| Description |
This space radar image illustrates the recent rapid urban development occurring along the lower Colorado River at the Nevada/Arizona state line. Lake Mohave is the dark feature that occupies the river valley in the upper half of the image. The lake is actually a reservoir created behind Davis Dam, the bright white line spanning the river near the center of the image. The dam, completed in 1953, is used both for generating electric power and regulating the river's flow downstream. Straddling the river south of Davis Dam, shown in white and bright green, are the cities of Laughlin, Nevada (west of the river) and Bullhead City, Arizona (east of the river). The runway of the Laughlin, Bullhead City Airport is visible as a dark strip just east of Bullhead City. The area has experienced rapid growth associated with the gambling industry in Laughlin and on the Fort Mojave Indian Reservation to the south. The community of Riviera is the bright green area in a large bend of the river in the lower left part of the image. Complex drainage patterns and canyons are the dark lines seen throughout the image. Radar is a useful tool for studying these patterns because of the instrument's sensitivity to roughness, vegetation and subtle topographic differences. This image is 50 kilometers by 35 kilometers (31 miles by 22 miles) and is centered at 35.25 degrees north latitude, 114.67 degrees west longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations as follows: red is L-band, horizontally transmitted and received, green is L-band, horizontally transmitted and vertically received, and blue is C-band, horizontally transmitted and vertically received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR- C/X-SAR) on April 13, 1994, onboard the space shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Office of Mission to Planet Earth. ##### |

| Description |
This image shows a 40-kilometer (25-mile) wide strip of digital topographic data superimposed on an optical photograph of the western United States. Both images were acquired during the STS-68 flight in October 1994. The digital data were acquired by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture radar system, while the photograph was taken by the Space Shuttle astronauts. The view is looking to the east from above California's central valley (the dark area seen at the bottom of the image) across the snow-covered Sierra Nevada Mountains to the basin and range province of western Nevada. In the strip of topographic data, the different colors indicate elevation, with green being lowest and white being highest. The swath covers blue-colored Lake Tahoe on the left (north) and Mono Lake on the right. For comparison, the white lines indicate the 225- kilometer (140-mile) wide swath that will be mapped in a single pass by the Shuttle Radar Topography Mapper (SRTM) instrument, now scheduled to fly on the Space Shuttle in May 2000. The ability to cover a swath this wide will allow SRTM to completely map all the land surface between plus and minus 60 degrees latitude in a single 11-day flight. This is about 80% of Earth's total land area. SRTM, is a cooperative project between NASA and the Defense Mapping Agency of the U.S. Department of Defense that will be managed by the Jet Propulsion Laboratory for NASA's Office of Mission to Planet Earth. ##### |

| Description |
California's Garlock Fault, marking the northwestern boundary of the Mojave Desert, lies at the foot of the mountains, running from the lower right to the top center of this image, which was created with data from NASA's Shuttle Radar Topography Mission (SRTM), flown in February 2000. The data will be used by geologists studying fault dynamics and landforms resulting from active tectonics. These mountains are the southern end of the Sierra Nevada and the prominent canyon emerging at the lower right is Lone Tree Canyon. In the distance, the San Gabriel Mountains cut across from the left side of the image. At their base lies the San Andreas Fault which meets the Garlock Fault near the left edge at Tejon Pass. The dark linear feature running from lower right to upper left is State Highway 14 leading from the town of Mojave in the distance to Inyokern and the Owens Valley in the north. The lighter parallel lines are dirt roads related to power lines and the Los Angeles Aqueduct which run along the base of the mountains. This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota. This image was acquired by the Shuttle Radar Topography Mission (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 the Space Shuttle Endeavour in 1994. SRTM was 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, installed additional C-band and X-band antennas, 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) of the U.S. Department of Defense (DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, D.C. Size: Varies in a perspective view Location: 35.25 deg. North lat., 118.05 deg.

National Map Showing Habitat Suitability for Tamarisk Invasion |
| Abstract |
The spread of invasive species is one of the most daunting environmental, economic, and human-health problems facing the United States and the World today. It is one of several grand challenge environmental problems being addressed by NASA's Science Mission Directorate through a national application partnership with the US Geological Survey. NASA and USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species on Department of Interior and adjacent lands. The system provides a framework for using USGS's early detection and monitoring protocols and predictive models to process MODIS, ETM+, ASTER and commercial remote sensing data, to create on-demand, regional-scale assessments of invasive species likely habitats. Recent work on the Invasive Species Forecasting System (ISFS) project has shown the importance of remotely-sensed time-series data in geostatistical models for mapping the distribution of Tamarisk and other invasive plant species. This video shows the habitat suitability for a Tamarisk invasion in the continental United States. Red indicates areas that are highly suitable and yellow indicates areas which are less suitable. Texas, New Mexico, and Nevada are the most highly suitable states. Utah and Arizona have the next greatest risk. California, Arizona, Montana, Colorado, Oregon, Ohio, Wyoming, and Florida also have a significant risk. |

Lake Mead Shrinks! |
| Abstract |
Lake Mead reservoir is nestled between Arizona and Nevada and runs up to the Hoover Dam. The reservoir stores Colorado River water and supplies it to farms, homes and business in Southern Nevada, Arizona, southern California and northern Mexico. Scientists at NASA are releasing dramatic pictures of the dwindling water supplies in the drought-stricken western United States. According to the Bureau of Reclamation, the Colorado Basin is in its fourth year of drought and computer models project water levels will go down another 15 to 20 feet (4.6 to 6.1 m) by next year. Despite low water levels, The National Park Service says there is still plenty of water for recreation. The Landsat 7 satellite captured images of Lake Mead May 2000, and May 2003. The 2003 image clearly shows a shrinking lake. |

…
| Photo Description |
On 9 November 1962, an engine failure forced Jack McKay, a NASA research pilot, to make an emergency landing at Mud Lake, Nevada, in the second X-15 (56-6671), its landing gear collapsed and the X-15 flipped over on its back. McKay was promptly rescued by an Air Force medical team standing by near the launch site, and eventually recovered to fly the X-15 again. But his injuries, more serious than at first thought, eventually forced his retirement from NASA. The aircraft was sent back to the manufacturer, where it underwent extensive repairs and modifications. It returned to Edwards in February 1964 as the X-15A-2, with a longer fuselage (52 ft 5 in) and external fuel tanks. |
| Project Description |
The basic X-15 was a rocket-powered aircraft 50 ft long with a wingspan of 22 ft. It was a missile-shaped vehicle with an unusual wedge-shaped vertical tail, thin stubby wings, and unique side fairings that extended along the side of the fuselage. The X-15 weighed about 14,000 lb empty and approximately 34,000 lb at launch. The XLR-99 rocket engine, manufactured by Thiokol Chemical Corp., was pilot controlled and was capable of developing 57,000 lb of thrust. North American Aviation built three X-15 aircraft for the program. The X-15 research aircraft was developed to provide in-flight information and data on aerodynamics, structures, flight controls, and the physiological aspects of high-speed, high-altitude flight. A follow-on program used the aircraft as a testbed to carry various scientific experiments beyond the Earth's atmosphere on a repeated basis. For flight in the dense air of the usable atmosphere, the X-15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and movable horizontal stabilizers to control pitch when moving in synchronization or roll when moved differentially. For flight in the thin air outside of the appreciable Earth's atmosphere, the X-15 used a reaction control system. Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control. Those on the wings provided roll control. Because of the large fuel consumption, the X-15 was air launched from a B-52 aircraft at 45,000 ft and a speed of about 500 mph. Depending on the mission, the rocket engine provided thrust for the first 80 to 120 sec of flight. The remainder of the normal 10 to 11 min. flight was powerless and ended with a 200-mph glide landing. Generally, one of two types of X-15 flight profiles was used, a high-altitude flight plan that called for the pilot to maintain a steep rate of climb, or a speed profile that called for the pilot to push over and maintain a level altitude. The X-15 was flown over a period of nearly 10 years--June 1959 to Oct. 1968--and set the world's unofficial speed and altitude records of 4,520 mph (Mach 6.7) and 354,200 ft in a program to investigate all aspects of manned hypersonic flight. Information gained from the highly successful X-15 program contributed to the development of the Mercury, Gemini, and Apollo manned spaceflight programs, and also the Space Shuttle program. The X-15s made a total of 199 flights, and were manufactured by North American Aviation. X-15-1, serial number 56-6670, is now located at the National Air and Space Museum, Washington DC. North American X-15A-2, serial number 56-6671, is at the United States Air Force Museum, Wright-Patterson AFB, Ohio. The X-15-3, serial number 56-6672, crashed on 15 November 1967, resulting in the death of Maj. Michael J. Adams. |

Blizzards in the Western United States |
| Description |
A series of heavy winter storms pummeled parts of the western United States between December 24, 2003, and January 3, 2004, blanketing the region with deep snow. Salt Lake City, Utah, reported more than six feet of snow, according to news reports. The blizzards that rolled through California, Nevada, Oregon, Washington, Idaho, Utah, Montana, Wyoming, and Colorado closed roads, knocked out power, and claimed at least two lives in subsequent avalanches. These Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) images, taken on January 5, 2004, by the Terra [ http://terra.nasa.gov/ ] satellite, show the extent of the snowfall from California in the west to the Dakotas, Nebraska, and Colorado in the east. The Great Salt Lake is the two-toned body of water in the center of the images. In the top image, shown in true color, only a sliver of green land west of the Sierra Nevada Mountains can be see on the left side of the image?clouds and snow obscure the rest of the landscape. The bottom image shows the same scene in false color. Here, snow and ice are dark red and orange, while clouds are white and peach. Water is black. The false color image helps differentiate between cloud cover and snow and ice on the ground. The high resolution images provided above are at 500 meters per pixel.

| Title |
Charleston Fire, Northern Nevada |
| Description |
In northeastern Nevada, a 20,000-acre fire was racing through sagebrush, grass, and juniper on August 16, 2006. According to the National Interagency Fire Center, [ http://www.nifc.gov/information.html ] a power line, residences, and grazing allotments were being threatened by the Charleston Fire. The fire was exhibiting extreme behavior according to the August 17 report. This pair of images of the Charleston Fire, burning in the area between Nevada's Matterhorn and the Marys River, was captured on August 16 by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite. The photo-like, "natural-color" image on top shows places where MODIS detected active fire outlined in red. Thick smoke pours northeastward into Idaho. The bottom image has been enhanced using MODIS' observations of shortwave and near-infrared light to penetrate the smoke, to emphasize extremely hot areas (bright pink), and to distinguish burned vegetation (brick red) from unburned vegetation (bright green). In this kind of false-color image, the bright pink glow inside some of the active-fire perimeters often indicates open flame. According to the Western Great Basin Coordination Center of the National Interagency Fire Center, the region was primed for big fires in summer 2006 because of poor snowfall over the winter. A prolific grass crop from 2005, which normally would have been flattened and compacted by winter's heavy snow, remained standing across grasslands in spring 2006. In addition, a wet spring produced luxuriant new growth, which dried as the summer progressed. The standing grass from 2005 combined with the abundant early-2006 growth created a dangerously high load of fuel for summer fires. In July, the agency issued a fuel and fire behavior advisory, [ http://gacc.nifc.gov/wgbc/safetywarning/FireAdvisory_GB-05Jul06%5b1%5d.pdf ] warning that the accumulation of such large amounts of "fine fuels" like grass had increased the risk of intense, severe, and rapidly spreading fires across much of the Western Great Basin, including northern Nevada. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response System provides twice-daily images of the entire western United States at additional resolutions.

Cloudy winter in Mexico and the Southern United States |
| Description |
February was a cloudy and, in some places, a rainy month for much of the southern United States and Mexico. Heavy rains flooded southern California, Nevada, Utah and Arizona. This image hints at patterns of cloud cover during February. The image is a measurement of outgoing longwave radiation, the heat emitted by the Earth's surface. Clouds are cooler than land, so outgoing longwave radiation is less intense where there are clouds. The above image shows anomalies—where February 2005 differed from average values measured in February 1979-1995. Regions where there were more clouds than normal are blue, while areas with fewer clouds are red. The blue regions seen here confirm the days of rain that southern North America experienced in February. This image was derived from measurements made by the TIROS Operational Vertical Sounder (TOVS) onboard the NOAA-POES satellite series.

| 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.

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 |
| 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.

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.

Snow Across the Western United States |
| Description |
The Sunday after Thanksgiving is traditionally one of the busiest travel days of the year in the United States as people return home from the four-day weekend. Sunday, November 28, 2004, was no exception, but this year, Mother Nature snarled traffic across a large swath of the west with an intense snow storm. The storm dumped up to 24 inches (0.6 meters) of snow on the mountains of southern Utah, and blanketed the surrounding states. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image the following day, on November 29, after the clouds moved out. The storm's path is clearly visible in this image: a track of white extends from southeastern Oregon and the Sierra Nevada Mountains in California to Colorado and New Mexico in the east. The National Weather Service reports that the storm moved east across the Plains States of Nebraska, Kansas, Oklahoma, Texas, Missouri, and Iowa on November 29 and November 30. The snow highlights some interesting features of the Western United States that might not otherwise be obvious in satellite imagery. Sandwiched between the straight diagonal line of the Sierra Nevada Mountains in the west (the straight edge of the snow) and the Rocky Mountains in Central Utah in the east is the Great Basin Desert. This high desert basin covers a heart-shaped region of southern Oregon, Nevada, Utah, and southern Idaho and is clearly outlined in snow. Hemmed between two large mountain ranges that trap moisture from the east and the west, it is the United States' largest desert. It receives on average 7-12 inches of precipitation every year. The water that does fall in the region drains to interior, closed basins instead of the ocean, giving the region its name. The Great Basin Desert is made up of a series of mostly north-south running mountain ranges and valleys that give the land a wrinkled, wash-board appearance, particularly in Nevada. The snow highlights elevation change elsewhere in the image. The imposing Rocky Mountains appear slightly darker than the valleys around them, and the peaks and high plateaus in the south are covered in snow while the pink desert lowlands remain bare. On the right edge of the image, the flat plains of eastern Wyoming and Colorado are an even, uninterrupted white.

Fires Scorch Oregon |
| Description |
Throughout the western United States, wildfire danger is high and expected to remain so, with the peak of the annual fire season not expected until August. The total number of acres already burned is more than triple the ten-year average. National attention has shifted as one state after another experiences a flare up of forest fires?from California, to Colorado, to Arizona. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from July 15, 2002, places Oregon in the spotlight, with numerous large fires (red dots) scattered throughout the state. The northernmost fire is the Eyerly Fire, which is greater than 17,000 acres and only 40 percent contained. The four large fires dominating the south-central part of the state are the (north-south) Silver, Toolbox, Winter, and Grizzly Complex Fires. The large outline of those fires indicates that MODIS has detected active fire in numerous adjacent 1-km by 1-km pixels, which suggests fires are burning actively on many fronts. Reports from the National Interagency Fire Center state that none of those four fires is more than 5 percent contained. To the south, a large complex of wildfires burning on the California-Nevada border south of Lake Tahoe is proving difficult to contain due to high winds and steep terrain. The Gate Complex Fire is threatening at least 275 structures, and power and water have been lost in some areas as fires burned through power lines. The fire is greater than 10,000 acres and still growing. Please note that the high-resolution scene provided here is 500 meters per pixel.

Winter Storms Lash the Western United States |
| Description |
Between late December 2004 and mid-January 2005, many places in the U.S. West received snowfall daily. The area around Lake Tahoe in the Sierra Nevada Mountains, for example, received snow every day from December 24 through January 11, and had accumulations around 19 feet. The rapid accumulation of such large amounts of snow increases avalanche risk, and land managers at ski resorts and state and national parks have been busy assessing snow pack stability and setting off explosives at avalanche- prone locations to release snow and to test the stability of the snow layers. This pair of images uses visible and short-wave infrared observations form the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors on NASA?s Terra and Aqua satellites to show the widespread snow cover in California, Nevada, and Utah on January 12, 2005 (top), compared to December 23, 2004 (bottom). Snow appears bright blue, water appears deep blue, vegetation appears bright green, and clouds appear white. In addition to the widespread blanket of snow stretching all the way across the January 12 image, a few areas of standing water appear more clearly than in the December image. Water on the ground increased in the northern end of the California Central Valley, as well as in the salt pans to the west-southwest of the Great Salt Lake. The high-resolution image provided above is the January 12 image at a spatial resolution of 500 meters per pixel. The MODIS Rapid Response System provides both images at additional resolutions and color combinations: January 12, 2005, and December 23, 2004.

Winter Storms Lash the Western United States |

Heavy snow covered most of the western United States on January 12, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. Much of the snow has fallen in a series of storms that started at the end of December. Between December 27 and January 3, 12 to 14 feet (3.7 to 4.3 meters) of snow fell on the Sierra Nevada around Lake Tahoe, and additional snow has fallen since that time. Heavy snow has also fallen on the mountains of Nevada, Utah, and Arizona. As this image shows, the snow is not confined to the mountains. The valleys are also draped in white. Tucked between two mountain ranges, Cache Valley in northern Utah received up to 20 inches (0.51 m) of snow between January 8 and January 12?enough snow to cause trees and power lines to topple and roofs to bow. Not all of the white seen in the true-color image (top) can be attributed to snow. Clouds also cover parts of the region. The false-color image helps distinguish between cloud and snow. Created using visible and infrared wavelengths of energy, the image shows snow and ice as a turquoise blue and warmer water clouds as white. High ice clouds, such as those covering southwestern Colorado, are also turquoise. Vegetation is bright green, and water is dark blue and black. Because water stands out more clearly in the false-color image, floods are also visible. In this image, water has accumulated on the Bonneville Salt Flats west of the Great Salt Lake in northern Utah. Formerly part of a massive lake bed, the Salt Flats consist of a broad, flat plain that is crusted with a deposit of salty minerals and devoid of vegetation. Winter precipitation typically covers the plain with a light layer of water that evaporates in the spring and summer. The ground is bare in the southwest, where the precipitation has fallen as rain. Devastating floods have raged along the rivers of southwestern Utah, northwestern Arizona, and southeastern Nevada, destroying bridges, roads, and homes. In southern California, the rain has triggered widespread floods and a deadly mudslide. Destructive though the floods may be, they are not clearly visible in this image. Despite the problems the storms have caused, the snowfall is a boon to the parched west, where a prolonged drought has drained reservoirs over the past four years. In the western United States, as in many semi-arid regions, the water supply depends on snow melt flowing down from the mountains during the summer. Currently, the snowpack water content (the amount of water stored in mountain snow) is 150 percent of normal in much of the Southwest, reports a scientist from the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center. [ http://www.noaanews.noaa.gov/stories2005/s2364.htm ], The snow could start to relieve the drought as long as a warm spring does not melt the snow too early.

In this image, water has accumulated on the Bonneville Salt Flats west of the Great Salt Lake in northern Utah. Formerly part of a massive lake bed, the Salt Flats consist of a broad, flat plain that is crusted with a deposit of salty minerals and devoid of vegetation. Winter precipitation typically covers the plain with a light layer of water that evaporates in the spring and summer. The ground is bare in the southwest, where the precipitation has fallen as rain. Devastating floods have raged along the rivers of southwestern Utah, northwestern Arizona, and southeastern Nevada, destroying bridges, roads, and homes. In southern California, the rain has triggered widespread floods and a deadly mudslide. Destructive though the floods may be, they are not clearly visible in this image. Despite the problems the storms have caused, the snowfall is a boon to the parched west, where a prolonged drought has drained reservoirs over the past four years. In the western United States, as in many semi-arid regions, the water supply depends on snow melt flowing down from the mountains during the summer. Currently, the snowpack water content (the amount of water stored in mountain snow) is 150 percent of normal in much of the Southwest, reports a scientist from the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center. [ http://www.noaanews.noaa.gov/stories2005/s2364.htm ], The snow could start to relieve the drought as long as a warm spring does not melt the snow too early.

X-15 #2 on lakebed after engine failure forced pilot Jack McKay to make an emergency landing at Mud |
| Description |
On 9 November 1962, an engine failure forced Jack McKay, a NASA research pilot, to make an emergency landing at Mud Lake, Nevada, in the second X-15 (56-6671), its landing gear collapsed and the X-15 flipped over on its back. McKay was promptly rescued by an Air Force medical team standing by near the launch site, and eventually recovered to fly the X-15 again. But his injuries, more serious than at first thought, eventually forced his retirement from NASA. The aircraft was sent back to the manufacturer, where it underwent extensive repairs and modifications. It returned to Edwards in February 1964 as the X-15A-2, with a longer fuselage (52 ft 5 in) and external fuel tanks. The basic X-15 was a rocket-powered aircraft 50 ft long with a wingspan of 22 ft. It was a missile-shaped vehicle with an unusual wedge-shaped vertical tail, thin stubby wings, and unique side fairings that extended along the side of the fuselage. The X-15 weighed about 14,000 lb empty and approximately 34,000 lb at launch. The XLR-99 rocket engine, manufactured by Thiokol Chemical Corp., was pilot controlled and was capable of developing 57,000 lb of thrust. North American Aviation built three X-15 aircraft for the program. The X-15 research aircraft was developed to provide in-flight information and data on aerodynamics, structures, flight controls, and the physiological aspects of high-speed, high-altitude flight. A follow-on program used the aircraft as a testbed to carry various scientific experiments beyond the Earth's atmosphere on a repeated basis. For flight in the dense air of the usable atmosphere, the X-15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and movable horizontal stabilizers to control pitch when moving in synchronization or roll when moved differentially. For flight in the thin air outside of the appreciable Earth's atmosphere, the X-15 used a reaction control system. Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control. Those on the wings provided roll control. Because of the large fuel consumption, the X-15 was air launched from a B-52 aircraft at 45,000 ft and a speed of about 500 mph. Depending on the mission, the rocket engine provided thrust for the first 80 to 120 sec of flight. The remainder of the normal 10 to 11 min. flight was powerless and ended with a 200-mph glide landing. Generally, one of two types of X-15 flight profiles was used, a high-altitude flight plan that called for the pilot to maintain a steep rate of climb, or a speed profile that called for the pilot to push over and maintain a level altitude. The X-15 was flown over a period of nearly 10 years--June 1959 to Oct. 1968--and set the world's unofficial speed and altitude records of 4,520 mph (Mach 6.7) and 354,200 ft in a program to investigate all aspects of manned hypersonic flight. Information gained from the highly successful X-15 program contributed to the development, of the Mercury, Gemini, and Apollo manned spaceflight programs, and also the Space Shuttle program. The X-15s made a total of 199 flights, and were manufactured by North American Aviation. X-15-1, serial number 56-6670, is now located at the National Air and Space Museum, Washington DC. North American X-15A-2, serial number 56-6671, is at the United States Air Force Museum, Wright-Patterson AFB, Ohio. The X-15-3, serial number 56-6672, crashed on 15 November 1967, resulting in the death of Maj. Michael J. Adams. |

X-15 #3 in flight (USAF Photo) |
| Description |
This U.S. Air Force photo shows the X-15 ship #3 (56-6672) in flight over the desert in the 1960s. Ship #3 made 65 flights during the program, attaining a top speed of Mach 5.65 and a maximum altitude of 354,200 feet. Only 10 of the 12 X-15 pilots flew Ship #3, and only eight of them earned their astronaut wings during the program. Robert White, Joseph Walker, Robert Rushworth, John "Jack" McKay, Joseph Engle, William "Pete" Knight, William Dana, and Michael Adams all earned their astronaut wings in Ship #3. Neil Armstrong and Milton Thompson also flew Ship #3. In fact, Armstrong piloted Ship #3 on its first flight, on 20 December 1961. On 15 November 1967, Ship #3 was launched over Delamar Lake, Nevada with Maj. Michael J. Adams at the controls. The vehicle soon reached a speed of Mach 5.2, and a peak altitude of 266,000 feet. During the climb, an electrical disturbance degraded the aircraft's controllability. Ship #3 began a slow drift in heading, which soon became a spin. Adams radioed that the X-15 "seems squirrelly" and then said "I'm in a spin." Through some combination of pilot technique and basic aerodynamic stability, Adams recovered from the spin and entered an inverted Mach 4.7 dive. As the X-15 plummeted into the increasingly thicker atmosphere, the Honeywell adaptive flight control system caused the vehicle to begin oscillating. As the pitching motion increased, aerodynamic forces finally broke the aircraft into several major pieces. Adams was killed when the forward fuselage impacted the desert. This was the only fatal accident during the entire X-15 program. The X-15 was a rocket-powered aircraft 50 ft long with a wingspan of 22 ft. It was a missile-shaped vehicle with an unusual wedge-shaped vertical tail, thin stubby wings, and unique side fairings that extended along the side of the fuselage.

Parts of the crashed X-15-3, serial number 56-6672, recovered in 1992 by Peter Merlin and Tony Moore (The X-Hunters) are on display at the Air Force Flight Test Center Museum at Edwards. The canopy from Ship #3, recovered during the original search in 1967, is displayed at the San Diego Aerospace Museum, San Diego, California. |
