Valles Marineris: The Grand …
Title Valles Marineris: The Grand Canyon of Mars
Explanation The largest canyon in the Solar System [ http://www.nineplanets.org/overview.html ] cuts a wide swath across the face of Mars [ http://www.nineplanets.org/mars.html ]. Named Valles Marineris [ http://astrogeology.usgs.gov/Projects/VallesMarineris/ ], the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon [ http://en.wikipedia.org/wiki/Grand_Canyon ] in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris [ http://en.wikipedia.org/wiki/Valles_Marineris ] remains unknown, although a leading hypothesis holds that it started as a crack [ http://antwrp.gsfc.nasa.gov/apod/ap980310.html ] billions of years ago as the planet cooled [ http://helio.estec.esa.nl/intermarsnet/redreport/node20.html ]. Recently [ http://antwrp.gsfc.nasa.gov/apod/ap020531.html ], several geologic processes have been identified in the canyon [ http://www.windows.ucar.edu/cgi-bin/tour.cgi?link=/mars/interior/Valles_Marineris.html&sw=false&sn=4444&d=/mars/interior&edu=mid&br=graphic&back=/mars/exploring/MGS_altimeter_OMons.html&cd=false&tour=&fr=f ]. The above mosaic [ http://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-mars.html ] was created [ http://nssdc.gsfc.nasa.gov/photo_gallery/caption/marsglobe1.txt ] from over 100 images of Mars [ http://antwrp.gsfc.nasa.gov/apod/mars.html ] taken by Viking [ http://pds.jpl.nasa.gov/planets/welcome/viking.htm ] Orbiters in the 1970s.

Topographical Mars
Title Topographical Mars
Explanation Contrasting colors trace changing elevations in this new high-resolution topographic map of Mars [ http://pao.gsfc.nasa.gov/gsfc/spacesci/pictures/mola/mars3d.htm ]. Just released [ ftp://pao.gsfc.nasa.gov/pub/PAO/Releases/1999/99-71.txt ], the data were gathered in 1998 and 1999 by the Mars Orbiter Laser Altimeter [ http://ltpwww.gsfc.nasa.gov/tharsis/mola.html#Introduction ] (MOLA) onboard the Mars Global Surveyor spacecraft. The martian topography is seen to range over 19 miles between the highest volcanic peaks (white) and the lowest regions (purple). Along with the striking difference [ http://www.msss.com/http/ps/di.html ] between the Red Planet's [ http://www.uapress.arizona.edu/online.bks/mars/contents.htm ] low northern hemisphere (top) and high southern regions, one of the most noticeable features on the map [ http://www-pdsimage.wr.usgs.gov/PDS/public/mapmaker/mapmkr.htm ] is the large blue-purple southern depression corresponding to the Hellas basin. Likely the result of an asteroid impact, Mars' deepest basin is about 1300 miles across making it one of the largest impact features [ http://antwrp.gsfc.nasa.gov/apod/ap960906.html ] in the Solar System. Explorations [ http://antwrp.gsfc.nasa.gov/apod/ap981216.html ] of MOLA's rich topographic database are expected to produce insights into water flows and the geologic history [ http://helio.estec.esa.nl/intermarsnet/redreport/node20.html ] of Mars.

title 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. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The thermal emission imaging system was provided by Arizona State University, Tempe. Lockheed Martin Astronautics, Denver, is the prime contractor for the project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.

Description *Full Res(984 kB)**High View of Melas* Soaring high above Valles Marineris, the "Grand Canyon of Mars," viewers look down and catch a sight resembling parts of the desert West of the United States, but on a vastly greater scale. Here the canyon averages over a hundred miles wide, and its floor is heaped with rocks, sediments, and landslide debris. Within the canyon walls lie possibly hundreds of layers filling many pages of Mars' geologic record. This scene comes from "Flight Through Mariner Valley," an exciting video produced for NASA by the Jet Propulsion Laboratory. The video takes viewers on a simulated flight into Valles Marineris, where they explore its scenic wonders as their imaginary scout ship dives low over landslides and races through winding canyons. The video features high-resolution images from Arizona State University's Thermal Emission Imaging System multi-band camera on NASA's Mars Odyssey. The images, which show details as small as 300 meters (1,000 feet) across, were taken at infrared wavelengths during the Martian daytime. Scientists joined hundreds of individual frames from the camera into a giant mosaic, then colored the mosaic to approximate how Mars would appear to the human eye. To give the mosaic depth and height, moviemakers fitted it to a computerized topographic model for Valles Marineris. This was developed using hundreds of thousands of altitude measurements by the Mars Orbiter Laser Altimeter, an instrument on NASA's Mars Global Surveyor spacecraft.

title First HiRISE Image of Mars: Topographic Model from Photoclinometry
Description http://www.nasa.gov/mro [ http://www.nasa.gov/mro ] or http://HiRISE.lpl.arizona.edu [ http://HiRISE.lpl.arizona.edu ]. For information about NASA and agency programs on the Web, visit: http://www.nasa.gov [ http://www.nasa.gov ]. 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/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.

Description *Full Res(683 kB)**Winding Side Canyon (Louros Valles)* Viewers experience roller-coaster twists and turns as they fly up a winding tributary valley that feeds into Valles Marineris, the "Grand Canyon of Mars." Geologists think channels such as these were carved by water as it escaped through faults and cracks in the subsurface. This caused the ground above it to collapse, leaving a meandering channel that resembles a stream valley on Earth. This scene comes from "Flight Through Mariner Valley," an exciting video produced for NASA by the Jet Propulsion Laboratory. The video takes viewers on a simulated flight into Valles Marineris, where they explore its scenic wonders as their imaginary scout ship dives low over landslides and races through winding canyons.

Description *Full Res (1.3 MB)**Mars Canyon with Los Angeles for Scale* A "Grand Canyon of Mars" slices across the Red Planet near its equator. This canyon -- Valles Marineris, or the Mariner Valley -- is 10 times longer and deeper than Arizona's Grand Canyon, and 20 times wider. As the picture shows, you could drop the whole Los Angeles basin into a small part of Valles Marineris and leave plenty of room to spare. In length, the canyon extends far enough that it could reach across the United States from East Coast to West Coast, while its rim stands more than 25,000 feet high, nearly as tall as Earth's Mount Everest.

Title Light-Toned Bedrock Along Cracks as Evidence of Fluid Alteration
Original Caption Released with Image This enhanced-color image from the High Resolution Imaging Science Experiment Camera on NASA's Mars Reconnaissance Orbiter shows a landscape of sand dunes and buttes among a background of light-toned (tan-colored) bands and dark-toned (blue-colored) bands in the Candor Chasma region of Mars' Valles Marineris canyon system. The scene includes examples of thin dark lines bordered by light-toned bedrock [Figures 2A, 2B, and 2C]. The dark lines are interpreted as fractures, called joints, that were formerly underground but have been exposed at the surface by erosion of overlying material. The light-toned material along the joints is interpreted as features called halos, resulting from mineral alteration (bleaching, cementation or both) of the walls of the fractures by fluid moving through the fractures. The image was acquired on Sept. 30, 2006, during winter in Mars' southern hemisphere, at a local Mars time of 3:29 p.m. It combines separate band passes taken by the High Resolution Imaging Science Experiment in blue-green light, red light and near-infrared light. The scene is illuminated from the west (left) with a solar incidence angle of 58.5 degrees. The image scale is 26 centimeters (10 inches) per pixel, the scale of the red bandpass image. The other bandpasses were acquired with two-by-two pixel binning to 52 centimeters (20 inches) per pixel. The image, in the camera's catalogue as TRA_000836_1740, is centered at 5.7 degrees south latitude, 284.6 degrees east longitude. A locator map [Supplement 2] based on elevation data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor indicates this location in the context of the Candor Chasma region. A full resolution file of this image is available for download by clicking here (82 MB). A subframe of the full image [Figure 1] shows the locations of smaller pull-outs selected for showing details of interest. Supplement 3 shows light-toned and dark-toned layers. Meter-scale dune forms are commonly observed within the dark layers. Also shown are joints and surrounding halos. In contrast to Figure 2, the halos along these joints are laterally more extensive and less localized along the trace of the joint. Supplement 4 shows two streamlined mesas of layered bedrock. The windward slopes of these mesas appear smooth, consistent with wind erosion. Boulders are common along the northwest slopes of the mesas. The horizontal spacing of joints appears to control the lateral dimensions of many of the largest boulders. Supplement 5, shows a high-density population of joints.

The scene is illuminated from the west (left) with a solar incidence angle of 58.5 degrees. The image scale is 26 centimeters (10 inches) per pixel, the scale of the red bandpass image. The other bandpasses were acquired with two-by-two pixel binning to 52 centimeters (20 inches) per pixel. The image, in the camera's catalogue as TRA_000836_1740, is centered at 5.7 degrees south latitude, 284.6 degrees east longitude. A locator map [Supplement 2] based on elevation data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor indicates this location in the context of the Candor Chasma region. A full resolution file of this image is available for download by clicking here (82 MB). A subframe of the full image [Figure 1] shows the locations of smaller pull-outs selected for showing details of interest. Supplement 3 shows light-toned and dark-toned layers. Meter-scale dune forms are commonly observed within the dark layers. Also shown are joints and surrounding halos. In contrast to Figure 2, the halos along these joints are laterally more extensive and less localized along the trace of the joint. Supplement 4 shows two streamlined mesas of layered bedrock. The windward slopes of these mesas appear smooth, consistent with wind erosion. Boulders are common along the northwest slopes of the mesas. The horizontal spacing of joints appears to control the lateral dimensions of many of the largest boulders. Supplement 5, shows a high-density population of joints.

Title MGS Mars Orbiter Laser Altimeter (MOLA) - Mars/Earth Relief Comparison
Original Caption Released with Image Comparison of the cross-sectional relief of the deepest portion of the Grand Canyon (Arizona) on Earth versus a Mars Orbiter Laser Altimeter (MOLA) view of a common type of chasm on Mars in the western Elysium region. The MOLA profile was collected during the Mars Global Surveyor Capture Orbit Calibration Pass on September 15, 1997. The Grand Canyon topography is shown as a trace with a measurement every 295 feet (90 meters) along track, while that from MOLA reflects measurements about every 970 feet (400 meters) along track. The slopes of the steep inner canyon wall of the Martian feature exceed the angle of repose, suggesting relative youth and the potential for landslides. The inner wall slopes of the Grand Canyon are less than those of the Martian chasm, reflecting the long period of erosion necessary to form its mile-deep character on Earth.

Original Caption Released with Image Soaring high above Valles Marineris, the "Grand Canyon of Mars," viewers look down and catch a sight resembling parts of the desert West of the United States, but on a vastly greater scale. Here the canyon averages over a hundred miles wide, and its floor is heaped with rocks, sediments, and landslide debris. Within the canyon walls lie possibly hundreds of layers filling many pages of Mars' geologic record. This scene comes from """Flight Through Mariner Valley," an exciting video produced for NASA by the Jet Propulsion Laboratory. The video takes viewers on a simulated flight into Valles Marineris, where they explore its scenic wonders as their imaginary scout ship dives low over landslides and races through winding canyons. The video features high-resolution images from Arizona State University's Thermal Emission Imaging System multi-band camera on NASA's Mars Odyssey. The images, which show details as small as 300 meters (1,000 feet) across, were taken at infrared wavelengths during the Martian daytime. Scientists joined hundreds of individual frames from the camera into a giant mosaic, then colored the mosaic to approximate how Mars would appear to the human eye. To give the mosaic depth and height, moviemakers fitted it to a computerized topographic model for Valles Marineris. This was developed using hundreds of thousands of altitude measurements by the Mars Orbiter Laser Altimeter, an instrument on NASA's Mars Global Surveyor spacecraft.
