| Description |
The upper-left of these images shows the passing, or transit, of the Martian moon Deimos across the sun. This event is similar to solar eclipses seen from Earth in which our moon crosses in front of the sun. The bottom three images show Phobos, Mars's other moon, transiting the sun. The potato-shaped Phobos is roughly 15 miles across, about twice the size of Deimos. Deimos appears so much smaller because it is also a bit more than twice as far away from Mars as Phobos is. The Mars Exploration Rover Opportunity took images of both moons on different days in March 2004. Image credit: NASA/JPL/Cornell |

Cape Verde, Mars
This Mars Exploration Rover
4/1/08
| Description |
This Mars Exploration Rover Opportunity Pancam "super resolution" mosaic of the approximately 6 meter (20 foot) high cliff face of the Cape Verde promontory was taken by the rover from inside Victoria Crater, during the rover's descent into Duck Bay. Super-resolution is an imaging technique that utilizes information from multiple pictures of the same target in order to generate an image with a higher resolution than any of the individual images. Cape Verde is a geologically rich outcrop and is teaching scientists about how rocks at Victoria crater were modified since they were deposited long ago. This image complements super resolution mosaics obtained at Cape St. Mary and Cape St. Vincent and is consistent with the hypothesis that Victoria crater is located in the middle of what used to be an ancient sand dune field. This image was acquired on sols 1342 and 1356 (Nov. 2 and 17, 2007). Image Credit: NASA/JPL-Caltech/Cornell University |

NASA's Mars Exploration Rove
4/16/09
| Description |
NASA's Mars Exploration Rover Spirit used its navigation camera to take the images that have been combined into this 180-degree view of the rover's surroundings during the 1,823rd Martian day, or sol, of Spirit's surface mission (Feb. 17, 2009). The center of the view is toward the south-southwest. The rover had driven 23 feet, or 7 meters, eastward earlier on Sol 1823, part of maneuvering to get Spirit into a favorable position for climbing onto the low plateau called 'Home Plate.' However, after two driving attempts with negligible progress during the following three sols, the rover team changed its strategy for getting to destinations south of Home Plate. The team decided to drive Spirit at least partway around Home Plate, instead of ascending the northern edge and taking a shorter route across the top of the plateau. Image Credit: NASA/JPL-Caltech |

Spirit's Robotic Stretch
NASA's Mars Exploration Rove
10/22/09
| Description |
NASA's Mars Exploration Rover Spirit recorded this forward view of its arm and surroundings during the rover's 2,052nd Martian day, or sol, on Oct. 11, 2009. Bright soil in the left half of the image is loose, fluffy material churned by the rover's left-front wheel as Spirit, driving backwards, approached its current position in April 2009 and the wheel broke through a darker, crusty surface. Spirit used its front hazard-avoidance camera to take this image. The turret of tools at the end of the rover's robotic arm is positioned with the Moessbauer spectrometer up and the rock abrasion tool extending toward the right. Spirit's right-front wheel, visible in this image, has not worked since 2006. It is the least-embedded of the rover's six wheels at the current location, called "Troy." Spirit and its twin, Opportunity, have been working on Mars for more than 58 months in what were originally planned as 3-month missions on Mars. Image Credit: NASA/JPL-Caltech |

Spirit Stuck in Soft Soil on
This view from the panoramic
11/2/09
| Description |
This view from the panoramic camera on NASA's Mars Exploration Rover Spirit shows the terrain surrounding the location called "Troy," where Spirit became embedded in soft soil during the spring of 2009. The hundreds of images combined into this view were taken beginning on the 1,906th Martian day (or sol) of Spirit's mission on Mars (May 14, 2009) and ending on Sol 1943 (June 20, 2009). Near the center of the image, in the distance, lies Husband Hill, where Spirit recorded views from the summit in 2005. For scale, the parallel tracks are about 1 meter (39 inches) apart. The track on the right is more evident because Spirit was driving backwards, dragging its right-front wheel, which no longer rotates. The bright soil in the center foreground is soft material in which Spirit became embedded after the wheels on that side cut through a darker top layer. The composition of different layers in the soil at the site became the subject of intense investigation by tools on Spirit's robotic arm. In recent weeks, Engineers have been using test rovers on Earth to prepare for extracting the sand-trapped Spirit rover. While amnesia-like symptoms in recent days might delay the start of planned drives by Spirit geared towards extricating it, the Mars Exploration Rover team remains hopeful. "If they are intermittent and infrequent, they are a nuisance that would set us back a day or two when they occur. If the condition becomes persistent or frequent, we will need to go to an alternate strategy that avoids depending on flash memory, " said Project Manager John Callas of NASA's Jet Propulsion Laboratory. In these amnesia events, Spirit fails to record data from the day's activities onto the type of computer memory -- non-volatile "flash" memory -- that can retain the data when the rover powers down for its energy-conserving periods of "sleep." Spirit has worked on Mars for more than 69 months in what was originally planned as a three-month mission. |

11/12/09
| Description |
This view from the navigation camera on NASA's Mars Exploration Rover Opportunity shows tracks left by backing out of a wind-formed ripple after the rover's wheels had started to dig too deeply into the dust and sand of the ripple. The frames combined into this view were taken on the 1,867th Martian day, or sol, of Opportunity's mission on Mars (April 25, 2009). The scene spans 120 degrees, from southeastward on the left to westward on the right. Two sols earlier, Opportunity drove 310 feet south-southwestward before stopping when the rover detected that its wheels were slipping more than the limit that engineers had set for the drive. That Sol 1865 (April 23, 2009) drive created the tracks that enter this scene from the left and ended with wheels on the left side of the rover partially embedded in the ripple. On Sol 1866, Opportunity began to back away from this potential trap, but moved only about 11 inches. On Sol 1867, the rover backed up 12 feet before taking this picture. Subsequently, Opportunity proceeded on a path avoiding the ripple where the wheel slippage occurred. For scale, the distance between the parallel wheel tracks is about about 40 inches). This view is presented as a cylindrical projection with geometric seam correction. Image Credit: NASA/JPL-Caltech |

| Description |
This image of a cluster of rocks labeled 'Rock Garden' is where NASA's Mars Exploration Rover Spirit became embedded in April 2009. The Spirit and Opportunity rovers landed on the Red Planet in January 2004 for what was to be a 90-day mission, but which has lasted 6 Earth years, or 3.2 Mars years. During this time, Spirit has found evidence of a steamy and violent environment on ancient Mars that is quite different from the wet and acidic past documented by Opportunity, which has been operating successfully as it explores halfway around the planet. Spirit used its navigation camera to capture this view of the terrain toward the southeast from the location it reached on the 1,870th Martian day, or sol, on April 7, 2009. Wheels on the western side of the rover broke through the dark, crusty surface into bright, loose, sandy material that was not visible as the rover approached the site. Spirit became stuck in an area near the left of the image's center later in April. Image Credit: NASA/JPL-Caltech |

This image mosaic taken by the panoramic camera onboard the Mars Exploration Rover Spirit shows the rover's landing site, the Columbia Memorial Station, at Gusev Crater, Mars. This spectacular view may encapsulate Spirit's entire journey, from lander to its possible final destination toward the east hills. On its way, the rover will travel 250 meters (820 feet) northeast to a large crater approximately 200 meters (660 feet) across, the ridge of which can be seen to the left of this image. To the right are the east hills, about 3 kilometers (2 miles) away from the lander. The picture was taken on the 16th martian day, or sol, of the mission (Jan. 18/19, 2004). A portion of Spirit's solar panels appear in the foreground. Data from the panoramic camera's green, blue and infrared filters were combined to create this approximate true color image. *Image Credit*: NASA/JPL/Cornell |

The interior of a crater surrounding the Mars Exploration Rover Opportunity at Meridiani Planum on Mars can be seen in this color image from the rover's panoramic camera. This is the darkest landing site ever visited by a spacecraft on Mars. The rim of the crater is approximately 10 meters (32 feet) from the rover. The crater is estimated to be 20 meters (65 feet) in diameter. Scientists are intrigued by the abundance of rock outcrops dispersed throughout the crater, as well as the crater's soil, which appears to be a mixture of coarse gray grains and fine reddish grains. Data taken from the camera's near-infrared, green and blue filters were combined to create this approximate true color picture, taken on the first day of Opportunity's journey. The view is to the west-southwest of the rover. *Image Credit*: NASA/JPL/Cornell |

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

These two images from 10 days apart show that dust was removed from the panoramic camera's calibration target on NASA's Mars Exploration Rover Spirit. Spirit's panoramic camera took the picture on the left on the rover's 416th martian day, or sol, (March 5, 2005) and took the picture on the right on sol 426 (March 15, 2005). During the time in-between, other evidence of dust-lifting winds were a jump in power output by Spirit's solar arrays on sol 420 from removal of some accumulated dust, and sighting of two dust devils in sol 421 images from Spirit. The size of the base plate on the calibration target shown in both of these images is 8 centimeters (3.15 inches) on each side. These are the panoramic camera team's best current attempt at generating "true color" views of what these scenes would look like if viewed by a human on Mars. They were generated from mathematical combinations of six calibrated, left-eye Pancam images for each sequence, using filters ranging from 430-nanometer to 750-nanometer wavelengths.

Martian Meteorite
| title |
Martian Meteorite |
| description |
NASA's Mars Exploration Rover Opportunity has found an iron meteorite, the first meteorite of any type ever identified on another planet. The pitted, basketball-size object is mostly made of iron and nickel according to readings from spectrometers on the rover. Only a small fraction of the meteorites fallen on Earth are similarly metal-rich. Others are rockier. As an example, the meteorite that blasted the famous Meteor Crater in Arizona is similar in composition. "This is a huge surprise, though maybe it shouldn't have been," said Dr. Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for the science instruments on Opportunity and its twin, Spirit. The meteorite, dubbed "Heat Shield Rock," sits near debris of Opportunity's heat shield on the surface of Meridiani Planum, a cratered flatland that has been Opportunity's home since the robot landed on Mars nearly one year ago. "I never thought we would get to use our instruments on a rock from someplace other than Mars," Squyres said. "Think about where an iron meteorite comes from: a destroyed planet or planetesimal that was big enough to differentiate into a metallic core and a rocky mantle." Rover-team scientists are wondering whether some rocks that Opportunity has seen atop the ground surface are rocky meteorites. "Mars should be hit by a lot more rocky meteorites than iron meteorites," Squyres said. "We've been seeing lots of cobbles out on the plains, and this raises the possibility that some of them may in fact be meteorites. We may be investigating some of those in coming weeks. The key is not what we'll learn about meteorites -- we have lots of meteorites on Earth -- but what the meteorites can tell us about Meridiani Planum." The numbers of exposed meteorites could be an indication of whether the plain is gradually eroding away or being built up. NASA Chief Scientist Dr. Jim Garvin said, "Exploring meteorites is a vital part of NASA's scientific agenda, and discovering whether there are storehouses of them on Mars opens new research possibilities, including further incentives for robotic and then human-based sample-return missions. Mars continues to provide unexpected science 'gold,' and our rovers have proven the value of mobile exploration with this latest finding." Initial observation of Heat Shield Rock from a distance with Opportunity's miniature thermal emission spectrometer suggested a metallic composition and raised speculation last week that it was a meteorite. The rover drove close enough to use its Moessbauer and alpha particle X-ray spectrometers, confirming the meteorite identification over the weekend. Opportunity and Spirit successfully completed their primary three-month missions on Mars in April 2004. NASA has extended their missions twice because the rovers have remained in good condition to continue exploring Mars longer than anticipated. They have found geological evidence of past wet environmental conditions that might have, been hospitable to life. Opportunity has driven a total of 2.10 kilometers (1.30 miles). Minor mottling from dust has appeared in images from the rover's rear hazard-identification camera since Opportunity entered the area of its heat-shield debris, said Jim Erickson of NASA's Jet Propulsion Laboratory, Pasadena, Calif., rover project manager. The rover team plans to begin driving Opportunity south toward a circular feature called "Vostok" within about a week. Spirit has driven a total of 4.05 kilometers (2.52 miles). It has been making slow progress uphill toward a ridge on "Husband Hill" inside Gusev Crater. *Image Credit*: NASA |

Taking advantage of extra solar energy collected during the day, NASA's Mars Exploration Rover Spirit settled in for an evening of stargazing, photographing the two moons of Mars as they crossed the night sky. "It is incredibly cool to be running an observatory on another planet," said planetary scientist Jim Bell of Cornell University, Ithaca, N.Y., lead scientist for the panoramic cameras on Spirit and Opportunity. In this animation, both martian moons, Deimos on the left and Phobos on the right, travel across the night sky in front of the constellation Sagittarius. Part of Sagittarius resembles an upside-down teapot. Phobos is the brighter object on the right, Deimos is on the left. Spirit acquired these enhanced-brightness images with the panoramic camera on the night of sol 585 (Aug. 26, 2005). Scientists will use images of the two moons to better map their orbital positions, learn more about their composition, and monitor the presence of nighttime clouds or haze. Spirit took the six images that make up this animation using the camera's broadband filter, which was designed specifically for acquiring images under low-light conditions. *Image credit:* NASA/JPL/Cornell/ Texas A&M |

Mars Rover Panorama Shows Vista From 'Lookout' Point |
| date |
04.29.2005 |
| description |
From a ridgeline vantage point overlooking slopes, valleys and plains, NASA's Mars Exploration Rover Spirit has returned its latest color panorama of the martian landscape. The approximately true color image shows a full 360-degree view from a site informally named "Larry's Lookout," about halfway up "Husband Hill." Dr. Jim Bell of Cornell University, Ithaca, N.Y., lead scientist for the panoramic cameras on both the Spirit and Opportunity Mars rovers, said, "Spirit and the rover team worked hard over many weeks to get to this vantage point along the flanks of Husband Hill. The rugged ridge and valley terrain seen here is similar in some respects to the view seen months earlier at the 'West Spur,' but the chemistry and mineralogy here are significantly different. Specifically, some of the areas seen here amid the outcrop rocks and in places where the subsurface was exposed by the rover wheels contain the highest sulfur abundances ever measured by Spirit." The view includes the summit of Husband Hill about 200 meters (about 660 feet) southward and about 45 meters (about 150 feet) higher. As Spirit continues uphill, scientists are looking for evidence about whether the intensity of water- related alteration increases with elevation or whether there are pockets of more heavily altered rocks and soils scattered throughout the hills. Spirit's panoramic camera took more than 300 individual frames between Feb. 27 and March 2 that are combined into the big picture. Downloading the frames to Earth took several weeks, and processing took additional time. Imaging specialists at Cornell and at NASA's Jet Propulsion Laboratory, Pasadena, Calif., calibrated the color and assembled the image. Spirit and its twin, Opportunity, successfully completed three-month primary missions a year ago. In extended missions since then, they have been exploring at increasing distances from their landing sites. JPL, a division of the California Institute of Technology in Pasadena, manages NASA's Mars Exploration Rover project for NASA's Science Mission Directorate, Washington. Spirit's "Lookout" panorama is also available online at http://www.nasa.gov/vision/universe/solarsystem/mer_main.html [ http://www.nasa.gov/vision/universe/solarsystem/mer_main.html ]and http://marsrovers.jpl.nasa.gov [ http://marsrovers.jpl.nasa.gov/ ] . |

NASA's Opportunity rover looks back at the crater where it landed and spent the first two months of its mission exploring exposed bedrock. This area may have been the shore of a shallow sea. The image is the first 360-degree view from the Mars Exploration Rover Opportunity's new position outside "Eagle Crater," the small crater where the rover landed about two months ago. Scientists are busy analyzing Opportunity's new view of the plains of Meridiani Planum. The plentiful ripples are a clear indication that wind is the primary geologic process currently in effect on the plains. The rover's tracks can be seen leading away from Eagle Crater. At the far left are two depressions - each about a meter (about 3.3 feet) across - that feature bright spots in their centers. One possibility is that the bright material is similar in composition to the rocks in Eagle Crater's outcrop and the surrounding darker material is what's referred to as "lag deposit," or erosional remnants, which are much harder and more difficult to wear away. These twin dimples might be revealing pieces of a larger outcrop that lies beneath. The depression closest to Opportunity is whimsically referred to as "Homeplate" and the one behind it as "First Base." The backshell and parachute that helped protect the rover and deliver it safely to the surface of Mars are also visible near the horizon, at the left of the image. This image was taken by the rover's navigation camera. *Image Credi*: NASA/JPL |

This false-color view combines frames taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity on the rover's 652 through 663 Martian days, or sols (Nov. 23 to Dec. 5, 2005), at the edge of Erebus Crater. The mosaic is presented as a vertical projection. This type of projection provides a true-to-scale overhead view of the rover deck and nearby surrounding terrain. The view here shows outcrop rocks, sand dunes, and other features out to a distance of about 25 meters (82 feet) from the rover. Opportunity examined targets on the outcrop called "Rimrock" in front of the rover, testing the mobility and operation of Opportunity's robotic arm. The view shows examples of the dunes and ripples that Opportunity has been crossing as the rover drives on the Meridiani plains. Image credit: NASA/JPL-Caltech/Cornell |

'McMurdo' Panorama from Spir

'McMurdo' Panorama from Spirit's 'Winter Haven' |
| description |
This 360-degree view, called the "McMurdo" panorama, comes from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Spirit. From April through October 2006, Spirit has stayed on a small hill known as "Low Ridge." There, the rover's solar panels are tilted toward the sun to maintain enough solar power for Spirit to keep making scientific observations throughout the winter on southern Mars. This view of the surroundings from Spirit's "Winter Haven" is presented in approximately true color. Oct. 26, 2006, marks Spirit's 1,000th sol of what was planned as a 90-sol mission. (A sol is a Martian day, which lasts 24 hours, 39 minutes, 35 seconds). The rover has lived through the most challenging part of its second Martian winter. Its solar power levels are rising again. Spring in the southern hemisphere of Mars will begin in early 2007. Before that, the rover team hopes to start driving Spirit again toward scientifically interesting places in the "Inner Basin" and "Columbia Hills" inside Gusev crater. The McMurdo panorama is providing team members with key pieces of scientific and topographic information for choosing where to continue Spirit's exploration adventure. The Pancam began shooting component images of this panorama during Spirit's sol 814 (April 18, 2006) and completed the part shown here on sol 932 (Aug. 17, 2006). The panorama was acquired using all 13 of the Pancam's color filters, using lossless compression for the red and blue stereo filters, and only modest levels of compression on the remaining filters. The overall panorama consists of 1,449 Pancam images and represents a raw data volume of nearly 500 megabytes. It is thus the largest, highest-fidelity view of Mars acquired from either rover. Additional photo coverage of the parts of the rover deck not shown here was completed on sol 980 (Oct. 5 , 2006). The team is completing the processing and mosaicking of those final pieces of the panorama, and that image will be released on the Web shortly to augment this McMurdo panorama view. This beautiful scene reveals a tremendous amount of detail in Spirit's surroundings. Many dark, porous-textured volcanic rocks can be seen around the rover, including many on Low Ridge. Two rocks to the right of center, brighter and smoother-looking in this image and more reflective in infrared observations by Spirit's miniature thermal emission spectrometer, are thought to be meteorites. On the right, "Husband Hill" on the horizon, the rippled "El Dorado" sand dune field near the base of that hill, and lighter-toned "Home Plate" below the dunes provide context for Spirit's travels since mid-2005. Left of center, tracks and a trench dug by Spirit's right-front wheel, which no longer rotates, have exposed bright underlying material. This bright material is evidence of sulfur-rich salty minerals in the subsurface, which may provide clues about the watery past of this part of Gusev Crater. Spirit has stayed busy at Winter Haven during the past, six months even without driving. In addition to acquiring this spectacular panorama, the rover team has also acquired significant new assessments of the elemental chemistry and mineralogy of rocks and soil targets within reach of the rover's arm. The team plans soon to have Spirit drive to a very nearby spot on Low Ridge to access different rock and soil samples while maintaining a good solar panel tilt toward the sun for the rest of the Martian winter. Despite the long span of time needed for acquiring this 360-degree view -- a few images at a time every few sols over a total of 119 sols because the available power was so low -- the lighting and color remain remarkably uniform across the mosaic. This fact attests to the repeatability of wintertime sols on Mars in the southern hemisphere. |

Victoria Crater' at Meridian

Victoria Crater' at Meridiani Planum |
| date |

| 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.

JPL, 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 & Technologies Corporation and is operated by the University of Arizona. Image Credit: NASA/JPL/UA |

Mars Exploration Rover "Spirit" Launches |

| description |
Amid billows of smoke and steam, the Delta II rocket with its Mars Exploration Rover (MER-A) payload lifts off the pad on time at 1:58 p.m. EDT from Launch Complex 17-A, Cape Canaveral Air Force Station. MER-A, known as "Spirit," is the first of two rovers being launched to Mars. When the two rovers arrive at the red planet in 2004, they will bounce to airbag-cushioned landings at sites offering a balance of favorable conditions for safe landings and interesting science. The rovers see sharper images, can explore farther and examine rocks better than anything that has ever landed on Mars. The designated site for the MER-A mission is Gusev Crater, which appears to have been a crater lake. The second rover, MER-B, is scheduled to launch June 25. *Image Credit*: NASA |

Opportunity's Second Martian

Opportunity's Second Martian Birthday at Cape Verde |
| date |
10.20.2007 |
| description |
A promontory nicknamed "Cape Verde" can be seen jutting out from the walls of Victoria Crater in this approximate true-color picture taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity. The rover took this picture on martian day, or sol, 1329 (Oct. 20, 2007), more than a month after it began descending down the crater walls - and just 9 sols shy of its second Martian birthday on sol 1338 (Oct. 29, 2007). Opportunity landed on the Red Planet on Jan. 25, 2004. That's nearly four years ago on Earth, but only two on Mars because Mars takes longer to travel around the sun than Earth. One Martian year equals 687 Earth days. The overall soft quality of the image, and the "haze" seen in the lower right portion, are the result of scattered light from dust on the front sapphire window of the rover's camera. This view was taken using three panoramic-camera filters, admitting light with wavelengths centered at 750 nanometers (near infrared), 530 nanometers (green) and 430 nanometers (violet).
