…
4/21/09
| Description |
Aracar volcano is one of many volcanoes in the Andes Range that is located just east of the Argentina-Chile border. Well-preserved lava flows are found at its base. Prior to a report of ash columns from the summit in 1993, the volcano was not known to be active and very little is known of the volcano's age and history. Salars, the large whitish features are very common in the arid Andes. The term salar is used exclusively of the saltwater wetlands of the Puna (high Andes) and can describe not only salt lakes but also temporary marshes, shallow lakes and lagoons, or simply salt crust. The nearby Salar del Hombre Muerto is being put into mineral production. The endeavor is expected to become one of Argentina's biggest mines, producing up to 20,000 tons of lithium carbonate and lithium chloride per year, to be extracted by pumping from the area's lithium-rich saltbeds. This image was taken from the space shuttle on Feb. 20, 2000. Image Credit: NASA/JPL/UCSD/JSC |

Patagonian Ice Fields

Patagonian Ice Fields |
| date |
04.14.1994 |
| description |
This pair of images illustrates the ability of multi-parameter radar imaging sensors such as the Spaceborne Imaging Radar-C/X-band Synthetic Aperture radar to detect climate- related changes on the Patagonian ice fields in the Andes Mountains of Chile and Argentina. The images show nearly the same area of the south Patagonian ice field as it was imaged during two space shuttle flights in 1994 that were conducted five-and-a-half months apart. The images, centered at 49.0 degrees south latitude and 73.5 degrees west longitude, include several large outlet glaciers. The images were acquired by SIR-C/X-SAR on board the space shuttle Endeavour during April and October 1994. The top image was acquired on April 14, 1994, at 10:46 p.m. local time, while the bottom image was acquired on October 5,1994, at 10:57 p.m. local time. Both were acquired during the 77th orbit of the space shuttle. The area shown is approximately 100 kilometers by 58 kilometers (62 miles by 36 miles) with north toward the upper right. The colors in the images were obtained using the following radar channels: red represents the C-band (horizontally transmitted and received), green represents the L-band (horizontally transmitted and received), blue represents the L-band (horizontally transmitted and vertically received). The overall dark tone of the colors in the central portion of the April image indicates that the interior of the ice field is covered with thick wet snow. The outlet glaciers, consisting of rough bare ice, are the brightly colored yellow and purple lobes which terminate at calving fronts into the dark waters of lakes and fiords. During the second mission the temperatures were colder and the corresponding change in snow and ice conditions is readily apparent by comparing the images. The interior of the ice field is brighter because of increased radar return from the dryer snow. The distinct green/orange boundary on the ice field indicates an abrupt change in the structure of the snowcap, a direct indication of the steep meteorological gradients known to exist in this region. The bluer color of the outlet glaciers is probably due to a thin snow cover. A portion of the terminus of the outlet glacier at the top left center of the images has advanced approximately 600 meters (1,970 feet) in the five-and-a-half months between the two missions. Because of the persistent cloud cover this observation was only possible by using the orbiting, remote imaging radar system. P-45740 |

Cold and Snow in South America |
| Description |
As winter settles over the Southern Hemisphere, South America has been lashed with snow, heavy rain and intense cold since the final week of June 2004. In southern Peru, heavy snow has collapsed hundreds of homes and buildings, and killed over 75,000 farm animals. The country is struggling to provide emergency provisions to people in the poverty-stricken region, many of whom are being treated for cold-related illnesses such as pneumonia. In many mountain regions, the temperature has plummeted to -20 Celsius (-4 Fahrenheit). The cold weather also caused deaths in Argentina and Chile. Unusually cold temperatures, down to -7 Celsius (19.4 Fahrenheit), chilled southern Brazil. This Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) image shows the snow in the mountains of southern Peru and northern Chile and Bolivia. Unlike the clouds that litter the scene, the snow clings to the contours of the mountain peaks. The image was acquired on July 13, 2004, by MODIS on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite.

Maipo Volcano, Chile
| Title |
Maipo Volcano, Chile |
| Description |
The high peaks of the Andes form the backbone of South America and the political border between Chile and Argentina. Formed from the subduction of the Nazca Plate under the South American Plate, the south-central Andes also includes several major volcanoes. One of the most active border volcanoes is Volcan Maipo, located just southeast of Santiago, Chile. The volcano's summit (5264m) rests in the large Diamante Caldera, and is defined by a radial drainage pattern highlighted by snow cover (center right of image). Lava flows from an 1826 eruption blocked drainage within the caldera, forming Lake Diamante. The lake is a popular tourist destination. Maipo's last significant eruption was in 1908. Imagery of the region from the International Space Station includes seasonal observations—this image shows the volcano near the southern hemisphere spring equinox. The lake, just east of Maipo's peak, is still ice covered. However, the increasing temperatures of spring are suggested by a muddy-looking streak near the lower left corner. The streak appears to be a landslide or avalanche that flowed westward down a rugged slope, possibly triggered by instability in the snowpack due to snow melt. Astronaut photograph ISS009-E-22625 [ http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS009&roll=E&frame=22625 ] was acquired September 14, 2004 with a Kodak 760C digital camera with a 180 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The International Space Station Program [ http://spaceflight.nasa.gov/ ] supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. [ http://eol.jsc.nasa.gov/ ] |

Fires in Argentina |
| Description |
Scattered fires were burning in western Argentina (center) on November 19, 2003. The dry, rugged Andes Mountains to the left of image center give way to a vast plain, which is extensively used for agriculture. This image and active fire detections (marked in red) were captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS' maximum spatial resolution of 250 meters.

Patagonian Glacier
| Title |
Patagonian Glacier |
| Description |
This image of a Patagonian glacier was aqcuired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on May 2, 2000. Patagonia is a mountainous region spanning the border between Chile and Argentina near the southern tip of South America. The image covers an area of 36 x 30 km?the full-size image has a resolution of 15 meters per pixel. Vegetation appears red in the image, which is a false-color composite of near-infrared, red, and green light displayed as red, green, and blue, respectively. This large glacier is riddled with crevasses?deep cracks in the ice. The semi-circular ridge at the far left of the image is composed of rock and soil carried there by the glacier which was even larger in the past. This type of feature is called a ?terminal moraine?. The pools of water at the foot of the glacier are light-colored due to the fine silt suspended in them. A braided stream winds through more silt deposited by the glacier and cuts through the terminal moraine about one third of the way down from its top. Along the right side of the image are a series of parallel valleys that were likely cut by arms of the glacier which have since receded.

Wildfires in Chile |
| Description |
About 400 miles south of Santiago, Chile, the dense smoke from numerous forest fires stretched out over the Pacific Ocean on February 5, 2002. This true-color MODIS image shows fires indicated with red dots (boxes in the high-resolution imagery) located near the city of Temuco. The fires were burning near several national parks and nature reserves in an area of the Chilean Andes where tourism is very popular. To the southeast of the fires, the vegetation along the banks of the R¡o Negro in Argentina stands out in dark green.

STS-55 Earth observation of Altiplano ash/dust plume in Argentina |
| Description |
STS-55 Earth observation taken from Columbia, Orbiter Vehicle (OV) 102, shows several plumes of blowing material over northern Argentina. All plumes originate downwind of the recent volcanic eruption of Lascar Volcano (just over the border in northern Chile). It seems most likely, therefore, that the blown material is dust-sized particles of ash that was deposited on the high Andean plateau by Lascar during the eruption of 04-20-93. The large, dense, V-shaped plume in this frame is about 40 kilometers long. It is blowing eastwards from a point about 100 km southeast of Lascar. On 05-10-93, images from the AVHRR sensor on the environmental satellite NOAA-11 showed the dust from these parts of Altiplano reaching the lowlands hundreds of kilometers to the east. This photo was recorded on 05-04-93 at 19 hours 10 minutes 38 seconds GMT. |

Perspective view of shaded relief, color as height, Patagonia, Argentina |
| Original Caption Released with Image |
This perspective view of Patagonia, Argentina shows a spectacular landscape formed by volcanoes, rivers, and wind. The area is located just east of the narrow range of the Andes Mountains, about 100 kilometers (62 miles) east of the border with Chile. Interesting features include basalt-capped mesas (top) and young volcanic cones (left foreground). Geologists will use SRTM topographic data to study the interaction of volcanic, climatic and erosional processes. This shaded relief perspective view was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains about 1100 meters (3600 feet) of total relief. To emphasize subtle differences in topography, the relief is exaggerated by a factor of 5. The Shuttle Radar Topography Mission (SRTM), launched on February 11,2000, uses 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. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) and the German (DLR) and Italian (ASI)space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC. Size: 70 km (43 miles) x 70 km (43 miles) Location: 41 deg. South lat., 69 deg.

Shaded relief, color as height Patagonia, Argentina |
| Original Caption Released with Image |
This topographic image of Patagonia, Argentina shows a spectacular landscape formed by volcanoes, rivers, and wind. The area is located just east of the narrow range of the Andes Mountains, about 100 kilometers (62 miles) east of the border with Chile. Interesting features include basalt-capped mesas with sinkholes (lower center), arcuate ridges of windblown beach sands downwind from a salty desert lake (upper center), young volcanic cones(right), and at least one case of what geologists call "inverted relief". This happens when lava flows down a valley in soft material and then the soft material is eroded away leaving the former valley as a ridge of lava. These ridges can be seen on the slopes of the volcano in the upper right. Geologists will use SRTM topographic data to study the interaction of volcanic, climatic and erosional processes. This shaded relief image was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains about 1100 meters(3600 feet) of total relief. White speckles on the face of some of the mountains are holes in the data caused by steep terrain. These will be filled using coverage from an intersecting pass. The Shuttle Radar Topography Mission (SRTM), launched on February 11,2000, uses 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. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) and the German (DLR) and Italian (ASI)space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC. Size: 225 km (140 miles) x 170 km (105 miles) Location: 41 deg. South lat., 69 deg. West lon. Orientation: North toward upper right Original Data Resolution: 30 meters (99 feet) Date Acquired: February 19, 2000 Image: NASA/JPL/NIMA |

South America as seen from the Apollo 7 spacecraft |
| Description |
This view of South America as seen from the Apollo 7 spacecraft during its 81st revolution of the earth from an altitude of 120 nautical miles. The port city of Antofagasta, Chile, is located in the half-moon shaped bay in the lower left portion of the picture. Beyond the coast is the Andean peak of Liullaillaco Volcano which rises 22,000 ft above sea level. At left center is the Chuquicamata copper mines located near Coloma. At the center of the photo, behind the large salt lake and atop a 19,000 ft high volcano, the countries of Bolivia, Argentina, and Chile meet at a common point. Below the clouds in the upper portion of the photo are the great plains known as the Gran Chaco. |

| Title |
Dust Storm, Andean Altiplano, South America |
| Description |
Most of the land surface and the clouds in the foreground of this westerly looking view are over the South American Andean Altiplano at the frontier between Chile and Argentina (26.5S, 66.5W). Chile is to the west near the top of the photo just beyond the dry salt lake (Salar de Arizaro) at the upper right. Very strong winds are picking up dust and blowing it to the SE across mountain mountain ranges into the Chaco Austral region of Argentina. |
