This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows an example from southern Acidalia near 23.0°N, 39.6°W. The dominant winds blow from the upper right (northeast) toward the lower left (southwest). The picture covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.

The channel formation is surface controlled, while the lava-tube creation is mainly structurally controlled.	Released 30 March 2004The Odyssey spacecraft has completed a full Mars year of observations of the red planet. For the next several weeks the Image of the Day will look back over this first mars year. It will focus on four themes: 1) the poles - with the seasonal changes seen in the retreat and expansion of the caps; 2) craters - with a variety of morphologies relating to impact materials and later alteration, both infilling and exhumation; 3) channels - the clues to liquid surface flow; and 4) volcanic flow features. While some images have helped answer questions about the history of Mars, many have raised new questions that are still being investigated as Odyssey continues collecting data as it orbits Mars.The image shows an area in Elysium Planitia near Isidis Planitia. It was acquired May 17, 2002 during northern spring. The local time is 3:30pm. The image shows channels and collapsed lava-tubes. The channel formation is surface controlled, while the lava-tube creation is mainly structurally controlled.Image information: VIS instrument.

Context imageToday's VIS image shows an unnamed crater in Terra Sabaea. The central peak of the crater has been surrounded by a deposit of material that is easily eroded, as shown by the wind eroded features on the south side of the deposit. Several craters in this region have large deposits of materials on the crater floor. These deposits postdate the formation of the craters, and have themselves by eroded over time. It is very likely that wind played a roll in the deposition of materials as well as the subsequent erosion.Orbit Number: 93875 Latitude: 7.99639 Longitude: 20.9896 Instrument: VIS Captured: 2023-02-11 23:23Please see the THEMIS Data Citation Note for details on crediting THEMIS images.NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C.

The distinct inverted boat hull-shaped ridges are yardangs formed by wind erosion.	7 December 2004This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows layered outcrops of sediment deposited in southern Chryse Planitia by flow through the Hypanis Valles system in Xanthe Terra. The distinct inverted boat hull-shaped ridges are yardangs formed by wind erosion. These materials are located near 11.9°N, 45.5°W.

https://photojournal.jpl.nasa.gov/catalog/PIA12994	/content/Nasa_Mars_Images/PIA12994_modest.jpg	This image from NASA's Mars Reconnaissance Orbiter shows a portion of the floor in Palos Crater on equatorial Mars. The floor appears bumpy with high-standing layered knobs; most of its terrain is weathering into meter-size (yard-size) polygonal blocks.	This image shows a portion of the floor in Palos Crater on equatorial Mars. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter recorded this image on March 8, 2010. The target for this HiRISE observation was a suggestion submitted through the camera team's HiWish public-suggestion program. For more information about how to submit target suggestions, see http://uahirise.org/hiwish/.The floor appears bumpy with high-standing layered knobs. Most of the terrain on the floor is weathering into meter-size (yard-size) polygonal blocks. The circular structures in the image, many of which are filled with darker wind-blown material, are eroded impact craters.Palos Crater is breached in the south by the 180-kilometer-long (112-mile-long) Tinto Vallis. Water transported along Tinto Vallis could have could have collected into Palos Crater to form a lake that later drained to the north. Sediments carried by Tinto Vallis would have also been deposited within Palos Crater, so the layered unit we see along the floor today could represent these fluvial sediments.This image covers a swath of ground about 1 kilometer (about two-thirds of a mile) wide. It is a portion of HiRISE observation ESP_016943_1775, which is centered at 2.67 degrees south latitude, 111.13 degrees east longitude. The season on Mars is southern-hemisphere autumn. Other image products from this observation are available at http://hirise.lpl.arizona.edu/ESP_016943_1775.Color images from HiRISE combine information from detectors with three different color filters: red, infrared, and blue-green. Thus they include information from part of the spectrum human eyes cannot see and are not true color as the eye would see. The resulting false color helps to show differences among surface materials. The University of Arizona, Tucson, operates the HiRISE camera, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo.

https://photojournal.jpl.nasa.gov/catalog/PIA21149	/content/Nasa_Mars_Images/PIA21149_modest.jpg	This graphic shows proportions of minerals identified in mudstone exposures at the 'Yellowknife Bay' location where NASA's Curiosity Mars rover first analyzed bedrock, in 2013, and at the 'Murray Buttes' area investigated in 2016.	This graphic shows proportions of minerals identified in mudstone exposures at the "Yellowknife Bay" location where NASA's Curiosity Mars rover first analyzed bedrock, in 2013, and at the "Murray Buttes" area investigated in 2016.Minerals were identified by X-ray diffraction analysis of sample powder from the rocks. The samples were acquired by drilling and delivered to the Chemistry and Mineralogy (CheMin) instrument inside the rover.Two key differences in the Murray Buttes mudstone include hematite rather than magnetite, and far less abundance of crystalline mafic minerals, compared to the Yellowknife Bay mudstone composition. Hematite and magnetite are both iron oxide minerals, with hematite as a more oxidized one. That difference could result from the Murray Buttes mudstone layer experiencing more weathering than the Yellowknife Bay mudstone. More weathering could also account for the lower abundance of crystalline mafics, which are volcanic-origin minerals such as pyroxene and olivine.The Yellowknife Bay site is on the floor of Gale Crater. The Murray Buttes site is on lower Mount Sharp, the layered mound in the center of the crater. A map at PIA21144 shows these locations.Presented at the 2016 AGU Fall Meeting on Dec. 13. in San Francisco, CA.NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington.For more information about Curiosity, visit http://www.nasa.gov/msl and http://mars.jpl.nasa.gov/msl.

https://photojournal.jpl.nasa.gov/catalog/PIA07993	/content/Nasa_Mars_Images/PIA07993_modest.jpg	This mosaic from NASA's Mars Odyssey spacecraft shows a region of martian troughs named Nili Fossae. The olivine-rich exposures appear magenta to purple-blue in this color-coding.	Colors indicate infrared emission signatures in this mosaic of images from NASA's Mars Odyssey orbiter of a region of martian troughs named Nili Fossae. Analysis of this information from Odyssey's Thermal Emission Imaging System suggests that a deposit rich in the mineral olivine is about four times larger than indicated in earlier data from a lower-resolution infrared instrument on NASA's Mars Global Surveyor. The olivine-rich exposures appear magenta to purple-blue in this color-coding. Olivine can turn into other minerals rapidly in the presence of water. This deposit, in a relatively old region of Mars' surface adjacent to one of the planet's largest volcanoes, Syrtis Major, suggests the region may never have seen much water.The mosaic covers most of an area about 380 kilometers (about 240 miles) wide, from 75 degrees to 81 degrees in east longitude and from 18 degrees to 25 degrees in north latitude. North is up. Emission intensities at infrared wavelengths of 12.57 microns, 11.04 microns and 9.35 microns are displayed in red, green and blue, respectively. This mosaic was presented in a report in the June 2005 issue of the journal Geology.

This image was produced by combining the 'Super pan' frames from the IMP camera. Sol 1 began on July 4, 1997.	The "Mini Matterhorn" is a 3/4 meter rock immediately east-southeast of the Mars Pathfinder lander. This image, along with PIA00816 and PIA00818, shows how super resolution techniques can be applied to nearfield targets to help to address questions about the texture of the rocks at the landing site and what it might tell us about their modes of origin. PIA00816 shows a "raw," standard-resolution color frame of the rock. This image and PIA00818 were produced by combining the "Super pan" frames from the IMP camera. The composite color frame consists of 7 frames from the right eye, taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. This panchromatic frame was then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is a division of the California Institute of Technology (Caltech). Photojournal note: Sojourner spent 83 days of a planned seven-day mission exploring the Martian terrain, acquiring images, and taking chemical, atmospheric and other measurements. The final data transmission received from Pathfinder was at 10:23 UTC on September 27, 1997. Although mission managers tried to restore full communications during the following five months, the successful mission was terminated on March 10, 1998.

Morgan Montalvo, an engineer at NASA's Jet Propulsion Laboratory, sets guardrails on the floor below a prototype of the lander being designed for the agency's Mars Sample Return campaign. These guardrails were used to test a scenario where the lander would "stub a toe" against a rock while touching down on Mars.The Sample Retrieval Lander, estimated to weigh as much as 5,016 pounds (2,275 kilograms), would be the heaviest spacecraft ever to land on the Red Planet. To study the physics involved in landing such a massive spacecraft, engineers have been testing a lander prototype that's about one-third the size it would be on Mars.Mars Sample Return will revolutionize our understanding of Mars by bringing scientifically selected samples to Earth for study using the most sophisticated instrumentation around the world. NASA's planned Mars Sample Return (MSR) campaign would fulfill one of the highest priority solar system exploration goals identified by the National Academies of Sciences, Engineering and Medicine in the past three decadal surveys. This strategic partnership with the ESA (European Space Agency) features the first mission to return samples from another planet, including the first launch from the surface of another planet. The samples being collected by NASA's Perseverance rover during its exploration of an ancient river delta are thought to be the best opportunity to reveal the early evolution of Mars, including the potential for ancient life.For more about Mars Sample Return: https://mars.nasa.gov/msr/

Context imageAt the top of today's VIS image is a delta deposit that was created by the flow from the rim channel into the crater. Deltas form when sediments settle out due to a decrease in speed of a river system. Deltas often form where large rivers flow into the ocean, like the Mississippi and Nile deltas. This can also occur where rivers flow into large lakes, such as the Great Salt Lake and Lake St. Clair river deltas. It is believed that the Jezero Crater delta formed this way. The delta in Jezero Crater has been chosen as the location for the Mars 2020 mission.Orbit Number: 77838 Latitude: 18.1853 Longitude: 77.4252 Instrument: VIS Captured: 2019-07-02 11:53Please see the THEMIS Data Citation Note for details on crediting THEMIS images.NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C.

This image was acquired by NASA's Phoenix Mars Lander's Surface Stereo Imager on the 31st Martian day of the mission, or Sol 31 (June 26, 2008), after the May 25, 2008 landing. This image shows the trenches informally called "Snow White 1" (left), "Snow White 2" (right), and within the Snow White 2 trench, the smaller scraping area called "Snow White 3." The Snow White 3 scraped area is about 5 centimeters (2 inches) deep. The dug and scraped areas are within the diggiing site called "Wonderland."The Snow White trenches and scraping prove that scientists can take surface soil samples, subsurface soil samples, and icy samples all from one unit. Scientists want to test samples to determine if some ice in the soil may have been liquid in the past during warmer climate cycles.The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA.

Map Projected Browse ImageClick on image for larger versionLarge craters, like this 50-kilometer diameter one, can uplift material from below and form a mountain-like central peak. Craters of this size on Mars become unstable as they form and collapse due to gravity. Craters with central peaks and terraced rims are referred to as "complex" craters.Geologists study these central peaks because the uplifted bedrock was once deep within the Martian crust. A 3D perspective shows heavily-fractured bedrock exposed within the peak, and also dark-toned and fragmental rocks that formed during the impact process. Sometimes, we observe similar rocks in the crater wall terraces. Some areas of the terrace show dark-toned materials coating and surrounding the white- and green-colored bedrock. This dark-toned rock was the once-molten material that was produced by the tremendous energy generated during the formation of the crater. Similarly, the impact melt material coats and surrounds the higher-standing bedrock of the peak. There are additional exposures of bedrock in the northern wall-terraces of the crater.Previous HiRISE images have focused largely on central structures, but clearly the wall-terraces of these craters may also be informative in our exploration of the Martian subsurface.The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 25.8 centimeters (10.2 inches) per pixel (with 1 x 1 binning); objects on the order of 77 centimeters (30.3 inches) across are resolved.] North is up.The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado.

https://photojournal.jpl.nasa.gov/catalog/PIA26059	/content/Nasa_Mars_Images/PIA26059_modest.jpg	This image from NASA's Mars Odyssey shows part of the floor of Kaiser Crater.	Context imageThe THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows part of the floor of Kaiser Crater. Kaiser Crater is 207 km (129 miles) in diameter and is located in Noachis Terra west of Hellas Planitia. This sand dune field is one of several regions of sand dunes located on the southern part of the crater floor. The image also shows the complex crater floor beneath the dunes. These dunes are composed of basaltic sand that has collected in the bottom of the crater. The topographic depression of the crater forms a sand trap that prevents the sand from escaping. Dune fields are common in the bottoms of craters on Mars and appear as dark splotches that often lean up against the downwind walls of the craters. Dunes are useful for studying both the geology and meteorology of Mars. The sand forms by erosion of larger rocks, but it is unclear when and where this erosion took place on Mars or how such large volumes of sand could be formed. The dunes also indicate the local wind directions by their morphology.The THEMIS VIS camera is capable of capturing color images of the Martian surface using five different color filters. In this mode of operation, the spatial resolution and coverage of the image must be reduced to accommodate the additional data volume produced from using multiple filters. To make a color image, three of the five filter images (each in grayscale) are selected. Each is contrast enhanced and then converted to a red, green, or blue intensity image. These three images are then combined to produce a full color, single image. Because the THEMIS color filters don't span the full range of colors seen by the human eye, a color THEMIS image does not represent true color. Also, because each single-filter image is contrast enhanced before inclusion in the three-color image, the apparent color variation of the scene is exaggerated. Nevertheless, the color variation that does appear is representative of some change in color, however subtle, in the actual scene. Note that the long edges of THEMIS color images typically contain color artifacts that do not represent surface variation.Orbit Number: 91155 Latitude: -46.9827 Longitude: 19.3481 Instrument: VIS Captured: 2022-07-02 23:58Please see the THEMIS Data Citation Note for details on crediting THEMIS images.NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C.

This image shows the patch of soil at the bottom of the shallow depression dubbed "Laguna Hollow" where the Mars Exploration Rover Spirit will soon begin trenching. Scientists are intrigued by the clustering of small pebbles and the crack-like fine lines, which indicate a coherent surface that expands and contracts. A number of processes can cause materials to expand and contract, including cycles of heating and cooling; freezing and thawing; and rising and falling of salty liquids within a substance. This false-color image was created using the blue, green and infrared filters of the rover's panoramic camera. Scientists chose this particular combination of filters to enhance the heterogeneity of the martian soil.

The yardangs are the ridge-like landforms that align approximately north-south.	Map Projected Browse ImageClick on the image for larger versionIn this image, an ancient sinuous meandering river system is surrounded by features called "yardangs." The yardangs are the ridge-like landforms that align approximately north-south. These features were created as the wind scoured and eroded the bedrock.The raised relief of the meandering river suggests inverted topography, likely due to lithification and cementation of the riverbed sediment. The cemented channel deposits were resistant, and thus less susceptible to erosion over time. However, the area surrounding the riverbed suggests that this area was a floodplain of weaker lithology that was subsequently eroded and shaped to the yardangs.The main meandering inverted riverbed within the image has a length of about 13 kilometers. The elevation of the channel at the top of the image is on the order of 113 meters higher than the bottom, based on Mars Orbiter Laser Altimeter (MOLA) data. This elevation difference and the increase in sinuosity of the channel shape in the southerly direction implies that the flow of the ancient river may have been heading south-southwest.This is a stereo pair with ESP_025407_1745.The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo.
