DAWN arrived in its new lower mapping orbit on August 13th. The DAWN team is preparing to resume science observation tomorrow on the 17th.
From the Current Mission Status page at the DAWN website: QUOTE August 13, 2015 - Dawn Arrives in Third Mapping Orbit
Dawn completed the maneuvering to reach its third mapping orbit and stopped ion-thrusting this afternoon. This was a little ahead of schedule because the spiral descent went so well that some of the allocated thrusting time was not needed. Since July 14, the spacecraft has reduced its orbital altitude from 2,700 miles (4,400 kilometers) to approximately 915 miles (1,470 kilometers). The orbit period has correspondingly decreased from 3.1 days to 19 hours. Dawn is scheduled to begin its new observations on the evening of Aug. 17 (PDT) and continue for more than two months. First, however, the mission control team will measure the actual orbit parameters accurately and transmit them to the spacecraft. |

No problemo-- it's hard to tell who the players are. And on the "current best Ceres map" that area is near where the resolution goes from good to less-than-good and it's hard to tell. It may be some time before the maps get updated with all of the SO imagery.
I have most ("selected") of the SO images with added Feature and Annotation Overlays where I can outline the "slumpages and flowages" and Faculae (bright spots) and a couple of flavors of Lineations and plan to use the Survey images as an Index for the more detailed HAMO and LAMO imagery. --Bill -------------------- |
