New Mission Update by Steve Squyres at the Athena site. Summary: Similar to the other rocks around here, Comanche is relatively unaltered and has lots of olivine, but it otherwise appears to have a different composition from anything so far, so it may be yet another new Gusev rock type. Next Spirit target is El Dorado; expect lots of driving. Oppy, on the other hand, won't be going anywhere for awhile as they are still figuring out how to safely stow the arm. "64KC" now probably the best-imaged site on the planet. :)
