Yeah, too early. Heck, they're already working out how to position the rovers to make it through the winter. Can you imagine those two little guys continuing to roll blithely around Mars for another year?

The story of MER is going to take multiple volumes, though. Just the images alone span multiple DVDs already. And that's just the images. The fact that the digital data is so widely available as the mission is proceeding is one of the qualitative differences--milestones--of MER. With the right interpretive front-end, we can appreciate and vicarously experience the mission. I think we've entered a new age which devalues printed volumes like Apogee's (as much as I've enjoyed them, especially the volumes about the "Golden Age" missions of the 60s). The operative word is "realtime" in the 21st Century.
