| Description |
This photograph shows the Mars Surveyor '98 Orbiter Color Imager, a high resolution camera that will be flown aboard a NASA orbiter in 1998. The camera will be built by Dr. Michael Malin of Malin Space Science Systems, Inc., San Diego, and the California Institute of Technology in Pasadena, Calif. This tiny instrument consists of two cameras with unique optics and identical focal plane assemblies, data acquisition system electronics and power supplies. The wide-angle camera will acquire daily weather maps of Mars with a surface resolution of 0.8 kilometers up to 7.2 kilometers (0.5 mile to 4.5 miles). The camera produces these maps in five spectral bands, including two ultraviolet bands that will characterize atmospheric ozone and provide global maps of other atmospheric phenomena such as clouds, hazes, dust storms and the polar hood. The medium-angle camera will be used to study selected areas of Mars with a resolution of 40 meters (131 feet) and observe alterations in the planet's surface over time due to changing atmospheric conditions and winds. Ten spectral channels will provide the ability to discriminate both atmospheric and surface features on the basis of composition. The Mars '98 Orbiter mission is tentatively scheduled for launch aboard a Med- Lite expendable launch vehicle in December 1998. The mission will be managed by NASA's Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, D.C. ##### |

The Sojourner rover and undeployed ramps onboard the Mars Pathfinder spacecraft can be seen in in this image, by the Imager for Mars Pathfinder (IMP) on July 4 (Sol 1). This image has been corrected for the curvature created by parallax. The microrover Sojourner is latched to the petal, and has not yet been deployed. The ramps are a pair of deployable metal reels which will provide a track for the rover as it slowly rolls off the lander, over the spacecraft's deflated airbags, and onto the surface of Mars. Pathfinder scientists will use this image to determine whether it is safe to deploy the ramps. One or both of the ramps will be unfurled, and then scientists will decide whether the rover will use either the forward or backward ramp for its descent. Mars Pathfinder is the second in NASA's Discovery program of low- cost spacecraft with highly focused science goals.

This is one of the first pictures taken by the camera on the Mars Pathfinder lander shortly after its touchdown at 10:07 AM Pacific Daylight Time on July 4, 1997. The small rover, named Sojourner, is seen in the foreground in its position on a solar panel of the lander. The white material on either side of the rover is part of the deflated airbag system used to absorb the shock of the landing. Between the rover and the horizon is the rock-strewn martian surface. Two hills are seen in the right distance, profiled against the light brown sky. Pathfinder, a low-cost Discovery mission, is the first of a new fleet of spacecraft that are planned to explore Mars over the next ten years. Mars Global Surveyor, already en route, arrives at Mars on September 11 to begin a two year orbital reconnaissance of the planet's composition, topography, and climate. Additional orbiters and landers will follow every 26 months.

| Description |
The image was taken by the Imager for Mars Pathfinder (IMP) on Sol 4. The rover Sojourner has traveled to an area of soil and several rocks. Its tracks are clearly visible in the soft soil seen in the foreground, and were made in part by the rover's material abrasion experiment. Scientists were able to control the force of the rover's cleated wheels to help determine the physical properties of the soil. In this image, Sojourner is using its Alpha Proton X-Ray Spectrometer (APXS) instrument to study an area of soil. Sunlight is striking the area from the left, creating shadows under Sojourner and at the right of local rocks. The large rock Yogi can be seen at upper right.

| Description |
This pair of images taken by NASA's Galileo spacecraft captures a dynamic eruption at Tvashtar Catena, a chain of volcanic bowls on Jupiter's moon Io. They show a change in the location of hot lava over a period of a few months in 1999 and early 2000. The image on the left uses data obtained on Nov. 26 and July 3, 1999, at resolutions of 183 meters (600 feet) and 1.3 kilometers (0.8 miles) per pixel, respectively. The red and yellow lava flow itself is an illustration based upon imaging data. The image on the right is a composite using a five-color observation made on Feb. 22, 2000, at 315 meters (1030 feet) per pixel. These are among the most fortuitous observations made by Galileo because this style of volcanism is too unpredictable and short-lived to plan to photograph. Short-lived bursts of volcanic activity on Io had been previously detected from Earth-based observations, but interpreting the style of volcanic activity from those lower- resolution views was highly speculative. These Galileo observations confirm hypotheses that the initial, intense thermal output comes from active lava fountains. Galileo's high-resolution observations of volcanic activity on Io have also confirmed other hypotheses based on earlier, low- resolution data. These include interpretations of slowly spreading lava flows at Prometheus and Amirani and an active lava lake at Pele. These tests of earlier hypotheses increase scientists' confidence in interpreting volcanic activity seen in low-resolution remote sensing data of Earth as well as Io. However, these data are still of insufficient resolution to adequately test the more quantitative models that have been applied to volcanic eruptions on Earth and Io. These images also show other geologic features on Io, such as the scalloped margins of the plateau to the northeast of the active lavas. These margins appear to have formed by sapping, a process usually associated with springs of water. Liquid sulfur dioxide might be the fluid responsible for sapping on Io. A better understanding of sapping on Io will influence how scientists interpret similar features on Mars (where the viability of carbon dioxide or water as the sapping fluid remains controversial).

This image compares streaked terrain on Titan and Mars. At left is an image from Cassini of the region where the Huygens probe is expected to land. At right is a picture from NASA's Viking 1 orbiter, showing streaks on Mars caused by winds blowing from right to left. The streaks at the Huygens landing site were formed by some kind of fluid, possibly wind, moving from the upper left to lower right (west to east). The Cassini image was taken on Oct. 26, 2004, by the spacecraft's imaging science subsystem using near-infrared filters. North is 45 degrees to the right of vertical. The scale of this image is 0.83 kilometers (.52 miles) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

Giant Landslide on Iapetus
| Description |
Giant Landslide on Iapetus |
| Full Description |
A spectacular landslide within the low-brightness region of Iapetus's surface known as Cassini Regio is visible in this image from Cassini. Iapetus is one of the moons of Saturn. The landslide material appears to have collapsed from a scarp 15 kilometers high (9 miles) that forms the rim of an ancient 600 kilometer (375 mile) impact basin. Unconsolidated rubble from the landslide extends halfway across a conspicuous, 120-kilometer diameter (75-mile) flat-floored impact crater that lies just inside the basin scarp. Landslides are common geological phenomena on many planetary bodies, including Earth and Mars. The appearance of this landslide on an icy satellite with low-brightness cratered terrain is reminiscent of landslide features that were observed during NASA's Galileo mission on the Jovian satellite Callisto. The fact that the Iapetus landslide traveled many kilometers from the basin scarp could indicate that the surface material is very fine-grained, and perhaps was fluffed by mechanical forces that allowed the landslide debris to flow extended distances. In this view, north is to the left of the picture and solar illumination is from the bottom of the frame. The image was obtained in visible light with the Cassini spacecraft narrow angle camera on Dec. 31, 2004, at a distance of about 123,400 kilometers (76,677 miles) from Iapetus and at a Sun-Iapetus-spacecraft, or phase, angle of 78 degrees. Resolution achieved in the original image was 740 meters (2,428 feet) per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility.

Scrutinizing Titan's Surface
| Description |
Scrutinizing Titan's Surface |
| Full Description |
The six close-up views of Titan's surface shown here are composed of images acquired by the Cassini spacecraft during flybys in October (see Titan Mosaic: October 2004) and December (see Titan Mosaic: December 2004) of 2004. These close-up views illustrate that a variety of processes have shaped the surface of Titan, just as diverse geologic processes are responsible for what we see on Earth's surface. Image (a) shows a prominent bright-dark boundary near the western edge of the Xanadu region which exhibits a sharp, angular edge between the materials. Three bright, discontinuous circles can be seen (two near the top of the image and another near the lower left). These may be large impact craters, the upper two are approximately 30 kilometers (18.6 miles) in diameter and the lower one is approximately 50 kilometers (20 miles) in diameter. Titan's thick atmosphere will screen out small projectiles, but if the surface were as old as Titan itself, it should have many more craters of these sizes. Therefore, Cassini scientists think that, like Earth's surface, Titan's surface has been modified more recently by other geologic processes. However, such processes on Titan may take much longer than on Earth, acting over hundreds of millions of years. Image (b) shows bright features that appear to be streamlined as if were they formed by winds in Titan's atmosphere moving from west to east. The landing site of the Huygens probe is in the upper left corner of this image (see Cassini's View of Titan Landing Site). Image (c) shows a bright feature surrounded by dark material. Several long, dark and narrow lines running through the bright area may be larger examples of the dark channels seen by the Huygens probe (see Mosaic of River Channel and Ridge Area on Titan). These lines are on the order of 2 kilometers (1 mile) wide, and tens of kilometers long. Image (d) shows dark material within the bright area to the west of Xanadu. The linear nature of these features suggests that they may have formed by faulting. They may be dark due to modification by other surface processes occurring on Titan, in the same way that on Earth, fault-lines can be enhanced by erosion and/or deposition of material by water and wind. Image (e) shows brightness variations in the region southeast of the Huygens landing site. The features indicated by arrows exhibit shapes that are similar to drainage patterns seen on Earth and Mars, where the source of the liquid is underground springs rather than rainfall. Image (f) shows a region near the northwestern edge of Xanadu where the boundary between the bright and dark materials is quite complicated. Here some of the bright patches appear as if they represent thin surface plates that have been broken apart and spread apart over underlying dark material. The white bars above each image are 200 kilometers (124 miles) long. Imaging Titan through its thick atmosphere is a challenge, and the narrow, straight lines within the images, are seams between individual images that have not been completely removed. North is to the top of each frame. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

| Full Description |
This map of the surface of Iapetus, generated from images taken by NASA's Cassini and Voyager spacecraft, illustrates the imaging coverage planned for Cassini's very close flyby of the two-toned moon on Sept. 10, 2007. This flyby will be Cassini's only close approach to Iapetus (1,468 kilometers, or 912 miles across) during the entire planned mission. At closest approach, Cassini will be 1,640 kilometers (1,020 miles) above the surface of Iapetus. The spacecraft will pass the moon at a speed of about 2.4 kilometers (1.5 miles) per second--a relatively leisurely pace that will allow plenty of time for the scientific instruments on board to collect massive amounts of data. Cassini's previous encounter with Iapetus, on Dec. 31, 2004, focused on the mysterious territory in Cassini Regio, the region blanketed by dark material that covers most of the moon's leading hemisphere. The upcoming encounter will be primarily concerned with terrain farther west, in the important transition region between Cassini Regio and the bright trailing hemisphere. Scientists hope to learn a great deal more about the composition of the materials that compose the surface of Iapetus during this encounter. Another area of focus is the large equatorial ridge that overlies the moon's equator (see Encountering Iapetus). The ridge reaches 20 kilometers (12 miles) high in some places and extends over 1,300 kilometers (808 miles) in length. No other moon in the solar system has a geological feature like this striking ridge. The tallest mountains on the ridge rival Olympus Mons on Mars, which is approximately three times the height of Mt. Everest. Such giant mountains are a surprising feature for such a small body as Iapetus, which is nearly five times smaller than Mars and nearly nine times smaller than Earth. Colored lines on the map enclose regions that will be covered at different imaging scales as Cassini encounters Iapetus. The highest expected resolution of Cassini images from this flyby is about 20 meters (65 feet) per pixel--significantly higher than the 2004 encounter.

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.

| description |
This 8-image mosaic was acquired during the late afternoon (near 5pm LST, note the long shadows) on Sol 2 as part of the predeploy "insurance panorama" and shows the newly deployed rover sitting on the Martian surface. This color image was generated from images acquired at 530,600, and 750 nm. The insurance panorama was designed as "insurance" against camera failure upon deployment. Had the camera failed, the losslessly-compressed, multispectral insurance panorama would have been the main source of image data from the IMP. However, the camera deployment was successful, leaving the insurance panorama to be downlinked to Earth several weeks later. Ironically enough, the insurance panorama contains some of the best quality image data because of the lossless data compression and relatively dust-free state of the camera and associated lander/rover hardware on Sol 2.

Mars Express Seen by Mars Global Surveyor, This picture shows the Mars Express orbiter as a white, wavy, slanted streak centered against a vast, deep black background. The lines of the spacecraft make it appear somewhat like a jagged, three-inch worm in space. |
| Description |
This picture of the European Space Agency's Mars Express spacecraft by the Mars Orbiter Camera on NASA's Mars Global Surveyor is from the first successful imaging of any spacecraft orbiting Mars by another spacecraft orbiting Mars. The picture is a composite of two views of Mars Express that Mars Orbiter Camera acquired on April 20, 2005, from distances of about 250 and 370 kilometers (155 and 229 miles). Owing to the large distance between Mars Global Surveyor and Mars Express when the two views could be acquired and to a substantial cross-track component of apparent motion for which no correction could be made, Mars Express appears in the image as a narrow blur rather than as a well-defined spacecraft. It appears in the image to be about 1.5 meters in the small dimension and 15 meters in the long dimension, which is consistent with the viewing distance, pixel scale, and encounter geometry. The components of Mars Express when viewed from the same angle as this image can be seen in an artist's rendition http://photojournal.jpl.nasa.gov/figures/PIA07944_fig1.jpg and an annotated rendition http://photojournal.jpl.nasa.gov/figures/PIA07944_fig2.jpg of the spacecraft. Mars Express was launched on June 3, 2003, and reached Mars on Dec. 25, 2003. Mars Global Surveyor left Earth on Nov. 7, 1996, and arrived in Mars orbit on Sept. 12, 1997.

First THEMIS Image of Mars |
| Description |
This thermal infrared image was acquired by Mars Odyssey's thermal emission imaging system on October 30, 2001, as the spacecraft orbited Mars on its ninth revolution around the planet. The image was taken as part of the calibration and testing process of the camera system. This image shows the temperature of Mars in one of the 10 thermal infrared filters. The spacecraft was approximately 22,000 kilometers (about 13,600 miles) above the planet looking down toward the south pole of Mars when this image was acquired. It is late spring in the martian southern hemisphere. The extremely cold, circular feature shown in blue is the martian south polar carbon dioxide ice cap at a temperature of about -120 °C (-184 ° F). The cap is more than 900 kilometers (540 miles) in diameter at this time and will continue to shrink as summer progresses. Clouds of cooler air blowing off the cap can be seen in orange extending across the image to the left of the cap. The cold region in the lower right portion of the image shows the nighttime temperatures of Mars, demonstrating the "night-vision" capability of the camera system to observe Mars even when the surface is in darkness. The warmest regions occur near local noontime. The ring of mountains surrounding the 900-kilometer (540-mile) diameter impact basin Argyre can be seen in the early afternoon in the upper portion of the image. The thin blue crescent along the upper limb of the planet is the martian atmosphere. This image covers a length of over 6,500 kilometers (3,900 miles) spanning the planet from limb to limb, with a resolution of approximately 5.5 kilometers per pixel (3.4 miles per pixel), or picture elements, at the point directly beneath the spacecraft. The Odyssey's infrared camera is planned to have a resolution of 100 meters per pixel (about 300 feet per pixel) from its mapping orbit. JPL manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The thermal emission imaging system was developed at Arizona State University, Tempe with Raytheon Santa Barbara Remote Sensing, Santa Barbara, Calif.

Rolling Stones Make New Boul
…

Rolling Stones Make New Boulder Tracks |
| Description |
When a boulder rolls down a dusty slope, it can leave behind a trail of depressions. Usually known as boulder tracks, these features have been documented and studied on Earth, the Moon, and Mars. Geologists studying the Moon and Mars can use these tracks to learn about the physical properties of the fine-grained debris encountered by the boulder as it rolled down the slope. Because of the high-resolution capability (0.5 to 12 meters, 1.6 to 39 feet, per pixel) of the Mars Orbiter Camera on NASA's Mars Global Surveyor spacecraft, dozens of boulder track sites have been identified on the red planet. A Mars Orbiter Camera image of one set of boulder tracks in a south mid-latitude crater (located near 35.8 degrees south latitude, 158.4 degrees west longitude) was obtained on Nov. 14, 2003, (left). A second image of the same site, from Dec. 4, 2004, (right) shows that more than a dozen new boulder tracks formed on the crater wall during the intervening time. Mars is an active planet, with geologic changes occurring -- at some scale -- every day. In this case, some time between mid November 2003 and early December 2004, a suite of boulders became dislodged from the crater wall, then rolled and perhaps bounced their way to the crater floor. Wider context for the site can be seen in a mosaic of Mars Orbiter Camera wide-angle images acquired in May 1999 (insert MOC2-1213a). The white box indicates the location of the later, higher-resolution views. Why the new boulders slid down the slope is unknown. This is the product of a mass movement (landsliding) process. That is, gravity is the main culprit. Whether the boulder motion was triggered by something -- a seismic event ("Marsquake") or strong winds -- is not known. Also unknown is whether all of the new boulder tracks formed at the same time, in response to a single event, or rolled downhill one at a time over the nearly 13-month period. The Mars Orbiter Camera was built and is operated by Malin Space Science Systems, San Diego, Calif. Mars Global Surveyor left Earth on Nov. 7, 1996, and began orbiting Mars on Sept. 12, 1997.

Poohbear Rock |
| Description |
This image, taken by Sojourner's front right camera, was taken when the rover was next to Poohbear (rock at left) and Piglet (not seen) as it looked out toward Mermaid Dune. The textures differ from the foreground soil containing a sorted mix of small rocks, fines and clods, from the area a bit ahead of the rover where the surface is covered with a bright drift material. Soil experiments where the rover wheels dug in the soil revealed that the cloudy material exists underneath the drift.

First THEMIS Infrared and Visible Images of Mars |
| Description |
This picture shows both a visible and a thermal infrared image taken by the thermal emission imaging system on NASA's 2001 Mars Odyssey spacecraft on November 2, 2001. The images were taken as part of the ongoing calibration and testing of the camera system as the spacecraft orbited Mars on its 13th revolution of the planet. The visible wavelength image, shown on the right in black and white, was obtained using one of the instrument's five visible filters. The spacecraft was approximately 22,000 kilometers (about 13,600 miles) above Mars looking down toward the south pole when this image was acquired. It is late spring in the martian southern hemisphere. The thermal infrared image, center, shows the temperature of the surface in color. The circular feature seen in blue is the extremely cold martian south polar carbon dioxide ice cap. The instrument has measured a temperature of minus 120 degrees Celsius (minus184 degrees Fahrenheit) on the south polar ice cap. The polar cap is more than 900 kilometers (540 miles) in diameter at this time. The visible image shows additional details along the edge of the ice cap, as well as atmospheric hazes near the cap. The view of the surface appears hazy due to dust that still remains in the martian atmosphere from the massive martian dust storms that have occurred over the past several months. The infrared image covers a length of over 6,500 kilometers (3,900 miles) spanning the planet from limb to limb, with a resolution of approximately 5.5 kilometers per picture element, or pixel, (3.4 miles per pixel) at the point directly beneath the spacecraft. The visible image has a resolution of approximately 1 kilometer per pixel (.6 miles per pixel) and covers an area roughly the size of the states of Arizona and New Mexico combined. NASA's Jet Propulsion Laboratory, Pasadena, Calif. manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington D.C. The thermal-emission imaging system was developed at Arizona State University, Tempe, with Raytheon Santa Barbara Remote Sensing, Santa Barbara, Calif.

Close-up of Moe - Left Eye |
| Description |
A close-up view of the rock 'Moe' in the Rock Garden at the Pathfinder landing site. Moe is a meter-size boulder that, as seen from Sojourner, has a relatively smooth yet pitted texture upon close examination. Such a texture is seen on Earth on rocks that have been abraded by wind in a process that is analogous to sand blasting. This view of Moe shows two faces on the rock, one (left side of the rock) facing north-northeast and the other (right side) facing east. These two faces are thought to have been pitted and fluted by strong, 'sand'- carrying winds from the northeast. This image and PIA01565 [ http://photojournal.jpl.nasa.gov/catalog/PIA01565 ] (right eye) make up a stereo pair.

Acheron Fossae in Visible Light |
| Description |
This visible-light image, taken by the thermal emission imaging system's camera on NASA's 2001 Mars Odyssey spacecraft, shows the highly fractured, faulted and deformed Acheron Fossae region of Mars. The scarps visible in this image are approximately one kilometer (3,300 feet) high, based on topography derived from the laser altimeter instrument on Mars Global Surveyor. Dark streaks only 50 meters (164 feet) across can be seen on some of the cliff faces. These streaks may be formed when the pervasive dust mantle covering this region gives way on steep slopes to create dust avalanches. The image also shows impact craters as small as 500 meters (1,640 feet) in diameter, as well as smooth and textured plains. Acheron Fossae is located 1,050 kilometers (650 miles) north of the large shield volcano Olympus Mons. This image covers an area about 18 by 9 kilometers (11 by 6 miles) centered at 37 degrees north, 131 degrees west. North is to the top of this image, which was acquired on February 19, 2002, at about 3:15 p.m. local Martian time.

Twin Peaks in Super Resolution - Left Eye |
| Description |
The Twin Peaks are modest-size hills to the southwest of the Mars Pathfinder landing site. They were discovered on the first panoramas taken by the IMP camera on the 4th of July, 1997, and subsequently identified in Viking Orbiter images taken over 20 years ago. The peaks are approximately 30-35 meters (-100 feet) tall. North Twin is approximately 860 meters (2800 feet) from the lander, and South Twin is about a kilometer away (3300 feet). The scene includes bouldery ridges and swales or 'hummocks' of flood debris that range from a few tens of meters away from the lander to the distance of the South Twin Peak. The composite color frames that make up this 'left-eye' image consist of 8 frames, taken with different color filters that were enlarged by 500% and then co- added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. This panchromatic frame was then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars.

Improved MPF 360-degree Color Panorama |

Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is an operating division of the California Institute of Technology (Caltech). The IMP was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator., 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 the lower tiers of the mosaic containing the Lander features. Distortion due 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 scientists found 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 Proton X-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 were part 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 rover stirred the soil and exposed material from several centimeters in depth. 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 is the second in NASA's |

This artist's rendering shows a view of NASA's Mars 2003 Rover as it sets off roam the surface of the red planet. The rover is scheduled for launch in June 2003 and will arrive in January 2004, shielded in its landing by an airbag shell. The airbag/lander structure, which has no scientific instruments of its own, is shown to the right in this image, behind the rover. The rover will carry five scientific instruments and rock abrading device. The Panoramic Camera and the Miniature Thermal Emission Spectrometer are located on the large mast shown on the front of the rover. The camera will be supplied by NASA's Jet Propulsion Laboratory, Pasadena, Calif., and the spectrometer will be supplied by Arizona State University in Tempe. The payload also includes magnetic targets, provided by the Niels Bohr Institute in Copenhagen, Denmark, that will collect magnetic dust for further study by the science instruments. The Rock Abrasion Tool is located on a robotic arm that can be deployed to study rocks and soil.(In this view, the robotic arm is tucked under the front of the rover.) The tool, provided by Honeybee Robotics Ltd., New York, N.Y., will grind away the outer surfaces of rocks, which may be dusty and weathered, allowing the science instruments to determine the nature of rock interiors. The three instruments that will study the abraded rocks are a Mossbauer Spectrometer, provided by the Johannes Gutenberg- University Mainz, Germany, an Alpha-Proton X-ray Spectrometer provided by Max Planck Institute for Chemistry, also in Mainz, Germany, and a Microscopic Imager, supplied by JPL. The payload also includes magnetic targets, provided by the Niels Bohr Institute in Copenhagen, Denmark, that will collect magnetic dust for further study by the science instruments. In a landing similar to that of the 1997 Mars Pathfinder spacecraft, a parachute will deploy to slow the spacecraft down and airbags will inflate to cushion the landing. Petals of the landing structure will unfold to release the rover, which will drive off to begin its exploration. JPL manages the Mars 2003 Rover for NASA's Office of Space Science, Washington, D.C.

The visible light image shows the thin crescent viewed from Odyssey's perspective. The infrared image was acquired at exactly the same time, but shows the entire Earth using the infrared's "night-vision" capability. In visible light, the instrument sees only reflected sunlight and therefore sees nothing on the night side of the planet. In infrared light the camera observes the light emitted by all regions of the Earth. The coldest ground temperatures seen correspond to the nighttime regions of Antarctica, the warmest temperatures occur in Australia. The low temperature in Antarctica is minus 50 degrees Celsius (minus 58 degrees Fahrenheit), the high temperature at night in Australia 9 degrees Celsius (48.2 degrees Fahrenheit). These temperatures agree remarkably well with observed temperatures of minus 63 degrees Celsius at Vostok Station in Antarctica, and 10 degrees Celsius in Australia. The images were taken at a distance of 3,563,735 kilometers (more than 2 million miles) on April 19, 2001 as the Odyssey spacecraft left Earth. Mars Odyssey carries three scientific instruments designed to tell us what the Martian surface is made of and about its radiation environment: a thermal-emission imaging system, a gamma ray spectrometer and a Martian radiation environment experiment. Odyssey will arrive at Mars on October 24, when it will fire its main engine and be captured into Mars' orbit. The Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. Principal investigators at Arizona State University in Tempe, the University of Arizona in Tuscon, and NASA's Johnson Space Center, Houston, Texas, will operate the science instruments. Lockheed Martin Astronautics, Denver, Colo., is the prime contractor for the project, and developed and built the orbiter. Mission operations will be conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.

This image is a mosaic of day and night infrared images of Melas Chasma taken by the camera system on NASA's Mars Odyssey spacecraft. The daytime temperature images are shown in black and white, superimposed on the martian topography. A single nighttime temperature image is superimposed in color. The daytime temperatures range from approximately -35 degrees Celsius (-31 degrees Fahrenheit) in black to -5 degrees Celsius (23 degrees Fahrenheit) in white. Overlapping landslides and individual layers in the walls of Melas Chasma can be seen in this image. The landslides flowed over 100 kilometers (62 miles) across the floor of Melas Chasma, producing deposits with ridges and grooves of alternating warm and cold materials that can still be seen. The temperature differences in the daytime images are due primarily to lighting effects, where sunlit slopes are warm (bright) and shadowed slopes are cool (dark). The nighttime temperature differences are due to differences in the abundance of rocky materials that retain their heat at night and stay relatively warm (red). Fine grained dust and sand (blue) cools off more rapidly at night. These images were acquired using the thermal infrared imaging system infrared Band 9, centered at 12.6 micrometers. Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the 2001 Mars Odyssey mission for NASA's Office of Space Science in Washington, D.C. Investigators at Arizona State University in Tempe, the University of Arizona in Tucson and NASA's Johnson Space Center, Houston, operate the science instruments. Additional science partners are located at the Russian Aviation and Space Agency and at Los Alamos National Laboratories, New Mexico. Lockheed Martin Astronautics, Denver, is the prime contractor for the project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL.

First THEMIS Infrared and Visible Images of Mars |
| Description |
This picture shows both a visible and a thermal infrared image taken by the thermal emission imaging system on NASA's 2001 Mars Odyssey spacecraft on November 2, 2001. The images were taken as part of the ongoing calibration and testing of the camera system as the spacecraft orbited Mars on its 13th revolution of the planet. The visible wavelength image, shown on the right in black and white, was obtained using one of the instrument's five visible filters. The spacecraft was approximately 22,000 kilometers (about 13,600 miles) above Mars looking down toward the south pole when this image was acquired. It is late spring in the martian southern hemisphere. The thermal infrared image, center, shows the temperature of the surface in color. The circular feature seen in blue is the extremely cold martian south polar carbon dioxide ice cap. The instrument has measured a temperature of minus 120 degrees Celsius (minus184 degrees Fahrenheit) on the south polar ice cap. The polar cap is more than 900 kilometers (540 miles) in diameter at this time. The visible image shows additional details along the edge of the ice cap, as well as atmospheric hazes near the cap. The view of the surface appears hazy due to dust that still remains in the martian atmosphere from the massive martian dust storms that have occurred over the past several months. The infrared image covers a length of over 6,500 kilometers (3,900 miles) spanning the planet from limb to limb, with a resolution of approximately 5.5 kilometers per picture element, or pixel, (3.4 miles per pixel) at the point directly beneath the spacecraft. The visible image has a resolution of approximately 1 kilometer per pixel (.6 miles per pixel) and covers an area roughly the size of the states of Arizona and New Mexico combined. NASA's Jet Propulsion Laboratory, Pasadena, Calif. manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington D.C. The thermal-emission imaging system was developed at Arizona State University, Tempe, with Raytheon Santa Barbara Remote Sensing, Santa Barbara, Calif. Lockheed Martin Astronautics, Denver, is the prime contractor for the project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.

It was taken at distance of 3,563,735 kilometers (more than 2 million miles) on April 19, 2001 as the 2001 Mars Odyssey spacecraft left the Earth. From this distance and perspective the camera was able to acquire an image that directly shows the true distance from the Earth to the Moon. The Earth's diameter is about 12,750 kilometers, and the distance from the Earth to the Moon is about 385,000 kilometers, corresponding to 30 Earth diameters. The dark region seen on Earth in the infrared temperature image is the cold south pole, with a temperature of minus 50 degrees Celsius (minus 58 degrees Fahrenheit). The small bright region above it is warm Australia. This image was acquired using the 9.1 micron infrared filter, one of nine filters that the instrument will use to map the mineral composition and temperature of the Martian surface. From this great distance, each picture element (pixel) in the image corresponds to a region 900 by 900 kilometers (about 560 by 560 miles). Once Odyssey reaches Mars orbit each infrared pixel will cover a region only 100 by 100 meters on the surface (about 330 by 330 feet), about the size of a major league baseball field. Mars Odyssey carries three scientific instruments designed to tell us what the Martian surface is made of and about its radiation environment: a thermal-emission imaging system, a gamma ray spectrometer and a Martian radiation environment experiment. Odyssey will arrive at Mars on October 24, when it will fire its main engine and be captured into Mars' orbit. The Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. Principal investigators at Arizona State University in Tempe, the University of Arizona in Tuscon, and NASA's Johnson Space Center, Houston, Texas, will operate the science instruments. Lockheed Martin Astronautics, Denver, Colo., is the prime contractor for the project, and developed and built the orbiter. Mission operations will be conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena. The thermal emission imaging system was built by Raytheon Santa Barbara Remote Sensing, Santa Barbara, Calif. and is operated by Arizona State University. ##### Image credit: NASA/Jet Propulsion Laboratory/Arizona State University |

Candor Chasma on Mars, in Color |
| Description |
This image from the camera system on NASA's Mars Odyssey was acquired of Candor Chasma within Valles Marineris, centered near 5 degrees south latitude, 283 degrees west longitude. This visible color image shows the effects of erosion on a sequence of dramatically layered rocks. These layers were initially deposited within Candor Chasma and have subsequently been eroded by a variety of processes, including wind and down-slope motion due to gravity. Relatively dark materials appear to mantle some areas of the layered deposits, these dark materials are likely sand. Few impact craters of any size can be seen in this image, indicating that the erosion and transport of material is occurring at a relatively rapid rate, so that any craters that form are rapidly buried or eroded. This image was acquired using the thermal infrared imaging system's visible bands 1 (centered at 420 nanometers), 2 (centered at 550 nanometers), and 3 (centered at 650 nanometers), and covers an area approximately 19 kilometers (12 miles) in width by 50 kilometers (50 miles) in length.

Gusev Crater |
| Description |
This mosaic of nighttime infrared images of Gusev Crater, taken by the camera system on the Mars Odyssey spacecraft, has been draped over topography data obtained by Mars Global Surveyor. Variations in nighttime temperatures are due to differences in the abundance of rocky materials that retain their heat at night and stay relatively warm (bright). Fine grained dust and sand (dark) cools off more rapidly at night. This image mosaic covers an area approximately 180 kilometers (110 miles) on each side centered near 14 degrees S, 175 degrees E, looking toward the south in this simulated view.

Global map of epithermal neutrons |
| Description |
Observations by NASA's 2001 Mars Odyssey spacecraft show a global view of Mars in intermediate-energy, or epithermal, neutrons. Soil enriched by hydrogen is indicated by the deep blue colors on the map, which show a low intensity of epithermal neutrons. Progressively smaller amounts of hydrogen are shown in the colors light blue, green, yellow and red. The deep blue areas in the polar regions are believed to contain up to 50 percent water ice in the upper one meter (three feet) of the soil. Hydrogen in the far north is hidden at this time beneath a layer of carbon dioxide frost (dry ice). Light blue regions near the equator contain slightly enhanced near-surface hydrogen, which is most likely chemically or physically bound because water ice is not stable near the equator. The view shown here is a map of measurements made during the first three months of mapping using the neutron spectrometer instrument, part of the gamma ray spectrometer instrument suite. The central meridian in this projection is zero degrees longitude. Topographic features are superimposed on the map for geographic reference. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. Investigators at Arizona State University in Tempe, the University of Arizona in Tucson, and NASA's Johnson Space Center, Houston, operate the science instruments. The gamma-ray spectrometer was provided by the University of Arizona in collaboration with the Russian Aviation and Space Agency, which provided the high-energy neutron detector, and the Los Alamos National Laboratories, New Mexico, which provided the neutron spectrometer. Lockheed Martin Astronautics, Denver, is the prime contractor for the project, and developed and built the orbiter.
