Product Description

Over one year after its launch, robot geologist Opportunity has been spending recent sols on Mars inching its way down the slopes of Endurance crater. Littered with martian blueberries,some flat rocks within the crater also seem to have surprising razorbacks -- narrowslabs sticking up along their edges.Like the blueberries, it's possible that the sharp, narrowfeatures are related to water. They could beformed by minerals deposited by water in cracks, withthe surrounding softer material subsequently eroded away.How narrow are they?The ones pictured here in an enhanced color image from Opportunity's panoramic camera areactually only a few centimeters high and about halfa centimeter wide.Impressive 3Dviews have been constructed by stereo experimenterP. Vantuyne based on the camera's left and right eyeimages of the region.
