I can't say whether this means they're done at the Kimberley or not. They could still drill one of the other two rock units in this location. On the other hand, they are under a lot of pressure to keep driving toward Mount Sharp. I suppose it depends upon what the team sees in the early CheMin and SAM analyses.

EDIT: JPL has now announced that "The rover team has decided not to drill any other rock target at this waypoint. In coming days, Curiosity will resume driving toward Mount Sharp, the layered mountain at the middle of Mars' Gale Crater. The rover is carrying with it some of the powdered sample material from Windjana that can be delivered for additional internal laboratory analysis during pauses in the drive."

Some of you may be wondering when we are going to get the science results from the Kimberley: what is in the stuff that they drilled out of Windjana? I counsel patience. There are two things that control when we hear about the science from the Curiosity mission: the timing of scientific meetings where they present the results to their peers, and the timing of public release of Curiosity data. In general, the Curiosity science team is forbidden from sharing and discussing scientific data from the mission until after the data are publicly available. Of course, JPEG versions of images are available instantly, but they're not science data; the science data from all instruments are released roughly 4 to 8 months after they're acquired, in batches three times a year. This has caused very awkward conversations between me and mission scientists at science meetings. Because I know what the rover has been doing (because I can see what it has been doing in the released raw images), and the scientists know that I know, they know they can discuss rover actions that are obvious in photos, but they can't discuss science, and there are lots of pauses in conversation and there is much staring off into space as they think about what they're allowed to say.

So far, data have been released through sol 449; Curiosity was at Cooperstown then. Drilling at Windjana happened on sol 621, and the first CheMin and SAM analyses happened on sols 623 and 624. SAM analysis will likely continue for weeks, as Curiosity continues chewing on samples while on the road. Here are the upcoming dates of meetings and data releases. As you can see, the next data release covers up to just before they got to Windjana. So the science team is not allowed to discuss the results from the drilling campaign at the Kimberley until December unless the mission leadership chooses to discuss it earlier. But the good thing about that is that the next data release will cover enough time after Windjana that it should cover all the SAM analyses that will be done on the newly drilled sample. So although we could hear some science results from Windjana earlier, we'll definitely hear about them at the American Geophysical Union meeting.
