This view of an area about 140 kilometers (about 90 miles) wide in the Meridiani Planum region of Mars shows the region around NASA's Mars Exploration Rover Opportunity. Opportunity, in the seventh year of its exploration of Mars, is in the upper central portion of the image, on multi-year trek from Victoria crater toward the much larger Endeavour crater. In April 2010, Opportunity captured views of the rims of Endeavour crater and the more distant Iazu crater on the horizon to southeast from the rover. (See PIA13081 and PIA13080.) The rover's position relative to those craters is indicated here.
This view is a mosaic of daytime infrared images taken by the Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey orbiter.
Below is an annotated version of the above mosaic:
