Weather Movie, Mars South Polar Region, March-April 2009 (Close)
- April 15, 2009
This movie shows the southern high-latitudes region of Mars from March 19 through April 14, 2009, a period when regional dust storms occurred along the retreating edge of carbon-dioxide frost in the seasonal south polar cap. Compared with a full-hemisphere view, this view shows more details of where the dust clouds formed and how they moved around the planet.
The movie combines hundreds of images from the Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter.
In viewing the movie, it helps to understand some of the artifacts produced by the nature of MARCI images when seen in animation. MARCI acquires images in swaths from pole-to-pole during the dayside portion of each orbit. The camera can cover the entire planet in just over 12 orbits, and takes about 1 day to accumulate this coverage. The indiviual swaths are assembled into a mosaic, and that mosaic is shown here wrapped onto a sphere. The blurry portions of the mosaic, seen to be "pinwheeling" around the planet in the movie, are the portions of adjacent images viewing obliquely through the hazy atmosphsere. Portions with sharper-looking details are the central part of an image, viewing more directly downward through less atmosphere than the obliquely viewed portions. MARCI has a 180-degree field of view, and Mars fills about 78 percent of that field of view when the camera is pointed down at the planet. However, the Mars Reconnaissance Orbiter often is pointed to one side or the other off its orbital track in order to acquire targeted observations by the higher-resolution imaging systems on the spacecraft. When such rolls exceed about 20 degrees, gaps occur in the mosaic of MARCI swaths. Also, dark gaps appear when data are missing, either because of irrecoverable data drops, or because not all the data have yet been transmitted from the spacecraft.
It isn't easy to see the actual dust motion in the atmosphere in these images, owing to the apparent motion of these artifacts. However, by concentrating on specific surface features (craters, prominent ice deposits, etc.) and looking for the brownish clouds of dust, it is possible to see where the storms start and how they move around the planet.
In additon to tracking the storms, it is also interesting to watch how the seasonal cap shrinks from the beginning to the end of the animation. This shrinkage results from subliming of the carbon-dioxide frost from the surface as the frost absorbs southern hemisphere mid-spring sunlight. The temperature contrast between the warm sunlit ground just north of the cap's edge and the cold carbon-dioxide frost generates strong winds, enhanced by the excess carbon dioxide subliming off the cap. These winds create the conditions that lead to the dust storms.

Mars Rovers Battle Severe Dust Storm
- July 20, 2007
Whopper dust storms on Mars are whipping up potential problems for the twin Mars rovers, Opportunity and Spirit. Opportunity in particular is getting less power from the sun because it's blocked by a dusty haze. To conserve Opportunity's power supply, engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, have told the rover to conduct only essential operations. Once the storm subsides, the plan is to have Opportunity descend into Victoria Crater, which could be a site of intriguing science discoveries.
Huge dust storms whip around Mars every 5 to 6 years. Scientists hope the rovers will weather this latest storm, and in fact, that they will learn a lot about Martian dust storms from observations made by the rovers, by NASA's orbiting Mars Odyssey and Mars Reconnaissance Orbiter, and by the European Mars Express spacecraft.

Opportunity Poised to Enter Victoria Crater
- June 28, 2007
It's been almost a two-year journey for Opportunity to travel to and along the half-mile-wide Victoria Crater. Now after months of looking for just the right spot, it peers over the edge of "Duck Bay," ready to descend soon into perhaps its greatest adventure yet.
In this video, mission project manager John Callas shares the challenges around the decision to send the rover inside and the risks and discoveries that may lie down below.

Flying Over Opportunity's Work Site
- March 13, 2007
Images of "Victoria Crater" in Mars' Meridiani Planum region, taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter, provided detailed, three-dimensional information that was used to create this animation of a hypothetical flyover. NASA's Mars Exploration Rover Opportunity reached the edge of this crater in September 2006 and began exploring its rim clockwise.
Victoria is about 800 meters (one-half mile) in diameter. This animated flyover approaches the crater from the south, and then moves counterclockwise around part of the rim. An enhanced glimpse of Opportunity appears at a location where the rover was seen by the orbiter.

Animated Elevation Model of 'Victoria Crater' - September 11, 2006
After driving more than 9 kilometers (5.6 miles) from the site where it landed in January 2004, NASA's Mars Exploration Rover Opportunity approached "Victoria Crater" in September 2006. The crater is about 750 meters (half a mile) across. That is about six times wider than "Endurance Crater," which Opportunity spent six months examining in 2004, and about 35 times wider than "Eagle Crater," where Opportunity first landed. The walls of Victoria hold the scientific allure of much taller stacks of geological layers -- providing the record of a longer span of the area's environmental history -- than Opportunity has been able to inspect on the Meridiani plains or at smaller craters.
This animation created by the U.S. Geological Survey uses a digital elevation model generated from computer analysis of three images taken by the Mars Orbiter Camera aboard NASA's Mars Global Surveyor orbiter. The vertical dimension is not exaggerated relative to the horizonal dimensions. The crater is about 70 meters (230 feet) deep.
The images used for providing the stereo information to calculate relative elevation were taken on Feb. 1, 2004, Feb. 15, 2004 and April 16, 2005. The animation begins and ends with the view looking from the northwest toward the southeast. Opportunity is approaching Victoria from the northwest.

Erebus Rim - January 23, 2006
This is the Opportunity panoramic camera's "Erebus Rim" panorama, acquired on sols 652 to 663 (Nov. 23 to Dec. 5, 2005 ), as NASA's Mars Exploration Rover Opportunity was exploring sand dunes and outcrop rocks in Meridiani Planum. The panorama originally consisted of 635 separate images in 4 different Pancam filters, and covers 360 degrees of terrain around the rover and the full rover deck. Since the time that this panorama was acquired, and while engineers have been diagnosing and testing Opportunity's robotic arm, the panorama has been expanded to include more than 1,300 images of this terrain through all of the Pancam multispectral filters. It is the largest panorama acquired by either rover during the mission.
The panorama shown here is an approximate true-color rendering using Pancam's 750 nanometer, 530 nanometer and 430 nanometer filters. It is presented here as a cylindrical projection. Image-to-image seams have been eliminated from the sky portion of the mosaic to better simulate the vista a person standing on Mars would see.
This panorama provides the team's highest resolution view yet of the finely-layered outcrop rocks, wind ripples, and small cobbles and grains along the rim of the wide but shallow "Erebus" crater. Once the arm diagnostics and testing are completed, the team hopes to explore other layered outcrop rocks at Erebus and then eventually continue southward toward the large crater known as "Victoria."

Opportunity Leaving Martian Sand Trap - June 07, 2005
This video shows the Mars rover Opportunity maneuvering out of
a martian sand dune between May 11 and June 3. Engineers at NASA's Jet
Propulsion Laboratory worked for nearly five weeks to get Opportunity free.
The long-distance roadside assistance was a painstaking operation to free
the six wheels of the rover which were stuck up to their rims in the soft
sand of the small sand dune. The rover exited the sand dune in the same
direction it drove into it on April 26th.
