| Description |
One hundred eighty-seven homes were destroyed by the Freeway Fire in Southern California in mid-November 2008. Driven by Santa Ana winds, the fire exploded out of the Chino Hills into communities at the foothills of the mountains. More than 30,000 acres were scorched by the fire. This natural-color image of the burned area was captured by the Advanced Land Imager (ALI) on NASA's Earth Observing-1 satellite on November 18, 2008. The top image shows the Chino Hills north of Riverside Freeway and west of Chino Valley Freeway, a mostly undeveloped area that encompasses Chino Hills State Park. Small cities and residential areas encircle the mountains. The burned area is charcoal, and it stretches across most of the Chino Hills. The lower image is a detailed view of the edge of the burned area in northwestern Yorba Linda. The fire crossed Telegraph Canyon and made forays southwestward into neighborhoods. One arm of the fire encircled Carbon Canyon Regional Park. Southeast of the Riverside Freeway (shown in the large image), is a part of Chino Hills State Park called the Coal Canyon area. The area has a dull greenish-brown color that is typical for the dry woodland/chaparral ecosystems native to the area. (In this part of California, bright green vegetation is the product of irrigation, for example, golf courses and lawns.) The Coal Canyon area was added to China Hills State Park in 2000, and it was the only part of the 14,000-acre park that was not burned, according to local news reports.

| Description |
The hand-held hydrogen fire imager was originally developed to "see" the invisible flames of hydrogen and alcohol fires. It has also proven helpful for firefighters who fight conventional fires by allowing them to see through dense smoke, locate the seat of the fire, and image smoldering embers. NASA and Lockheed Martin engineers at Stennis Space Center invented the fire imager and invited fire department and industry representatives from the Mississippi Gulf Coast to a demonstration. Stennis Space Center's fire department set fire to an abandoned building on the test site to demonstrate how the imager works on visible fires. |

01/08/10
| Description |
On Jan. 7, 1610, Galileo Galilei's improvements to the telescope enabled humanity to see Jupiter's four largest moons for the first time. Io, Europa, Ganymede and Callisto--the so-called Galilean satellites--were seen by the Long Range Reconnaissance Imager on the New Horizons spacecraft during its flyby of Jupiter in late February 2007. The images have been scaled to represent the true relative sizes of the four moons and are arranged in their order from Jupiter. Io is notable for its active volcanism, which New Horizons studied extensively. On the other hand, Europa's smooth, icy surface likely conceals an ocean of liquid water. New Horizons obtained data on Europa's surface composition and imaged subtle surface features, and analysis of these data may provide new information about the ocean and the icy shell that covers it. New Horizons spied Ganymede from 2.2 million miles away. Ganymede, the largest moon in the solar system, has a dirty ice surface cut by fractures and peppered by impact craters. New Horizons' infrared observations may provide insight into the composition of the moon's surface and interior. Scientists are using the infrared spectra New Horizons gathered of Callisto's ancient, cratered surface to calibrate spectral analysis techniques that will help them to understand the surfaces of Pluto and its moon Charon when New Horizons passes them in 2015.

Europa's Broken Ice
Jupiter's moon Europa, as se
…
| Description |
Jupiter's moon Europa, as seen in this image taken June 27, 1996 by NASA's Galileo spacecraft, displays features in some areas resembling ice floes seen in Earth's polar seas. Europa, about the size of Earth's moon, has an icy crust that has been severely fractured, as indicated by the dark linear, curved, and wedged- shaped bands seen here. These fractures have broken the crust into plates as large as 30 kilometers (18.5 miles) across. Areas between the plates are filled with material that was probably icy slush contaminated with rocky debris. Some individual plates were separated and rotated into new positions. Europa's density indicates that it has a shell of water ice as thick as 100 kilometers (about 60 miles), parts of which could be liquid. Currently, water ice could extend from the surface down to the rocky interior, but the features seen in this image suggest that motion of the disrupted icy plates was lubricated by soft ice or liquid water below the surface at the time of disruption. This image covers part of the equatorial zone of Europa and was taken from a distance of 156,000 kilometers (about 96,300 miles) by the solid-state imager camera on the Galileo spacecraft. North is to the right and the sun is nearly directly overhead. The area shown is about 360 by 770 kilometers (220-by-475 miles or about the size of Nebraska), and the smallest visible feature is about 1.6 kilometers (1 mile) across. |

| Full Description |
This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and after touchdown. The camera was funded by NASA. The almost four-hour-long operation of the camera is shown in less than five minutes. That's 40 times the actual speed up to landing and 100 times the actual speed thereafter. The first part of the movie shows how Titan looked to the camera as it acquired more and more images during the probe's descent. Each image has a small field of view, and dozens of images were made into mosaics of the whole scene. The scientists analyzed Huygens' speed, direction of motion, rotation and swinging during the descent. The movie includes sidebar graphics that show: * (Lower left corner) Huygens' trajectory views from the south, a scale bar for comparison to the height of Mount Everest, colored arrows that point to the sun and to the Cassini orbiter. * (Top left corner) A close-up view of the Huygens probe highlighting large and unexpected parachute movements, a scale bar for comparison to human height. * (Lower right corner) A compass that shows the changing direction of view as Huygens rotates, along with the relative positions of the sun and Cassini. * (Upper right corner) A clock that shows Universal Time for Jan. 14, 2005 (Universal Time is 7 hours ahead of Pacific Daylight Time). Above the clock, events are listed in mission time, which starts with the deployment of the first of the three parachutes. Sounds from a left speaker trace Huygens' motion, with tones changing with rotational speed and the tilt of the parachute. There also are clicks that clock the rotational counter, as well as sounds for the probe's heat shield hitting Titan's atmosphere, parachute deployments, heat shield release, jettison of the camera cover and touchdown. Sounds from a right speaker go with the Descent Imager/Spectral Radiometer activity. There's a continuous tone that represents the strength of Huygens' signal to Cassini. Then there are 13 different chimes - one for each of instrument's 13 different science parts - that keep time with flashing-white-dot exposure counters. During its descent, the Descent Imager/Spectral Radiometer took 3,500 exposures. The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C.

| Full Description |
This movie was built with data collected during the 147-minute plunge through Titan's thick orange-brown atmosphere to a soft sandy riverbed by the European Space Agency's Huygens Descent Imager/Spectral Radiometer on Jan. 14, 2005, In 4 minutes and 40 seconds, the movie shows what the probe 'saw' within the few hours of the descent and the landing. On approach, Titan appeared as just a little disk in the sky among the stars, but after landing, the probe's camera resolved little grains of sand millions of times smaller than Titan. At first, the Huygens camera just saw fog over the distant surface. The fog started to clear only at about 60 kilometers (37 miles) altitude, making it possible to resolve surface features as large as 100 meters (328 feet). Only after landing could the probe's camera resolve the little grains of sand. The movie provides a glimpse of such a huge change of scale. A music-only version of the video is available at: http://photojournal.jpl.nasa.gov/catalog/PIA08118. The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif.

| Full Description |
This map illustrates the planned imaging coverage for the Descent Imager/Spectral Radiometer, onboard the European Space Agency's Huygens probe during the probe's descent toward Titan's surface on Jan. 14, 2005. The Descent Imager/Spectral Radiometer is one of two NASA instruments on the probe. The colored lines delineate regions that will be imaged at different resolutions as the probe descends. The site where Huygens is predicted to land is marked with a yellow dot. This area is in a boundary between dark and bright regions. This map was made from the images taken by the Cassini spacecraft cameras on Oct. 26, 2004, at image scales of 4 to 6 kilometers (2.5 to 3.7 miles) per pixel. The images were obtained using a narrow band filter centered at 938 nanometers - a near-infrared wavelength (invisible to the human eye) at which light can penetrate Titan's atmosphere to reach the surface and return through the atmosphere to be detected by the camera. The images have been processed to enhance surface details. Only brightness variations on Titan's surface are seen, the illumination is such that there is no shading due to topographic variations. For about two hours, the probe will fall by parachute from an altitude of 160 kilometers (99 miles) to Titan's surface. During the descent the Descent Imager/Spectral Radiometer and five other science instruments will send data about the moon's atmosphere and surface back to the Cassini spacecraft for relay to Earth. The Descent Imager/Spectral Radiometer will take pictures as the probe slowly spins, and some of these will be made into panoramic views of Titan's surface. The first map (PIA06172) shows expected coverage by the Descent Imager/Spectral Radiometer side-looking imager and two downward-looking imagers - one providing medium-resolution and the other high-resolution coverage. The planned coverage by the medium- and high-resolution imagers is the subject of this map (PIA06173). The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C.

First Color View of Titan's Surface |
| Full Description |
This image was returned yesterday, January 14, 2005, by the European Space Agency's Huygens probe during its successful descent to land on Titan. This is the colored view, following processing to add reflection spectra data, and gives a better indication of the actual color of the surface. Initially thought to be rocks or ice blocks, they are more pebble-sized. The two rock-like objects just below the middle of the image are about 15 centimeters (about 6 inches) (left) and 4 centimeters (about 1.5 inches) (center) across respectively, at a distance of about 85 centimeters (about 33 inches) from Huygens. The surface is darker than originally expected, consisting of a mixture of water and hydrocarbon ice. There is also evidence of erosion at the base of these objects, indicating possible fluvial activity. The image was taken with the Descent Imager/Spectral Radiometer, one of two NASA instruments on the probe.

Expected Footprints of 36-Image Panoramas from Huygens Camera |
| Full Description |
This map of a portion of the surface of Saturn's moon Titan shows predictions for the areas that will be covered by selected combinations of images anticipated from the camera on the Huygens probe as it descends through Titan's atmosphere on Jan. 14, 2005. The map is made from data acquired by the visual and infrared mapping spectrometer aboard the Cassini orbiter during the orbiter's flyby of Titan in October 2004. Cassini released the Huygens probe in December 2004. The octagons indicate anticipated fields of view of panoramic mosaics of images taken by Huygens' descent imager and spectral radiometer instrument as the probe reaches certain altitudes during its descent. This map shows the footprints for mosaics to be assembled from 36 individual images at each altitude, with the field of view cut off at 75 degrees from straight down although the actual images will extend all the way to the hazy horizon. Each mosaic made this way will be about 1,300 by 1,300 pixels. The largest octagon (in red) is about 1,120 kilometers (696 miles) across and represents the field of view for the mosaic of images taken at an altitude of 150 kilometers (93 miles). From that height, individual pixels in the center of the image will be about 150 meters (492 feet) across, though haze between the ground and the camera at that height will likely degrade the resolution in those images. The progressively smaller octagons are the anticipated fields of view from altitudes of 90 kilometers (60 miles), 50 kilometers (30 miles) and 30 kilometers (19 miles). In all, the camera is expected to acquire panoramic mosaics at a total of 20 different altitudes from 150 kilometers (93 miles) down to about 3 kilometers (2 miles). The pixel size in the mosaic from 3 kilometers high will be about 3 meters (10 feet) across. In addition, the camera is expected to obtain individual images down to an altitude of about 200 meters (656 feet) with pixel size as small as 20 centimeters (8 inches). The location of the anticipated landing site is based on modeling of Titan's winds, and the actual landing site will be different if the actual winds experienced by Huygens during descent differ from this model. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

This composite was produced from images returned yesterday, January 14, 2005, by the European Space Agency's Huygens probe during its successful descent to land on Titan. It shows a full 360-degree view around Huygens. The left-hand side, behind Huygens, shows a boundary between light and dark areas. The white streaks seen near this boundary could be ground 'fog,' as they were not immediately visible from higher altitudes. As the probe descended, it drifted over a plateau (center of image) and was heading towards its landing site in a dark area (right). From the drift of the probe, the wind speed has been estimated at around 6-7 kilometers (about 4 miles) per hour. These images were taken from an altitude of about 8 kilometers ( about 5 miles) with a resolution of about 20 meters (about 65 feet) per pixel. The images were taken by the Descent Imager/Spectral Radiometer, one of two NASA instruments on the probe.

| Full Description |
This short animation is made up from a sequence of images taken by the Descent Imager/Spectral Radiometer (DISR) instrument on board ESA's Huygens probe, during its successful descent to Titan on Jan. 14, 2005. It shows what a passenger riding on Huygens would have seen. The sequence starts from an altitude of 152 kilometers (about 95 miles) and initially only shows a hazy view looking into thick cloud. As the probe descends, ground features can be discerned and Huygens emerges from the clouds at around 30 kilometers (about 19 miles) altitude. The ground features seem to rotate as Huygens spins slowly under its parachute. The DISR consists of a downward-looking High Resolution Imager (HRI), a Medium Resolution Imager (MRI), which looks out at an angle, and a Side Looking Imager (SLI). For this animation, most images used were captured by the HRI and MRI. Once on the ground, the final landing scene was captured by the SLI.

Huygens Titan Mosaic #1 |
| Full Description |
This stereographic projection of Descent Imager/Spectral Radiometer images from the European Space Agency's Huygens probe combines 60 images in 31 triplets, projected from a height of 3,000 meters (9,843 feet) above the black 'lakebed' surface. The bright area to the north (top of the image) and west is higher than the rest of the terrain, and covered in dark lines that appear to be drainage channels. The images were then stitched together using one of several projection algorithms (in this case 'stereographic') to produce a full mosaic. The images used to construct this mosaic were taken on Jan. 14, 2005. The Descent Imager/Spectral Radiometer is one of two NASA-funded instruments on the probe.

| Full Description |
This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and after touchdown. The camera was funded by NASA. The almost four-hour-long operation of the camera is shown in less than five minutes. That's 40 times the actual speed up to landing and 100 times the actual speed thereafter. The first part of the movie shows how Titan looked to the camera as it acquired more and more images during the probe's descent. Each image has a small field of view, and dozens of images were made into mosaics of the whole scene. The scientists analyzed Huygens' speed, direction of motion, rotation and swinging during the descent. The movie includes sidebar graphics that show: * (Lower left corner) Huygens' trajectory views from the south, a scale bar for comparison to the height of Mount Everest, colored arrows that point to the sun and to the Cassini orbiter. * (Top left corner) A close-up view of the Huygens probe highlighting large and unexpected parachute movements, a scale bar for comparison to human height. * (Lower right corner) A compass that shows the changing direction of view as Huygens rotates, along with the relative positions of the sun and Cassini. * (Upper right corner) A clock that shows Universal Time for Jan. 14, 2005 (Universal Time is 7 hours ahead of Pacific Daylight Time). Above the clock, events are listed in mission time, which starts with the deployment of the first of the three parachutes. Sounds from a left speaker trace Huygens' motion, with tones changing with rotational speed and the tilt of the parachute. There also are clicks that clock the rotational counter, as well as sounds for the probe's heat shield hitting Titan's atmosphere, parachute deployments, heat shield release, jettison of the camera cover and touchdown. Sounds from a right speaker go with the Descent Imager/Spectral Radiometer activity. There's a continuous tone that represents the strength of Huygens' signal to Cassini. Then there are 13 different chimes - one for each of instrument's 13 different science parts - that keep time with flashing-white-dot exposure counters. During its descent, the Descent Imager/Spectral Radiometer took 3,500 exposures. The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer.

Pinpointing Huygens Landing Site |
| Full Description |
The Cassini spacecraft carried the European Space Agency's Huygens probe to Saturn and released it in December 2004. The probe landed on Titan Jan. 14, 2005, acquiring a set of images using the descent imager/spectral radiometer camera as it parachuted to the surface. As Cassini continued to orbit Saturn, its imaging science subsystem and visual and infrared mapping spectrometer mapped the region where the Huygens probe landed. On Friday, Oct. 28, 2005, Cassini's radar instrument provided the highest resolution orbital data yet of this area. The two images shown here tell the story. On the left, in color, is a composite of the imaging camera and infrared data (red areas are brighter and blue darker, as seen in infrared). On the right is the synthetic aperture radar image. The Huygens descent images are shown inset on the left image and outlined in yellow on the right. The magenta cross in both images shows the best estimate of the actual Huygens landing site. This is a preliminary result, based on the best information available at the present time. In the left image, the brighter areas seen by the Huygens camera correspond to the large area depicted in red and yellow. On closer inspection, bright features within the Huygens mosaic seem to correspond to smaller features in the map composed of data from the visual and infrared spectrometer and imaging camera. On the right, the correspondence is less clear. In radar images bright features are usually rougher, so one would not necessarily expect an obvious connection. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C.

View from Titan's Surface |
| Full Description |
Images from the European Space Agency's Huygens probe descent imager/spectral radiometer side-looking imager and from the medium resolution imager, acquired after landing, were merged to produce this image. The horizon's position implies a pitch of the imager/spectral radiometer, nose-upward, by 1 to 2 degrees with no measurable roll. "Stones" in the foreground are 4 to 6 inches (10 to 15 centimeters) in size, presumably made of water ice, and these lie on a darker, finer-grained substrate. A region with a relatively low number of rocks lies between clusters of rocks in the foreground and the background and matches the general orientation of channel-like features in the panorama of Titan's Surface #2. The scene evokes the possibility of a dry lakebed. The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif.

| Full Description |
This complex area of hilly terrain and erosional channels is located atop Xanadu, the continent-sized region on Saturn's moon Titan. The image was captured by the Cassini Titan Radar Mapper on April 30, 2006. It shows details as small as 350 meters (1148 feet). Each side of the picture covers 200 kilometers (124 miles). Chains of hills or mountains are located near the bottom of the image, appearing bright on their north side (toward the top in this image). Extending further north is a drainage region where liquids flowed, eroding the presumably water-ice bedrock of Xanadu. Careful inspection reveals a series of faint drainage channels, some of which appear to empty into the dark region near the top of the image. Liquid methane might be fed from springs within Xanadu or by occasional rainfall suspected to occur on Titan. There is evidence for this rainfall in images taken by the Descent Imager/ Spectral Radiometer camera on the Huygens probe as it landed, well to the west of this area, on January 14, 2005 (see Water Ice and Methane Springs on Titan).

The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The descent imager/spectral radiometer team is based at the University of Arizona, Tucson. For more information about the Cassini-Huygens mission visit http://saturn.jpl.nasa.gov .

Magnified Mars

Magnified Mars |
| description |
This magnified look at the martian soil near the Mars Exploration Rover Opportunity's landing site, Meridiani Planum, shows coarse grains sprinkled over a fine layer of sand. The image was captured by the rover's microscopic imager on the 10th day, or sol, of its mission and roughly approximates the color a human eye would see. Scientists are intrigued by the spherical rocks, which can be formed by a variety of geologic processes, including cooling of molten lava droplets and accretion of concentric layers of material around a particle or "seed". The examined patch of soil is 3 centimeters (1.2 inches) across. The circular grain in the lower left corner is approximately 3 millimeters (.12 inches) across, or about the size of a sunflower seed. This color composite was obtained by merging images acquired with the orange-tinted dust cover in both its open and closed positions. The blue tint at the lower right corner is a tag used by scientists to indicate that the dust cover is closed. *Image Credit*: NASA/JPL/US Geological Survey |

Pathfinder Panorama

Pathfinder Panorama |
| description |
This is a more recent 'geometrically improved, color enhanced' version of the 360-degree 'Gallery Pan', the first contiguous, uniform panorama taken by the Imager for Mars (IMP) over the course of Sols 8, 9, and 10. Different regions were imaged at different times over the three Martian days to acquire consistent lighting and shadow conditions for all areas of the panorama. In this version of the panorama, much of the discontinuity that was due to parallax has been corrected, particularly along thelower tiers of the mosaic containing the Lander features. Distortiondue to a 2.5 degree tilt in the IMP camera mast has been removed. The IMP is a stereo imaging system that, in its fully deployed configuration, stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters. The IMP has color capability provided by 24 selectable filters -- twelve filters per 'eye'. Its red, green, and blue filters were used to take this panorama. The three color images were first digitally balanced according to the transmittance capabilities of a specific high-definition TV device at JPL, and then enhanced via changes to saturation and intensity while retaining the hue. A threshold was applied to avoid changes to the sky. An MTF filter was applied to sharpen feature edges. At left is a Lander petal and a metallic mast which is a portion of the low-gain antenna. On the horizon the double 'Twin Peaks' are visible, about 1-2 kilometers away. The rock 'Couch' is the dark, curved rock at right of Twin Peaks. Another Lander petal is at left-center, showing the fully deployed forward ramp at far left, and rear ramp at right, which rover Sojourner used to descend to the surface of Mars on July 5. Immediately to the left of the rear ramp is the rock 'Barnacle Bill', which scientistsfound be andesitic, possibly indicating that it is a volcanic rock (a true andesite) or a physical mixture of particles. Just beyond Barnacle Bill, rover tracks lead to Sojourner, shown using its Alpha ProtonX-Ray Spectrometer (APXS) instrument to study the large rock 'Yogi'. Yogi, low in quartz content, appears to be more primitive than Barnacle Bill, and appears more like the common basalts found on Earth. The tracks and circular pattern in the soil leading up to Yogi werepart of Sojourner's soil mechanics experiments, in which varying amounts of pressure were applied to the wheels in order to determine physical properties of the soil. During its traverse to Yogi the roverstirred the soil and exposed material from several centimeters indepth. During one of the turns to deploy Sojourner's Alpha Proton X-Ray Spectrometer, the wheels dug particularly deeply and exposed white material. Spectra of this white material show it is virtually identical to the rock 'Scooby Doo', and such white material may underlie much of the site. Deflated airbags are visible at the perimeter of all three Lander petals. Mars Pathfinder was the second in NASA's Discovery, program of low-costspacecraft with highly focused science goals. The Jet PropulsionLaboratory, Pasadena, CA, developed and manages the Mars Pathfindermission for NASA's Office of Space Science, Washington, D.C. JPL is anoperating division of the California Institute of Technology (Caltech).The IMP was developed by the University of Arizona Lunar and PlanetaryLaboratory under contract to JPL. Peter Smith is the Principal Investigator. *Image Credit*: NASA |
