-colored particles from the LM were investigated and identified as shredded thermal paint. Other activities during the translunar coast included a cislunar navigation exercise, ultraviolet photography of the earth and moon, an electrophoresis demonstration, and an investigation of the visual light-flash phenomenon noted on previous flights. Astronaut Duke counted 70 white, instantaneous light flashes that left no after-glow.
Apollo 16 entered a lunar orbit of 314 by 107.7 kilometers at 3:22 p.m. April 19. After separation of LM-11 Orion from CSM 112 Casper, a CSM active rendezvous kept the two vehicles close together while an anomaly discovered on the service propulsion system was evaluated. Tests and analyses showed the redundant system to be still safe and usable if required. The vehicles were again separated and the mission continued on a revised timeline because of the 5 3/4-hour delay.
The lunar module landed with Duke and Young in the moon's Descartes region, about 230 meters northwest of the planned target area at 9:23 p.m. EST April 20. A sleep period was scheduled before EVA.
The first extravehicular activity began at 11:59 a.m. April 21, after the eight-hour rest period. Television coverage of surface activity was delayed until the lunar roving vehicle systems were activated, because the steerable antenna on the lunar module could not be used. The lunar surface experiments packages were deployed, but accidental breaking of the electronics cable rendered the heat flow experiment inoperable. After completing activities at the experiments site, the crew drove the lunar roving vehicle west to Flag Crater, where they performed the planned tasks. The inbound traverse route was just slightly south of the outbound route, and the next stop was Spook Crater. The crew then returned via the experiment station to the lunar module and deployed the solar wind composition experiment. The duration of the extravehicular activity was 7 hours 11 minutes. The distance traveled by the lunar roving vehicle was 4.2 kilometers. The crew collected 20 kilograms of samples.
The second extravehicular traverse, which began at 11:33 a.m. April 22, was south-southeast to a mare-sampling area near the Cinco Craters on Stone Mountain. The crew then drove in a northwesterly direction, making stops near Stubby and Wreck Craters. The last leg of the traverse was north to the experiments station and the lunar module. The second extravehicular activity lasted 7 hours 23 minutes. The distance traveled by the lunar roving vehicle was 11.1 kilometers.
Four stations were deleted from the third extravehicular traverse, which began 30 minutes early at 10:27 a.m. April 23 to allow extra time. The first stop was North Ray Crater, where "House Rock" on the rim of the crater was sampled. The crew then drove southeast to "Shadow Rock." The return route to the LM retraced the outbound route. The third extravehicular activity lasted 5 hours 40 minutes, and the lunar roving vehicle traveled 11.4 kilometers.
Lunar surface activities outside the LM totaled 20 hours 15 minutes for the mission. The total distance traveled in the lunar roving vehicle was 26.7 kilometers. The crew remained on the lunar surface 71 hours 14 minutes and collected 96.6 kilograms of lunar samples.
The SIM bay of the Apollo 16 scientific instrument module housed sensors and experiments to gather data on the moon's atmosphere and surface, as well as a subsatellite to be launched in lunar orbit. Gamma ray and mass spectrometer sensors extended on a boom when in use.
While the lunar module crew was on the surface, Mattingly, orbiting the moon in the CSM, was obtaining photographs, measuring physical properties of the moon and deep space, and making visual observations. Essentially the same complement of instruments was used to gather data as was used on the Apollo 15 mission, but different areas of the lunar surface were flown over and more comprehensive deep space measurements were made, providing scientific data that could be used to validate findings from Apollo 15 as well as add to the total store of knowledge of the moon and its atmosphere, the solar system, and galactic space.
The LM lifted off from the moon at 8:26 p.m. EST April 23, rendezvoused with the CSM, and docked with it in orbit. Young and Duke transferred to the CSM with samples, film, and equipment, and the LM was jettisoned the next day. LM attitude control was lost at jettison; therefore a deorbit maneuver was not possible and the LM remained in lunar orbit, with an estimated orbital lifetime of about one year.
The particles and fields subsatellite was launched into lunar orbit and normal system operation was noted. However, the spacecraft orbital shaping maneuver was not performed before ejection and the subsatellite was placed in a non-optimum orbit that resulted in a much shorter lifetime than the planned year. Loss of all subsatellite tracking and telemetry data on the 425th revolution (May 29) indicated that the subsatellite had hit the lunar surface.
The mass spectrometer deployment boom stalled during a retract cycle and was jettisoned before transearth injection. The second plane-change maneuver and some orbital science photography were deleted so that transearth injection could be performed about 24 hours earlier than originally planned.
Activities during the transearth coast phase of the mission included photography for a contamination study for the Skylab program and completion of the visual light-flash-phenomenon investigation that had been partially accomplished during translunar coast. A 1-hour 24-minute transearth extravehicular activity was conducted by command module pilot Mattingly to retrieve the film cassettes from the scientific instrument module cameras, inspect the equipment, and expose a microbial-response experiment to the space environment. Two midcourse corrections were made on the return flight to achieve the desired entry interface conditions.
Entry and landing were normal, completing a 265-hour 51-minute mission. The command module was viewed on television while dropping on the drogue parachutes, and continuous coverage was provided through crew recovery. Splashdown was at 2:44 p.m. EST April 27 in mid-Pacific, 5 kilometers from the recovery ship U.S.S. Ticonderoga. All primary mission objectives had been achieved (see Appendix 5).

Some recommendations were: The tasks being carried out by NASA to preserve and describe the samples, data, and photographs, and to make them available to the scientific community would need to continue for the next few years. The lunar sample curatorial facility at MSC was absolutely essential to lunar science objectives. The ALSEP network and the subsatellite should be operated continuously as long as significant new findings derived from their operation.

All launch vehicle systems performed normally in achieving an earth parking orbit of 170 by 168 kilometers. After checkout, insertion into a lunar trajectory was begun at 3:46 a.m.; translunar coast time was shortened to compensate for the launch delay. CSM 114 transposition, docking with LM-12, and LM ejection from the launch vehicle stage were normal. The S-IVB stage was maneuvered for lunar impact, striking the surface about 13.5 kilometers from the preplanned point at 3:27 p.m. EST December 10. The impact was recorded by the passive seismometers left on the moon by Apollo 12, 14, 15, and 16.
The crew performed a heat flow and convection demonstration and an Apollo light-flash experiment during the translunar coast. The scientific instrument module door on the SM was jettisoned at 10:17 a.m. EST December 10. The lunar orbit insertion maneuver was begun at 2:47 p.m. and the Apollo 17 spacecraft entered a lunar orbit of 315 by 97 kilometers. After separation of the LM Challenger from the CSM America and a readjustment of orbits, the LM began its powered descent and landed on the lunar surface in the Taurus-Littrow region at 2:55 p.m. EST on December 11, with Cernan and Schmitt.
The first EVA began about 4 hours later (6:55 p.m.). Offloading of the lunar roving vehicle and equipment proceeded as scheduled. The Apollo Lunar Surface Experiment Package was deployed approximately 185 meters west northwest of the Challenger. Astronaut Cernan drove the lunar roving vehicle to the experiments deployment site, drilled the heat flow and deep core holes, and emplaced the neutron probe experiment. Two geological units were sampled, two explosive packages deployed, and seven traverse gravimeter measurements were taken. During the 7-hour 12-minute EVA, 14 kilograms of samples were collected.
The second extravehicular activity began at 6:28 p.m. EST December 12. Because of geological interest, station stop times were modified. Orange soil was discovered and became the subject of considerable geological discussion. Five surface samples and a double core sample were taken in the area of the orange soil. Three explosive packages were deployed, seven traverse gravimeter measurements were taken, and observations were photographed. Samples collected totaled 34 kilograms during the 7 hours and 37 minutes of the second EVA.
The third and final EVA began at 5:26 p.m. EST December 13. Specific sampling objectives were accomplished. Samples - including blue-gray breccias, fine-grained vesicular basalts, crushed anorthositic rocks, and soils - weighed 66 kilograms. Nine traverse gravimeter measurements were made. The surface electrical properties experiment was terminated. Before reentering the LM, the crew selected a breccia rock to dedicate to the nations represented by students visiting the Mission Control Center. A plaque on the landing gear of the lunar module, commemorating all of the Apollo lunar landings, was then unveiled. After 7 hours 15 minutes, the last Apollo EVA on the lunar surface ended. Total time of the three EVAs was approximately 22 hours; the lunar roving vehicle was driven 35 kilometers, and about 115 kilograms of lunar sample material was acquired.
While Cernan and Schmitt were exploring the lunar surface, Evans was conducting numerous scientific activities in the CSM in lunar orbit. In addition to the panoramic camera, the mapping camera, and the laser altimeter, three new scientific instrument module experiments were included in the Apollo 17 orbital science equipment. An ultraviolet spectrometer measured lunar atmospheric density and composition; an infrared radiometer mapped the thermal characteristics of the moon; and a lunar sounder acquired data on the subsurface structure.
Challenger lifted off the moon at 5:55 p.m. EST December 14. Rendezvous with the orbiting CSM and docking were normal. The two astronauts transferred to the CM with samples and equipment and the LM ascent stage was jettisoned at 1:31 a.m. December 15. Its impact on the lunar surface about 1.6 kilometers from the planned target was recorded by four Apollo 17 geophones and the Apollo 12, 14, 15, and 16 seismometers emplaced on the surface. The seismic experiment explosive packages that had been deployed on the moon were detonated as planned and recorded on the geophones.
During the coast back to earth, Evans left the CSM at 3:27 p.m. EST December 17 for a 1-hour 7-minute inflight EVA and retrieved lunar sounder film and panoramic and mapping camera cassettes from the scientific instrument module bay. The crew conducted the Apollo light- flash experiment and operated the infrared radiometer and ultraviolet spectrometer.
Reentry, landing, and recovery were normal. The command module parachuted into the mid-Pacific at 2:25 p.m. EST December 19, 6.4 kilometers from the prime recovery ship, U.S.S. Ticonderoga. The crew was picked up by helicopter and was on board the U.S.S. Ticonderoga 52 minutes after the CM landed. All primary mission objectives had been achieved (see Appendix 5).

A letter Johnson had sent was read at the National Space Club's "Salute to Apollo" in Washington, D.C., in the evening. Johnson commended the "space pioneers who have made the Apollo miracle a living reality." He said: "It has been more, so much more than an amazing adventure into the unexplored and the unknown. The Apollo Program . . . will endure as a monument to many things, to the personal courage of some of the finest men our nation has ever produced, to the technological and managerial capability which is the genius of our system and to a successful cooperation among nations which has proved to us all what can be done when we work together with our eyes on a glorious goal.
"I rate Apollo as one of the real wonders of the world and I am proud that my country, through the exercise of great ability and daring leadership, has given it as a legacy to mankind."
