This is a mosaic assembled from some of the images taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity during the rover's 590th sol (Sept. 21, 2005). The view is toward the south and includes rock exposures north of "Erebus Crater," with the crater in the background. The rover will investigate the exposed rocks in the foreground and will take additional panoramic-camera images of Erebus Crater, which is about 300 meters (about 984 feet) across. Erebus Crater dwarfs the landing-site crater, "Eagle Crater," which measures about 22 meters (72 feet) in diameter. And, it is nearly twice the diameter of "Endurance Crater," which, at 130 meters (430 feet) wide, has been compared to a stadium. The camera's red filter was used for taking the images in this mosaic. It admits light with a wavelength of 750 nanometers http://photojournal.jpl.nasa.gov/catalog/PIA06341

This stereo view shows the landscape surrounding NASA Mars Exploration Rover Opportunity at the edge of Erebus Crater. 3D glasses are necessary to view this image.

This image from NASA Terra spacecraft shows Mount Erebus, the world southernmost historically active volcano, overlooking the McMurdo research station on Ross Island. The 3794-m-high Erebus is the largest of three major volcanoes forming the crudely triangular Ross Island. An elliptical 500 x 600 m wide, 110-m-deep crater truncates the summit and contains an active lava lake within a 250-m-wide, 100-m-deep inner crater. The glacier-covered volcano was erupting when first sighted by Captain James Ross in 1841. Continuous lava-lake activity with minor explosions, punctuated by occasional larger strombolian explosions that eject bombs onto the crater rim, has been documented since 1972, but has probably been occurring for much of the volcano's recent history. The image was acquired December 31, 2013, covers an area of 63 x 73 km, and is located at 77.5 degrees south, 167.1 degrees east. http://photojournal.jpl.nasa.gov/catalog/PIA20239
