The major science stories from Spirit Options

[elakdawalla]

I really, really, really tried to do my own research this time without relying on all you rover-watchers here for help, but after a couple of weeks of banging my head against a wall I'm coming crawling to you for help. I need to produce (for both our website and a podcast) a simplified, big-picture view of what Spirit has accomplished on Mars over the past five years. I've basically got to summarize five years of the mission in four minutes of speaking. The operational details (the main mileposts on the drive) are very easy to figure out with the help of Tesheiner's maps and the discussions in the route map thread, so I've got that in hand. What I am having trouble with is figuring out the answers to the following science questions:

1. What is the summary story that can be told about the history of the interior of Gusev crater based on Spirit's observations? Geology is fundamentally a science devoted to telling a story about a landscape -- what's the basic story that the Gusev landscape is telling us, as revealed by Spirit?

2. What are the biggest science discoveries -- I'm talking about the top three or five stories -- that Spirit has made?

There's just so much material on Spirit that I'm having an awful time trying to see the forest for all the trees. All the journal articles that I can find are just devoted to one phase of the mission, so I can't figure out which stories are the most significant. I have all of Salley's great articles to go through, but again, they're so detail-rich that it's difficult to figure out what the big picture is; it's like looking at a Seurat painting up close.

Any help or pointers to any place where anybody has already produced some quality science summary would be greatly appreciated.

This isn't really the best thread for this post, but I'm not sure it needs a new thread now.

I am finishing up work on my Mars Atlas vol. 1 (up to Mars Express) and looking ahead at Vol. 2 (MER to present). All the text is done in draft form, so it's illustrations I am looking at. This is an experimental version of a map of early Spirit operations. The whole route would be mapped at larger scale (lower resolution) but sites of interest will be covered like this.

Placenames are a problem. They were for Phoenix as well. Supposedly, they are accessible via the Analyst's Notebook at PDS, but that is filled with inconsistencies, with uncertainty regarding the identity of the named feature, etc. And looking ahead, I see that later in the mission most names are omitted from the Analyst's notebook.

(Mission Ops people! Do us a favor, please keep and make available a proper record of the names you assign!)
