Dantu crater: furrowed floor

Dantu crater: furrowed floor
Dantu crater: furrowed floor On Dec. 21, in its lowest orbit at about 240 miles (385 kilometers), Dawn flew over Dantu crater and obtained pictures with four times the clarity of the third mapping orbit, where we saw the entire crater. (Dantu is a timekeeper god who initiates the cycle of planting rites among the Ga people of the Accra Plains of southeastern Ghana.) The bright material here is at the 4:00 position, half way from the center to the rim, in the picture shown in November. The network of fractures may have formed when the ground cooled after being heated by the crater-forming impact, or perhaps later when other geological processes caused the crater floor to be uplifted. The crater is about 78 miles (126 kilometers) in diameter. The next picture below shows detail of another part of Dantu. The animation above includes Dantu (as seen from farther away). Full image and caption. NASA / JPL-Caltech / UCLA / MPS / DLR / IDA
