Though Curiosity still lies more than 13,000 feet below the peak of Mount Sharp, in its ten years on Mars it has climbed a considerable distance uphill since leaving the floor of 97-mile-wide Gale Crater, about 2,400 feet. The panorama above, taken today by one of Curiosity’s navigation cameras and rotated and cropped to post here, gives us a good sense of the elevation the rover has gained in that time.
The overview map to the right provides some perspective. Curiosity’s present location is indicated by the blue dot, with the yellow lines indicating the direction of this panorama. Though Curiosity climbed up from that valley on the lower left, none of its route is visible in this picture, as the weaved up from the left and the steepness of the ground hides the lower sections.
The mountain chain in the distance, about 20 to 25 miles away, is the north rim of Gale Crater. Beyond it can faintly be seen other mountains, which form the rim of another smaller crater to the north. The peak of Mount Sharp, about 23 miles to the south and in the opposite direction, forms the wide central peak of Gale Crater, unusual in that it fills much of the crater and rises higher than the crater’s rim, factors which were part of the reason this location was chosen as Curiosity’s landing site.
This picture also allows scientists to get a sense of the dust levels in the Martian atmosphere, which change seasonally depending on dust storm activity. Since it is now summer on Mars, when dust activity is low, the air is relatively clear.
