Congress had said that they were going to "allow some flexibility" where it was needed, giving us a little hope, and in fact, NSF and NIST both got small increases over the '06 numbers ($335M and $50M, respectively), but unfortunatly, NASA got nothing.
Senator Mikulski said in her press release that it was unfortunate, but it was the best they could do:
“While I would have liked to have increased funding for NASA, there was simply not enough extra funding available for us to do so. Within the limits of NASA’s FY 06 operating plan, we added an extra $460 million to exploration while protecting other critical NASA programs in science and aeronautics. With only seven months left in this fiscal year, I believe NASA will be able to manage their programs in exploration with minimal impact to the overall schedule.
It's going to be a tough year for NASA, and frankly, the '08 budget is not looking that much better.
