MARS-NASA-OPPORTUNITY
This image obtained from NASA on September 14, 2012, shows spherules on Mars discovered by the long-lived rover Opportunity which are puzzling researchers. The objects concentrated at an outcrop Opportunity reached last week differ in several ways from iron-rich spherules nicknamed "blueberries" the rover found at its landing site in early 2004 and at many other locations to date. Opportunity is investigating an outcrop called Kirkwood in the Cape York segment of the western rim of Endeavour Crater. The spheres measure as much as one-eighth of an inch (3 millimeters) in diameter. The analysis is still preliminary, but it indicates that these spheres do not have the high iron content of Martian blueberries. = RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / NASA" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS =
