According to Space.com, the final selection has been made for the next DISCOVERY mission.
It will be the GRAIL lunar gravity mapping mission. Space.com article Edit: Just noticed that Norm Hartnett posted an official link earlier on the KAGUYA topic: NASA |

Yes, I believe GRAIL needs its own thread.
On to business. Noticed this article a few days back. Thought I'd give someone else a chance to post it first. But here it is. Lockheed Martin |

A major issue is that far side gravity has always been filled in with interpolation from near side data and the regions of the far side that past spacecraft passed over before occultation. Since a spacecraft can't be tracked from earth over much of the far side, there has been a big hole in most coverage. This is one of those missions that, while not flashy, will do some much needed science, though it will also have cameras for PR (kind of reminds me of Juno in that regard).
