Space Daily has a review of a new book on Europa, Unmasking Europa. The author, a scientist, defends the thin crust view of Europa. If this view is correct (and it's not the consensus view), then life in the oceans of Europa would be more likely. It would also mean that ocean material would be more likely to be brought to the surface, making it easier for future missions to land in areas with access to material from the ocean. The book sells for $18.15 on Amazon in the United States.
This evening I'll post a description of the proposed Io Volcano Observer. Later in the week, I'll post my thoughts on a Titan/Enceladus mission after seeing the presentations on those two worlds at the American Geophysical Union. I'll also post information on the proposed Venus Flagship mission.
In the meantime, be sure to check out Emily Lakdawalla's posts on results presented at the meeting. She does an awesome job of reporting on the the findings that a presented in fast moving meetings.
