Well, the rovers surprised us, and Spirit has now crossed over the 1000-Sol threshold (Opportunity will do the same in three more weeks). In anticipation of that, we had to go back and check all the rover and ground support software to be sure that there would not be any unexpected surprises when the chronometer clicked over. But as of this evening, everything looks just fine and we are all set to trundle on through the next 1000 Sols....

Will the problem crop up at Sol 1024 (i.e., ten bit rollover)?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
