When Dawn was farther away, the crater appeared to con- tain a single bright spot. But when Dawn JPL Director Charles Elachi delivers his final State of the Lab address Feb. 23. reached its current orbit, the feature was revealed to be two spots. “Now, this complex distribution of re- flective material reveals a 57-mile-diam- eter crater with a complex and intriguing pattern of reflective material inside,” said Rayman. Overall, the body’s defining feature, the bright spots, have been observed at multiple sites across Ceres—more than 130 locations so far by the team, said Rayman. Oxo Crater, about six miles in diam- eter, is notable for its mysterious bright materials inside and out. Rayman said a spectrometer on Dawn observed water on its surface, likely in the form of ice or hydrated minerals. It’s the only area where water was observed. “Following the impact that excavated Occator Crater, scientists believe under- Occator Crater, measuring 57 miles across and 2.5 miles deep, contains the brightest area on Ceres.
