| Title |
Marte Vallis Textures |
| Original Caption Released with Image |
20 March 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows platy flow surfaces in the Marte Vallis region of Mars. The origin of the flows is not well-understood, but as some Mars scientists have suggested, the flows may be the product of low viscosity (very fluid), high temperature volcanic eruptions, or perhaps they are the remains of large-scale mud flows. In either case, the materials are solid and hold a record of small meteor impact craters, thus indicating that they are not composed of ice, as still others have speculated. "Location near": 6.7°N, 182.0°W "Image width": ~3 km (~1.9 mi) "Illumination from": lower left "Season": Northern Winter |

| Title |
Northern Impact |
| Original Caption Released with Image |
19 March 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a partially-buried crater in the north polar region of Mars. The circular feature is surrounded and partly overlain by some of the many, many sand dunes in the area. The steepest slopes on each dune -- their slip faces -- face toward the southeast (lower right), indicating that the dominant winds responsible for sand transport in this region come from the northwest (upper left). In summer, the dunes in this scene would be darker than their surroundings, but in this northern springtime image, the dunes and everything else in the area are covered by carbon dioxide frost. The frost is left over from the winter which ended in January 2006. "Location near": 76.0°N, 82.2°W "Image width": ~3 km (~1.9 mi) "Illumination from": lower left "Season": Northern Spring |

The picture on the left is taken from the MOC daily global map acquired at 7.5 km (~4.7 mi) per pixel on 28 January 2006, about a week after the start of southern autumn. The picture on the right was taken at the same time, but at a higher resolution of 489 m (1604 ft) per pixel. Both pictures are composites of MOC red and blue wide angle images, and both are oriented such that north is up and east is to the right. Arsia Mons and the other large Tharsis volcanoes commonly develop afternoon orographic (i.e., topographically-controlled) water ice clouds at this time of year. The equatorial Tharsis volcano, Pavonis Mons, is also under a deck of water ice clouds, it is located toward the upper right corner of the left, lower-resolution image. Sunlight glints off the dusty surface and the clouds and aerosols in the atmosphere, producing the bright diagonal streak located just southeast (lower right) of Arsia Mons. A water ice haze is seen on the left side of the lower-resolution image. The dark oval to the northeast of Arsia Mons, as noted above, is the shadow of Phobos.

11 March 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows some typical relations between impact craters and light-toned, layered rock on Mars. The larger circular feature at the north (top) end of the image marks the location of a filled, buried crater on intermountain terrain north of Hellas Planitia. The larger crater at the southeast (lower right) corner formed by meteor impact into the layered material in which the buried crater is encased. The layered rock, in this case, has a light tone similar to the sedimentary rocks being explored by the Mars Exploration Rover, Opportunity, thousands of kilometers away in Sinus Meridiani. "Location near": 24.9°S, 299.3°W "Image width": ~3 km (~1.9 mi) "Illumination from": upper left "Season": Southern Summer |

12 March 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a mid-summer view of layered terrain in the south polar region of Mars. The general hypothesis that has been around since the Mariner missions to Mars in the late 1960s and early 1970s is that the layered material in the polar regions is composed of some combination of dust and ice in unknown proportions. Alternatively, the layers might be ancient sedimentary rock, perhaps protected from erosion by millennia of seasonal ice caps covering the region for, roughly, half a Mars year.

Mars at Ls 25°: Acidalia/Mare Erythraeum |
| Original Caption Released with Image |
14 March 2006 This picture is a composite of Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) daily global images acquired at Ls 25° during a previous Mars year. This month, Mars looks similar, as Ls 25° occurs in mid-March 2006. The picture shows the Acidalia/Mare Erythraeum face of Mars. Over the course of the month, additional faces of Mars as it appears at this time of year are being posted for MOC Picture of the Day. Ls, solar longitude, is a measure of the time of year on Mars. Mars travels 360° around the Sun in 1 Mars year. The year begins at Ls 0°, the start of northern spring and southern autumn. "Season": Northern Spring/Southern Autumn |

South Polar Autumn |
| Original Caption Released with Image |
18 March 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of the south polar residual cap. The darkened edges of the pits and mesas are evidence of the removal - by sublimation -- of frozen carbon dioxide during the recent martian summer. Summer ended and autumn began the day this image was acquired in January 2006. "Location near": 86.8°S, 90.5°W "Image width": ~3 km (~1.9 mi) "Illumination from": upper left "Season": Southern Summer/Autumn |

Aeolis Yardangs |
| Original Caption Released with Image |
12 January 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a group of tapered ridges, known as yardangs, which formed by wind erosion of a relatively easily-eroded material, most likely sedimentary rock or volcanic ash deposits containing some fraction of sand-sized grains. "Location near": 6.1°S, 210.8°W "Image width": ~2 km (~1.2 mi) "Illumination from": lower left "Season": Southern Summer |

Becquerel's Layers |
| Original Caption Released with Image |
14 January 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned, layered, sedimentary rock outcrops in Becquerel Crater in the western Arabia Terra region. The crater may once have hosted a lake, into which these sediments were deposited. Although the fine, detailed layering in Becquerel was not known until the MGS MOC first began to image these materials in 1999, the presence of a grossly-layered, light-toned feature was known from Viking orbiter images and was speculated from those data to possibly represent evidence for the presence of a former lake.

North Polar Layers |
| Original Caption Released with Image |
13 January 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a slope on which layered materials are exposed by erosion in the north polar region of Mars. Wind streaks are also evident in this summertime scene. The layers that make up the material beneath the ice of the north polar residual cap are typically considered to be a mixture of some amount of dust and ice, but the proportions of these constituents are not known.
