Mount Saint Helens |
| description |
Mount Saint Helens exemplifies how Earth's topographic form can change greatly even within our lifetimes. The mountain is one of several prominent volcanoes of the Cascade Range that stretches from British Columbia, Canada, southward through Washington, Oregon and into northern California. Mount Adams (left background) and Mount Hood (right background) are also seen in this view, which was created entirely from elevation data produced by the Shuttle Radar Topography Mission. Prior to 1980, Mount Saint Helens had a shape roughly similar to other Cascade peaks, a tall, bold, irregular conic form that rose to 9,677 feet (2,950 meters). However, the explosive eruption of May 18, 1980, caused the upper 1,300 feet (400 meters) of the mountain to collapse, slide and spread northward, covering much of the adjacent terrain (lower left), leaving a crater atop the greatly shortened mountain. Subsequent eruptions built a volcanic dome within the crater, and the high rainfall of this area lead to substantial erosion of the poorly consolidated landslide material. Eruptions at Mount Saint Helens subsided in 1986, but renewed volcanic activity here and at other Cascade volcanoes is inevitable. Predicting such eruptions still presents challenges, but migration of magma within these volcanoes often produces distinctive seismic activity and minor but measurable topographic changes that can give warning of a potential eruption.

| Title |
Fires in Central Canada |
| Description |
A blanket of smoke from scores of wildfires hung over central Canada on July 4, 2006. This image of the area was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite that afternoon at 2:40 p.m. Central Standard Time. Places where MODIS detected active fires are marked in red. In this image, fires are burning in British Columbia, Alberta, and Saskatchewan. Smoke appears light gray or yellow-gray, where it is very thick. The smoke spreads over a wide area, reaching northward into Northwest Territories and eastward into Manitoba. Several thousand people have been forced to evacuate their homes because of various wildfires throughout western and central Canada off and on since late June. NASA image created by Jesse Allen, Earth Observatory, using data provided by the MODIS Rapid Response [ http://rapidfire.sci.gsfc.nasa.gov/ ] team. |

Manicouagan Impact Crater on Earth |
| Explanation |
The Manicouagan Crater [ http://www.linkdirectory.com/airphoto/1030.html ] in northern Canada [ http://www.odci.gov/cia/publications/factbook/geos/ca.html ] is one of the oldest impact craters [ http://observe.ivv.nasa.gov/nasa/exhibits/craters/impact_home.html ] known. Formed during a surely tremendous impact [ http://antwrp.gsfc.nasa.gov/apod/ap990711.html ] about 200 million years ago, the present day terrain supports a 70-kilometer diameter hydroelectric reservoir [ http://www.ilec.or.jp/database/nam/nam-26.html ] in the telltale form of an annular lake [ http://epod.usra.edu/archive/epodviewer.php3?oid=40640 ]. The crater itself has been worn away by the passing of glaciers [ http://www.glacier.rice.edu/land/5_whatisaglacier.html ] and other erosional processes. Still, the hard rock [ http://duke.usask.ca/~reeves/prog/geoe118/geoe118.011.html ] at the impact site has preserved much of the complex impact structure [ http://antwrp.gsfc.nasa.gov/apod/ap960120.html ] and so allows scientists a leading case to help understand large impact features on Earth [ http://www.lpi.usra.edu/publications/slidesets/impacts.html ] and other [ http://antwrp.gsfc.nasa.gov/apod/ap001213.html ap960906.html ] Solar System bodies. Also visible above [ http://earth.jsc.nasa.gov/lores.cgi?PHOTO=STS009-48-3139 ] is the vertical fin of the Space Shuttle [ http://antwrp.gsfc.nasa.gov/apod/ap990411.html ] Columbia from which the picture was taken in 1983. |

Kalamalka Lake Eclipse
| Title |
Kalamalka Lake Eclipse |
| Explanation |
Recorded on August 28th [ http://www.spaceweather.com/eclipses/ gallery_28aug07_page2.htm ], this serene total lunar eclipse sequence looks southwest down Kalamalka Lake toward the lights of Coldstream [ http://maps.google.com/maps?q=Coldstream,+BC,+Canada&ie=UTF8 &ll=50.225355,-119.268951&spn=0.240294,0.320663&t=h&z=11&om=1 ], British Columbia. An exposure every 4 minutes captured the Moon's position and eclipse phase, until the Moon set behind the town lights and a hill on the horizon. In fact, the sequence effectively measures the duration of the total phase of the eclipse [ http://www.mreclipse.com/Special/LEprimer.html ]. Around 270 BC, the Greek astronomer Aristarchus [ http://www-groups.dcs.st-and.ac.uk/~history/ Mathematicians/Aristarchus.html ] also measured the duration of lunar eclipses - though probably without the benefit of digital clocks [ http://itotd.com/articles/297/ revenge-of-the-analog-clock/ ] and cameras. Still, using geometry, he devised [ http://www.phy6.org/stargaze/Shipprc2.htm ] a simple and impressively accurate way to calculate the Moon's distance, in terms of the radius of planet Earth, from the eclipse duration. |

Manicouagan Crater in northern Canada is one of the oldest impact craters known [ http://antwrp.gsfc.nasa.gov/apod/ap000226.html ]. Formed about 200 million years ago, the present day terrain supports a 70-kilometer diameter hydroelectric reservoir [ http://www.ilec.or.jp/database/nam/nam-26.html ] in the telltale form of an annular lake [ http://epod.usra.edu/archive/epodviewer.php3?oid=40640 ]. The crater itself has been worn away by the passing of glaciers [ http://www.glacier.rice.edu/land/5_whatisaglacier.html ] and other erosional processes. Still, the hard rock at the impact site has preserved much of the complex impact structure [ http://antwrp.gsfc.nasa.gov/apod/ap960120.html ] and so allows scientists a leading case to help understand large impact features [ http://www.lpi.usra.edu/publications/slidesets/ impacts.html ] on Earth [ http://antwrp.gsfc.nasa.gov/apod/ap990610.html ] and other [ http://antwrp.gsfc.nasa.gov/apod/ap010513.html ] Solar System bodies.

| Title |
Anaglyph, North America |
| Original Caption Released with Image |
This anaglyph (stereoscopic view) of North America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south and 736 meters east-west in central North America), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the North American continent is readily apparent. Active tectonics (structural deformation of the Earth's crust) along and near the Pacific North American plate boundary creates the great topographic relief seen along the Pacific coast. Earth's crustal plates converge in southern Mexico and in the northwest United States, melting the crust and producing volcanic cones. Along the California coast, the plates are sliding laterally past each other, producing a pattern of slices within the San Andreas fault system. And, where the plates are diverging, the crust appears torn apart as one huge tear along the Gulf of California (northwest Mexico), and as the several fractures comprising the Basin and Range province (in and around Nevada). Across the Great Plains, erosional patterns dominate, with stream channels surrounding and penetrating the remnants of older smooth slopes east of the Rocky Mountains. This same erosion process is exposing the bedrock structural patterns of the Black Hills in South Dakota and the Ozark Mountains in Arkansas. Lateral erosion and sediment deposition by the Mississippi River has produced the flatlands of the lower Mississippi Valley and the Mississippi Delta. To the north, evidence of the glaciers of the last ice age is widely found, particularly east of the Canadian Rocky Mountains and around the Great Lakes. From northeastern British Columbia, across Alberta, Saskatchewan, and Manitoba to North Dakota and Minnesota, huge striations clearly show the flow pattern of the glaciers. And southwest of Lakes Michigan, Huron, and Erie, arcing ridges of sediment, called terminal moraines, show where glaciers dumped sediment at their melting ends. In eastern Canada, New York, and New England, the terrain has been scoured by glaciers, and eroded by streams, particularly along fractures in the bedrock. In Labrador and Quebec, the Mistastin, Manicougan, and Clearwater Lakes meteor impact craters can also be seen. Further south, narrow curving ridges of upturned and eroded layered rocks form most of the Appalachian Mountains. In contrast, around the Caribbean Sea region (Yucatan, Florida, and the Bahamas), flat-lying, stable limestone platforms are common, while the most eastern islands of the Caribbean include active volcanoes along another convergence zone of tectonic plates. This, anaglyph was created by deriving a shaded relief image from the SRTM data, draping it back over the SRTM elevation model, and then generating two differing perspectives, one for each eye. Illumination is from the north (top). When viewed through special glasses, the anaglyph is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter. Elevation data used in this image were acquired by the 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. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C.

Two visualization methods were combined to produce the image: shading and color coding of, topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark.

This natural-color image combines cloud-free data from over 500 Multi-angle Imaging SpectroRadiometer (MISR) orbits with shaded relief Digital Terrain Elevation models from the Shuttle Radar Topography Mission (SRTM) and other sources. An astonishing diversity of geological features, ecological systems and human landscapes across North America is indicated within the image, which spans from 56N, 136W at the upper left to 16N 48W at lower right. In addition to the contiguous United States, the scene spans from British Columbia in the northwest to Newfoundland in the northeast, and extends eastward to the lonely Bermuda Islands and southward to the Bahamas, Cuba and Mexico. Draped in green, the eastern and central United States and Canada contrast with the vibrant geology that is laid bare across the arid portions of the southwestern United States and central Mexico. Along Mexico's east coast, the lush vegetation to the east of the Sierra Madre mountain range indicates the orographic rainfall gradient along this subtropical-tropical coast. In the high Rocky Mountains and in British Columbia's Coast Range, many peaks remain snow-covered year-round. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82 north and 82 south latitude. This data product was generated from a portion of the imagery acquired during years 2000 - 2004. The image is displayed in an Albers Conic Equal Area projection with the projection center at 36 North, 92 West. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

(about 100 miles) Location: 46.2 degrees North latitude, 122.2 degrees West longitude Orientation: View Southeast Image Data: Shaded and colored SRTM elevation model Date Acquired: February 2000, Mount Saint Helens is a prime example of how Earth's topographic form can greatly change even within our lifetimes. The mountain is one of several prominent volcanoes of the Cascade Range that stretches from British Columbia, Canada, southward through Washington, Oregon, and into northern California. Mount Adams (left background) and Mount Hood (right background) are also seen in this view, which was created entirely from elevation data produced by the Shuttle Radar Topography Mission. Prior to 1980, Mount Saint Helens had a shape roughly similar to other Cascade peaks, a tall, bold, irregular conic form that rose to 2950 meters (9677 feet). However, the explosive eruption of May 18, 1980, caused the upper 400 meters (1300 feet) of the mountain to collapse, slide, and spread northward, covering much of the adjacent terrain (lower left), leaving a crater atop the greatly shortened mountain. Subsequent eruptions built a volcanic dome within the crater, and the high rainfall of this area lead to substantial erosion of the poorly consolidated landslide material. Eruptions at Mount Saint Helens subsided in 1986, but renewed volcanic activity here and at other Cascade volcanoes is inevitable. Predicting such eruptions still presents challenges, but migration of magma within these volcanoes often produces distinctive seismic activity and minor but measurable topographic changes that can give warning of a potential eruption. Three visualization methods were combined to produce this image: shading of topographic slopes, color coding of topographic height, and then projection into a perspective view. The shade image was derived by computing topographic slope in the northeast-southwest (left to right) direction, so that northeast slopes appear bright and southwest slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. The perspective view simulates the geometry of the surface as it would be viewed on a clear day. Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000.

This natural-color image from the Multi-angle Imaging SpectroRadiometer (MISR) captures the beauty of the western United States and Canada. Data from 45 swaths from MISR's vertical-viewing (nadir) camera were combined to create this cloud-free mosaic. The image extends from 48° N 128° W in the northwest, to 32°N, 104° W in the southeast, and has been draped over a shaded relief Digital Terrain Elevation Model from the United States Geological Survey. The image area includes much of British Columbia, Alberta and Saskatchewan in the north, and extends southward to California, Arizona and New Mexico. The snow-capped Rocky Mountains are a prominent feature extending through British Columbia, Montana, Wyoming, Colorado and New Mexico. Many major rivers originate in the Columbia Plateau region of Washington, Oregon and Idaho. The Colorado Plateau region is characterized by the vibrant red-colored rocks of the Painted Desert in Utah and Arizona, and in New Mexico, White Sands National Park is the large white feature in the Southeast corner of the image with the Malpais lava flow just to its North. The southwest is dominated by the Mojave Desert of California and Nevada, California's San Joaquin Valley, the Los Angeles basin and the Pacific Ocean. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously from pole to pole, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during 2000-2002. The panels utilize data from blocks 45 to 65 within World Reference System-2 paths 31 to 53.

Cascade Mtns. Oregon |
| Original Caption Released with Image |
The ground near one of the long-dormant Three Sisters volcanoes in the Cascade Mountains of west-central Oregon has risen approximately 10centimeters in a 10-by-20-km parcel since 1996, meaning that magma or underground lava is slowly flowing into the area, according to a research team from the U.S. Geological Survey. The Three Sisters area -- which contains five volcanoes -- is only about 170 miles from Mount St. Helens, which erupted in 1980. Both are part of the Cascades Range, a line of 27volcanoes stretching from British Columbia in Canada to northern California. This perspective view was created by draping a simulated natural color ASTER image over digital topography from the U.S. Geological Survey National Elevation Dataset. This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. 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 Earth for the next 6 years to map and monitor the changing surface of our planet. 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 Economy, 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, Bjorn Eng of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The Terra mission is part of NASA's Earth Science Enterprise, along-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system. 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.
