I’ve been so taken with HiRISE lately that I haven’t written much about the Mars rovers Spirit and Opportunity. They’ve been traversing Mars for almost six years now, taking tons of images and great in situ data. And now I feel remiss, because Spirit has stumbled on something very cool. These images were taken on Sol 1858, just a few days ago (a Sol is a day on Mars, about a half hour longer than an Earth day). Spirit has been tooling around a high plateau called Home Plate, because it’s shaped like, well, a home plate in baseball. There’s evidence that water flowed in this area a long time ago, and as I looked over the images it was pretty obvious.
