NASA Watch reports that there will be an update on the Mars Science Lab tomorrow, Thursday. It reports that the speculation is that the mission will be slipped.

If the mission slips with a budget hit of ~$300M, that will be a severe blow to NASA's science portfolio unless Congress provides more money in the 2009 budget. This would be the worst case scenario that Alan Stern has been worrying about.
My fingers are crossed, but a slip is better than flying a mission that can't be ready.
