As always, the flurry of snaps seems to have given NASA more food for thought.
The fresh views shows the Kupalo Crater having a bright material on its rim and walls which, scientists are yet to confirm as salts.
In December, a study published in Nature described how the bright spots on one of Ceres' other craters, Occator, could be explained by salt formation.
"When we set sail for Ceres upon completing our Vesta exploration, we expected to be surprised by what we found on our next stop. Ceres did not disappoint," said Chris Russell, principal investigator for the Dawn mission.
"Everywhere we look in these new low- altitude observations, we see amazing landforms that speak to the unique character of this most amazing world."
