The orientation of the dunes -- with the steep faces toward the south bottom -- suggests that winds generally blew from north to south at the time the dunes were formed. This figure shows a cross-section of the planet Mars revealing an inner, high density core buried deep within the interior. Dipole magnetic field lines are drawn in blue, showing the global scale magnetic field that one associates with dynamo generation in the core.

Mars must have one day had such a field, but today it is not evident. Perhaps the energy source that powered the early dynamo has shut down. The differentiation of the planet interior - heavy elements like iron sinking towards the Daedalia Planum is a vast region covered with the extremely large lava flows of southern Tharsis. The trough in the lower third of the image is a graben formed by extension and faulting of the martian crust.

This image is located near Sunlight illuminates the scene The origin of the flow material has been a subject of debate among Mars scientists; it may have been very fluid lava or mud flows. In either case the material was buried for some time. Windblown features, both the large, dark-toned sand dunes and smaller, light-toned ripples, obscure and perhaps, protect portions of the crater floor from further modification by erosional processes.

This image combining a topographic map viewed obliquely color portion of image with a radargram of the subsurface monochrome portion shows features of mysterious Martian deposits named the Medusae Fossae Formation. The westward-looking view includes the divide between Martian highlands on the south and lowlands on the north, spanning a range from about 12 degrees south latitude left edge of image to 5 degrees north latitude right edge of image. The deposits of the Medusae Fossae The bulk of the ice in the south polar residual cap is frozen carbon dioxide.

Centered at 70S, W, this view--taken in early spring when sunlight has just begun to shine on the region for the first time in many months--includes a bright region diagonal from center-left to lower right known for nearly two centuries as the "Mountains of Mitchel. This month, Mars looks similar, as Ls 12 occurred in mid-February 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 A vast sea of sand dunes nearly surrounds the north polar cap. These landforms are located near Light-toned features in the image are exposures of the substrate that underlies the dune field. The image covers an area about 3 km 1. The third stage is a solid-propellant Thiokol Star 48B booster, the same final stage used in the launch of Mars Global Surveyor.

Targeted for launch on Dec. Source: Cold and cloudy mornings; cool, hazy afternoons. High winds aloft and weather fronts moving slowly to the east. It is winter in the Martian northern hemisphere. One of the many reasons to study Mars is that, at times, its weather is very "Earth-like. Clouds and fogs are also observed in low-lying areas farther to the south, in some lowlands they are as far Pathfinder, a low-cost Discovery mission, is the first of a new fleet of spacecraft that are planned to explore Mars over thenext ten years.

Mars Global Surveyor, already en route, arrives at Mars on September 11 to begin a two year orbital reconnaissance of the planet's composition, topography, and climate.

Additional orbiters and landers will follow every 26 months. The Jet Propulsion Laboratory, Pasadena, The basin might once have been the site of a large lake--that is, if the sedimentary rocks exposed on its northwestern floor were deposited in water.

The image is located near Released 12 June The Science One of the many branches of the Mangala Vallis channel system is seen in this image.

The water that likely carved the channels emerged from a huge graben or fracture almost km to the south. A bright scarp marks the transition between the two terrain types and demonstrates that in this location the highlands terrain is being eroded back.

Note how The Surveyor spacecraft upper is already mated to its solid propellant upper stage booster lower , which is actually the third stage of the Delta II expendable launch vehicle that will propel the spacecraft on its interplanetary journey to the Red Planet. Once at Launch Pad 17A on Cape A portion of the rim and interior of the large impact crater Schiaparelli is seen at high resolution in this image acquired October 18, by the Mars Global Surveyor Orbiter Camera MOC.

The area covered is very small The subdued relief and bright surface are attributed to blanketing by dust; many small craters have been completely filled in, and only the most recent and very small craters The two pictures above show the remains of layered material inside craters in southwestern Utopia Planitia see inset for detailed view.

These remnant layers indicate that the craters--and perhaps the plains that surround them--were once buried beneath a deposit that has since been eroded away.

This theme of layered outcrops The bright, relatively homogeneous-appearing material extending from top north to bottom south is mainly composed of solid carbon dioxide. During the martian summer months, sublimation, the direct conversion of a solid to a gas, causes the scarps that delineate the edges of the bright material to retreat by approximately 3 meters around 10 feet before Wind streaks formed in the lee -- i. Near the bottom south of the image, three light-toned slope streaks, created by dry mass movements of dust, extend down The sounding radar collected the data presented here during orbit of the mission, on Nov.

The horizontal scale in the radargram is distance along the ground track. It can be referenced to the ground track map shown in the lower right. The radar traversed from The lower image shows the position of the ground track on a topographic map of the area based on Mars Orbiter Laser Altimeter data. The images are kilometers miles wide. Unique among the MOC images is a suite of pictures from northwestern Hellas Planitia, such as the example shown here.

The seeming familiarity of many MOC images, such as those showing earth-like sand dunes or stream-like gullies might give the impression that it is pretty easy to understand what MOC images are telling us about the geology of Mars. Indeed, much of what has been found by MOC Imagine the MOC imaging team's surprise on the morning of April 27, , as the latest images came in from the "Red Planet. Who's been driving around on Mars?

The MOC image in question , seen here at full resolution of The dike is the narrow, discontinuous ridge that cuts diagonally from the northwest upper left toward the southeast lower right across the scene. The magma Much of the south polar region of Mars is covered by a thick unit of layered material. For decades, the layers have been assumed to consist of a mixture of dust and ice, but it is equally possible that the materials are sedimentary rocks.

The scalability and precision of the analyzer are achieved by using an incremental framework in which a pointer analysis and a numerical analysis of array indices mutually refine each other. CGS has been designed so that it can distribute the analysis over several processors in a cluster of machines. To the best of our knowledge this is the first distributed implementation of static analysis algorithms.

Throughout the paper we will discuss the scalability setbacks that we encountered during the construction of the tool and their impact on the initial design decisions. Document ID.
