NASA’s Exploration Ground Systems’ Program Manager Shawn Quinn captured this image of the Hadley–Apennine region of the moon including the Apollo 15 landing site (very near the edge of the shadow of one of the lunar mountains in the area). Image is a crop of a full frame image. Apollo 11, 16 and 17 landing sites are also visible in this image. Hadley–Apennine is a region on the near side of Earth's Moon that served as the landing site for the American Apollo 15 mission, the fourth crewed landing on the Moon and the first of the "J-missions", in July 1971. The site is located on the eastern edge of Mare Imbrium on a lava plain known as Palus Putredinis. Hadley–Apennine is bordered by the Montes Apenninus (often referred to as "Apennine Front"), a mountain range, and Hadley Rille, a meandering channel, on the east and west, respectively.

AS15-90-12187 (31 July-2 Aug. 1971) --- This view, looking generally north, shows the tall Mount Hadley in the left background. The photograph was taken from the slope of Hadley Delta during Apollo 15 extravehicular activity (EVA). The crewmen of Apollo 15 noted the visible layering feature of the mountain. Note boulder in foreground. Mount Hadley rises approximately 14,765 feet (about 4,500 meters) above the plain.

AS15-91-12343 (26 July 1971) --- This view of Earth was photographed by the Apollo 15 crewmen as they sped toward the fourth lunar landing. The spacecraft was between 25,000 and 30,000 nautical miles from Earth when this photo was made. The United States (note Florida), Central America and part of Canada can be seen at the left side of the picture, with South America at lower center. Spain and the northwest part of Africa can be seen at right. The Bahamas Banks, unique geological feature, can be seen (different shade of blue) east of Florida. Also note large North Atlantic storm front moving over Greenland in upper center.

S71-58222 (31 July-2 Aug. 1971) --- During the lunar eclipse that occurred during the Apollo 15 lunar landing mission, astronaut Alfred M. Worden, command module pilot, used a 35mm Nikon camera to obtain a series of 15 photographs while the moon was entering and exiting Earth's umbra. Although it might seem that there should be no light on the moon when it is in Earth's shadow, sunlight is scattered into this region by Earth's atmosphere. This task was an attempt to measure by photographic photometry the amount of scattered light reaching the moon. The four views from upper left to lower right were selected to show the moon as it entered Earth's umbra. The first is a four-second exposure which was taken at the moment when the moon had just entered umbra; the second is a 15-second exposure taken two minutes after entry; the third, a 30-second exposure three minutes after entry; and the fourth is a 60-second exposure four minutes after entry. In all cases the light reaching the moon was so bright on the very high speed film (Eastman Kodak type 2485 emulsion) that the halation obscures the lunar image, which should be about one-third as big as the circle of light. The background star field is clearly evident, and this is very important for these studies. The spacecraft was in full sunlight when these photographs were taken, and it was pointed almost directly away from the sun so that the windows and a close-in portion of the camera's line-of-sight were in shadow. The environment around the vehicle at this time appears to be very "clean" with no light scattering particles noticeable.

S71-38189 (26 June 1971) --- An artist's concept showing the final steps of readying the Apollo 15 Lunar Roving Vehicle (LRV) or Rover 1 for mobility on the lunar surface.

This is a photo of the Apollo 15 Lunar Module, Falcon, on the lunar surface. Apollo 15 launched from Kennedy Space Center (KSC) on July 26, 1971 via a Saturn V launch vehicle. Aboard was a crew of three astronauts including David R. Scott, Mission Commander; James B. Irwin, Lunar Module Pilot; and Alfred M. Worden, Command Module Pilot. The first mission designed to explore the Moon over longer periods, greater ranges and with more instruments for the collection of scientific data than on previous missions, the mission included the introduction of a $40,000,000 lunar roving vehicle (LRV) that reached a top speed of 16 kph (10 mph) across the Moon's surface. The successful Apollo 15 lunar landing mission was the first in a series of three advanced missions planned for the Apollo program. The primary scientific objectives were to observe the lunar surface, survey and sample material and surface features in a preselected area of the Hadley-Apennine region, setup and activation of surface experiments and conduct in-flight experiments and photographic tasks from lunar orbit. Apollo 15 televised the first lunar liftoff and recorded a walk in deep space by Alfred Worden. Both the Saturn V rocket and the LRV were developed at the Marshall Space Flight Center.

jsc2011e118359 - Panorama view of Apollo 15 lunar surface photos south of Station 2 taken by lunar module pilot James B. Irwin. Astronaut David R. Scott, mission commander, performs a task at the Lunar Roving Vehicle parked on the edge of Hadley Rille (Rima Hadley) during the first moonwalk of the mission. The panoramas were built by combining Apollo 15 images starting with frame AS15-85-11448 thru end frame AS15-85-11453. The panoramic images received minimal retouching by NASA imagery specialists, including the removal of lens flares that were problematic in stitching together the individual frames and blacking out the sky to the lunar horizon. These adjustments were made based on observations of the Moon walkers who reported that there are no stars visible in the sky due to the bright lunar surface reflection of the Sun.

This montage depicts the flight crew patches for the manned Apollo 7 thru Apollo 17 missions. The Apollo 7 through 10 missions were basically manned test flights that paved the way for lunar landing missions. Primary objectives met included the demonstration of the Command Service Module (CSM) crew performance; crew/space vehicle/mission support facilities performance and testing during a manned CSM mission; CSM rendezvous capability; translunar injection demonstration; the first manned Apollo docking, the first Apollo Extra Vehicular Activity (EVA), performance of the first manned flight of the lunar module (LM); the CSM-LM docking in translunar trajectory, LM undocking in lunar orbit, LM staging in lunar orbit, and manned LM-CSM docking in lunar orbit. Apollo 11 through 17 were lunar landing missions with the exception of Apollo 13 which was forced to circle the moon without landing due to an onboard explosion. The craft was,however, able to return to Earth safely. Apollo 11 was the first manned lunar landing mission and performed the first lunar surface EVA. Landing site was the Sea of Tranquility. A message for mankind was delivered, the U.S. flag was planted, experiments were set up and 47 pounds of lunar surface material was collected for analysis back on Earth. Apollo 12, the 2nd manned lunar landing mission landed in the Ocean of Storms and retrieved parts of the unmanned Surveyor 3, which had landed on the Moon in April 1967. The Apollo Lunar Surface Experiments Package (ALSEP) was deployed, and 75 pounds of lunar material was gathered. Apollo 14, the 3rd lunar landing mission landed in Fra Mauro. ALSEP and other instruments were deployed, and 94 pounds of lunar materials were gathered, using a hand cart for first time to transport rocks. Apollo 15, the 4th lunar landing mission landed in the Hadley-Apennine region. With the first use of the Lunar Roving Vehicle (LRV), the crew was bale to gather 169 pounds of lunar material. Apollo 16, the 5th lunar landing mission, landed in the Descartes Highlands for the first study of highlands area. Selected surface experiments were deployed, the ultraviolet camera/spectrograph was used for first time on the Moon, and the LRV was used for second time for a collection of 213 pounds of lunar material. The Apollo program came to a close with Apollo 17, the 6th and final manned lunar landing mission that landed in the Taurus-Littrow highlands and valley area. This mission hosted the first scientist-astronaut, Schmitt, to land on the Moon. The 6th automated research station was set up, and 243 ponds of lunar material was gathered using the LRV.

S71-41511 (2 Aug. 1971) --- The Apollo 15 Lunar Module (LM) "Falcon" is seen only seconds before ascent stage liftoff in this color reproduction taken from a transmission made by the RCA color television camera mounted on the Lunar Roving Vehicle (LRV). The LRV was parked about 300 feet east of the LM. The LRV-mounted TV camera, remotely controlled from the Mission Control Center (MCC), made it possible for people on Earth to watch the LM's launch from the moon. The LM liftoff was at 171:37 ground elapsed time. The "Falcon" ascent stage, with astronauts David R. Scott, commander; and James B. Irwin, lunar module pilot, aboard, returned from the lunar surface to rejoin the Command and Service Modules (CSM) orbiting the moon. Astronaut Alfred M. Worden, command module pilot, remained with the CSM in lunar orbit while Scott and Irwin explored the moon. The LM descent stage is used as a launching platform and remains behind on the moon. This is part one of a four-part sequence.
