After decades of uncertainty, the Apollo 16 S-IVB impact site on the lunar surface has been identified. S-IVBs were portions of the Saturn V rockets that brought astronauts to the moon. The site was identified in imagery from the high-resolution LROC Narrow Angle Camera aboard NASA's Lunar Reconnaissance Orbiter. Beginning with Apollo 13, the S-IVB rocket stages were deliberately impacted on the lunar surface after they were used. Seismometers placed on the moon by earlier Apollo astronauts measured the energy of these impacts to shed light on the internal lunar structure. Locations of the craters that the boosters left behind were estimated from tracking data collected just prior to the impacts. Earlier in the LRO mission, the Apollo 13, 14, 15 and 17 impact sites were successfully identified, but Apollo 16's remained elusive. In the case of Apollo 16, radio contact with the booster was lost before the impact, so the location was only poorly known. Positive identification of the Apollo 16 S-IVB site took more time than the other four impact craters because the location ended up differing by about 30 km (about 19 miles) from the Apollo-era tracking estimate. (For comparison, the other four S-IVB craters were all within 7 km -- about four miles -- of their estimated locations.) Apollo 16's S-IVB stage is on Mare Insularum, about 160 miles southwest of Copernicus Crater (more precisely: 1.921 degrees north, 335.377 degrees east, minus 1,104 meters elevation).

Nearer the horizon is Mare Nectaris (Sea of Nectar) with craters Goclenius and Gutenberg in between. Goclenius is located at approximately 10 degrees south latitude and 45 degrees east longitude.

AS16-118-18873 (16 April 1972) --- A good view of Earth photographed shortly after trans-lunar injection of April 16, 1972. Although there is much cloud cover (over Canada and the oceans), the United States in large part, most of Mexico and some parts of Central America are clearly visible. Note Lake Michigan and Lake Superior, also note the Bahama Banks at upper right part of the sphere. A large part of the Rocky Mountain Range is also visible. Just beginning man's fifth lunar landing mission were astronauts John W. Young, commander; Thomas K. Mattingly II, command module pilot; and Charles M. Duke Jr., lunar module pilot. While astronauts Young and Duke descended in the Lunar Module (LM) to explore the moon, astronaut Mattingly remained with the Command and Service Modules (CSM) in lunar orbit.

AS16-116-18599 (21 April 1972) --- A close-up view of Buster Crater, which was visited by the two moon-exploring crew men of the Apollo 16 lunar landing mission, during the first extravehicular activity (EVA), April 21, 1972. Astronaut Charles M. Duke Jr. said the crater appeared to be larger than 50 meters, and he called it a very spectacular crater. This was the second stop for astronauts John W. Young and Duke on the mission's first EVA. Young exposed this view with his 70mm Hasselblad camera. While astronauts Young, commander; and Duke, lunar module pilot; descended in the Apollo 16 Lunar Module (LM) "Orion" to explore the Descartes highlands landing site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

AS16-107-17573 (22 April 1972) --- A close-up view of a block (about 1/2 meter long) found by the two moon-exploring crewmembers of the Apollo 16 lunar landing mission. The block had been rolled over only moments earlier during this Apollo 16 second extravehicular activity (EVA) near South Ray Crater. Astronaut John W. Young, commander, said at the post-mission press conference, "The block has been sitting there evidently since South Ray Crater was formed." While astronauts Young and Charles M. Duke Jr., lunar module pilot; descended in the Apollo 16 Lunar Module (LM) "Orion" to explore the Descartes highlands landing site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

Luna 16 was the first robotic mission to land on the Moon on basaltic plains of Mare Fecunditatis and return a sample to the Earth. It was launched by the Soviet Union on 12 September 1970. This image was taken by NASA Lunar Reconnaissance Orbiter.

This is the Apollo 16 lunar landing mission crew portrait. Pictured from left to right are: Thomas K. Mattingly II, Command Module pilot; John W. Young, Mission Commander; and Charles M. Duke Jr., Lunar Module pilot. Launched from the Kennedy Space Center on April 16, 1972, Apollo 16 spent three days on Earth's Moon. The first study of the highlands area, the landing site for Apollo 16 was the Descartes Highlands. The fifth lunar landing mission out of six, Apollo 16 was famous for deploying and using an ultraviolet telescope as the first lunar observatory. The telescope photographed ultraviolet light emitted by Earth and other celestial objects. The Lunar Roving Vehicle, developed by the Marshall Space Flight Center, was also used for collecting rocks and data on the mysterious lunar highlands. In this photo, astronaut John W. Young photographs Charles M. Duke, Jr. collecting rock samples at the Descartes landing site. Duke stands by Plum Crater while the Lunar Roving Vehicle waits parked in the background. High above, Thomas K. Mattingly orbits in the Command Module. The mission ended April 27, 1972 as the crew splashed down into the Pacific Ocean.

A closeup view or "mug shot" of Apollo 16 lunar sample no. 68815, a dislodged fragment from a parent boulder roughly four feet high and five feet long encountered at Station 8. The crew tried in vain to overturn the parent boulder. A fillet-soil sample was taken close to the boulder, allowing for study of the type and rate of erosion acting on lunar rocks. The fragment itself is very hard, has many veticles and a variety of inclusions. In addition, numerous metallic particles were observed in the black matrix.

AS16-120-19187 (19 April 1972) --- Apollo 16 astronauts captured this Earth rise scene with a handheld Hasselblad camera during the second revolution of the moon. Identifiable craters seen on the moon include Saha, Wyld, and Saenger. Much of the terrain seen here is never visible from Earth, as the Command Module (CM) was just passing onto what is known as the dark side or far side of the moon. Crewmen aboard the CM at the time the photo was made were astronauts John W. Young, Thomas K. Mattingly II and Charles M. Duke Jr. Mattingly remained later with the CM in lunar orbit while Young and Duke descended in the lunar module (LM) to explore the surface of the moon.

AS16-121-19407 (April 1972) --- An oblique view of a rim of Guyot Crater on the lunar farside, as photographed from the Apollo 16 spacecraft in lunar orbit. The coordinates of the center of Guyot Crater are 116.5 degrees east longitude and 10.5 degrees north latitude. Note the black coloration which appears to be lava flow down the side of the crater rim. While astronauts John W. Young, commander; and Charles M. Duke Jr., lunar module pilot; descended in the Apollo 16 Lunar Module (LM) "Orion" to explore the Descartes highlands site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

This view of the back side of the Moon was captured by the Apollo 16 mission crew. The sixth manned lunar landing mission, the Apollo 16 (SA-511), carrying three astronauts: Mission Commander John W. Young, Command Module pilot Thomas K. Mattingly II, and Lunar Module pilot Charles M. Duke, lifted off on April 16, 1972. The Apollo 16 continued the broad-scale geological, geochemical, and geophysical mapping of the Moon’s crust, begun by the Apollo 15, from lunar orbit. This mission marked the first use of the Moon as an astronomical observatory by using the ultraviolet camera/spectrograph which photographed ultraviolet light emitted by Earth and other celestial objects. The Lunar Roving Vehicle, developed by the Marshall Space Flight Center, was also used. The mission ended on April 27, 1972.

The Apollo 16 crew patch is dominated by an eagle perched atop a red, white, and blue shield superimposed on a lunar surface scene. Similar to that on the NASA agency shield and insignia, there is a gold symbol of flight outlined in blue across the face of the shield. The border surrounding the shield is a circle of 16 stars completed by the the crew’s surnames at the bottom. The patch was designed from ideas submitted by the Apollo 16 3-man crew: John W. Young, Mission Commander: Thomas K. Mattingly, Command Module pilot; and Charles M. Duke, Lunar Module pilot. (Note: This is the official Apollo 16 emblem, a property of the United States government.

AS16-113-18334 (21 April 1972) --- View of the Lunar Module (LM) "Orion" parked on the lunar surface. During their post mission press conference, the Apollo 16 crewmembers called attention to the steerable S-band antenna, which was "frozen" in a yaw axis during much of the flight. This view of the LM was photographed by astronaut Charles M. Duke Jr., the lunar module pilot, during the mission's first extravehicular activity (EVA). Astronauts John W. Young, commander, and Duke had earlier descended in the LM to explore the Descartes region of the moon, while astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

S71-44150 (February 1971) --- A vertical view of the Apollo 16 landing site located in the Descartes area on the lunar nearside. The overlay indicates the location of the proposed touchdown point for the Apollo 16 Lunar Module (LM). Descartes is located west of the Sea of Nectar and southwest of the Sea of Tranquility. This photograph was taken with a 500mm lens camera from lunar orbit by the Apollo 16 crew. Astronauts John W. Young, commander; and Charles M. Duke Jr., lunar module pilot; descended in the Apollo 16 LM "Orion" to explore the Descartes highlands landing site on the moon. Astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

AS16-107-17561 (16-27 April 1972) --- One of the Apollo 16 astronauts scoops up lunar soil at the base of a small boulder at Station No. 9 during the second Apollo 16 extravehicular activity (EVA) at the Descartes landing site. Depressions to the right of the scoop were made when a surface sample was taken. This photograph was taken just before the boulder was rolled over. While astronauts John W. Young, commander; and Charles M. Duke Jr., lunar module pilot; descended in the Apollo 16 Lunar Module (LM) "Orion" to explore the Descartes highlands landing site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

AS16-119-19161 (16-27 April 1972) --- The prominent rille feature running through the area is Herigonius I. The coordinates for the center of the area pictured are 14.7 degrees south latitude and 36.4 degrees west longitude. The photo was taken by the Apollo 16 astronauts from the Command and Service Modules (CSM) in lunar orbit. While astronauts John W. Young and Charles M. Duke Jr. descended in the Lunar Module (LM) "Orion" to explore the Descartes highlands region of the moon, astronaut Thomas K. (Ken) Mattingly II, remained with the CSM "Casper" in lunar orbit.
