Here’s another report on the planetary sciences/NASA dispute this week over funding and grant scheduling.
From this report it appears that the complaints by the planetary science community might have been a bit overstated. It doesn’t appear that NASA is cutting the planetary sciences grant program in any significant way.
I suspect that the reason the planetary scientists are so touchy is because they do not trust the Obama administration, based on its previous efforts to eliminate the planetary program entirely. (It is also possible that they are right.)
