On Tuesday (two days from now, for visitors from the future), the first optical navigation image will be taken... hopefully we'll have it in our hands soon after that. So it's time for a new topic. Over the next few months we'll have progressively closer images and full orbit characterization sequences, no doubt including multispectral image sets.
A new world... This is a bit of reprocessing I have been doing with the Hubble images from a few years ago. Phil -------------------- ... because the Solar System ain't gonna map itself.

It sounds pretty settled. Leaving Dawn in a stable orbit around Ceres seems like a nice end to the mission. Someday perhaps we can look forward to a subsequent probe coming along and snapping a picture of it -- which would be really cool.

In one of the most recent Dawn journals describing the moment of capture they used the term "and they will be together forevermore" or something along those lines so yes, it sounds pretty settled. |

it sounds pretty settled. very much so. Our final orbit is also determined, though I would not mind getting even lower. But as we will be covering the majority of the surface in our final orbit altitude at ~35 meter resolution I can't and won't complain! (That is almost three times as good as our effective global resolution of approximately 100 meters over most of Enceladus, our best mapped icy world at present.) -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX

If only for a spare hole in the filter wheel that a parfocal 3x teleconverter could have been slipped into. ;-) But I suppose it would have been beyond budget and requirements.
