PIX4615439: March - Volcanos Ceraunius Tholus and Uranius Tholus - Mars - Volcanos Ceraunius Tholus and Uranius Tholus - Image obtained by the Mars Global Surveyor probe in March 2002. This image shows the volcanoes Ceraunius Tholus (bottom) and Uranius Tholus (top). The presence of impact crateres on these volcanoes indicates that these volcanoes are old. The crater at the top of Ceraunius Tholus is about 25 km in diameter. Acquired in March 2002, this Mars Global Surveyor (MGS) Mars Orbiter Camera wide angle view shows the martian volcanoes, Ceraunius Tholus (lower) and Uranius Tholus (upper). The presence of impact craters on these volcanoes, particularly on Uranius Tholus; indicates that they are quite ancient and are not active today. The light - toned area on the southeastern face (towards lower right) of Ceraunius Tholus is a remnant of a once more extensive deposit of dust from the global dust storm events that occurred in 2001. The crater at the summit of Ceraunius Tholus is about 25 km (15.5 mi) across. Sunlight illuminates the scene from the lower left / Bridgeman Images

PIX4615848: March - Opportunity - Cratere Victoria 09 - 2006 - March: Victoria crater seen from rover Opportunity - Panorama obtained by the rover Opportunity on 28 and 29 September 2006. The Rover Opportunity landed on Mars in the Meridiani Planum region on January 25, 2004. Opportunity reached the Victoria crater on September 27, 2006 after travelling more than 9 km on the surface of Mars. The Victoria crater is about 800 metres wide and its south face on the left is about 6 metres above ground. This image taken by the panoramic camera on the Mars Exploration Rover Opportunity shows the view of Victoria Crater from Duck Bay. Opportunity reached Victoria Crater on Sol 951 (September 27, 2006) after traversing 9.28 kilometers (5.77 miles) since her landing site at Eagle Crater. Victoria Crater is roughly 800 meters (one - half mile) wide - - about five times wider than Endurance Crater, and 40 times as wide as Eagle crater. The south face of the 6 meter (20 foot) tall layered Cape Verde promontory can be seen in the left side of the inner crater wall, about 50 meters (about 165 feet) away from the rover at the time of the imaging. The north face of the 15 meter (50 foot) tall stack of layered rocks called Cabo Frio can be seen on the right side of the inner crater wall. This mosaic was taken on Sols 952 and 953 (September 28 and 29, 2006). There are 30 separate pointings through 6 different filters at each pointing / Bridgeman Images
PIX4615862: March - Opportunity - Panorama - 05/2007 - March: D - Star Panorama by Opportunity (False Color) - Panorama in fake colors obtained by the rover Opportunity on 1st May 2007. The Rover Opportunity landed on Mars in the Meridiani Planum region on January 25, 2004. Opportunity reached the Victoria crater (in the background, at the top of the picture) on September 27, 2006 after having travelled more than 9 km on the surface of Mars. On April 29, 2007, the rover tested a new navigation software to optimize its driving. The traces left on Martian soil are visible to the left of the image. The rocks towards the center of the image are 7 to 10 cm high. This view from Opportunity shows the tracks left by a drive executed with more onboard autonomy than has been used on any other drive by a Mars rover. Opportunity made the curving, 15.8 - meter (52 - foot) drive during its 1,160th Martian day, or sol (April 29, 2007). It was testing a navigational capability called “Field D - star,””” which enables the rover to plan optimal long - range drives around any obstacles in order to travel the most direct safe route to the drive's designated destination. Opportunity and its twin, Spirit, did not have this capability until the third year after their January 2004 landings on Mars. Earlier, they could recognize hazards when they approached them closely, then back away and try another angle, but could not always find a safe route away from hazards. Field D - Star and several other upgrades were part of new onboard software uploaded from Earth in 2006. The Sol 1,160 drive by Opportunity was a Martian field test of Field D - Star and also used several other features of autonomy, including visual odometry to track the rover's actual position after each segment of the drive, avoidance of designated keep - out zones, and combining information from two sets of stereo images to consider a wide swath of terrain in analyzing the route. Two days later, on Sol 1,162, (May 1, 2007), Opp / Bridgeman Images
