Name of Image Saturn V S-IVB Stages at the Sacramento Test Operations Facility
Date of Image 1967-01-01
Full Description This is a view of the Saturn V S-IVB (third) stage for the AS-209 (Apollo-Soyuz test project backup vehicle) on a transporter in the right foreground, and the S-IVB stage for AS-504 (Apollo 9 mission) being installed in the Beta Test Stand 1 at the SACTO facility in California. After the S-II (second) stage dropped away, the S-IVB (third) stage ignited and burned for about two minutes to place itself and the Apollo spacecraft into the desired Earth orbit. At the proper time during this Earth parking orbit, the S-IVB stage was re-ignited to speed the Apollo spacecraft to escape velocity and inject it and the astronauts into a moon trajectory. Developed and manufactured by the Douglas Aircraft Company in California, the S-IVB stage measures about 21.5 feet in diameter, about 58 feet in length, and is powered by a single 200,000-pound-thrust J-2 engine with a re-start capability. The S-IVB stage was also used on the second stage of the Saturn IB launch vehicle.

Space Laser Creates Artifici …
Title Space Laser Creates Artificial Star
Explanation Some astronomers don't like stars. Bright star fluctuations [ http://antwrp.gsfc.nasa.gov/apod/ap000725.html ] can indicate how the Earth's atmosphere [ http://csep10.phys.utk.edu/astr161/lect/earth/atmosphere.html ] is changing, but many times no bright star exists in the direction where atmospheric information is needed. So rather than try to eradicate existing stars with a laser, these astronomers create an artificial star [ http://www.llnl.gov/str/Guidestr.html ] of their own right where they need it -- with a laser [ http://www.howstuffworks.com/laser.htm ]. Subsequent observations of the artificial laser guide star [ http://op.ph.ic.ac.uk/laser.html ] can reveal information so detailed about the blurring effects of the Earth's atmosphere that much of this blurring can be removed [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2001PASP..113..366S ] by rapidly flexing the mirror. Such adaptive optic [ http://www.mtwilson.edu/Science/AdapOpt/Overview/ ] techniques allow high-resolution ground-based observations of real star [ http://antwrp.gsfc.nasa.gov/apod/ap000522.html ]s, planets [ http://antwrp.gsfc.nasa.gov/apod/ap000218.html ], and nebulae [ http://antwrp.gsfc.nasa.gov/apod/ap010220.html ]. Above [ http://www.noao.edu/image_gallery/html/im0216.html ], an artificial star was created with a four-watt laser at Richard B. Dunn Solar Telescope [ http://www.sunspot.noao.edu/DSTWWW/vtt-home.html ] on Sacramento Peak [ http://www.sunspot.noao.edu/index.html ] in New Mexico [ http://www.state.nm.us ].

Title ASTER Images San Francisco Bay Area
Original Caption Released with Image These images of the San Francisco Bay region were acquired on March 3, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. Each covers an area 60 kilometers (37 miles) wide and 75 kilometers (47 miles) long. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image the Earth for the next 6 years to map and monitor the changing surface of our planet. Upper Left: The color infrared composite uses bands in the visible and reflected infrared. Vegetation is red, urban areas are gray, sediment in the bays shows up as lighter shades of blue. Thanks to the 15 meter (50-foot) spatial resolution, shadows of the towers along the Bay Bridge can be seen. Upper right: A composite of bands in the short wave infrared displays differences in soils and rocks in the mountainous areas. Even though these regions appear entirely vegetated in the visible, enough surface shows through openings in the vegetation to allow the ground to be imaged. Lower left: This composite of multispectral thermal bands shows differences in urban materials in varying colors. Separation of materials is due to differences in thermal emission properties, analogous to colors in the visible. Lower right: This is a color coded temperature image of water temperature, derived from the thermal bands. Warm waters are in white and yellow, colder waters are blue. Suisun Bay in the upper right is fed directly from the cold Sacramento River. As the water flows through San Pablo and San Francisco Bays on the way to the Pacific, the waters warm up. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader, Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface. The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands, evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface heat balance.

Title Northern California and San Francisco Bay
Original Caption Released with Image The left image of this pair was acquired by MISR's nadir camera on August 17, 2000 during Terra orbit 3545. Toward the top, and nestled between the Coast Range and the Sierra Nevadas, are the green fields of the Sacramento Valley. The city of Sacramento is the grayish area near the right-hand side of the image. Further south, San Francisco and other cities of the Bay Area are visible. On the right is a zoomed-in view of the area outlined by the yellow polygon. It highlights the southern end of San Francisco Bay, and was acquired by MISR's airborne counterpart, AirMISR, during an engineering check-out flight on August 25, 1997. AirMISR flies aboard a NASA ER-2 high-altitude aircraft and contains a single camera that rotates to different view angles. When this image was acquired, the AirMISR camera was pointed 70 degrees forward of the vertical. Colorful tidal flats are visible in both the AirMISR and MISR imagery. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. For more information: http://www-misr.jpl.nasa.gov

Title SRTM Perspective View with Landsat Overlay: San Joaquin Valley, California
Original Caption Released with Image San Joaquin, the name given to the southern portion of California's vast Central Valley, has been called the world's richest agricultural valley. In this perspective view generated using data from the Shuttle Radar Topography Mission and an enhanced Landsat image, we are looking toward the southwest over a checkerboard pattern of agricultural fields. Mt. Pinos, a popular location for stargazing at 2,692 meters (8,831 feet) looms above the valley floor and is visible on the left side of the image. The productive southern San Joaquin is in reality a desert, averaging less than 12.7 cm (5 inches) of rain per year. Through canals and irrigation, the region nurtures some two hundred crops including grapes, figs, apricots, oranges, and more than 4,047 square-km (1,000,000 acres) of cotton. The California Aqueduct, transporting water from the Sacramento River Delta through the San Joaquin, runs along the base of the low-lying Wheeler Ridge on the left side of the image. The valley is not all agriculture though. Kern County, near the valley's southern end, is the United States' number one oil producing county, and actually produces more crude oil than Oklahoma. For visualization purposes, topographic heights displayed in this image are exaggerated two times. Colors, from Landsat data, approximate natural color. The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface. To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200 feet)long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif, for NASA's Earth Science Enterprise,Washington, D.C. JPL is a division of the California Institute of Technology in Pasadena.

Title Perspective View with Landsat Overlay, Sacramento, Calif.
Original Caption Released with Image California's state capitol, Sacramento, can be seen clustered along the American and Sacramento Rivers in this computer-generated perspective viewed from the west. Folsom Lake is in the center and the Sierra Nevada is above, with the edge of Lake Tahoe just visible at top center. This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced color Landsat 5satellite image. Topographic expression is exaggerated two times. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR)that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies.

Title Northern California near San Francisco
Description A part of northern California centered near San Francisco Bay (38.0N, 122.0W) photographed at 3 p.m. January 1, 1974, from the Skylab space station in Earth orbit. This near vertical view encompasses the coastline from Monteray Bay (right) to about 50 miles north of Point Reyes (left) and includes, from bottom to top, San Francisco Bay (center), Sacramento Valley (left center), San Joaquin Valley (right center), and the snow-covered Sierra Nevada. Afternoon shadows sharply delineate a valley which parallels San Francisco Bay, crosses Point Reyes, and lies between the Bay and the Pacific coastline. This valley marks the location of the San Andreas Fault. Forces acting on the crust are causing the land west (bottom) of the fault line to move north relative to land on the east side. Agricultural areas in the Sacramento and San Joaquin Valleys are indicated by the tan areas which are easily discerned in contrast to the green-gray background.

Title San Francisco Bay, California as seen from STS-59
Description San Francisco Bay as seen from STS-59. View is oriented with the sea up. The delta of the combined Sacramento and San Joaquin Rivers occupies the foreground with San Francisco Bay in the middle distance, then the Pacific Ocean. Variations in water color caused both by sediment load and by wind streaking strike the eye. Man-made features dominate this scene. The Lafayette/Concord complex is left of the bay head, Vallejo is to the right, the Berkeley/Oakland complex rims the shoreline of the main bay, and San Francisco fills the peninsula beyond. Salt-evaporation ponds contain differently-colored algae depending on salinity. The low altitude (less than 120 nautical miles) and unusually-clear air combine to provide unusually-strong green colors in this Spring scene.
