AS16-114-18439 (22 April 1972) --- Astronaut Charles M. Duke Jr., lunar module pilot, stands in the shadow of the Lunar Module (LM) behind the ultraviolet (UV) camera which is in operation. This photograph was taken by astronaut John W. Young, commander, during the mission's second extravehicular activity (EVA). The UV camera's gold surface is designed to maintain the correct temperature. The astronauts set the prescribed angles of azimuth and elevation (here 14 degrees for photography of the large Magellanic Cloud) and pointed the camera. Over 180 photographs and spectra in far-ultraviolet light were obtained showing clouds of hydrogen and other gases and several thousand stars. The United States flag and Lunar Roving Vehicle (LRV) are in the left background. While astronauts Young and Duke 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.

AS15-82-11057 (2 Aug. 1971) --- The Lunar Module (LM) "Falcon" is photographed against the barren lunarscape during the third Apollo 15 lunar surface extravehicular activity (EVA) at the Hadley-Apennine landing site on the lunar nearside. This view is looking southeast. The Apennine Front is in the left background; and Hadley Delta Mountain is in the right background. The object next to the United States flag is the Solar Wind Composition (SWC) experiment. Last Crater is to the right of the LM. Note bootprints and tracks of the Lunar Roving Vehicle (LRV). The light spherical object at the top is a reflection in the lens of the camera. While astronauts David R. Scott and James B. Irwin descended in the LM to explore the moon, astronaut Alfred M. Worden remained with the Command and Service Modules (CSM) in lunar orbit.

SL4-93-153 (February 1974) --- A vertical view of the Birmingham and central Alabama area is seen in this Skylab 4 Earth Resources Experiments Package S190-B (five-inch earth terrain camera) infrared photographed taken from the Skylab space station in Earth orbit. Illustrated here is the utility of color infrared film in depicting distribution of living vegetation in the 3,600 square mile Birmingham region. The Birmingham industrial complex, with a population of nearly 850,000, is the light gray area nestled in the valley between the northeast-trending ridges that are prominent topographic features in the southern Appalachian Mountains. The narrow ridges and adjacent valleys reflect folded and faulted sedimentary rocks, indicating the complex geological history of the region. Two major rivers and several reservoirs are easily distinguished in this photograph. Bankhand Lake, formed by a dam on the Black Warrior River, appears as bright blue west of Birmingham. Two lakes are formed by dams on the Goosa River east of Birmingham. Federal and state highways appear as thin white lines and are easily identified. Interstate 65 to Montgomery is the prominent white line extending southward from Birmingham. Power line clearings are visible in the center of the picture along the Goosa River, and can be traced northwestward to northern parts of Birmingham. The predominant deep red color of the picture is due to the reflections from living vegetation. In contrast are the light tan areas that commonly occur as rectangular patterns in the east part of the photograph and represent mature agricultural crops or grazing lands. Analysis of the photographic data from the earth terrain camera will be conducted by Dr. H. Jayroe of the Marshall Space Flight Center in developing analytical techniques.

SL4-93-167 (February 1974) --- A vertical view of the Kennedy Space Center and the Florida Atlantic coast area is seen in this Skylab 4 Earth Resources Experiments Package S190-B (five-inch earth terrain camera) infrared photography taken from the Skylab space station in Earth orbit. This photograph shows the major land-ocean features of the Florida coast near Vero Beach northward to Cape Canaveral and the KSC complex. The launch pads for the Skylab missions are clearly visible. Identification of living vegetation is possible through the use of the color infrared film. Various shades of red portray differences in the vegetation such as shown in the patterns in the agricultural area near Vero Beach. In the Kennedy Space Center, the nearly continuous and uniform red color shows that most of the land areas are heavily vegetated. The white coastal beach areas are strongly contrasted to the red land and the blue Atlantic Ocean. Old dunal areas in KSC are visible on Merritt Island which is separated from the Launch areas by the Banana River and the mainland by the Indian River. Federal and state highways and numerous causeways over the rivers are easily identified. The Florida mainland is partly shadowed by small white clouds which cast a pronounced shadow to the east of each cloud indicated the Sun is west of solar noon.

SL4-92-300 (February 1974) --- A near vertical view of the Mobile Bay, Alabama area is seen in this Skylab 4 Earth Resources Experiments Package S190-B (five-inch earth terrain camera) photograph taken from the Skylab space station in Earth orbit. North of Mobile the Tombigbee and Alabama Rivers join to form the Mobile River. Detailed configuration of the individual stream channels and boundaries can be defined as the Mobile River flows into Mobile Bay, and thence into the Gulf of Mexico. The Mobile River Valley with its numerous stream channels is a distinct light shade in contrast to the dark green shade of the adjacent areas. The red coloration of Mobile Bay reflects the sediment load carried into the Bay by the rivers. Variations in red color indicate sediment load and the current paths within Mobile Bay. The waterly movement of the along shore currents at the mouth of Mobile Bay is shown by the contrasting light blue of the sediment-laden current and the blue of the Gulf predominately. Agricultural areas east and west of Mobile Bay are characterized by a rectangular pattern in green to white shades. Color variations may reflect the type and growth cycle of crops. Agricultural areas (light gray-greens) are also clearly visible in other parts of the photograph. Interstate 10 extends from near Pascagoula, Mississippi eastward through Mobile to the outskirts of Pensacola, Florida. Analysis of the EREP photographic data will be undertaken by the U.S. Corps of Engineers to determine bay dynamic processes. Federal agencies participating with NASA on the EREP project are the Departments of Agriculture, Commerce, Interior, the Environmental Protection Agency and the Corps of Engineers.
