The NASA - Mars Exploration Rover (MER) Opportunity used its Navigation Camera (NavCam) to record this vista looking Eastward across Endeavour Crater, with the Rover's own shadow in the foreground. The NASA - Mars Exploration Rover (MER) Opportunity has been studying the Western Rim of Endeavour Crater since arriving there, in August 2011. Endeavour Crater, which spans approx. 14 miles (such as about 22,53 Km) in diameter, is, by far, the largest Impact Crater that Opportunity has visited since it landed on Mars, Region of Meridiani Planum, in January 2004. The images that have been used to create this mosaic were taken during the 3020th Martian Day, or Sol, of Opportunity's work on the Red Planet (such as July 22, 2012, on Earth)

This frame (which is an Original NASA - Mars Exploration Rover "Opportunity" b/w image-mosaic published on the NASA - Planetary Photojournal and identified by the ID n. PIA 16923) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a normal - meaning "in the average" - human eye would actually perceive if someone were on the Surface of Mars, near the NASA - Mars Exploration Rover (MER) Opportunity, and then looked ahead, towards the Horizon and Sky over Endeavour Crater), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
