MARS GLOBAL SURVEYOR October 30, 2006 Image of the Week

o Light-toned Rock Outcrop in Aureum Chaos (Released 30 October 2006)

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an outcrop of light-toned, layered, sedimentary rock in Aureum Chaos. The darker material, which includes ripples, is composed of windblown sand and granules. This scene is located near 3.8S, 26.2W, and covers an area roughly 7.7 km by 3 km wide. Sunlight illuminates the terrain from the top/upper right. This southern autumn image was acquired on 14 July 2006.

MARS GLOBAL SURVEYOR October 23, 2006, Image of the Week

o A Few Good Barchans (Released 23 October 2006)

38.5S, 347.1W

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows several small, dark sand dunes and a small crater (about 1 kilometre in diameter) within a much larger crater. The floor of the larger crater is rough and has been eroded with time. The floor of the smaller crater contains windblown ripples. The steep faces of the dunes point to the east (top), indicating that the dominant winds blew from the west (bottom). This scene is located near 38.5S, 347.1W, and covers an area approximately 3 km wide. Sunlight illuminates the landscape from the bottom left. This southern autumn image was acquired on 1 July 2006.

MARS GLOBAL SURVEYOR IMAGES October 17, 2006

o Frost-free North Polar Layers in the Good Old Summertime (Released 17 October 2006)

The middle portion of the northern summer season is the ideal time of year to capture relatively dust- and haze-free views of martian north polar terrain. This year, much more of the north polar cap has sublimed away than has been evident in previous northern summers going back to 1999, when Mars Global Surveyor (MGS) began the Mapping Phase of the mission. This MGS Mars Orbiter Camera (MOC) image shows a nearly ice-free view of layers exposed by erosion in the north polar region. The light-toned patches are remnants of water ice frost. The layers are generally considered by the Mars scientific community to be record of past depositions of ice and dust. This picture is located near 82.5N, 118.6W, and covers an area about 3 km by 10 km. Sunlight illuminates the scene from the upper left; the image was acquired on 22 September 2006.

A new image taken by the Mars Global Surveyor spacecraft is now available:

o Summertime View of North Polar Sand Dunes (Released 10 October 2006)

The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a suite of dunes in one of the several north polar dune fields. The bright surfaces adjacent to some of the dunes are patches of frost. These dunes spend much of the autumn, winter, and spring seasons covered with carbon dioxide frost. Only in late spring and in summer are the dark windblown sands fully exposed.

The view covers an area approximately 3 km wide and is illuminated by sunlight from the lower left. The dunes are located near 79.8N, 127.1W, and the picture was acquired on 11 September 2006.
