Mars Up Close

Ever since Spirit and Opportunity began relaying images from Mars in January 2004, scientists following them have employed an unusual lexicon, referring to martian "blueberries," "popcorn," and "deep-fried," "batter-coated" blobs. The intrepid Mars Exploration Rovers are discovering a landscape never seen before as well as offering new perspectives on a central question: Did liquid water ever flow on Mars? In this narrated tour, allow Steve Squyres, the mission's principal science investigator, to guide you through a handful of each rover's most stunning finds.
