This thread will cover all final phases of the Dawn mission, the end of which is not certain at this point.
XMO3 was suppose to be the final orbit, but now plans have changed and it will move into a new higher altitude and higher phase orbit soon. This will be XMO4. An interesting monthly journal for January details the plan: Dawn Journal 31 January 2017 |

Perihelion is next April, and it does seem as if most water vapor detections by remote sensors have happened around then.
I concur with Ted. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Perihelion is next April, and it does seem as if most water vapor detections by remote sensors have happened around then. "Ceres' Temporary Atmosphere Linked to Solar Activity ... Villarreal and colleagues showed that past detections of the transient atmosphere coincided with higher concentrations of energetic protons from the sun. Non-detections coincided with lower concentrations of these particles. What's more, the best detections of Ceres' atmosphere did not occur at its closest approach to the sun. This suggests that solar activity, rather than Ceres' proximity to the sun, is a more important factor in generating an exosphere." |
