Comanche
Comanche About three months after Spirit sent her last communiqué, in June 2010, presumably while the rover was still in hibernation, Richard Morris and MER Science Team colleagues announced that Comanche (the big brown outcrop) is harboring magnesium iron carbonate, and a lot of it. they theorized that it could have been produced by a hydrothermal system. It was a discovery MER PI Steve Squyres called “one of the top five findings of the entire mission.” NASA / JPL-Caltech / Cornell / ASU
