Description In this 1960 photograph, the seven original Mercury astronauts participate in U.S. Air Force survival training exercises at Stead Air Force Base in Nevada. Pictured from left to right are: L. Gordon Cooper, M. Scott Carpenter, John Glenn, Alan Shepard, Virgil I. Grissom, Walter Schirra and Donald K. Slayton. Portions of their clothing have been fashioned from parachute material, and all have grown beards from their time in the wilderness. The purpose of this training was to prepare astronauts in the event of an emergency or faulty landing in a remote area. Forty-five years ago today on May 24, 1962, Scott Carpenter went on to fly the second American manned orbital flight. He piloted his Aurora 7 spacecraft through three revolutions of the Earth, reaching a maximum altitude of 164 miles. The spacecraft landed in the Atlantic Ocean about 1,000 miles, about 1,609 kilometers, southeast of Cape Canaveral after the 4 hour, 54 minute flight. Image credit: NASA

Angora Fire
Title Angora Fire
Description South of Lake Tahoe, which straddles the Nevada-California state line, a large fire destroyed at least 165 homes over the weekend of June 23, 2007. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite shows the Angora Fire on June 24. The area in which MODIS detected actively burning fire is outlined in red. A plume of brownish-gray smoke spreads northeast. According to the June 25 report from the National Interagency Fire Center, the Angora Fire was burning in timber and grass, was about 1,800 acres, and was zero percent contained. The large image provided above has a spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response Team provides twice-daily [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA1 ] images of the region in additional resolutions and formats, including an infrared-enhanced version that makes the burned area stand out from the surrounding, unburned vegetation.

Angora Fire
Title Angora Fire
Description On the weekend of June 23, 2007, a wildfire broke out south of Lake Tahoe, which stretches across the California-Nevada border. By June 28, the Angora Fire [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14323 ] had burned more than 200 homes and forced some 2,000 residents to evacuate, according to The Seattle Times and the Central Valley Business Times. On June 27, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite captured this image of the burn scar left by the Angora fire. The burn scar is dark gray, or charcoal. Water bodies, including the southern tip of Lake Tahoe and Fallen Leaf Lake, are pale silvery blue, the silver color a result of sunlight reflecting off the surface of the water. Vegetation ranges in color from dark to bright green. Streets are light gray, and the customary pattern of meandering residential streets and cul-de-sacs appears throughout the image, including the area that burned. The burn scar shows where the fire obliterated some of the residential areas just east of Fallen Leaf Lake. According to news reports, the U.S. Forest Service had expressed optimism about containing the fire within a week of the outbreak, but a few days after the fire started, it jumped a defense, forcing the evacuation of hundreds more residents. Strong winds that had been forecast for June 27, however, did not materialize, allowing firefighters to regain ground in controlling the blaze. On June 27, authorities hoped that the fire would be completely contained by July 3. According to estimates provided in the daily report from the National Interagency Fire Center, [ http://www.nifc.gov/information.html ] the fire had burned 3,100 acres (about 12.5 square kilometers) and was about 55 percent contained as of June 28. Some mandatory evacuations remained in effect.

Heatwave in Southern Califor …
Title Heatwave in Southern California
Description September 5, 2007, marked the end of a week-long heat wave that led to 31 deaths and triggered power outages across southern California, reported the L.A. Times. Temperatures climbed above 38 degrees Celsius (100 Fahrenheit) when a high-pressure system blocked cool air from the Pacific. The effect of the heat wave on different locations in the Southwest is shown in this pair of images, taken on September 5, at 11:25 a.m. local time (18:25 UTC) by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Terra [ http://terra.nasa.gov/ ], in Northern California filters down from the top edge of the scene. NASA image created by Jesse Allen, using data obtained from the Goddard Land Processes data archives (LAADS). [ http://laads.gsfc.nasa.gov/ ], satellite. The photo-like, natural-color image (top) and corresponding land surface temperature image (bottom) illustrate the relationship between land cover, elevation, and temperature. The images show much of California and Nevada, and a smaller portion of Arizona and Utah. Not surprisingly, the hottest areas, shown in yellow, correspond with sparsely vegetated desert regions. In the natural-color image, the brush-covered Mojave Desert on the California-Nevada border is tan with splashes of pink where iron-rich sandstone is exposed. The small-leafed, woody vegetation provides little shade, allowing the Earth's surface to be exposed to the Sun. The rock-and-dirt desert absorbs sunlight, and temperatures climb (yellow areas of bottom image). The other hot spots in the image occur in the cactus-dotted Sonoran Desert, which encompasses the southernmost portions of inland California and southwestern Arizona, and the much smaller Colorado Desert west of the Salton Sea. Irrigated land south of the Salton Sea and along the Colorado River is a web of brown-green. The presence of water and vegetation in these irrigated areas makes the land cooler. Elevation also plays a role in the surface temperatures of the Sonoran Desert. Pockets of low-elevation land are much warmer than the lines of mountains that separate them, particularly in southwestern Arizona. The coolest parts of California, shown in purple and blue, are in the mountains, most prominently the Sierra Nevada, but also the San Bernardino Mountains east of Los Angeles. In the photo-like images, the mountain ranges are dark green, colored by trees. The vegetation cover and the high elevation keep the land cooler than surrounding low-elevation sites. The other significant cool spot in the image is the San Joaquin Valley. Like the irrigated farm land bordering the Salton Sea and the Colorado River, this area is kept cool by the presence of water and plants. The coldest areas in the image appear to be in Arizona, Utah, and Nevada, which are marked by streaks of dark purple. These cold signatures are from clouds.The final correlation between land cover and temperature can be seen in urban areas along the coast. In the photo-like image, Los Angles sprawls as a silver-gray patch from the coast to the San Bernardino Mountains. Since urban surfaces absorb heat, Los Angles is slightly warmer in the surface temperature image than the surrounding landscape. In the north, the San Francisco urban area is similarly warmer than its surroundings. Though the extreme temperatures raised the fire danger in Southern California, MODIS did not detect any fires in the region. Fires, marked with red dots, were burning in Central California south and east of San Francisco.

Title Heatwave in the Western United States
Description The oppressive heat that crept over parts of the western United States during the first few days of July 2007 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14380 ] took hold of the entire West during the week of July 4 through July 11. Deep red tones blanket every western state in this land surface temperature image, an indication that temperatures were warmer than in previous years. The image was made with data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite and shows temperatures recorded between July 4 and July 11, 2007, compared to the average of temperatures observed during the same period in 2000, 2001, and 2002. Areas that are warmer than during that three-year period are red, while cooler areas are blue. Triple-digit temperatures broke or matched records from Las Vegas, Nevada, to Great Falls, Montana, during this period. In this image, a cluster of red-black over eastern Washington, northern Idaho, and eastern Montana indicates that these regions experienced much warmer temperatures than in previous years. Western South Dakota (the Black Hills region) was also exceptionally warm. On the other end of the scale, Texas was much cooler than it had been in 2000, 2001, and 2002. Heavy rains pounded Texas on and off throughout this period, contributing to wide-spread flooding.

Title Heatwave in the Western United States
Description Extreme heat lingered over much of the western United States in early July 2007. Temperatures soared to triple digits, meeting or breaking records from Las Vegas, Nevada, to Great Falls, Montana, said news reports. The oppressive heat contributed to creating prime fire conditions, so that, when dry thunderstorms (lightning storms accompanied by little or no rain) rolled through on July 7, lightning sparked dozens of fast-moving wildfires. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14358 ] This image, created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite from June 26 though July 3, 2007, shows land surface temperatures compared to average temperatures observed during the same period in 2000, 2001, and 2002. Deep red across the Southwest and the Intermountain West indicate that temperatures were much higher than they were in 2000-2002. The Southeast also experienced warmer temperatures. Northern California, Oregon, and Washington appear to be cooler than in previous years, as indicated by the blue tones. The heat wave started mid-way through the week-long period shown in this image. While temperatures may have soared at the end of the period, cooler temperatures earlier in the week dominate the signal. Land surface temperatures from July 4-11 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14393 ] show that these areas warmed significantly the following week. The Southern Plains are dark blue where temperatures were much cooler than they had been in previous years. During this period, torrential rains drenched the region, causing wide-spread flooding in Texas and Oklahoma [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14363 ] and in Kansas and Missouri. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14383 ] The gray region over Kansas and Oklahoma is an area in which MODIS could not record the land's temperature because of perpetual cloud cover during the week-long period.

Drought in Southwestern Unit …
Title Drought in Southwestern United States
Description The southwestern United States pined for water in late March and early April 2007. This image is based on data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite from March 22 through April 6, 2007, and it shows the Normalized Difference Vegetation Index, or NDVI, for the period. In this NDVI color scale, green indicates areas of healthier-than-usual vegetation, and only small patches of green appear in this image, near the California-Nevada border and in Utah. Larger areas of below-normal vegetation are more common, especially throughout California. Pale yellow indicates areas with generally average vegetation. Gray areas appear where no data were available, likely due to persistent clouds or snow cover. According to the April 10, 2007, update from the U.S. Drought Monitor, [ http://www.drought.unl.edu/dm/monitor.html ] most of the southwestern United Sates, including Utah, Nevada, California, and Arizona, experienced moderate to extreme drought. The hardest hit areas were southeastern California and southwestern Arizona. Writing for the Drought Monitor, David Miskus of the Joint Agricultural Weather Facility reported that March 2007 had been unusually dry for the southwestern United States. While California's and Utah's reservoir storage was only slightly below normal, reservoir storage was well below normal for New Mexico and Arizona. In early April, an international research team published an online paper in Science noting that droughts could become more common for the southwestern United States and northern Mexico, as these areas were already showing signs of drying. Relying on the same computer models used in the Intergovernmental Panel on Climate Change (IPCC) report released in early 2007, the researchers who published in Science concluded that global warming could make droughts more common, not just in the American Southwest, but also in semiarid regions of southern Europe, Mediterranean northern Africa, and the Middle East.

Murphy Complex Fire
Title Murphy Complex Fire
Description When two large, previously separate wildfires (Rowland and Elk Mountain) near the Idaho-Nevada state line merged over the July 21 weekend, fire management officials renamed the incident as the Murphy Complex Fire. According to the morning report from the National Interagency Fire Center on July 23, 2007, the blaze had consumed more than 560,000 acres and was 15 percent contained. This image of the Murphy Complex Fire was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on July 22. Places where the sensor detected actively burning fire are outlined in red. The dry grassland and sagebrush terrain appears olive-tan, while the sprawling burned area appears deep brown. The large image provided above has a spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response Team provides twice-daily [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA1 ] images of the western United States in additional resolutions. Images of the separate fires were previously published in the Fires in Idaho and Eastern Oregon [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14398 ] event.

Title Fires in Idaho and Eastern Oregon
Description MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC, Strong winds fanned wildfires across the western United States on July 19, 2007. The hot, dry, windy conditions led the National Interagency Fire Center to move to a National Preparedness Level [ http://www.nifc.gov/fireinfo/pl_desc.html ] of 5 on a five-point scale, indicating that the fires were numerous, large, and widespread enough to potentially exhaust fire-fighting resources. More than a million acres were burning across the United States in 72 large wildfires on July 19, 2007, said the National Interagency Fire Center. [ http://www.nifc.gov/fire_info/nfn.htm ] Among the largest fires were the Rowland and Elk Mountain fires burning in southwestern Idaho. The active fronts of these fires are outlined in red in this pair of photo-like images acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on July 19, 2007. The top image was taken at 12:25 p.m., Mountain Daylight Time, when the MODIS on NASA's Terra [ http://terra.nasa.gov/ ] satellite passed over head. The active parts of the Elk Mountain fire surround a dark brown oval of charred land. The fast-moving flames had consumed much of this area in the previous 24 hours. A MODIS image taken on the afternoon of July 18, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14396 ] reveals that the fire had been relatively small the previous day, and little land around the fire was charred. The Rowland fire, by contrast, was smaller on July 19 than it had been on July 18. At 2:05 p.m. on July 19, less than two hours after the top image was taken, the MODIS sensor aboard NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the lower image. In the two-hour period between images, winds and fire activity picked up substantially. By the time of the second image, the fires were racing through grass and sagebrush and pumping out dense plumes of smoke. The smoke obscures the burned land and the surrounding desert landscape. Strong winds were pulling the smoke north in long plumes that stretch over the green and gold Snake River Plain. The National Interagency Fire Center (NIFC) reported that both the Rowland and Elk Mountain fires exhibited extreme fire behavior, [ http://www.nifc.gov/fireinfo/glossary.html#E ] with fast-moving or unpredictable flames, and that it threatened structures and power lines. On July 20, the Rowland fire had burned 95,000 acres and was 15 percent contained, while the Elk Mountain fire had burned 160,000 acres (up from 25,000 acres the day before) and was 10 percent contained, said NIFC. The large images provided above are at MODIS' maximum resolution (level of detail) of 250 meters per pixel. They stretch south to include much of Nevada and Utah. Both the 12:25 and 2:05 images are available in a variety of resolutions from the MODIS Rapid Response System. Images courtesy Jeff Schmaltz,

Fires in Nevada
Title Fires in Nevada
Description Fire activity ramped up across the U.S. West near the end of the third week of July 2007. Dry thunderstorms (lightning and winds, but no rain) ignited hundreds of fires in a matter of days, and many of these became large blazes that raced through dry grass, sagebrush, and forests. This image of Nevada was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on July 18. Places where MODIS detected actively burning fire are outlined in red. Dark brown burn scars dot the buff-colored landscape, while thick smoke stretches north from the fires. Many of the fires are burning along the Interstate 80 corridor, the highway is dotted with small towns that fall along its path: Wells, Elko, Beowawe, Battle Mountain. A few of the largest fires are labeled. Ridgelines appear faint green, lightly covered in vegetation, while dry valleys in between are tan. Rare patches of intensely green vegetation are irrigated fields. South of Wells, Nevada, the forested Ruby Mountains are deep green.

Title Sierra Nevada Range, Mokelumne Wilderness
Description South of Lake Tahoe, in the Sierra Nevada mountain range in California, the boundaries of three national forests—Stanislaus, El Dorado, and Humboldt-Toiyabe—meet. At the intersection of these boundaries sits the Mokelumne Wilderness Area, [ http://www.fs.fed.us/r5/stanislaus/visitor/mokelumne.shtml ] which straddles the crest of the Sierra Nevada. On June 29, 2007, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image of the Mokelumne and surrounding forests. In this simulated true-color image, dark green indicates thick vegetation, pale green indicates sparse vegetation, dark blue indicates water, and beige and gray indicate bare ground. National Park boundaries appear in white. The terrain in the area is rugged, with steep mountain crags interspersed with occasional lakes with jagged contours. At high elevations, forests give way to alpine plants, and finally, to bare rock. A pale shoreline outlines Spicer Reservoir, near the bottom of the image, suggesting a dip in the lake's water level, consistent with warm, dry [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14393 ] conditions that predominated in the American West in the early summer of 2007. Not all national forests are wilderness area, many forests offer timber concessions. In Stanislaus National Forest, in the lower left corner of this image, tiny pale patches break the forest cover. In the high-resolution imagery, the precise geometric outlines of these patches are more obvious, such patterns are consistent with clear-cut logging.
