Western Arcadia Planitia |
| Description |
This is a Mars Odyssey visible color image of an unnamed crater in western Arcadia Planitia (near 39 degrees N, 179 degrees E). The crater shows a number of interesting internal and external features that suggest that it has undergone substantial modification since it formed. These features include concentric layers and radial streaks of brighter, redder materials inside the crater, and a heavily degraded rim and ejecta blanket. The patterns inside the crater suggest that material has flowed or slumped towards the center. Other craters with features like this have been seen at both northern and southern mid latitudes The distribution of these kinds of craters suggests the possible influence of surface or subsurface ice in the formation of these enigmatic features. The image was taken on September 29, 2002 during late northern spring. This is an approximate true color image, generated from a long strip of visible red (654 nm), green (540 nm), and blue (425 nm) filter images that were calibrated using a combination of pre-flight measurements and Hubble images of Mars. The colors appear perhaps a bit darker than one might expect, this is most likely because the images were acquired in late afternoon (roughly 4:40 p.m. local solar time) and the low Sun angle results in an overall darker surface.

Mars Ice Age, Simulated |
| Description |
Infrared imaging from NASA's Mars Odyssey spacecraft shows signs of layering exposed at the surface in a region of Mars called Terra Meridiani. The brightness levels show daytime surface temperatures, which range from about minus 20 degrees to zero degrees Celsius (minus 4 degrees to 32 degrees Fahrenheit). Many of the temperature variations are due to slope effects, with sun-facing slopes warmer than shaded slopes. However, several rock layers can be seen to have distinctly different temperatures, indicating that physical properties vary from layer to layer. These differences suggest that the environment on this part of Mars varied through time as these layers were formed. The image is a mosaic combining four exposures taken by the thermal emission imaging system aboard Odyssey during the first two months of the Odyssey mapping mission, which began in February 2002. The area shown is about 120 kilometers (75 miles) across, at approximately 358 degrees east (2 degrees west) longitude and 3 degrees north latitude. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C.

Odyssey/Ganges |
| Description |
These Mars Odyssey images show layered deposits located on the floor of Ganges Chasma, part of the Valles Marineris canyon system, in both infrared (left) and visible (right) wavelengths. The images were acquired simultaneously by the thermal emission imaging system on March 17, 2002. The box shows where the visible image is located wthin the infrared image. The infrared image displays variations in surface temperature where bright tones indicate warmer surfaces and dark tones are cooler ones. Dramatic layering can be seen throughout the central deposit in both the infrared and visible images. Different styles of erosion are shown in these different layers, suggesting that Mars was subject to changing environments during its history. The infrared image has a resolution of 100 meters (328 feet) per pixel and is 32 kilometers (20 miles) wide. The visible image has a resolution of 18 meters per pixel and is approximately 18 kilometers (11 miles) wide. Pixel brightness in the infrared image is controlled by the temperature of the surface, which is in turn depend on how much Sun the area gets. Hence, dark units will heat up during the day and appear bright in the infrared. Conversely, visibly bright areas will not heat up as much and will appear dark in the infrared image. The images are centered at 7.1 degrees south latitude and 310.4 degrees east longitude.

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

Data from Odyssey's Martian radiation environment experiment show that the radiation dose equivalent at Mars is two to three times greater than that aboard the International Space Station. The differences are primarily due to the magnetic field surrounding the Earth, which provides considerable shielding to astronauts in orbit. Mars lacks a strong magnetic field and is therefore more exposed to the harshest elements of space radiation.

| Title |
The So-Called "Face on Mars |
| Original Caption Released with Image |
(Released 13 April 2002) The Science The so called "Face on Mars" can be seen slightly above center and to the right in this THEMIS visible image. This 3-km long knob, located near 10° N, 40° W (320° E), was first imaged by the Viking spacecraft in the 1970's and was seen by some to resemble a face carved into the rocks of Mars. Since that time the Mars Orbiter Camera on the Mars Global Surveyor spacecraft has provided detailed views of this hill that clearly show that it is a normal geologic feature with slopes and ridges carved by eons of wind and downslope motion due to gravity. A similar-size hill in Phoenix, Arizona resembles a camel lying on the ground, and Phoenicians whimsically refer to it as Camelback Mountain. Like the hills and knobs of Mars, however, Camelback Mountain was carved into its unusual shape by thousands of years of erosion. The THEMIS image provides a broad perspective of the landscape in this region, showing numerous knobs and hills that have been eroded into a remarkable array of different shapes. Many of these knobs, including the "Face", have several flat ledges partway up the hill slopes. These ledges are made of more resistant layers of rock and are the last remnants of layers that once were continuous across this entire region. Erosion has completely removed these layers in most places, leaving behind only the small isolated hills and knobs seen today. Many of the hills and ridges in this area also show unusual deposits of material that occur preferentially on the cold, north-facing slopes. It has been suggested that these deposits were "pasted" on the slopes, with the distinct, rounded boundary on their upslope edges being the highest remaining point of this pasted-on layer. In several locations, such as in the large knob directly south of the "Face", these deposits occur at several different heights on the hill. This observation suggests the layer once draped the entire knob and has since been removed from all but the north-facing slopes. The presence of water ice in these layers is a likely possibility to account for their preservation only on the colder surfaces. Alternatively, these unique features could be the result of the slow downslope motion of the surface layer, possibly enhanced by the presence of ground ice. One argument against downslope motion is the observation that the uppermost rounded boundary of these layers typically occurs at approximately the same distance below the ridge crest. This would suggest the (seemingly) unlikely possibility that all of these layers had moved downslope the same amount regardless of where they are located. In either case, ground ice likely plays an important role in the formation and preservation of these deposits because they only occur on the cold slopes facing away from the Sun where ground ice is more stable and may still be present today. The Story Nature is an imaginative artist, creating all kinds of wonderful landforms, cloud shapes, and other patterned, features that remind people of familiar things in our lives. We see a "man in the moon" when it is full in the night sky, and dream of a dromedary-dotted desert when coming upon Arizona's Camelback Mountain or Colorado's "Kissing Camels" in the "Garden of the Gods." Near Ludlow, California, a lonely prospector once noticed that the appealing outline of the mountains resembled a reclining woman, and named the place Sleeping Beauty. And this naming delight isn't limited to Earth. The Mars Pathfinder mission team couldn't help but name the rocks at the landing site, including a bear-headed-looking one named Yogi. Part of the fun of exploration is not just visiting a strange world, but relating to it in human terms. On Mars, we've already seen a valentine heart-shaped crater, a happy-faced crater, and even a murky and mysterious "face" on Mars. This face (seen here about halfway down the image and to the right) is really just a hill with slopes and ridges that are shadowed in a way that can sometimes resemble a face from far away. The first picture of this area was taken by the Viking spacecraft in the 1970s, and people have been intrigued ever since. However, orbiter camera technologies have actually become so good in providing a clear view of the hill that it's almost a disappointment to see how normal an eroded hill this well-liked feature is. Well, disappointing unless you're a geologist, that is! This whole area is, in fact, a geologist's dream. Erosion has been Nature's sculptor throughout the area, and all kinds of remarkably shaped knobs and hills speckle the region. While their shapes are fun to contemplate, it's no mystery to geologists how they formed. Several flat ledges part way up the slopes of these hills are made of layers of rock that stand strong against erosion's relentless carving. Less resistant layers in the region have eroded away completely in most places, leaving behind only the small, isolated hills and knobs we see today. Don?t think everything in this scene is easily understandable, however. What captures the attention of scientists is a bunch of unusual deposits of material on the cold, north-facing slopes of the hills. Did Nature mix some Martian dirt and ice from the planet's "pallet," and then "paste" on a slightly cemented deposit over the northern slopes? Or did an upper layer of material slowly creep downslope over time, carried by the movement of ice? Ground ice, in this case, has probably been more of a preserver than an eroder, keeping a record of the formation and existence of these deposits over time. Geologists are grateful for that peek into the Martian past and the chance to study it in-depth. |

However, orbiter camera technologies have actually become so good in providing a clear view of the hill that it's almost a disappointment to see how normal an eroded hill this well-liked feature is. Well, disappointing unless you're a geologist, that is! This whole area is, in fact, a geologist's dream. Erosion has been Nature's sculptor throughout the area, and all kinds of remarkably shaped knobs and hills speckle the region. While their shapes are fun to contemplate, it's no mystery to geologists how they formed. Several flat ledges part way up the slopes of these hills are made of layers of rock that stand strong against erosion's relentless carving. Less resistant layers in the region have eroded away completely in most places, leaving behind only the small, isolated hills and knobs we see today. Don?t think everything in this scene is easily understandable, however. What captures the attention of scientists is a bunch of unusual deposits of material on the cold, north-facing slopes of the hills. Did Nature mix some Martian dirt and ice from the planet's "pallet," and then "paste" on a slightly cemented deposit over the northern slopes? Or did an upper layer of material slowly creep downslope over time, carried by the movement of ice? Ground ice, in this case, has probably been more of a preserver than an eroder, keeping a record of the formation and existence of these deposits over time. Geologists are grateful for that peek into the Martian past and the chance to study it in-depth. |

Layered Deposits in Western Candor Chasma |
| Original Caption Released with Image |
The layered deposits in this Valles Marineris canyon are heavily eroded by the wind into an impressive array of yardangs and swirling patterns of layers. The origin of the deposits remains a mystery. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later 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 (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey 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. Image information: VIS instrument. Latitude -5.2, Longitude 282.7 East (77.3 West). 19 meter/pixel resolution. |
