The Mars Surveyor 2001 Lande
…
| Description |
The Mars Surveyor 2001 Lander is scheduled for launch on April 10, 2001. It will land on Mars on Jan. 22, 2002, if launched on schedule. The 2001 Lander will carry an imager to take pictures of the surrounding terrain during its' rocket-assisted descent to the surface. The descent imaging camera will provide images of the landing site for geologic analyses, and will aid planning for initial operations and traverses by the rover. The 2001 Lander will also be a platform for instruments and technology experiments designed to provide key insights to decisions regarding successful and cost-effective human missions to Mars. Hardware on the Lander will be used for an in-situ demonstration test of rocket propellant production using gases in the Martian atmosphere. Other equipment will characterize the Martian soil properties and surface radiation environment. |

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

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

Color View of Eros' Saddle

Color View of Eros' Saddle |
| description |
Color imaging of Eros from the NEAR Shoemaker spacecraft has shown the asteroid's color variations are very subdued when compared to those of other planetary bodies, such as Mars. However, both the imager and the near-infrared spectrometer have detected discernible color differences between parts of the asteroid. One location on Eros with distinctive color is the eastern side of the 'saddle.' This color composite image of that region was taken April 2, 2000, from an orbital altitude of 201 kilometers (125 miles). In this false color representation, the red and green image planes were taken in different wavelengths of infrared light, and the blue image plane was taken in blue light. NEAR scientists interpret the bright and greenish-gray appearing regions near the rim of the saddle to represent relatively fresh exposures of subsurface soil. In contrast, the pinkish looking soil covering other areas is thought to have been modified by exposure to small impacts and the solar wind. Built and managed by The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, NEAR was the firstspacecraft launched in NASA's Discovery Program of low-cost, small-scale planetary missions.

Close-Up of Sol 24 Sunset |
| description |
This is a close-up of the sunset on Sol 24 as seen by the Imager for Mars Pathfinder. The red sky in the background and the blue around the Sun are approximately as they would appear to the human eye. The color of the Sun itself is not correct -- the Sun was overexposed in each of the 3 color images that were used to make this picture. The true color of the Sun itself may be near white or slightly bluish. Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

This animation, composed of four images taken by the front hazard-identification camera on the Mars Exploration Rover Spirit, shows the rover stretching out its robotic arm, or instrument deployment device. This is the first use of the arm on Mars to deploy the microscopic imager, one of four geological instruments located on the arm. The first frame shows a clear view of the martian surface in front of the rover before the arm was successfully deployed early Friday morning. The subsequent frames show the arm emerging from its stowed position beneath the "front porch" of the rover body, reaching out, and using the microscopic imager to take close-up images of the martian soil. *Image Credit*: NASA/JPL/US Geological Survey |

Mars Kicks Up the Dust as it Makes Closest Approach to Earth |
| General Information |
What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. NASA's Hubble Space Telescope snapped this picture of Mars on October 28, within a day of its closest approach to Earth on the night of October 29. The large regional dust storm appears as the brighter, redder cloudy region in the middle of the planet's disk. This storm, which measures 930 miles (1500 km) has been churning in the planet's equatorial regions for several weeks now, and it is likely responsible for the reddish, dusty haze and other dust clouds seen across this hemisphere of the planet. Hubble's Advanced Camera for Surveys High Resolution Imager took this image when the red planet was 43 million miles (69 million km) from Earth. Mars won't be this close again to Earth until 2018. Mars is now in its warmest months, closest to the Sun in its orbit, resulting in a smaller than normal south polar ice cap which has largely sublimated with the approaching summer. |

Hubble's Advanced Camera for Surveys High Resolution Imager took this image when the red planet was 43 million miles (69 million km) from Earth. Mars won't be this close again to Earth until 2018. Mars is now in its warmest months, closest to the Sun in its orbit, resulting in a smaller than normal south polar ice cap which has largely sublimated with the approaching summer. |

Hubble Observes Surface of Titan |
| Description |
Laboratory and managed by the Goddard Spaced Flight Center for NASA's Office of Space Science. This image and other images and data received from the Hubble Space Telescope are posted on the World Wide Web on the Space Telescope Science Institute home page at URL http://oposite.stsci.edu/pubinfo/, Scientists for the first time have made images of the surface of Saturn's giant, haze-shrouded moon, Titan. They mapped light and dark features over the surface of the satellite during nearly a complete 16-day rotation. One prominent bright area they discovered is a surface feature 2,500 miles across, about the size of the continent of Australia. Titan, larger than Mercury and slightly smaller than Mars, is the only body in the solar system, other than Earth, that may have oceans and rainfall on its surface, albeit oceans and rain of ethane-methane rather than water. Scientists suspect that Titan's present environment -- although colder than minus 289 degrees Fahrenheit, so cold that water ice would be as hard as granite -- might be similar to that on Earth billions of years ago, before life began pumping oxygen into the atmosphere. Peter H. Smith of the University of Arizona Lunar and Planetary Laboratory and his team took the images with the Hubble Space Telescope during 14 observing runs between Oct. 4 - 18. Smith announced the team's first results last week at the 26th annual meeting of the American Astronomical Society Division for Planetary Sciences in Bethesda, Md. Co-investigators on the team are Mark Lemmon, a doctoral candidate with the UA Lunar and Planetary Laboratory, John Caldwell of York University, Canada, Larry Sromovsky of the University of Wisconsin, and Michael Allison of the Goddard Institute for Space Studies, New York City. Titan's atmosphere, about four times as dense as Earth's atmosphere, is primarily nitrogen laced with such poisonous substances as methane and ethane. This thick, orange, hydrocarbon haze was impenetrable to cameras aboard the Pioneer and Voyager spacecraft that flew by the Saturn system in the late 1970s and early 1980s. The haze is formed as methane in the atmosphere is destroyed by sunlight. The hydrocarbons produced by this methane destruction form a smog similar to that found over large cities, but is much thicker. Smith's group used the Hubble Space Telescope's WideField/Planetary Camera 2 at near-infrared wavelengths (between .85 and 1.05 microns). Titan's haze is transparent enough in this wavelength range to allow mapping of surface features according to their reflectivity. Only Titan's polar regions could not be mapped this way, due to the telescope's viewing angle of the poles and the thick haze near the edge of the disk. Their image-resolution (that is, the smallest distance seen in detail) with the WFPC2 at the near-infrared wavelength is 360 miles. The 14 images processed and compiled into the Titan surface map were as "noise" free, or as free of signal interference, as the space telescope allows, Smith said. Titan makes one complete orbit around Saturn in 16 days, roughly the duration of the imaging project. Scientists have suspected that Titan's rotation also takes 16 days, so that the same hemisphere of Titan always faces Saturn, just as the same hemisphere of the Earth's moon, always faces the Earth. Recent observations by Lemmon and colleagues at the University of Arizona confirm this true. It's too soon to conclude much about what the dark and bright areas in the Hubble Space Telescope images are -- continents, oceans, impact craters or other features, Smith said. Scientists have long suspected that Titan's surface was covered with a global ehtane-methane ocean. The new images show that there is at least some solid surface. Smith's team made a total 50 images of Titan last month in their program, a project to search for small scale features in Titan's lower atmosphere and surface. They have yet to analyze images for information about Titan's clouds and winds. That analysis could help explain if the bright areas are major impact craters in the frozen water ice-and-rock or higher-altitude features. The images are important information for the Cassini mission, which is to launch a robotic spacecraft on a 7-year journey to Saturn in October 1997. About three weeks before Cassini's first flyby of Titan, the spacecraft is to release the European Space Agency's Huygens Probe to parachute to Titan's surface. Images like Smith's team has taken of Titan can be used to identify choice landing spots - - and help engineers and scientists understand how Titan's winds will blow the parachute through the satellite's atmosphere. UA scientists play major roles in the Cassini mission: Carolyn C. Porco, an associate professor at the Lunar and Planetary Laboratory, leads the 14-member Cassini Imaging Team. Jonathan I. Lunine, also an associate professor at the lab, is the only American selected by the European Space Agency to be on the three-member Huygens Probe interdisciplinary science team. Smith is a member of research professor Martin G. Tomasko's international team of scientists who will image the surface of Titan in visible light and in color with the Descent Imager/Spectral Radiometer, one of five instruments in the Huygens Probe's French, German, Italian and U.S. experiment payload. Senior research associate Lyn R. Doose is also on Tomasko's team. Lunine and LPL professor Donald M. Hunten are members of the science team for another U.S. instrument on that payload, the gas chromatograph mass spectrometer. Hunten was on the original Cassini mission science definition team back in 1983. PHOTO CAPTION: Four global projections of the HST Titan data, separated in longitude by 90 degrees. Upper left: hemisphere facing Saturn. Upper right: leading hemisphere (brightest region). Lower left: the hemisphere which never faces Saturn. Lower right: trailing hemisphere. Not that these assignments assume that the rotation is synchronous. The imaging team says its data strongly support this assumption -- a longer time baseline is needed for proof. The surface near the poles is never visible to an observer in Titan's equatorial plane because of the large optical path. The Wide Field/Planetary Camera 2 was developed by the Jet Propulsion |

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 |

Mars Reconnaissance Orbiter Adjusts Angle of Orbit |
| Description |
This artist's concept of NASA's Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet. The large silver circular feature above the spacecraft bus is the high-gain antenna, the spacecraft's main means of communicating with Earth. The long, thin pole behind the bus is the antenna for the Shallow Subsurface Radar instrument (SHARAD). Seeking liquid or frozen water, this instrument will probe the subsurface using radar waves at frequencies of 15 to 25 megahertz, "seeing" in the first few hundred feet (up to 1 kilometer) of Mars' crust. The large instrument covered in black thermal blanketing in the center is the High Resolution Imaging Science Experiment camera (HiRISE). It will provide the highest-resolution images ever taken from Mars orbit. The Electra telecommunications package is the gold-colored instrument directly left of the high-resolution camera. It will act as a communications relay and navigation aid for Mars spacecraft. To the right of the high-resolution camera is the Context Imager (CTX). Credit: NASA/JPL |

Calibration View of Earth and the Moon by Mars Color Imager |
| Description |
*View Animation (17 kB)* Three days after the Mars Reconnaissance Orbiter's Aug. 12, 2005, launch, the spacecraft was pointed toward Earth and the Mars Color Imager camera was powered up to acquire a suite of images of Earth and the Moon. When it gets to Mars, the Mars Color Imager's main objective will be to obtain daily global color and ultraviolet images of the planet to observe martian meteorology by documenting the occurrence of dust storms, clouds, and ozone. This camera will also observe how the martian surface changes over time, including changes in frost patterns and surface brightness caused by dust storms and dust devils. The purpose of acquiring an image of Earth and the Moon just three days after launch was to help the Mars Color Imager science team obtain a measure, in space, of the instrument's sensitivity, as well as to check that no contamination occurred on the camera during launch. Prior to launch, the team determined that, three days out from Earth, the planet would only be about 4.77 pixels across, and the Moon would be less than one pixel in size, as seen from the Mars Color Imager's wide-angle perspective. If the team waited any longer than three days to test the camera's performance in space, Earth would be too small to obtain meaningful results. The Earth and Moon images were acquired by turning Mars Reconnaissance Orbiter toward Earth, then slewing the spacecraft so that the Earth and Moon would pass before each of the five color and two ultraviolet filters of the Mars Color Imager. The distance to the Moon was about 1,440,000 kilometers (about 895,000 miles), the range to Earth was about 1,170,000 kilometers (about 727,000 miles). This view combines a sequence of frames showing the passage of Earth and the Moon across the field of view of a single color band of the Mars Color Imager. As the spacecraft slewed to view the two objects, they passed through the camera's field of view. Earth has been saturated white in this image so that both Earth and the Moon can be seen in the same frame. The Sun was coming from the left, so Earth and the Moon are seen in a quarter phase. Earth is on the left. The Moon appears briefly on the right. The Moon fades in and out, the Moon is only one pixel in size, and its fading is an artifact of the size and configuration of the light-sensitive pixels of the camera's charge-coupled device (CCD) detector.

View of Argyre Basin from Test of Mars Color Image |
| Description |
, three views acquired by MARCI are compared to a color composite of two views acquired about four hours later by the wide-angle imager of Mars Orbiter Camera (MOC) on NASA's Mars Global Surveyor spacecraft. The MARCI imaging occurred during the morning on Mars, while the MOC observations were made at about 2 p.m. local solar time. The region of Mars imaged by MARCI was south of the Valles Marineris. It includes the Argyre Basin's interior plains, Argyre Planitia, and mountains forming the basin rim, Nereidum Montes to the northwest (middle of images) and Charitum Montes to the southeast (bottom of images). The color composite from MARCI differs from the MOC wide-angle color composite because, to create a color image with MOC data, camera-team members synthesize (fake) a green channel by adding the red and blue channels together and dividing by two. The slightly greenish tint of the MARCI image shows that the approximation used for MOC images underestimates the amount of green. The test image labeled 260 nm shows how the planet appears at an ultraviolet (UV) waveband of 260 nanometers, where ozone absorbs the UV light. Relatively darker areas in this band normally will indicate the presence of ozone, and relatively lighter areas will indicate the absence of ozone. Water vapor in Mars' atmosphere is in an inverse relationship with ozone, where there is more of one, there is less of the other. So, lighter areas in images can be used to track water vapor. The term "relatively" is used here because Mars itself is very dark in the UV owing to absorption of UV light by iron-bearing minerals, and sunlight is deficient in UV relative to visible light, so in general Mars will always look dark in the UV. A second UV band on MARCI (not shown in the figure above) at a longer wavelength allows these differences to be quantified. The MOC wide-angle image shows wispy, light water-ice clouds to the northwest of Argyre in the afternoon, but researchers cannot yet correlate these clouds with the UV information from MARCI, especially because the times of day are different. When in its final mapping orbit, Mars Reconnaissance Orbiter will view the same area as Mars Global Surveyor separated by only one hour, and such correlations will be much more direct. For more details of how MARCI images are acquired and processed, see the companion release, MARCI2-3 [ http://www.msss.com/others/marci_release/marci_detail/index.html ], and be certain to examine the 15.6 Mbyte animated GIF movie, . The pictures shown here are the first views of Mars acquired by the Mars Color Imager on Mars Reconnaissance Orbiter. This is a re-flight of a similar instrument that was aboard the Mars Climate Orbiter, which was lost in September 1999 during its orbit insertion activity. In the primary science phase of the Mars Reconnaissance Orbiter, MARCI will routinely acquire daily global maps of the planet. These data will be used to help track storms, monitor clouds and water vapor, and track seasonal changes in surface albedo (bright and dark) patterns and the polar caps. Credit: NASA/JPL/MSSS, The Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter acquired a seven-band color, wide-angle view of Mars on March 24, 2006, as part of a checkout of the orbiter's payload. This image shows a color composite made from the MARCI red, green, and blue bands. The view looks northward and includes the large Argyre Basin in Mars' southern hemisphere. One use of the test imaging is an opportunity to fine-tune calibrations used for processing the separate bands into "true" color -- as it would appear to a human eye looking down from orbit. Further calibration will be needed. Regular use of MARCI and the other science instruments on Mars Reconnaissance Orbiter will begin in autumn 2006, after the spacecraft's orbit has been reshaped to a nearly circular, low-altitude path.*Full Res JPG (236 kB)* The March 24 test produced images from each color band.

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.

Mars Rovers Battle Severe Dust Storm |
| Description |
Since late June 2007, Mars has been having a series of regional dust storms. The dust raised by these individual storms has obscured most of the planet over the past few weeks. The two maps shown here are mosaics of images acquired by the Mars Reconnaissance Orbiter (MRO) Mars Color Imager (MARCI) on two days separated by about 3 and a half weeks. The first, on 22 June, shows that there was a dust storm occurring near the east end of the Valles Marineris trough system (left of the label for "Opportunity" in the map). This was the first in the series of storms. The second mosaic shows how Mars appeared on 17 July, after dust was lofted high into the atmosphere by several regional storms and countless smaller, local dust storms. Each map was constructed from 13 pole-to-pole image swaths at red, green, and blue wavelengths acquired by the MRO MARCI. The maps are simple cylindrical projections, with north at the top and south at the bottom. Each image swath was acquired at about 3 p.m. local time on Mars over the course of 13 orbits. The black gaps occur in the MARCI data at places where the MRO spacecraft was slewed east or west to point its instruments at a specific target of scientific interest. The north polar region is not shown because winter began on 4 July and the north polar region is in wintertime darkness. Key features labeled on the maps include the Tharsis Montes and Olympus Mons volcanoes, the Hellas impact basin, Noachis Terra, Sinus Meridiani, and the two Mars Exploration Rover (MER) landing sites, Opportunity and Spirit. The dust storms, and the planet-encircling dust veil they generated, has greatly reduced the amount of sunlight available to run the two solar-powered rovers., This sequence of Mars Reconnaissance Orbiter (MRO) Mars Color Imager (MARCI) daily mosaics shows some of the dust storm activity that occurred near the Mars Exploration Rover (MER) Opportunity landing site between 21 June 2007 and 18 July 2007. The Opportunity rover is located near the martian prime meridian and equator. The top and middle rows of images show the first six days of dust storm activity near the rover site as dust advanced from the west to the south and passed south of the rover over the course of a week. By the end of that first week, storm activity strengthened and continued to move east, eventually passing over nearly half of the martian southern hemisphere. Other storms spawned by this atmospheric disturbance affected the MER Spirit rover on the other side of the planet, while new storms developed, approached, and affected Opportunity. The bottom three images show dust activity over the MER Opportunity site on 3, 14, and 18 July. By 19 July, most of the martian surface was obscured by the dust lofted from these storms. As with previous large dust-raising events on Mars, once the active storms die down, many weeks to months will pass before the dust settles out and the atmosphere clears. The white circle indicates the location of the Opportunity landing site, the black gaps are caused by slewing the spacecraft east or west to image specific science targets, and north in each picture is toward the top, west is to the left.

| Original Caption Released with Image |
This image is a traverse map, illustrating Spirit's path over the last 45 sols. When the rover reached the point called "Laguna Hollow," it had driven 131 meters (430 feet) from Columbia Memorial Station. The rover heading is 45 degrees to the northeast. On the horizon behind the lander looms the landmark informally named "Grissom Hill." Over the relatively flat traverse, Spirit has made observations of rocks such as "Adirondack" and utilized the tools on its arm to investigate soil in several locations. Spirit stayed at "Laguna Hollow" for 3 sols, dug a trench and observed the floor and wall of it with three of the instruments on its arm: the Moessbauer spectrometer, the alpha particle X-ray spectrometer and the microscopic imager. Spirit is about halfway to the edge of the crater dubbed "Bonneville. |
