| Description |
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. 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 Imager for Mars Pathfinder (IMP) was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator. ##### |

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.

This image represents the first two tiers of a 360-degree color panoram, taken by the Imager for Mars Pathfinder (IMP). The metallic object at far lower left is a portion of the lander's low-gain antenna. At left, the forward ramp is visible near the larger rocks dubbed Wedge, Flat Top, and Half-Dome. The magenta and yellow strips near the center represent portions of missing data. Rover Sojourner is situated on the soil after its successful deployment on Sol 5. To its immediate left is the rock dubbed "Barnacle Bill," and in front of it lies the larger rock dubbed "Yogi." Two additional areas of deflated airbags are at the right-center and right of the panorama. The mast and windsocks at far right is the Atmospheric Structure Instrument/Meteorology Package (ASI/MET). Their upward position indicates little air movement. A shadow of the ASI/MET has been cast upon a rock just in front of it, indicating sunlight is coming from the rear right.

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.

Victoria Crater' at Meridiani Planum |
| date |
10.06.2006 |
| description |
This image from the High Resolution Imaging Science Experiment on NASA's Mars Reconnaissance Orbiter shows "Victoria crater," an impact crater at Meridiani Planum, near the equator of Mars. The crater is approximately 800 meters (half a mile) in diameter. It has a distinctive scalloped shape to its rim, caused by erosion and downhill movement of crater wall material. Layered sedimentary rocks are exposed along the inner wall of the crater, and boulders that have fallen from the crater wall are visible on the crater floor. The floor of the crater is occupied by a striking field of sand dunes. Since January 2004, the Mars Exploration Rover Opportunity has been operating at Meridiani Planum. Five days before this image was taken, Opportunity arrived at the rim of Victoria crater, after a drive of more than 9 kilometers (over 5 miles). The rover can be seen in this image, at roughly the "ten o'clock" position along the rim of the crater. This view is a portion of an image taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on Oct. 3, 2006. The complete image is centered at minus7.8 degrees latitude, 279.5 degrees East longitude. The range to the target site was 297 kilometers (185.6 miles). At this distance the image scale is 29.7 centimeters (12 inches) per pixel (with 1 x 1 binning) so objects about 89 centimeters (35 inches) across are resolved. The image shown here has been map-projected to 25 centimeters (10 inches) per pixel and north is up. The image was taken at a local Mars time of 3:30 PM and the scene is illuminated from the west with a solar incidence angle of 59.7 degrees, thus the sun was about 30.3 degrees above the horizon. At a solar longitude of 113.6 degrees, the season on Mars is northern summer. This is an enhanced-color view generated from images acquired by the HiRISE camera using its red filter and blue-green filter. Images from the High Resolution Imaging Science Experiment and additional information about the Mars Reconnaissance Orbiter are available online at: http://www.nasa.gov/mroor http://HiRISE.lpl.arizona.edu.

| description |
This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998. This image shows a close-up of the largest crater on Phobos, Stickney, 10 kilometers (6 miles) in diameter. Individual boulders are visible on the near rim of the crater, and are presumed to be ejecta blocks from the impact that formed Stickney. Some of these boulders are enormous - more than 50 meters (160 feet) across. Also crossing at and near the rim of Stickney are shallow, elongated depressions called grooves. This crater is nearly half the size of Phobos and these grooves may be fractures caused by its formation. Phobos was observed by both the Mars Orbiter Camera (MOC) and Thermal Emission Spectrometer (TES). This image is one of the highest resolution images (4 meters or 13 feet per picture element or pixel) ever obtained of the Martian satellite. Malin Space Science Systems, Inc. and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Thermal Emission Spectrometer is operated by Arizona State University and was built by Raytheon Santa Barbara Remote Sensing.

Newly Deployed Sojourner Rover |
| 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.

| Title |
MOC Image of Phobos with TES Temperature Overlay |
| Description |
This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998. The Thermal Emission Spectrometer (TES) measured the brightness of thermal radiation at the same time the camera acquired this image. By analyzing the brightness, TES scientists could deduce the various fractions of the surface exposed to the Sun and their temperatures. This preliminary analysis shows that the surface temperature, dependent on slope and particle size, varies from a high of +25o F (-4o C) on the most illuminated slopes to -170o F (-112o C) in shadows. This large difference, and the fact that such differences can be found in close proximity, adds support to the notion that the surface of Phobos is covered by very small particles. Malin Space Science Systems, Inc. and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Thermal Emission Spectrometer is operated by Arizona State University and was built by Raytheon Santa Barbara Remote Sensing.

High-Resolution MOC Image of Phobos |
| Description |
This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998. This image shows a close-up of the largest crater on Phobos, Stickney, 10 kilometers (6 miles) in diameter. Individual boulders are visible on the near rim of the crater, and are presumed to be ejecta blocks from the impact that formed Stickney. Some of these boulders are enormous - more than 50 meters (160 feet) across. Also crossing at and near the rim of Stickney are shallow, elongated depressions called grooves. This crater is nearly half the size of Phobos and these grooves may be fractures caused by its formation. Phobos was observed by both the Mars Orbiter Camera (MOC) and Thermal Emission Spectrometer (TES). This image is one of the highest resolution images (4 meters or 13 feet per picture element or pixel) ever obtained of the Martian satellite. Malin Space Science Systems, Inc. and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Thermal Emission Spectrometer is operated by Arizona State University and was built by Raytheon Santa Barbara Remote Sensing. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO. |

High-Resolution MOC Image of Phobos with Graphics Overlay |
| Description |
This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998. The white boxes indicate the location of the subframes or close-ups: that on the left is C and that on the right is D. Each box is 1.92 kilometers (1.19 miles) square. The image shows several new features of this lumpy moon -- features that are associated with the prominent crater seen in the upper left quarter of the image. This is the largest crater on Phobos, Stickney, 10 kilometers (6 miles) in diameter. Individual boulders are visible on the near rim of the crater (D), and are presumed to be ejecta blocks from the impact that formed Stickney. Some of these boulders are enormous - more than 50 meters (160 feet) across. Also crossing at and near the rim of Stickney are shallow, elongated depressions called grooves. This crater is nearly half the size of Phobos and these grooves may be fractures caused by its formation. The far wall of the crater shows lighter and darker streaks going down the slopes (C). Phobos was observed by both the Mars Orbiter Camera (MOC) and Thermal Emission Spectrometer (TES). This image is one of the highest resolution images (4 meters or 13 feet per picture element or pixel) ever obtained of the Martian satellite.

High-Resolution MOC Image of Phobos' Face |
| Description |
This image of Phobos, the inner and larger of the two moons of Mars, was taken by the Mars Global Surveyor on August 19, 1998. The minimum distance between the spacecraft and Phobos was 1,080 kilometers (671 miles). Phobos was observed by both the Mars Orbiter Camera (MOC) and Thermal Emission Spectrometer (TES). This image is one of the highest resolution images (4 meters or 13 feet per picture element or pixel) ever obtained of the Martian satellite. The image shows several new features of this lumpy moon -- features that are associated with the prominent crater seen in the upper left quarter of the image. This is the largest crater on Phobos, Stickney, 10 kilometers (6 miles) in diameter. Individual boulders are visible on the near rim of the crater (D), and are presumed to be ejecta blocks from the impact that formed Stickney. Some of these boulders are enormous - more than 50 meters (160 feet) across. Also crossing at and near the rim of Stickney are shallow, elongated depressions called grooves. This crater is nearly half the size of Phobos and these grooves may be fractures caused by its formation. The far wall of the crater shows lighter and darker streaks going down the slopes (C). The presence of material of different brightness on the far crater slopes and in some of the grooves shows that the satellite is heterogeneous (that is, it is made of a mixture of different types of materials). The motion of debris down slopes is guided by gravity, which is only about 1/1000th that of the Earth -- e.g., a 68-kilogram (150- pound) person would weigh only about 57 grams (2 ounces) on Phobos. Previous images from the Viking spacecraft in the 1970's were not of sufficient resolution to show the effectiveness of gravity on Phobos in moving material down slopes. Malin Space Science Systems, Inc. and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Thermal Emission Spectrometer is operated by Arizona State University and was built by Raytheon Santa Barbara Remote Sensing.

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. Lockheed Martin Astronautics, Denver, Colo., is the prime contractor for the project, and developed and built the orbiter.

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.

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 Resoluti

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. This image and PIA02406 (right eye) [ http://photojournal.jpl.nasa.gov/catalog/PIA02406 ] make up a stereo pair.

Improved MPF 360-degree Color Panorama |
| Description |
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 |

Full-Frame Reference for Test Photo of Moon |
| Description |
This pair of views shows how little of the full image frame was taken up by the Moon in test images taken Sept. 8, 2005, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The Mars-bound camera imaged Earth's Moon from a distance of about 10 million kilometers (6 million miles) away -- 26 times the distance between Earth and the Moon -- as part of an activity to test and calibrate the camera. The images are very significant because they show that the Mars Reconnaissance Orbiter spacecraft and this camera can properly operate together to collect very high-resolution images of Mars. The target must move through the camera's telescope view in just the right direction and speed to acquire a proper image. The day's test images also demonstrate that the focus mechanism works properly with the telescope to produce sharp images. Out of the 20,000-pixel-by-6,000-pixel full frame, the Moon's diameter is about 340 pixels, if the full Moon could be seen. The illuminated crescent is about 60 pixels wide, and the resolution is about 10 kilometers (6 miles) per pixel. At Mars, the entire image region will be filled with high-resolution information. The Mars Reconnaissance Orbiter, launched on Aug. 12, 2005, is on course to reach Mars on March 10, 2006. After gradually adjusting the shape of its orbit for half a year, it will begin its primary science phase in November 2006. From the mission's planned science orbit about 300 kilometers (186 miles) above the surface of Mars, the high resolution camera will be able to discern features as small as one meter or yard across. The Mars Reconnaissance Orbiter mission is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, for the NASA Science Mission Directorate. Lockheed Martin Space Systems, Denver, prime contractor for the project, built the spacecraft.

New Mars Camera's First Image of Mars from Mapping Orbit |
| Description |
The high resolution camera on NASA's Mars Reconnaissance Orbiter captured its first image of Mars in the mapping orbit, demonstrating the full resolution capability, on Sept. 29, 2006. The High Resolution Imaging Science Experiment (HiRISE) acquired this image at 8:16 AM (Pacific Time), and parts of the image became available to the HiRISE team at 1:30 PM. With the spacecraft at an altitude of 280 kilometers (174 miles), the image scale is 29.7 centimeters per pixel (about 12 inches per pixel). This sub-image covers a small portion of the floor of Ius Chasma, one branch of the giant Valles Marineris system of canyons. The image illustrates a variety of processes that have shaped the Martian surface. There are bedrock exposures of layered materials, which could be sedimentary rocks deposited in water or from the air. Some of the bedrock has been faulted and folded, perhaps the result of large-scale forces in the crust or from a giant landslide. The darker unit of material at right includes many rocks. The image resolves rocks as small as small as 90 centimeters (3 feet) in diameter. At bottom right are a few dunes or ridges of windblown sand. If a person was located on this part of Mars, he or she would just barely be visible in this image. Image TRA_000823_1720 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on September 29, 2006. Shown here is a small portion of the full image. The full image is centered at minus 7.8 degrees latitude, 279.5 degrees East longitude. The image is oriented such that north is to the top. The range to the target site was 297 kilometers (185.6 miles). At this distance the image scale is 29.7 centimeters per pixel (with one-by-one binning) so objects about 89 centimeters (35 inches) across are resolved. The image was taken at a local Mars time of 3:30 PM and the scene is illuminated from the west with a solar incidence angle of 59.7 degrees, thus the sun was about 30.3 degrees above the horizon. At an LsubS of 113.6 degrees, the season on Mars is Northern Summer / Southern Winter.

2003 Rover |
| Description |
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.

| title |
Landscape West of Bosporos Rupes |
| Description |
This image was taken in the mid-latitudes of Mars' southern hemisphere near the giant Argyre impact basin. It is located just to the west of a prominent scarp known as Bosporos Rupes. The left side of the image shows cratered plains. Some of the craters are heavily mantled and indistinct, whereas others exhibit sharp rims and dramatic topography. The largest crater in this half of the image is about 2.5 kilometers (1.5 miles) wide. Mounds and ridges, which may be remnants of an ice-rich deposit, are visible on its floor. Three sinuous valleys occupy the center of the image. Valleys such as these were first observed in data returned by the NASA Mariner 9 spacecraft, which reached Mars in 1971. The right side of the image shows part of an impact crater that is approximately 20 kilometers (12 miles) in diameter. The furrowed appearance of the crater's inner wall suggests that it has been extensively modified, perhaps by landslides and flowing water. Like other craters in the area, the floor of this crater has a rough and dissected texture that is often attributed to the loss of ice-rich material. Image AEB_000001_0050_Red was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard NASA's Mars Reconnaissance Orbiter spacecraft on March 24, 2006. The image is centered at 40.64 degrees south latitude, 303.49 degrees east longitude. The image is oriented such that north is 7 degrees to the left of up. The range to the target was 2,044 kilometers (1,270 miles). At this distance the image scale is 2.04 meters (6.69 feet) per pixel, so objects as small as 6.1 meters (20 feet) are resolved. In total this image is 40.90 kilometers (25.41 miles) or 20,081 pixels wide and 11.22 kilometers (6.97 miles) or 5,523 pixels high. The image was taken at a local Mars time of 07:30 and the scene is illuminated from the upper right with a solar incidence angle of 81.4 degrees, thus the sun was about 8.6 degrees above the horizon. At an Ls of 29 degrees (with Ls an indicator of Mars' position in its orbit around the sun), the season on Mars is southern autumn.

North Polar Layered Deposits in Summer |
| Description |
The High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter acquired this image during its first day of test imaging from the spacecraft's low-altitude mapping orbit, Sept. 29, 2006. This image of Mars' north polar layered deposits was taken during the summer season (solar longitude of 113.6 degrees), when carbon dioxide frost had evaporated from the surface. The bright spots seen here are most likely patches of water frost, but the location of the frost patches does not appear to controlled by topography. Layers are visible at the bottom of the image, mostly due to difference in slope between them. The variations in slope are probably caused by differences in the physical properties of the layers. Thinner layers that have previously been observed in these deposits are visible, and may represent annual deposition of water ice and dust that is thought to form the polar layered deposits. These deposits are thought to record global climate variations on Mars, similar to ice ages on Earth. HiRISE images such as this should allow Mars' climate record to be inferred and compared with climate changes on Earth. Image TRA_000825_2665 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on September 29, 2006. Shown here is the full image, centered at 86.5 degree latitude, 172.0 degrees east longitude. The image is oriented such that north is to the top. The range to the target site was 298.9 kilometers (186.8 miles). At this distance the image scale is 59.8 centimeters (23.5 inches) per pixel (with two-by-two binning} so objects about 1.79 meters (70 inches) across are resolved. In total the original image was 12.2 kilometers 7.58 mile, 10024 pixels) wide and 6.1 kilometers (3.79 miles, 5000 pixels) long. The image was taken at a local Mars time of 3:30 PM and the scene is illuminated from the southwest with a solar incidence angle of 63.5 degrees, thus the sun was about 26.5 degrees above the horizon.

Lockheed Martin Space Systems is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona. Credit: NASA/JPL/University of Arizona, This image shows a landscape west of Mars' Argyre impact basin and northeast of Halley Crater. The large but faint circular feature near the center of the image is an unnamed impact crater about 7.5 kilometers (4.7 miles) in diameter. It has been all but erased by geological (and probably ice-related) processes. In fact, the majority of impact craters in this image have been modified from their original shapes, some undoubtedly beyond recognition. Only a few small craters remain pristine. The most prevalent surface type in this image is rough, dissected terrain, which is characterized by a complex pattern of knobs, pits, ridges and valleys. In places the rough terrain has been covered by a younger material that appears flat, smooth and nearly featureless. The smooth material may have been emplaced as muddy or icy debris. It filled low-lying areas (most notably craters) and surrounded higher features, preserving islands of rough terrain. Wind-formed dunes have formed atop some of the smooth material, and diagonal streaks on the right side of the image may be due to the winds. Images such as this show the importance of water (liquid and/or ice), wind, and impacts in shaping the surface of Mars. Image AEB_000001_0100_Red was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard NASA's Mars Reconnaissance Orbiter spacecraft on March 24, 2006. The image is centered at 47.14 degrees south latitude, 302.00 degrees east longitude. It is oriented such that north is 7 degrees to the left of up. The range to the target was 1,699 kilometers (1,056 miles). At this distance the image scale is 1.70 meter (5.58 feet) per pixel in the center portion of the image, so objects as small as 5.1 meter (16.7 feet) are resolved. In the side regions the pixels were binned 2x2 to a scale of 3.4 meters (11.2 feet) per pixel. The camera has a total of 10 red-bandpass CCD detectors, and in this image the first 4 CCDs on the left and the last 3 on the right were binned 2x2, while 3 in the middle returned data at full resolution. In total this image is 34.08 kilometers (21.18 miles) or 20,081 pixels wide and 8.50 kilometers (5.28 miles) or 5,164 pixels high. The image was taken at a local Mars time of 07:27 and the scene is illuminated from the upper right with a solar incidence angle of 84.5 degrees, thus the sun was about 5.5 degrees above the horizon. At an Ls of 29 degrees (with Ls an indicator of Mars' position in its orbit around the sun), the season on Mars is southern autumn.

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona. Credit: NASA/JPL/University of Arizona, This image shows part of a low mountain belt that rings the Argyre impact basin in Mars' southern hemisphere. The mountains or hills seen here are located in the northwestern part of the Charitum Montes. Taken just minutes after the sun had risen over the horizon, only the sun-facing slopes are well illuminated and much of the scene is in shadow, but the camera has nevertheless captured many details of the surface that are only dimly illuminated. There are terrains that are both smooth and rough at this scale (2.94 meters or 9.65 feet per pixel). The rough terrain is littered with blocks roughly 10 meters (30 feet) across, and the smooth material has a uniform appearance broken by subtle, undulating ridges. The rough terrains usually occur at relatively high elevations, and smooth material occupies the lowest areas. In some locations it is evident that boulders from the rough terrain have tumbled downhill onto the smooth material. The smooth material is younger than the rough terrain, and some of it may have formed when water-rich or ice-rich debris flooded low-lying areas. In other areas the smooth material mantles the topography like deposits of airborne dust. Further upslope, the mountain flanks have a variety of rough textures. In places the terrain has been eroded into streamlined forms and striations, suggestive of glacial erosion. Gullies formed in one spot near bottom center. Perhaps the most striking aspect of this image is the dearth of fresh impact craters. The Argyre basin is thought to be billions of years old, but much more recent processes have greatly modified the surface. Image AEB_000001_0150_Red was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard NASA's Mars Reconnaissance Orbiter spacecraft on March 24, 2006. The image is centered at 52.20 degrees south latitude, 300.75 degrees east longitude. It is oriented such that north is 7 degrees to the left of up. The range to the target was 1,470 kilometers (913 miles). With 2x2 pixel binning, the scale of the image is 2.94 meters (9.65 feet) per pixel, so objects as small as 8.82 meters (28.94 feet) are resolved. In total this image is 29.47 kilometers (18.31 miles) or 10,040 pixels wide and 76.44 kilometers (47.50 miles) or 26,011 pixels long. The image was taken at a local Mars time of 07:24 and the scene is illuminated from the upper right with a solar incidence angle of 87.1 degrees, thus the sun was about 2.9 degrees above the horizon.

TELEPHONE (818) 354-5011 http://www.jpl.nasa.gov [ http://www.jpl.nasa.gov ] PHOTO CAPTION PIA-00558 [ http://photojournal.jpl.nasa.gov/catalog/PIA00558 ] Earth from Mars Odyssey April 23, 2001 The 2001 Mars Odyssey's thermal emission imaging system acquired these images of the Earth using its visible and infrared cameras as the spacecraft left the Earth. 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. 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 |

Lockheed Martin Space Systems is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona. Credit: NASA/JPL/University of Arizona, This is the first color image of Mars from the High Resolution Imaging Science Experiment on NASA's Mars Reconnaissance Orbiter. At the center portion of the camera's array of light detectors there are extra detectors to image in green and near-infrared color bandpasses, to be combined with the black-and-white images (from red-bandpass detectors) to create color images. This is not natural color as seen by human eyes, but infrared color -- shifted to longer wavelengths. This image also has been processed to enhance subtle color variations. The southern half of the scene is brighter and bluer than the northern half, perhaps due to early-morning fog in the atmosphere. Large-scale streaks in the northern half are due to the action of wind on surface materials. The blankets of material ejected from the many small fresh craters are generally brighter and redder than the surrounding surface, but a few are darker and less red. Two greenish spots in the middle right of the scene may have an unusual composition, and are good future targets for the Compact Reconnaissance Imaging Spectrometer for Mars, a mineral-identifying instrument on Mars Reconnaissance Orbiter (http://crism.jhuapl.edu/ [ http://crism.jhuapl.edu/ ]). In the bottom half of the image we see a redder color in the rough areas, where wind and sublimation of water or carbon dioxide ice have partially eroded patches of smooth-textured deposits. Image AEB_000001_0000_Color was taken by HiRISE on March 24, 2006. The image is centered at 33.65 degrees south latitude, 305.07 degrees east longitude. It is oriented such that north is 7 degrees to the left of up. The range to the target was 2,493 kilometers (1,549 miles). At this distance the image scale is 2.49 meters (8.17 feet) per pixel, so objects as small as 7.5 meters (24.6 feet) are resolved. In total this image is 49.92 kilometers (31.02 miles) or 20,081 pixels wide and 23.66 kilometers (14.70 miles) or 9,523 pixels long. The image was taken at a local Mars time of 07:33 and the scene is illuminated from the upper right with a solar incidence angle of 78 degrees, thus the sun was 12 degrees above the horizon.

Lockheed Martin Space Systems is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona. Credit: NASA/JPL/University of Arizona/USGS, This is a topographic map of part of the area covered by the first image of Mars obtained by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter spacecraft. The image was processed at the U.S. Geological Survey, Flagstaff, by a technique called photoclinometry (or, more descriptively, "shape-from-shading"). This method allows elevations to be reconstructed from a single image by noting how surfaces sloping toward the sun appear brighter than areas that slope away from it. This image is almost ideal for such interpretation because the low sun angle reveals even subtle slopes with dramatic contrast, and variations in the brightness of surface materials (which could be confused with slopes) are minimal. At left is the region of the image that was analyzed, tinted to approximate the visual appearance of the Martian surface. This region is a square 20.4 kilometers (12.7 miles) wide (8,192 pixels by 8,192 pixels at a scale of 2.49 meters or 8.17 feet per pixel). At right is a color-coded topographic contour map of the same area. The total range of elevations is 1.6 kilometers (1 mile), with low areas shown in purple and high areas in red. Contours mark each 20-meter (66-foot) change in elevation. Photoclinometry gives relative rather than absolute heights, but the overall height and shape of features in this map, such as the ridge Ogygis Rupes in the center, agree reasonably well with results from the Mars Orbiter Laser Altimeter on NASA's Mars Odyssey spacecraft, an instrument with high absolute accuracy but relatively low spatial resolution. The real value of mapping by photoclinometry, however, is that it reveals the details of the smallest topographic features resolved by the image. In this example, the image was resampled by a factor of 2 before processing, so the topographic map has a scale of 5 meters (16 feet) per pixel and resolves features as small as 15 meters (49 feet). Computer-generated three-dimensional close-ups of the surface provide one way to visualize these small but important clues to Martian geologic history. This illustration shows a subset of AEB_000001_0000_Red, which was taken by the HiRISE camera on March 24, 2006. The image is oriented such that north is 7 degrees to the left of up. The range to the target was 2,493 kilometers (1,549 miles). At this distance the image scale is 2.49 meters (8.17 feet) per pixel, so objects as small as 7.5 meters (24.6 feet) are resolved. The image was taken at a local Mars time of 07:33 and the scene is illuminated from the upper right with a solar incidence angle of 78.1 degrees, thus the sun was about 11.9 degrees above the horizon. At an Ls of 29 degrees (with Ls an indicator of Mars' position in its orbit around the sun), the season on Mars is southern autumn.

Melas Chasma, Day and Night |
| Description |
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.

The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona. Credit: NASA/JPL/University of Arizona, The first image of Mars by the High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter shows a story of geologic change in the eastern Bosporos Planum region. Old stream valleys cut into the flanks of a gently sloping mountain range in the center of the image. Layers of smooth-textured deposits have mantled the stream valleys and many impact craters. Wind and sublimation of water or carbon dioxide ice have partially eroded patches of the smooth-textured deposits, leaving behind areas of layered and hummocky terrain. A prominent ridge that extends from the top to the bottom of the image dominates the scene. This ridge formed above a thrust fault, a type of fault that occurs when the surface of a planet is compressed. On planetary surfaces, such fault-related ridges are termed "wrinkle ridges." They are commonly observed on Mars, as well as on Earth's moon and on Venus and Mercury. The wrinkle ridge imaged here is named Ogygis Rupes. This wrinkle ridge has deformed several valleys and impact craters. Throughout the scene, geologically young sand dunes are present within stream valleys and some impact craters. The area is also sprinkled with many small young impact craters, which are distinguished by sharp crater rims and bright or dark halos of ejected material. This image demonstrates how a single HiRISE image can capture a multitude of geologic processes. Image AEB_000001_0000_Red was taken by HiRISE on March 24, 2006. The image is centered at 33.65 degrees south latitude, 305.07 degrees east longitude. It is oriented such that north is 7 degrees to the left of up.
