DAWN - image of the day - November 2015
30.11.2015 - Dawn HAMO image 66 (PIA20129)
This image from NASA's Dawn spacecraft shows the dramatic-looking crater named Haulani on Ceres. This relatively young crater was named for a Hawaiian plant goddess, and measures 19 miles (31 kilometers) in diameter. The crater features a central ridge and streaks of bright material on its walls. Ejected material from the crater's formation blankets the surrounding area, muting the appearance of older impact features.
24.11.2015 - Dawn HAMO image 65 (PIA20128)
The terraced rim of the large crater named Urvara can be seen at the upper left in this view from Ceres. Urvara is 106 miles (170 kilometers) wide.
23.11.2015 - Dawn HAMO image 64 (PIA20127)
This view shows cratered terrain in the northern hemisphere of Ceres. Ikapati crater is partially cut off at the top of the scene. It appears to have flat plains in its interior that were filled by flows, and it is surrounded by smooth material and ejecta from the crater’s interior. On the crater floor are clusters of small pits, some surrounded by bright material.
20.11.2015 - First complete look at Ceres’ poles (PIA20126)
Researchers from NASA's Dawn mission have composed the first comprehensive views of the north (left) and south pole regions (right) of dwarf planet Ceres, using images obtained by the Dawn spacecraft. The images were taken between Aug. 17 and Oct. 23, 2015, from an altitude of 915 miles (1,470 kilometers).
19.11.2015 - Dawn HAMO image 63 (PIA20125)
This image of Ceres from NASA's Dawn spacecraft shows hummocky terrain -- a surface covered in low, rounded hills -- with numerous impact craters of varying sizes. The two biggest craters display central peaks and many places where masses of material have collapsed and slid downward along their walls and floors -- a phenomenon geologists call "mass wasting".
18.11.2015 - Dawn HAMO image 62 (PIA20124)
This view of Ceres from NASA's Dawn spacecraft shows a fresh impact crater with a flat floor. The crater is surrounded by smooth, flow-like ejecta that covers adjacent older impact craters. The crater is about 16 miles (26 kilometers) in diameter.
17.11.2015 - Dawn HAMO image 61 (PIA20123)
This image, taken by NASA's Dawn spacecraft, displays a linear structure trending from northeast to southwest (lower left to upper right). The graben -- what geologists call a linear feature where terrain has dropped -- might be interpreted as a chain of collapsed pits or secondary craters. The crater at center right displays terraced walls, a common feature among the impact sites of Ceres.
16.11.2015 - Dawn HAMO image 60 (PIA20122)
Dantu crater on Ceres, seen here at left, reveals structures hinting at tectonic processes that formed the dwarf planet's surface. Linear structures are spread over the crater floor. Outside the crater's rim, the occurrence of linear structures continues the in form of scarps (linear, cliff-like slopes) and ridges. Dantu's diameter is 78 miles (125 kilometers).
13.11.2015 - Dawn HAMO image 59 (PIA20121)
This image of Ceres, taken by NASA's Dawn spacecraft, shows a giant, ancient impact crater with smaller craters in its interior. The large crater shows partial terracing on its southeast rim, whereas the north part is almost fully degraded. Terraces -- generally level areas separated from lower areas by steep slopes -- are common features in large impact craters. The crater's floor is partly covered by smooth material.
12.11.2015 - Dawn HAMO image 58 (PIA20120)
This image of Ceres, taken by NASA's Dawn spacecraft, shows three prominent craters located to the northeast of a terrace (the terrace feature being located at left in this image). The lower two craters, which are larger, have polygonal rims. The steep crater walls, distinct rim and visible ejecta of the upper smaller crater, called Oxo, hint at a fresh impact. Oxo is about 6 miles (9 kilometers) in diameter. Another interesting feature in this view is a short, linear slump, where a mass of material has dropped below the surface, to the east (or right in this view) of Oxo.
11.11.2015 - Dawn HAMO image 57 (PIA20000)
This image of Ceres, taken by NASA's Dawn spacecraft, demonstrates how the relative ages of impact craters can be revealed by their positions relative to each other. In many cases, as with the craters at the center of this view, younger craters are seen to be "superposed" on -- meaning located on top of -- older craters below.
10.11.2015 - Dawn HAMO image 56 (PIA19999)
This image of Ceres, taken by NASA's Dawn spacecraft, shows a 23-mile-wide (37 kilometer-wide) crater called Tupo, which features a curved central peak complex and terraces. The rim of the degraded crater Darzamat (58 miles, 94 kilometers wide) is visible on the lower left border of the image.
09.11.2015 - Dawn HAMO image 55 (PIA19998)
This image of Ceres, taken by NASA's Dawn spacecraft, shows the 49-mile-wide (79-kilometer-wide) crater Nawish, which features a central pit. Numerous linear crater chains dominate the image, which is centered at approximately 20 degrees north latitude, 198 degrees east longitude.
06.11.2015 - Dawn HAMO image 54 (PIA19997)
This image of Ceres, taken by NASA's Dawn spacecraft, shows a densely cratered region centered at 48 degrees north latitude, 286 degrees east longitude. The craters in the image are characterized by different degrees of freshness, reflecting different ages. The sharply defined crater to right of center is named Takel, after the Malaysian goddess in charge of the tuber harvest. Takel has a diameter of 13 miles (21 kilometers) and features a narrow tongue-like deposit extending outward from its lower rim.
05.11.2015 - Dawn HAMO image 53 (PIA19995)
This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers) around mid-latitudes. The image was taken on Sept. 28, 2015, and has a resolution of 450 feet (140 meters) per pixel.
04.11.2015 - Dawn HAMO image 52 (PIA19994)
This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres at mid-latitudes from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 29, 2015, and has a resolution of 450 feet (140 meters) per pixel.
03.11.2015 - Dawn HAMO image 51 (PIA19993)
This image, taken by NASA's Dawn spacecraft, shows a portion of the northern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 25, 2015, and has a resolution of 450 feet (140 meters) per pixel.
02.11.2015 - Dawn HAMO image 50 (PIA19992)
This image, taken by NASA's Dawn spacecraft, shows a portion of the southern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 28, 2015, and has a resolution of 450 feet (140 meters) per pixel.
